3200? 3600? 4000?

[Cavallino]

Putting together a rig with an i9 10900K.
Thinking of pairing it with an MSI Ace.

Thing I am confused about is the memory speeds vs memory timings.
Some people are saying to get the fastest possible speed. Others are saying timing.

What is the standard clock typically for the above (without overclocking) Is it 3200? 3600?

Thanks. Is there much difference between these aside from the timings, The Viper has lower timings but does it really make much difference?

Is it worth going higher on frequency or just stick with 3200MHz?

What's the use case for the build?

Hi Guest2! Gaming/Internet/Email/VR etc.

E: thought I posted a response! Sorry!

I can see many people saying go for a 3600 but the Vengeance I am after has a high Cas value in 3600 (64GB) compared to the equivalent 3200.

Which should I go for?

Why do you need 64GB RAM for gaming, internet and email?

purepc.pl have tests for frequency with standard timings, but I can't find anything for frequency versus latency. I'd imagine any older benches would not be relevant either, since they'd have to test with the new gen of GPUs to still be relevant.

TPU have an analysis for the 8700K, which is the same architecture and a notch lower timings seem to be equivalent to 200 Mhz in frequency.

May I ask why you are answering a different question ?

Just futureproofing G2. Never know I may dablble in some more RAM intensive stuff later.
Im making a big build right now, thought Id go all in.

Cheers G2, appreciate your insights.

Ah cheers Tetras, so lets say a C16 3200 vs a C18 3600 would be a much of a muchness really?

I was responding to your use case.
Futureproofing with 64Gb high CAS RAM is a bad idea imo.
High CAS 3600mhz 64GB will not be as fast as low CAS 3600Mhz 32GB.
At the moment even 2x8GB low CAS is going to be better than 32 or 64Gb maybe unless you play FS2020 which uses more than 16GB RAM.
In 5 years time there will be low CAS 64GB RAM, or maybe it wont be needed but there will be 32GB DDR5 8000Mhz.

DDR5 is just around the corner, 2022 I expect. This will bring a whole new raft of RAM and RAM speeds

Cheers G2. Yes I am playing FS2020 for sure (another reason why I wanted higher RAM but appreciate there are diminishing returns at a certain point, even with FS2020).

So as a minimum I am going to be going for 32GB for sure, thats my benchmark.

The Vengeance 64GB 3200MHz stuff I posted earlier was C16, The equivalent in 3600 is C18, I guess the increase in latency vs the increase in clock surely should be same/similar?

Is it worth to go even higher clock speed if available? (doesnt seem to be much on offer at 32GB @ OCUK?)

Yes, probably about the same. It is worth it if the timings don't go up!

Keep your eye on this thread - https://www.overclockers.co.uk/forums/threads/g-skill-announces-memory-for-amd-5000-series.18905430/

4x8GB 3800 CL14 memory sounds great (Gskill F4-3800C14-8GTZN)

I expect it will cost a lot but you havent listed a budget, so skys the limit right
Maybe try looking for a CAS16 3800Mhz kit aswell, then you can hopefully lower it to CAS14

Cheers G2 I think Ill stick with the aforementioned for now and then I can upgrade to faster speed later if necessary!
