Why is my CPU dropping down to 3.6Ghz?

So I tried over clocking my system using two different tutorials and when I look at my computer properties it says 4.4ghz. When I open up "Core Temp" it first says 4.4, then drops down to 3.6ghz. I run prime95 and the max temp I have seen is 55*c

Why isn't it staying at 4.4Ghz?


System:
Cooler Master 120mm Liquid cooler
3570K
Gigabyte ga-z77x-d3h

It looks like EasyTune 6 was throttleing the speed after the CPU hit low 52*c. I bumped it up to 75* and I am running at mid 60*c @ 4.5Ghz w/ Prime95 on

do not use easy tune!!!

go into the bios and overclock....

When I uninstalled EasyTune it looks like something is throttling capping the speed again :(

go into safe mode, and make sure you got it all(the easytune.) maybe try a ccleaner.
then, restart go into your bios, default that. restart windows make sure everything is ok. the begin your oc anew. from the bios!

So I managed to get it to 4.4Ghz some how. I disabled Turbo, set the multiplier manually to 44 and vcore to 1.23. I ran prime 95 and had mid 60*c for a couple hours. I played a game for a few hours and noticed an improvement in FPS. After that I changed the vcore to 1.25 and tried 45 and 46 on the multiplier. It looks like I ran into the multiplier does not take effect as it was showing 4.4ghz when I started tests again.

Do I need to increase the voltage more and is there a document w/ voltage ranges to multipliers? After running prime95 all night the max core got up to about 74* and it looks like the average was around mind 60's still. I am still running prime95 and will check it after work. I don't see any WHEA errors in the log files. From what I have read going over 1.3 voltage range can be bad.

Please correct me if I am wrong:
1) Multiplier increases the speed by 100mhz
2) VCore increases power to the CPU, if you are having stability issues, while at the same time adding heat
3) You cooler helps reduce the heat supplied by the OC and the increased voltage, though there is a limit of how much heat can be drawn away as well as IB chip limitations that can vary from chip to chip.

1) yes

2) yes

3) yes, the hsf should have a thermal dissipation rating.

I read staying under the 1.3 is a good idea. as a reference im at 4.7ghz, 1.296v, I get to 90c when priming, highest i see is 65c while gaming or anything.

I used thios guide:

might help ya.

Thanks for the info, what cooler are you using? I would at least like to get to 4.5, maybe even 4.7ghz, if my cpu is one of the good ones.

Also I have read that over 1.3v is not good as well. Is this because of heat or because of something else?

Strange, according to that doc from intel it says the following:



Does this mean that you should never exceed 1.52v and that 1.3-1.45v is okay? If you have good cooling?

Also I have a gigabyte ga-z77x-d3h and not an asus. Though I can use this as reference.

Yeah i saw that as well. guess if you have the cooling, you can go higher.

I am using a 212 evo.

Yeah just use as a reference. may want to google and see if there is a guide more suited to your board.

good luck!

I found the problem to my issue. For some reason it looks like I have to completely shut down the system for the changes to take effect. I have a stable 4.4Ghz setup, though I am still working on getting it up to 4.6Ghz. Did you do anything else other than vcore and multiplier? I started a new thread about this, separate topic as this one has been pretty much answered. Thanks for your help!
