There is a problem with i865 chipset and DDR400 modules when you set
Ras to Cas Delay, as Corsair has said:
The problem is the chipset won't handle a tRCD (RAS to CAS Delay) of
2. We've done a revision of the SPD to make the LL's work on the 875
and 865 chipsets, the settings are now 2-3-2-6 by default.
We will, of course, warranty any modules with the older SPD but it
should be noted that the end user can simply manually adjust the BIOS
to the settings noted above.
I hope this helps you :D
I have the exact same setup as the first guy above. And I was also
able to avoid setup lockups and blue screens by adjusting the mhz of
the ram down to 320. How would I go about changing the Ras to Cas
Delay?
Your BIOS reads SPD RAM timings from your Corsair Modules and sets
automaticaly your CAS, Ras to Cas, etc... But you can change your
timings in your BIOS and force Ras to Cas to 3 to avoid problems with
i865 boards.
2-3-2-6 stands for CAS Latency, RAS to CAS Delay, RAS Precharge, and
Precharge Delay (in that order) so:
CAS Latency = 2
RAS to CAS Delay = 3
RAS Precharge = 2
Precharge Delay = 6
