Hey Guys,
So I've looked around the forums and have found a few threads with the same problem but haven't seen a solution that's worked for me. I think I may have narrowed it down to a faulty DIMM slot on my Classified E760 but want to make sure before I start the RMA process.
Here's what I've tried with my results:
1. Clearing CMOS and resetting Bios for stock settings.
2. Upping the voltage on the memory to 1.65v
3. Check msconfig for a maximum memory amount.
4. Reseat ram
5. Try individual sticks of Ram in each available slot.
Step 5 is where I've stopped. Any single stick on the first slot and the PC will not post. All three sticks on ram work in the other slots without any issues. I installed two sticks in slot 2 and 3 and the system posts with 4GB of memory. Installing the third stick in slot 1 the system posts with 6GB of memory (3.99GB usable).
It definitely seems like it would be a problem with the DIMM slot, but maybe I can run a few more tests first? Not looking forward to the RMA process at all as I have an EK waterblock installed on the motherboard :(!

I numbered the slots wrong. When I said slots 1,2,3 I was referring to the red slots which are actually slots 1,3,5.

You could run memtest86+ version 4.0 on each stick to make sure they all pass. Otherwise it sounds like you have troubleshooted well and you might have a bad DIMM slot. Did you save all of the ORIGINAL screws/pads/parts from the board before you put on the full coverage block?
EDIT: you are using a 64 bit operating system, right? sorry for the stupid question, but I gotta ask em all heh

since you seem to have tried quite a few of the fixes for this problem, i would also either try reseating the cpu or just try loosening the screws for the cpu heatsink since with my board if i have my waterblock screws too tight the board will only read 4gb or but if i loosen it up a bit all 6gb are their. if you have too much pressure around the cpu socket the board could flex a bit and some pins might not be making contact or their is just too much pressure on the cpu, you may also try putting the stock heatsink on a testing if all 6gb are recognized

Luckily I kept everything that came with the board... this is going to be an absolute nightmare though. lol
I am running windows 7 64 bit.
I should also add that I ran memtest briefly when I did get the board to post, like I said, it doesn't post at all in DIMM slot 1.

I would give what AJ just mentioned a shot as well, just to see if that is causing it, and then give EVGA a call to see if they can give you any info. They might very well want you to RMA the board :\ A board that wont post with anything in slot 1 is not a good sign unfortunately :(

I've reseated the CPU, (should have mentioned that :P) and I highly doubt that It's too tight as I used a digital caliper and a heatkiller block with backplate when I installed everything and was very precise.
I'll loosen it just a little and see if it works but I highly doubt it :(

just to let you know the mounting hardware that comes with the Heatkiller block allows the block to be tightened down way more than is need

couple questions First what qpi are you running? a lot of x58's lose 2gb of ram in some fluke in the low to mid 180's. Second when you say the red slots... nvm googled the image answered that one myself.

ive had the same thing happen on my last x58 board... its a very common problem due to the insertion of the cpu. id even say its the no.1 RMA problem.
if youve tried all the memory sticks individually in the other slots and they work but not the first 2 then its most probably during installation of cpu its not been placed into socket correctly as in if the cpu goes in at an angle or dropped gently in or even installed using cpu corner to drop into place...(just examples) it can lead to some bent pins which then disables the first 2 dimms.. if you have the tools and good eyesight you can straighten them yourself but safer doing RMA where they just remove the cpu socket and install a new one.
doesnt help anymore when the classified have softer pins than standard x58's due to the higher gold content.

The only thing that keeps me from thinking it's an installation issue is that everything was running properly since August and it's just recently that I noticed the problem. Basically when I started doing editing again I noticed it wasn't running properly and that I was using all available RAM.
It's somewhat confusing because I've built many PC's and have never had any issue placing the CPU in the socket or with installing the heatsink. When installing the heatsink I used the exact specs posted by heatkiller.
It might just be time for me to bite the bullet and initiate an RMA, the only thing that's keeping me from going crazy is knowing that I have a spare Asus Rampage 2 Gene to use in the meantime.

After all you have tried/say you have tried, I would say call EVGA and see what you can get rolling at this point.

