CORSAIR 8500 Memory problem

[Strikez]

I hope this saves some one some time it sure Pi$$@# me off trying to figure this out. What I figured out finally and maybe its just me but my 550 dollar corsair PC-2 8500 ram will not run using (manual) setup with a speed set at 1066 mhz in the bios. Note if I choose any other ram setting within the 900-1000 mhz setting the bios will post it properly as 8500. Anyother setting it will post anywhere between a pc- 5400 to pc- 7100 ram <--- what the hell is that 7100? FSB does not seem to be the issue to over clock the processor. The strange thing is when the ram is set within the 900-1000 mhz range the CPU-Z program will show the ram running at 533 mhz and as pc 8500 module and the bios will show in the post as 8500. Therefore I think this may be a bios issue. Same problem with the 1305 bios and the bios this board shipped with.

Bottom line if you are having problems Overclocking Check that your Corsair ram is set to manual within the above noted range and check with CPU-Z to see what it is really running at.

Also take it off the SPD settings and put in the proper timings as mine was defaulting to 5-4-4-12. Proper setting for this ram should be 5-5-5-15 runinng at 1066mhz.

Good luck.
At least now I can overclock this sucker

Sounds like three things:

1,) they shipped you the wrong modules.

2,) They raped you on the RAM......

3,) DDR (Double Data Rate) 533 x 2 = 1066

I hope they r the right modules or I really got F@#$# even worse. Nice price but I hate ordering products outside the country (live in canada). With exchange rate shipping and tax, I dont think I got Raped to bad ouch. Actually I had the same ram running in a P5B deluxe before I sold that system and they ran at 1066 no problem. Anyway I have a order in for the Corsair 8500 domintor ver, when I get those I'll if theres any difference. Since CPU-Z show it at 533 I do belive that is 1066 just weird how the setting in the bios are not very accurate for this so called high end ram.

As you know, the SPD info on the RAM doesn't include vdimm information since the JEDEC DDR2 specification calls for 1.8 V only. To ensure mobo compatability, some of the better RAM mfg's write SPD information only for 1.8 vdimm figuring that once you're into BIOS manually increasing vdimm you can then set the timings for yourself.

FWIW, Corsair's XMS2 8500 is certified at 1066Mhz with timings of 5-5-5-15 @ 2.2 V. According to Corsair, the SPD should be programmed at DDR2-800 5-5-5-15 values.
