Z87X-UD5H 4 DIMMs and BIOS F8c

[cactusweasel]

Hi there,

I know there are a lot of threads relating to BSODs and crashes etc when using 4 sticks of ram but I couldn't find one specifically for the UD5H.

I just wanted to ask, has anyone else updated to beta BIOS F8c and tried again with 4 sticks of ram?  I've been running all day with my 4 sticks of Kingston Hyper-X (only had 2 in up to now) and so far I've not had any issues, despite several hours of Kerbal Space Program, which consistently crashed or BSOD'ed with previous BIOSes.  All BIOS settings are default (apart from on board GPU disabled) and ram running at 1600mhz@1.5v 9-9-9-24.

The only thing I've done since was I swapped out my Xonar D2X card for a new Soundblaster ZxR but given the amount of people with the issues, I doubt that would have had any effect.

Anyone else having luck?

Have had 4 sticks of Gskill Trident X, (32GB), with both BIOS F7 and 8c with no problems. Board originally had F3 and also had no problem but I updated to F7 before loading Win 7 X64.

I had random BSODs about 2 or 3 times per day with bios F7. No memtest86 errors at all (tested thoroughly). Gigabyte support suggested that I used F8a, so I did, but that didn't solve the problem. I decided I'd try to learn to live with the BSODs, after all, this build boots up in seconds and I'd just have to save my work more frequently. Eventually it got annoying so I decided to use only 2 of my 4 RAM sticks. With 2 sticks, the system was 100% stable and there's no noticeable performance difference between using 32Gb and 16Gb for the type of work that I do (photoshop). I did increase the CPU System Agent Voltage by 0,2v or something like that cause I read somewhere that using 4 sticks could benefit of doing so.

I have a 4770K, the Z87X-UD5H and 32Gb of TridentX at 2400Mhz CL10.

So you say that there's a new beta BIOS F8c. Let me ask something, did you have problems with F8a and now with F8c they're solved? That would be fenomenal.

BAD NEWS!

Flashed F8c yesterday and popped in my 2 unused sticks. Bsod 4 hours later. I then tried using only 3 DIMMs only to get another BSOD doing the most random task. So now I'm back to my 100% stable system by using 2 DIMMs in dual channel for a total of 16Gb.

Summing up:
More than 2 DIMMs causes BSODs with BIOS F7, F8a and F8c.

We're wasting our time. To solve this issue, first Gigabyte have to be able to replicate the problem, which they haven't been so far. In the meantime it's absurd to expect that all these new BIOS versions, that usually only contain compatibility updates for the new processors that come out, will magically solve a problem that they haven't actively worked on.

Either this problem is unsolvable from the firmware side and they're hiding their acceptance of of it, or this problem is so random and unreplicable that we're just left to use only 2 dimms and to wait for when it's worth it to upgrade and not buy gigabyte again out of superstition (cause, let's face it, these are generally good boards).
