Can't overclock E8400 to even 3.1Ghz - Page 2

post #11 of 30
I had the Gigabyte P31 board and its rubbish. Well...its okay, but don't expect any miracles. I got a P35 board in the end because it was better at overclocking and it supported 4GB RAM properly.

Also, what voltages do you have set in the BIOS?

My guess is that the ram ratio is set too high and the ram is running too high. That and the board defaults to 1.8v, and the ram at 1066 most likely requires 2.1v - 2.2v to run. So they might be undervolted. Check the manufacturer's specs.

open up a few cpu-z's and have each tab open on different one then take a screenshot...

From reading the others posts seem they interested in your ram speed and ram voltage(which wasn't included).. So just open up 4-5 cpu-z and click on each tab.. arranged it so they all are visable then takk a screenshot.

Cool, attached is the screenshot...

You will have to do your vcore manually, and make sure you take off the speed step in your BIOS. It's making your processor run at a lower multi to save power.
post #17 of 30
Hmmm. You still have power saving options turned on in your bios? looks like speedstepping / C1E is enabled (or maybe you reset your settings?)

Also I don't know how to read cpu-z that well yet... But your ram is at 500mhz so it's speed is 1000? And I don't know how to read the voltage for the ram either. However it looks like it is 1.8V. If your ram running at 1000 and your volts are 1.8 that could be the problem.. may want to bump that up to 2.0.


EDIT****After you disable speedstepping retake the screenshot*

Cool,

Just one question though, what happens if I change these settings and I had the issue last time where I couldn't even get into my BIOS? Do I just keep restarting until it goes into the BIOS again or whats the story there? Last time I went through this it was not fun, any tips you can give me if things go pear shaped?

ok... when you start OC'ing you will encounter errors where the pc won't boot and you can't get to bios. In these situations you have to reset the bios... There is 2 ways to do this depending on the motherboard.

Check your manual for a reset jumper. On my board it is marked cmos reset jumper. But look through your manual it will tell you how to use it.

The next option is to take out the cmos battery for 5-10 min. Should see a round battery somewhere on your board.

When you do this it will reset all your bios to default so you may want to write down what you changed and what it was last time it was working and just change the bios back to the last working settings.

Cool,

I feel a bit safer now.

Which exact setting in the BIOS is Speed Stepping? I don't see anything like that. The closest thing to C1E I see is called CIA (Computer Intelligent something).
What tab is it under in the BIOS?

Thanks
