Gaming to test out your card for stability... Your miles will vary.

I prefer OCCT even if the load is generally unrealistic for games.

Bump your voltage a little bit and see if you can get BF3 stable. That is usually all it takes but definitely keep trying.

i can do 1200 core 1.292 volt staple in evrything crysis2 bf3 but if i lower the volt to 1.245 it will be staple in benchmark but not in games
i think its driver issue and AB

However, in terms of what you were saying about voltage, I believe +125mV is a hardware limit. I know it's relaxed on the Lightnings, maybe some other nonref cards too, but reference cards have that hard limit of +125mV, no matter what you set in Afterburner.

Here is what happens to me to:

My cards are 1.049v stock, both are good ASIC 86.1% and 86.5%. So for what I just passed was .201v over stock. Any less and Fail. No OCP kicked in, but I am testing with UOM set to 2 now instead of 1.

Its strange because hwinfo reads same voltage when on load. ~1140mV but with higher voltage in AB i get higher clocks which makes no sence to me.

Hambone07si can u check ur voltage in hwinfo at 1200mV and 1250mV? I wonder if they are the same. You have to test it under load. Because in idle hwinfo shows ~25mV less then in AB no mather what i set it to. Thats weird too. In idle through my card runs 1175mV on load only 1140mV..

And with my OC i figured that 7950 is 2-3% worse performer then 7970 at same clocks. So i'm really satisfied with my purchase. Especially cuz i got my card for 300€ unused:)

The cards have built in vdroop

I assume its preety noisy, my ears are preety sensitive so i prefer less perfomances for better acoustics.
My card is about 60-62C in Crysis Warhead, 1.049V.

Yes it gets pretty noisy. Thats why i will buy the copper adapter and some old silent cooler for the card for about 30€. I'm looking for cheaper, coolest and quietest i can get. I figure that with the copper adapter i can mount just about any cooler on the card as long as it fits on the card.
Example:
http://di1-3.shoppingshadow.com/images/pi/79/ca/93/106457599-260x260-0-0_arctic+arctic+cooling+accelero+s1+passive+vga+cool.jpg

I think this one should fit onto the card. The good side is that you can get these old coolers very cheap because they are old and they were build for cards that go up to 100°C so they should cool pretty good.
Just want to make sure that this would work. So if someone here has any experience or though on this please share:)

EDIT: I found someone already doing so:
http://forums.hardwarezone.com.sg/hardware-clinic-2/%5Blongsiew%5D-ek-vga-supreme-hf-hd7970-cu-adapter-copper-does-wonders-3643912.html

I have a question tho. If i install this will my ram be too hot?

Yes but i don't get it why is card unstable at 1170mV in AB and stable at 1200mV in AB where in both cases hwinfo shows the same voltage is being fed to the card.

Btw, don't open overdrive if you use either crap hehe.

I have to use overdrive to set power control to +10% wink.gif
You can not do that in Trixx tongue.gif
BUT, I have not had any problems using overdrive in combination with Trixx ...

I think we can expect new beta drivers later this week.

I was on RC11, uninstalled it (NOT using Atiman) and installed 12.3 WHQL.
No need for these 2 files to run Trixx here...

I am now at 1030/1575 and testing, voltage is 1.049V. I hope its stable.
1050 Mhz on same voltage is not stable, it crashed in crysis warhead.

Well 1.250v in AB feeds about 1.175v under load

1.275v in AB feeds 1.200v under load which is passing my 1.174v (1.049v + .125v)

PLEASE DON'T TRY WHAT I DO. I have the mind set that I am going to blow the caps off my cards doing what I'm doing, so if it happens, I'm not going to be upset, I don't want any of you coming back at me if you damage your cards. I can care less as it's a hobby and only money. It can be replaced.

With 1.275v and under load, you thought you've heard cap squeal, HA, you should hear these things biggrin.gif

You really got your 3930K to 4.8GHz at 1.375V? Mine needs 1.45V for 4.8GHz... frown.gif
