CPUZ Bus does not equal BIOS Bus???

post #1 of 7
Thread Starter 
I'm trying to OC my 3800+ Venice core via the Bus in 5mhz increments or so, but for some reason CPU-Z maxes the bus reading at 218.2mhz and my settings in BIOS is near 230-240. My CPU is running hotter as it should be with more voltage/faster Bus, but CPU-Z reflects nothing.

Stability is similar in a <210 or >220 bus.

Also the voltage readings are wrong i have it at 1.55 and CPU-Z/NVIDIA monitor telling me contrasting data its 1.4 in nvidia and 1.575 in CPU-Z

Cooldude, after making the changes in the BIOS are you "Saving" them before exiting? I know some BIOS require this before you exist a certain sub-menu.
In regards to CPU-Z, anything that is higher then 1.4volts in the BIOS will read incorrectly in CPU-Z. I believe this is some type of bug in the application.

Good luck

I know the values are changing because they are stickin in the BIOS on reboot.

CPUz reads the voltage right on the new 45nm processors. but yes make sure the settings save. and also what do you mean its different. like by 4 mhz if so that is normal.

Killa, that would be nice if his 3800+ was a 45nm processor but it's not

Cooldude, make sure Cool'n'Qiuet is disabled. If your processor multiplier is set to "Auto" then it might be causing this problem. Manually set the multiplier and see if that helps.

Good luck

Firstly a lesson on voltage. That is a voltae drop your experiencing and its normal.

Your voltage will not show what you have in BIOS, and thats just the way it is. Its the v drop and idle PC to know what your voltage is. As you play games and stuff the voltage goes down, cuz of v drop.

Also try to see if theres a option for TM function disabled and CE1 diabled. As that will reduce your readings, although in BIOS it says what it is. Once you disabled these you should have a perfect match of BIOS. If you take FSB to 230 it should show as 230. GL this is not a problem, just option in BIOS that doesn't give proper readings... see how it goes,,

Tweakboy, I was under the impression that vdroop was prominent in only Intel motherboards?

Cooldude, have you verified the voltage readings with other applications?
