Can you live with that!!

My OC P3 1.1@1.3 is stable at everything and all stessing prog. except for prime95....I keep getting problems with it..

Well i do not know...I am not the OC pro here to know if this is fine or not....Any feedback on this is apprec.

[BigRed]

need more info.
what vcore are you running at? what motherboard do you have? what memory do you have? what power supply do you have?

Here you go

1.95V
soltek with VIA APo. PRO 133A
256 RAM PC133 CAS 2
ATX power

what fsb are you at?
you might have just gotten a lemon and it might not oc :(

I always use Prime95 as a stability test. If you have errors, it is not 100% stable. At what speed do you not have errors?

[voodoo 1976]

Have managed to reach 118 FSB...But also get problem only on prime95 at 112FSB and up...

I really can not get it...Everything runs great even all my 3D games that kick the crap out of any sytem...And I know that prime95 is verry correct...

[oldfart]

Another test I use is Serious Sam. If there is the slightest problem, it will crash. Unless I can run Prime95 and SS with NO errors, it's not a stable system.

[voodoo 1976]

Thank you man....Have not tried this game....
Will install it today and see!!

[Yodums]

Good job, strive for more!

Keep burning in it'll help.

[oldfart]

I forgot to mention....Its a heck of a lot more fun than Prime95!!

[voodoo 1976]

:D :D :D
I will burn it as much as I can....:D
hopefully this P3 will be the PRO i thought it was before buying it

[Yodums]

CPUBurn and Prime is mainly the most CPU stress tester avaliable. Max Payne seem to be a good one too where cpu, memory and graphics play a big part towards the game.

Prime95 is also a good test of memory stability. It shows my ram will run 145 FSB 2-2-2 5/7, and will error @ 146 FSB 2-2-2 5/7.

voodoo, I was finally able to drop the voltage on my 1.1 from 1.95 to default about a month ago. It took a few months for it to be happy there, but it's zooming along at 100% load w/ SETI. Used to be way unstable at first. It's been a while since I've had any trouble out of it.

[deez]

VOODOO...I burned in for a week with my chip at 66Mhz and the voltage at 1.95 but I also have a nice large case with good airflow and my PCI devices can take the high FSB

Your instability could be from a number of things including but not limited to : improper CPU cooling : improper case cooling : improper bios settings : PCI devices cannot take the high FSB

if you have not read the beginners guides and most of the articles on www.overclockers.com then I recommend doing so. There is a wealth of knowledge to be gained there and from other sources as well such as your hardware manufacturers websites

[voodoo 1976]

Thank you all for the feedback....

Well I am sure that the instability is from the processor only since prime95 tests mainly the processor and not PCI devices(mentioned in the readme file)....

I use 3D gaming much with no problems..and as you know games stress HDs and sound cards and AGP bus also...so this makes me very sure that it is the processor....I even stessed my all devices using SANDRA and passed with no problem....

My RAM is PC133 so it is working on less FSB that it is supposed to...And RAM settings are all set to low settings just to make sure that RAM will not be a problem...

This P3 is really strange....It can run prime95 on FSB of 109 with the default V without any problem at all....If I try 112 FSB then prime95 will not be happy at all ...I have tried to increase V till I reached 0.2 increase with no success....

The temp. of processor will not go more than 37 on full load...
and case temp is about 23 ....I have 2 powerful fans in the case ..

I think that all who reached the 1.3 using this processor have unstable system...

What also makes things more diffcult that I read on some overclocking resources that burning is a crap....is does not work....people think that it works but they are incorrect...

I dont know maybe they are incorrect and maybe they are not!!

[oldfart]

Prime95 is Da Bomb for stability testing. I use it on any overclock I setup. It will find a problem that nothing else does, and it will find it fast. Unless your system passes this test, you cant be sure it's stable. You are correct that it only tests CPU/Mem stability. That is fine since that is what you need as a stable base before you test anything else.

[deez]

Overclocking is not a science every chip is different and some overclock much better than others while some barely overclock at all. You could have the exact setup as somebody else and get completely different results

Thats what makes it fun you never know what your gonna get

[SephirothXavior]

I currently have my celly 1ghz @ 1.333ghz and its still on default vcore. At first i couldnt run at this speed because of who know what. but now i can run prime95 and loop 3dmark 2000 demo for six hours so its pretty dang stable. I dont know what made it work but im not complaining. or maybe its because i have disabled everything and can get 97% free resources. who knows.

My 1.1s are stable at 1333 with a 1.9 Vcore on a VP6. This is with watercooling. Using Glaciators, 1309 with 1.9 Vcore. You may want to work on your cooling. BTW, since my board is a dually, I run Prime and CPUBurn at the same time for stability testing. Been going strong since I installed the waterblocks last Saturday.

I used to think this, too. Then I played with a couple of chips that "decided" they'd go higher after a while. Screwy, but it does seem to work.

I'm sure some of you remember my 1100e 131FSB@1.95v right out of the box! Well now a days I can't even hit 130fsb & 129 is now unstable. With a couple months now of burn-in I actually lost 2-3MHz on the fsb. What I did gain however is much lower voltages (= lower temps). This pup will boot at 100fsb at only 1.35V. Even overclocked to 117fsb I only need 1.6v =.15 less than default, 125fsb@1.8v.

I went through a whole bunch of Birds last year. All of them but one gained the ability to overclock further with burn in. The one dog AXIA 1333 would do 1575 MHz out of the box. It started loosing speed within a week. Now it will barely run at the stock speed. FWIW it has a very convex core so cooling is a problem. It is such a dog, I never bothered to lap it flat. Besides, how do you lap such a small surface when it starts out convex?

[deez]

radadman...thats strange...maybe your CPU wasn't 100% stable initially. Mine wont boot at all below default vcore and I cant push it higher b/c I dont wanna burn out my PCI or HDD ....no 1/4 divisor before 133 but it will boot into the 1390's

[Crash893]

there is a new version of prime95 out that has better slightly more lax error detecting


it also has a benchmark tool now

im not sure if the error detection requirements are good or bad for us but just thought i would throw them out
