Do any P965 boards support memory dividers?

smilingcrow · Aug 6, 2006

Is it possible that the P965 chipset simply doesn’t allow the memory to run slower than the FSB? E.g. FSB = 400 RAM = 800. Or will a BIOS update allow this in the DS3 or other boards!

I ask because I’ve been disappointed to see that the Gigabyte DS3 doesn’t allow the RAM to run slower than the FSB; I have PC5300 and the extra expense of moving to PC6400 is more than the difference between a P965 and 975X board, so not appealing.

If this is the case, I shall just wait to see what the ATI & Nvidia chipsets support.

i dont get the problem here pc5300/pc5400 is ddr2-667. in order to get you ram to run at ddr2-400 would be to set the fsb to 200 mhz with a 1:1 ratio. pc6400 ram is dd2-800. Lower ram speed with a stock FSB of 1066 is not going to happen the best you can do is a 1:1 ratio which would be dd2-533.

sorry i would have said something but i didnt notice this thread.

You could attempt to OC your ram by loosening the latency timings and increasing voltage. DDR2 667 RAM on a Conroe system would run 1:1 at stock speed with a FSB of 333MHz. Any FSB above that is when you actually start OCing the ram.
