Will also need to flash with the latest KPC ASUS BIOS to increase that vcore limit. Only 1.25 V max, should be able to dump 1.35 V through them for benchmarking, see if they'll budge on the MHz then

Is there a new asus bios? I tried old one, seen some really concerning spikes in memory volts and core. The type of spikes which would kill your card, not small ones.

Really more stressful, is that simply due to the increased temps in the loop due to the cpu load, because just from past experiences game never tend to get close to stress test temps...
Just out of also just out of interest should the 7970 be capable of running mark 11 physics tests just seems to crash on my pc I assumed at the time the physics test was just for invidia cards....

So, what's the highest OC you achieved on water with the DCII? Any chance, with some modding to fit the stock coolers over the universal block for better VRM cooling? That was my initial intention, but now with a full cover block out that seens pointless. Also are you planning getting 4 Lightnings? =)

I always thought most gain in FPS was to be made with the core clock?

At least in my tinkering 100MHz on the memory will get about the same increase as 50MHz on the GPU. Little more, little less depending on what I'm running.

Crysis 2, scales really nicely with memory overclock. That is the game I used for stability testing and I myself was surprised by how much my min fps and averages would increase as the memory clock did.

The difference between two gpus, clocked 1300 core 1700 mem vs 1200 core 1800 mem is 1000+ P score on graphics FOR the 1300 core clocked card.

Its hard to quantify anecdotal evidence btw. Run some Crysis 2 benches and then we have something to judge.

Its not random to overclock in Crossfire, often times Crossfire/Trifire/Quadfires highest overclock is even lower than your weakest card.  Testing clocks willy nilly isn't useful either, I am not advocating that, but you are forgetting that Crossfire adds overhead and additional processes on a cards IMC / GPU.

 

You should really overclock in Crossfire the same way you overclock weakest and strongest cards, Crossfire clocks are often different.  It isn't correct that your weakest card will be your strongest overclock for Crossfire.  I have seen Crossfire enabled reduce the ability to overclock completely (ex. regarding the 5870s.).

 

@All

There is little to zero gain in overclocking your GPU memory.  It helps at really high end setups with Eyefinity and all that, but you guys hit the GPU bottleneck way before you hit the memory one.  Higher memory overclocks are prone to crashing, reduction in performance sometimes, and general instability all around.  Pushing your memory really has one place, benchmarking.

 

Don't forget your memory is all ECC, you can push it essentially till the computer hard locks.  As the error correcting begins more frequently with higher overclocks, you may or may not see glitching/artifact/stability issues, but you will see a decline in performance after a small peak, and decline to levels worse than stock.

A lot of people push 300~400 MHz more on memory then play games like WoW.  Its pointless, 90% of the time, and the other 10% of the time, you are reaching the GPUs limits way before you run out of memory bandwidth.  Same goes for Crossfire, only its a little more beneficial as the VRAM data transfers are using more, but the gains are often negligible or negated by other factors.

 

In short, you don't have to increase your memory speeds.

How did you increase memory voltage to 1.75v? My limit is 1.7v with AB.
