    Hi,

    Just received my M15x with the corei7 820qm processor. The BIOS is A01 with EC v0.96. In the bios under the memory section, it reports 4gb of ram running at 1333mhz. However, it reports the ram running in a single channel configuration? Have I got a problem, or is everyone in the same boat as me?

    A very weird issue as I thought the BIOS should be reporting a dual channel configuration.

    Any help or confirmation would be great. Thanks.

    thats odd, I purchased the M15x with dual channel ram, so the BIOS should report a dual channel configuration. This is quite wierd.

    The driverheaven review of the M15x showed a bios screenshot with a dual channel configuration. The only difference between their memory configuration and mine is that they used an unlinked configuration whereas I used a linked configuration. I dont intend on overclocking my CPU so would rather leave the ram linked to the CPU.

    I think its a bug in the BIOS. The BIOS screen should show dual channel. I'd hate to be losing some performance just because the bios couldnt recognise the ram configuration.

    Ive used memtest86+ and CPUZ and a few other memory analysing programs, all report dual channel. So could be a bug on the BIOS reporting screen.

    Just spoke with XPS support and they told confirmed it was a bug in the BIOS reporting screen. They told me to use CPUZ (I already did) and since that reported a dual channel configuration, everything should be fine.

    He also mentioned that the new BIOS update (presumably A03) would fix this problem up and to not worry too much about it.

    I guess that resolves it, thanks all for your input!

    Hi, I've got the A03 bios, and my BIOS reports:
    Memory Bank 0: 2048MB
    Memory Bank 1: 2048MB

    I'm assuming this is what you mean by reporting dual channel?
