Hey guys,

I have a AMD Athlon 2500+ XP Barton OC to 3200+ on Gigabyte 7N400 Pro Socket A 462, 1.5gigabyte ram, ATI X1950 Pro AGP 512mb ram GDDR3, 160gigabyte drive, fairly new expensive 550watt PSU with enough Amp or what ever The GPu requires.

I have a problem with slow gaming everything is slow, Counter Strike is like 80FPS with my old card ATi 9600xt it runs at 100+fps, Playing Counter Strike Source it use to be 45Fps consistent now its just 10FPS.

I had the CPU/Computer Cleaned few months back because it was running really slow because i tought that the problem is the CPU cooler being really dirty. When i got it back it runned every game really fast, but after a month it went back to slow gaming performance again. The cpu is still clean i dont understand whats wrong with it.

I think its the CPU temperature is too high, it is running 79'C right now OC at 3200+.
Im guessing 79'C temperature is not good for a 2500+ Barton Clocked to 3200+.

79c is definately too high!! CPU is rated for 85c max (95/100c for mobile versions)

Check that the fan is running at right speed but sounds like the heatsink isnt making proper contact for it to be running that high. Even with the stock hsf it should only be around 50c (ish)

What vcore are you at?

-------------------------
Opteron 165@ 2970MHz (330x9)
DFI Lanparty Ultra D/ TR Ultra 120/2x1Gb G.Skill @250MHz
BFG 8800GTS (750/2000)

For best performance you really need to run in dual channel. If you have a matching pair of 512MB sticks just use those in the dual channel slots.

I have the same CPU which like you is running too hot 64c (with the case sides off) but I notice that the unit is running at 2100MHz the CPU fan is running at 2860rpm and the core Voltage is 1.7 which I suspect is too high.

Stock for a xp2500 is 1833MH at 1.65v so if your ocd to 2100MHz at 1.7v then thats not too bad but 64c under load is a bit high but not dangerously so. Main thing is it stable at that temp? Pressume that is with the stock hsf?

I realize this is an old post, but could you tell me what you did to get the OC to 3200? I have a 2500+ on a GA-7N400L and cant get it to OC for anything...

Here is some info that should help you to get your system going.
But in short, PC3200 DDR RAM, good PSU, sufficient cooling, to begin with.

This is exactly what I was looking for!

Thanks so much!
