I have new bios to my HD 7970 card, but I got Fail error when I try to flash new bios using ATI Winflash 2.0.1.18.

So what is the valid command to flash Matrix 7970 bios if I try to use atiflash on dos?

What do you guys consider safest MAXIMUM voltage?

I'm under water so temperature is not a problem.

1.3v
depends on chip also.
I run 1200mhz when I game and 12.6v then and I am on air.
desktop use its way lower.

I hope you mean 1.26 and not 12.6 lmao.

What is the stock voltage for the 7950 boost?

Running at 1200/1500 at 1.15 V /1.6 V respectively; wondering where I am standing in comparison to the boost.

You asked how people are getting close to 11k in 3dmark11 with 7950s and that's how. 3dmark11 weighs the CPU just as heavily as the GPU and thus a true hex core intel CPU such as mine @ 4.9ghz is going to score leaps and bounds higher than your AMD hex core. An 8150 is good competition for a 2500k, but that's all. Not to mention yours isn't even an 8150, much less Vishera. Don't take 3dmark11 scores too seriously though, as any properly threaded application or game will still allow you to perform pretty close to the latest intel quad core (non HT) chips, which is just fine for gaming. Just don't expect to be scoring as high as the big dogs here.
Unfortunately, it's not. I've heard the AMD hex cores require just as much heat dissipation as the intel hex cores or more, and if that's the case, I KNOW an H80 isn't sufficient for an overclocked hex. Why? Because I run an H100 with my 3930k and it struggles to keep temps under 90C peak in Prime95 even as low as 1.39v @ 4.5-4.6ghz.
When I decided to switch back from Quad 680s to 7970 lightnings watercooled, I decided to only watercool the GPUs and leave the H100 loop on the CPU intact. That was a mistake. It's really not capable of cooling a hex core, so I know for a fact the H80 should be about 40% worse due to the reduction in surface area.

Thanks for the info, I have an H100 on the way to cool my 2600k so I'm interested to see how it will perform.

I guess that's the highest step I can take before having to go full watercooling frown.gif

H100 on CPU, Kuhler 920 on GPU
