Hi all,
I have discovered this problem with my setup. I've had this running almost one year and honestly cannot tell you if this has been like this since the start or occured recently. I am running with reset to defaults on the original bios which I cannot flush for anything at the moment. I've been running stable overclock @ 4.2GHz with RAM at 2000MHz for all this time with no direct bearing on this issue (oveclocked or stock it is still present). No matter what I put the QPI PLL voltage or MCH strap it is all the same.
My setup is i7 920, Dominators GT 2000 C8 6GB, Classified E759, OCZ Vertex 256GB, 2x Geforce 285s, 2X WD Caviar Black 1TB in Raid. Everything is currently at default. Running Win 7 64bit.
The problem:
RAM shows up as 6.00GB but only 3.99GB in windows. In Bios it shows up as only 4GB installed and Eleet shows also 4GB in dual channel configuration. I have the sticks only in RED slots.
This is where I am with it so far:
I took the stick from the closest red slot to the CPU and I have still 4GB in bios but 4GB installed and usable in windows now.
If I take this stick that came from slot one and put it in slot 3 or 5 I only have 2GB of RAM. Thus I concluded that the stick that was in slot one is faulty.
If i interchange the remaining sticks with each other still have 4GB. I concluded that those sticks are good then.
No matter what I put in first red slot (closest to CPU) (slot one) the system does not post and goes in infinite loop of 4 errors on the led. I am thinking that slot one is also bad.
Wow, this remains me of word problems in algebra :-)
Ok so before I go RMAing away I need some input from you guys. Please feel free to let me know if my conclusions are correct or if you want to ad something to it that I may have missed. Thank you for you valuable input!

I would first Load defaults and check it at stock settings, If you have all your memory at stock defaults, and dont when OCed, than it would be safe to assume that it is a setting issue. what do you get at 20X133 with a 2:8 and 1.5 DimV ? after you find out, Try a 2:12 with 1.65 DimV for 1600, and if that's fine than drop bak to 2:8 and go back to you OC. depending on your results, you should be able to figure out which settings are causing the issue. you may also want to increse Vtt. as the IMC is inside the CPU.

Sometimes giving the Memory stick a little wiggle in the slot helps, i had the loop error with 1 stick in the red slot closest to the CPU, removing it and putting it back in then giving it a little wiggle solved it. Another thing to keep in mind is that it may not be the memory slot, it may be that the CPU is not sitting 100% correctly in the socket and Channel A on the IMC is not able to connect to the first red socket. this can sometimes be down to uneven pressure on the cooler, sometimes one side is tighter than the other. Removing the CPU and reseating it may help. Since you mentioned QPI PLL in relation to memory issues i want to point out then when memory manufacturers talk about setting QPI to a certain voltage they are talking about QPI/DRAM which is what ASUS and possibly other manufacturers refer to as CPU VTT on an EVGA board, QPI PLL will have no direct effect on memory, CPU VTT and vDimm are the important voltages for memory. I doubt this will help your missing memory issue as it seems its related more to slot 1/Channel A than voltages. I think your conclusions are pretty close, going by what you report it looks like 1 stick is faulty and possibly 1 memory slot or it may be the CPU needs reseated or its even possible that Channel A is faulty on the CPU (this would be very rare). EDIT i assumed that all your testing would have been done at stock (stock being AUTO for Memory frequency which should give you a memory speed of either DDR3 1066 or DDR3 1333) as it should be the first thing you do when there is a problem but if you were not testing at stock do as KMoore suggested, if these problems dont occur at stock but do when at DDR3 2000

KMoore, I am running at stock now with no difference whatsoever. I think that one stick of RAM is dead and I suspect that first slot on the mobo has some issue since whichever stick of RAM i put there it won't post.

MOLTENLAVA, thank you!
I indeed did the testing on OCed system and then on stock. System has been stable both ways except for the RAM not being all there. I've pretty much reseated all the ram but no difference. I really think that one stick that used to be in slot one is bad because if I put it in slot 3 or 5 it instantly drops the memory count to 2GB. No matter if I have the first slot populated it is 4GB at best. Like the first slot wasn't even there!

I recently had a similar issue with memory disappearing. I had only 2GB show up out of 6GB. I found that if I reflashed the BIOS it all came back, no settings changes. Not sure why this helped, but voltage settings and everything did not help, but reflashing BIOS did. If you decide to reflash BIOS, don't use a numbered version, use something like SZ2Z.

You can use mem test 86, Corsair is good about RMAing, but not near as good as EVGA, When I had a Issue with Corsair, I RMAed, and bought a pair of Muskin redlines to get me by untill my Dmenator GT's came back, I was so impresed with the redlines, I kept them and just added the returned ram to my other system. Take all your mem out of your system and place a known good stick in the first red slot. Corsair usualy wants to replace the compleat kit, not just the bad stick, ( they are matched )

Difrent Bios's had a difrent Vtt base, so your total Vtt may be lower with some BIOS's than with others, and the IMC inside the CPU may need more VTT to properly register all three chanels, ( some are weaker than others, ) but this is just one posability, as there are a # of things than can cause memory to not register, everything from the IMC , CPU, Cpu socket, traces on board, memory sockets, memory controller chip on the ram, the memory chips themselfves, or the voltages and curent of the circuit. even the timeings, as they are the max time before a error is reported. Incresing or lengithing the time allows more time before a fail is reported.

