I just got an AMD board and cpu (FIC 1st AN19C/AMD XP 2000+) used from a friend, but the thing wont run at the normal 133 clock speed. i had to downclock it to 122 before it would remain stable under cpu-intensive applications. Windows will lock during boot at default speed, and even at 128 it will lock doing data transfer. Right now it's at 111*F at idle just using IE. It jumps to 125+ at normal clock speed before it locks up on me. The cpu fan is ~5000rpm. What steps should I take to fix this? I assume a bigger fan, but why doesnt the stock fan do the job? What kind of fan/heatsink should I get? I want something very quiet, inaudible if possible. Another thing is the north bridge heatsink fell off while he used it. It worked fine for a long time like this, and it's back on there now pretty tight, but could this be related? Thanks guys :good:
what voltage is the CPU at? I'd use this heatsink, see how the fan works out and if you still get high temperatures switch the fan out. http://www.newegg.com/Product/Product.asp?Item=N82E16835103146 That's the heatsink I use right now. Works very well with a different fan and Arctic Silver5. I have http://www.newegg.com/Product/Product.asp?Item=N82E16811999458 that fan running on it and it's pretty quite. It's quieter than my Vantec Stealth fans I'd say and move much more air.
1.76/1.78v (is that normal to variate?) That heatsink looks identical to the one thats already on there. Is it any different?? Heres a pic of whats on there now http://putfile.com/pic.php?pic=6/15903000185.jpg&s=x4 When you install heatsinks, do you only put the thermal grease on the center of the cpu? In all the systems I'd ever built (several hundred) I slathered the CPU with it, but my buddy only put a layer on the core.
1.75V is the norm for that CPU. Do like your buddy did: use only a thin layer of thermal grease. Slatering it on like that makes the thermal paste act as an insulator for the heat, and I can almost guarantee you that's where your overheating problem lies. You need only a paper thin layer on the core, and that's it. I posted a response awhile back on why thin is good over here
This heatsink is mounted with a tiny bead of paste, so that can be ruled out. By slathering it all over, i just meant a thin layer across the whole cpu and not the core alone. Oh well, anyway. The f'er refuses to boot at all now. I shut it down (idling at 120*F) to install a new sound card, and it decides it wont turn back on. The cpu fan twitches when the power supply is plugged up, then another twitch when pressing the power button. Won't do jack other than that. It sat unplugged for a few hours and still wont boot even without anything hooked up, so I dont think its overheat protection. The onboard lan lights are on and doing their thing so the PSU isnt totally dead. *sigh*. Computers don't like me.
I'd clean off the CPU with some isopropyl alcohol first and then reapply a thin layer to the core. I don't know what type of thermal paste you're using, but if you're using some type of silver-based stuff, it could be messing with the bridges on the processor packaging. I had an XP2000+ with the Palimino core and that thing ran very hot at stock speeds. I had a Thermalright SK-7 and would see temps over 50*C, boardering on 60*C. I eventually bought a newer CPU with a cooler core instead, but you may want to invest in a different heatsink. I don't think the one you have is up to task. I'm not sure about the CoolerMaster that NF linked, but it does have a copper insert, which might help to disappate the heat. Even so, you might check out a ThermalTake Silent boost. If you want decent temps, you're probably just gonna need to buy a high-performance heatsink. The Palimino's run hot and there's really no way around it. It could be a different core, but by the temps you hav e, I'd wager it's the Palimino core.
I'd get a new heatsink even if you fixed it. I've had some expierience with that heatsink and it's just an engineered pile of metal. Doesn't even cool a sempron very well. Thermaltake Silent Boost looks cool.
I used to have a Palomino 2000+ and it ovverheated too with the stock hsf. That cpu simply runs hot and there's no way around it but a quality hsf and grease.
