Windows 10 x64 BSODs - WinMemTest shows RAM errors

joshreynoldaraujo · Oct 19, 2018

System -
AMD Ryzen 3 1200 (STOCK/NO OC)
8GB 2600MHz DDR4 RAM
MSI A320 Motherboard
GTX 970
550W PSU

Symptoms -
1. BSODs
Saw 4-5 in a few hours each time with a different error message - SYSTEM_SERVICE_EXCEPTION
REGISTRY_FILTER_DRIVER_EXCEPTION
PAGE_FAULT_IN_NON_PAGE_AREA
KERNAL_SECURITY_CHECK_FAILURE

BSODs have happened -
a. Downloading BF4 from Origin, Copying 38GB of data from external drive to primary drive (where C Drive is). Was on browser at wallpaperswide.com when BSOD occured.
b. Opened Origin and attempted to redownload BF4. BSOD occured.
c. Editing photo on PS CC. PS was open for 40-45 min without issue before BSOD occured.
d. Ran full system scan in cmd - sfc /scannow command. BSOD occured 5 minutes into scan.

2. Did a Windows Memory Diagnostic thinking it might be a RAM problem
Showed "Hardware problems were detected" a minute into the test. When Windows booted it showed me a similar message.

3. Thinking back, I had noticed issues prior to BSOD, Chrome would randomly close/crash with no error message. Sometimes when I'd start up a game the splash screen would show and then nothing. Could be a sign of RAM failure?

4. Prime95
Could not even begin the test. Shows "Rounding off error. Rounding off was 0.49999 expected 0.4"

5. OHM and AMD Ryzen Master show no problems with CPU - voltage is stock, temperatures are all low (right now shows 44.3 Celcius with chrome, notepad, explorer open and Steam, GOG and Origin running in Background without downloads)

6. AMD Ryzen Master shows Memory Clock under Memory Control as 1200MHz. And shows Ryzen 3 1200 moving between 3.1GHz and occasionally to 3.45GHz (is this normal as 1200 is supposed to have 3.1 base and 3.4 boost)

System is 6-7 months old and has run like a dream so far without any issues.

Kindly advise, getting very worried.

Have U changed anything in BIOS recently.

Try clearing BIOS or updating it and use stock RAM speeds.

Also check if your windows partition is corrupted and try updating windows.

this is a single module ram do as suggest put bios back to default and ram at default speed then use memtest to check ram if you have error on it rma and if you could get a dual set .

joshreynoldaraujo · Oct 19, 2018

I haven't changed anything in bios besides boot order. I haven't overclocked anything neither do I know how.
Does it mean my ram is running at 1200?
Will try switching ram slots

scout_03 · Oct 19, 2018

use cpu-z spd memory tab to see ram speed and multiply by 2 will give the speed of ram .

nitron64 · Oct 19, 2018

It could be the Boot drive also. Use checkdsk or other utilities then check the drive and partition records.

The Registry, Page fault and kernel errors are all related to corrupted windows files. use sfc /scannow or try a fresh install with only essential devices connected .

scout_03 :

CPU-Z shows DDR4 RAM (2400MHz) clocked at 1200 MHz.

Bios is stock and unaltered since purchase.

Prime95 is still showing a rounding error, what could that signify?

nitron64 · Oct 20, 2018

Take a look at this maybe it'll help:

BTW, is my ryzen voltage and peak speed supposed to fluctuate?
I see voltage moving between 0.85 to 1.26 volts.
And peak speed moving between 2.5ghz and 3.45 ghz

nitron64 · Oct 20, 2018

I'M not sure.

Intel has speed step which lowers the clock speed of CPU to save power but the voltages always remain constant. Don't know if AMD has something like that.

But looks like the motherboard could be bad and it can't regulate the voltages properly resulting in system instability.

I maybe wrong about this. Maybe someone can chime in on this.

nitron64 :

Looked it up in detail, apparently Ryzen CPUs have something called XFR that alters the core clock to match demand, also overlocking the CPU to beyond boost values (in my case 3.45GHz). This also changes the CPU voltage and is apparently normal.

Is there anyway I can isolate the problem being either HDD or RAM?
WinMemDiagnostic shows problems with my RAM, but is it possible the HDD is getting buggered also? It's a loan piece from my previous build and is now pushing SEVEN years old. (1TB WD Green)

I have 3 other HDDs in the PC (2TB, 3TB, 500GB) but all 60-80% full up, making loading windows on them for a test quite difficult.

I tried CHKDSK /f /r but it got stuck at 11% and wouldn't budge for over an hour, ended up force shutting it down. (All other drives were disconnected, only the primary 1 TB with Windows was plugged into the motherboard)

nitron64 · Oct 20, 2018

Use crystalmark or any other utility to check the smart status of the HDD. I have had several drives die on me without any sign of warnings.

As for ram, you will have to get your hands on a spare ram. Maybe borrow one from your friends.

What I would've done to test ram is run memtest on Ubuntu live on usb or Ultimate boot disk(UBCD) to eliminate HDD and windows as the culprit.

Hope this helps.

P.S. - Try updating your bios for better compatibility. Ryzen platform is pretty finicky about ram speeds.

scout_03 · Oct 20, 2018

it stop at 11% so use is maker software to test it on both short and long if he fail any and still under warranty ask rma .

thanoobdog2 · Jan 7, 2019

90% chance that is a RAM problem. 8% that it is the motherboard and 2% that is the cpu (faulty MCI/Cache) If you don't have another ram get it on a computer store and they can test some other spare sticks that they have for a small fee. If checkdsk and scannow run without issues, your disk and windows are alright even if the ram is bad.
