HEY! where did half my RAM go!?!

    I just installed 2 x Compaq 256Mb ECC SDRAM 133Mhz, and my puta thinks it's half the RAM it should be.. it shows up as 261,616Kb of RAM.<br>
    I've got a MSI6153VA v.2.1 motherboard with the newest BIOS sent to me from MSI Australia, I've installed the VIA 4 in 1 drivers, and can't see what I'm doing wrong? <br>
    I'm running win200Pro with SP1, and I know that it seems to be a bit of an overkill with ECC memory on the windows 2000 system. Win2K is suposed to have a software based error corecting..eh..thingy..but my system is running sooo much smoother with the ECC RAM it's unbeliveable!!(used to get 5 bluescreens of Kmode_exception_not_handled A DAY!)<br>
    <br>
    But I'd like that extra 256Mb of RAM though..and by the way, now that I have(soon?)512Mb of RAM, could I pretty much turn of the virtual memory, or just set it to like 2MB?<br>

    Mate , sounds like a case of some faulty RAM. Another thought that came to mind was that your mainboard only supports 128MB DIMMS but I doubt it. Try some other RAM.<br>
    <br>
    And when you do get it to work, leave virtual memory on , even though you'll use it much less you may still need it sometimes so leave it on to be safe. <br>

    Yes, you could try removing each ram module individually to see if you got a bad one.

    Hey guys, and thanx for the response, I did as bugsy sugested and the results are one of those that will go down in history along with the questions such as:n Is there a God?, How do women think? What's naval fluff actually made of ,..you get the picture... well here goes: (please note that when I talk about 262MB it actually means 258 MB(262000KB/1024 =258MB)likewise 131MB =128)(I just now how it works, not why it works)<br>
    <br>
    Mem bank memory <br>
    1 256ECC<br>
    2 128 non ECC<br>
    3 256ECC<br>
    <br>
    Reported memory: 131072KB of memory!!!!(I had turned of the ECC function by the way, but when I saw this I turned it on, restarted, and the result was the same, 640MB or RAM had shriveled into 131MB.)<br>
    OKIDOKI I thought to myself, now you've just fried 512MB of RAM you idiot!<br>
    So I took out the 128 non ECC, restarted, and voila! 262MB of RAM.<br>
    <br>
    I took out one of the ECC sticks, back to 131, exchanged that one with the other ECC stick, and the same result again..131MB...<br>
    I swapped,flicked,pressed, pushed, swore, bled and cried,I swallowed an alphabet and farthed a poem...nothing helped.<br>
    <br>
    No matter what mem banks, and what order these RAM stick are put in, they are only half the RAM they should be.And if(God forbid) I tried boosting the 262MB that was posted with another 128 my puta quickly grabbed the 256MB and left me with the 131...again.<br>
    <br>
    OK..I've been rambling on for half an hour now, but this is a very emotional moment fo me..sorry.<br>
    <br>
    If anyone has a sensible solution to this vast enigma, plase reply. <br>
    <br>
    (I think I know what's' wrong, but I don't believe MSI will agree)<br>

    What you can do now is disable Virtual mem and restart.<br>
    Then Defrag your harddisk ( on which you put your swap file ) and then change your virt. mem. settings to MIN 512 and MAX 512.<br>
    <br>
    If you do that, your harddisk will take a solid spot on your harddisk for swap.

    Thanks for that GeforceAtum,I think I know what you mean but is'nt that just to prevent the computer from using resources resizing the swap file? <br>
    <br>
    Anyway, I've still got 262MB, instead of 512.. sigh..<br>
    Anyone else have any ideas?<br>

    If you stuck that ram in another machine and it came up like it should then it isn't the ram. Then try flashing your bios. Try updating the mobo drivers. Then take the mobo back.

