8GB XFX GTR overclocking, how did I do?

[Arthur_Dayne]

Hey,

Stock, for reference:

97W avg power draw
69C avg temp (stock fan profile)
1288MHz core (2000MHz mem)
1.1375V

Heaven results:

avg FPS - 55.9
min FPS - 25.9
Score - 1409

Max OC:

124W avg power draw
64C avg temp (100% fixed speed, will be finding a middleground later)
1460MHz core (2050MHz mem)
1.225V (+90mV)

Heaven results:

avg FPS - 61.1
min FPS - 27.4
Score - 1539

So how did I do?
Without touching voltage, the max I could sustain was 1360 core. I know the voltage is high, but I only plan to keep this card for 1, maybe 2 years (3 at a push). Is there actually a max stated voltage?

Looks good, right in the 480 range and don't worry about the voltage level. GFX cards today won't allow you to give enough power to cause any damage

 

[Saul Goodman]

Looks ok but honestly I think you'll be able to find a better middleground around 1380-1400mhz with lower voltage and therefore lower temperatures and fan speed.

My 4GB card does 1400mhz on the core with +24mV. I assume you have power limit increased? make sure it's actually holding the clocks you are setting.

I know your average GPU Watt was 124, but could you tell me what your Max Watt Spikes were during Load on your Benchmarks? Trying to see how this compares to my card thanks.

Can you get the mem clock up? I would say if you push your core clock that much I'd like to see it paired with 2150 Mhz - 2200 Mhz memory

Here are some benching results I got so far

Firestrike Extreme

1375/2100/-0.025 1340/2000/0 1400/2000/0 1400/2250/0 1425/2250/0
Graphics Score 6314 6039 6287 6393 6537

Graphics Test 2 24.28 23.33 24.18 24.74 24.95

and a plot of the data

I don't know why it says 4 GB there, I got 8 GB according to wattman & gpu z. I'm a little bit surprisded that my score is higher although my clocks are lower. It could support my theory that memory is rather importat or did you use other settings?

 

[Saul Goodman]

I wouldn't believe those software power draw readings...........

 

[idkfa]

I hooked up a wattmeter to my outlet.

It reads around 166-170 W during idle. During Heaven Benchmark it goes up to < 320 W (saw a spike to 340 W).

This would leave around 150-160W for increase during load for CPU+GPU. Power draw in idle for the GPU is 25 W. With my readings this would account for + 75 W for the GPU leaving + 75 W for increased power draw from the CPU.

+75 W for the CPU doesn't seem unrealistic to me.

Or do you think the readings are completely useless? Any better way to measure them? If GotEmAll used afterburner too for the readings at least he can compare his values to mine I think (which was the point of providing them).

^ don't forget to subtract 15% wattage from the outlet reading (PSU power efficiency, your 600W BeQuiet being 80+ Bronze I guess)
