hi all,

i got hyperx savage 2133mhz cl 13 overclock to 2666mhz cl14 and this is my result in aida64 memory test

RAM.png


83ns memory latency?? am i dreaming or what?

im on asus prime X370pro with ryzen 1700

ram is KHX2133C13D4/8GX and aida64 tell me manufacturer is SK hynix???

anyway i start thinking my ram suck hard should be like 34 ns or what ...

can some one help?

thanks

Higher timings increases latency.

You won't get 34ns even with the latest & greatest OCing monster in 8700k, not at 2666 MHz & CAS 14. What you're seeing is right & fairly accurate, if you want lower latency then you'll have to increase the ram speed (with the same timings) or tighten the current timings @2666 MHz.

but im already at 2666mhz in cl 14-13-13-36 which are very short timing right? i always think 80 ns is high latency dont you?
No it's not, IIRC Ryzen works fairly well with CAS14 @3200MHz, of course it's usually Samsung B die.

Like I said, for that RAM speed & CAS14 it's not. There's two ways to reduce latency, increase your mem speed with the same/similar timings or tighten the timings.
EDIT: just look this link https://www.memorybenchmark.net/ram.php?ram=Kingston+KHX2133C13D4/8GX+8GB&id=7968 it show my ram score comapred to other

WTF??!! the Kingston KHX2133C14D4/8G 8GB wich is cl14 is only 24ns im not understanding anymore
Why are you comparing passmark with AIDA64 :wtf:

anyway you can see the difference of NS latency on my link, mine got 82 and all other like 32 its not about program in background whicj i already shut down,

its about the bench result on my link, u can clearly see my model got higher latency than the other

the Kingston KHX2133C14D4/8G 8GB which is exactly the same than me exept it got LONGER timings (cl14) instead CL13 for me got 32NS while my model is bench at 82NS.

i cant be more clear, i think my model is a bad model heve got a X the end of model number think thjis is what change

Placebo effect dude. You wouldn't be able to tell the difference in real world. Not happy with 'em? Send 'em back and spend moar!

Thats the list WITH Amd cpus as a comparison , and even there, lower speed, lower latency, higher speed = higher latency, those are guided by the laws of physics and the processes used to design and produce chips , only a next gen tech is budging that from our reality, ie massive bandwidth architectures like HBM.

Crazy overclocking can reduce it marginally.

youre right, one billionth of a second seems nothing. and after some search its seems have no impact on performance.

im just worried to see, than gta 5 run less good on r7 1700 3.8ghz than with my i5 6600k @4.5ghz, intel win the game this time, so i was lookin for any issues who can resolve my fps drop than i havnt before.

thanks for the link its all clear now, all 2133 got this latence, it seems cpu or platform imposed this , next step will be the b-die 3200mhz :p

Try to get 4.0 from the 1700.
