Are Micro ATX mobos bad for GTX 770?

Hi,

After recently concluding that my GigabyteB GTX 770 is (probably) faulty, due to performance issues during games and OC'ing as well as windows desktop refresh rate stutters, I handed it over to the retailer to see if they can find and isolate the problem. I received an email from them today saying the GPU performance is getting bottlenecked either due to overheating or my low-end motherboard (Asus B75M-A). As I know for sure that there's not overheating at all, the PSU too is just fine (CM Silent Pro Gold 550W, as per all the suggestions here), the CPU (i5 3570) is good, it now comes down to the mobo.

I've asked this question before here and I got positive feedback for B75M-A and GB GTX 770 combo, but I'm compelled here to verify it. My apologies for asking the same question. But the context is different this time around as you can see.

Are mATX motherboards really not good enough for GTX 770? Chipset types do not matter here alright, whether it's B75 or H77, but does the form factor of the board have anything to do with good power circulation/flow to the card and stuff?

Please I need to resolve this urgently so that I can decide to return the mobo ASAP (while it's under warranty), if that is the cause.

Thanks very much.

There is no difference in performance between a Micro ATX, ATX or ITX board. It all comes down to the chip set. Now the B75 should easily be able to handle a 770.

What issues are you getting in games and why are you trying to overclock it?

First of all thanks.

Actually I never wanted/had to OC the GPU. It was only due to the fact that I was facing the issues I mentioned in my original post, i.e. minor desktop refresh rate stutters (there are no stutters when connected to the onboard HDMI) and old games from 2007 and 2009 crashing, including falling below 25fps in Crysis 1, which should never happen @ 1920x1080 - Ultra - 4xAA (as per the millions of this card's reviews I've seen so far).

After all this, I tried to OC it, during which I found out that it downclocks to the default 1137 long before hitting the power/temp targets. So I thought if it was due to the mobo being mATX or low-end or something.

For starters have you installed all the drivers for your motherboard from ASUS's website?
https://www.asus.com/Motherboards/B75MA/#support
(Drivers and tools -> select the version of windows you are running)
If you have then update the GPU driver to the latest from NVIDIAs website.
Use MSI Afterburner to measure temperatures, clocks and voltages.

I was using 332.21, downloaded directly from Nvidia's website, before sending the card back on warranty. Tried 334.89 too but it had some problems with directx and there were other issues posted at different forums. A couple of days back, 335.23 was released but I don't have to card to check it.

All the issues I was facing, were while using 332.21 (which is a very stable version). Also, did use Afterburner too for OC'ing and monitoring.

What version of windows are you using?
and it is looking like the GPU is broken.

It's Windows 7 Ultimate x64.

I forgot to mention it before, that OC'ing also was very unstable with this card. At +70 core and +275 mem offset, one time the test/benchmark (with Unigine Valley) was successful, other times not. I really don't have issues if my GPU has lower OC limits, but if it's passing a certain test, it should pass it always, rather than start downclocking randomly while the TDP%/Temp is @ 85%/71C!

Just received an email from Gigabyte support, and this is what he has to say:
"As to the driver version, since we cannot guarantee newer VGA card versions from Nvidia website are compatible with our product, we suggest you to install the driver version 320.49 from our website which we have verified and work properly."

Do you think that is the case?

Thanks very much.

You could give it a go.
also overclocking usually voids your warranty and is not ever guaranteed.
As for temps up to 80oC is normal.

I must wait before they return it to me or ideally replace it.

As I mentioned, OC'ing was just to check if the card had to increase its performance, bcoz almost all the games (especially OLD games) were crashing.

You mean it can hit 80C without any performance hiccups ever?

80oC is a safe working temperature for most GPUs (The new AMDs are 92oC I think)

Ok then.

So I'll await GB ppl to respond now.

Hope they'll test the card the way I want them to, and replace that pathetic thing with a new one.

Well thanks a lot ganon11000, for sharing your expertise. It was very nice of you. Really appreciate it.
