Hi Guys,

I've been through four RMA's with OCUK with my Corsair Dominator ddr2 1066 4GB Ram.

Finally they sent a kit that started working as it should, memtest passed all tests and it was working great.

Until today where I started getting a random BSOD after just browsing the net, the BSOD directed to "MEMORY_MANAGEMENT" & "PAGE_FAULT_IN_NON_PAGED_AREA"

I immediately booted with memtest and ran the test, 6 minutes in I get memtest errors, I'm back to square one!

What shall I do??
 
What's your DRAM voltage set at? Have you set these to run at default or have you manually set the timings?
 
I've manually set the RAM at:

2.1v 5-5-5-15 1066Mhz, all default rated settings and still not going good.

Yes I have my CPU oc'd to 3.7ghz, but I already have tried doing the test at stock speeds

not to try and take traffic away, but have you asked on the Corsair forums? When I couldn't get my OCZ memory working, posted up on there and had it working fully stable within 2 days, that is from a system that wouldn't post, to then one that would crash and bsod

Yes I have gone to the corsair forums. They helped but nothing worked. They actually blamed my mobo n CPU :o

it honestly wouldn't surprise me if they were right...I mean 4 fully tested (that is very rigorous corsair testing) matched pairs to be faulty and for atleast one of the pairs to be totally fine and pass 24 hours of memtest...to then go to crap? Sounds extremely unlikely to me.

If you have some memory that you know works absolutely fine, put that in there and see if that goes to pot too. If it does, you know the guys over at Corsair were right that it is your mobo (which I would suspect first) or CPU

I have some ocz reapers that work 100% on my mobo so I do blame the corsair. I migh just go to GSKILL or OCZ.
 
What mobo are you running these on mate? My Dominators throw up a fuss when run in Dual channel on my P5Q Deluxe, when in single channel they're happy as larry. The performance difference isn't noticeable at all.

Give single channel a go and see if it can stop your headaches.

I'm using an ASUS M3A79-T Deluxe, running the stick in dual channel with the black slots due to my Megahalems being in the way.

Something weird, I just disabled CnQ and C1E in the BIOS and I left my system Idle for over 2 hours and no BSOD, but memtest still throws errors, if I get another BSOD then I'll try it, it's quite a fuss to take my case out (Antec 1200) so I'll try the single channel later.

I might just sell this memory and get something else.
 
When you raise the FSB beyond stock speed then memory is less likely to keep up even if you alter the ratio (to keep your mem under 1066MHz). The North Bridge (NB) is responsible for this on your mobo the faster you clock, the more voltage it needs to keep up - so its not just your RAM but your mobo NB that is in need of attention - increasing the NB voltage can overcome this within reason of course.
Testing takes time and needs to be done in increments, I personally cant run my RAM past 980 GHz when my FSB is high (390x9). I have increased voltages but there is a limit to which the hardware can go and to which I'm prepared to risk damaging my PC.
My RAM works fine at stock speed of ~1066 MHz with 5-5-5-15 timings (200 FSB x 9 Muliplier = 1.8 GHz CPU) but needs tweaking up of the voltage on both the NB and RAM to get it past that. Im happy where it is without excessive overvolting. I use 2.1v on my RAM and the NB is increased 0.225v, there are other voltage settings too (CPU, PLL etc..) but essentially this is what needs to be done for me - your requirements will be personal to you.

The memory controller on the P2's doesn't really like running DDR2 at 1066mhz.
Sometimes you get away with it but it is on the edge.

Most boards recommend only 2 simms at 1066mhz but sometimes the onboard memory controller in the P2 won't play nice even with only 2 simms at 1066mhz.

You end up either swapping brands until you find some ram it does like, or run at 800 instead of 1066.
Also you could set cl2 instead of cl1 but you will get a small performnce hit.

Runniing single channel may work but you will cut your memory bandwith right down.
Not a problem if you only game at GPU limited res but for any intensive processing such as encoding or number crunching you would be very unhappy with the slow down.

My 940 is real fussy at 1066, it likes Kingston HyperX and OCZ but doesn't like Corsair or Geil.

Later P2's are more memory friendly i believe.

Oh right thanks for the info there. Seems like the same problems as me then. I was thinking about investing in the 6 core phenom or one of the new i7's or just a 920 D0.
