Hello am wondering if i got scammed somewhat by OLOY ram those are the timing at 3600mhz

@ 1801 MHz    14-14-14-34  (CL-RCD-RP-RAS) / 85-631-469-289-11-5-75  (RC-RFC1-RFC2-RFC4-RRDL-RRDS-FAW)

 

 

Anyways to compare them to high end stick from corsair and gskill?

 

12700k at stock xmp enable and power limit removed

My GSkill kit of 3600 has a TRC of 88.  I recall seeing a couple other of the sub timings well over 100 as well.  Sorry, I'd have to reboot to check for sure, but TRC is definitely 88 on mine.  Your bandwidth and speed seem to be on par (actually you're beating my sig rig).  OLOY just takes IC's from Micron, Samsung, or Hynix and just puts their name on the heatspreaders.  It's the same RAM as any other brand with those IC's.  GSkill doesn't make RAM either, they assemble RAM.  Same thing OLOY does.  The biggest difference SHOULD be warranty / support and looks.

Now, back in the DDR1 days there was a formula you could follow.  IIRC TRC = RAS+RP / TRFC = TRC + RCD, or something along those lines.  Was the same formula for DDR2, and I thought DDR3 too.  DDR4 seems to have significantly looser sub timings.  Anyway, what I'm getting at here is that those formula's don't seem to work with DDR4.  I'm sure somebody has written up proper formulas to calculate DDR4 sub timings, but alas, I don't know them.

Got a lot of reading to do on those timing setting and tweak.

 

Happy to hear my result are as good as your!

 

Yea i know about ram chip only crucial  is owned by Micron all the other just buy them from random manufacturer.

 

I saw a post on oloy mobile ram performing worse than higher timing corsair and kingston ram the oloy subtiming was so high that cl21 ram was faster than oloy cl18 with same clock.

 

I wonder if 3800 c14 would work in gear 1.

Need to read more on gear 1 and 2 and voltage for ddr4.

 

Ram run at 50c already.

 

😁
