Cas only affects the very first access cycle so you wont notice any difference

Page file is fine and shouldnt intefere in any way

System restore is OK. Does hog resources but shouldnt affect anything.

Lol - still ere!

I noticed that when I just had one stick in, the mobo reported that it was running at 400DDR - thats the Dual Channel setting isnt it?  Will that damage the RAM and is it possible to run the memory at 400DDR in non-dual channel?... i.e. in slots 1 and 2 (3 being the slot which produced a CTD).

 
So I can still rate them at 400DDR?  Just not dual channel?

Will I lose much performance?

wait a min.... you had the problems before the upgrade ?  I thought they were new after the upgrade

that points away from the windows fault (a bit anyway)

from your mempry tests Id say it is a memory issue.

stick A is ok in slot 1 and 2, CTD in slot 3
stick B is ok in slot 3

A in 2, B in 3, BSOD

you need to test it a bit more, try leaving sick B in slot 3 for a few days, make sure its deffo. ok

try the sticks in slots 1 and 2

dual channel makes naff all real difference tbh.


either youve got an iffy stick of ram, or slot 3 is iffy.

what if you go back to your old ram ?
if it still does it then, then its the slot.

TBC...

Thats what I wanted to hear. What I think Ill do is whack the sticks in 1 and 2, avoiding 3.  See what happens. (I previously had them in 2 and 3)

I take it then, that Ican still run them at 400DDR?...

Cheers.

 
Fresh reinstall!



Still CTDing...  
 

Have you tired what I suggested of just having a stick of Ram in slot 1 yet?

Yup

try the sticks in slots 1 and 2

That too.

Hmm. Nightmare.

What about the PCI/Busmastering issue - we didnt quite agree on the way forward on that one.  On of off?

Others have suggested its a heat issue but I dont think so - Tomb Raider: Legend CTDd (consistently) within the first couple of minutes.  SWBFII (cranked way high) lasted anything up to two hours.  Oh, and it occasionally crashes when in Windows too. So, no; it cant be heat.

Thinking about using just the one stick again - if it works, its a workaround - but Id be pretty miffed as Ive just forked out £100+ on a new pair.

Bleedin pooters...
