Recommended Posts

Hello

 

i have made a new computer last month with best items for overclocking but i have a problem with my kit Twinx2048 XMS 4000PT modules they aren't stable at 250Mhz ... !?

 

my config :

 

A8N32-SLI

Opteron 175

2x1Go XMS 4000PT

Maxtor 40Go 2mo cache IDE

IBM Hitachi 80Go 8mo cache IDE

Enermax Liberty 500W

Leadtek 7600GT 256Mo

 

at FSB 200 all is ok and XMS 4000PT 200mhz cas 2.5 / 7-3-3 ok 2.8Vdimm

11x200mhz opteron 2.2Ghz ok

 

at origine timings 10-4-4 cas 3 or 8-3-3 cas 3 FSB 250mhz i can run windows and go to internet, outlook express, run superpi 1M but failure à 32M ! and crasch in all games return to desktop without any message !

mit 11x250mhz opteron 2.75Ghz ok

 

its not a processor probleme because it take 2.8ghz at 11x250Mhz with 166mhz desynchronisation memory so the memory is at 200mhz and run ok superpi 32M no problem in games with 2 Dark Age of Camelot game full graphism on the same system !!! always at 7-3-3 CAS 2.5 2.8Vdimm

 

i would like to synchronise my memory just to 250mhz with the cpu to have 11x250mhz cpu and 250mhz memory at origin timings !

 

i bought this memory 300€ at i want they work

 

i try 2.8Vdimm and 2.9Vdimm the memory is not stable and crash in game always and superpi 32M failure

 

what is the problem ?

 

how to change the memory ? at my shop or at corsair support ?

 

i repeat the memories where bought february 2007

 

here the informations written on the memory modules

07020378-1

CMX1024-4000PT

XMS4000

hi

 

i search on the net

 

XMS-PC4000 Rev3.1 (3-4-4-8 ) -> Samsung TCCC supported by A8N32-SLI bis 250Mhz

XMS-PC4400 Rev1.1 (3-4-4-8-1T) -> Hynix D5 not supported by A8N32-SLI at 250Mhz

 

the Corsair Memory Guide make test on the A8N32-SLI with Rev3.1 so with Samsung TCCC chip

 

can i change my modules Rev1.1 again modules Rev3.1 by Corsair ? or must i change by my shop again other brand with PC4000 ? i had no problems with Corsair by yet :(

 

what must i do ? how to change the memory modules by Corsair ?

 

thanks a lot

Where are you seeing they are not compatible, The modules based on Hynix were made and ended production before the release of this MB is what I think you are seeing. And I am sorry we dont have any kind of a upgrade option, but we can try and RMA your modules again if you like!
