Computer crashes without BSOD when using 8gb of ram but perfectly fine at 4 gb.

jslstyle · May 22, 2014

My ram is g.skill ripjawX F3-12800CL9D-8GBXL (2x 4 gb kit)
my mobo is msi 970A G46 with amd fx- 6300 cpu running windows 7 ultimate 64bit.

It appears that whenever I put in a specific ram in, it would randomly crash without bsod and stall at black screen. (whether it is in dual channel are put in or just single.)

I've tried running memory diagnostic with what is believed to be a faulty ram but results showed no errors.

My bios setting is set to 1.507V with 9-9-9-24-2T setting and was never overclocked.

What would be the cause of the crashes? I currently pulled the faulty one out and everything runs fine.

Event viewer just shows event id 41.

Try raising DRAM voltage to 1.55 if still problems raise the CPU/NB voltage + 0.07 (that's your MC (memory controller) voltage

Tradesman1 :

Currently my cpu/nb voltage is set to auto. Which voltage should I set to from the beginning?
Wouldn't 1.55V damage my ram? stock settings show 1.5V.

Also, I have no intention to overclock my computer, just want it to work with full 8 gb of ram.

No danger, try DRAM voltage at 1.55 and try CPU/NB voltage initially at 1.175

jslstyle · May 22, 2014

Tradesman1 :

So far, with just DRAM to 1.55V, crashes persist.

With DRAM to 1.55V and cpu/nb voltage to 1.17250 V (couldn't find a setting for 1.175), crashes persist.

I've been increasing the cpu/nb voltage to the next available setting, and so far I'm at approximately 1.195 V. (the setting before this one crashed. )

What would be the max voltage I should go if crashes persist?

Tradesman1 · May 22, 2014

Go ahead and jump to 1.25 (some have to go even much higher), but if stable there can then lower gradually while maintaining stability, the voltages are safe

Tradesman1 :

With DRAM AT 1.55V and cpu/nb voltage at 1.25V, computer still crashes.
Should I raise it more or lower it down?

What slots are the sticks in from the CPU - if in 1-3 then try in 2-4 or vice versa....Might also try in 1-2 or 3-4 and see what it does that way

jslstyle · May 22, 2014

Tradesman1 :

It's in 2-4 dual channel slots. (The problematic ram in 4th slot)
My mobo only offers dual channel in 2-4 slot.

Tradesman1 · May 22, 2014

Should be available in 1-3, give that a try and see

jslstyle · May 22, 2014

Tradesman1 :

yeap, 1-3 gives dual ch.
However, 1-3 or 2-4 both causes crashes with DRAM 1.55 and cpu/nb 1.25V

Tradesman1 · May 22, 2014

How about trying CPU/NB at 1.3 with the sticks in 1-3

Tradesman1 :

Hi, Tradesman1.

From my last post, I thought I'd try memtest through usb drive (my rig has no optical drive)
Anyhow, with both ram sticks in it passed 1 but soon froze.
I tried to do the test again but it kept freezing soon after ( can't even finish 1 pass like it did before).

I tried singling out the rams.
I ran the test again with only the ram that i believe is problematic and memtest would constantly freeze in either test # 5 or test #7. Sometimes it would just restart the comp etc.

I'm currently testing the remaining ram that has no problems and memtest shows no signs of error or freezing.

Should I just conclude that one of the ram is faulty and ask for RMA ?

Update:
for some reason, the ram that didn't cause problem that's in the 4th slot now shows 4-5-5-5-11clk settings despite bios' 9-9-9-24 setting but returns to 9-9-9-24 setting when moved to 2nd slot.

Feeling that something was off, switched the ram with the problematic one and it displays 9-9-9-24 in 4th slot. Also memtest runs smoothly on it now, already passing 1 run and currently testing a second run.

Also, it still crashes with cpu-nb at 1.3v in both 1-3 and 2-4.

I decided to clean install windows 7 to rule out if it was a software issue.
After doing so, it's been able to run primetest95 no problem unlike instant freeze from before.
I think overall my computer's stability has increased.
Not sure if this is a 100% fix but so far so good.

Glad to hear, keep us updated

Tradesman1 :

Hey Tradesman1,

Unfortunate news. After windows update and what not, the problem as resurfaced once again...
Seeing how sometimes even during memtest computer freezes eliminates os being faulty.
What would be the cause?

Tradesman1 · May 25, 2014

Can you lay your hands on any similar DRAM to test with, if same with other DRAM may be mobo or a slot

jslstyle · May 25, 2014

Tradesman1 :

Unfortunately Not. This is my first built computer so I don't have any other slots or rams to test it with.
Few things I noticed:
1. Each slot somehow shows different ram setting during memtest.
2. Even though bios is set to 9-9-9-24, 4th slot ram automatically switches to 4-5-5-11 when single specific ram is put into the rig.
3. I will be running memtest over night with both rams put in 2-4. I will post an update tomorrow.

Thank you for guiding me through this. Hope we find a solution soon.

Sounds like there may be a problem w/ the mobo if showing bad info in the BIOS, might contact your mobo maker and see if this is a common problem, they might have a BIOS 'fix' if it is

Computer crashes without BSOD when using 8gb of ram but perfectly fine at 4 gb.
