I now have an Asus GTX 750 Ti card. It's now 4 months after I bought it, and it still doesn't work. The first two months, I didn't have the right type of power cable ready. The third month, I found that the VGA output was disabled at initial startup, so my monitor wouldn't allow me to see anything. I then found a DVI-D connector on my monitor, so I ordered a DVI-D cable. The fourth month, it would display a picture for about one minute on bootup, then go black, but would ignore the keyboard input needed to make the bootup proceed, so I suspect that it somehow stopped the bootup from reaching the point where the keyboard could be used.

Asus provides a number to call for graphics board problems, but not a toll-free number, so I'm likely to have a significant next telephone bill (perhaps two hours on hold).

Their technical support department insists that their GTX 750 Ti uses far more power than the Nvidia specs call far - 350 watts compared to 60 watts, and therefore need a power supply with a greater wattage than the Nvidia specs call for to run the whole computer (650 compared to 300). My computer room doesn't have that much extra power available; it's probably already sometimes using more than enough to trip the circuit breaker if there was no time delay to smooth out the peaks. I've asked about running another circuit to my computer room; the circuit breaker panel has no room for another circuit breaker, so that's not reasonable.

I've already found two more users on Primegrid who've had severe problems using Asus boards.

How many other users here are having severe problems using Asus boards? How many are getting them to work well? Is the ratio of these two bad enough that we need to consider Asus boards about as bad as Dell computers?

What other brands of graphics boards work well? It looks like I'll have to buy another GTX 750 Ti card, but of a different brand, to get one of my computers doing GPU workunits again.

If you bought this card new then I would go to the shop and swap for a new one as it is still under warranty. Or they check and repair it if possible and if not give you a new one.

I have many hardware from ASUS including GPU's and everything did work immediately after I installed it. I think that ASUS can be considered as a very good brand. And that is also true for Dell, I run several Dell's without issues.

However my favorite brand is EVGA, and nowadays I only buy GPU, MOBO and PSU from EVGA, for replacements or new builds.

But your ASUS GTX750 should work, go back to the shop.

Greetings from TJ

I now have an Asus GTX 750 Ti card. It's now 4 months after I bought it, and it still doesn't work. The first two months, I didn't have the right type of power cable ready. The third month, I found that the VGA output was disabled at initial startup, so my monitor wouldn't allow me to see anything.

Is this the only gpu in the machine? Wndows has a very bad habit of disabling resources that it thinks aren't being used during startup, a gpu with no monitor attached is a good example of that. A simple "dummy plug" can fix that.
http://www.overclock.net/t/384733/the-30-second-dummy-plug A second option is to plug in a 2nd monitor during the startup process and then unplug it once windows is up and running.

Same problem I had, call an electrician you may be able to get double breakers that put two breakers in the same slot a single breaker is in right now. I ended up getting three new 20amp circuits for my basement pc's that way.

Buy yourself a "kill-a-watt" device, Walmart sells them for about 20 bucks US, and plug it into the wall and then plug your pc into it, this will tell you exactly how much wattage your pc is drawing. Remember though startup usually takes more wattage then the just running does. Most people upgrade their power supplies when they start gpu crunching as most pc makers put in the minimum wattage power supply they can get away with when they make a pc, it is cheaper and their profit margins are higher. There is no need to put in an 850 watt power supply for most people who will never need one if the pc is only drawing 235 watts as it comes off the line. Dell is notorious for this, they will put in a 125 watt power supply if the machine only draws 100 watts.

I have a gpu, or two, in almost all of my machinea and every one has had the power supply upgraded to a 750 or 850 watt one. Yes it's overkill, but you don't want to be pushing the power supply to it's limits when crunching 24/7/365 for 5 years or so. I run AMD 7970 gpu's and Nvidia 760 gpu's.

Not needed - the UPS I use for that computer includes the equivalent. It says that the computer uses up to 170 watts when running BOINC on 7 CPU cores and barely using the previous graphics card, which probably needs heatsink cleaning, but the heatsink is unreachable. It's a GT 440, with Nvidia specs that say it can use 65 watts. When I let BOINC use that card, it used to work but now soon overheats.

