Hi guys. After a little help and advise please.
System spec:
ASUS M5A97 EVO
Kingston Hyper X Genesis 1600mhz 1.65v
Powercolor R9 270 Turbo Duo
Phenom X6 1055t
Hyper 212 evo
XFX pro 550W
Transcend 120GB SSD for OS
NZXT S340 with 4x120mm (so reasonably good airflow)
Issue: The long and short of it is, if I use my RAM in normal configuration, 2x4GB sticks in A2 and B2 (as set out in manual as default) I get BSOD, usually within minutes of starting up, even during boot up. And even during windows installation.
I have run memtest for 8 hours on each indivual stick, and both were OK.
If I use either stick in slot A2, system is fine.
If I use both sticks in A1 and A2, system is fine.
If I use sticks in default A2 and B2, BSOD.
If I use either stick in B2, BSOD.
If I use either stick in A1, system is fine.
If I use either stick in B1, system wont even boot, black screen no video feed to monitor.
So its the two slots furthest from CPU.
Back story
System has been running ok for a best part of two years I think, CPU was OC to 3.4ghz via FSB @ 1.375V (high for this speed, but needed for stability) temps in 50's for gaming. I did have northbridge OC to 2.4ghz @1.25v. Video card also was used OC via MSI afterburner.
Recently started getting GSOD (vertical lines, repeating sound and freeze), so I dropped memory OC on video card back.
GSOD stopped.
Playing Dungeon Defenders two, and constant CTD and lockups.
Reinstalled video drivers.
About this time, im not 100% sure of order, I began to get BSOD.
Uninstalled video drivers, could no longer log in as video was 'messed up'. Login screen was zoomed in, pixelated. Had typical video card related crashes. Ill post images later, need to sleep soon! Techy guy I know thinks this points to video card fault, however I am thinking GSOD due to memory overclock becoming unstable, and further issues due to me doing something stupid with drivers somehow. As this issue has not re-occured.
Ran SFC \ scannow, found errors but unable to fix. Decided windows refresh was a good idea (?), BSOD DURING refresh.
Went for reformat and install.
This is where I am at now, have basic drivers installed, and OCCT installed for testing.
I am suspecting either motherboard or CPU in that order?
Is it possible ive done damage to Northbridge by clocking it?
Any firther tests you would reccomend? Perhaps bios flash? (Im 95.8% sure I did this soon after getting mobo, but whether there is a newer bios update available I havnt checked yet)
Thanks in advance
P.S. Have tried leaving RAM to auto in BIOS (which sets timings loose at 11-11-11-30something) and have tried manually setting to 9-9-9-27 which is spec for my RAM. No difference.
