so did you look at the stress.txt file?

so did you look at the stress.txt file?

where do i find the stress.txt file?

anyone? suggestions?

Dude, first thing you need to do is really look at your CPU-Z window, you can see right there what the problem is!

Core speed = 803.5MHz
Multiplier =X4

You got something set wrong in your bios, or you got a bad board!
Or youve got C&Q on and its showing that in your CPU-Z window?
I'm running a AthlonII X4 620 and i can tell you that you multiplier is way wrong.
try X14 and I would just about bet that a bunch of things including Prime will run alot better

 

[smokarz]

thanks for the response, but i have absolutely no idea what you're talking about.

this is the first time i ever heard of running CPU-Z or Prime95

what is C&Q? what's X4 vs X14?

 

[Deadstick50]

Ok, AMD motherboards have a system you can activaite for the CPU called cool & quiet, i was using the common term C&Q for that. It automatically reduces your CPU speed and voltages to cut down on heat and save energy.
Since you dont know what that is I figure you didnt activate it yourself.

So if you look at the first picture you posted from CPU-ID you will see near the bottom left two areas marked core speed and multiplier.

For the cpu that is listed the core speed is way to low, and it is being caused by the second item, the multiplier setting, which is shown to be at X4 when it needs to be set to X14.

Now, the only way this can be changed is to go into the BIOS settings and correct it.
You didnt list motherboard type so I cant advise you on navigaiting thru the BIOS.
Do you know how to get into the BIOS and make changes?
Please dont be offended by my asking, I simply dont know your experience level at this point.

thanks dead,

i have the same mobo as you. Asus M4A785TD-V EVO

i see that in bios is set to 'Auto', is it better to leave CPU multiplier to Auto or select 'x14 2800'?

 

[Exzess]

x14 2800 is what you want

 

[Deadstick50]

If it was set to auto when you first looked at it I suggest you go ahead and set it manualy to X14, then when you boot into windows, run CPU-Z and post me a pic of it on here so we can be sure it set right......then all youve got left is try Prime95 again!

Good luck, Dead

 

[smokarz]

went into bios and set it to 'x14 2800'

loaded cpu-z and it's still showing 803 x4.

however, when i loaded prime95 and start running (100% load), it went to x14 2800.

as soon as i stopped prime95, it went back down to x4 803.

i guess it's the cool & quiet thing at work.

 

[Deadstick50]

My internet service is down, sorry for delay...guess youre right about cool and quiet, but how did Prime run this time?

Dead

 

[smokarz]

prime95 ran just fine. no errors at all.

 

[Deadstick50]

Thats great smokarz, good luck with it!!

Dead

 

[smokarz]

thanks dead.

after running stable for the past two weeks, i got the first 'blue screen of death' yesterday while watching a vid clip.

system shut down and rebooted, and then it ran fine again.

strange, not sure what's going on or if i would see that blue scree again. lol
