Overclocking Using DDR2-1066 On AW9D-MAX/ E6600

So, the vmch sets the voltage to the northbridge, but in this bios it states 'vmch/pci-e voltage'. So the pci-e card is tied to the nb? So how is it safe to crank this up? Surely this will kill my gfx card? Its at 1.55v. As always, help is greatly received
 
It shouldn't kill your GFX card basically I think this is just the MCH voltage rather than specifically the voltage your GPU will recieve (which regulates it's own power)
 
If it is tied to the PCI-E bus (which the name suggests) then it will actually increase the voltage to the cards PCI-E slot.

This won't actually make any difference to the performance or overclockability of the card as the card regulates its own memory/gpu voltage (as kemp said) - but it may be an idea not to go too mad with this setting as there is a chance (be it very small) that you could fry the card if you take it too far.
 
Going by what people are saying on XS there seems to be quite a voltage droop on the nb - MCH@ 2.0V in the BIOS is only in reality ~1.82V when metered for a lot of folk.

Hey Buff, does this mean that my 1.6v in the bios is actually 1.4v in reality? Do I need to go up to 1.8v to actually get 1.6v and this might get me better stability for higher clocks?
 
I doubt that 1.6V in the BIOS is only 1.4V but you can only be 100% sure by metering it.

Check on XS for HiPro's Vmod as that supposedly gives you pretty much what is set in the BIOS for the higher voltages.

i run mine at 2.0 all the time, thats the only way i can keep it somewhat stable in the low 400s.
 
My RAM is a POS. Error city on mem test and I'm pretty sure it is the reason I can't get a higher stable OC.

It's rated at 1066 yet whenever it comes close to this it becomes unstable. I think 900mhz is about its limit...

Last night I spent aaaaages playing with voltages, timings and dividers in the futile persuit of a higher stable oc. I can boot up at 3.6/3.7 but mem test, 32m superpi or dual prime always fail.

I had my mch at 2.0v, cpu core at 1.55v, ram divider at 1:1, stock 5-5-5-15 latency, ram 2.3v, 400fsb*9... Grrrr! Idle temps at these settings were high 30's (37-39 degC) load high 50's. These volts are as high as I think I should go.

If I have a 4:5 ratio on the ram and put a fsb in to run the ram at approx rated speed, say 1050, then the thing wont mem test or prime etc. If I back down so the ram is around 890 then its ok. Thats why I went to the 1:1 divider, to give headroom on the ram/fsb setting... This got me my 3.6 but, again it wouldn't prime etc.

Then I fettled with settings focusing on ram, it just errors if I go over 367*9 regardless of dividers or voltages.

Is this mobo a bit turd? Or is it the ram? Or me? Am I a big overclocking turd that doesnt know what he is doing?
