***The Official 5600X \5800X owners thread***

Just received a Noctua NH-D15 Chromax to replace my Scythe Mugen 5 Rev B. Maybe it's not going to be a huge difference but a few degrees cooler at load seems to really matter with Zen3. I hope I can squeeze it into my Be Quiet! 500DX... the RAM clearance of my Gskill Neo Z means I either have to use just one fan or raise the second fan up, which may not be possible in my case. Lets see. :D

I may wait to install it until my 5900x finally arrives. I have decided to keep my 5900x pre-order (£430) as I am not fully happy with my 5800x, it's not a great piece of silicone and I know I will regret not having the CPU I really wanted to last me the next few years. With 5800x stock now running out I should be able to sell it for roughly what I paid for it.

Mind taking before and after benchmarks 5800X vs 5900X (whatever cooling)? Especially gaming and maybe single/low thread stuff.

Obviously multithread will be a win for 5900X. But rest should be pretty much equal. With CPUs curve optimized 5800X may be pulling ahead.

Im not so interested in running many benchmarks other than Cinebench, there are many reviews online comparing all Zen3 CPU's that we can all read so there is no new data I can pull up, other than what is specific to my config, that hasn't already been tested and proven elsewhere.

I want 12 cores for the additional multi-threading chops and I ideally want a cooler and better clocking piece of silicone as my 5800x seems to be a poor performer in this regard. For gaming the only benefit will be any improvements in sustained clock speeds or overclock.

Is that poor performance in it's boosting ability (does it reach it advertised max boost?) or in a benchmark score?

Obviously it reaches stock advertised clocks, otherwise I would have said so. However in addition to running really hot it's a crappy piece of silicone with a low sustained boost speed (there are two particularly weak cores) and has been very unstable when tweaking negative offset values. I'm not satisfied with it.

What is your Boost speed?

If I leave it at stock settings then Cinebench tops out at a sustained boost rate of 4350mhz, whereas I can manually clock it to an all core OC of 4525mhz at 1.26v and it runs fine all day with way lower idle and max temps. Setting negative offsets to improve PBO results in instability and at the moment I haven't got the time or patience to spend painstakingly testing each core individually.

The crazy voltage spikes with PB/PBO when everything is at stock settings and not much is goiong on that even needs any significant processing power are really annoying and lead to unnecessarily high temps vs setting a manual OC.

Still, I got a crummy CPU and I will be happy to swap it out for a 5900x.

Ouch, should be 4.65Ghz or 4.7 if its under 80c. looks like you lost the silicon lottery with that one, sorry man :(
 
Holy **** guys... I just had my lunch break and decided to install the Noctua NH-D15 Chromax and my temps and boost speeds are wayyyy better!

CASE: Be Quiet! 500DX
CASE FANS: + 3x Silent Wings High Speed @ 50% (2 front 1 rear)

-------------------------------

Mugen 5 Rev B w. Noctua NF-A12 @ 75% (OLD)

Full auto PBO settings:
  • Stock idle - 55c
  • Stock Load - 90c
  • Stock boost consistent mhz - 4350mhz
  • Stock vcore avg - 1.3
Manual fixed OC:
  • 4525 @ 1.26v idle - 50
  • 4525 @ 1.26v load - 87
-------------------------------

Noctua NH-D15 w. 1x Noctua AF-A15 @ 75% (NEW)

Full auto PBO settings:
  • Stock idle - 45c (-10c)
  • Stock Load - 88c (-3c at 150mhz higher boost and 0.8v higher voltage)
  • Stock boost consistent mhz - 4500mhz - (+150mhz)
  • Stock vcore avg - 1.38 (+0.8v)
Manual fixed OC:
  • 4525 @ 1.26v idle - 45 (-5c)
  • 4525 @ 1.26v load - 78 (-9c)

-------------------------------

Wow, I expected better temps but not THAT much... and clearly PBO likes what it sees as can be seen from the higher consistent boost clocks and voltage when running Cinebench R23. I have no reason to think my Scythe Mugen wasn't seated correctly, thermal compound also seemed ok.

Also that is using only one of the supplied fans at 75% speed... I didn't seem to have the RAM clearance for the second fan but I can likely add a 120mm instead. For the meantime, the front case fan draws air in directly on to the heatsink where the second fan would otherwise be.

That, gentlemen, is a direct and real-world example of AMD PBO responding to superior cooling under the same conditions. :)

I still have a crummy CPU sample though. :p
 
Very nice. Given the now very small difference between the PBO and fixed OC, I'd be tempted to let PBO do it's things so you can enjoy the higher boost clocks for stuff that will benefit, your idle temps are now identical after all, and whilst the load is higher, if its clocking up further that seems fair!
Your manual OC is now essentially moderately limiting performance in low core/thread usage whilst offering only a temperature benefit at all core! haha :)
 
Yup, the room they have the more they will boost, they just keep going until they hit TJMax or can't physically go any higher.

Try this, put PBO back to auto and set negative curve optimiser 15. see if it boosts higher. it might.

Agree 100% guys! I will try a negative offset to see if it's stable.

I re-ran the CTR2.0 test too... I got ebtter results but it does warn me of 3.2% vdroop and recommends I add a positive voltage offset.

Well humbug, I added a -15 offset as you kindly suggested and it ran Cinebench R23 with these results:

Multi score: 15335
A sustained boost of between 4550 and 4600mhz
Load temp max 90c
Vcore average 1.27

Single score: 1589
A sustained boost of 4850mhz
Load temp max 66c
Vcore average 1.336

Wow, I honestly didn't think I would see such a significant improvement switching to the Noctua D15 from the Scythe Mugen 5 Rev B. I should have just bought it in the first place and not messed around with any "good value" options. Sigh. :)
 
Well guys, I was suffering serious instabilities in my rig, with constant crashes etc and it turns out I had corrupted my OS install and recovery partition, likely not helped by OC-related instabilities and/or reboots during windows updates and the use of various tools like Ryzen Master and CTR 2.0 and of course the scummy Dragon Center from MSI. All of these tools hook deep into the low level workings of the system and the way I was using them probably wasn't healthy. Anyway, after a lot of unsuccessful troubleshooting to restore the corrupted partition, a re-install of Windows was the only way to redemption.

However, after this Windows reinstall my PC is working fabulously. I have not reinstalled Dragon Center, Ryzen Master or CTR 2.0 and am determined to do everything via the BIOS instead. As a result, my PC is now damn near silent due to the superior BIOS fan curve control where both my CPU and system fans are now tied to the CPU temps (for some reason the BIOS provides superior options to Dragon Center in this regard) and the fans only kick in gradually from 50c to 75c and never at full speed.

I also changed PBO to 95w eco mode in BIOS and still get a cinebench score of 1605 / 15250 and my temps under max load do not go above 79.5c which is impressive. Amazing what a positive difference the Noctua NH-D15 has made vs the Scythe Mugen 5 Rev B.

My system is now so fast, quiet and stable that I am reluctant to mess around further with it. :D
