could unstable wattage be causing blue screening ?

[SagginJones]

with all of these blue screens talking about code 124 or something and pointing at amd and north bridge could it be that the amd 125W cpus are not getting stable wattage from most boards ?

I'm having a problem like this and msi redone my boards supported cpu's to 95w cpu's when it was 125w

my specs

motherboard - msi 760gm-p34
cpu - amd fx 4130
psu - xtreme gear 600w atx model xg-h600

Yes, unstable voltages are the main culprit of blue screens, as well as memory allocation errors. Check your voltage when under load as most cheaper boards have a lot of vdroop which will lower the voltage under load. my M5A78 board (760g) has a lot. if i set it to 1.33v it will drop to 1.27 under load and blue screen. Either set load line calibration in the BIOS or up the Vcore a tiny amount until it runs stable. (0.0125 at a time, just watch out for socket temps.)

Do you understand the BIOS settings? there can be a fair variance in the terminology used. Basically you want to keep the vcore as stable as possible while under load. 1.3125 steady is better than 1.37 dropping to 1.30 under load. My with most of my AMD boards i manually set the vcore to the VID of the chip and enable load line calibration (normally a percentage) at 75% and it limits vdroop at expense of temps.

Thanks for your reply. I understand what your saying mostly I'm just unsure how to actually go about changing and testing the changed settings and stuff. I don't know if I would know enough about what I'm doing to not melt my cpu or something. lol

Nah, you won't do any damage, they have a thermal shutdown and throttling mechanism inbuilt so you don't fry your cpu. The best way to test for stability is to download program called prime95 http://files.extremeoverclocking.com/file.php?f=205 and run a stability test for an hour or two. If you are blue screening you will no doubt fail prime.

Use a program called aida64 or cpuid to monitor vcore while under load as you will find that it will be fluctuating. If you need any help feel free to ask questions and ill give you a more detailed walkthrough.

Also try disabling turbo core in the bios as that can sometimes mess with stability.

 

[r_ward_87]

A good start is to download cpuid hwmonitor http://www.cpuid.com/softwares/hwmonitor.html and Prime95 http://www.mersenne.org/download/ and watch the vcore under load and tell us what you have.

I have also noticed in your report that the fatal error was from your northbridge, which could also be a memory error or gpu driver error.
The cache hierarchy error in your corrected error section normally means one of your cores has posted an error (usually due to unstable voltage). I would also check your ram for errors as it could likely be the culprit.

 

[SagginJones]

ok thanks for the help. I'll do some of that and check back.

 

[SagginJones]

I haven't had time to do any of that yet but I did disable turbo core and quite and cool like people where suggesting. I haven't had time to test it yet though. and I wasn't able to locate where you change vcore settings ? but I think I did see it was set to default at 1.160v.

 

[SagginJones]

I still haven't ran the tests but I tested with quite and cool and turbo core disabled. no change in the problem. but here's a little more info till I run more tests.
Seems like its crashing with games mostly but has crashed playing youtube videos.

here are a few more reports its giving.
