at first the ram speed was set to 200mhz (bios allows for setting 200-533 mhz range)in the bios, the fsb ram was 1:2 (using cpuz), then i increased the ram speed to 333mhz in bios, and the fsb:ram changed to 3:5.
what should be my ram speed? what speed should i set it in the bios? i bought 4 gigs of corsair 1066 mhz ddr2 ram
For a standard DDR2 system the clocks are doubled.
Setting 533 for ram clock times (2) happens internally, equals 1066 which is the maximum setting for many DDR2 boards.
DDR2 x 200 = 400 mhz
DDR2 x 333.3 = 667 mhz
DDR2 x 400 = 800 mhz
DDR2 x 533 = 1066 mhz for PC2 8500 chipps
zipzoomflyhigh is right. it should be 1066, especially if your motherboard supports it. that should give you the most amount of bandwidth for your RAM. If ur just running it at anything lower than 533, then it will just be a bottleneck which will in turn slow down the overall performance of the system.
