Question about Ratios

[eka42]

Just wondering. Can the 965P-DS3 Gigabyte Mobo Reach the 5:4 Ratio, 5 being the ram, 4 FSB. If not. Is there anyway i can reach 325 FSB on a 6420 (2.6) While maintaining AROUND 800 MHZ ddr2.

I don't know about the 965 but with the Gigabyte 945 socket 775 you would enter the BIOS and hit Ctrl-F1, and then enter the MIT Menu:

CPU Host Clock: Enabled
CPU Host Frequency (baseline): 266
PCI Express Frequency: Auto
(some folks set at 100)

By earlier hitting Ctrl-F1 you enable additional memory settings that you can now loosen a bit.

Now you have to do some math. RAM frequency equals CPU Host Frequency multiplied by the System Memory Multiplier. You have a choice between 2, 3, 4 & 2.66.

I would prefer working my way up slowly from 266 maybe 5-10% a boot but some folks think that is a little Old School.

Depending on your RAM multiplier I'd be aiming for:

8X400 = 3200

Good Luck!

Why don't you use to 2.00 setting and run everything at 400mhz FSB. The ram, the board and the chip can handle it. If you don't want to overclock the chip to much, drop the multiplier down to 7. You will see a huge improvement in performance, and its is also a little bit better to run the memory synchronously with the FSB of the chip.

on the 965P-DS3 with your pc6400 run 8X500 with the ram multiplier @ 2 and the CPU/RAM divider @ 5:4 ???

Just wonderin' . . . and I didn't mean to hijack this thread because the OP is asking the opposite . . .
