why is it that amd socket type mother boards only ever have 4 dimm slots at the most? Intel based boards i have seen have anywhere from 4 to 8 dimms. I have not understood this and has been driving me nuts as I use amd proc, and have 2 extra sticks of 1x2g of ram and noticed that you can't get an amd based motherboard with more than 4. If someone knows why this is i would greatly appreciate to be informed. i have searched forums and no one has an answer for me. thanks

Intel Core i7 and their x58 chipset support triple-channel memory, so you will frequently see up to 6 DDR3 slots in an Intel-based mobo based on the x58 chipset.

AMD has not developed that technology yet.

ok so it has to do with the chipset technology then... i kinda figured as much but for the life of me it was frustrating cuz my board supports up to 16 gigs, yet it only has 4 dimms and i dont want to drop 2 grand on special 4 gig sticks to achieve this... i noticed on new egg that that stuff is far and few between and i was like wow 6 dim slots would really be nice cuz 1x2 gig sticks are so cheap. but i guess thats somthing that i will have to look into doing then is switching to an intel board. that kinda pisses me off that amd is that stupid and won't fix that issue with there chipset... i do a lot of graphic work, and having 12 gigs would be wonderful.

oh and just for your information the intels board with 8 slots can only use 4 at a time as 4 of those slots will de DDR2 the other 4 DDR3 so far 6 useable slots is the most for desktop pc

Its not a chipset issue anymore, its because AMD processors support dual channel, and Intel specifically made the i7 support triple channel. The chipset no longer affects the memory layout as the memory controllers are being built into the chip, you will notice that all boards prior to the i7 only support the use of 4 dimms at a time so its not an AMD issue, its just that intel broke the custom of 4 and went for 6.

Technically, 6 Dimms made sense for tri-channel RAM; whats the point of 4 slots for Tri-channel?

So people can run dual channel mode, should they choose to do so.

They can do that anyway, just use 2 out of 3 Dimms per channel. Hence, why almost all i7 mobo's have either 3 or 6 slots.

I know this forum 6 months old but i figured intel had the adv over amd so that why amd had 4 dim slots and there procs dint support triple channel..

But the phenom been out for awhile (am3 socket) that support triple channel.. Even tho its not really triple channel bc there memory sticks cant work 3 at time..


I am curious why amd doesn't have a board with 6 dimm slots these days so amd can really use the 3triple channel feature..



Who knows amd is underdog ATM they prob got some type memory like OCTTOR channel lol =)
