Howdy, I have a new system on the way. I have not built my own puter in a few yrs and want to double check some of my Bios settings with you guys before it gets here.

System:
2x ZOTAC ZT-88TES3P-FCP GeForce 8800 GT 512MB 256-bit GDDR3 in SLI
http://www.newegg.com/Product/Prod [...] 6814500006

XFX MB-N780-ISH9 LGA 775 NVIDIA nForce 780i SLI Intel Motherboard

Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor
http://www.newegg.com/Product/Prod [...] 6819115037

OCZ Reaper HPC Edition 8GB (4 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

Microsoft Windows Vista Home Premium SP1 64-bit English 1pk DSP OEI DVD

Western Digital Caviar SE16 WD4000AAKS 400GB 7200 RPM SATA 3.0Gb/s Hard Drive


First:
Install Vista x64 using only 1 stick of memory. Use default CPU and memory timings as they load up in bios. Then load on other sticks of memory (8GB).

OC Goal:
I want an ultra stable long-term OC so i'm thinking 3.6 Ghz.
(Clock multiplier 9x, CPU FSB 400 MHZ,
PCI Express bus frequency to 100Mhz
Memory Multiplier = 2x for 800 Mhz memory speed
More memory settings: 2.0V @ 4-4-4-15 2T

Do these settings look right? Any other suggestions?

Testing:
Should i test the system with just Prime96 64 bit version or both 64 and 32 bit version? Other recommended testing? Then I'll benchmark with some 3D benchmarking progs.

Those settings look right. You may have to relax the timing to 5-5-5-15. I haven't really used that RAM so can't really comment.

You may need to increase voltage to 2.0v first since standard voltage is 1.8-1.9 on most motherboards.

Is the 780i the chipset that corrupts data while overclocked? Or is that the 790?

Both the 780i and the 790i have/had the problem.

Not sure if it is fixed now.

Thanks guys. I was told the 780i was the way to go. But we shall see.

Shadow, which part of bios are you refering to that i may need to increase voltage on? For the processor or ram?

For the RAM. That RAM needs 2.1v. The motherboard usually provide up to 1.9v. So you might have to increase the voltage manually.
