you'd be surprised to see how well their cool&quiet, cstates, etc. working once you slot a renoir or probably cezanne into your board.
but since those are plagued by low cache this is also no solution (apart from the availability)

yeah I think so, the io die seems to be the main factor. the monolithic renoir really not too bad. can build a massively energy efficient system with that.
I've seen ppl having idle system! draw of sub 10W with a pico psu and renoir.

Giga n MSI already leaked their new X570S chipset boards, too.
Probably be coming same time with the B2 stepping Vermeer's.

If I didn't get things wrong you're mixing up things.

If cores on different CCD's communicate with each other this has to go through the IO die and therefore through the IF. What speed (bandwidth) your ram is running should be irrelevant at this point, as it is not part of this communication process as inter-core latencies are within the L3 caches.

Bit of a weird one though. No pcie4.0 coming from mobile, half the cache... doesn't really make much sense with that gpu

running at 8GT/s so that's 3.0 is it not?

sai86
well gaming and downloading games I've never even been remotely close to 90C when I tested the 5900x... are you sure your pump is working properly?
or if you have a proper sensor... what's your flowrate?

update the bios as suggested, then enter your own power limits PPT, TDC, EDC (142, 105, 140) as your board increased them and then report back.

That's the AMD default sai86. It's thanks to reviewers 'comparing boards with the same cpu for benchmarks' without pointing out what happens that manufacturers and especially marketing divisions don't bother sticking to AMD default limits anymore with their out of the box bios configurations.

The 5800,5900, and 5950x have 142,95,140. The 5600x has 76,60,88 as limits.

Another way they love to cheat is with telemetry (hwinfo64 shows this as power reporting deviation)
You could fix these as well if your board has the options but that's not really necessary as of now.

regarding power reporting deviation you are correct, it is only valid on full loads. eventhough cb20 cycles it's pretty easy to test there.

just run multicore n see what the value goes though.
most likely its overreporting. in the case that u'd want to fix that u'd have to go yo your bios (ai tweaker), set CPU Core Current Telemetry to Manual and set a negative offset and try values until you reach something close to 100% in cb20.

but then again, this is not the culprit to your temp issues.

lol am I the only guy spreading his paste in a very thin layer manually before slapping the block on?! or do you all have extremely convex or concave heatspreaders?

to thankyou what board is exactly being used? do you have to option to OC your ram in the BIOS and which options are available?
This is where you should be able to extract most performance.
Other than this you could check if curve overclocking is available as well, this would be a little interesting as well.

Useful info right there. Pretty sad that you can't utilize the strong IF on the 5700G
So for those who are out for an Cezanne they rather wait till Retail stocks arrives in just about less than 2 months time.

Thanks! Try using the Ram Turbo n see what changes.
https://zentimings.protonrom.com/ use this to check.

So worthwhile upgrades would be 1) a cheap B550 board and 2) a better cooler.
Potentially a 3) new RAM Kit for some who need a higher capacity/speed(depending on the IC on your current kit)
Still fine value right now with that 3070 (with a nice 12 pin connector btw)

I've got a B550M A-PRO here which I got with a bundle, which I might use for a Cezanne that will probably be running somewhere between 35-65W PPT and will be cooled by a Fuma 2.
Can't wait to try that then. Let's see how high I can push RAM on that shitty board ... endgame on RL already and bored.

Will do, I hope early August AMD MY will release them in time. Will be interesting to see how well cheap boards work with it n not a 1k myr board like the B550i Strix that I used last time (great board btw).
Latency should be (well?) below 50ns. But I doubt this will absorb the cache disadvantage.

they just seem to be clocking ~150-250MHz lower in average. be it single core or multi core. even with ramped up power targets and curve oc they settle in at a lower point as neither is as fruitful as expected.

an optimized 5700g slightly outperforms a stock 5800x in eco mode in cb r20.
in sc it roughly matches a stock 5600x after curve OC.

Scroll down to my quick test for the 5700G (and have a good look at what owihk keeps posting, his posts really are valuable continuous quality content).

I think it has it's place in the line up and with the $USD pricing they might replace the 3700X and 3600 at similar prices. Gaming performance with discrete GPU is an issue but other than that there are strong sides.

Zen 3 is fine without, still some benefits (power draw idle) with certain power plans but the windows default one work much better already.

This
if it happens during high system stress. An aging PSU can get overwhelmed by transients pretty easily.

Can't really give any valuable insight for air cooling the 5800x3d.. however I noticed that mine running pretty cool with my custom loop after using the PBO2 tuner desktop app.

I suppose this will be quite useful for those air cooling it as well.

And given that for the 5800x3d extensive RAM OC is hardly worth the time, (if performance is what you're having in mind) it's well worth to spend that time elsewhere and use it running corecycler to figure out stable settings.

Here's a decent guide on how to do it
