Trouble overclocking on P43

Hi. I got a P43 with a E8500 a week back and after asking the community it was decided that this would be a better option than to use my 680i with the E8500. I've previously been using a Q6600 with my 680i and 2x2GB DDR800 patriots.

So took it out, put the P43 in (Gigabyte GA-EP43-DS3) and the E8500. The overclocking settings menus are very different from the nvidia ones, thats the first thing I noticed, but I couldn't get it past 2.70Ghz.. This is a chip that can get over 4Ghz. Played around a little but after trying gaming and seein no advantage over my Quad and getting anoyed I put my Q6600 back in.

I can't get it back to the 3.0Ghz that I use it on every day. 2.6Ghz max. Then I noticed... memory... How can I unlink my CPU and memory?

On my 680i this was not a problem at all was clear where to go and how to unlink. But I can't see how on earth I would do it on this damn board!

All I need is FSB333 multi 9x and my memory on 400mhz. Why is it so damn hard? Help please. I need this working soon as I need to sell what I don't use and don't want to sell my 680i if I'm going to have to go back to it.

Thanks
 
You can't unlink memory on Intel chipsets.

The BIOS should have plenty of memory ratios/dividers for getting the memory somewhere near its advertised speed. 1:1.20 or 1:1.25 should be close enough for PC2-6400 running with a CPU on 333mhz FSB..

Yup, its all about dividers.

Post up some CPUZ memory tab screenshots.

I had the same problem when trying to clock on mine, once I worked it out (with help on here!) its a dream :)
 
just went to get CPU-Z mem view up - its all greyed out? Never had that before. and SPD.... I'm doing something very wrong?

Where would I find ratio/dividers in the BIOS, don't remember seeing anything like 1:1.20 or 1:1.25 anywhere.
 
cheers guys. I found the right setting. Not sure what the D at the end meant but found 2.00D worked perfectly for me. Running 3.330Ghz atm starting prime.

Still anyone know why CPU-Z has now gone foobar on memory and SPD?
 
Not sure, although there was a new version release this weekend I think.

Every 'problem' i had with overclocking on this chipset was down to dividers. My bios doesn't present them very nicely. I had FSB Strap to NB (i think) and i just set these at different levels with the cpu at standard, booted windows and checked in CPUZ what the divider actually was and went from there.

But if cpuz doesnt work correctly then I dont know sorry! Seems the P43 chipset has some oddities with monitoring software. HWmonitor insists that my 12v rail is 5.4v for example lol
 
cheers. Downloaded new CPU-Z and worked. :D - well most of the table.

CPU-Z informs me: FSB: DRAM 1:1 - is that not the best you can get? Sorry slap me if i'm being stupid?

I dont think so no.

If your Ram is rated at 800fsb then you need to get as close to that as possible, or a little above if your ram can do it. The higher the better!
 
mmm ok, well the only other option was 2.66D and that put my memory at 880mhz or something similar. little disappointed really. 1 of my cores failed prime after 15 minutes as well. So 3.330Ghz isn't a sticker. Will try 3.2Ghz. I like round numbers
