so i ordered me another stick of ddr4 (kingston KF432C16BB) with 16 20 20 timings.
seller sent (KF432C16BB1) instead, which has these timings 16 18 18.
the system works ok for the most part, except under load i notice apps can freeze, which didn't happen with previous hardware.

memtest came back with no issues. should i get a refund or stick with it?

its running at the wrong speed, you're gonna have to set it manually in BIOS.
>>
>>103038175
are you referring to frequency or latency?
>>
>>103038199
both.
downclock it to 1200mhz 18 17 17 39 to get a match.
but now you have slower memory so send the thing back and get the indentical stick so you get back to XMP-3200
>>
>>103037838
That's why I only buy Crucial.
>>
>>103038223
He would be better off running the 3200 speed at 18-20-20 instead of clocking down.

Do yourself a favor and stop being cheap with your purchases.
Even if that means you don't get Thing you want tomorrow. Or next month.
You'll be a lot happier with your decisions.

OP here is why your RAM will be fine with matched settings, even with unmatched sticks.

Manual OC it.

>>103037838
the 16-18-18 kit is nanya RAM
what does the other slots say?

most based post of the week award
this setup looks like a fucking candy cane but it works great

(not a good idea on DDR5, sadly)

bump.......

just match them in bios, pretty sure even the shittiest dram chips can handle 16-20-20

i'll try to match them. was waiting on the seller's response, they won't be able to avail the original (KF432C16BB). i'm always leery of overclocking, but i'll give it a try while it's still returnable.

originally i had 4x8gb 2400. i picked up 16 gigs few months back, then the second came in this week when it was back back in stock. hoping for a slight performance boost, but the mismatched timings threw a wrench in my plan. the system is running 3900x on asrock b450m steele legend for reference.

i hear you, but i have 4 computers at home that i use for rendering. an upg-rade for me is adding a new pc to the render farm, and i always che-ap out on components except for the cpu. the ram sticks particularly have been swapped between systems like a college hoe since 2016.

>>103040302
um. SK Hynix?


>>103042584
appreciate the bump.
>>

so you're mixing RAM from two different manufacturers
that's not gonna work well

your sub timings are weird for running quad singles and your voltages are a little unchecked for that speed
Also that practice of crushing tRWR out of step with CL and RRD is weird and yields next to no benefit for the hassle

1.45v basic ass OC
>>
>>103043186
you have samsung B die while he has micron rev E. the timings are different.
>>
>>103043186
>your sub timings are weird for running quad singles
you mean good
they are bottomed out, lower doesn't POST
tWR/tRTP can only go lower with 1.55 V and even then i haven't gotten that fully stable (probably gets a little too hot with 4 cramped sticks and no fan)
>your voltages are a little unchecked for that speed
i need 1.5 V for tCL/tRP 14

>>103037838
YOU MISSMATCHED RAM YOU FUCKING RETARD!
YOU COULD SUFFER SEVERE DATA CORRUPTION AND DATA LOSS!!!!!!!!!!!!!!!!!!!!!!!!!
