Problem exceeding 958Mhz

post #1 of 4
Thread Starter 
hey guys, im having issues trying to get my OCZ DDR2 1066 SLI Ready RAM to go past 958MHz on my ASUS P5N32E SLI board. the second i OC it by 1 more MHz and save/restart, my comp fails to boot and i get one continuous BIOS beep code. i have already cranked the voltage to 2.3V, manually set the timings of 5-5-5-15, and i have unlinked the FSB to the memory. i am fairly unfamiliar with overclocking so, other then the voltage, i have no idea what could be causing the system to lockup. any help would be appreciated.

Pull two of the dimms and see if it works. It may be a problem with running 4x1GB.

Crazy beat me to it... 2x1GB kits might be rated @ 1066, but if the motherboard's memory controller isn't up to the task, you'll have issues ramping them up to that speed with all DIMs filled...

I would try each kit individually for 1066 and see if one of them is incapable of it... memtest each kit to be sure... If they're both capable of 1066, it might be your motherboard's memory controller...

Also, are these kits double sided, single sided or mixed? There have been some known issues with running double sided with single sided sticks

thanks for the replies. so what you guys are saying is the problem is either 1 of my kits of RAM is not capable of running at 1066 or the motherboard cannot support 4 sticks @ 1066? i will test my RAM with memtest86 later as im kind of out of time right now. assuming both my kits are capable of 1066 then there is no way to actually achieve having 4 sticks @ 1066 short of hard-modding the motherboard?

im sorry, how can you tell if they are single or double sided? these kits are exactly the same and i bought them at the exact same time, so chances are whatever one type is the other is the same.

an added question, if i cannot increase the speed of the RAM any further, could i tighten the stock timings of 5-5-5-15 2t? if so, which timing do i start to tighten? how do i know when the timings are reduced enough?
