32GB Samsung DDR4-2133 Reg ECC $168 ea qty avail

[MiniKnight]

Looks like this seller has lots of these things M393A4K40BB0-CPB Samsung 32GB PC4-17000R 2Rx4 DDR4-2133 ECC REG Memory | eBay

$168 ea is a nice price. Cheapest on newegg is $203/ea. That may not seem like much but it's $35 module which adds up when you have 8-16 in a server. Enough to buy a spare or two.

Sometimes there's 1-2 that go for less but this is a quantity of the same module and they're Samsung.

@MiniKnight thanks nice find

@i386 - I had no shipping cost on mine?

Shipping is $124.05 to Norway.
Might be possible to get a better rate with jetcarrier or something?

Any drawback of using this instead of HP branded ram in a DL380 gen9 server?

Only if you use more than 1 dimm per channel.
HPE I believe uses the XMP profile slots in the spd chip to house enhanced memory profiles for qualified dimms. Normally as you increase dpc count frequency drops but with tested dimm sold by HPE they hold the frequency higher I believe going down one notch at 3dpc instead of 1 at each 2 and 3.

any problem with dell servers especially the t630?

Thanks,

Unless some error logs non-branded parts in the server or other drawbacks I'm not familiar with,
I don't see why I shouldn't go for this offer as it will save me £220 pr. module.

Just to confirm, HP does this:
2133 MT/s for both HP and 3rd party at 1dpc.
At 2dpc HP stays at 2133 and 3rd party drops to 1866.
But with 3dpc both HP and 3rd party drops to 1600 MT/s.

To prevent being too verbose I'll just post the link to the Best Practice Guidelines from HP.

Basically 1dpc in all 4 channels pr cpu should be ok both in terms of latency and throughput.
See table 2 page 5, figure 6 page 15 and figure 8 page 17.

That is correct.
Theoretically... if you understood reading and flashing spd chips... there would be no drawbacks ever.

Wouldn't the spd chip be write protected? (on these samsung modules)
Or would thaiphoon burner be able to "fix" this?
Anyhow, I don't think I'll bother to do it as I don't need more than 1dpc at least for now.

Also, the price on this offer, at least for me, is not that good.
Shipping is one thing, but the cost plus VAT equals the normal price here in Norway.
And that gives me brand new modules plus 5 year warranty.

idk... It has been years since I flashed cas settings but I did so in linux without a paid for tool.
I also don't know that is how they are doing it... just my best untested hypothesis.

The price was below this about 2 months ago; retail prices have spiked 30-40% and second hand prices have tracked about $20 higher. No more than a month ago were used 32GB registered DDR4 sticks in the $135-140 range.

I'll probably just wait this out.
