Hi everyone,

I was wondering if anyone could help or even if anyone has experienced the same problem...

I bought and built a PC from here around Xmas time 2012, using a Gigabyte Z77X-UP4 TH Intel Z77 (Socket 1155) DDR3 Motherboard (https://www.overclockers.co.uk/showproduct.php?prodid=MB-405-GI) and Patriot Viper "Black Mamba" Generation 3 16GB (2x8GB) DDR3 PC3-12800C9 1600MHz Dual Channel kit (https://www.overclockers.co.uk/showproduct.php?prodid=MY-059-PA).

Everything seemed to be going well for the first lot of months, but then I kept getting random freezes and lockups, and then BSOD complaining that there was something wrong with my memory (PAGE_FAULT_IN_NONPAGED_AREA, SYSTEM_SERVICE_EXCEPTION). Turns out after running memtest86 for half a day that one of my memory sticks was corrupted - I had my two sticks in the DDR3_1 and DDR3_2 of my motherboard, using the Profile1 (X.M.P settings) and everything else to Auto in the BIOS, and the stick that was in the DDR3_1 slot was the one with errors.

I ended up ordering another set of the same memory, as I couldn't wait until the current set were replaced (I needed my PC for work and had no other PC/laptop available!).

Put the new memory in, ran memtest86 for just over half a day and it reported no problems... until a few days later that I started getting the same BSOD and whatnot, tested the memory and it said it had faults! Funny enough, it was the stick that had been in the DDR3_1 slot again!

Normally I would just assume that I was unlucky and got a bad batch of memory, but what are the chances of ordering memory near 6 months apart and the same problem with the same slot on the motherboard?
The other unusual thing I have noticed is when I placed a working memory stick in slot DDR3_1 (just the one stick, so single channel) and ran memtest86 with it it was reporting the CAS settings as being 6-6-6-20, 800Mhz? Yet putting the same stick in DDR3_2 it reported the correct CAS settings, as seen in the BIOS and using CPU-Z :(

Has anyone else experienced any similar problems with this motherboard? I'm starting to wonder now if the memory in fact was fine at some point, and it's my motherboard that is somehow frying them!!!
 
Have you tested each stick individually in the different available RAM slots? It does seem a bit fishy for two sticks to go bad in the same slot.

I'm not sure how the slots on the board are labelled, but shouldn't your RAM go in slots 1 and 3 to activate dual channel mode?
 
Yeah tried each memory stick by themselves to figure out which was faulty - I didn't have to do much testing, about 5 minutes of Borderlands 2 and I was being bombarded with errors :p games would go straight to BSOD - if not, explorer would keep crashing, programs would quit before eventually failing altogether

My slots are a bit funny - from left to right, they are labelled
DDR3_4, DDR3_2, DDR3_3, DDR3_1, with DDR3_4 & DDR3_2 being Channel A and the others being Channel B.

The manual says that (taken from the manual on the Gigabyte website)
"For optimum performance, when enabling Dual Channel mode with two memory modules, we recommend that you install them in the DDR3_1 and DDR3_2 sockets"

I thought it was unusual as well, but I can't think of any other reason why the memory would go faulty :confused:
 
From CPU sockt to front of case,its empty ram slot,install,empty ram slot,install.

Enable xmp and manually set CPU/vtt to 1.10v then see if its any better xmp won't set that setting and with 16gb you'll need more than stock 1.05v

Also flash to latest final f9 BIOS it will improve stability esp ram
 
Motherboard came with BIOS f9 installed, memory is set to XMP 1.3, and according to the BIOS 1.5v (all the settings are set to Auto)

I actually thought it was some BIOS setting that was off but I couldn't understand how it was affect one stick of memory and not the other :confused:

At the moment I have the two working sticks of memory in the other slots, so from CPU to front of case its now
installed ram, empty ram, installed ram, empty ram

Going to give it a bit then try running IntelBurnTest to see how it goes - with the faulty ram installed, it only took a few minutes before it would crash so hopefully won't have to wait to long to find out :P
