best ram for 9700k

[diabloinfinnity]

what ram should I buy for a 9700k? 

im getting my friends 9700k and was wondering what ram I should pair with it to get as high fps as I can in games like pubg and Escape from tarkov and battlefield ?

worth getting 3600 cl16?

its coming with 2666 cl15

RAM on Intel isn't really a factor. Definitely not for fps anyway. What's the price difference between those?

if you are trying to squeeze the most frames on top of a 5ghz 9700k, you'll need a motherboard with just 2 dimm slots,

falling short of that, something like a aorus ultra or taichi/p9 with 4 sticks of ddr3600, then further overclocking them, (the z390 elite doesn't guarantee 3600+ on 4 sticks)

possibly something like this if u wish to go all out with a 9700k+2080S/ti,

 

ram matters for tarkov, it very frequently caps out 1 core causing dips,  you would have to mitigate those frame time with the most from all ur components, still, gpu is the most important.

note that 4dimm doesn't improve performance for all games but never slows it down either.

 

I'm contemplating a 4dimm setup atm, leaning toward a 4x8 3600 oc 3866 config

Wasn't it in one of Linus's videos that 3200's are optimal?

Personally I WOULD suggest those (got them myself): https://www.gskill.com/product/165/170/1535961634/F4-3200C14D-16GFXFlare-XDDR4-3200MHz-CL14-14-14-34-1.35V16GB-(2x8GB)

Would, cause in your case, since you're getting a build with some memory already, I'd advise not to buy anything and try overclocking them instead. Depending on how your lottery goes you might not need to buy any sticks to reach the speeds you desire.

I would say 3200 is better deal since it's a lot faster than 2666

Also, I calculated cas for you,

Cl16 - 10

Cl15 - 11,2

So, the Cl16 ram have better latency, deffinitively get that one.

Could you elaborate on that part, please?

I was always of the impression CAS latency and CL is the same. What did you calculate and how?

I even looked it up and table on wiki seems to match one of your numbers when referring to 1st word transfer time (https://en.wikipedia.org/wiki/CAS_latency) and if that's the case I don't see how higher latency would provide lower transfer time...

(CL / Frequency) *2000 is formula for calculating latency. It is mentioned in one of TechQuickie videos

Crucial Ballistix Sport LT  -3200mhz cl16 : not uncommon to reach even 3800-4000 MHz @CL16 . They are Micron E-die sticks, with great potential for overclocking 

[Kalm_Traveler]

Generally 3200mhz CL14 is the sweet spot for Skylake-architecture-based CPUs in my experience.

 

I went for 4000mhz CL17 on my new 9900ks rig mostly just for fun. Was running 3200mhz CL14 on a previous 9900k rig and honestly I can't tell any performance difference. I tested that 9900k rig with 2666mhz CL15 and could tell it was a bit slower than the 3200mhz CL14 though.

Thanks.

Seems you made a mistake calculating the second one, then - and that's where my confusion came from, because it really wouldn't make sense to have a higher latency with lower CAS latency(CL).

I was able to look into it further and found this site: https://notkyon.moe/ram-latency.htm which uses the following formula:

( 1.0/( dataRate/2.0 )*casLatency )*1000.0

This is basically the same as yours, just written in a hellish way for whatever reason.

But even looking at it mathematically you can see that the lower numerator (CL in our case) the lower the end result will be.

For 3200Mhz and CL15 it will be 9.375.

May be I maded a mystake when typing numbers here from calculator, but what chanches are
