Prime 95

post #1 of 9
Thread Starter 
I've had problems with raising the voltage on my cpu, for some reason my mobo wont allow it to go past 1.4. So, I overclocked my cpu from 2.2ghz to 2.49. It runs stable on 2.47 on prime 95 for hours but it fails at an overclock of 2.49. Now this is only prime95 test, other than that my comp boots up, it runs stable, i can play games, etc... Now my question is, even though the voltage is low at 1.4 but the overclock at 2.49 failed the prime95 test after 10 minutes, will this in any way ruin my cpu? Will it damage my cpu or any parts of my computer if my overclock failed the prime 95 test but my computer is still stable and i continue to let the overclock stay at 2.49?

I'm pretty sure it wont cause any damage to the CPU its self. However it may cause problems in certain applications and may cause random reboots/crashes.
The few extra MHZ aren't worth it and wont give you a very high performance increase, stick with the highest it will pass P95 at unless you like to live life on the edge.

Just to clarify what was said above ...

The things that damage your CPU during overclocks are high temps and high voltages.

If your mobo is only allowing 1.4v [ which isn't alot to be honest ] to pass to your CPU then its not going to be damaged.

As has already been stated, the only issue you are going to have runing 2.94GHz at 1.4v is during intensive applications your computer may not receive enough power to keep it stable and either crash or shutdown completly.

oh ok, i see now. Well i dunno wats wrong with my motherboard, its not that it only allows 1.4 volts, even when i set it to 1.5, the cpuz and speed fan only reads it as 1.4 so there is something wrong with it. I cant flash my bios anymore becasue when installing the bios tool in windows it says motherboard not found or something like that... And then when i try to restart it and press alt f2 simutaneously it just shuts the computer down and wont let it start again until i turn off the power button and turn it back on. I dont know wats up with this mobo, i've flashed the bios before using both methods but now i cant even do any. There is one more method and that is to do it from dos, meaning i have to be in dos and type in some words to do it off the floppy disk but the only problem is i dont know how to get into dos. I cant do it in dos prompt in windows, i have to actually be in dos and i dont think there is a way of getting into dos in windows xp pro so i'm stuck.

In bios, turn off any thermal throttling, CoolnQuiet, and PowerNOW.

Did you have any problems before flashing to your newRev BIOS ? If not, just flash back to the older preinstalled version.

As for entering DOS, this is simple to do, all you require is a formatted 1.44MB 3.5in Floppy Disk.

Go to:

My Computer > Format Floppy Disk [ select "Make bootable floppy" from the menu at the bottom of the format window ] > Start

Once that has completed, shutdown your PC. Insert the floppy disk and reboot. As long as your Boot device is set to read from the FDD first the bootable floppy will take hold and DOS will load.

You really want your processor to be prime stable. If it's not, its creating errors here and there, and even though you can do everything else fine, in time it is possible that those errors could lead to HD corruption.
I would run it prime stable just to be safe.

thanks for the info guys, i'll try the bootable floppy disk, oh and as for the bios question no i didnt have any problems before i flashed this certain bios. I cant reflash again, thats the problem there are no methods that will allow me to go past a certain stage. So my last choice is the dos mode, wish me luck
