Trouble Overclocking XP 2000+. Ideas?

[Parn]

Here is the setting I have:

Athlon XP 2000+
256MB Crucial PC2700
Epox 8k3ae
Visiontek GeForce 4 128MB
The CPU is a AGOIA stepping.
Heatsink is Alpha PAL6035, and using Arctic silver 2. But CPU temp is always around 55-58

I increased fsb 1mhz at a time. When I got to 138mhz fsb, 3dmark 2001 SE would suddenly close on me, going back to Windows desktop like it was never running in the first place. I left 3DMark2001 SE to run a loop of 90, and it did that in between somewhere.

So the question is... what's the next step?

I would look at upping the voltage on the sqaure and RAM a tad and maybe relaxing the timings to the RAM as well...You do have a good HS/Fan and compound added I assume?
Also keep in mind that some of the earlier stepping on the CPU were not great OCer's

any help appreciated.

What LED said: raise CPU and RAM voltage and relax memory timings in BIOS.

 

[Parn]

Just to make sure, relaxing timing... is going from 2.5 to 3.0 or so. right

 

[mechBgon]

Yep.

Ok, so I increased CPU voltage to 1.775 from 1.75.

I just completed 120 loops of 3D Mark 2001 SE benchmark.

I did not relax the mem timing. Is it necessary to do so?

 

[Soulkeeper]

only if the mem isn't stable at whatever speed it is running at
just experiment
that's what it's all about

Ok, I am now at 139mhz fsb and running stable. I will come post again when i hit my next wall to borrow the expertise of the ppl here 🙂
