View Full Version : Need help - Memory for Biostar 8500TUD Mobo?

October 25th, 2013, 04:47 PM
Hey guys,

I just bought this mobo. For case logistic reasons, I can only use the DIMM slots. I found the manual, and is states the following:


DRAM Access Time : 3.3V Unbuffered SDRAM 15ns required.
DRAM Type : 8MB/16MB/32MB/64MB DIMM Module (168pin)

Problem is that for the LIFE OF ME, I cannot find 15ns 3.3V 168 pin memory on eBay. Also, can anyone tell me if I an use P100 memory, or do I have to have P66? It says "15ns required". I have found 10ms memory. Will that work?

168 pin SDRAM is usually found as PC100 non-registered unbuffered RAM in 15 nsec, or PC133 in the 10 nsec. variety. You can use PC133 in place of PC100 in almost all cases. It's as common as dirt on eBay--and cheap, particularly in the smaller sizes.

Just make sure you don't buy registered server DRAM--it won't work on your board.

Chuck. Could you do me a favor and link me to so memory on eBay that would work?

I'll do you one better... PM me your address and I'll send you a few sticks.

Well, okay--here's one (http://www.ebay.com/itm/MICRON-64MB-PC100-SDRAM-MEMORY-168-PIN-MT8LSDT864AG-10BD2-/181245534097?pt=US_Memory_RAM_&hash=item2a33135f91) (you didn't say how many you needed). PC 100, datasheet is here (http://download.micron.com/pdf/datasheets/modules/sdram/SD8_16C8_16x64AG.pdf).

It's cheap enough that you can afford a mistake. There's also a similar lot of 4 (http://www.ebay.com/itm/Micron-MT8LSDT864AG-10CB4-PC100-64MB-SDRAM-LOT-OF-4-TESTED-/200901623055?pt=US_Memory_RAM_&hash=item2ec6ab7d0f) for a sawbuck, shipped.

Note that I'm basing this on what I can tell from the very sketchy Biostar datasheet.

It's a 430TX board... those things typically weren't all that picky.
