Hi
I own a GTX 560 Ti DC II card - it clocks really well. I can go 990 MHz on core and 2200 MHz on memory without a hiccup at 1,083v so it's a really good piece staying under 70 degrees on stock air DCII cooler.
Still for last few weeks I was looking for something which will give me some nice performance boost. I decided that my choice will be Radeon 7950 - thought about 7870 XT but I decided not to buy a crippled card.
Anyway - I took the cheapest HD 7950 Gigabyte Windforce 3x. It came with FZ0 bios, voltage hardware locked (flashing - no luck), and it OC'ed to... nothing. It wasn't even stable on stock 1000MHz/core with 1,25v!!!
That card was a disaster - RMA.
I decided to choose between Sapphire DualX Boost 7950 @925 MHz and Asus HD7950-DC2T-3GD5-v.2 - finally, after lot of thinking and reading that v2 cooler is much better than v1 fail, I ordered it. It will come tommorow with Crysis 3, Bioshock Infinite and Far Cry 3 codes which is cool.
Now my question - what is the chance to get this card voltage locked? Why they are being voltage locked (not sure if they are but...) if Asus says on the webpage that it's designed for voltage raising and overclocking?
And finally - if it will be voltage locked is there any BIOS flash option to unlock it?
Thanks in advance, I'm a little beat scared cause this card was the most expensive 7950 available in my country. Still hope it will OC great.
