Hi guys,

I'm having a couple of problems with my setup. I'm running the following: -

Abit Ip35 pro
Q6600 @ 3.2 gig (1.3 volts)
4 gig Crucial ballistix tracers (2.2 volts)
Evga Geforce 8800 GTS 512meg (stock speeds atm)

Basically im getting BSOD when booting Vista. Now i had this problem occur about 2 weeks after getting the pc and running the current Overclock (Q6600 @3.2, Memory at 1068 mhz). So i upped the MCH voltage from stock 1.25 to 1.32 volts. The issue whnt away completley for two months.

Tonight it re-occurred cant boot into windows at all BSODS on any attempts.

So i upped the mch again to 1.37 and again it now seems stable.

Is this mch voltage ok? Temperature wise my case is running around 30C, cpu is about 35-40c and the Pwm is showing about 45c.

Is my memory dying or is this just an issue with needing that little bit extra out voltage on the northbridge?
 
BSOD's and Ballistix rings alarm bells.

1.37v is fine, but I would still run a couple of passes of Memtest86+ to check the memory.
 
Well i ran memtest initially and it cameback tellnig me there were errors.

So i started testing the sticks individiually and in pairs (maintained the overclock but dropped the mch voltage to 1.25). Each stick passed individually and in pairs. I put the 4 gig back in together (still at 1.25 volts ansd overclocked) and they also passed the tests.

I can currently boot into vista and run my overclock fine with the mch at only 1.25 volts.

I get the feeling that the memory may be over heating the 4 gig are very close to each other and there isn't really any real air flow over them (other than the cpu fan pulling air away o blow out the back).

I'm tryin to run the pc now with the case open to let more air in to see how that works. Anyone got any thoughts on what else i can try?
 
Hi dai, Sounds very similar to what I had before I had to RMA my rig back to Overclockers last week with a similar setup as yours. Everything was fine for about two weeks then BSOD, then sometimes it would hang while rebooting with post code 87 and displaying no operating system.
After leaving it off for about ten minutes it would start without any problems.
Sill waiting for a reply from Overclockers.

I had the 5300 set and both sets failed weeks after each other but I'm certain half the time Crucial don't even test they just ship new RAM as my returned sticks were tracked and they got there after my new set was dispatched?

But I also didn't get errors on memtest but I swapped and tested everything with friends hardware so it had to be the ram I thought.....
 
hmm interesting,

Well my rig is working fine atm (fingers crossed). I guess i'll just have to keep an eye on it; Dont realy want to rma all 4 gig as it may only be 1 stick causing issues but atm i cant identify which one it may be.

RMAing all 4 may be the only thing i can do though if i keep getting problems i guess.
 
i suggest you use a different memory tester program, something like goldmemory or windows vistas own memory tester since they provideo more streneous tests and can usually find errors faster than memtest can.

vistas memtester uses a good test called stride6 or something which is very good at clamping down errors.
 
hey up,

bit late to the party, I had the same problem, and knew it wasnt temp related or anything else. Turned out it was my craptastic ballastix, Crucial ballistix tracers. 4gb worth of crap. As soon as i took the balls-istix out and put my g-skill 6400hz's back in all is peachy again.

Same board same chip and same mem as you apart from my cpu is underwater. :(

shame, the ballistix tracers were running fine for about 2 months at 1044mhz at 2.2v so not as if they were even pushed lol
