My GPUz validation... http://www.techpowerup.com/gpuz/7wbgu/

And screenshot smile.gif

338


This was my GPU only.. next up is the Vram

Notes:
-fps in the Furmark Benchmark dropped considerably after 1225Mhz @ 1125V
-left Power Control Setting (PCS) in CCC at 0% because my card did not respond well to PCS

GPUz validation of Vmem overclock... http://www.techpowerup.com/gpuz/zqfxz/

And screenshot smile.gif

Next up is a combined overclock...

GPUz validation of combined max overclock... http://www.techpowerup.com/gpuz/v3s5/

And screenshot smile.gif

338

Conclusion:
Max GPU overclock: 1330Mhz
Max Vmem overclock: 1590 (6360) Mhz
Max combined: 1265 / 1570 (6280)

4.4Ghz i5 2500k

Powertune +20%

Tested on Afterburner and gpu-z

Man, glad to see I'm not the only one, but this sucks!

Can you tell me if you have the Sapphire edition?

Post a pic of your GPU-Z, to see the BIOS version, please.

Here's mine:

Other thing could be Power Play.

OC'd it to 4GHz, nothing. Power tune to 20%, nothing.

I don't know what's going on. I installed the 12.4 beta drivers but it changed nothing.

I even downclocked the 7870 to 500/600 and still... Worst case is Bad Company 2 multiplayer where I'm at 65% gpu load, 50fps average.

I also tried Witcher 2, Crysis 1 and 2, Metro 2033, BF3. All these are no so bad, as they rearly drop from 90%. But they do drop to the 80s%.

Put back my old 6850 and works perfectly. 99% usage all the time.

My CPU load in single player games is about 40-50%, I really doubt this is bottlenecking.


I would appreciate if someone tells me how much gpu usage and fps are you getting in BC2 and Skyrim, or any of the other games I'm testing.


1.)What is your CPU usage at in said games?
2.)What are your in game settings, and associated FPS(per title)?

In the single player mode of those games, usage is usually at 40-50%. In Bad Company 2 is like 80%. Battlefield 3 is 70-80%.

I think this is clearly not a CPU problem, as the guy above has the same problem and he's running an i5 2500K @ 4.4GHz.

Now, my framerate:

I'm playing in 1080p.

BC2: 45-50FPS (all maxed)
BF3: Ultra preset 4xAA, 40-50FPS
The Witcher 2: 50FPS (maxed, except Uber Sampling)
Crysis 1: maxed, 4xAA, 35-45FPS
Crysis 2, Extreme, HD text pack, DX11, 50-65FPS.

The framerates seem right, however I would think that your GPU should be closer to the 90% utilization. Ill let you know how I fare when I get mine. It should be at my place tomorrow some time, I got the Sapphire OC edition.

Take a look what GPU-Z reads as voltage? Also, according to my multimeter readings, the Gpu Tweak voltage set does not set voltage correctly. Cards actual voltages are way bigger than GPU Tweak set.
On my 7850 1225mv set was around 1297mv actual reading. Im sure that its same case here. 1165mv 1330mhz is pretty much utopic.
Another argument is that generally all Pitcairns and Tahitis overclock about same way. 1.1v= 1100mhz, 1.2v=1200mhz and so on. It ofcourse varies depending on GPU leakage (ASIC quality) and cooling efficency, but this math is approximately still solid enough.
The cards i have tested so far:
HD7850 (81% asic) 1225mv (gpu tweak) 1240mhz benchable.
HD7950 (71.5% asic) 1300mv 1275mhz benchable.
HD7970 (77.8% asic) 1300mv 1315mhz benchable.
All cards on stock cooler, around 20C ambient and fans on 100% during benchmarks.
