The review
Page 1 of the review:
The VRMs are covered by decent-size heatsinks which did the job at stock, Precision Boost Overdrive (PBO) and while overclocking. Asus states a 12+2 VRM setup, but the board has a ‘true’ rating of 4x3 + 2, since the controller, the ASP 1106GGQW is a 6-phase unit in 4+2 mode. Power is fed to the VRMs through a required 8-pin EPS connector, plus an optional 4-pin which will provide more than enough power for the Ryzen 3 CPU lineup. I’m not sure how overclocking would go on the beefier chips, especially the 3950X, but the TUF board held up just fine with a 3700X.
Page 4 of the review:
Overclocking on this board yielded 4.224 GHz using 1.343V on the core. While the clock speed is a bit higher than what was achieved on the X570 Aorus Elite, this was due to spread spectrum and the floating BCLK as we used the same 42.25 multiplier. Anything above this voltage left us with temperatures above 90C, too hot for comfort. Regardless, anything above this multiplier at this voltage caused an error in stress testing.

G.SKILL F4 DDR4 3600 C14 2x16GB

32GB DIMM DDR4 clocked @ 3600 MHz
How could he get 3600mhz without XMP enabled?
Ryzen 5000 ram guide
And he has the fastest cas 14 memory too.
Should be at the 1:1:1 fclock ratio with 3600mhz and he has the exact same gskill kit for it?
Model F4-3600C14D-32GTZN gskill /what userbenchmark says it is
What the actual A ?
On
gskill product page there is also F4-3600C14D-32GTZN
A but I don't see 32GTZN on it any more. Dunno what it means though.
So if everything's supposed to be optimal, yet the memory is severely underperforming according to userbenchmark it sounds like as soon as it hits that 3600mhz optimum clock with infinity fabric, it's actually... not?
Drives me barmy that the author of the 5000 series ram guide listed the exact part number of the c15 4000 memory but not the exact part number of the c14 3600 memory. There's an N and an NA. dunno what it does. Later model? Have to ask gskill. If it's the exact same thing with the exact same timings why's it got an A?
When you say similar - are they using the 4000mhz c15 memory overclock?
DDR4-3200 should unquestionably be the starting point for Ryzen 5000. We recorded a 5.8% performance difference between DDR4-2133 and DDR4-3200, the native frequency supported on Zen 3. Our test results confirmed that DDR4-3600 is still the sweet spot for this generation, though. It delivered 7.2% more performance than DDR4-2133. Compared to DDR4-3200, however, DDR4-3600 was only 1.3% faster.
Unsurprisingly, DDR4-4000 is the ultimate goal if your processor and budget allow for it. The performance gap between DDR4-2133 and DDR4-4000 stretched as high as 7.7%.
Compared to DDR4-3200 and DDR4-3600, DDR4-4000 provided small uplifts in the range of 1.8% and 0.5%, respectively.
'In a gaming environment, DDR4-4000 and DDR4-3600 offered 4.2% and 5.6% better frame rates, respectively, than DDR4-2133. '
As always, memory frequency only impacts specific titles where the processor does all the heavy lifting and the game engine responds well to improved memory performance. For example, DDR4-4000 netted up to 6.1% better frame rates than DDR4-2133 in
Shadow of the Tomb Raider and up to 19.7% in
Far Cry New Dawn.
- Memory ranks often don't contribute to better gaming performance on Ryzen 5000, but memory frequency does in an environment where your graphics card isn't the bottleneck and the title taxes the processor heavily.
- Even on Zen 3, four memory ranks are still the ideal configuration for getting the best overall performance out of your Ryzen 5000 processor, particularly in applications. With today's capacity, this basically translates to having at least 32GB of memory in your system, whether it be two dual-rank or four single-rank memory modules. Most of the time, the first option is always easier on the pocket.
So you're chasing a few % - Maybe they have 4x8gb single rank instead of 2x16gb or maybe they have a different mobo , or both or maybe even a 4000mhz overclock: Is the Cyberpunk game engine one that responds to a higher memory frequency? Who would know that?
Oh more barmy:

G.SKILL F4-3600C14D-16GTZN 2x 8GB SS Samsung 14-15-15-35 1.35 Ryzen™ 5000-Series CPU 3600
The 8gb modules are single sided so the 16gb modules must be Dual rank or Double Sided (but not on the qvl exactly 100% precisely) and the
product specification page doesn't say if they are in fact, single sided or double sided dimms: Like 8x2 samsung or if they used like larger hynix chips on the actual 16gb dimm so they would be single sided. Have to ask Gskill.
G.SKILL F4-3600C16Q-64GTZNC 4x 16GB DS SK Hynix Well the 64gb kit 16x 4 hynix dimms are cas 16 and double sided.
Could also be 'silicon lottery' between sets of dimms basically you're looking for perfection where all the odd % differences are stacked in your favor.
Well it's totally weird that the Precise Exact information on that simply Isn't There. Well maybe all that means is, science is unable to attain perfection.
