DDR 2700 in a 2100-supporting mobo

[srsanborn]

What are the repurcussions of installing 2700 DDR into a motherboard that only officially supports up-to DDR 2100? My thinking is that if the 2100/2700 are simply theoretical bandwidth numbers, it shouldn't matter - the 2700 would just max at 2100 speed, but no negative effects would occur.

Anyone have input? I have the opportunity to buy some 2700 cheap from a friend, (512 DDR 2700 to add to my existing 512 DDR 2100) but want to make sure I won't end up with more headaches than it's worth. TIA.

No problem.

It's not really a matter of bandwidth, but rather clock speed. PC2700 is essentially the same RAM as PC2100, it's just that one is rated for operation at 333MHz DDR and the other is rated at 266MHz DDR.

It will work fine. In fact, getting a higher rated speed RAM is better if u decide to O/C or simply upgrade in the future.

Faster is better with DDR... all the ddr slot are currently the same so you can stick some PC-3700 in a PC-2100 slot....too bad it won't run at PC-3700 speeds though
