Hello to all,

I'm new in this forum and also a new overclocker. In the last few days I struggled to oc my system and finally I managed to get it stable at 3.00GHz cpu 1500fsb and dram frequency at 450Mhz(5-5-5-15) with a divider 333/800.I don't know much for oc i did some google search and tried it out. My problem is that I can't make my ram to run at 1066Mhz. I tried numerous voltages and dividers but the system was unstable, especially when I tried timings such as 4-4-4-12 the system wouldn't post. Please help me, what can I do to run ram at 1066Mhz? Can you give me any voltage advice? My nb core is at 1,265v and dram at 1,925v.

Thanks a lot

Hello! Welcome to the Forums !

Lets start with the basics :

Set DRAM Timing to 5-5-5-15 (CAS-TRCD-TRP-TRAS)
Ref to Act Delay ( tRFC) to {60}
DRAM Voltage Control to { 2.1 } You can go up to 2.3 volts with these modules.
Set NB Core Voltage to {1.3 volts}

See what you can do with these settings.

You may want to run Memtest86+ avalable here ( http://www.memtest.org ) to see if you get errors at specified timings.

Let us know your results .
