They're guaranteed @ 2-2-2-5-1T for one pair, but not 2 pairs. try 2.5-3-3-6-2T and tighten from there. It may be possible to get them @ 2-2-2-5-2T.

 

FYI, the order of the first 4 numbers is:

 

CAS Latency (tCL):

RAS to CAS Delay (tRCD):

Row Precharge (tRP):

Active to Precharge Delay (tRAS):

 

Also:

Memory Voltage: 2.75 Volts

All other settings to defaults.

thanks for the quick reply but 2T is for AMD MOBO ?? I have a P4P800 E DELUXE MB.

 

Intel chipsets do not officially support command rate. Thus, the "command rate" (or "1T/2T") setting on most Intel chipset-based mobos is permanently fixed at one setting (equivalent to 2T).

thanks for the reply. I just put 4 sticks on this MOBO and the setting is 2.2.2.5

ddr voltage: 2.75

 

its blazing fast . should i keep it this way. any1 has any suggestions ?

Also, check your memory clockspeed. You may be downclocked to 166MHz (DDR333/PC2700) with four double-sided modules installed on your mobo. The i865PE chipset, like all DDR400 chipsets, supports only two rows of memory at DDR400 (200MHz/PC3200) per channel. But one double-sided module counts as two rows of memory. Thus, if more than two double-rank modules are used, the memory clockspeed must be downclocked to 166MHz (DDR333/PC2700) in order to remain stable.

I still see it at DDR400 when booting. but should it keep this setting ? would this setting ruin my rams in long run? thanks again

Can you expand on this. Would you say this is true of the 875 chipset as well? If the bios indicates that 4 sticks of DDR are running at 400 MHz does that mean that they are but the system is unstable or does it mean that the bios is wrong. Wouldn't that also show up in memtest or in benchmarking software e.g.Everest, Sandra?
