New motherboard does not recognize new memory

[mkemmerl]

I recently purchased a Tyan S2390B and a Duron 1000. I am using Win98 SE. First time I started after installing everything, it booted with no problems, installed the components properly, etc. The first thing I noticed was that it only recognized 64mb of my 128mb SDRAM. I have a 32mb/pc66, a 32mb/pc100 and a 64mb/pc100. The 32's showed up fine. After rebooting, the Registry Checker came up. It did it's thing, but started looping always saying I had a registry problem. Microsoft says this is a memory problem, but their solution didn't help. I have tried each of the Dimm's in each slot, but only the 32mb/pc66 works, the others give me the long, bad memory BIOS beeps. I was able to get to a command prompt, rename scanreg and then boot to Windows. I bought a new 256mb/pc133 stick and it also does not work.

Anyone have any thoughts?

Thanks!

Hope you got a lifetime guarantee on the Memory. Who makes the memory? You didn't buy cheap generic memory, did you? Maybe the place you bought that from will let you trade that memory in for a different brand. Also make sure the memory is the right kind for the motherboard. PC133 memory may not work in a DDR memory motherboard.

I usually don't have problems with Micron Memory from

Sometimes they have free next day air shipping on memory. If you do not like my post feel free to point out your opinion or my errors.

My thoughts.

Do NOT use that OLD memory. Period.

Follow ceh4702's advice and buy a stick of HIGH-Quality
RAM from Crucial.
Take back the junk you bought that wouldn't work.

Last: Find a good professional PC mechanic.

> You do your software thing, and leave the mechanical aspects to a hardware guy. You might have paid a little more to have your machine put together, but it would have been up and running a long time ago, and you wouldn't be here.

Here is a question for you: Would you use Windows 95 (Original version) software integrated into Windows XP, along with some Windows 95 B version ?

Of course you wouldn't. However, that is exactly the kind of thing you were trying to do with that antique ram, and you were using 3 different types..... or at least 2.
That RAM is out of spec, and disimilar to each other. It belongs in an old 66 MHz computer, and in seperate computers.

Thanks for the help. The 64mb is PNY and the 256 is KByte from Best Buy. The one that works is from an older IBM PII Aptiva. The other 32 I'm not sure about. All 4 work in the IBM, so I would be surprised if any of them were truly defective. The Registry Checker comes up even with the one dimm the MB does recognize and MS says that problem is due to defective memory also.

Best Buy. You answered the question that ceh4702 asked about "cheap generic" RAM, I guess.

A tip for all: Don't buy computer parts (that you expect to be high-quailty) at a place that sells washing machines, toasters, beach balls and paper plates.

Tip 2:

http://www.crucial.com

for your memory needs.
I buy memory almost exclusively there, and I say exclusively, only because they don't sell what MICRON does not make, which is RAMBUS RAM. Micron also doesn't make PC2700 DDR, but that doesn't really matter anyway since it doesn't improve the performance in an Athlon platform.
