Noticed some weird fluctuation

post #1 of 8
Thread Starter 
I have an i5 2500k set at 5.0GHz. I loaded up a Prime95 blend test and noticed, for the first time, a small fluctuation in my clock speeds.

It goes from 4999.9MHz to 5001.1Mhz. Also, voltage goes from 1.416v to 1.424v.

The voltage has done that since I moved up the multiplier, but I've never seen the clock speed fluctuate before.

Also, may be a non-issue, but I have a script on mIRC that shows my system specs:

moo: os: Microsoft Windows 7 Ultimate - Service Pack 1 (6.1.7601) up: 2mins 10secs cpu: Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz (x64) at 3301MHz (100% Load) gfx: NVIDIA GeForce GTX 560 Ti 1.00GB res: 1600x900 32bit 59Hz ram: 2860/8174.7MB (34.98%) [|||-------] hdd: C:\\ 40.99GB/99.9GB Z:\\ 802.42GB/831.51GB net: Realtek PCIe GBE Family Controller - 100MB/s 2.81MB In 460.4KB Out

But it doesn't show my clock speeds. A friend of mine uses the same script, but his clock speeds show up. Could this be a client issue, as he uses IRCn, not mIRC?

I know I'm actually running at that clock because my FPS improved quite a bit by each multiplier change.

I don't know about that script thing, but I do know that these fluctuations are normal.

That's good to know. Waiting on my H100 so I can run a 12hr prime test to check for stability. Depending on temps, I may try to achieve a higher clock.

Completely normal, I had these fluctuations with my i7 860 awhile back and I have it now with my 2600K.

Rest easy my friend.
