Adata Value RAM (3200MHz OC to 3800MHz)

Hey folks, would like to share my experience on my latest build using Adata 8GB Value RAM. The OC performance seems quite ok.

Recently I've decided to build a production machine for my company, and the component selections are as follow:

CPU: Ryzen 5 3600
RAM: Adata DDR4 8GB 3200MHz x 2 sticks (found this on Shopee, just need to pay abit more compared to normal 2,666MHz & cheaper than other gaming RAM)
SSD: Adata XPG SX8200 Pro 512GB
Mobo: B450m Steel Legend
GPU: Palit GTX 1070 Ti
PSU: Super Flower Leadex II Gold 650W

Actual installation:
Have to install the RAM at A2 & B2 slot for best performance.

Upon booting up, everything seems normal. The initial RAM timing is quite underwhelming.

I read that Ryzen 3rd gen loves high speed RAM. So first thing to do is, reboot and go into bios, increase the RAM speed to DDR4-3600, and increase FCLK to 1,800 to match the infinity fabric clock to memory clock at 1:1. RAM timing and voltage were not touched. Boot up as normal and everything passed.

Next, reboot and increase the RAM speed to DDR4-3800, increase to 1.3V. Success!

Then, reboot and increase the RAM speed to DDR4-4000, increase to 1.35V but blue screen when booting. Increase voltage somemore to 1.4V (max by this mobo) but also failed. The system will not boot in whenever I dialed in 1.35V/1.4V. May be limitation of this RAM or the mobo itself.

Noticed voltage turns red whenver I dialed in 1.35V and above.

Simply won't go higher than 1.4V.

So, I guess this RAM can be settled at DDR4-3800. And I tighten the RAM timing to 20-22-22-46 which booted up as normal and passed tests.

Final timing is 20-22-22-42 at 3,800MHz

For 3,600MHz at 1.3V, best timing is 18-19-19-40.

After all experiments, I've decided to settle at 1:1 FCLK & mem clock at 3800MHz. Loosen the timing abit at CL20.

Next will be upgrading the stock cooler. Not really comfortable with the CPU idling at 55C
CPU temp will go up to 95C which is the thermal limit whenever I stress test the CPU. Probably with a 240mm AIO water cooler.