The computer's from HP, so I assume they used an adequate power supply for the previous video card; the new video card uses 5 watts less. I'll consider upgrading the power supply if I can first get another circuit added. Probably only to 450 watts though, since HP provides a part number for a suitable 450 watt power supply, but no higher. The computer's frame doesn't leave enough room to use an GTX 760.

I have six Asus GTX 750 Tis on a variety of Haswell Z87/Z97 motherboards (Gigabyte and Asrock), 2 cards per boards. They work great, and the part about needing a larger power supply is total nonsense, as has been mentioned above.

However, the black screen is another matter. I suspect a BIOS incompatibility there, especially if it is an older motherboard. If your motherboard has a BIOS update, then try it. Just buying a different brand of video card may not fix it.

Can you remove the card and just blow it out well with a can of compressed air?

I'm not sure you need to stick with an HP brand power supply but that doesn't make alot of difference, except for cost, since you are case limited in your gpu options anyway. If you are unsure if another brand will work I would just stick with the known HP one that will fit.

Since you are still having problems with the gpu have you tried plugging in a different one, or even just a cheap one in the same slot and see if the pc boots up just fine? If so you probably should be calling for a warranty replacement and just end this. If not then it could be a motherboard problem and then you have bigger problems. The one other thing I would do is unplug everything you don't need to boot up the pc, the network cable, the printer if any, the cd/dvd, anything except the hard drive, gpu, mouse and keyboard just to see if it works then. If so start plugging things back in again, when the machine is off of course, restart and see what is causing your problems.

Do you have a power supply tester? It's possible the power supply isn't up to snuff anymore, have you blown it out lately too? Be extremely careful if you use a compressor to blow things out, it's very easy to over speed fans and stuff and make things worse, cans of compressed air are best.

1. The computer where the new board works uses a BIOS and runs 64-bit Windows Vista. The computer where it doesn't work uses a UEFI instead and runs 64-bit Windows 7. Does this have anything to do which which board should work and which shouldn't?

Another brand of card might work, but it is hit or miss at that point. Good luck.

Can you remove the card and just blow it out well with a can of compressed air?

It's fairly easy to remove, and I have some cans of compressed something, so I may try that. I can't see where to aim it in the old card, though.

Another brand of card might work, but it is hit or miss at that point. Good luck.

Since it uses a UEFI instead of a BIOS, I'll look for an updated UEFI instead.

If any of you have made a GTX 750 Ti card do GPUGRID workunits properly, what brand of GTX 750 Ti card did you use?

The terminology is a bit confusing, and I don't claim to be an expert. I think that you are correct that UEFI is not BIOS, but is the successor. However, in my Gigabyte Z87 motherboard manual, it refers to it as "BIOS" that can be booted into either the UEFI or Legacy mode, depending on the OS. I think that "Legacy" refers to BIOS used in Win7, and it is really only Windows 8 that uses UEFI mode. But whatever they call the firmware on your motherboard, and update might help, and so might a different video card, but there is unfortunately no guarantee.

If any of you have made a GTX 750 Ti card do GPUGRID workunits properly, what brand of GTX 750 Ti card did you use?

Can any of you with both an Asus graphics card and a device for measuring the amount of power the whole computer uses let me know how much power the computer plus the Asus card uses when running some GPU workunit? I've thought of the possibility that the extra power requirement for the Asus cards could be only during bootup.

Running two GTX 750 Tis on a Gigabyte Z87 with a Haswell i7-4771 (two cores supporting the GPU, four cores on other BOINC projects and two cores free) draws about 234 watts from the wall. That is with a Gold 90+ percent efficient power supply. I don't think the startup current is the problem, or you would not see the initial screen at all; any surge would be less than a second or two.

I've now tried a second GTX 750 Ti, EVGA brand. It doesn't allow booting either, even though the EVGA specs say a 300 watt power supply is adequate.

