    Default Geil RAM - Timing problem

    I picked up a pair of 512 MB Geil RAM that are supposed to run at 1.5-2-2-5 at DDR400, but I can't seem to get it to that point without errors. Even with the Command rate at 2T.

    I've read a lot about RAM but I still can't seem to make sense of it. Any suggestions.

    My specs for this rig are listed here with the exception of the RAM (haven't updated that info yet.)

    What motherboard do you have? What voltages have you applied?

    DFI Lanparty Ultra-D.

    I haven't taken the voltage any higher than 2.85v

    I'm not familiar with what voltage is necessary to get that particular RAM to CAS 1.5, but try more voltage anyway. Also, what kind of cooling does the RAM have?

    Is this RAM you bought secondhand from someone that had it running at that rate? Just curious, because if thats the case you may not be able to pull it off.

    Either way, give it some more voltage for sure.

    No these sticks are new. I've got two 60mm fans, but I haven't attached them yet. Not quite sure how to. I superglued them to the heatspreaders last time but I think that damaged the RAM.

    Technically I think this RAM is supposed to 2.6-2.8v.

    Does anyone know a safe way to attach these fans?

    You don't attach the fans; you point them at the RAM. Just find an effective way to aim the fans at the RAM and keep the fans towards the front or the side. RAM default voltages are generally between 2.6v and 2.8v. For higher speeds or lower latencies, you generally need to go over 3v. I'd imagine CAS 1.5 requires somewhere around 3.2v.

    RAM can take a ton of voltage as long as properly cooled.
