My 2.5 years old delidded 7980xe @ 4600mhz all core with 49ns memorylatency (4000c16 twekaed) is faster than 3950x max overclocked on water in every scenario. Pretty good for a ancient cpu
In gaming it has no chance vs my new 10900k @ 5400mhz and 4600c16 tweaked memory. ~35ns memorylatency.

I just did a 2700 non x msi b450 16gb (50$) kit @300 0 16/18/18/38 iirc for right around 320$ for a buddy coming from and i7 920. The 2700 was a messed up sale price on amazon prime day though (145-150?). You might literally be able to side grade for the same price selling off your old rig.

OP's current sig is with DDR4. He can use it and just ramp it up to 3000MHz.

I used to have a 5820K. In gaming, I did not see any difference between that and my i7 2700K, so I sold it.

This DDR4 kit refuses to go beyond 2666 CL15 on my X99 system.

Been reading ram speed does not really matter with Zen2. I guess those aspiring for 4000MHz and higher just want to see the numbers.

That's a bit misleading. As with everything, there are diminishing returns at a certain point.
TPU has a memory scaling piece on the 3900x https://www.techpowerup.com/review/a...ing-benchmark/
Generally, Infinity Fabric scales to 3600 MHz memory clockspeeds 1:1 and has a 1800 MHz clock then. Beyond that you can get it to 1900 MHz with some tweaking. Over that (so 4000 MHz memory clockspeeds) you need to run it decoupled from the memory clock and that accrues some additional latencies. So 3600 MHz / 3800 MHz is generally the sweet spot for Zen2.
Performance increases from 2400 to 2666 by about 1% in games and applications, and from 2400 to 3600 by about 4% to 5%. So just running 2400 or 2666 leaves performance on the table.

3700X/3900X is better than 2700K.
In gaming and everything else.

Just have not seen enough evidence since most reviewers either run tests on 3200 CL14 or 3600 CL16. Have not seen one using in between with tighter timings. Be getting my 3600 soon to replace my 1600 and will do my own test using some FlareX b-dies.

My 2700K is about as fast and powerful as my R51600, so i would imagine GEN2 is indeed faster than both. But at 4K, the difference would be almost none in the case of the op.

Hi,
Yep I have some corsair dominator 2666C15 and it is total crap too if yours is crucial as in system spec's

I bought on chance could of used it in x299 if it didn't work in x99 some trident-z 3200C14 and it works very well at rated speed and manually setting timings 14-14-14-34 1.36v
This set is samsung b-dies and x99 seems to like it a lot and so does amd so it's a win win purchase.

https://benzhaomin.github.io/bdiefinder/

But as I said before pick your poison ebay 450.us for a new 5960x and new 3200c14 ram is also a viable option for your x99 board.
Might save a little on another windows license...

That 2600X is faster than 5820k.
3900X is 10% faster in games @ 1080p than 2600X.


So much for the posts above saying the 3900X will be equal or slower than 5820k...
