Problem with overclocking E6300 + Asus P5B-Deluxe - Page 2

post #11 of 17
BTW 350 FSB with DDR2 875 is not 1:1, my friend. 350 FSB with your RAM at 700 MHz would be 1:1

Try accomplishing a 400 FSB first before breaking that barrier. Keep the timings for your RAM to set by auto SPD initially before even thinking about toying with memory timings. Crank up your FSB termination voltage. Leave the NB Vcore as is and run the memory at 2.2V. What results do you get now? The overclocked frequency should be displayed during POST, as well as how your RAM is running (PC2 5300,6400 etc)
Raver 123 is right:

Vanderpool: Off
Execute Bit Disable: Off
CPU Multiplier: Off

Static Read Control: Off

* I would set up your DDR timings manually

Hope this helps

Thanks for your suggestions. I tried all of the above suggestions but the speed is still capped at 2.25GHz.

At BIOS startup, it would show 2.33GHz. Even if I've saved 380 or 420FSB in BIOS, the speed still gets stuck at 2.25GHz (321FSB). Something is really limiting this and I dont know what.

It could be your PSU Limiting it. Check Your voltages in Bios

Try enabling the spread spectrum option and see what that does. Go with all the settings as described by myself and others in this thread. Everything you have under CPU Advanced options must be disabled. What are your CPU fan options set to? Try and set them all to 'Performance' mode. What you can do is take screens of your entire BIOS with these changes and someone with the same Mobo will be able to identify what the problem is. Post some update screens with the changes and this time post ALL of them. This will help us help you. Your also better off not fooling with memory timings at all... not just yet until the system boots right at AUTO.

Maybe try the 0507 BIOS (if you haven't already). We have similar systems and I was having difficulty until I re-flashed the BIOS to 0507. Also the RAM timiings I use currently are 4-4-4-12, Vdimm @ 2.1.

Is a 8x multi available to you now? Have you tried that in cunjuction with a 1:1 ratio? If not, then BIOS 0507 will unlock the multi and provide 6, 7, and 8

As others have mentioned, your Vcore is a high - take it down to, say 1.34 as the voltage is not the cause of failure at this time.

I would also leave the NB Vcore at "Auto"

Guys it's solved!

My problem is solved and now it's running at 370FSB. I can't get higher than that for some reason but I am quite contented for now. What I did was as 1xe pointed out in another forum:
Flashed ROM with 0614
reseted CMOS (just jumper no battery removal)
Flashed ROM with 0614
and again reset CMOS (just jumper no battery removal)
