Downvolting 5770

post #1 of 4
Thread Starter 
So I posted this in another thread, but the title may have misled people into thinking it was more about temps.
I have an HIS 5770 IceQ5 in the top slot, with an ASUS CuCore 5770 in the bottom slot. My sound card sits between them, under the CFX bridge.
I'm afraid that something might have gotten goofed when I started using CFX. My HIS was previously running about 35C idle and 70-75 under Furmark. After I installed the ASUS, I tried monitoring temps only to find out the ASUS was running over 90C in Furmark, while the HIS kept it's regular temps.
I first tried to make sure the ASUS was running properly in regards to fan speed and direction. I took off the fan cowl and HS assembly and replaced the TIM with Shin Etsu. This seemed to do nothing for temps.
I then looked into the voltage under Afterburner and discovered that the ASUS was running at 1.25V, which is pretty high. I have no idea why a card would be running at that voltage stock out of the box, but since the ASUS bios allows for voltage tweaks I dropped it down to the AMD specified 1.125V and it runs well within spec for temps now.
Problem is, the HIS is all of a sudden running in the 80's during gaming. The card placement is the same as it was before, so I doubt it has much to do with the heat from the lower card. I had already cleaned the HSF and Shin Etsu'd the HIS previously, so I also know it's not that. I checked Afterburner again, and found that the HIS is running 1.2V for voltage now. I guess I never checked it before, because I was under the assumption that the voltage was locked anyway.
Is there some possibility that my mobo is forcing one of my cards to run at a higher voltage that it normally does? I tried running the bios flash for the HIS, but have had no luck so far. I really think it should be running at the recommended 1.125V, and I am almost certain that my previous attempts to OC the card have all resulted in crashes due to the high voltage.
I've also tried Trixx and had no luck with that either.
Any suggestions?
Edit to say; Before anybody asks, I have pretty massive airflow getting to both cards, so it's not an issue of my case or fans.

From my 11 months experience with 5770's, you want to run them at the same clock speeds. The CrossfireX performance is rather good so I didn't give them crazy clocks when paired, 925/1385 I believe.

While I do appreciate the suggestion, it doesn't really help me with the voltage or the temps. Once I can get both cards to stock voltage, I will then look into any possible clock increases.
As of right now, they are both at stock core/mem clocks.
