Help Overclocking A8N-Sli Deluxe

[GooN3r]

Ok stock seems to be good so now I want to try my hand at a medium over clock.

There are a lot of features on this board I don?t understand. I assume before I begin I need to disable cool n quiet? What next just switch overclock profile to manual and raise the CPU frequency. Do I need to change the PCI Express clock or CPU multiplier?

The only this I have done so far is to change the memory timing to 1T. What other changes do you recommend?

Here are my specs:


Asus Asus A8N-SLi Deluxe nForce4 SLi (Socket 939) PCI-Express
A64 3200 (Winchester)
OCZ 1GB (2 x 512MB) PC3200 Dual Channel Platinum Series EL-DDR REVISION 2 CAS2
XFX GeForce 6800 GT 256MB DDR3 TV-Out/Dual DVI (PCI-Express)
2x WD 74Gb Raptors in RAID 0
Tagan 480W PSU

Come you guys I know you can help!!!!!

Lower your HT Frequency to 4x. Your goal here is to keep the FSB less than or equal to 1000MHz (5x200). Lower your DRAM speed from 200MHz to 166MHz. (these settings might have different names on your board). Leave your CPU multiplier at stock setting (10). Raise your HTT to 210MHz. (210MHz x 4 = 840MHz FSB) Boot Windows and run Prime95. If you can run it a few hours then CONGRATS! your overclock is stable and you can go back and raise the HTT (FSB) again. That will get you started.

Ok I set the HT frequency to 4x, the muiltiplier to 10x and CPU frequency to 210Mhz. However it locked up during 3dmark05. What should i set the CPU and DDR voltage to?

Also you said to lower the DRAM speed to 166Mhz, do you mean Max Memory Clock. If so the lowest setting is DDR200. What setting should I use for Cas latency, RAS to CAS delay and Min RAS active time?

I have also switched off cool n quiet!

Yeah, Max Memory Clock is what I meant. Default for your memory would be DDR400. Just bump it down to the next lower setting from there and see if you can run 3dmark05. If you still have instability then loosen the RAM timings to 3-3-3-10. If still unstable then set your CPU voltage to +3.3%.

It been slow progress but after a BIOS flash I am Prime95 stable @2300Mhz on just above stock volts

Sweet! Now get that baby up to 2400MHz and make that chip a $630 3800+!
