    More or faster memory? (XP Pro SR1)

    Right now I'm operating with the bare minimum 128Mb PC133 RAM, but memory is going on sale at a couple of locations and I'm looking at one of two possible options. My motherboard can support two modules each of PC133 or PC2100 memory:<UL><LI>Buy 256Mb PC133 to add to my existing memory ($19.99 after rebate); or<LI>Buy 256Mb PC2100 to replace (or perhaps add to) the existing memory ($24.99 after rebate).[/list]I'm not sure how mixing memory might affect the system; the board's manual states "You can choose 168-pin SDR SDRAM or 184-pin DDR SDRAM to boot, but the system doesn't start if you use both of them at the same time!" -- which implies that both types can be used but may present some BIOS issues. Given the choice between these options, which would likely give the better performance boost?

    Re: More or faster memory? (XP Pro SR1)

    The way I read that is to take seriously the usual dictum about not mixing any physical variables in memory sticks. You don't say how many pins your existing memory uses. But you may be better off -- at the very low prices -- to dump existing memory and replace with the faster SDRAMs. Seems clear you can't mix the number of pins but you can almost certainly use different memory capacity. Some boards want the smaller capacity chips loaded in the first slots, by the way.

    Re: More or faster memory? (XP Pro SR1)

    Your motherboard, (like mine) supports the use of either 168pin pc133 sdram or 184pin ddr sdram. Not both. Not a bios issue, just doesn't work. (technical gobbledegook goes: the northbridge is engineered to recognize which one of the two it is dealing with, and sets itself up accordingly either/or) Here's a suggestion: dump the pc133 and purchase as much of at least pc2700 ram as you can afford (try eBay - cheap!!!) You will run nice cool ram at pc2100, be ready to overclock if you get bored and want to try and blow things up real good, and will also not be left too far behind if you decide to upgrade your motherboard (my usb 2.0 scanner is so faaassst!!!) XP really gets up and moves above 256, and in my opinion 384 is much better than 256, and 128 ain't happenin. You can get 512mb pc2700 on eBay for less than $50 if you hang in there.

    have fun,

    Well, you said what I was trying to say. MY problem is adding to RDRAM memory for my Dell (XPP, 256 RDRAM) which is $77 or so each for required pair of 128mb anywhere you go.

    But you say eBay? Would I buy memory from a garage sale or am I missing something very important -- as usual? <img src=/S/boxedin.gif border=0 alt=boxedin width=25 height=20>

    Re: More or faster memory? (XP Pro SR1)

    D rasley: Your best bet is to go with the DDR Ram. It's faster and WINXP loves memory like a kid loves candy. Your Motherboard will except both, but not at the same time. If you choose to use DDR make sure you check and see if there is a jumper setting you have to change. Some Motherboards have a jumper setting that must be changed in order to use a different type of memory. But thats no big deal, it's very easy to do. Also you will most likly will have to make changes to your BIOS when changing to DDR Ram, but don't let that scare you. If you will tell us the exact type of Motherboard you have we can tell you how to set it up. You will be exstremly happy when it's set up and ready to go. You will like the Performance.

    Re: More or faster memory? (XP Pro SR1)

    The motherboard is a Shuttle AK32A board; 2 slots for 168-pin and 2 slots for 184-pin memory. To quote from the manual,
    <hr>You do not need to set any jumper to configure memory since the BIOS utility can detect the system memory automatically. You can check the total system memory value in the BIOS Standard CMOS Setup menu... You can easily upgrade the system memory by inserting additional SDRAM modules in available DIMM slots. The total system memory is calculated by simply adding up the memory in all DIMM slots.<hr>
    So it does look like mixing types is out. I could go for the 384Mb total by adding to the PC133 memory, but then it would all have to be replaced to switch to the faster memory. Therefore I think that removing the existing memory in favour of the 256Mb PC2100 would help more in the long run, even though it would be a smaller memory boost right now.

    Re: More or faster memory? (XP Pro SR1)

    what's the limit on size? It's not much more to pick up a 512mb stick than a 256. Also if you do have an upgrade in your future, pc2700 will work (or 3200 but I havent tried that so check) and will be ready for your new system. Then again if you really don't see yourself upgrading soon, you could probably pack it full of pc 133 for pretty cheap. (but remember that ddr=double data rate, meaning pc2100 (266mhz) runs theoretically 4x as fast as pc133)

    just doing my part to add to the confusion....

    I seen 512 MB DDR RAm for 75.00. By the way thats a good Motherboard with VIA KT266A Chipset. That thing should rock with 512 MB of DDR RAM. And maybe a tad bit of overclocking wouldn't hurt either. <img src=/S/yep.gif border=0 alt=yep width=15 height=15>
    From the Manual- Integrated advanced high performance DDR DRAM controller
    Memory
    - 2 x 184-pin DIMM DDR
    - 2 x 168-pin DIMM SDRAM
    2 GB DRAMs (512Mb x8/x16 DRAM technology) for register DDR SDRAM module
    1 GB DRAMs (512Mb x8/x16 DRAM technology) for unbuffered SDR SDRAM module
    Processor
    - AMD Duron CPU with 200 / 266MHz FSB (Upto 2600+)
