Hi,
Been lurking for a long time and finally decided to post a question to the glorious users of Vogons. I'm trying to "max out" or at least fill my 486 motherboard with as much memory as possible and I'm running into problems.
My hardware is:
M-tech R418W2, Award bios REV: Kw
CPU: Cyrix 5x86 120
No hard drive or any other devices as of yet
Anyway, my issue is this motherboard just basically refuses to properly recognize the memory I put into it . This board has 8 30 pin simms and 2 72 pin simms, supposedly you can mix them and the one or two manuals I've found online say that you can. The "max amount" of RAM is supposedly 256 meg (8 x 16 meg 30 pin and 2 x 64 72 pin simms).
I can't even load any 72 pin simms unless I load 4 megs of 30 pin simms in one of the slots. If I don't load any 30 pin simms, it flat out wont recognize the 72 pin simms at all. And when it does accept my 72 pin simms, it always recognizes them at 1/4 of the value they should be (very weird). So for 72 pin, I put a 64 MB simm and it only says 16, 128 MB simm and it only reads it as 32 (even though this board supposedly doesn't even support 128 meg simms). It wont boot period if I use EDO ram as far as I can tell.
The max amount of RAM I've successfully been able to POST with is 84 MB:
4x1 MB 30 pin (4 MB)
4x4 MB 30 pin (16 MB)
2x128 MB 72 pin = (recognized as 64 MB)
Anyway, does anyone have experience with this board? Is there a bios setting or jumper or something I'm missing here? I 'v tried so many different 30 pin and 72 pinn simms combinations and it always gives me the same weird issues with only recognizing 1/4 the size of the 72 pinn simms.
Thanks!
