My Athlon64 might be done :(

Well my motherboard hasn't been acting right, failed postings, won't pass memtests with any RAM, won't load with certain DIMM slots full. It is just messed up in a bad way. So I sent in a RMA request to get it replaced. Which was approved today so because I have artic silver on I figured I'd run Prime95 for a little while just to soften it up to make it a little easier to slip the heatsink off.

So I leave and go watch a show while its running only to come back and see the CPU fan isnt spinning, WTF? I had my temp monitoring software running and it was reading 85C (the machine was still running and hadnt failed in Prime95 either). I hit reset, thinking wtf did I forget to plug in the fan, but then I hear it spin up full speed. So I go into the BIOS and I watched the temps dropping fast from the 80s down to the 40s.

Stupid DFI like why would it do that. Note every BIOS setting was at "optimized defaults" so I think by default it throttled the CPU to 50%. Do you guys think my CPU is toast? Or just 8 of its 9 lives gone?
 
Just try running memtest and Prime95. If there are no errors, it should be fine. If there are problems, bitch to DFI and see if they will give you a replacement. Assuming it was a mobo issue and not just user error, they should help you out.
 


If it didn't smoke and still boots it should be fine, just missing one of 9 lives... Puzzling what shut off the fan though... ? I think I would have to buy a new fan just to make myself feel better about if it will stop again.

I'll run it when the new replacement board gets here.

It aint going back into that board again. I played with a little more and watched and for some reason the CPU fan again just stopped... then it started twitching like it was trying to move, I hit reset & it spun up again...then in BIOS it spun down again and stopped after maybe 10 seconds of spinning..

I don't know...

I know this story sounds like I could be an idiot, I always think that it is user error when I hear stories like this... Unless you can think of some setting I hit some how that does this I have no clue how I could have caused this, also I noticed the left most red diagnostic LED stayed on when I was just messing with it.

Good idea about the fan, think I might order up a XP-120 or something.
Ohh my poor poor San Diego 🙁

 
Are you using the stock cooling? Maybe you could upgrade the heatsink (especially if you plan to OC that bad boy). I would recommend the xp-90 over the 120. It is much cheaper, works on most boards (many don't support the xp-120), and performs almost the same with a good fan...

Umm, do the words, "Cool and Quiet" mean anything to you?? It's SUPPOSED to do that!
The replacement board will do it too!

It automatically spins down the CPU fan and when it gets hot, it spins it back up. I disabled it on any PC I worked on with it.

I had the crap scared out of me when I built a new PC for a friend due to this "feature". I hadn't heard of it, and didn't read the manual about it. I had just finished loading all kinds of stuff on it, and it was working great, and I went out into the kitchen to get something to eat and I ended up watching something on the news for 15 minutes or so.AS I come down the hall, I hear some kind of alarm going off and the CPU fan is twitching and then spins up and the temp went down to 30 degrees and then the fan starts slowing down again. I watched it do it again, then got out the manual and disabled it. I think cycling the CPU temp like that is a really dumb idea. It's asking for cracked solder joints, not to mention stressing the CPU thermally.
 
Cool and quiet is a very messy situation especially with older boards.
For one thing, it may not function correctly at all with 3 or more dimm's.
The OP said he has a NF2 which I dont believe supports C&Q at all.
C&Q is also supposed to lower CPU voltage (undervolt) which should lower temperature considerable, not raise it. However some mobo bios do not allow this.

I think the fan bearing may be freezing, or the PSU cant supply enough power to board - Try running the fan with a PSU 12V molex and a fan adapter would be a good test, also try another fan.
Vari speed fan can also be a problem.
 
The board was a DFI NF4
Cool & Quiet is disabled by default (and I did not turn it on)

Actually now that you mention it, I wonder why no alarm went off went...
 
Thats sad,

My 2 1/2 year old 3400+ s754 shuts off by it self when it gets to hot.

EX.

My fan has died twice, or I forgot to plug it back in after re-wiring, etc,

It shut off by it self.

I kept trying to boot but it kept shutting on its own.

Then I realized the fan was unpluged.

Why wouldnt they add that feature inthe new s939 cores?

Or is it my motherboard
 
Sure sounds like cool and quiet, right down to the "twitching" fan. I remember how my stomach turned over when I saw it sitting there. I had the ASUS monitor utility going and it was telling me something wasn't right. Just as I was about to turn it off and hope it wasn't cooked, the fan spun up and went down to the normal idle temp and then it did the same thing again.
That was the only problem I had on that PC, it went together like clockwork and the only problem it's had was when IE got hijacked, and hijacked good. Format time.
 
Cool and quite will never "turn off" the fan... It merely will clock down the CPU and lower the voltage while idling, which lets it cool off and the mobo can spin down the fan. Are you connecting the fan through the motherboard? Perhaps try to set a threshold in the bios (70C or so) for the PC to turn off...

Edit: If cool and Quite is kicking in while he is running Prime 95, his CPU is seriously messed up. It doesn't cycle temps like you describe. Perhaps you are thinking of thermal throttling on prescotts?
 
Don't these chips have an automatic fail safe? When the temps get to high, the whole system shuts off. If you are not failing prime95 at 85c, I would think your mobo temps are not accurate.
 
Well it was still running Prime95, although I wish it would have failed so it had stopped running it. It probably didnt fail because the CPU was throttled back 50%. I think if I remember right the DFI board throttles the CPU to 50% by default. So the CPU was probably "only" running at 1100Mhz.

I will find out in a few days if the CPU is dead when the replacement board gets here. But I wouldnt be surprised if it done, I read the critical temp for the Athlon64s is 70C. I'm going to go research some new coolers now 🙂
 
I think all u guys are just looking at the worst case scenario without first checking out the BASICS...

Why NOT look at the easiest solution and make sure the FAN is not faulty... coz that relle looks like whats causing it...

This could really be the cause. I have thought of it, hence why I am going to look for some new cooling.

The motherboard was still faulty though, it would not load up properly using the yellow DIMM slots, failed Memtests with any memory and sometimes was failing to post. This is why I was running Prime95, just to soften the artic silver to easily remove the heatsink. I already had my RMA number for the board to go back for a replacement.
