    +1 ^^

    Mixing ram is not advised at all, especially when trying to do so with 8GB

    Save yourself the hassle and remove a set and stick with 4GB, or if you actually need and use 8GB then your best bet is to buy a matched set of either so all sticks are the same

    It sounds like discretion is the better part of valor on this one. I'll return the Ram and go a different route. Thanks for all the advice.

    Excellent decision. You won't notice the difference between 4GB and 8GB really unless you Ray Trace, hardcore audio/video edit or run a lot of Virtual Machines.

    Save the cash from your RAM and put it towards getting a small SSD, like the X32 in my sig. You will then receive a big discernable performance increase and can use your old HDD's for storage and programs. An OS and commonly used programs on a SSD is a revolution indeed.

    I see you have a similer setup as mine. I have 2 x 1Gb of ram, Its corsair dominator, I bought another 2 x 1GB of Corsair dominator its the same DDR2 1066 but the other 2 are xms2 and when I use all the computer wont boot, It wont post to bios it just keeps restarting. I dont understand it is pretty much the same ram correct? The bios is updated, I clears the cmos switched slots, nothing, it only boots with 2 GB of either. Any thoughts?

    All Corsair RAM will have a version number written on the module label. Even RAM of the exact same model and spec for example your Dominator, can actually be completely different RAM, different RAM chips (IC's), different PCB, the lot. This is why it's crucial to buy RAM in matched sets. Unfortunately it may be that you'd have been better off buying 2x2G of Dominator and eBaying your old set.

    You can try booting with 2 sticks and going into the BIOS. When in there, change RAM timings manually to match the RAM specs, voltage too and also add a little to the MCH voltage seeing as you're now populating all RAM slots. With 4 sticks, regardless of capacity, it would be wise to start at 1.2V MCH Core and work your way up to see if it helps.

    Edit, I re-read your post. You say 2 sticks are Dominator and two are standard XMS2? In this case they will be completely different sticks. Dominator will be sourced from a different manufacturer as it's a premium line. Remember, Corsair don't manufacture RAM, they simply buy bits off the shelf and stick them together.
