Patriot Viper PVS32G1333LLKN 2x1gb DDR3-1333 7-7-7-20 Experience or input wanted.

[WARDOZER9]

I have 2x 2gb kits of Patriot Viper PVS32G1333LLKN which is rated for DDR3-1333 @ 7-7-7-20 1T and 1.7v. After a day of tweaking for 1600mhz I finally got it to 8-7-7-19-27 1T using 1.725v on my XFX 790i Ultra Sli board.

I have tries C7 but even with 7-9-8-24-41 2T with 1.9v this memory just plain will not do C7 @ 1600mhz so I pretty much gave up on C7 @ 1600mhz.

Does anyone have any experience with this memory? I am having issues getting my system to boot with a 400mhz FSB but will sort that out this weekend but for now I'm trying to get the most out of the memory that I can.

I would love to know what IC's are used on this ram so I can get a good idea of how far I can go on how many volts so if anyone knows where I can get this info or if someone has it it would be greatly appreciated.
