Doesn't matter because at the Grand Finals the CPU and tweaking will be more important that the VGA card. Even so, the TT 1350W will have trouble holding over 1500MHz 3D11 which any decent Lightning will do !
GPUTweak allows higher volts only if you flash GPUTweak.bat firmware on MATRIX!
The software will work on DCU II also but you will be limited to normal voltage limit (must edit BIOS for higher volts)
Good luck!
You know that power usage gets higher also with GPU clocks, especially on Fermi arhitecture?
The problem is the "wheel of fortune" with CPU binning. If you pick a bad CPU you lose SPI32M and 3DMark01 so you can go home...
If you feed the VGA from 12V1 and 12V2 I think you can reach almost 1600MHz. ~1500MHz only from 12V1 was possible though...
I confirmed with MSI and there will be special signs on the VGA's that will be send and also SN and GPU batches for every single card. This means no IHS removing and no lapping the IHS
Dude... 3DMark01 is even more CPU dependent that 3DMark03 used in EMEA Finals. If you have luck with the CPU you win 2 rounds (SPI32M and 3DMark01) and the VGA will count only in 3DMark11
I'm interested also in how they check the VGA's . Using Extreme Edition Lightning will be better for the sake of fairness because nobody benches that card
P.S: I don't think they will use 3dmark01 because on Win7 with limited tweaks it's absolutely no fun and also MSI lacks a good 01 BIOS for their MB...
Don't think Expander will help because it has 2 x NF200 and also SB is better than Gulftown in Unigine. Maybe some 6500MHz+ Gulftown could match SB at 5900MHz...
