Unlock 6950 to 6970

[killablade]

Apparantly it's possible to unlock a 6950 to a 6970 by flashing the bios, or tweaking the bios in a way that it unlocks the full chip. This is possible with almost all current 6950's. Recommended is that you check the card for stability after you've done it. Warranty will be lost.

I'm probably not allowed to link to other forums, so just google "unlock 6950" if you want to know how to do it.

you lose your warranty if you do that.

heh, i hinted at this yesterday

i was the first to flash a 6970 card and davetheshrew was the first to try it on a 6950

it's the same process i used to flash my 6970 bios

i left instructions for atiflash in the OC3D Review ASUS EAH6970 thread

or just grab a copy of ATI Winflash 2.0.1.13 and do the whole process from within Windows

Oh theres already a post about this, I didn't see it. I made a post about it sometime tonight, I think it got deleted lol. Thats pretty awesome nonetheless.

This is cool to say the least, but there is a reason why they locked the core right? Maybe a bad or under performing 6970 was flashed to a well performing 6950? What I'm saying is, if you flash a 6950 to a 6970 will it perform like it should?

So people aren't of the thinking that the fact you can grab one of these for £215 and up it to say stock 6970 performance is the way to go at the min?

I'm looking to buy a new graphics card in the next day or two and would like some opinions. I was all set on a 570 from either Asus, EVGA or Gigabyte but they are all around £300.. Getting a 6950 and unlocking it to 6970 spec does seem appealing.

Think I'll put this question in it's own thread so I can check back for opinions tomorrow.

Yer great see how that pans out in the long term !

the 6950 has 2 6pin connectors and the 6970 has 1 8pin and 1 6pin. its possible that at extreme levels this unlocked card will encounter problems

Basically your makig sub standard sillicone do more than it was ment to with no warranty for £220 sounds like bit waste of money because pretty sure not going pan out well in the long term. Extreme levels are you kidding it would just be under volted or not not have the right power phase the components are design to opperate like a 6950. It will not have long life time on average but sillicone is so hit and miss who knows what happen in the long term (18 months down the line). That why warranty is great.

The 6970 carries 6-pin + 8-pin connectors instead of the dual 6-pin connectors attached on the 6950 (300w vs 225w). Also, the 6970 has Hynix H5GQ2H24MFR? R0C memory chips rated at 6000 Mhz running at 5500 Mhz stock while the 6950 has Hynix H5GQ2H24MFR T2C chips rated at only 5000 Mhz Running at 5000 MHz So even after successfully flashing the 6950, you may still have to lower the memory clocks to have artifact free rendering. Dual 6-pin connectors instead of? 6-pin + 8-pin connectors will possibly cause problems under extreme power draw and nullify any overclocking potential.

Agreed though seen alot people saying there 6870 are going wrong I worry to what the long term side effects are but with such new card theres just know way of knowing what they are with such new archtecture.
