Athlon XP 2500+ to Phenom II X3 2.8ghz ... @ 3.5ghz

Downclock your memory and see what happens. Run memtest86 in windows. I had bad ram and it showed up after about 5 seconds.

I somehow think the mobo doesn't like the SCSI card/config

So your highest stable OC is 3.1GHz w/ stock voltage?

Didn't quite have the webbo's to add the extra voltage for max oc test ... but I got over my fear after some reading and started screwin around when I was sure cool n quiet would still work.

3.5ghz @ 3.60v (in the bios, 3.52v in CPU-Z)
250mhz CPU Northbridge @ 1.310v ~> 1.245v is default, kinna worried on this one but it's a must for stability. It seems like most people are pushing it even higher.
835mhz DDR333 9-9-9-24-1T. I'd tighten the timing's but I've not made it there yet.


Pretty simple OC overall, certainly not the 300mhz NB frequency they reached on anandtech. I don't like the voltage's people are using to get to 3.7ghz and above so I'm iffy on going any further with this thing. I'm pretty positive the DDR3 can get me more out of the NorthBridge, but being that the northbridge took the highest percentage increase in voltage, I'd rather not risk the god like temps I'm getting right now ...

... which leads me to my biggest question at the moment ... How am I getting 18c idle temps and 23 to 24c full load temps?

Every program I've used is reporting these temps and I'm starting to think the temps are not accurate. That is, compared to the temps I've read from other's with these or similar chips.

I'm using a thermal take V1

 

[richierich1212]

Well what are your ambient temperatures right now?

34c case temp though I'll tell you right now, it's nowhere near 90f in this house, ever. These temp reading's are fuxored. The case is open with one side panel removed also (to expose all the cool blue LED's).

My BIOS states a temp exactly 10c higher than the temps I'm seeing in speed fan and core temp, both at load or idle.

The base of the CPU cooler under full load (2 hours of prime 95) dose not even get warm to the touch.

I'm extremely surprised how cool these chips have gotten. I'm thinking I should just add 10c to whatever temp I get through windows, but, I'm interested in finding out why I can't get an accurate reading.

Try touching the actual heatpipes to see if they get hot.

Nada. Games, apps, this thing jumps 4c to 6c at load, then right back down to 18c or lower at idle with cool n quite enabled. I've never seen temps fluctuate so fast though. Being that they go down as fast as they go up, I'd imagine I'm safe.

The north bridge on my motherboard however, gets extremely hot while gaming.

The thermal take V is so big it's blowing a decent amount of air over the said north bridge though so adding cooling is probably pointless.

I've since gone back to 3.36ghz for lower voltage's.

240mhz NB clock @ 1.269v
2400mhz ht link (auto voltage)
801mhz mem clock (auto voltage)
3.36ghz CPU @ 1.35v Vcore (1.344 in CPU Z)

80+ fahrenheit if I go by the bios readings. The max I've seen CPU Z hit was 24c so far. I remember my XP2500+ running around 34c idle and 38c to 40c load when I first got it.

However, the 2500+ runs at about 36 to 38c idle now, and 40 to 42c at full load. I've tried resetting the heatsink to no avail on that rig. Perhaps this one will warm up on me, also.
