Old board..new RAM

Just wondering why this old Super Socket 7 Jetway MB I`m fixing, wont
recognize all of the Kingston (Value RAM) PC133 256 MB memory stick I bought
new for $36!
It does "see" half of it or 128MB but NOT the whole 256MB.

I know this board is only a 100MHz, but PC133MHz should and is working OK,
just not *ALL* 256MB of it!

The Spec sheet say: "Support 3 Banks SDRAM Main Memory, 8Mbyte to
768MByte"
"Support 3 X 168-pins DIMM Module..
(SDRAM)"

The 768MByte means to me, I could have a 256 MB stick in each of it`s three
slots, for a total of 768MB....NO?

Thanks for any input into this relic.
Matt

P.S. Got this mid tower computer and 17inch monitor for nothing, and so far
have only put about $50 (heatsink/fan and RAM stick) into it. Thats my
limit!

Well my first thought is, does the motherboard support double sided ram. I
have heard that if there are chips on both sides of the stick then the MB
will only see one half. Is this the case for you? I tthink it might be.

HTH.

Ditto or maybe even a BIOS update but I doubt it :/

Thanks for the quick response guys, but the one 32MB stick I took out of
this board has chips on both sides. The spec sheet says it supports 3
*banks*.... although, there are 3 slots!
Is there a way I can determine for sure whether or not this board will take
double sided RAM?

Thanks again
Matt

Most new 256MB 168-pin DIMMs are single-sided, with eight 32Mx8(256Mbit)
chips.
Old motherboards like yours, will not support single-sided 256MB DIMMs.
Your
board will require a double-sided 256MB DIMM, with sixteen 16Mx8(128Mbit)
chips.

Ok this is the concept I was talking about, I just had the rule around the
wrong way...

OK...Now I am confused! The 256MB stick of Kingston Value RAM I have
installed into this MB
*IS* a double-sided 256 DIMM, with eight (8) chips total, four (4) on each
side!
Read from one chips on the stick: 133x64c3/256

These are less common, but it is not supported by your board for the same
reason--it uses 256Mbit chips. This 256MB DIMM has eight 16Mx16(256Mbit)
chips. Your board is limited to chip densities up to 128Mbits. You need a
256MB DIMM has sixteen 16Mx8(128Mbit) chips.

Best bet is Crucial.com. Enter your MB and they'll come up with RAM
guaranteed to work with it. Reasonably priced too.


Plus it lets you know the specs of what type of RAM is compatible even
if you don't buy Crucial

According to kingston, KVR133X64C3/256 RAM is NOT backward compatible with
motherboards that only support Ram at 100Mhz.
What you will need is KVR100X64C3/256.
