TWIN2X2048-6400C4 + Asus P5N-E SLI

[jimmysmith]

I've been having difficulties with having my system run stable with my Corsair Twin2X2048-6400C4 memory. I've manually adjusted the bios memory timings to factory specs and I can currently boot into Windows and run stable from 30min up to an hour or two however I regularly get BSOD's. The error message is always the same, "bad_pool_header, Stop: 0x0000000019". Please advise if I should make any other adjustments or if additional information is needed.


Bios Settings:
SLI-Ready Memory=Disabled (Unable to load O/S with any other setting)
Memory Voltage=2.085V
tCL=4
tRCD=4
tRP=4
tRAS=12
CMD=2
All other memory settings @ auto

[Legend]

tCL=4
tRCD=4
tRP=4
tRAS=12
CMD=2
TRC= 24
TRFC= 42
DDR Voltage: 1.95

Anyone not getting Blue Screens in Vista?

Since my initial post above, I've tried moving my memory sticks into the black slots and the system became even less stable than before.

I've since returned the memory sticks back into the yellow slots and have adjusted some of the advanced memory timings. With my current settings, my system has been stable now for approximately 4 days with no more BSODs. I hope this information will help some others with similar components. I will update this thread should I experience any changes.

Current settings are noted below...

Bios Settings:
SLI-Ready Memory = Disabled
Memory Voltage = 2.085
tCL = 4
tRCD = 4
tRP = 4
tRAS = 12
CMD = 2
Advanced Memory Timings
tRC = 22
tWTR = 15
All other settings = auto

I have almost the same config as Jimmy and I experienced the same problems with windows crashing (freezing up) also had memtest86+ report mad errors . The timings Jimmy listed in the follow-up post completely corrected my problems. Thanks Jimmy!

I have the same MB and RAM Described and went into panic when the wonderful BSOD appeared. This I was not expecting...

I used the "JimmySmith" settings, and all is well so far.

Thank you "JimmySmith", and if anyone finds any tweaks to this configuration, please post.

I would try the modules in the other two slots, also what was the stop errors code? You can search for it at www.microsoft.com/technet.

Hi,

Just registered to say thanks to jimmysmith. That post really helped me achieve stability with my system and I appreciate the time you took to share the solution.

Ok, I have the same problem everybody here, but using the advice of the jimmysmith friend I have solved the issue... for now...

I'll explain myself: I double boot XP Pro and Vista Ultimate, the Vista bootloader has a "Memory Test" included and there is no way I pass it using any memory configuration (always gives an error, BUT memtest 1.36+ pass the test runnig a whole night. What doews this mean? I don't know... I'll post if in few days there comes instability in my box.

BTW I'm using the latest Asus Bios, Version 602

Thanks Jimmy Smith!

Ripping my hair out for 2 days.. this fixed my issue in 5mins.

Woot!

Thanks Jimmy Smith,

Same mobo, almost same RAM (3Gig), same problem, now seems to be fixed, memtest+ 1.70 not displaying any errors at the moment, memory speed down at bit, (3351MB/s), shame.

Claggy.

Yup, this worked for me as well. Many Thanks to all who contributed.

[jimmysmith]

Wow, I'm glad to know that all of the time that I spent trying to find the best timings for me, could also help so many others.

Just a little update, I've recently upgraded to the Bios 0608 and have had no problems with the same memory timings.

[RAM GUY]

Thanks for the update and good luck.
