P5WD2, Corsair?

P5WD2 back port...SATA?

K, not anything to do with overclocking, but on the P5WD2 Premium, what exactly can I plug in to the back SATA port? it doesn't look like a regular SATA connection, and guy at computer store didn't have a clue what kind of cable would go in it?

all 667 shows up as 4300 stock.. you have to manually set the speed in the bios if im not mistaken.

Depending what dividers I use (DDR speed in MHz), the boot-up screen will assign the matching PCxxxx speed to it. The 5400 should work just fine in it, but you'll need to go into BIOS Advanced->Jumperfree, set OC to "manual" instead of Auto and adjust the DRAM dividers to achieve DDR667 or DDR675 (default speed). With the DDR speed set to 667/675, it should show up as PC5400 when it boots.

While you're in BIOS, go into Advanced->Chipset menu, disable DRAM by SPD and plug in the spec latency for the memory (4-4-4-12). If you let it work on Auto, it will default to something like 5-5-5-15 and you'll be missing a lot of performance for no reason

cool, thx guys. I'll try that when I get home.

so far, have cpu installed with zalman 7700cu, idle sitting at 56...thinking about reseating it to see if I can drop it a couple degrees...

But also put a zalman vf700cu on my bfg 7800gtx...gpu core is sitting at 42 idle

top, new question

back sata port? there three red ones and two black, all normal looking on my board. i think you're gonna have to find a picture of the board and circle the component you're talking about.

It's not in a "normal" location if that's what you're talking about, but it's a normal SATA port. It's in the back so you can install the included Serial I/O port in the back to plug in/unplug external SATA devices (like external HDD enclosures) easily...

NM, found it.
