Help Running PC2-8500 not at PC2-6400

post #1 of 16
Thread Starter 
Hey guys, I just purchased 2x2GB Modules of OCZ PC2-8500 5-5-5-18 Ram for my ASUS Striker Extreme 680i motherboard (it is an A1 revision)

I am having extreme difficulty posting when i set the Ram to 5-5-5-18 1066Mhz @ 2.1 volts. Isn't the ram meant to be rated at this speed? It just keeps crashing.

I only have a 1333Mhz FSB overclock on my Q6600 (3.0Ghz) so I'm not running anything insane.

The only speed I can run the Ram at is 4-4-4-12 @800Mhz (2.1 volts)
Can anyone help me out? I have tried Linked 5:3 mode, no boot. Have tried unlinked and setting the FSB to 1333 and the Ram to 1066 (after adjusting the timings) nothing.

Any help would be appreciated.

have you tried raising the voltage above 2.1volts? have you triedf 2.2volts?

also is you bios fully upto date? if it isnt, goto asus website and get there latest bios and update your mobo and try that, could be that ur board was made/bios installed, before trued 1333fsb was fully supported, im not really the brightest when it comes to intel, imw aiting for my new upgrade bits to arrive atm, but thats my advice, update the bios

BIOS is fully up-to-date. I have tried 2.1Volts on the memory but not 2.2 volts as it mentions on the OCZ website that it is rated at 5-5-5-18 1066Mhz @ 2.1 volts.

Ive reset the CMOS multiple times in an attempt to get it working correctly. Then gone through and reconfigured all the voltages individually etc etc. Still nothing. 4-4-4-12 @ 800Mhz is the only thing that works. Oddly enough.

Yeah I know it does, I'm overclocking it to 1333Mhz so that it can be 3.0Ghz overall. Its not the OC either as i have run the CPU at 2.4Ghz and 1066 FSB on the ram still didnt work.

Yep I have the ram in slots 1 and 3.

I dont understand why it wont run at 1066Mhz at 2.1 volts if that is what the manufacturer website states that it should be able to do.
