Hello!

My stock 2500+ with stock HSF is running around 47C on hottest day in Vancouver (28C) right now. Many ppl here mention it's safe to overclock the FSB to 200mhz from 166mhz.

But is there a noticeable difference from 166mhz to 200mhz? Is it really worth to to risk it to void my 3 yr warrenty just increae the FSB to 200?



thanx!

i think i speak for everyone when i say DO IT!!!

increase bus by couple of mhz at a time, you dont have to go all the way to 200, monitor stability and temp and increase it to its limit,

"Is it really worth to to risk it to void my 3 yr warrenty just increae the FSB to 200?"
yes. be reasonably careful and you ll be fine.

but my biggest concern is that my stock CPU with stock HSF is running at 47C. That's bit too high for stock fsb imo. At what temp should I stop overlocking then?

and will overlocking from 1.8ghz to 2.2ghz make THAT much difference?



and damn, it's running at 49C right now, but today is like the hottest day in Vancouver. It's usually running around 43C ish

Stop when the system is unstable. That is the only true way of telling if the cpu is too hot, as they all have different thermal characteristics. By the way, ocing an AMD will not void your warranty unless you tell them.

plz list system specs

thanx for the help! I never overclock b4, so i really want to be careful

all right this is what you do first you enter your bios do you know how to do that? then go to frequancy voltage section will may be called something else depending on motherboared then you up your fsb 2 mhz at a time from 166 to 168 if that stable go 170 etc..
you can also turn up your votage to overclock farther if you using stock don't go above 1.75 vcore
200 fsb a good target you can always overclock the multiplyer, you get higher frequancy but less bandwith. if you have any more questions feel free to ask

hmmm. 400fsb is possible, but IMHO i think its unlikely that your PC2700 ram will be able to reach such high speeds.

In the BIOS, do you have access to any multipliers?

And what CPU cooler are you using.

with voltage and relaxing the timmings it is possible...

3 386DX-25's...12 volts...glue and some ln2 and a wicked amount of overclocking and you get a willamantee minus 36 pins, 33.75 million transistors and a couple hundred mhz... :cool:

i am using AMD stock cooler.
July 30, 2003 3:13:05 AM

ok then... stick with the 166Mhz system bus and ram speed, and try raising the multiplier.
The XP2500+ should be unlocked up to 12.5x.
And yes, better cooling is needed for overclocking.

Vantec aeroflow, spire falconrock2, volcano 7+, AX7, SKU800/900, MCX-462 or alpha PAL 8045 are all good coolers, with varying degree's of noisyness.

i still say 200mhz ram speeds are possible with some tweaking...

might get near with slack timings... I had some crucial PC2100 C2.5 stuff that would do 175Mhz@Cas3

..But what would the difference be between, say, a PC running 166 @Cas2 or one running at [for example] 185Mhz@Cas3... Maybe I should tweak my system and see... I've often wondered just how much difference there would be.

Bawoo: It's definitely worth raising the FSB a little, everything can usually cope with small OCs... Maybe 175-180Mhz would be do-able... Oh, and don't panic when you see a BSOD [cos you probably will at some point]
