Troubleshooting Bluescreening PC - Memtest Errors

[Devastator0]

Hi LTT Forum brainstrust, I need some help.

 

I have a PC that has, for some time, been experiencing random bluescreening issues and I'm finally being able to get around to trying to determine what the problem is. As one of the first steps in doing that, I wanted to run a memtest scan on the machine and if you refer to the attached image on this post, you'll see the results. I'm not too familiar with the results of it but I was wondering if, based on the screenshot I've attached, anyone can tell me what could be the issue here. Not sure if it's RAM or CPU (I think CPU because it specifically mentions "CPU: 4" on the error line).

 

Specs of PC are as follows:

 

PSU: Corsair SF600 SFX 80 PLUS Gold 600W

Mobo: Asus ROG-STRIX-H370-I-GAMING

CPU: Intel Core i5 8400

RAM: Corsair Vengeance LPX CMK16GX4M2A2400C16 16GB (2x8GB) DDR4

SSD: Samsung 960 EVO NVMe M.2 500GB

GPU: Asus Strix 1060 6GB

 

If anyone who is more versed in interpreting this results could give me some advice/direction, I would very much appreciate it!

 

Cheers!

Not exactly. The memory stress test is split up so 1/6th of the RAM runs on each of the CPU cores, and the RAM that error-ed on core 4. If it consistently happens on core 4 I'd be suspecting the CPU, but if you run it again and it ends up on a different core (this is more likely) it sounds like your RAM or IMC is bad, more likely the RAM than anything.

Hmmmm, interesting. The PC is currently running it's 3rd pass, but the 2nd pass did produce a failure on Core 4 as well. I'm letting the other 2 passes complete to see if it does the same thing. Annoying if it's the CPU as I'd need to hunt down another one of these 8th Gen Intel chips.

Test 1 by 1 RAM module.

Yeah, that's what I plan to do. I need to pull the CPU cooler off to swap out the RAM (tight fitting machine lol)

So to close off this post, I ended up getting around to testing 1 RAM stick at a time and determined that one of them was badly faulty. When I ran MemTest with just that stick in, it threw a whole bunch of errors. Ordered a new kit which should get this all sorted out. Cheers to everyone who has posted!
