I know for sure the DS10 memory is 200-pin because I just pulled one out and looked at it. Now I'll have to pull a DS-20 chip and see if they really are different. I thought they were the same also. John H. Reinhardt On 9/24/11 11:57 AM, H Vlems wrote: The memory is 168 pin SDRAM

DS10 memory

by healyzh＠aracnet.com

How close do you really need to be on the DS10? I've used some fairly out of spec RAM in my PWS 433au, and I believe even the RAM in my XP1000's is out of spec. Though the best is probably the old AlphaStation 200 4/233, in spite of what what the DEC spec's say, you can use 128MB 72-pin SIMM's (if you can find them).

It operates at 3.3 V. The CL 2 latency spec is important. Hans -- | Zane H.

Noob questions #42: RAM for DS10

by johnhreinhardt＠yahoo.com

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. John H. Reinhardt On 9/24/11 11:52 AM, John H. Reinhardt wrote: 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. Cheers, John H.

Anyone got a bootable firmware updater CD ISOsforAlphaservers?

Sampsa, I'll open up my DS20E (same memory) for 3rd party specs. -----Original Message----- From: Sampsa Laine <sampsa at mac.com> Sender: owner-hecnet at Update.UU.SE Date: Sat, 24 Sep 2011 15:08:58 To: <hecnet at Update.UU.SE> Reply-To: hecnet at Update.UU.SESubject: Re: [HECnet] Anyone got a bootable firmware updater CD ISOs forAlphaservers? When I speed tested the IDE drive against a 5 DISK (9 GB, RAID 5) BA265, I saw no performance difference. Test file was 100 MB of random data.
