Did you mean you want this >>
CPU Clock Ratio ____________ [10]
Fine Clock Ratio ____________[0.0]

If so, ok! Just kinda confused there for a second the way you worded that.

4GHz is alot to ask from a quad for sure. I would also be using 399 FSB (For 4.00B) and or 401 FSB (For 4.00D) And you may need to loosen up your ram to run that fast. Keep in min 2x2GB does hinder overclocking. Your vdroop from 1.36 to 1.31 at load is alot, you are for sure going to have to add more vcore above and beyond so that it does not drop so low at load.

Try this and see if you get anywhere >>>

CPU Clock Ratio ____________ [10]
Fine Clock Ratio ____________[0.0]
CPU Host Clock Control_ [Enabled]
CPU Host Frequency (MHz)__________ [399/401]
PCI Express Frequency (Mhz)_______ [100] << Ouch, always set this when overclocking, otherwise in Auto it is overclocked as you raise your FSB (100-105)

Thanks for your advice, much appriciated. I'll try your suggestions now.

I tried with the suggested settings, apart from the vcore - I got 1.364v from the Intel specs as the max and don't really want my idle to exceede it for 24/7 use. I can run memtest without error but still get the same 20 mins prime or 1 Intelburn and then errors, so I'm guessing its the vcore that I need to overcome the droop. I thought that I might of been missing something and I'd be able to get 4.0 stable without such a high idle vcore which is why I asked for advice. I'm thinking I'd rather stay at 3.8 with reasonble voltages and tight memory, and again - thaks for your help.

Re: GA X48T-DQ6 + [email protected] - help appriciated

More vcore is for sure needed. Are you using 1.365 MAX as per your BIOS setting, or what you actually get used shown by CPU-z?

More FSB and MCH Could help, what did you have those set to? And what all have you tried? Ya, you should not need such a high vcore, but with your boards droop you may just have to have it to keep stable

1.40625v is the highest bios vcore I've tried, it gives 1.360v idle in windows but the vcore is measured in 0.016v increments so if I go up 1 more notch it's 1.376v idle which is more than I want.

I've tried with the lower of the suggested (tighter mem, lower volts) and the higher (looser mem, higher volts) with FSB 399 and 401 with the B and D straps. But I can't put the MCH over +.3 because it overheats (after a 5-10 mins of memtest the screen goes blank but the power stays on and I have to reset).

Then I tried with the mem on 2.00B divider and auto timings (Left at +.4v) to be sure it wasn't a problem and lowered the FSB until I got stable at 395x10 and also tried with 9.5 multiplyer and raised FSB to get to 416x9.5 stable but either way couldn't get to 4.0Ghz using 1.40625v in bios for vcore and MCH+.3v, FSB+.2v so I gave up :( thinking I won't get it at that vcore.

I lowered the FSB a little further to 390x10 to get the memory back to cas7 and performence level 6 on the 4.00b divider because it gives a much better bandwidth for the sake of .05Ghz cpu clock.

I have the vcore as high as I want to go but wasn't sure if I could get to 4.0Ghz by manipulating other settings but i'm starting to think I can't.

Thanks for your help and time.

Hmm, sounds like maybe you should add a fan to your NB, or at the very least redo the thermal paste under it. If you do, use NON Conductive

Did you ever try MCH +.25-.3 with only +.1 or none to FSB? That may help with the heat issue