The EVGA customer service department has a very different idea of what is going wrong, though - a BIOS that just won't handle booting with a GTX 750 Ti (any brand) installed. They pointed me to a site for downloading updates specific to this model of computer; I tried the BIOS update offered there and it made no difference.

I looked into returning the ASUS GTX 750 Ti; the online store only allows such returns within 30 days after buying them, and only for getting another board of the same model rather than returning the money.

I contacted HP, trying to get another BIOS update that allows it to boot with a GTX 750 Ti. The answer was that the motherboard of that computer is not compatible with any Nvidia-based graphics board more recent than a GTX 550i, which implies that I can no longer make that computer run GPUGRID GPU workunits.

After looking at the websites mentioned when I contacted HP last night, I decided that the person I contacted at HP last night does not know the difference between the hardware options I could have chosen when ordering that computer from HP and the hardware upgrades I could have bought and applied later, not necessarily from HP. The boss of their customer service department was asking for feedback on how the support went, so I sent that information to him this morning. I'm hoping that this will persuade HP to offer another BIOS upgrade for that model of computer that will allow booting with a GTX 750 Ti card, but I'm not sure how much to hope for this.

I've thought of another possibility to investigate - buy a new power supply for each of my desktop computers with the wattage rating of the one currently in the other computer, install those, and at the same time, swap the graphics cards between the computers. This won't increase the total power needed to run both computers, but if the other desktop will boot with a GTX 750 Ti, may allow me to resume running GPUGRID GPU workunits on the other desktop.

That brings up an interesting possibility for you...instead of doing ALL that buying and swapping how about taking the troublesome Asus card and swap it into the pc with the biggest power supply right now? If it works you have found that the 300 watt psu you are using is not big enough and you have a solution. BUT if it doesn't work then you are faced with the very real possibility that the card is just faulty.

That means that I have to stop running BOINC, or anything else, on the computer showing the problem. I've done it long enough to show that the ASUS card works in the other computer, but do not plan to make it permanent.

The graphics card in the computer with the biggest power supply needs too much power to run on the other computer, and the computer room does not supply enough power to just put a bigger power supply in the computer with the problem and still run both computers at the same time.

So the card DOES work, when you put it in the other machine with the bigger power supply, but it won't work in the machine with the smaller power supply, did I get that right so far? AND you can't put a bigger power supply in the 2nd machine because the circuits won't handle it, again right? Sounds you may be in a pickle then until you either run a new circuit for the pc that needs the bigger power supply, or put that pc somewhere else.

I've looked into adding another circuit. The circuit breaker box does not have room for another circuit breaker, so that would be difficult and expensive. Moving to a different building that already has another circuit might be a possibility.

Talk to an electrician, they make double breakers that will fit where a single breaker does now, they take up the same space as one but are actually 2 separate circuits. My own electrician was able to do that for me and I now have 3 20amp circuits just for my pc's.

There is such a thing as drawing too much thru the whole circuit breaker box, but again your electrician can help you decide what is or is not possible.

Mine even added a 'whole house surge suppressor' so no more outlet strips with them built into it. It also means my every outlet in my house is on the surge suppressor! It was about $150 US dollars installed for me because he was in there anyway.

Brands i kinda trust.
Asus
EVGA
MSI
Zotac (not really sure about this one)

Brands that are on the warning list for me.
Powercolor
Gigabytes (sometimes there make shit stuff.)
XFX
PNY

I thought about replacing the power supply in each computer with one of the rating of the one in the other computer, so I could make more changes without increasing the total power used.

HP offers only one wattage rating for the one currently with no problems, and I don't have sufficient information to choose one that HP does not list.

I've asked if a nearby apartment building has two circuit breakers, rather than just one, per apartment. The owner isn't sure, but plans to ask someone else.

I'm in a rather small apartment, not a house, and with no upstairs.

The circuit breaker panel for the whole building has about 3 dozen circuit breakers, with no room to add more. Each of the 16 apartments has one 15 amp breaker, 120 volts, for both its lights and its outlets.

