I built my PC a few months ago. I know that it functions properly and noted that the processor was clocked correctly but recently I have noticed some instances of laggy performance, and I thought it is odd because I have state-of-the-art hardware.

After looking at several performance monitors (Windows Performance Monitor, Task Manager, HWMonitor), I found that the Intel Xeon E3 1246 V3 refuses to run any frequency over 800MHz (minimum frequency). I hunted around in the BIOS for a while, checked drivers, etc. and it appears that nothing should be wrong. MSI Gaming 5 motherboard. Help?

I couldn't help but notice that I've been gaming on this processor this whole time and still haven't had a problem. They don't lie when they tell you gaming isn't CPU-bound.

Give it something to do. Its going to sit there at 800Mhz when there is nothing to do.

Download HWinfo, install and run it. Then play a game for a bit. When you come back, it will tell you what the cores managed to get up to, same for temps too. CPU, GPU, everything.

It tracks current, lowest, and highest...

I also left out (but it is in the screenshot link) that I set a torture test loose on Prime 95. It's been running at 100% utilization stuck at the lowest frequency.

I'm using an EVGA G2 650W PSU on a single-graphics card setup, so power is definitely not the issue. I can't find the speed-step or turbo-boost settings in the BIOS (Click BIOS 4 V1.11). The CPU Stepping in the specs page is 3, and the frequency and ratio check out at 3.5GHz and 35. The base clock is 100, and the core count is 4 with HT on. Seems like it should be fine.

I looked at that other thread you mentioned, Solandri, and I could have sworn I remember seeing settings like core count, but I've not been able to find them now. Any idea where to get those?

I ran the Intel Diagnostic and stress test from their website and my CPU passed with flying colors! 66c under threshold at the end!!! But watching CPUz the clock NEVER went up even under a sustained load of 100%!

That is from the link someone posted earlier... I think I would try that and see what it tells you.

I would also like you to download CPU-Z and for you to show me the results of that screen shot when it un running something in the background.
