Gigabyte Z87 mobos freeze when using 4 healthy sticks of RAM

[flexmanta]

Hello

This appears to be a widespread problem generally (not only to hackintosh).

Many users have reported having random system crashes when populating all ram slots in their GA-Z87 mother boards. I have a Z87X-UD5H with a 4x8Gb ram kit and I'm having this problem:

-When using 4 sticks of ram, the system freezes randomly a couple times per day.
-Using one, two or even three sticks, solves the problem.
-Ram has been tested with memtest86 and with no errors.
-My ram is 32Gb of g.skill at 2400Mhz 1.65v, but problems have been reported with sticks of other brands and specs.
-RMA'ing the RAM or swapping the PSU has not fixed the problem for the majority of people with this problem.
-Lowering RAM Speed, relaxing timings and or increasing DRAM voltage has also not fixed the problem.


Gigabyte has suggested solutions such as disabling some C-State options in the bios, which I'm currently testing.

Anyone else having this problem here? (Any z87 mobo freezing randomly when using all RAM slots with perfectly healthy RAM)

I have the same problem with my GA-Z87X-UD4H with Kigston hyperx 1600 4X4GB.
Ii'll try to ues less than 4 sticks to see if there is any changes

I had some random freezes in OS X but didn't know it might be related to RAM. I might give it a shot using less than 4 sticks. I'm not sure if it freezes in Windows also, haven't tested it much.

I am having the same issue, there were random freezes when using all 4 slots, but when I am using only 3 slots, there are no freezes. does it work when turn off the C-State?

Thanks

I'm having the same issues, and it DOES lock up windows also, causes random bsods...
took off 2 sticks and it's been 12hrs without any issues.
Shame on GB.

Used the computer extensively for 48hrs no issues. putting on more stick will cause system instability.

Have you found a solution? I think I have the same issue. I've tried to update to the latest Beta Bios F7b built in late October but that didn't fix it. I'm guessing this might be some hardware design defect that can't be fixed in Bios?

Experienced a similar problem (BSOD on Win and freezes on OSX 10.9.1) when I tried to add 2 more sticks (2 x 4GB DDR3 1600) of memory to an established system. The advanced memory setting in my BIOS was "Profile 1" in XMP in order to get the 1600 memory speed.

I had no problem when I added only one of the additional sticks in either of the available slots. But, the addition of the 4th stick caused problems.

Since I knew that both new sticks were good, I tried setting the XMP to "disabled" thus setting the BIOS memory back to it's default 1333 speed. After a restart and shut down, I added both new sticks at the default 1333 speed in BIOS. No problems with 4 sticks.

Since Win and OS X ran for 3 days without problems, I reset the XMP to "profile 1" to get the speed of the memory up to 1600 and found that there were no problems with all 4 sticks installed. Have been problem free for over a week.

Interesting.

I have some few random freezes with me Z87X-UD3H and 4x4GB Kingston HyperX.

I am using memory profile 1 running at 1600 MHz, everything else is stock, and BIOS F7.

Initially I got better stability after the latest bios revision.

My system fully works, sleep, shutdown, reboot.... So far I'm happy with it.

Perhaps I will change to 2x8GB in the near future.

Hi,

in a office Hackintosh that i was setting up, this freezing problem persisted, no matter what card you took out or anything. The MoBo is a Gigabyte GA-Z87X-OC with 4 ripjawz 8 gig sticks at 1333 mhz, without xmp.
With the BIOS version the board originally shipped with, this problem was horrendous. It would freeze every time after just a few minutes. Upgrading the BIOS to the latest version (F7D) has reduced but not eliminated the problem. Now i just have to decide between 24 gigs of ram running at half the bandwidth or 16 gigs at full speed
The Hackintosh is used in a Professional-Audio environment, why it is crucial that the system is absolutely rock-solid.
So i guess i'll just take out one stick for now and see if the problem will ever appear again (whats maybe of minor importance is that the system is running a quad channel kit, and not two dual channel ones)

So maybe any tips on how to properly stress-test this thing?

Greetings, entro

EDIT: Nope, still freezed could it be a ram-leak that caused the freezing? because when i took a look at the frozen screen just a sec ago, all the ram was filled up to the max

Hello,
GA-Z87X-UD5H with 16GB (4 sticks of corsair CMZ8GX3M2A1600C9)
Windows7 on HDD / OS X 10.9.1 SSD

Before full OS X deployment, decided to test stability of CPU-RAM-GPU aka "system" in windows because more tools/support available...
with initial BIOS it was a nightmare as other ppl mentioned: even 4 BSOD /day

Updated BIOS to F7: Still BSOD but not so fast
Updated BIOS to F8: After 2 BIOS revisions i was confident that the problem was gone
so tested with latest prime95 all three options:
small fft - 24 hours
in-place large fft -24 hours
blend custom 90% RAM ~12500MB - 24 hours
LinX 90% ram -24 hours PASS
ALL those tests sequential with NO errors
concluded: CPU = rock solid after stress with no errors
yes, you guessed right! BSOD the day after in simple use, folder opening, browser etc.
BSOD again aaaaaaaand again next day.
Was time to bring up memtest86+
Tests with memtest86+:
day1: found error on test5 after 4 hours
day2: ran 24 hours no errors
day3: real usage in windows: BSOD after couple hours of light usage
day4: ran memtest again: after 5 hours error on test5

Now i've flashed beta bios F9a and have 2 days in windows without BSOD (yet)
also ran 8 hrs of memtest86+ only on test #5 that failed, and no errors
Looks that something has changed; possibly F9 will be stable for my 4 sticks of RAM?
Hope Gigabyte will fix this shame in F9 final, because i'm tired of testing some new hardware supposed to
be production ready... till then i'm running 10.9.1 on backup system with the SSD installed in z87x system, waiting for A REAL rock solid bios to deliver.

update: 2 weeks (and counting) stable with F9a.
update2: months later... F9a Windows 7 SP1 (rock solid), OS X 10.9.* (production ready, some rare boot freezes i dont even waste my time fixing them)
