I have a MB I'm trying to run with 8GB of ram in 4 sockets. These are 2 kits of matched pairs (not a one kit with 4). It is Corsair CMX4GX3M2A1600C9 memory. Bios is ver F8. MB is rev 2.0.
Each of the modules work fine separatly and in pairs, no errors with Memtest86+. When I put in all 4 the machine won't boot at all. I have tried the pairs in different slots. One pair works in every combination (1&3, 1&2, 3&4), the other just works when I put them in slot 1&3, not in 1&2 and 3&4.
I have tried changing the memory frequency and set the voltage to 1.65. Nothing helps when trying to run all 4 modules.
So my questions;
1) Is it impossible to get two pairs of matched pairs to work together ?
2) In this config should the matched pair be in socket 1&2 or1&3 ?
3) Does the differnt behavior of the to pairs indicate anything?

It sounds to me as if one of the modules at least might be faulty. I would suggest downloading and running Memtest86+ and checking one module at a time for at least 10 loops. If any fail they are faulty.

Thanks for your tip. I have tested them with Memtest, but they all pass.
-
Individually?
-
Yes, individually.
Bbut, not 10 full passes on all, but a least 2... I'm redoing it now with 10 passes.
-
You need to do about 10 because often it will pick up the faults on 5 or 7.
-
ok, the two suspected modules are now tested 10+ times - no errors. I'll do the same with the two that seems to work flawlessly.
-
Yes better to test and be 100% sure that all your memory is working flawlessly.

Memtest is not perfect ( can report good memory even if it is bad , i have already found it )
Can you test with another 4 memory sticks ?

No, the machine doesn't get past POST with 4 modules inserted. In my first post is the precise combinations that works and not described
-
Have you tried booting with all four modules installed and set to 1333 in the BIOS? It may not be the memory's problem but just the fact that it is trying to be pushed beyond the JEDEC rated limit.
The other thing to consider is are you running the latest BIOS update?

Yepp, I have tried 1333, 1066 and even 800. At 800 it boots like every third time.

I think F8 is the latest.

Sorry about that strange answer, I misread your question.
No I don't have any other DRR3 modules to try with.

Well even though Memtest says that the modules are ok I still feel that there is no other explanation for the problem except faulty memory. I would advise RMAing it and having it replaced. :-\

Well, what else is new in
gigabyte motherboards????
This motherboard have big problems. I tried most of the recommend memory's and nothing seems to work.
To the Management of gigabyte:
Dear Gigabyte managers I WILL NEVER BUY GIGABYTE'S MOTHERBOARD AGAIN. The support is a piece of crap the answer is always the same. do this, do that, always the same piece of sh*t.
ASUS for sure wil be the next step. f*** GIGABYTE.

I am sorry that you feel this way but airing your grievances on the forum here will not help one bit as I don't suppose anyone from Gigabyte high command ever frequents these lowly pages. You need to write to them directly if you want them to know how you feel. I am afraid that you will find the same sort of response from ASUS also as I help out on their forums and plenty of people feel the same as you, in fact many come over to Gigabyte. But good luck anyway and I hope your next board has less problems for you.

I have RMA'd my memory. Got the new ones today - and they worked perfectly!
Thanks for all your help!!

That's great news even though it took some sorting out we got there in the end. ;D

I know this is an old thread but Im looking for a solution to it myself.
I love Gigabyte boards... Absolutely I do. Ever since I got my first E6300 and the 965p DS3 I have loved them, and the DS3 in particular. I currently own 5 different DS3 boards, one is an AMD based and I found that cool.
Anyway, I am digressing...
I have had some issues with my Asus P7H55 and it shuts down for some reason that I canot work out and so bugger it, Im going back to Gigabyte and then this bloody thing... Well, its seemingly rock solid so far and yet 4GB only being used?
Ok, well before you go about RAM, I must inform you that I am lucky enough to be in a position where I have loads and loads of options. The RAM is good RAM. I am currently using 4 sticks of Kingston HyperX, but OCZ, Corsair, Crucial all show the exact same thing.
The BIOS sees all 4 sticks in, it also tells me that only 2 or the 4 slots are enabled???? - How can I enable teh other 2 then?
Windows ( and Linux ) shoow me that there is 8GB installed but only 4GB is useable, CPUS shows me the info about all 4 sticks.
So why only 4GB?
For the record I do not use any form of 32Bit O/S - its all 64Bit so its not that, but its just as if the Mobo seems to think that.
I was on BIOD F7 and slots 1 and 3 were anabled back then, but upping to F9 and now 10g its slots 1 and 2 that are enabled??? Why sturn off 3 and turn on 2?
Anyway... Anyone have any clues?

Hi and welcome.
The first thing to check is that it isn't Windows stopping it from being used. There is a setting called Maxmem. You can find it in msconfig. Make sure it isn't set to 4GB.
