What to do when... - Page 2

post #11 of 22
I was able to run 4.0 GHz at 1.35-ishV that was 8 hours Prime stable when I first got it. Someone told me the 1.3625V thing was a myth, so I was able to get to 4.3GHz at 1.39V, pretty stable. However, when I tried to go higher, the PC wouldn't POST. After that, I had to put 1.35V to get 3.6GHz stable enough to even use Firefox more than an hour or so. I'm not 100% positive it was because of the voltage increase, but it seems like the most likely culprit.

I'm currently in the process of trying to break through the 3.6GHz wall right now. I have been doing it the old-school way, 10MHz FSB at a time, and I'm trying to see if I can return this chip to its previous glory.

I guarantee you that chip has not degradaded a single bit. There's some other reason I know of people who have been using 1.5V since January of this year and have not degraded at all as well. but again, I do not recommedn that at all .

randomly, there weren't any bios upgrades, cpu/heatsink lappings, cooler change outs, etc. etc. etc. between those times, were there?

you prolly played with another setting like FSB-t or PLL or NB-v something like that.

I say ignore prime results and use normally. If you don't run into any issues, then for all intents and purposes, it's stable. Besides, you could downclock it to 4GHz, and it might not be stable after 20 hours of prime. You could go even lower, etc., etc., etc. I say if you haven't encountered any problems with normal use, just go with it.

I don't use any stability-testing software. I just use my computer. If it crashes, I up the CPU volts by a notch. Depending on the type of shutdown, I can tell what it is. Blue Screen, probably memory (though not always). Black screen and then the BIOS splash, usually CPU voltage. Whateva whateva, yo.

You guys really should test stability. One too many memory/cpu crashes and your windows installation will be bunk. Reformat time!

Not really. I mean, what's considered stable? 8 hours on prime95? 16h? Because someone arbitrarily said so? Just 'cause a rig passed prime for 8 or even 24 hours without an error does not mean it's stable. It gives peace of mind, but doesn't mean anything other than your rig can pass 8 hours of prime. There are normal-situation operations where a rig can be more susceptible to errors than in stress-testing, so just by running prime or orthos doesn't mean a rig is even stable [edit--(and conversely, there are many situations where a rig can fail prime after 8 hours but never encounter any problems during regular use like gaming or web browsing. it's just the chances.../edit]

Also, how will an unstable overclock do anything to mess up a windows installation (other than maybe a registry error)? Besides, there's a repair install option--no need to reformat every time...

try upping the voltage a tiny bit, but im stable on 4ghz at 1.328v, 1.328 and 1.36 is a big difference for the same revision

not really....some unstable memory might do it, but not cpu.
