E6400, DDR2-667, new to overclocking, help pls :)

Post by Roxor » Sat Oct 10, 2009 9:00 pm

Hi, I'm fairly new to the whole overclocking business.

I have an E6400 core2 duo with 4gb of fairly standard DDR2-667 5300 RAM. I have an ASUS P5L 1394 motherboard. I was running version 0107, but flashed it with (*i think*) the newest version 0607 (i was hoping i might get some more options).

I've turned off the power options, my PCI-E set to 100. I can't seem to go past an FSB of 295. I do have fairly bog standard Ram (the make is Amicroe). I've had a fiddle with the Ram voltage, increasing it from 1.8V to 1.9V and also changing some of the ram timings, 5/5/5/12.

Is there anything else you could suggest or do you think i've reached the peak of what my ram (if that is the bottleneck) is capable of.
Some CPU-Z stuff listed below, if that helps. Thanks.

I had a E6600 that I could not get to 3.0Ghz to save my life. I kept on reading how everyone was getting well over what I was getting.. I think some of the earlier Core 2 Duo's weren't good overclockers. Hopefully the guide on this site helps.