Pairs of apartments share one of the 8 electric water heaters. Probably a breaker for each water heater.

All 16 apartments share one kitchen and one dining room, which use breakers not shared with the apartments.

I've seen 20 amp, 30 amp and 60 amp breakers used in other buildings; not enough access to the circuit breaker panel to check if this building does also. 240 volt circuits, using double breakers that fill the space that would otherwise be used for two single breakers, are available for high wattage appliances.

Older buildings, but seldom the newer ones, use fuses instead of circuit breakers.

Electricity for showers? We must use a different word for what you mean - our showers use only hot and cold water.

In the UK we have electric showers that are only connected to the cold water supp;ly. The water is heated within the shower unit on demand.

Of course we also have the same type as yourself which is connected to the hot water supply.

Finally, an answer from the owner. All three of the buildings have only one circuit breaker for each apartment, and all three have no more room in the circuit breaker panels to add another circuit breaker.

Months ago, GPUGRID had a link to some company that offers computers with three GPU board slots. I've lost that link since. Their computers were offered mainly for gaming. Do any of you know which company that was?

I'm also looking at some HP computers that will have more CPU cores, each hyperthreadable. Hard to find information on how much power they would use, though.

I found the information on how to find power supply ratings for HP computers where this isn't something you can choose when configuring the computer.

On the store.hp.com web page where you have selected which model of computer and would normally click Customize & buy, click Specs instead to find more ratings. Scroll down to Power Supply.

I've found an HP model with a power supply only a little above the maximum rating I was planning; I'm looking into whether changing the CFL light bulbs in my apartment to LED bulbs will free enough power to make that model acceptable.

On another subject, do you know of any computer brands other than HP that will stand the 24/7 heavy use needed to run both GPUGRID and some CPU BOINC projects?

I build my own PC's and they all run 24/7 on various BOINC projects with no problems. I use standard motherboard brands: Asus/ASRock, Gigabyte or Biostar, whatever has the features I need for that particular machine. For reliability, the most important factors are the quality of the power supply and the ventilation, both of the case and the CPU and GPU.

For power supplies, I use Seasonic or more recently the Rosewill Gold models; you want a high-efficiency (90%+) one to minimize heat in the case and power supply. Also, get a good CPU heatsink/fan; I usually use the 120mm ones, but a good 92mm fan will work also. And the GPU should not only have a good heatsink and fan, but not be overclocked very much (they almost always factory overclock to some extent).

Finally, be sure to get a case with good ventilation, with room for a 120 mm exhaust fan at the rear and a 120 mm side fan blowing into the GPU.

But if you have real power problems, a good uninterruptible power supply (UPS) is also required; some projects do not tolerate crashes due to power loss very well. I now use the Cyber Power "pure sine wave" ones, since the provide a sine-wave output that works better with high-efficiency power supplies that use PFC (power factor correction) circuitry.

There is nothing wrong with HP; I have used them myself, but you can do better by picking your own parts.

How can I pick parts so that the motherboard, the graphics board, the power supply, and the case will be known in advance to work together, with NO metal cutting? That question is the main reason I don't choose the parts myself yet.

My power problems are mostly strong limits on how much total power my computers can use; I already use a UPS for each of them, since one of the BOINC projects they participate in has been know to have workunits run for 6 months with NO checkpoints.

This site will tell you what is compatible and what is not... as well as parts that have not been tested for compatibility.

Why anybody would employ UPS for BOINC escapes me. If you are running something FAR more important fair enough.

The second GTX 750 Ti gave the same problem. I've since found that the problem is actually with the motherboard, a Pegatron IPISB-CH2. That model of motherboard is known for having problems booting properly when using any Nvidia-based graphics board with a GPU of a generation more recent than the Fermi generation. It also has problems using the more recent AMD GPUs. I've decided not to use that computer for GPUGRID any more.

My newest computer, with a GTX 980, is now trying to get a GPUGRID task; none seem to be available now.
