Help me clock a 2500+

Monstermunch · 27 Feb 2006 at 20:04

I'm gonna be upgrading soon and thought I would give clocking a try cos for my new rig i'm going for an Opty.

Current spec is in my sig - the multiplier's locked so I can't mess around with that, means I have to do a hard reset on the CMOS :mad:

Thought these may help:

Best starting point is the overclocking guide at the top of this forum

Yea I tried that but every time it involves me having to do a hard reset on the cmos. Cos my multi's are locked!

Out of interest. What's your multiplier locked at?

11 x 166Mhz

Have you tried increasing the FSB?

Monstermunch · 27 Feb 2006 at 23:16

No I haven't. I tried following the steps in the guide and it just led me to several ahrd resets of the cmos. The full extent of my ocing knowledge lies with old P1's & P2's using jumper switches on the mobo! :rolleyes:

I'm pretty sure that the only thing I can do with the fsb is using the uncremental steps, and changing it straight to 200mhz I thought might be a bad idea!

Your ram is only 333mhz, which is probably whats causing the problems. Try raising it's voltage a little and lossening the timings (3,8,8,11) worked fairly well when I had a 2500+

Monstermunch · 27 Feb 2006 at 23:27

Right i've managed to set my fsb to user defined and have increased it to 175mhz. My ram timings were at 2.5-3-3-7 and are now at 3-4-4-10. CPU @ 1930mhz from 1830mhz

I know the ram I have is pretty naff but what do you think i'll be safe increasing the fsb to?

hm samsung pc2700, iirc that stuff used to top out at 180-190mhz. but it MAY do 200 with low timings like 3-4-4-10.

best off buying a gig of value pc3200, then at least you'll be able to get a reasonable speed out of your cpu.

I know but i'm upgrading soon, this is just to tide me over a little till then, don't want to spend any money now or it will reduce the amount I have to spend on a new rig.

BTW it's now at 2ghz

fsb @ 182mhz. Havn't got time now but i'll run prime later.

iraiguana · 28 Feb 2006 at 15:57

sounds like it is going well, i think that the only way of getting a lot out of it would be to get some cheap pc3200 ram really. But increasing th volts on the ram and cpu will always help u push it a bit further.

have fun! try not to burn it up too badly

, remember temps are good upto around 60-70 max. (well ment to be rated to about 90 from what i remember, but i suspect things would go horrible by then)

ajgoodfellow · 1 Mar 2006 at 00:16

Often with the XP2500+ you can just change your FSB to 200Mhz from 166Mhz and this will give you an XP3200+

You just need to help your ram along to 200Mhz

iraiguana · 1 Mar 2006 at 11:36

and dont forget to raise the vcore when it starts to fail. then u should get a few more mhz out of it.

MadMatty · 1 Mar 2006 at 12:06

Id like to add that on my own 2500+ , it takes 1.775v to get it to hold stable at 11x200 which gets a little toasty especially on the amd provided cooler (around 65c+ under load).