Oh dear god the horror...
Turns out I registered my GTX295's, my X58 micro but NOT my Classified.....
I guess it's fine since it's within the year but that's still a really stupid thing to forget :P

They might be able to help you figure something out, you never know. Someone else might have an idea as well, but at this point its sounding like a bad DIMM slot..

Maybe I am just blind, but I don't see it. ... You have tried increasing CPU uncore voltages, right? Specifically, you have tried increasing CPU VTT +50 to +100mv, right?
A list of your present BIOS settings ("BIOS Template") would be nice for reference purposes.
I also have to ask whether you have tried loosening up the screws to your CPU waterblock yet. I know someone already asked. And then you said you didn't think it was the problem. And someone said you should confirm. And you said you would try it anyways. But you still haven't confirmed that you have tried loosening up the waterblock significantly yet.

I apologize for the lack of clarity!
I did indeed loosen the screws on my waterblock. I tried doing it in increments of half a turn with no success. I will take down my bios template as well, but I have indeed increased the voltages I think I tried all the way to +300 vtt even with the ram severely underclocked.

Yeah, I was going to post my bios template, but currently it's at default settings except for raising the VDIMM to 1.65. I've also tried increasing VTT. I decided to submit a ticket, I guess I'll see where this goes.

My 760 had the same problem - intermittently booting with 4GB in BIOS or 4GB in Windows (6GB, 3.99gb useable).
It had a loose memory slot, which may also indicate a faulty memory slot.
It was RMAed to Newegg.
Never experienced 6GB/3.99GB useable ever on my 758 (which is what I'm currently using).

You don't have a 285 2GB card do you, Video memory is shadowed making it unavalable.

Any news on your solution OP?
I am having the same problem.
this is OS or mobo related, my RAM has been fully tested. I have 12 GB Mushking Redline memory 6-7-6-18 at 1600mhz.
For some reason, the only way for the OS (w7 64bit) to use the full 12GB (as opposed to 9.99 usable shown in My Computer's properties) is if I change the target frequency of the memory to, for example, 1333mhz AND THEN BACK to 1600mhz.
When I do that, then the full 12gb are usable, but the morning after I have to do that annoying procedure again. I mean, what the ****. I didn't spend all that money for this crap.
The memory is NOT the problem as I already tested it for hours with different memory checkers and also in other computers that don't have the x58.
I don't know honestly if the problem is being caused by w7 either.
Could somebody please help me.
Let me know if you need more info on system settings or anything.
I am using the stock SPD settings for the mushkins.
I tried everything the OP has tried.

The 12 GB won't run at stock settings.
The answer is buried in this forum, don't remember right now what it was. Relaxing the timing as I recall.

I had a problem with my x58 Classified motherboard, I had 12Gb installed but only 9.99GB was usable. The problem was fixed in msconfig
Go to windows 7 Start menu then type msconfig then go to boot>Advanced options then uncheck Number of processors & Maximum memory then Restart your pc & see if it changes.
It worked for me & now I have the full 12gb working At Last :) I've been trying to sort this out for 3 months & only fixed it today
Hope that helps Cheers Colin.

I am having this same exact issue intermittently. Sometimes I boot and it posts the 6 GB and Win 7 shows all 6 GB and other times I boot and it posts 4GB and Win7 shows 6GB (3.99GB usable).
Has anyone opened a problem to EVGA support?

I have this problem too, 1333mhz works fine with 6gbs but soon as I change to 1600mhz no mater what I do bios only picks up 4gbs but windows recognizes there is 6gbs buts shows 3.99gb, I have just replace my corsair memory with Dominator corsair memory now also, I highly doubt it the memory and, which is 1-3-5 the memory suppose to be in or 2-4-6 my manual tells me 1-3-5 which how i have it set up even if it should be in 2-4-6 i cant put them in those slots cause my Cool hs blocks the first slot, I'm about to return the board under the warently I got with and and wana know if i should even both to replave with same board or get x58 SLI or should i get higher model, cause this is annoying

i would think probably its a windows problem. if not, why dont you try switching the ram sticks around or maybe installing another type of os. ex vista 64 bit or xp
