yet another mobile barton thread

[AWhackWhiteBoy]

Mobile Barton 2500+
IQXFA 0348 XPMW
DFI Lanparty NFII B

2.4ghz = 12x200fsb@1.9volts
60C is the hottest i can get it with intensive Prime95 action but it usually stays around 47C

i can get windows to run great and stable at 1.75volts, but prime95 gives errors. the only time i can get rid of the prime95 errors is to jack up the voltage and heat. doesn't the voltage seem a bit high for this core just to get that 200mhz? anyone else have similar results or am i the only one that needs to push that much voltage for so little?

edit: my cooling...

I think the most desireable stepping is the IQYHA... 1.9 volts is a little high, especially with air cooling. As a rule, I never go above 1.750 except for a few hours to test and benchmark to see where the max of the chip is.

It definitely sounds like you need to get a Thermalright heatsink, either an SLK-900a or an SLK-947u. Your $10 TR2 would be fine at stock speeds, but it's not an extremem overclocking heatsink.

theres actually only a 4 degree difference between my cooler and the SLK-900, i don't think this would justify spending $50 :\

is there a big differenence between the SLK-900 and SLK-900a?

but this wouldn't solve my voltage issues...

do you really need 1.9 volts to hit 2400mHz? I'm at 1.65V right now at 2400mHz

i wouldn't worry to much about the voltage or the heat, neither is too extreeme and stablity is what counts. i have been running my 2500+ at 1.97v to just to get 2175mhz, granted it isn't a moble but it has been running that way for well over a year and it is doing just fine. tops out at 67c running prime, with globalwin cak-II heatsink and a 27cmf fan for cooling.

You're hardcore But really these cpus are so darn cheap that if they die after a year it doesn't matter anyway - and they probably won't. There have been at least two recent threads on barton heat and the consensus seems to be that up to 60-65 is fine if you have to. I'm still tinkering with my desktop 2500+ at 200 fsb and it looks like it's going to be high 50's or 60 when all is said and done, but I"m not worried about that, and for volts it will be needing 1.75 to 1.8 (still figuring that out, although prime 95 aside it's rock at 1.75. I just want p95 to be stable too, just to say it is).

I think you nailed it right here. That TR2 is the culprit. You cannot be hitting 60C and expect that thing to stay stable. Now 60C might be ok if you are running at stock speed, but you are running that thing 600 mhz over it's stock speed and hitting 60C?! That's why it's not stable. It's well known within the overclocking community that the higher you overclock your CPU the more it becomes sensitive to heat. My mobile 2500 runs stable at 2585 Mhz with load temp of 50C. But when I bumped it up to 2688 @ 2.0 volts, I have to keep the temp below 47C. I lowered the fan speed on my heatsink and the temps went up to 52C before Prime 95 crashed.

thats what i figured,i guess i'll live with 2.4 ghz and high voltage with a cheap heatsink for now. maybe if i get anxious over the summer i'll get something silly and bump to 2.55