    Are you sure the mobo can handle more than 256MB ram???<br>
    <br>
    The VIA apollo can handle 256MB <br>
    The i815 can handle up to 512MB provided that one of them is single sided<br>
    The Via apollo pro and i440BX can handle &gt;= 512MB

    Thank's for the support guys! OK, I tried putting the memory in a friends computer and his mother board looked at it, turnede it's back and kicked it out, I.e. it did'nt even boot up, but his motherboard is pretty ancient so I guess that would be the main issue there.<br>
    <br>
    Thanks for the support again, it makes it a little easier in this harsh and cold world of computer problems.<br>
    <br>
    In reply to Aris, the chipset is VIA(R) VT82C693A / VT82C596B chipset, I don't know which one actually, but there should'nt be a big difference between the two..<br>
    <br>
    I'll post another message as soon as I get my lazy butt down to the local Computer guru on the corner.<br>
    <br>
    Thanx again, <br>

    You have a via apollo. Not much you can do I really don't think your mobo can use more than 256MB of ram. But just to be sure check the mobo website for specs and support.

    Hi again, yes, well I did, and MSI has managed to mix up the MS6135va(=VIA) with another motherboard with an Intel chipset(!!) I.e., when I go to look up my Mobo, I get another motherboard's spesifications... kinda hopeless.<br>
    <br>
    Even if my mobo only supported 256MBRAM, it shouldn't have take half of my RAM when I installed the single 256 Stick, only recognising 128.<br>
    Is there a difference in ECC RAM? I've heard about 1 bit, wich my motherboard supposedly supports, but is there also 2 bit ECC, and if that's what I've got, could that explain it?<br>
    <br>
    I've been looking for stuff on ECC memory, but I've only seen turorials on what they do, not if there are different types of them..<br>
    <br>
    The compaq website won't give me support unless I've got the serial number to one of their desktop or notebook systems, which is VERY irritating and weak.<br>
    <br>
    Any ho, I'll check with this harware wizard downtown as soon as I can and give ya'all the exciting results..<br>
    <br>
    Thanx<br>

    There is the slight possibility that if there are 2 dimm slots and it only supports 256MB RAM, then perhaps the largest chip size it will support is 128. I've seen it before. I'd check on that.

    the only problem i see is that your using COMPAQ ram...maybe it's not fully compatible with your mobo <IMG SRC="smileys/cool.gif">

    Stop!<br>
    <br>
    Get a new mobo, via apollo is way too slowwwwwwwww.... <IMG SRC="smileys/knock.gif"> <br>

    Aris, I think your right...but what mobo to choose, I've been thinking about the ABIT K7 RAID, but that means going AMD, which I don't mind really..don't really care(just got to sell the CPU too then). I also heard somewhere( Cnet?) that mixing an Intel cpu with a via chipset is asking for trouble..any thoughts genlemen?<br>
    <br>
    What is the best (affordable) motherboard today, or rather,what's the best chipset as you see it?<br>

    Just as a thought... i had the same prob with 512MB of Non-ECC mem on an intel nightshade board (N440BX). Plugged the same memory into my KT7-RAID and Voila! 512MB of RAM. If you can get them, check the listing of compatible memory for your board from MSI. Probably does not support the ECC memory. I know the KT7-RAID does not. The memory i used was non-ECC and worked but according to ABIT it cannot handle ECC memory. Probably a case of incompatible RAM. The way you can tell is if the system runs stable even though it shows 1/2 your memory. Had an ASUS P2B-F that did this with the same memory but ran fine, just would only see 262MB (256MB for the layman). Otherwise it worked. The Intel Nightshade would not even boot. Get non-ECC memory and see if this helps. might work better as some Via based boards cannot support ECC. I think the 686A/B chipsets do not support ECC type RAM.

    euh, the Via Appollo Pro can do up to 768mb (3x256) according to my mobo book, and 3x 512 isn't tested but it should do it

    Yes many manufacturers claim 1.5GB of memory support for VIA apollo pro chipset. Asus comes in mind!<br>
    <br>
    Via based mobos are fine if they are from well respected manufacturers like ASUS or ABIT. Also you can use the latest Via drivers for less problems.<br>
    <br>
    If you stick with high quality components there shouldn't be any problems with either AMD or INTEL based system.
