2.4 Celeron

[PHakeDC]

I am thinking of overclocking my low-end Celeron and make it run at 2.80 gigs. In the old days we used to fiddle with jumpers and such, but dunno about the current generation of CPU's and their setup.

I have a Shuttle mobo with the Intel 845PE chipset, 100/133 FSB and supports Pentium 4 HT with ease (at least that's what the manual says). No idea on the DDRam speed (its not DC-400 Mhz, that's for sure). The fan seems to be geniune, but I have no way of telling how much temprature the CPU core is working at.

I want to get higher frame rates for the current crop of games, since my XFX GeForce FX 5200 seems lacking in the performance department. The system itself is quite stable when it comes to desktop applications, but with a 128 meg video card I expect a little bit more for my money. The reviewers did not warn me the performance hit will be so steep. My friend has an Athlon 1600 plus a GF3 Ti-200 and his benchmark scores are twice as much as mine. Granted, lack of L2 huurts 3D performance, but a 3DMark 2001 SE score of 4250 is simply ridiculous.

The question is, should I overclock the Celeron or just jump ahead to the GPU OC board?

wow, my piii system gets 2x the score!

Well i am sorry to break it to ya but the ti5200 is an abysmal performer, dont let the 128mb of memory fool you because the GPU chip is just too slow.

The celeron does have 128mb of L2 cache, but even that is very little, you are right in think that overclocking will help because it is neutered by its 100mhz (400mhz qdr) fsb. Most celerons are good overclockers, if you enter the bios you will probably see some FSB settings, just increase the fsb and the cpu vcore (if necissary) and you should be on your way to a faster system.

Thanks for the reply. I will attempt an overclock later today. What about cooling? Do I require an extra fan? Also, please explain how to increase the vcore for a 3.0 gig overclock. thanks again

download a program called prime95 (google it)

Increase your fsb (i would say pump it right up to 110mhz and go in smaller incraments from there) run prime 95 for an hour and if you dont get any lock-ups or instabilities then go back and increase the fsb, but if you get lock ups or instabilities than you may need to look at a variety of things

The cpu may be causing the instability, in this case increase the vcore in the smallest incrament allowed by your board and try again (dont let the temp go above 55c full load though)

The memory may be at fault, in which case you will need to relax the memory timmings and/or increase the vdimm voltage, up to 2.7v is fine (2.8+ if your memory has heat spreaders) also if you are running a memory : fsb divider switch it to 1:1 as it will yeild the best overclock.

More system specs would be helpful to point out what is likely to limit you. You may want to post in the graphics card forum how to overclock the 5200.

About cooling, it would be helpful to get a new heatsink although if your temps stay below 55c it's not totally necissary, but it will lead to a higher overclock also, after you have found the max speed you can run stably run prime 95 for another few hours just to make sure everything is 100% stable.
