ReadyNAS Duo v1 - Kingston 1GB PC2700 CL2.5 confirmed working

[st_1]

As a plan B for the Samsung 1GB memory SO-DIMM I bought on Ebay (from Hong Kong), I also ordered a pair of 1GB Kingston PC2700 SO-DIMMs (from Hong Kong as well). Total price of just under $9.

They too were advertised as CL2.5 (as was the Samsung). Most of the modules on Ebay were advertised in pairs, so I thought I'd give a pair a try in addition to the single Samsung.

The Kingston memory modules arrived yesterday, and eager to try them out I put them in the old Toshiba laptop for memtest86+ testing.
They checked out all ok after two passess of all tests.

Memtest86+ says they have 2.5-3-3-6 timing, in contrast with the 2.5-3-3-7 of the Samsung module and the original Unigen DIMM in the Duo v1.
Memtest86+ also report a slightly lower data-rate of these modules (960MB/s) compared to the Samsung ones (1194 MB/s).

Nevertheless, the Kingston SO DIMM seems to work just fine in the Duo.

EDIT: I should add that ReadyNAS Frontview reports the modules being 2.5-3-3-7 instead of 2.5-3-3-6.
I am streaming music and video of the unit as I write, so I experience no problems so far.
I will leave the module in the unit for at least a few days to consolidate my impression.

Module name: Kingston 2GB 2X 1GB DDR PC2700S 333MHZ 200Pin 2.5V SO-DIMM
Technial labelled as: KVR333X64C3A/1G 2.5V
Serial (assumed): 99P5471-013.AOOLF 0000005622821 81L62-8HXMTM-YRA2F

The Kingston SO-DIMM has been running flawlessly for over two weeks now.

I will conclude that they work just fine.

What performance improvement are you seeing?

[st_1]

Main benefit is that the (legacy) Logitech Media Server runs well now.

Previously, it ran into trouble scanning the media files (probably due to the number of items), and sometimes stopped working at all with my Logitech devices. Perhaps an in-memory database size issue?

NFS and SMB is as could be expected.

Streaming is more or less the same, but then again it was fine to being with.

I have therefore done no speed tests, so I can't really detect any improvement there.

(Audio is mostly mp3 <256 Kb/s, and video is MPEG2 or AVC <6 Mb/s TS bitrates.)

All-in-all: stil covers the house-hold's regular needs.

And still below 50% capacity used...

Pure streaming doesn't tax a NAS (even the older sparc ones) - even 4K is at most 12-13 MB/sec.  You might see some uplift in SMB/NFS speeds, but I'm thinking the whole point of this was to get LMS to work well.

Sounds like a successful upgrade - Thx for following up.
