my cpu is 2600 ghz, and cpuz shows my ram clocked at 371 mhz i.e. cpu/7. wht does that mean, why dont i get rated ram speed of 400 mhz. other thing is that my ram is cl6. i can easily bring it to cl4 . but the speed remains same i.e. 371 mhz. would someone tell me how do i get my ram run at full 400 mhz ? and should i lower the cas latency? and wht overclocking options have i got?

"wht does that mean, why dont i get rated ram speed of 400 mhz" It's a bit of a complex formula but the way AMD configures the RAM speed has a lot to do with the CPU multiplier. Since your multiplier is 13x, the RAM divider becomes 7, meaning the RAM runs at CPU speed divided by 7. In your case, the RAM runs at 371MHz (742MHz DDR). Here's a chart that shows the relationships between the reference clock, CPU multi & RAM speed: http://www.overclock.net/amd-memory... If you want the RAM to run at full speed, increase the CPU referenece clock to bring the CPU speed up to 2800MHz. Try 216MHz. That will put the CPU at approx 2.8GHz & the RAM will run at 400MHz (800MHz DDR).

I was trying to overclock the cpu using overclocking profile, but mostly i get overclocking failed kinda msg in bios. wht if i change the mulitiplier to 12x? and plz plz tell me abt cas latency coz i know tht lowering latency is good, but wht else should i know??? lowering the lateny at same clock speed, is it good or bad. i have heard u should decrase memory speed if u want to lower the latency.

Do NOT touch the latency settings (for now) & do NOT use OC profiles. If you wanna do it right, you have to overclock manually. If you change the multi to 12x, the RAM will run at 400MHz but the CPU will only run at 2.4GHz. Is that what you want?? I doubt it. You have a decent board for overclocking, you just have to learn how to do it. Here's what you gotta do to get things up to speed...I'm only gonna list the settings you have to adjust: CPU Overclocking = manual CPU frequency = 216MHz PCIE Overclocking = manual PCIE frequency = 100MHz Processor Frequency Multiplier = x13 (or Auto) Cool 'n' Quiet = disabled Plug & Play OS = no

I did wht u said. CPU Overclocking = manual CPU frequency = 216MHz PCIE Overclocking = manual PCIE frequency = 100MHz Processor Frequency Multiplier = x13 (or Auto) Cool 'n' Quiet = disabled Plug & Play OS = no >>> I didnt find this entry anywhere. And i got this: DRIVE_IRQ_NOT_LESS_OR_EQUAL Techincal info STOP: 0x000000D1(0xF84C7E70, 0x0000002, 0xB4D6BCBA) RtkHDAud.Sys -Address B4d6BCBA base at B4AA5000, Datestamp 4ab8cbfa Beginning dump of Physical memory. One more thing, dont i have to bump up the vcore ? and is it really needful to disable cool n quiet?
