Realized today, that when I am running anything REMOTELY RAM intensive (even simple programs like WoW, which doesn't require more than 512MB) on my new computer, that there is a Physical Memory Dump happening often, so after looking into things a bit more, I realized my mobo (Asus P5N32-SLI Se Deluxe) is only capable of running on 667 or 533 MHz ram stable, however the computer came with a set of dual-channel 800 MHz Corsair XMS2 series memory cards @ 5-5-5-12. How exactly can I make the memory run @ 667 rather than 800 MHz? How should I adjust the timings?
You don't have to do anything. Your ram can run fine at ddr2 800MHz. Your problem must be softwarematic. Your ram is probably running on a divider or asych. Timings and Devider settings can be changed in bios.
Its on a fresh Windows XP ----- SP2 install with all automatic updates, and WoW + WoW:BC installed with iTunes and a few ripped (I own them) CD files, nothing else. All programs 100% legitimate. Mobo drivers 100% up to date, video card drivers 100% up to date, all hardware drivers, for that matter, 100% up to date, but yet the system crashes when playing WoW for any extended period of time (more than 30 minutes - 1 hour). I have not tested it to see if it crashes without playing WoW or other programs (IE: Idling). Reading through the manual and it states that the board itself runs stable at 667MHz or 533MHz (which, after doing a bit of research on Google across some review and tech sites, I have seen to having this be a common issue with Intel boards, that work far better at a lower clock setting, than a max of 800+, while a few have said they run stable at 800-1066MHz, but in that case, I do not know why the hardware would be failing).
verfiy that ti's the RAM first... http://sp2004.fre3.com/beta/beta2.htm run that on blend... it pushes things A LOT harder than WoW. several candidates powersupply is ---- and is causing instability under high load(beleive it or not, graphics cards suck up a lot of power) motherboard is ---- and f's up under high load(memory controler is on it) CPU is ----... gives bad info... as for downclocking RAM, simply go into BIOS look into it, and find a memory divider, set it to the corresponding one. Also, if a baord doesn't support a memory divider, it wont' run the RAM at that speed. It can't, it goes to the next highest setting on the SPD.
You should use divider 1:1 for best performance. That will end up 266mhz(if you have a c2d), so effective ddr2 533. Most ram will be able to do cas 3-3-3-10 at those speeds, but to be safe put them on 4-4-4-12. What volts are you giving them? Still, using a higher divider means more mhz, means more bandwidth..
it means a higher theoretical bandwidth peak. if the RAM is retreving data, then ti's all but worthless. regardless, most RAM does 3-3-3 @ 667(or so I hope)

go into BIOS and raise the timings on your RAM by 1 each cas-tras should be at say 5 just to be safe. as it is, basically all that is known is that something is not stable. Try it under small FFTs, if it crashes then, it's likely the CPU. also try running memtest http://www.majorgeeks.com/MemTest_d350.html what power supply are you running on?
I can't even get it to boot anymore, the origional error i had a month or so ago for bad bios checksum returned, so basically... I am parting out the computer (4GB Memory, 574GB Raid-0 array, 8800GTX, e6600) and going out to buy a laptop (assuming they let me pay monthly for it, due to myself having no credit thus far I am not sure if they will). Sick of dealing with it. Got it December 16th, 2006 and I have been unable to use it for more than 24 hours total to this day, so its just not even worth my time anymore. Company won't take it back, take multiple weeks to respond to me asking for an RMA #, and then take 4-6 weeks simply to RMA the part.
No boot? Try using CPU, vga and ram only. Does it gives any beeps? Your ram is probably needs more volts.. Corsairs 6400Pro modules are rated 5-5-5-15 @ 1.9v
