Hello guys, I read the guide you have posted on overclocking core 2 duos. I have read many posts here on the oards as well, and i am still having trouble. I am new to the OCing world so im scared i might screw stuff up. I have been trying to OC my rig for the last couple of days now and still cant get what i was aiming for. I would like to OC my rig to around 3.2ghz-3.4ghz, untill i get a water cool system. Here are the backbones of my rig:
Is it possible for me to achieve my target OC? Any help would be greatly apreciated. If possible could it be referenced to the P5N32-E SLI Plus bios. If not, i can manage to figure out the right thing to change i think. ITs wierd cause the P5N board doesnt do normal FSB frequencies for Ram and CPU, it formats it in "quad pump" witch is confusing to me.
I have a 6750 and P5N32-E SLI PLUS it's stable 3.4Ghz @ 1.425 VCore, Prime/Orthos Stable 8Hrs +. I have set the vcore to 1.425, 1.2ht vtt - 1.25, cpu vtt - 1.25 or 1.30, NB - 1.45, SB - 1.5, ddr2 - 2.25. Link and Synk mode worked best for me but I am working on upping it from here hope to reach 3.8Ghz. Leave the multiplier at 8 and see if you can hit 1700 FSB QDR which will give you 3.4Ghz. This board undervolts alot so 1.425 equaled a 1.38 - 1.39 actual VCore. You will also want to cool the heatsinks activley for more stability. I used a fan off an old video card to place over the NB and it cools good, then I placed a fan over the heatsink on the Voltage Regulators that are connected to the SB and everything is alot cooler. I checked with Asus as well it seems as the 0803 is overclocking better then the 0805 bios. I had an issue that when I used the 0805 bios I could not get above 2.8Ghz. It looks like you may have the same ram as me. Set the overclock mode to manual then set it to Linked and then the box below it set it to synced this will bring your ram to 850Mhz but you should be fine. The board seems to work better linked and then synced. As far as your memory timings let me know what the model or part number is and I will attempt to help you set them for maximum overclock or performance. I coudl not get anything in the 1400 to 1600 range to work well but I set fsb to 1700 and bam stable as a rock. I'll be more then happy to help as this board does take a little bit of tweaking but once you dial it in it is all worth it.
