Hey fellas. Built a new rig few weeks ago...2600k msi p67-gd65. I have drivers, bios etc all updated and just decided for a nice manual overclock to 4.2 via bios...Prime 95 stable after 12 hours, intel burn test, lin pack etc. temps don't get passed 62c with a h70.

anway, I left the cpu/dram voltages on auto as i like to utilize c1/speedstep when idle....wierd thing is I noticed playing mafia 2 this morning in windowed mode that cpu-z will show the cpu overclock bouncing back and forth between the 4.2 overclock and 1.6 ghz....

During prime/lin pack, it stays at the full overclock...is this normal for the cpu to downclock during a game...I thought games would constitute as full load needed by the cpu...can anyone with a 2600k overclocked confirm this during games? thanks
 
Games are not anywhere near the load that Prime95 applies. So it is normal.
 
If you aren't experiencing any performance issues, I would say it's normal.
 
Turn your resolution way down which will ease up on your video card and increase load on the cpu, I bet you see the cpu clocked higher more often.
 
Better yet,
turn OFF the power saving modes: EIST, C1E, C3/C6. Problem solved.

There are TONS Of games out there that won't even load a GPU at full 3D speeds, because the drivers can't detect a load, since the games barely stress the GPU more than windows does (Soldier Front is an example).

That would be solving a problem that doesn't exist in the first place. If the game needed more CPU power, the CPU wouldn't be dropping its frequency altogether.

Yeah I was just giving a quick example of how he could see different loads on the cpu affect the clock rate.
 
well...I don't know what to say but 12 hours prime95, few hours linpak/occt....no issues...play mafia 2 for 15 min....infinite loop crash...sound screeching....razer kb and mouse lose power....I revert to default in bios...run everything at stock and ....no issues....I think overclocking is great and im pissed becuase i bought this chip to overclock bu I built a gaming rig and I want to game w/o crashes...I left the vcore on auto for a 4.2 ghz overclock...u guys think if I manually set it to say 1.3, that could possibly stop the crashes in games? wierd becuase on auto at 4.2, I can run prime for over 12 hours w/o a hiccup...
 
latest bios addresses razor mouse issues I believe...have you tried just using the oc button on the mb... if that works for you then its just a question of tweaking your oc.

ty for the reply..ill check msi's website...i have 1.9..thought that was the latest...ya i used oc genie and didnt have any probs but id like to overclock manually rather then having it done via software...but i guess oc genie is built into the bios though?
 
CPU-Z is designed for consistent validation purposes and doesn't tell you the whole story when your CPU is lightly loaded and individual threads are bouncing around from one C State to the next. The programmer of CPU-Z acknowledges this issue.

Of course I admit that CPU-Z is not accurate anymore at idle on latest Intel generations, that is why TMonitor was developped.

Give ThrottleStop a try and you can watch the average multiplier for all 8 threads in real time. It follows the Intel recommended monitoring method for Core i processors as outlined in their November 2008 Turbo White Paper.
