I installed 2 set Corsair CMT16GX3M4X2133C9 in in all 8 slots. But only 16gb is recognized in windows and in BIOS.
I use some program to check that.....only A1,A2,B1,B2 is running........
I try to remove and restall the ram many time..but the result is same....
Finally I have traced some problem on C2,D1,D2 ram slots.....
If I install the ram in A1,A2,B1,B2,C1......that is ok....20gb is recognized Windows and bios show.
but try to install ram in C2/D1/D2 ram slots.............only 16gb can be recognized in windows and in BIOS

I am sure C1, D2 are working normally...
Before I got 2 set Corsair CMT16GX3M4X2133C9. I install samsung 1333 4G ram *4 in A1,B1,C1,D1.....Evenything is fine.

should i rma my R4E?

Sorry for my poor english.....

Sure probably I use just the header "Rampage series M/B to post all because I have R3E and now R4E is new today. so im not just crying about what went wrong im just celebrating what did work out and that im very thankful for the advise and the wealth of support here . I will take the time to learn more about the "offical rules". honestly im 39 and in this last couple of days i have posted more than anyother forum in my entire life. I dont do these forums really to tell you the truth, I dont facebook or TWAT.

Please take one stick of ram that you are confident is working 100% and run memtest in each of the memory slots. Use only the one stick of ram please.

I am trying to determine if you have a memory slot that is playing up.

definitely a reseating of cpu in socket is to be tried as well as reseat of rams

Try this, not sure if this will work, but I gave it some thought when I was building my computer when I was using two different sets of memory of the same exact memory.

Seperate out your ram from the kits it came from. Check the serial numbers of each kit. With Corsairs, each set should have a shared serial code or some sort whcih is only unique for that one kit. I know because I'm using 2 exact same 3x2GB Dominator GT kits and they have different kit numbers but their the exact same memory. When you have all 8 sticks seperated into the 2 different kits, try installing your memory in this configuration listed in my diagram below. I'm running my memory like this: _ 1 2 _ CPU _ 2 1 _ (and I have 2 sticks are spare)


1 set of 4 sticks on all the red Sockets (this will be noted at "1" in the diagram below)
2nd set of 4 sticks on the black sockets (this will be noted at "2" in the diagram below)

It should look like this:
1 2 1 2 CPU 2 1 2 1
Make sure the EZ_PLUG is plugged in for the extra power, it's the 4pin connector.

When I was building my computer I knew I might have a memory issue if I just loaded one side of the board with a full kit andjust take 1 from the other kit. So I balanced out the 6 sticks I had and only took 2 from each kit even though they were the same memory, but since their from two different kits, I knew I should try seperating each kit to keep within it's own channels. So I did mine in a: _ 1 2 _ CPU _ 2 1 _ setup

I know this sounds silly because, if you buy 2 kits of the exact same memory they should technically all run without any issues, but the truth of the matter is, each kit is different and they were only tested to work as the kit came as.

I am running 2 sets of gt2133c9 x4 for total of 8 dimms 32Gb matched 4 on 1 side and matched 4 on the other. I didnt do the mem dance. U can see my other post it has a cpuz photo but i dont think its showing the info to confirm maybe. but im telling the truth i haver the32Gb in xmp mode per cpuz screenshot

Can you also take 1 stick of ram, and test each slot?

I looks like you have faulty ram slots, could you confirm that you have removed and then reseated your CPU please.

btw are u using the x-socket? could u maybe have scratched the pcb slightly when switching to x socket back plate? just guessin

Now this post is for people that have the ram issue and may have the same problem, the direct problem can be see buy removing the CPU and checking the impression on the back of the CPU for pins that are not pressing in the rite spots and by your opinion to either try to fix it or send it back for a replacement
