I want to put 2x8 GB of ECC UDIMM RAM into my secondary computer (AsRock board with an ECC memory support and Ryzen 1200AF). I can buy these two used models from the same seller and for the same price:
The specs look identical. I will probably get the Hynix but if I should get the Samsung instead, please tell me why. Like I said I want it for Ryzen and also would like to overclok it a bit (to around 2666 MTS). I guess there is no way to find out which dies are on these sticks, right?
I have some Super Talent DDR4-2400 8GB/1Gx8 ECC CL17 modules (Samsung chips, possibly B-die?) from my now very old TR1950x system that I can sell you if you like as well. In that system they can reliably overclock to 2933mhz with tightened timings. I suspect they could possibly go higher, but the memory controller in the TR1950x just can’t handle it with all 8 slots filled, any higher and a few errors will show up in the logs every month or so, and 3200 quickly crashes. If you are interested let me know and tonight I’ll look up the info, come up with a price (I’m thinking ~$50 for two modules including shipping is probably reasonable, I’ll have to double check shipping prices) and make a dedicated “selling” thread for accountability.
Thank you. You are very kind. But I am from the Czech republic (central Europe) and shipping plus additional charges from the USA would raise the price quite a bit.
The links I posted are just for the specs, it is not the place where I want to buy the memory. I am buying it locally. The seller’s price for the 8 GB stick is 8.68 USD so roughly 20 USD for 2 x 8 GB including shipping.
I know, I just want to bump it up from 2400 to 2666 MTS or something like that. I think it should be OK. If not I don’t mind running it at the default MTS. It is not a “mission critical” machine but I just want to have a bit more reliability than I can get with a regular RAM. In my primary (Linux) machine I will be putting 4 x 8 GB new UDIMM ECC Kingston sticks running at 3200 MTS without any overlock nor tuning. This machine should be even more reliable.
There is no better ram to overclock than ECC ram. This is because you can prove there are no errors by checking logs, rather than running tests for a day(s) and crossing fingers. My ram would pass all tests just past 2933mhz, but would still generate several errors now and again every 1-2 months. Without ecc, (as in all “ OC gaming” ram) I’d likely not have been able to tell, and thus back off a bit with out something getting corrupted. And hey, if there is an error, it gets corrected anyway, so no big deal. There is a lot of performance left on the table with these 2133-2400mhz ddr4 modules.
The idea that there is something special inherently about ECC that means you shouldn’t overclock it is misplaced. If you are building bridges, then sure, leave everything stock and certified for legal reasons, but the vast overwhelming majority of us just have homelabs to fuck around with.
if they are the same price then samsung had the better ic with ddr4.
ddr5 on the other hand, there wont be much difference.
they both have the same cas latency? same MT’s? get the cheaper ones.
oh you want to oc the ram? better to get the ram speed you want rather than scrimping and hoping the ram you get will work at the numbers you have in your head.
sure it might work…
but getting the faster ram in the first place and maybe tune that rather than overclocking…
you get way better stability.
Dear lord… these guys are the total opposite of their name. They ought to be named “memory4more.”
The same people probably operate a bunch of other sites like PriceBlaze and Servers4Less. (Check their company info and all the complaints they’ve gotten on review sites. ) Every item I could find on those sites was at least double the price of what others were selling for. They sell refurbished/used for more than the MSRP of a new item.
