OC Further

[psaila]

So finally I got rid of the stock cooler and bought a monster, well at least it looks like a monster. I bought the Akasa AK967-Nero. Now my e6400 oc-ed to 2.84Ghz heats up to around 58C when running Prime95.

I want to OC further to 3.2Ghz because I read that this CPU can handle it however when I put the Frequency further than 355 it does not recognise the hard drives and so does not load windows.

Somebody mentioned that I have to increase the voltage of the RAM. Is that it? And if yes how much should I put it?

Thanks

It would be really helpful if you filled this out:

CPU current frequency:
FSB:
Memory Speed:

CPU Voltage (Vcore):
FSB Voltage (Northbridge voltage):
Memory Voltage (Vdimm):

DDR2 Memory can go up to 2.1V without much worry about damaging it--but make sure that your memory speed isn't too high! Raising the FSB also raises the memory speed, so unless you've lowered the memory speed/FSB speed ratio, your memory is most likely running too fast.

I'd also suspect your northbridge voltage--it could be that it needs some more current to keep it running stable.

Just lower the memory speed. Right now you have 667 ddr ram, which is 333 mhz. Set your ram in the Bios down to 266mhz, or even 200 mhz just to make sure you ram isn't holding back your CPU overclock.

No need to overvolt the ram, just set it to run at the proper speeds.

You told me to set the RAM frequency to 266 or 200 however when I went to BIOS I could not find where to change these. The only thing that I found was DRAM frequency and the settings where: auto, 533, 710, 888, 947 and 1183. What can I do?

Set it to 533 right now--that will make it low enough that it won't be limiting your CPU overclock. Then, when you have reached the overclock you want, you can try raising the memory one step--if it boots, great, and if not, you can keep it where it was!

But he said that at the moment it's running at 333MHz. If I put it 533 it would be too much or we're talking about different numbers???

The number the BIOS is reporting as the RAM isn't the frequency, but the number people go by--533 in the BIOS would be equivalent to DDR2-533, etc. Your Ram is DDR2-667, but probably could go higher--just start low so you know that the Ram isn't what's holding you back, and then you can adjust it higher if you need to once you're done overclocking.

At the moment it's set to auto which should be 667 however if I put fsb more then 355 it does not detect the hard drives. So as you explained the motherboard offers only the 533 lower than 667 because the next step is 710. I'll try to lower it to 533 and increase the fsb slightly and see if it boots.

My BIOS is old but I am afraid to flash it because I am not some expert.

Whats it set to now? The 710? If so yeah set it to 533.

Your Bios simply shows the double data rate, not the real rate.
