Command Rate vs. CAS - Which Is Faster?
Thursday, April 05, 2012 4:37 PM
Is better to run RAM at a lower CAS (7) at 2T or at a higher CAS (9) at 1T?
Here are the particulars from the Corsair site:
Corsair Dominator - CMP16GX3M4X1600C7
Size: 16GB Kit (4 x 4GB)
Performance Profile: XMP
Tested Voltage: 1.5
SPD Voltage: 1.5
Speed Rating: PC3-16000 (2000MHz)
SPD Speed: 1333Mhz
Tested Speed: 1600Mhz
Tested Latency: 7-8-8-24
SPD Latency: 9-9-9-24
Command Rate: ?
The EVGA ELEET app say 9-9-9-24 at 1T. At this setting in auto, it will boot and run Prime 95 with no errors.
If I change it to 7-8-8-24 at 1T it will not boot. 2T boots and I can run Prime 95 with no errors.
Thanks for advance for your help. <04-05-2012 9:28 pm edited for use of the proper name, "command rate" and not clock rate>
