So i o/c'd my e8400 and whacked a heatpipe cooler on it, in my BIOS i have it currently at 3.4Ghz, and up'd the voltage a tad, but when i check with RealTemp, it's still running at stock speed...is there something i'm doing wrong?, ugh
Hello, make sure your reading guides on OCing otherwise you could stuff up badly. You could have speedstep on which lowers the multiplier when the processor is not being used, to get the correct speed you use Prime95. If you don't know what Prime95 is you obviously haven't been reading guides and therefore shouldn't be OCing.
Yes. What happened was the BIOS didn't like something about your specifications overclock settings and kicked it back to stock speed.
An E8400 should be able to run at 3.4 GHz with little or no vcore increase. I suspect that you left your memory settings on Auto and that you are now trying to make your memory run faster that it wants to.
Here's what I am talking about: Let's say you have an E8400 and you are using DDR2-800 RAM with it. At 3.4 GHz, your FSB freq is just under 380 MHz. Your memory is running at (380/333)*800 or about 910 MHz.
So let's start over. Clear the BIOS to restore factory values in the BIOS.
Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the System Memory Multiplier (or whatever your BIOS calls it) from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. This is for a Gigabyte motherboard. Asus and nVidia chipsets each use a different scheme.
Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 333 MHz, your memory clock should be at 667 MHz.
Download CPU-Z to check your FSB:RAM ratio. It should be a 1:1 ratio.
Then continue the "increase FSB, test, increase voltage" overclock cycle.
Don't exceed 1.45 volts vcore. And don't exceed 70 C load temps.
