Jack, I'm back...

I meant that there's no GTX bios or GTX voltmod that works, your ram grows until 1050 because you're just lucky...
GTX ram are different hardware, so the limit could be 960 for someone or 1050 to someone else, but it's not a matter of bios or voltmod.
The juice is this, I didn't want to focalize on scores (and it's true that T2600 gives more score, I do know it)...
The fact is that there's no way to get GTX features, not by tweaking, not by bios modding...
If the limit is 960 for Andre, you're just lucky to get 1050, but 1050 is the limit of your hw, with or without all the tweaks you're speaking of...

A bit overvolting is useful, but it's not a new and it doesn't strictly regard a "modded GTX bios"...
you can get the same on a Go vid modded bios, but the 1320 Mhz of GTX ram are so far just because different hardware...
