Saved "Stable" Bios Setting became unstable-I had to do a cl

[BuddTX]

I had something interesting happen to me this weekend.

 

I had some very stable BIOS settings at 2810 (281x10), but wanted to see if I could go faster. I had saved these "ultra stable" Bios settings a month or so ago, in the BIOS, because I did not want to loose this setting.

 

I played with all kinds of settings, but no matter what I did, Prime95 would fail on Core 1 (Core 0 never gave me an error!)

 

So I gave up, and wanted to go back to my saved, very stable, 2810 settings, tha I have saved in my BIOS.

 

So I just did a LOAD from the BIOS, and re-booted my computer.

 

Then, just for fun, I started Prime95 again, and I started getting errors immediately, on Core 1, just like I was getting when I was trying the higher clock speeds.

 

I re-booted, and again, errors at once on Core 1, with the supposedly "VERY STABLE", 2810 BIOS settings

 

I decided to turn off the PC, and let it sit for a while, (like 30 minutes or so). When I turned it back on, again, Errors again on Prime95 immediately on Core 1.

 

Now I know this setting was rock solid stable before, so in desperation, I decided to open up the case, and clear the CMOS with the jumper.

 

Started it up, Re-Loaded the pre-saved 2810 BIOS settings already stored in the BIOS, and Prime95 ran fine for hours on both cores.

 

Wierd huh?

 

Glad it is fixed, maybe this post will help someone else that might be having the same problem.

BuddTX it's normal for one Core to keep going while the other fails,.. If one fails it doesn't mean the other Core is stable, just means they can't be both stable.

I think he missed your point. ;p

Maybe my point got lost in the details!

 

My point was, that my KNOWN STABLE SAVED BIOS settings were not stable, even though they were stable before, and I tried to "restore" the settings more than once.

 

It took a CMOS clear, (Something that should not be necessary) then one more re-load of the known bios settings, to get my system stable again.

At times it is necessary. If Prime was continually failing then the system was not stable. The bios could have been slightly corrupted. Using the saved settings won't always fix the corruption where as a coms clear will.

 

When i experience unexplained stability issues clearing the cmos and reloading the settings is one of the first things I do.

Budd, I am very happy you posted about your experience, it has helped me figure something out...

 

So I just got this current opty a few days ago, got it running 300x10 @ 1.45v perfectly stable. I saved the settings in CMOS, and of course have been tweaking the hell out of it to see what she can do. Today, I decided to reload the know stable settings & prime was no longer stable... So I did some more tweaking, but I couldn't get it stable like it was before...

 

I read your post a few hours ago, & thought it was worth a try, so I clear CMOS, reload said known stable settings, and now Prime is chugging away happily :nod:

 

Thanks

AWESOME! You are Welcome! I am Jealous that you were able to get to 3G. My More Expensive 4800+ chip can only go to 2810!

I am pretty stoked that I Hit 3GHz and on such low volts too

 

I haven't seen many 4800+ get to 3GHz... My other opty 170 I got to 2.9 on 1.572, but I didn't run it like that everyday, I ran it at 2.85 on 1.5v, but I think I killed the OC with too many volts Thats what inspired me to buy a new opty... And boy did I get a sweet chip :cool:

 

Something else to consider is that I have this puppy cooled with water & that has made a big difference...

 

Thanks again
