Hi all, want to ask something here
system spec:
P4 2.8GHz (northwood)
Asus 865P (800FSB)
1024 DDR400 kingston value RAM (4.3ns)
R9600P VGA

When I OC my system, anything more then 210MHz external clock (840FSB) and In 3DMark03 CPU test benchmark, artifect are everywhere.....only that benchmark, normal 3D benchmark, application all runs well. CPU stress test also didn't crash, running for few hours, CPU temp max about 50c, mobo temp max 45c

Anyone knows where the problem lies?

and also, will adding heat sink to that ram helps my overclocking?

thanks alot

Erm, the RAM, KVR400X64C3A/512 .......Hynix chips BTW
The mobo, it's Asus P4P8X, northbridge supposely i865P (not PE though)
And yeah, AGP was lock at 66.66/33.33

Anyway, in normal 3D rendering, nothing wrong as far as i know...only that 3DMark03 CPU test, lots of artifect

Tried that, but unfortunetly it didnt work. The artifect still the same

wow, it really works...now its gone
thanks alot

BTW, i'm not sure what is that....will it affect the performance?

hmm....one more thing
I notice it goes back to 00 after restart...so need to set everytime I boot up?
I try to find inside the bios, but there isn't any such option...

I'd like to ask about the voltage for core and DRAM

1. in the bios, it's set to auto...does it means it'll automatically adjust for stability when I oc? Or better to manualy set it

2. I once tried set in the bios, vcore to 1.5875, but in Windows, Asus Probe detect it at 1.64V Which reading is accurate....is the BIOS setting there set it to absolutely 1.58, or it's just a rough figure?

3.whats the safe margin for vcore and also the ram

thx

want to ask about the RAM dividers
I'm using a Asus P4P8X (865P chipset)
2 stick on KVR DDR400 ram totalling 1GB RAM with dual channel config
P4 C (2.8Ghz)

Under the DRAM Frequency setting which sets the divider, there's only [Auto] and [400] setting....no [333] and [266]
So is my divider locked at 1:1 ratio?
And what cause this problem? izit the chipset, ram or incompatibility issues?

thx in advance

yeah, i'm aware of that
but my problem is that there are only auto and 400 option in the dram freq there. So i was wondering why there isn other ratio

i thought so too, in the manual shows that option as well...but somehow it seems to be lock at 1:1
wonder if theres any way to tweak the bios or something to enable the feature
