Some more chips.... Intel ark but summery available as well below.

Embedded Pentium D and Xeon D CPUs released

Some 20 and 25 watt TDP 4-cores... I guess Intel are making some models as requested by OEM for specific devices as well since some of those cpu's don't make any sense at all for general compute.

Is there a list of memory modules that are known to work reliably - based on manufacturer claims, reviews, or users' practical experiences - with the first or second generation D15xx Supermicro boards? I've looked but cannot find one in this thread or elsewhere.

On Supermicro's page for a mainboard, under "Links and Resources" on the right-hand side, there's usually a link to a RAM HCL.

But the funny thing is, those links seem to be missing currently. I know for a fact they were there a couple days ago. Hopefully it's just a temporary website glitch.

Agreed that they usually exist but don't today for some reason but thanks for your comment.

Additionally though Supermicro's list of tested memory is usually very short. People have probably used other memory without problem - that would be an interesting resource and is part of the reason for my question.

Don't suppose anybody has compiled a list of stepping's for the Xeon-D ?
Just wondering what is our there.

Confirmed working! Take extra extra care of the exact SKU code while ordering/after receiving. Double check it. My experience so far is that the suppliers will make mistakes with the SKU codes.

- Samsung M393A4K40BB0-CPB (32GB / RDIMM / DDR4 / 2133-2400 GHz)
- Samsung M393A2G40DB0-CPB (16GB / RDIMM/ DDR4 / 2133-2400 GHz)

@Evan we do have a board for review but it came directly from Taiwan.
Any chance for a power test in the next few weeks ?
Otherwise looks like all SM for me but I would wait if I thought these SFP boards would be lower power and mini-itx with SFP 10G

Now that there are 1518, 1520, 1521, 1527, 1528, 1529, 1531, 1537, 1539, 1540, 1541, 1548, 1557, 1559, 1567, 1571, 1577, 1581 and 1587, are there any other differences between these than the number of cores, the frequency, the TDP or the presence or absence of turbo? Were some of these supposed to be "networking" units and some "storage" units? I guess 1520 is replaced by 1521 and same with 1540 and 1541.

For a simple NAS, what should I aim at? A 1508, 1518 or 1521?

Mostly marketing differences. There are some like product lifetime (e.g. some chips will be available longer than others) but those are probably less of a concern for STH.

Of those three, I am a big fan of the D-1518. I have not gotten the 1508 yet. The D-1518 has a decent amount of raw CPU power at a lower TDP. Plenty of CPU power for a NAS.

Just got my X10SDV-4C+-TLN4F and none of the sensors are working (showing not present). I tried resetting the IPMI device but still nothing.

Not sure if anyone has seen something similar?

FIXED: I had to boot into an OS first...odd is that normal with the xeon-d line? You don't get sensor readings till booted into an OS?

On a side note...the included fan is pretty loud (whining?). Spins at 6600RPMs. Setting the fan speed mode to "Heavy IO" reduces it by quite a bit.

I'll agree on this one. I just replaced a the MB/CPU (X8ST3-F + L5640) in my NAS with a X10SDV-4C-7TP4F. Power usage dropped about 100W according to the readout on my UPS (now stands at 120-130W with 11x4TB drives). I'm eying a couple of 1508's too to replace my current VM cluster (2x1508 + 1x1518 should be plenty for my needs).

When I look at low power VMs I would maybe think about the D-1528 to stay low power.

RAM, chassis, drives and etc get to be expensive, as well as licenses (if applicable). 128GB RAM with 2 or 4 fores might be a little bit of overkill. If you can get 6 cores / 12 threads on the D-1528 v. 2 cores/ 4 threads on the D1508, you are probably going to come out ahead cost wise with the D-1528 after all of the system bits are considered.

I Guess he needs minimum number of nodes for clusters like vsan ? But cheap as the 2 core is the 4/6 core do seem to make more sense still. Something I was struggling with but just picked up another d-1540 cheap so although power is a little more cost wise is made lots of sense.

Look what I just got today!

A Gigabyte MB10-DS5 engineering sample. That's a Xeon D-1581 with 16-cores/32-threads with 2 x 1GbE and 2 x 10GbE SFP+!
Goddamn it. I've been patiently waiting for the 8 core, and you tease me with this!

Back to waiting I guess :p. That heatsink looks nice and chunky though. I approve.

Oh sorry.. gotta go change my pants.. Thats some nice hardware :)

Does it really just hold 6 sata ports?
