Motherboard: Asus P5LD2 Revision 2.0
CPU: Pentium D 830 3GHZ
Memory: Crucial Ballistix DDR 2 667 "3,3,3,12"

CPU overclcoked to 3.6GHZ, FSB:240, Mulitplier locked to X15
Memory Speed at DDR2 640, but timings at "5,6,6,18", are the timings bad?, is it safe to reduce them?, option in BIOS to do it but what shall I drop them to, don't want to damage memory.., just want to run memory at near enough stock speed with same timings.., but overclocking CPU makes it tricky..., also anyone know what value for the FSB will give me stock memory speed of 667MHZ?, is it safe to overclock memory beyond that speed, eg..767MHZ?..


OK, just upped memory speed to DDR2 800MHZ, and have timings of 5,4, 4, 15..., but memroy voltage is 1.8v, when it should be 2.2v, so going to sort that out..

Yeah your timings are very loose. You're running very close to the RAMs stock speed so drop them to 3-3-3-12.

A 250fsb will make the RAM run at 667Mhz on the 2.66 multiplier you're currently using.

It is safe to overclock the memory over its stock speed by loosening the timings and/or raising the voltage a tad.
 
Well if your RAM was at 640 and your FSB was at 240, that would mean the RAM's on a 2.66 multiplier. Hence a FSB of 250 would have your RAM running at 667. It might not be labeled as 2.66 on your board.
 
well tried a 250FSB overclock but the CPU was not having 3.75GHZ!!!, it's is a pentium D afterall, the 90NM version...., dropped down to 3.6GHZ and memory running at DDR2 400. I think i will leave it at that as any changes to the memory result in games crashing....., but my radeon x1800xt is stable at 690MHZ. overlock...., left the ram on that alone as overclocking it causes stability issues, why is it the the cpu/gpu are easy to overclock but when it comes to memory it is just to tricky...,
