What's the likely performance uplift from all the tweaking compared to dropping the CPU in and setting a XMP profile? Are the gains worth the time invested?

Depends on what your RAM is, in 2 ways.

My Motherboard doesn't have my RAM on the QVL list so they have never been tested on my board, setting XMP i get very lose timings, 18-21-21-21-50'shomething, tRFC was near 900.

Really bad, i set them 16-17-18-38 tRFC 560, and i'm sure i could get them lower than that if i spent more time on it, They are Micron B-Die. Because of the lose timings i have gained probably about 5 to 10% in Games

If you get good Memory IC's, like Samsung B-Die you can gain 10 to 20% in gaming.

If your memory IC's like mine aren't great and the motherboard sets proper timings you're probably not going to be able to tune them much, but if you can its always worth it.
 
@humbug that's really informative, thanks.

I'll be pairing with 8 Pack Teamgroup kit, 16GB 2 sticks.

Or, I could pair with 32GB kit.

https://www.overclockers.co.uk/team...-3200mhz-dual-channel-kit-grey-my-0aj-tg.html

Motherboard is Tomahawk x570. I assume the 16GB kit would be better, but would it be "plug and play" or should I tweak for better performance?

I'm not looking for settings or detailed explanation BTW, just a general idea. :)

In AMD world, leaving CPU stock and memory XMP, you will mostly be in a good position.
Next simplest step is drop-in timings from DRAM caclulator. Already needs some time investment for trial and error and stability testing.

Going beyond that is purely for fun of the tweaking tinkering process.
 
16GB is fine, tho i have upgraded mine to 32GB, i think these days 16GB is the minimum, especially for a high end PC, which yours is.

As for the number of sticks, you gain a little performance out of the box with 4 sticks, but they are a little harder to tune, if you get 2 stick but they are Dual Rank its the same as having 4 stick tho they might be more like 2 sticks to tune, mine are Single Rank 2 sticks, not by choice it just how they came. I was i little gutted with them being 32GB i was hoping for Dual Rank.

Dual Rank vs Single Rank, Dual Rank both sides of the PCB have IC's on them and that helps with how data is channeld.

For tuning, if you set XMP and make a note of your timing, you can see them in Ryzen Master, compare that with what your timings should be, if its the same XMP its setting the correct timings.
If you want to tune them you need DramCalc https://www.techpowerup.com/download/ryzen-dram-calculator/ And that's a whole'nother set of instructions.

TBH if your timings are reasonable, IE not in the 21's for 3200Mhz i would just leave it as is, i'm quite happy now that my timings are not so lose.

If you want to guarantee your Motherboard sets the correct timings check the QVL list, but doing that limits you to what RAM you can get.
 
What sort of temperatures are people getting on the 5800X using air cooling?

I've heard it runs very hot?

I've got a 5600X running on a Noctua NH-U12 which stays around 30*C idle and around 55*C load.

If I change it to the 5800X what sort of temperatures can I expect with the Noctua?

Thanks
 
Did some more testing..... Clocks are from CB20 runs also I do have a Curve Op set on CPU (-30,-5,-5,-20,-30,-20-30,-20) @ 200mhz boost(5050mhz) Scalar is Auto for all runs

I'm was getting 81c max with the wraith prism at stock setting although now with the CPU tuned up it maxes out at around 70c.

76c max when heavy benching (AIDA64 stability testing) using manual PBO limits.
Cinebench testing max 73c
Gaming max temp ive seen is 69c
30c idle

Noctua U14-S
 
Compared to my 2700x its way faster. Bookmarks

I get about 35C idle and 77C with Cinebench at max, 60C in gaming with a Noctua NHD15s.
