Hi Guys,

I have a workstation with a Threadripper 5995wx CPU.
I have 128 GB RAM (32gb x 4) running at 3200 MHZ.
I did the Corona Benchmark in the morning (benchmark 1.3 and the new benchmark) and I got some good scores: first one 17 seconds, and the new benchmark 22 843 900 rays/s.
I've got a Cooler Master ML360 TR4, and the temps are 65 under full load.

I've installed AMD Chipset drivers, and now I get really bad scores (33 seconds, and 15 897 916 rays/s)
I have uninstalled all the AMD drivers, even restore the windows (to the point of having nothing, just right after I've installed the windows), and still getting these bad scores.

Even my other 3990X gets ~ 21 000 000 rays/sec.

I've attached the screenshots, on the left are the first results, and on the right the one that i have now.

I don't know what I am missing but maybe you have some advice.

I mean...you can just run the benchmark 20 times and the result for 3990X will be anywhere from 17 to 20 seconds. It just isn't a good benchmark at all, outside of all the randomness introduced by actual voltage, current, room temperature, OS overhead...

I can't believe people get hang-up on something like this :- D.

You were right. I moved my PC in another room, and I left my front case open without any dust filter  (Define R6 Case) and voila, the CPU temperature dropped from 80 to 65 degrees on heavy load, also the CPU speed increased from 3.2 to 3.5.

I have no interest in benchmarks. With XMP enabled @ 3200 MHZ, my CPU it's stuck @ 2.9 GHz in Corona. At 2666 MHz my CPU it's stuck @ 3.3 GHz, so maybe for 5K does matter. My default RAM works @ 2133 MHz but I didn't tried that yet, so I've got to do some tests.

So this is weird...when I enable XMP on my 3990x build (or actually d.o.c.p. in this case, first I've heard of that acronym) and bump my RAM from 2666 to 3200mhz my benchmark rate actually worsens.  I go from 17 seconds to 18 seconds, every single time.  I wonder if the system is pushing CPU clocks down because memory clocks are higher?  Temps don't seem to be a problem, I'm upper 50's lower 60's for CPU.

Not a huge deal, but odd!  Currently stepped back from the faster ram speeds since I can't see any benefit?

I have the same issue, did you find any solution ?

@lolec - what is your RAM speed and infinity fabric clock? (IF clock in BIOS)

Ideally, they should be "coupled" - e.g. in my case 3900x with 2 sticks of RAM running in dual mode at 3600 MHz and IF clock set to the default of 1800 MHz. 

Oh and you can also check enabling different power plans in Windows. Download and install Ryzen Master, and then activate the AMD Ryzen High Performance plan.

In power plans I can see just the AMD Ryzen Balanced. How can I activate the High Performance one?
Thanks.

Hi Guys,

I have a question. Yesterday I ordered my 3990x build, but as a cooling solution i've added a be quiet! Dark Rock Pro 4 TR4. I've watched some testing on a 3970x and it performed pretty close to Noctua, but i couldn't find any testing on a 3990x. I didn't chose Noctua because of looks, i really hate that shitty colors. Later i checked on be quiet! website and on specs are mentioning that DRP it recommended on a max 32 core CPU. Should I worry about this ? Does this influence the performance of CPU?

You can see that on my photo one page back as well with what are not even low-profile memory modules. Also..with 2x A15 fans. But I tested that configuration one time before already and the result was the same this time, there is no thermal improvement (after all just 10 cm to the left is Case Exhaust fan again, so it's basically 3x vs 2x. The heatsink is too narrow and it creates very annoying resonating turbulence. Noctua A12x25 (120mm) fan would probably give better result for this situation and with much nicer sound profile.
(It's incredible how much more advanced the A12x25 is compared to A14/A15. Even at same noise level...the noise is super pleasant, low-pitched humming car engine, not high pitched jet engine.)

Is the Great Wall M1200 PSU something you already have? If not, I would suggest changing to something more reputable like Seasonic Prime series (or Corsair AXi which is also made by Seasonic except for 1600W top model).
Any reputable brand (BeQuiet,..) or OEM (SuperFlower) works but your choice is bit obscure. High-end PSU is paramount to stability of PC, but esp. for 4000 euro CPU.

Any reason for going with 5400 RPM HDDs ? Are these just for back-up? Because otherwise they're far too slow,..even for backup.

Then I will add an extra A12.
I choose that PSU because I need to buy everything just from one store and the 1200w Corsair its double the price (around 500 euro). They have Corsair Professional Series Platinum HX1000i  but I'm not sure 1000w is enough because i'm planning to add an extra RTX 2080.
HDD are fore backups, but you are right, it's better to switch to 7200.
Also i'm not sure about 512gb A-DATA SSD- PCI, M.2, PCI Express 3.0 , even it has a lot of good reviews.

Thanks for advice!

Hi guys,

I want to buy next week a 3990x workstation.
What do you thing about this config:

AMD Ryzen Threadripper 3990X 2.9GHz box
Noctua NH-U14S TR4-SP3
GIGABYTE AORUS TRX40 MASTER
GIGABYTE GeForce RTX 2080 Ti GAMING OC 11GB GDDR6 352-bit
HyperX Predator Black 16GB DDR4 3200MHz CL16 1.35v   x 8 (128 GB)
SSD ADATA SX8200 PRO 512GB PCI Express 3.0 x4 M.2 2280
Seagate BarraCuda 4TB SATA-III 5400RPM 256MB x2
Inter-Tech GW-M1200, 80+ Gold, 1250W
Fractal Design Define 7 XL Black Solid

Also i want to add another Noctua NF-A15 PWM fan for CPU , but from my experience with another 3970X configuration, this will cover 2 slots of RAM, so you will have just 6. This happned with AORUS TRX40 PRO WIFI. I dont know if TRX40 MASTER its bigger.
