I7 rig will not post with 3 dimms filled

When Installing your Operating System (OS), you need only use 1 dimm and start off by placing it in slot #2. After you get the OS installed, then add the other 2 dimms in slots 4 & 6. Start computer up and go into Bios', then to where you can change your memory timings or leave at auto. Once that is done boot into Windows and then shutdown computer if it boots with all 3 dimms (6gb) and then add the other 3 dimms in 1, 3, & 5 slots. That should solve your problem.

thanks for your reply

have tried the following

1 in bank 1 boots

2 in banks 1 , 3

works ok

works with ram in bank 1,2,3,4,5

not 6

all ram works in diffrent combinations

sticks are confirmed working

only the 6th (last ) dimm is empty

yes here is the the timings

9-9-9-24 ram is ocz platinum 7-7-7-? rated
2t
1.64v

but still no 6th dimm working

hi simon

what settings are you using ?

are you overclocking

It's also probably worth noting that I'm using Corsair 6GB (3x2GB) DDR3 1333MHz XMS3 Memory CL9(9-9-9-24) with an GA-EX58-Extreme. Are you using the same motherboard?

Is anyone aware of any problems with this board? Could a BIOS update resolve the issue?

I'm not sure if this is the latest...it's a case of the blind leading the blind at the moment I think! We need to stick around until someone more knowledgeable can help us out!

I won't be home for a few weeks to test anything but any information anyone else can provide would be excellent.

I'm going to re-post this (again): when the i7s approached release, I warned, long and loud, that this is not a good place for people with little or no systems experience to be. This is a completely new chip mask, with a completely new northbridge, a completely new memory technology ('direct connect three channel'), which requires completely new boards, with completely new BIOS! There were bound to be problems, and some serious! You should expect weekly BIOS upgrades, and scads of difficulties - it's, essentially, a huge 'public beta' project... If you have little depth of experience, and no knowledge of troubleshooting (hardware especially), nor have a serious reason to invest a lot of time in an untried platform - this is a really bad choice. If you expect building a computer to be like plugging in a toaster; if you're the sort of person who didn't do well in math or science classes (or just completely avoided them); ditto!

Everyone seems to think they've 'gotta have' the latest and greatest goodies that appear on the market - but a comprehensive set of untried technologies like this requires serious: effort, understanding, and, most of all - time! Most everyone I see here with X58 based problems would most likely have been infinitely better served to have stuck with a Q9550; I liken this situation to deliberately shooting yourself in the foot - and then complaining because you've got to change the bandage twice a week!

That said, the first point regarding these boards is the i7 setups show negligible subjectively noticeable gains from the currently available memory speeds:

so you needn't obsess about getting that last MHz that your memory is rated for... Slow 'em down to 1333, and see if they work.

There is also a great i7 tweaking article from GB tech here:

I have all the Intel docs re the i7/x58, and, given a week or two to digest them, should start to become useful for these problems!

Edit: also a good explanation of RAM vs 'unCORE' frequencies:
