Mixing single & double sided DIMMs?
I'm looking to buy a socket 939 board and I want to use my existing RAM if
at all possible - I have four Crucial 512Mb DDR400 DIMMs, two of which are single sided and the other two are double sided. If I put the single sided DIMMs on one channel and the double sided DIMMs on the other channel, is this likely to work? Thanks, JB |

Thanks, JB As long as you pair the single with the single and the double with the double it will work fine. |

news As long as you pair the single with the single and the double with the double it will work fine. Thanks for the reply, I was hoping that would be the answer! Next question, will I be able to run the memory at DDR400 in this configuration, or will it fall back to DDR333? Thanks, JB |

Thanks, JB A single sided plus a double sided on each bus will run at DDR400. The speced speed for a system with four double sided DIMMs is 166MHz (DDR333), for a system with two double sided and two single sided the speced speed is 200MHz (DDR400). However if you use faster memory and up the DIMM voltage slightly a system with four double sided DIMMs can run at DDR400 reliably. I have 4G in my X2 4400+ system. Initially I had two pairs of OCZ value RAM. With that configuration I was only able to run at 166MHz. I replaced one pair with OCZ performance RAM and upped the DIMM voltage slightly and I've been running at 200MHz for months without a single hiccup. |
