Just crashed again....

[KCarney]

Take out all of your RAM, put 3 modules aside. Put 1 module in the slot closest to your processor and run memtest, when finished remove the module and replace with another. Repeat this until you find the chip or chips causing the crash. If none cause a crash fill 2 slots with RAM and begin rotating it until you see a crash. If there are no crashes, fill 3 slots ....etc

Test Progress:
Stick 1 Slot 1 --------No Crash
Stick 2 Slot 1 --------No Crash
Stick 3 Slot 1 --------No Crash
Stick 4 Slot 1 --------No Crash

Stick 2 Slot 2 --------No Crash
Stick 3 Slot 3 --------No Crash
Stick 4 Slot 4 --------No Crash

Stick 1&2 Slot 1&2-----Testing

[KCarney]

Also try

Stick 1 Slot 2
Stick 2 Slot 2
Stick 3 Slot 2
Stick 4 Slot 2

Stick 1 Slot 3
Stick 2 Slot 3
Stick 3 Slot 3
Stick 4 Slot 3

Stick 1 Slot 4
Stick 2 Slot 4
Stick 3 Slot 4
Stick 4 Slot 4

Just curious, and it may help.. Did you purchase any of this RAM recently? And is it all the same brand?

[SulMec]

Nope Bought it all the same time about 4 years ago, its all exactly the same.
Have done:
Stick 1&2 in Slot 1&2
Stick 1-3 in Slot 1-3
Stick 1-4 in Slot 1-4 (Just to make sure it still crashed at 45% and it did)
Stick 2-4 in slot 2-4

Will start on stick 1 in slot 2 now and go through that chain. No crashes except for when 1-4 are in their respective slots.

Stick 1 Slot 2 No Crash
Stick 3 Slot 2 No Crash
Stick 4 Slot 2 No Crash

Stick 1 Slot 3 (336 Errors, No crash)
Stick 2 slot 3 No Crash
Stick 4 Slot 3 No Crash

Stick 1 Slot 4 (171 Errors, No Crash)
Stick 2 Slot 4 No Crash
Stick 3 Slot 4 No Crash

Either I damaged stick 1 or that might be the problem, Seeing if I can crash my computer without Stick 1 in.

[SulMec]

OK, Left out Stick 1 and its still crashing..........

Sadly I believe your issue could possibly be micro-cracks in your motherboard, or possibly something wrong with the physical RAM slots.

Try this..

That is pretty bad news, means more testing lol

try similar tests using slot 2 and 3

[SulMec]

I have noticed that the more RAM I have plugged in, it crashes more often...if i have the minimum then it gets harder to crash it.
Thought I should also add that I ran Prime95 and got: Fatal Error, Worker #2 self-test: Rounding was .4921875 Expected less than .4 Hardware Failure Detected. I ran it again and couldn't get it to detect an error =/. Not being able to replicate is annoying.

It would be easier to replicate if there were some common variable each crash shared, unfortunately that is not yet the case. Are you testing with all unessential hardware devices disconnected? IE; USB peripherals, PCI/PCIe cards, media reader(pluged into USB internally

[SulMec]

Was testing with bare minimums.

[SteelTrepid]

I'm really glad....well not really....that you guys are still going on about this. At least no one has gone crazy yet or smashed anything. While I do want you to figure this out and get it fixed, it is really looking like a pain in the ass.
I keep popping in to see how things are going and to maybe add something to help, buy you guys have just about everything I would have covered. I wish I could help more, but if something pops in my head I will be posting. Good luck!!

[SulMec]

Ya, had to do some stuff today so wasn't able to get the mem tests done gonna start in the morning. Thanks hehe and yeah I have been really tempted a few times to smash things. Wish I just had a replacement for every part in my computer so I could swap out and see if it fixed it. Would be the fastest way haha.
