    Who makes the RAM for the CF-30 MK1, I see a company named AXIOM as the MFR. Still trying to decide which RAM mfr to use. Anybody have any info on AXIOM?

    I have never used any ram made by Axiom but any of the name brands of memory will work well in your Toughbook.
    Corsair, Crucial, Patriot and PNY are all good.
    Myself, I always choose Kingston first and have never had any problems...

    It will work as long as it has the same specs to what toughbook you intent to install. I used that same brand for toughbook cf-29 before. You can also verify on toughbook depot. They uses the same brand for toughbook.

    You need either DDR2 PC2-4200 533MHz 200 pin up to 2GB modules or
    DDR2 PC2-5300 667MHz for your MK-1
    I use premium Kingston, but you can use any brand

    There are only a small number of manufacturers that are approved and authorized to make memory modules for Panasonic Toughbook laptops. Certainly most of the Toughbook die-hards here can give you a better sense of what does and does not work in the unit, but officially the memory for the CF-30 is manufactured by Trustin.

    Kingston all the way... Thats what we use in ALL our computers... NO PROBLEMS!

    Also, God forbid it does break, their RMA department is TOP NOTCH, no morons in India.... Takes about 2 minutes to do an RMA :)

    The spec for my MK1 is PC2 4200 CL4

    I see that Kingston has the ValueRam and HyperX. Is the ValueRam Ok? And the HyperX is a CL3, would this still work on my MK1? Dual channel and single channel, whats this as well. Does it refer to how many slots I have?

    Most laptops (Tougbooks included) are single channel... they have 2 slots with 4GB max... You can use DDR2 5300 or higher... it will downclock automatically to the correct 4200 (533mhz) speed. (IE, if you can get the higher speed DDR2 RAM for less money then just do that)... Valueram is what you are after. Check newegg.com - they are the cheapest around

    Actually... DDR2 IS dual channel - it's just on one slot rather than two. That's why you cannot use it in place of similar speed DDR.

    When you get into dual-core processors its a whole new game. Theoretically you double the bus width, so need 2 DDR2 slots (Or one DDR4 slot) for dual-channel. In practice, manufacturers often just recycle a single-core design and reprogram/redesign the memory controller for compatibility with the dual-core processor; this is what CAN BE so confusing about the dual (or even quad-core) designs.

    Don't feel too bad about it though, every time there's a new jump in processor technology (8-bit to 16 bit, 16-bit to 32-bit, 32-bit to 64-bit etc) manufacturers have done EXACTLY THIS to capitalize on EXISTING tooling expense before upgrading to the next level.

    mnem, not trying to pick a fight here but just because it's ddr2 does NOT mean it's dual channel... The architecture allows for greater speeds because the memory chips themselves are faster.

    As per the wiki: "DDR2 allows higher bus speed and requires lower power by running the internal clock at one quarter the speed of the data bus. The two factors combine to require a total of 4 data transfers per internal clock cycle."

    Also remember that when your clock speed goes up your latency ALSO goes up.

    JB -

    The DDR2 specification refers to the PHYSICAL architecture. DDR2 is PHYSICALLY different; it won't even fit into a DDR slot. It IS Double-Data-Rate RAM (meaning it accesses the RAM on both the up-tick and the down-tick of the processor clock), but it is ALSO DUAL-CHANNEL.

    DDR and DDR2 both perform multiple data transfers during a single clock cycle, but dual-channel specifically is a mode of operation available only when pairs of chips are used.

    Let's try to get back on topic here, okay?
