Re: 4Gb RAM Won't boot :(
Perhaps they aren't set at the correct voltage in the bios? Or one of them is a duff stick?
Tried memtest?

but try what staffsMike says first to rule that out...
Re: 4Gb RAM Won't boot :(
Most Northbridges need more voltage to run 4 sticks. My QuadGT won't post with 4 sticks without a boost to it.
Re: 4Gb RAM Won't boot :(
Any ideas what voltage to up it to? this is the RAM: the webproduct ID from scan is 585722 (i cant post links yet lol)
I've never tampered with voltage before... done a little Mz tweaking though lol
Thanks for your help.
Also i've heard memtest mentioned before but not used it yet, i'll give it a try although how can i use it if i cant boot with all the RAM? is it a software program? sorry, i'm a little 'inexperienced' in this area :(
Thanks,
Adam
Re: 4Gb RAM Won't boot :(
just bump the voltage up a notch and see if it stabilises it, and just try it a notch at a time :)
it shouldn't need too much, and if it isn't working after you've bumped it by 5 (dependant on the size of the increases....) or so notches then i'd try other areas
and memtest86+ you just download it, burn it to a disc and boot from it and allow it to test the memory with a few passes
Re: 4Gb RAM Won't boot :(
are you using the bios default volt (1.8v?) on the rams? may bump that up a bit as well
Re: 4Gb RAM Won't boot :(
Ok... I'm on holiday at the moment so i'll give memtest a try when i get home.
About the voltage, it is set to 'auto' so i'm not sure what the 'auto' voltage actually is, what is an average voltage for me to start at?. I'm on an ASUS P5N32-E SLI Mobo if that helps...
Thanks for all your help :)
Re: 4Gb RAM Won't boot :(
Auto is generally 1.8v. Some RAM needs more. But check that yours does before upping it.
Re: 4Gb RAM Won\'t boot :(
I am using the P5N32-E SLI and having the same problem as well, but I am using Win XP 32bit. Will try to increase the NB volt and see what happens next.

You are probably aware of this already, but even when you fix the booting issue, Windows XP (32bit) will not support the full 4gig :)
Re: 4Gb RAM Won't boot :(
Could it be that your mobo does not like that make of ram?

I know that XP 32 bit won't recognise all the 4G RAM, i am planning to upgrade to Vista 64bit also to take the full advantage of DX10.
UPDATES: The RAM voltage was set at 2.1V and the NB voltage was set up to 1.45V, but I still can't get the PC boost up using 4G RAM.:O_o1:
Re: 4Gb RAM Won't boot :(
Specifically its the MCH voltage you want increase, on the P35 boards that I have there are different voltages for the fsb and MCH etc.
