[HECnet] DIMMs for a DS10 ?

[John H. Reinhardt]

We went through this back in September...


An update:   The Micron part number is correct also.   For a 512MB DIMM you want a MT18LSDT6472JG-10Exx.   The JG indicates the 200-pin DIMM so that's significant as is the -10Exx which specifies the 2CL CAS latency.

You have a DS10 so you don't have to be quite as picky. The DS10L needs a shorter DIMM board.   The old DEC/Compaq part number for memory was MS310-xA where A=64MB, B=128MB, C=256MB, D=512MB, E=1GB.   This is total size. Each kit is 2 DIMM boards so the largest is a set of 2 512MB DIMMS.

The trick about the DS10/DS10/DS20/ES40 memory is that it's on 200-pin DIMMs.   And if you Google or search in Ebay you'll get a ton of hits because it's a common notebook memory size for SO-DIMMs.   These will not fit. Be wary.   IIRC the basic spec is 200-pin, PC100, ECC but I can't remember if they're buffered or un-buffered (registered or not).


Okay, I pulled a DIMM out of my DS10L and it's DEC part # 20-01ESA-08 and specifically a Samsung M378S6450ATQ-C1H

Googling this tells me it's a 200-pin, PC100, Synchronous, CL2, ECC DIMM.

I found one hit on the US Ebay for memory fitting this specification, however, the picture they have with the listing is for a Micron DIMM board and the part number decodes to a 186-pin DIMM.   So either the picture is wrong, or generic or the listing is incorrect.   In either case, beware.   Alpha Memory 256MB 200pin Synch DIMM100MHz CL2 ECC

Your best bet is going to be searching on MS310-EA or 20-01ESA-08 and on the US EBay it looks like the best deal is
1GB (2x512MB) PC100 ECC Registered ECC 200pin Memory for $59.95 US.

It's an oddball memory and tough to find in the generic market.   Good luck.

Thanks for that - but what TYPE (MHz etc) are they, exactly? I was going to just buy generic RAM.

The DS10 uses the same kind of memory as the DS20(E) and the ES40. Memory must be installed in pairs and the maximum size for 1 memory board is 512 MB. 
Have a look at eBay Sampsa. Check the systems and options guide for the DS10 memory part numbers on the HP site

Guys, what kind of DIMMs should I be looking for on ebay to add ram to my DS10?

I'd like the largest possible ones so that I can fill it up to 2 GB.

So i've been (with Steve D's) help researching upgrading the RAM on my DS10.

The HP part number 3X-MS310-EA. From what I can gather, this is a kit of  200 pin, 100 mhz 512 MB set of DIMMs.

Would generic RAM do instead?* If so, what spec? Anyone got pointers to a site that sells them (pref. in UK or EU), or maybe wants to unload some on me?
