MSI K9A2 Neo-F and RAM Voltages, Timings.

Question

Hi, I recently purchased the K9A2 Neo-F mobo and just yesterday picked up a 2x2GB kit of DDR2 (800) OCZ Platinum memory. The RAM can run at 2.1 V to achieve better timings but I'm not sure if pushing the voltage on the motherboard is possible or safe. In BIOS, all of the DRAM settings are greyed out.
The RAM is currently at 371.5 MHz with a 6-6-6-18 timing. Could be at 400 MHz with 5-4-4-15.
Any help/advice is appreciated.

Answer 1

1 The processor speed in MHz is pre-set.
2 The bus to the outside must have the same speed in both ends of the line, of course.
3 2600 in this example can't gear down to and use the bus speed 400 with a "decimal" figure. It simply can't!
4 It uses the closest upward figure, to get as close to the speed as possible.
The multiplier isn't exactly involved here in this example, but for the resemblance of the figure 7. It is a bit complicated, but you want a fast processor and cheap memory. At the same time you want the processor to work smoothly with the memory. So they use a clock multiplier to get a fast processor. When it has done it's job, the data sent out uses a speed geared down to a usable speed, which is the maximum speed of the bus.
To complicate things a little more... No, let's stop here.
