Ok i'll confess i'm super out the loop. Thinking about updating the system since having some kids derailed a lot of time which was going in to building custom case etc... I'm thinking about bumping from my current 5950x to 9800x3d. I'm so out of touch with things but thinking of ordering the following DDR5:


Probable motherboard Strix 870 F.

Opinions please, I've had Team Group before found it to be pretty solid, currently using said kit on my 5950x/Formula VIII. If its of any importance GPU is a 3090, PSU 1200w Thor, primary use daily work, gaming and occasional CAD/Graphic design.

Appreciate any swift links to comparisons or any recommendations.

Cheers,

want to go for CAS30 for AM5 Ryzens tbh

c38 at 8000 is technically less than c30 at 6000

Anything above ddr5-6000 (6400 if lucky) requires running memory controller in 1:2 mode. At 8000 it could be synced with inifinity fabric at 2000.
Meaning ddr5-8000 could be tuned to pretty low latency together with obviously high bandwidth

But should be warned that getting DDR5-8000 to run on AM5 is not guaranteed and will probably need manually setting timings and/or voltages. And needs a good motherboard (which Strix should be)
Alternatively dropping speed, at which point a regular ddr5-6000 is better. Besides 9800X3D is pretty indifferent to memory latency anyway.

I suggest you only go this route if you enjoy fiddling with memory settings. Very low likelyhood it will just work with turning on XMP.
 
Interesting- thanks for the quick info.

Does anyone enjoy getting memory stable? lol… I’m tempted but actually it occurred to me to check with the latency as you mentioned I’ll do some reading for sure.
 
With the 9800X3D, you'd get better value buying Crucial's basic 48GB kit for ~£100 and putting the other £100 into the graphics card.

Note that for heavily multithreaded work, this would not really be an upgrade.

£100 is irrelevant for GPU upgrade on a 3090 hehe. I can see some decent kits some CL26 so assuming this is the aim to tighten the timings on 6-6.2k…

Too old for memory stability testing, it's so boring. I went for 2x32GB of 6000/C30, dialled in Buildzoid timings and called it a day.

The cost to benefit of the C28/C26 kits isnt there unless youre chasing benchmarks.

X3D chips really aren't all that sensitive to that sort of thing, you're spending a lot more for little to no gain.

A £80 32gb set would be more than adequate, the much cheaper 48gb set mentioned by Tetras would also be fine.

I might do the same but will have a more detailed look if I can squeeze the timings for a little more cash all good…

I understand it’s a boring task been there done that just fell off the game a little :)

Appreciate the comment need to think about whether I even need 48GB but since I’ll be updating a lot less than previously might be a nice idea
