IS7: DRAM frequency

[AArDvarK]

"Host DRAM frequency" is set at 200MHZ, as said in my
boot or POST screen, does some have a definition for this? What does it mean? Can it be changed?

It means your ram is running at 200 mhz. Yes, you can change it in the bios. But why?

that is the speed that your DDR RAM is running at and since the ram is doubled, the ram itself is running at 400 Mhz. yes, it can be changed. depending on your ram, you can go in and set things up as user defined and set the NB manually and then set the FSBDR ratio but it would appear that you are currently running at 1:1 and that is a good thing...

oh... just to make it faster. I do Photoshop in which some commands are very heavy and take a long time, same doing 3D rendering though I know that speed is dependant on the CPU mostly.

Thank you for your reply Tom

So what would be proper?

2:1 or 1:2? How does it work to
make the proper change? The RAM
is DDR 400, dual channel Kingston.
Is it running at FSB 800?

it is the internal bus on a CPU that runs at 800 mhz if it is the correct cpu for that feature. 400 mhz, 533 mhz and 800 mhz are some of the possible cpu internal bus speeds. meanwhile, the external FSB runs at 100, 133 or 200 in those situations.

in your case, picking a ratio that *increases* the ram speed might be tough if you start to overclock the FSB. at 1:1 FSBRAM as the FSB increases, the ram speed increases in proportion. if you pick a ratio that is a multiplier as opposed to being a divider, then you will run the possible risk of taking the ram to its limits long before you reach the limits of the cpu overclock ability. overclocking the system is a compromise of getting the best out of the ram and cpu.
