So I flashed my 6950... I have a few questions

post #1 of 8
Thread Starter 
I was able to get a modded 6950 bios that just unlocks to 1536 shaders but keeps the voltages and all that the same as stock 6950, this keep the Pixel Fillrate at 25.6 GPixel/s and the Texture fillrate of 76.8 GTexel/s instead of 28.2 Pixel Fillrate and 84.5 Texture fillrate I would get if I flashed to the 6570 bios.. Would just the shaders being unlocked perform as well as an actual 6970 or do I have to have the higher clocked voltages and such? If I flashed to a full 6970 and had the voltages increase would this shorten the life of my card?

thanks

I would assume you will see similar FPS with your BIOS as you would with a well OCed 6950. 6950 OCed decent amounts could get in Underclocked 6970 range.

I would undo the BIOS and OC it as a 6950. Or go full out and make it a 6970 full speed.

There have been a few studies done by others on here. Unlocking the shaders doesn't make a noticeable difference as far as FPS compared to overclocking the card.

That said, it definitely doesn't hurt to unlock the shaders (modded 6950 bios). Now you just need to overclock the hell out of it and you'll be set.

is it safe to load the 6970 bios on the card and have the increased voltages as well as the 6970 clocks? or will it shorten the life of my card having the higher voltages?

many ppl including myself have the 6970 bios working just fine on the card with 6970 clocks + additional overclocking on top of that ... as far as longevity it shouldn't make a huge difference but it depends on your individual card

but I can't stress enough that if you have any concerns then it's not worth it at all to flash to 6970 bios for maybe 5 extra fps ... modded 6950 bios + overclocking is the way to go, especially if you're only at 1920x1080

There has been a few stories where unlocking to full 6970 caused the card to brick out due to memory voltages and timing. Unlocking just the shaders net you 2 - 3% performance increase and then just OC the card. I have OC both my cards to 900/1350 on stock voltage. I was able to go 920/1400 max, but decided 900/1350 is better suited for me.

Basically this. Your only missing out on 1-5% in frames by not using the fully flashed variety. But I do disagree; just flash the cards to a 6970 there's little to no risk. Worst case scenario you get to RMA and do it with he next one. It's overclock.net right? The juice is worth the squeeze and the card will take it.
