Sandy Bridge Overclocking - IS CPU-z lying to me?

post #1 of 8
Thread Starter 
Ok, I have the multi set to 41 and the CPU Freq set to 100.

In the BIOS it recognises this and says im set for 4.1GHz. But, CPU-z says the multi is at 38 and thus the speed is 3.8GHz.

Is CPU-Z playing up or has my OC not taken?

Oh yes. One of the first things I do!

Everest still doesn't have SB support, unless I'm missing an update?

Google "cpu-z beta" and download the latest version (1.56.3). I've spent several hours after buying my new rig on troubleshooting the issue with fsb frequency and cpu clock (cpu-z had some very strange readings), only to discover that I've been using a 1.56 instead of 1.56.3 - the bloody program been lying to me all along.

Is it possibly because I'm not using a k version of the 2500?

Also, Windows reports the CPU as being 33x105Mhz.

Also, using 38x105=4000MHz works and shows correctly in CPU-z.

I have read on multple websites that the k version does not support changing multiplier.
Dont take my word for it though.

What? The K versions are the ONLY ones that have an unlocked multiplier.
