After seeing all the benchmarks around the web, i can only conclude that Ryzen platform is poorly optimized. It's sad to see this as a result of Intel dominating the market for so many years and most software are optimized for Intel architecture. Nevertheless, this is a huge leap from AMD and this will definitely benefit all consumers.

G.skill has DDR4 3200 sticks that are verified to run at 3200 4x16GB configuration. Nice!

Among the 3 Ryzen models, I can't see the point of buying the 1800x. 1700 can overclock just as high as 1800x (maybe just 100mhz lower). Same 8c 16t and same amount of cache. Perhaps AMD traditionally likes to give 'free' performance to end users, like some Phenom II that can be unlocked to gain extra cores.

These RAM can run at 3600 on Ryzen.

Wow, which motherboard is that?

Hi everyone,
I just bought a new system as my old motherboard suddenly died. I got:
- Ryzen 3700x
- Asus ROG x570 Strix E
- Kingston HyperX Predator 32GB 3200MHz CL16 (HX432C16PB3AK2/32)

I'm still waiting for the RAM kit to arrive so I'm wondering if it can easily clocked to 3600MHz. It should be Hynix CJR. I couldn't find Micron E Die in the market now. Samsung b-die are just too expensive.

For the past two days i've been setting up my new 3700x with x570 ROG Strix-E motherboard. I've noticed a strange behavior where if I overclock my RAM speed from 3200MHz to 3600MHz or 3733MHz without touching any other settings (besides increasing the RAM voltage slightly to 1.37V), the processor boost clock will not reach 4.4GHz as advertised (max 4.35GHz only). But if I run my RAM at XMP 3200MHz, the processor will boost normally to 4.4GHz on single threaded workload. Going back to BIOS default and increase the RAM speed again still observe the same boost behavior. How weird.

I'm using the latest April BIOS version and so far I have not overclock the processor. The CPU temperature also never go above 65C on single threaded workload and around 80C on all core.

After playing around with the CPU and countless reboots, I concluded:
- 3700x will not boost to 4.4GHz in single threaded workload if cpu temperature (Tdie) is more than 60C
- All core boost also temperature dependent and usually can achieve 3950-3975MHz if temp below 70C. If enable PBO, can go up to 4100MHz (I have yet tried more aggressive PBO).
- When PBO enabled, all core load voltage is about 1.30V (CPU voltage set to auto in BIOS).
- Overclocking to 4.4GHz (all cores) @ 1.30V and LLC Level 5 is stable enough to run benchmarks. But unstable after 10min of OCCT. Socket power draw can go up to 130W
- Overclocking to 4.3GHz (all cores) @ 1.25V and LLC level 4 is rock stable. Max temp was around 76C with OCCT stress test. Looks like i have a pretty good piece of silicone.

Coming from Phenom II era, this new CPU is very interesting. Performance varies with room temperature and can be shown on benchmarks.
Very interesting behavior.