I have 2 good sticks and one bad. The bad stick was in memory slot 1 and the 2 good sticks were in 3 and 5. with all 3 sticks populated 1, 3, 5 I have 4GB in Bios installed and windows sees 6GB but only 3.99GB are usable. If I take the Bad stick from slot 1 nothing changes except windows now shows 4GB installed and usable. If I exchange the bad stick from slot 1 for any other stick in slot 3 or 5 (take the good out and put the bad stick into its place) I have 2GB in bios installed and windows won't boot up. If I put either of the two good sticks in memory slot 1 system will not post with error sequence 02 EA 01 68 which loops infinitely.

A known good stick in slot 1 should work single channel, and two known good sticks in 1 & 3 should work in Dual channel, ( You may have two problems), with a bad stick of ram just being one of them. Do you have any other memory to test with ? Are you anywhere near Atlanta, I have a 6 Gig kit of patriot I'm not using and a 12G kit of XMS3 I'm not using ?

I know I have problems :-) I think that slot 1 is fried and when it did i fried the stick of RAM that was in it. I can run dual channel in slot 3 and 5 with the other 2 good sticks. At this point i think that channel one is for decorative purposes only. Someone mention that it could also be a faulty CPU or CPU that has not been seated right.........

What if he had set Mem Low gap to 2GB, or 1GB and Virtualization on?

No, I'm asking KMoore. I think either of these will thwart a Windows boot on 2GB.

The only thing with that is that if I put just a single stick of ram in slot 1 the system will not even post. if I put that same stick in slot 3 or 5 system will post no problem.

Damn, I just read it recently, but could not find it. It was a post (by MoltenLava I think) that recommended he reseat his memory while sliding the memory back and forth in the slot as much as possible, and it fixed it for somebody. I recorded all the other memory prob threads with this issue lately, in order of reply dates, so you might want to read last first:
Problem 6.00GB = 1.99GB usable? Windows 7 x64 Ultimate
Disappearing Ram...
6GB ( 3.99GB usable) HELP!
3.99GB Usuable with 4.0GHz OC and Stock it shows full 6GB RAM
3.99GB usable
E758 All Ram Not Recognized Issue
This is a very common prob right now.
Thanks man, I appreciate the info! I was reading some of those earlier. It puzzles me that windows see all 6GB installed but only 3.99GB usable but BIOS only sees 4GB. I really think that one of the sticks is bad for all the reasons I stated earlier. I will try wiggle the RAM and re-seat the CPU tomorrow. It's a quite a procedure due to my watercooling. I will see if this makes any difference. All I want to know is if everything fails tomorrow whether or not I need to RMA the board. If so will I get the E759 back or something else???

I can confirm that this truly is an excellent thread. I used some of the techniques described by others and what do you know - I got the the memory slot number one working! One stick of RAM is still KIA but at least I don't have to RMA the board or CPU!!!

It's moot, but if you fixed it with that method, then you either had a bad connector connection on your RAM, or shorting out something in your RAM or connector (or the other possibility below, bad ram contacts). Either way has a rather high likelihood of damaging your RAM stick. That brings me to another point, why are so many ppls having this prob and solution lately? I'm not going to blame EVGA yet bc it could be in the manufacture of the RAM - either the contacts are out of place a little bit, or the board length in the slot is short. Of course the other possibility is the mobo connectors, which seems much more likely considering in about 50% of the complaints they have had trouble with only slot #1. I wonder how many ppls would have troubles with the other slots (2, 4, and 6) if they were using all six. Many ppls might have bad memory expansion slots and just don't know it.

Well said Halloween. I did take your advice and carefully read that thread. Although my problem was a little different, overclocking or not I had only 4GB of RAM available. I was also on the Bios that the board shipped with and I have never flushed it to a different one. Similarities were there so I decided to give it a go. So this is what I did: 1. I took of the waterblock to ensure it was not screwed on too tight. It was way too tight, I had imprint of the socket's bracket indented into the bottom of the block. 2. I took out the CPU and inspected the socket's pins. I kid you not, I was there looking through magnifying glass like Sherlock Holmes! No pins were bent. 3. Put the CPU back and insured that it's properly seated. Push it away from the memory sockets a I were closing the socket's latch. 4. Pushed the actual RAM sticks into the sockets so hard and wiggled them side to side as I were doing it so I had imprints of the memory's heatsinks on my finger tips. Somehow it worked so the socket one is back in action but one of the RAM is dead. I can boot on single stick or two but if I put all 3 (the third being the bad one) I have instant reboot on windows load screen. My guess is exactly what you've said earlier - bad memory connection on slot one. Either I didn't seated the memory correctly or it doesn't align as it should. The point being is that I must have fried one stick due to that but luckily not the slot. For all the people out there having trouble, make sure that the RAM is all the way in the socket, press it hard in there. I will see how the rig behaves after I get my replacement memory in few weeks. Thank you to everybody who replied to my thread for their time and their help.

I had exactly the same problem with a brand new E760. 6GB DDR3 installed, BIOS showed 4 and Win 7 showed 6 with 3.99 usable. BIOS flash made no differnce. Tried each individual RAM slot one stick at a time. Also tried using a known good 6GB Dominator DDR3 1866 Corsair Kit. Slot 3 was hosed. Just RMA'd board.
I've seen a comment in another thread in this forum that advised if the BIOS shows less RAM than you have installed then it's likely the board. Turned out to be true in my case.

its a common problem with overclocking,
1st met it with asus board, when oced to 4,2 ghz and set ram to 1600 or 2000 it only show 4gb instead of 6. with ram set to 1200 it was ok. same with default settings.
its because some of cpus have diferent ram multipliers and setting ram speed to over 1333 causes errors and memory losses
