Memory management error

[ncncore]

I keep getting this message on a BSOD while playing games.

System config :-

CPU- i5 3570k
Mobo- gigabyte Z77X-UP5
Ram- corsair vengeance 4x4Gb 1866Mhz (Bios correctly set)
Os- windows 8.1

This error only started today and the system has been running fine now for 14 months with no sign of this previously.

I am just running memtest86 now but so far no errors have been reported. I still have all 4 sticks in place at present.

What's my next step if this passes with no errors or if I do get errors how do I pinpoint the exact fault.

how much cpu/vtt are you using?

maybe trying 1.08 to 1.10v will help with 16gb

 

[ncncore]

Not sure will check once I have got through this memtest. Currently sat at 56%, still no errors.

Just seems strange that it has been fine for so long and then today it's binning me out.

 

[ncncore]

Ok so it passed fine and my profile vtt voltage is sat at 1.05v but I can't change it.

 

[ncncore]

Scrap that last I have upped it to 1.10v

 

[ncncore]

So it didn't quite BSOD this time with the new voltage setting but it did kick me from the game and mouse movements kept sticking and nothing would really open once I got booted from the game.

Just done a restart and everything seems fine again.

Really quite annoying to say the least.

 

[wazza300]

your running stock clocks or overclocked?

can try a touch more cpu/vtt maybe 1.12v now

 

[ncncore]

I' running my CPU at 4.2 so nothing crazy.

I kept Alt Tabbing and checking Task manager memory tab and it all looked fine then it seems all of a sudden it all goes wrong.

 

[wazza300]

you can look in windows event viewer to see what caused it

click on the warnings and errors,could be not enough cpu v if games spit you to the desktop

 

[ncncore]

Cpu Vcore is at 1.255v

I have just stuck the Vtt to 1.12v now so I will see if that changes anything.

Thanks for the help so far

 

[wazza300]

max safe for cpu/vtt is 1.2v,so can keep testing with more ect

cpu/vtt is for the integrated memory controller inside the cpu,usually needs more with 16gb

 

[ncncore]

Ok so it binned me again but this time the desktop is fine just the game has binned out.

Also there are a lot of critical errors- source - Kernal-power event id - 41 task category- (63)

I think there may be another issue other than memory?

 

[wazza300]

any whea errors/warnings? and if there is click on one and see if it says cpu parity 19

[wazza300]

I think event 19 is cpu voltage related,could try a touch more till you get 0 event 19 warnings/errors

 

[ncncore]

Ok, I wonder if somewhere along the lines the voltage setting dropped down. I will stick it up a touch and see.

 

[wazza300]

it can pass stability tests yet crash with gaming needing more cpu v

are you using a fixed cpu voltage or through dvid?

 

[ncncore]

Fixed I think, just set 1.255v on the vcore bios setting.

 

[wazza300]

for 4.2ghz you could try

pci/cpu clock set to 100
cpu multiplier set to 42x
vcore voltage response set to fast
pwm phase control set to extreme performance

set cpu voltage to normal then set dvid to +0.015v and set loadline calibration to high

enable all power saving then cpu will downclock at idle and use 4.2ghz at load,stress cpu and see what load cpu v is

and adjust dvid so maybe +0.020v or +0.010v and so on till it reads around 1.255v when stressing

 

[ncncore]

Ok there's a new level of info to take in haha!

I will try my best to set that up and see how i get on
