What is considered "stable"

[siranthony]

Hi all,
I have my 2.4c at 3.0 250FSB. I was able to go higher. I think I was able to do 266 and higher with 1.6v. I was able to run sandra at these speeds. I get errors in prime95 at anything abouve 250FSB. Incresing the voltage alows me to go faster but doesn't fix the errors in prime95. Will it be acceptable to have errors in prime95 if everything else seems to be working ok? Or would I have a system that would crash randomly or basically unstable?

These specs are here so I don't have to repeat them. P4 2.4c @ 3.0 ASUS P4P800 dx Geil pc4000 2.5,3,3,6 250FSB 1:1 Radeon 9500 non-pro 2 Maxtor 60gig 7200rpm 8mb cach in raid 0 SB Audigy 2

In order to be sure your cpu doesnt mess up the registry or crash randomly, make sure it can do a few hours of prime95 or more.

If its failing prime then at some point it will let you down, probably when you update a driver or install software or burn a dvd, some information may get corrupted.

You'r memory might be causing the prime95 errors, not the cpu! Or the chipset could be over heating. If throwing more volts at the cpu doesnt solve the prime errors, back off the memory timings, try a better cooler on the northbridge or processor or run the risk of it messing up later on.

I could easily run my barton at 2500mhz on 1.85v and run everything fine except prime, but I would rather keep it 100% stable at 2400mhz. And thats a nice overclock you have there anyway, should keep you happy for ages!

Hi,
Thanks. I'm happy with 3.0. But I want more muahaha. I got the nerve to put 1.7 volts to the CPU last night. Lookes to be stable now at 266 FSB 3.2 ghz. Although I have only run prime 95 for 10 miniutes so far. But my memory is now the problem. Seems it is not very overclockable past 250 FSB. I went as low as 260 but still got a couple of errors in memtest. It won't run at all at cass 3. So that limits the O/C potential. I wish my MB would let me up the mem voltage past 2.85. Running at 266 5:4 gives me about the same memory score in sandra as 250 1:1. But I would rather run 1:1. I might look into even faster ram. If I can't run at least 3.2 1:1 then I don't think it's worth the risk of 1.7 vcore. My temps at 1.7v are 40 idle 48 load. I have heard that anything over 1.65 can be dangerous. Anyone know if 1.7 volts poses a large risk of significantly reducing CPU life?

Thanks

Anything over 1.9 is dangerous, 1.7 is nothing, as long as temps are below 50C which is what i like to keep it under.

250 seems to be the best it will get. You may be able to runs stuff fine at higher speeds but if prime95 tanks out, you will enounter fed-up registry issues and missing software. Nothing worse when that blasted ntoskrnl goes byebye on you or your system32 gets hosed.

Welp. I will have to wait to tweek my comp some more. I flashed the bios with the ASUS update util and my comp is now dead. I suppose this will be a good experience. This never happened to me before. I guess it had to happen sometime.
