Recommended Posts



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 :

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

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!
