J'ai acheté un MSI GT60 2PC dominator il y a 2 semaines. J'ai voulu upgrader ma mémoire ce WE, en changeant la barrette de 8Go 1600Mhz CL9 contre 2x4Go 2133Mhz CL11. Le changement de barette mémoire a nécessité le démontage du système de refroidissement, un heatpipe empêchant de retirer la barette. Au passagen j'en ai profité pour remplacer les pâtes thermiques par de la Arctic Silver.
Après changement j'étais plutôt content, car les débits mémoires ont plus que doublé:
Seulement voilà, après 15mn d'utilisation du PC (en mode bureautique), premier plantage. Puis encore un autre et ainsi de suite, en moyenne 15 mn d'utilisation maxi du PC avant plantage.
J'ai d'abord testé la mémoire installée avec Memtest86+ et c'est passé sans aucun soucis:
Puis ayant démonté le système de refroidissement, j'ai voulu testé si celà ne venait pas de là:
- Test du GPU sur unigine Valley: pas de plantage au bout de 10mn de test, la température a baissée de 2°C au max (80°c au lieu de 82°c), pas de baisse de fréquence du GPU
- Test du CPU sous OCCT: je ne l'avais pas testé avant, mais pas d'erreur au bout de 10 mn de burn en large data set, température max de 71°C
- Test du GPU intel HD4600 sous OCCT: j'ai d'abord eu un crash au bout de 5s, mais au deuxième essai, pas de crash et 74°C max
=> le système de refroidissement fonctionne bien et ne semble pas la cause des crash à répétitions.
J'ai fait une analyse des logs par Whocrashed, et il y en a pas mal qui mettent en cause une possible corruption mémoire:
Error: CRITICAL_STRUCTURE_CORRUPTION
file path: C:\Windows\system32\hal.dll
product: Microsoft® Windows® Operating System

description: Hardware Abstraction Layer DLL
Bug check description: This indicates that the kernel has detected critical kernel code or data corruption.
This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.

Bug check description: This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.

Bug check description: This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: athwbx.sys (Qualcomm Atheros Extensible Wireless LAN device driver, Qualcomm Atheros Communications, Inc.).
Error: IRQL_NOT_LESS_OR_EQUAL

This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.

=> Memtest86+ indique que la mémoire fonctionne correctement, mais les erreurs de windows m'indiquent le contraire! Que faire ? Je n'ai aucun menu sous le bios qui permet de baisser le timing de la mémoire pour vérifier si ça pourrais effectivement venir des barettes. J'aurais bien envie de les garder! D'où pourrais venir le problème autrement ?
PS: J'ai la dernière version du bios, du bios de la CG et du firmware EC.
