Hello,

I know this probably isn't in line with all the i7, and quad core overclocks going on here, but i've ran into a problem when overclocking one of my rigs at home.

Components are:
Gigabyte X38-DQ6
E4500
2x2GB Corsair C4 DDR2 800Mhz DXH
Corsair 750TX

Now i've been running this for the last year @ 11x285 - 3135Mhz and since i lapped the Thermalright 120eX and the CPU today i thought i'd give it another shot.

Now here's the setting i've changed in the BIOS:
CPU Vcore: 1.42500V
FSB: +0.15
Northbridge: +0.1V
DDR: +0.3V (~2.12V)
Memory divider: 3.33C (memory runs @ 950Mhz 5-5-5-18)


My problem is this. Every time i try to run FSB memory 1:1 with these setting:

FSB: 400 up to 430Mhz
Any divider: 2.0A,B,D

When windows loads CPU-z says the FSB is 390Mhz. No matter what i change in the BIOS it won't get over 390. If i try about 460Mhz, it just won't even boot.

On the other hand 11x296 - 3256Mhz, works perfectly for 12hours Prime95 and memtest. But i can't even boot if i try 11x305.

What am i doing wrong here? I haven't really OC'ed in the last 5-6 months so i probably forgot something obvious, so ANY help is much appreciated

Thanx,
Tom
 
I don't know if this will help with the X38-DQ6, but I have had my P35-DS3L wig out before and wouldn't overclock at all, no matter what I would set in bios. My fix was to pull power, jump the cmos jumper and pull the battery and let it sit like that for an hour or so. When I put the battery back in and unjumped the cmos I was able to boot normally and overclock just like before. I haven't had any problems such as this with my X38-DQ6 though, but then I'm running a QX9650 and not a 200 fsb proc in it like you.
 
Nope.. not working.
Still the board won't let me go over 390 FSB...

Well i guess i'll just give up :D
On the other hand 291x11 is now 2 days memtest/Linx/Prime95 stable :)
