... snip Thanks for the reply, Paul. My CPU is an AMD Duron 1.2gig. I tried to find a tech support website for the motherboard, but couldn't find one. Do you know how any way in which I could find out if my motherboard will only accept registered memory (what exactly is registered/unregistered memory, anyway?)? Ah Ha! There's the reason why you cant run a 133 bus - Durons ONLY run at 100 MHz bus. As for the registrered unregistered part, registered memory has a chip on the module which provides information about the memory to the motherboard, non-registered relies entirely on the user configuring the BIOS accordingly/correctly - my understanding is that registered memory behave from a users perspective similar to what SPD (serial presence detect) offers. You may want to search the net for a more definitive explanation - perhaps the big memory companies such as Crucial may have something on their site about it. A URL to a manufacturer for that board is he http://www.biostar.com.tw/products/m...=M7VIG%20Pro-D In terms of getting it to work, I still think your best bet is to see if you can "downgrade" the modules to slower speed items and you won't have a problem (possibly a CPU upgrade to a 133 MHz bus Athlon *may* yield the same results).

Both slots can obviously support 1GB modules each. I purchased (2) 1GB memory modules. They are labeled as "1GB DDR333 Module 16C". When I insert one of them, and turn on the computer, I get a long beep (a few seconds), silence, then beep-silence, over and over again until I turn off the computer. If I put the other one in, the computer seems to boot up ok, but it's unstable. I can be using the computer when all of a sudden it just reboots on it's own. If I put both modules in, I get a ton of registry errors as it boots and the system loads, leading me to having to shut it down. I've contacted the place I bought them from and they have offered to replace the modules, but they insist that all memory is tested prior to shipping so it is unlikely that they are defective. The only possible cause to this whole thing is my system bus speed. It is supposed to be capable of running at 133MHz, but when I remove the jumper that the motherboard says I need to remove, the system won't even boot. With the jumper on the pins, the system boots, but the bus speed is 100MHz. Is it possible the bus speed is causing the problem with the DDR memory and does anyone know what I can do to fix this? Your board is a low-end make using Via KM266 chipset, integrated video. That the slots "could" in theory support 2 x 1GB modules may not matter, it is fairly common for that era of cheap board to not be able to run a pair of 1GB modules. frankly I'm at a loss as to why you'd want to anyway, it is a mismatch to spend so much on memory with a board having slower memory bus to begin with, let alone considering the integrated video. As for those memory modules, who knows? Lots of slimeball dealers will claim "we always test, you have to pay restocking fee"... I"ve even received PC1600 modules that a disreputable dealer SWEARS are PC2100 due to a fake inkjet printed label they stuck on, even when the chips themselves aren't spec'd for correct speed. Return the memory and buy from someplace guaranteeing compatibility, like Crucial.com. You might still find your board to be a poor candidate and might consider replacing it. |
