Sweet! Keep us updated on your progress.

Two of core temps keep jumping around. They go from 60 down to 54 in an instant. Then they go back up after 10-15 seconds. Anyone know why? I use speedfan. Could the heatsink be loose?

5 degrees is usually the standard fluctuation between my cores depending on what I'm doing.

From what I can tell, native affinity starts with the first core and continues from there.

Depends on what you're doing really, and what kind of load you have.

If the CPU is loaded, it can easily jump 5-10, even 15 degrees between loading and unloading, practically instantly (relative to speedfan).

Even without load, it isn't terribly unsual behavior. The hotter you get, the more fluctuation you will see.

I'm doing P95 small FFT's. Well I suppose its ok as long as it doesn't jump up in temp

Hello. I registered to post in this thread

My tale of woe!

All the important and not-so-important system specs should show in my sig.

I got this board for Christmas and things were good. Through some testing and trials I overclocked it to 7x460 / 3.22ghz up from 7x266 / 1.86ghz. That was pretty sweet. Yeah, it was.

Anyway this morning I started the thing up and all the BIOS settings had reverted to their defaults. Oh crap. I loaded the CMOS profile of my OC'd settings and rebooted, and right before the BIOS reported the memory speed it rebooted itself. Fiddling with every setting individually and rebooting like 50 times lead me to discover that the only part that actually causes the reboot is when you unlock the FSB. Even if I don't change it from the default of 266, if I have it unlocked the system reboots. Even if I underclock it reboots.

What. The. Hell.

At that point it was time to get my hands dirty. Opened the case up, unplugged the battery, shorted the clear CMOS jumper, unplugged and reseated every card and cable (except the CPU), left the battery out and the power unplugged for an hour. Should be enough to fully clear everything right? Well it didn't make any difference. Here I am at stock speed asking for help. I've read several threads on different forums about people having a similar problem but they never seem to come back and say 'oh yeah I fixed it by doing <foo>'.

So let's get to work Please help. I want my megahurtz back.

Been running P95 for 90 minutes @ 3.4ghz and temps have hit a max of 61C. I know after 90 minutes I can't consider the OC stable yet but can I consider it temperature safe? I can't see how I could ever be maxing the CPU for 90 minutes. With intensive graphic games its mainly the video card that gets taxed not the CPU right?

Sorry about all the noob questions the last couple of days. Thanks for the patience. My first OC

I think I remember that 90c is the unsafe limit. You don't want to approach it, and most CPU will shut down at that temp.

61c is definitely safe.

I know for my CPU 71C is the limit. Suppose I should of mentioned. Thats something I like to do. Leave out important details

Its been 110 minutes now and still at 61C. The room is 72 F.

Hey Passive Fist. Maybe this will help your problem. I found this post farther back in the thread:

To all of the guys having the problem of your overclock settings going back to default on re-boot or start-up,

I posted this 10 or 12 pages back, but it probably got lost in the mix by now. That happens when these threads get this long and I noticed this issue is still happening to others again. Anyways, I was having the same problem. I'd OC. I test with Orthos, OCCT or Prime95 all night long and pass just fine. Then I'd power the system up the very next day and everything would go back to default again, every single time. It was driving me crazy. I did some Googling and found out that this was happening to others as well. The fix was a setting in the BIOS. Under the "Halt On" section, set it to "NO Errors". This completely fixed my problem and it has never done it since. It's been almost a month now and it's still working just fine. From what I was reading is that the system sees that the CPU is not running at the correct/specified speed and it's thinks that that is an error, so it stops the booting process and resets everything. I don't know if it will work for all of you, but it worked for me.

Also, my board was shipped with the F3 BIOS. I flashed to the F6 version and the problem still persisted until I changed that one setting, so I'm going to assume that it's not a BIOS version problem for any of you.
