I put 2 gigs of mushkin PC8000 in there, and no matter what, the board was not able to post anywhere past 400 with 2 gigs of ram.
I think I know why too.
bandwidth is drastically higher when you have 2 gigs of ram, then 1 gig of ram, atleast, according to the only thing that would still boot with 2 gigs of ram in it... Memtest 86.
I suspect that the bank interleaving for the stock DFI bioses, just makes the chipset too stressed out, which is why it barely OC's when you use 2 gigs of ram in it.
put 1 gig of ram in the board, and use the 400 mhz setting.
my other settings that I dont know if they help others, but I use.
1.35 VFSB.
1.75 VMCH.
101 mhz PCI E.
PPM Off.
Manually set the cas, ras to cas, TRP and Tras.
for the maximum OC possible on this board, theres a really solid method that works for me, when trying to boot at over 400+ on the FSB.
this takes multiple boots, and has to be done the same way everytime for this to work.
1. after a cleared CMOS. in bios, disable C1E, Execute disable bit, and Virtualization (nothing uses it anyways yet)
in your integrated peripherials, disable anything you dont use, and enable the raid if you use it.
set your CPU speed to manaul, but dont change anything yet.
reboot.
2. change your cas, your Ram divider, set your PCIE to 101, set your voltages, and set the hard drive you need to boot from.
Enable the "recover from failed OC" option and set it to 15 mhz.
the board has one of the best features I have ever seen on a Intel Based Chipset... the recover from failed OC option can save you alot of time, if you use it right.
say you know the board will boot just fine at 350 FSB... well do it.
get back into bios, and then OC by 15 mhz on the FSB. try that. if it boots cool, if it doesn't, the board will lower the FSB back down by 15 mhz, and load the last workable boot.
OC by 15 mhz intervals and you can save yourself alot of headaches having to clear the CMOS, cause this board, like all intel boards seems to have the same annoying thing if you OC too far... it won't ever recover from a failed OC, and needs a complete clearing of the CMOS and starting all over again, if you get too aggressive.
thats why overclocking in 15 mhz intervals can really save you some time on this board...
or if for some reason you set the recover from failed OC option to say 5 mhz, then OC only in 5 mhz intervals... that way, the board has a drastically higher chance at recovering from a failed OC, then if you dont use this option.
reboot.
3. if you have everything set, your ram speed, divider, cas, your boot drive, your voltages and everything you dont use disabled, then by now, theres only 1 thing left to do... adjust the FSB.
this is key here, save the FSB for the last thing you change, and your luck with this board should be alot higher.
and absolutly never, change your FSB and your boot drive at the same time.
I have no idea why, but thats the quickest way to garauntee you will need to clear the CMOS to get the board to boot again...
so thats the one thing you got to always remember to do.
also, from my experience, this board doesn't like having the FSB and voltages changed at the same time... and will most likely again result in a failed boot, and needing to clear the CMOS.
I have spent hours and hours going over and over this board and it's various bioses and figuring out what makes the board work the best, and this is what I do everytime.
if your not gonna take my advice atleast take these two things into consideration.
dont adjust your FSB, and set your boot drive at the same time...
and...
use the "recover from failed OC" option, and adjust your FSB in the same intervals you set the "recover from" option at.
atleast these two things should help most of you.
this is my method, it works for me.
I wont claim this to work for any other board, but I know this method works for me, cause I've done this exact method about 1000 times so far, haha...
