A warning to unlocking the 6950 2GB.

post #1 of 90
Thread Starter 
The 6950 2GB shares the same RAM with the 5770, while the 6970 has a much tighter and faster RAM. I thought I would let everyone know that's what kills the 6950s when you unlock them. Yes there is a difference, and it is noticeable.

Same RAM, here is the 6950.

As you can see, that's the same RAM. The different numbers just are different, they are the same RAM, timings, ETC. Go look at the timings in BIOs. Flashing to just a shader unlock is safe.

This only happens if you flash the 6970 bios onto the 6950. If you just unlock it you have no problem.

Source?

Unlock shaders + OC to 6970 speeds is much safer and risk free. (At least the unlock shader part.)

Doesn't matter at all, as unlocking the shaders and then overclocking nearly yields the same performance.

Also where in that review does it say anything about the RAM? I'm not reading the entire thing. That is also a non reference card.

The highest memory clock so far was 1450 MHz on some HD 5770 cards - and those used exactly the same memory chips as the HD 6950 PCS++.

That's why i only do shader unlocked bios on my 6950s (or any 6950 that went thru my hands). I don't trust the fully flash biggrin.gif.

It says it on the page he posted even, and compare them, same exact ones just with a 2 in there. They have the same timings and everything. Unlocking the Shaders is fine, never said that.
