Asus P5E Deluxe Motherboard
Thermaltake VA8000B Series Full Tower (This thing is good at thermal control)
(CPU has the stock heat sink on it for the time being. Waiting on next paycheck to replace it.)

Okay. I am new to overclocking so I entered my bios with a very careful plan of attack.

THE PLAN===>

Use a USB Flash drive to make a backup of all bios settings.

LOOK over all the settings very carefully

Use that information to "PLAN" a future overclock...
---------------------------------------

I made my backup of the bios settings on my keychain flash drive. Then I verified that I could restore that backup okay.

After I restored the settings to the bios, I booted windows.

---------------------------------------

For some reason, my CPU was then running at 2.0 GHz instead of it's stock 2.67GHz... After investigating I found that my CPU was running at 333.3MHz X 6. (333.3*6=2000MHz)

Somehow, going into bios and making a backup of the settings... And then restoring those same settings... Changed my CPU clock speed.
---------------------------------------

To make a long story short... I changed the multiplier from 6 to 8 (Where it's supposed to be) and now my machine is back at it's stock 2.67 GHz CPU speed.

HOWEVER, it now seems to be running hot... 60C - 71C depending on load.

What gives?

- Witt

PS - Going to submit this forum thread, then shut down my PC and open the case... I am going to verify that my heat sink is still seated correctly.

Okay, I opened my case and checked to make sure the CPU Heat Sink was actually mounted correctly.

To be honest, the mounting system on that heat sink is so cheap I can't tell if it was seated correctly or not.

The moment I touched it, I heard a pop, as the mounting foot came out of it's socket. Not sure if my touch is what un-seated it or if it was not properly seated to begin with...

--------------------------------

So I re-seat the heat sink and restart my computer.

It's running at 2.67 GHz (333.3*8)

Now my temperatures in Real Temp seem correct. (35C - 50C) depending on load... But SpeedFan is reporting crazy temperatures. (-128C - 93C)

For some reason, I choose to pay more attention to real temps readings. lol!!

Please advise...

Any information would be very useful.

maybe the BIOS figured the temps were too high and clocked it down to 2.00GHz? weird never heard of that one before...

umm with the whole USB backup thing....if it doesnt POST just reset the bios, lol?

and yeah it would be running hot with some crappy stock intel cooler :(

although not as hot as speedfan reports, LOL!

^Speedfan's reporting negative temps!

The 2.0GHz thing is actually how your computer should look when running totally stock idle. EIST (speedstep) kicks in and knocks your multiplier back to reduce the frequency of the CPU then lowers the CPU voltage slightly. So if you then put load on it, the CPU should jump back up to an 8x multiplier for the ful 2.667GHz speed. Glad you got things situated properly and have reasonable temps.

Oh, and V3NOM - if your CPU does get too hot, it will throttle. I've never seen it happen, but it's possible that's what it would look like... though at only 70C, I doubt it was throttling.

^ lol i know speedfan was reporting wrong temps, it was a joke -_-'

and yeah shouldn't you turn off speedstep when overclocking? :O

and yes, the whole throttling thing if temps gets too high is extreme - try 100 or 200Mhz! :( this is incase you have no HSF on, and therefore if it clocked it at even 1GHz it would probably explode LOL!

Resetting the bios would have worked just fine. Howerver, once I get into the OC'ing process I am going to be taking things forward one small step at a time... Once I hit an unstable configuration, I will want to back up just one step... Resetting the bios would start me back at the beginning.

That was my thinking about the USB Flash drive for bios settings.

- Witt

PS - LOL, I never took the Speedfan temps seriously because I saw no fire and brimstone being flung from the back of my computer case. :kaola:

I think I have taken this OC"ing thing as far as I am going to, until I get a better heat sink.

Since my stock heat sink popped off it's mount, I have broken the thermal compounds seal to the CPU.

Currently I have no compound cleaner and purifier, and the only thermal compound I have with me is some really crappy 5 year old ceramic stuff.

In about 4 days, I will have a Zalman cooler, Arctic Silver 5, Cleaner and Purifier, etc, etc...

I will pick this overclocking back up when I get that all installed.

- Witt

PS - How long is it going to take for my silver based thermal compound to set up? 14 days? or more like 30? Everybody always says " A couple of weeks " and that is pretty vague.

Oh, one more thing...

The heat sink... I am thinking about ordering the following heat sink.

http://www.newegg.com/Product/Product.aspx?Item=N82E16835118019

it seems to get very good reviews and on top of that it has MORE BLUE LED LIGHTS!!!!

However, if you guys know of a CPU cooler that works much better than this one... let me know, please.

- Witt

PS - Also getting these this order....

http://www.newegg.com/Product/Product.aspx?Item=N82E16835425002BLUE LIGHTS! WOOT!

Based on this thermal compound review (thanks WR2) The following compounds would really be better than AS5. They don't require a burn-in time, which is a big bonus... but if you're already getting AS5, no real harm done. http://www.newegg.com/Product/Product.aspx?Item=N82E16835154003

Also, it's really unlikely that you'll need that RAM cooler, unless you're doing some very serious overclocking beyond 400MHz FSB with DDR2-800 RAM. (with a 1:1 ratio, which is the most common).

That Zalman is quite popular, and performs very well, but may not be worth the price increase over http://www.newegg.com/Product/Product.aspx?Item=N82E16835233003

I don't think it offers quite as high performance, and it costs more! With the retention bracket, I don't think the Xiggy will be difficult to install at all, but should provide excellent cooling.
