I'm at a hotel with slow internet(hence the triple post). You can find it yourself, google has it right there. My internet is too slow here to load pages like OC3D(I tried to show benches to the 570 guy).

Guys, I did this unlock: http://www.techpowerup.com/articles/overclocking/vidcard/159 Have I only unlocked the shaders or flashed the 6970 BIOS completely over the 6950? I'm using an XFX 6950 2GB, the flashing went through without a hiccup. Is there a risk that it will go wrong?

Only thing about any OC or a flash to higher bios even more so, is that it does in fact shorten the life span of said over clocked component. No doubt about it. Don't excpect it to last as long.

First question is what is the threshold of this flashed bios life span? So far 6 months and counting, most have been successful thus far. No one can say how long it's going to last until they start to die. Speculation.

Second question, if you can afford to gamble your money and it's worth out of the performance you gained during that span of time is to you?

Senator is right, "people always take a risk whenever they mod anything hardware or software", here on OCN we take those chances and feel thrilled by it with a sense of accomplishment. 99% of us on OCN do it. However no need to personally attack someone btw.

As for warranty, a flashed 6950 voiding the warranty is 100% sure. So even if it's not the bios when your card dies that did it, don't expect an RMA. You won't be able to disprove it.

I think this thread has gone it's course and common knowledge on OCN with the 'OC.

Actually I have overclocked old CPUs that are still running today. I overclocked a 600MHz Duron to 1GHz, with stock cooling, about 10 (or more) years ago. I used that system for a few years, and when I upgraded the Duron guts went into my spare/guest computer. It was used for another couple of years until I upgraded again, then my comps guts went to the spare computer, the Duron guts went to an office computer. The office computer was used for a couple more years before the upgrade cycle happened again and now the Duron is running a system that drives a VGA splitter to test up to 8 monitors on a test shelf. It's still running great. I had other systems I had overclocked the CPU in that I sold (the motherboard, CPU and memory). No one ever phones me complaining that the system I sold them died.

Of course, I wasn't quite overclocking them to the extreme overclocks we see here at OCN. But then again, flashing a 6950 to run at 6970 speeds is not very extreme either. I am not overclocking my cards, they are both running at stock 6970 speeds with an improved fan ramp.

My point is that, although you are correct and overclocking things does shorten their lifespan in general, many CPUs and video cards will still last a long time even if they are overclocked. If they are cooled well, they should be ok.

Having said that, I still think anyone flashing a 6950 to a 6970 should run the fan faster, and anyone purchasing a reference 6970 might also want to run the fan faster. Before increasing my fan speeds I could get these cards both into the 90c area and it scared me a little. I suppose it shouldn't have because my old 4870 could peak at about 101c when I really tortured it, but then it didn't cost me $700 like my 6950 and 6970 did.

Hello all.

I followed one of the guides on transforming 6950 to 6970, and everything worked fine (i just changed the number of stream processors to 6970's number). Then i tried changing this bios further to move the overclocking limit beyond 880 mhz, and when bios was written to card, i only get BLUE SCREEN when booting windows 7...

So, i moved switch on card to position 2, and card boots normally and works (as 6950)... Now, I would like to "fix" the card's no1 bios, so that i would again get the 6970... How do i do that without changing switch to "1" position - where i cannot boot into windows (because of blue screen). Thanks!

Put it in the 2 position, boot into windows, then change it to 1 and overwrite.

Boot into windows, then change the position of the switch. Now reflash the card with the stock BIOS you (should have) saved before you did the first flash. Viola, back to a stock 6950.

If, for some unknown reason, you did not back up your bios before the first flash, you will have to look around on the net to get your stock bios to reflash your card with.

Failsafe is write protected. Otherwise, as mentioned boot off #2, flip to #1 reflash.

To weirdgod, don't mod the clocks that way. If you want to bypass clock limits, use racerx mod.

*Also, if you attempt voltage mod with RBE, only use the gpu registers. Any other way will = bluescreen.

Hey Anthraxinsoup :

It'd be a great idea if you can have a link on the first page to those who didn't copy their original 6950 BIOS before flashing who have to flash it back. bulb.gif

just google it

Also there is a 69xx club where it's likely more appropriate to ask about it.
