Hi all,

I'm new to the a64 overclocking but not overclocking. My Asus A7N8X-E with Athlon XP Mobile (Stock 1.8) Running at 2.5GHz with OCZ Gold at 2-2-2-5 and thermalright SP-97. I didn't see the need to go all the way to the newest stuff, so got the K8N Neo2 Plat off ebay, picked up an X2 4200+ and a Thermalright SP-97A, 4 1GB sticks of G.Skill (F1-3200PHU2-2GBNS) from newegg. Still got my XFX 6800 (overclocks/unlocks to Ultra levels) and a Thermaltake Pure Power 480w (W0019).

At stock of 2.2 on CPU and setting the RAM to 200, everything seemed to boot up fine, but I think there might be issues with using 4 1gb sticks. (did the memory map and xp64/suse64 both saw 4gb, xp32 saw 3gb.

Now for overclocking...

BIOS = MSI 1.D (Jan07)
So far pushed CPU to 2640, ram to 480
HTT=240
CPU Mult=11
CPU Voltage 1.4 (clockgen shows 1.3?)
RAM=set to 200 (memtest/clockgen showed 240/ddr480) 1:1 ratio
RAM Timings=2.5-3-3-6-2T
RAM Voltage=2.7

HTT got a little flaky at about 245, so for now stayed at 240 (will try higher later)

Now, here's what I'm having a problem with=Running all 4 sticks!
Both pairs tested with this config for 10hrs in memtest no problem @480

testing all 4GB OCd at these settings just doesn't work (superpi stops in less than a minute, have not tested memtest, but expecting the same results). Loosening the timings didn't seem to help.

I will try at home tonight running the ram at 2.8, but most posts I've seen on this ram say that voltage doesn't seem to make much difference.


Does this board just not like 4 sticks (or 4GB)?
Is my PSU the limiting factor? (See link below for specs)
Does this board play nice with X2?
Seen anything regarding 4GBs in this or other mobos N-force3?
