help identifying a 5 year old micron computer...

[Conroy9]

Hi, my friend has a Micron Millenium computer from 1996, with the model # M55HIPLUS2-P200-CR, and he is trying to buy memory for it.

Crucial does not list that model. My guess is that it's the Millenia P200 (Plus series), but I don't want to tell him to buy the wrong thing.. I'm 3 timezones away so I can't look at the computer/ram myself, and it'll be a big pain to ask him to read off the numbers inside for me..

Does anyone have any idea what model that number corresponds to? thanks!

You seem to missing the Model Number, (MME, etc) but looking at the part number, here's my best guess:
M55HIPLUS2-P200-CR

THe 55 represents a P55 core, an Intel MMX CPU. THe P200 means 200MHz (duh)

Based on that, this is what I think to be the closest match:

Kingston Link

You can take the Kingston PN and search for it on Pricegrabber, you will find the best price on that module.

Hope that helps..

eh.. i had a micron millenia p200mmx.. that thing took pc66 sdr

THe problem is.. is finding TRUE PC66 memory. A lot of the PC66 that's being sold by your standard online vendor aren't true PC66, it's PC100 with the EPROMs reprogrammed to report PC66. It's not a "PC66" or "PC100" issue, it's a module density issue. He should stick to something like Kingston for this application, it will work.

I'm also looking that that part # (I'm assuming that was taken from the motherboard?) and I'm being lead in two different directions.

I agree with SuperSix that this probably takes a P55 core and is a P-200, but then Micron used a series of motherboards called M55Hi with revisions A, B, and D (list is seen here). The MME model doesn't use these boards but the MXE model uses the revision D. According to that page (click motherboard), it should take FPM or EDO but doesn't specify pin count, but that should be doable by inspection.

I'm going to go out on a limb and assume it's 72-pin EDO or FPM SIMMs since it uses the Intel 430HX chipset. I never saw an HX chipset using DIMMs.

ah he says it looks like 72 pin
Thanks a lot for the help!

How can I check whether he has EDO? will there be any problems if he adds EDO chips if the ones he has are FPM?

The only real way of seeing what modules he already has is to look at the chips and see if he can't find matching manufacturer specs on the web. On occasion, the memory modules will have a sticker applied that identifies the type and speed, but this isn't guaranteed and who knows, some shady retailer could've slapped a EDO 50ns sticker on a FPM 70ns module. Chip ID is the way to go.

After a bit more digging, it seems like the M55HI-Plus is a Micronics (Diamond Multimedia owned) manufactured board. I'm not sure where the "2" comes in, but it certainly matches the specs on the Micron website. Micronics M55HI-Plus (PDF). According to this, EDO and FPM modules can be mixed but it'll default to the slowest memory rating for all modules. If you already have FPM, the EDO cycle would be wasted if EDO is added.
