Underclocking!

[Mr Moopsy]

Today I was bored and decided, I wanted lower clocks, voltages, and temps.

I wanted to do something new.
Normally my 3930k runs 4.5ghz 1.355v 24/7(whenever it is on) and at 100% load via intel burn test gets 70c
(I need to not be lazy and replace my bad thermal paste, to make things worse I already have some good paste sitting around)

So, I made some tweaks.
Now I am at 1.5ghz at 1.3v 90% of the time
However when under 100% load goes to 4.2ghz still 1.3v and reaches temps of 55c



Ram is at 1680mhz

I plan to lower the clock just a little more at idle, maybe be 1ghz. see how 1.2something volts works out.

Also the bus speed I want to lower and then raise core multipliers. Dont care to have my ram above 1600mhz.

Ultimately idle 1ghz and in game or encoding 4.6ghz is my goal.

70c is fine for the 2011 cpu
they can go to around 90c before thermal throttling

what do you use to overclock? I cant find anything :( thanks :)

[_nefarious]

bios

My stupid bios is so locked down...im on a compaq presario cq57 339WM and its @ 1.5Ghz but this software I have from intel says it can go up to 11.32 Ghz

You should be able to underclock a processor. Perhaps you have some sort of turbo boost enabled. 70C at max load for a 6 core is absolutely fine though. :)

70c is good? Seems high to me haha. was not aware the 90c was the limit for those.

Makes me feel better at least.
But I still think my thermal paste went bad. There are somewhat uneven temps across cores. Not to mention I used to get 60c at 100% load and 4.6ghz 1.36v (now it is that 70c)

I am currious though. Before I kept my clocks a solid 4.6ghz. Are there any disadvantages to allowing the CPU to idle at 1ghz or so? or is it better to keep it at a constant speed?

Use the bios. For intel cpu's you need a K or X serries. Otherwise you are more or less stuck with what it gives you.

If you dont like your bios, might want a new motherboard. But before you do that make sure your bios are actually up to date. You might fing they are changed and much better if they had been outdated.

leave it to hp/compaq to sell a k cpu in an oem system

70c while overclocked doing an Intel Burn Test seems perfectly fine to me. Its supposed to run hot when overclocked to that extent.

[Mr Moopsy]

I am still very curious.

Is it better to have ones cpu at a constant clock. say 4.5ghz 24/7

Or

Is it better to let the computer change clocks from say 1ghz to 5.5ghz and anywhere in between.

I just want to know if there are any advantages/disadvantages from the two.

the newer ones do a pretty good job at bumping up the multi/voltage when needed

for a 24/7 machine its better to have it use c1e and turbo
so it will idle down when not needed and save heat/power

I shut my computer off daily. By 24/7 I mean whenever it is on, it would maintain 4.5ghz.

But now I have it fluctuating from 1ghz-4.5ghz.

Cpu averages 0% usage at 1ghz when doing things like typing this, browsing internet and monitoring cpu(heat, voltage, usage, etc)

No. that is not underclock. It is the Intel SpeedStep. Also you proabably have Boost Turbo.

Intel SpeedStep is all thats needed so that the Overclock is only applicable when it needs to be.

You DONT want your Overclock to be active 24/7. Not only will it be giving off alot of heat even if your cooler can handle it, but the constant power draw will raise your electric bill.

EDIT:

OK did some major tweaking. And finally my voltage changes with clock!
clock is now 1.2ghz under normal usage(web, music, steam, etc) .85v to 1.0v with temps at about 25c
I am really happy with this.

I also bumped my ram up to 1866mhz from 1333mhz.

Edit 2:
So now that I finally got my "underclock" half of things working and at a point that I like it I decided get the overclock portion working again.

Now the cpu goes to 4.6ghz at 1.352v average. However temperatures range from 63-68c on my cores. Guess thats what leads me to believe re-applying my paste might be a good idea.

Ran about 30minutes prime 95 no issues. and 20 runs of Intel Burn Test, no issues.

I have a new tube of ThermalFusion 400 laying around. Is this a good paste? Or are there bigger and better thermal solutions these days?


Also...
That said, Could any1 additionally explain what c-states are?

I was testing things with 4.3ghz going to get back up to my 4.5 or 4.6 to see if my voltages and temps hold out the way I expect.

THey're power saver.
