1200 MHz memory motherboard

[TheOmegaSoldier]

I recently read that Kingston is releasing memory that clocks at 1200 MHz. Will that work on a normal motherboard or do I need a super high end one that explicitly supports it?

Are you sure it isn't maybe clocking at 600MHz (DDR2-1200)?
In any case, no known MB will reach 1200MHz memory bus clock, and many will not reach 600MHz. I doubt you'll find a MB that explicitly supports it, but some MBs are likely to be able to successfully OC the memory bus that high.

Perhaps the real question is why? C2Ds normally run 266MHz FSB clocks, so OCing a C2D FSB to 600MHz is asking a lot.

Sssup Omega,

You will need a mobo that supports overclocking the front side bus. All the major companies have them. I like Asus the best but you could also look at Gigabyte, MSI, DFI and others. Most boards made by these companies support overclocking. Check your manual and look under BIOS settings, you can also check the forums for advice on which mobos are best for overclocking. I've already used the Kingston HyperX 8500's to get to 1066 on my Asus 975 board and I think I can go faster with their 1200's.

Hello Mondo,

Some 975 mobos like Asus will support 1333Mhz FSB setting for the C2D so getting memory to 1200 would be pretty simple to do, need a good PSU though.

My FSB is running at 1644Mhz, which is running the memory at DDR822 in a 1:1 ratio. I know that DDR1200 is in the BIOS menu, so I'm sure it would run asyncronously at a ratio of 2:3.

 

[TheOmegaSoldier]

Ok so it's a bios setting?

 

[CompuTronix]

Yes, that's correct.

To DDR2-1200, yes. To DDR2-2400 (1200MHz clock), no. However, I'm guessing the OP meant DDR2-1200, not 1200MHz clock rate.

Yah must be memory speed he's asking about, but imagine when memory does get over 2Ghz. DDR3 will get close. 1333 and 1666 will be do-able later next year. I wonder what the latencies will be though....

It is 600Mhz. Memory have multipliers, 1:1 being the most used.

Memory is DUAL DATA RATE. meaning if you have DDR-1200

1200/2=600Mhz.

there are a few multipliers i don't remember all at the top of my head but
3:2 For every 3 Mhz of FSB memory runs at 2Mhz
1:1 For every 1 Mhz of FSB memory runs at 1Mhz
4:5 For every 4 Mhz of FSB memory runs at 5Mhz
Or is it the other way around??? :roll: :lol:

And so on
