What exactly is 3600MHz with terrible timing?

Nothing wrong with Hynix die either, don't be too obsessed with Samsung B-Die.

Air cooling? Many people have it in the 50s and they live in much cooler countries than msia. If you're getting 45c, that's not bad at all and is rather normal.

Alright been using the 3900x for a week now, quite a happy camper here. Tuning memory is fun, haven't had this much focus on memory since the DDR2 days - quite a nostalgic feeling.

Stuck with AGESA 1003ABBA BIOS though due to some issues with PBO on 1004B. How are you guys doing with AGESA 1004B?

Seems to me that manual OC is better than PBO at the moment for most apps - as long as your silicon quality is decent.

I got 4.4ghz all cores @1.325v vs PBO doing 4.55 for 2 cores and all others being 4.1 @ voltages spiking to 1.48v. The manual OC is much, much cooler under max load too (70c vs 79c, on a Noctua D15s). PBO gets like a 100 points more over manual OC in cinebench R20 and extra ~3fps for 99th avg percentile in AC Odyssey.

Are you on 1usmus power plan?

Vcore drops/increase under load can be optimized using LLC setting in your bios. Check it.

Turns out 4.4ghz @ 1.325v isn't 100% stable for me. Was encoding a video on handbrake and an error came up, eventhough it's minor.

Turned it down to 4.25ghz @ 1.30v - brought down load temps to 65c and losing only 2% overall perf. Not a bad trade off I guess.

EDIT*
1.325v isn't a magic number and it's NOT SAFE for Zen 2?

Very common issue it seems. Razer synapse 3 also consumes high CPU power and simply boosts your CPU clocks to the highest for no reason.

What monitoring software do you guys use to check the temperature without it going boost all the time? I’m already modding the fan curve like what you said too.

To those using x570 Aorus Master, do you guys have the issue where the graphic card is touching the chipset heatsink?

I can't see any sign that the heatsink is not fixed properly, it looks fine to me.
But it is definitely higher than the height of the PCIE slot towards the top portion, and since only the top PCIE slot is 16x, we dont really have any option to use lower slots.

So far the graphic card seems working fine for me though. I think it slots in just enough to make sufficient contact, but I can't get the PCIE clip to click

I mean the heatsink for the x570 chipset, the one that have a fan inside it.

I might need your advice here. Ok the thing is, I have an R7 3700X . X570 Auros Master.
RAM I have 2 kits:
1. G.Skill Trident Z RGB F4-3600C18D-16GTZRX
2. G.Skill Trident Z Neo F4-3600C18D-16GTZN

I bought these 2 slightly different kit because of stock availability issues.

I can run 3800Mhz 18-22-22-42-64 1T with a ridiculous TRFC at 666 ( shown in hwinfo64) but only with 2 sticks of Trident Z Neo. FCLK 1900Mhz is stable under Asus Realbench for 4 hours. If I run 4 sticks of RAM, I cannot achieve stability.
Currently VDIMM at 1.38V, VSOC 1.1V , CPU use PBO only.

My main issue is I cannot tighten the timings using 1usmus's Ryzen DRAM calculator as guide (even safe preset, wanna go down at least CL16 ) or increase VDIMM to 1.45V like that. Cannot POST , mobo throws me a C3 code and I have to use the BIOS reset button to recover. From 4 sticks I reduce to 2 stick of RAM, same thing.

Using Thaiphoon burner, I can confirm all 4 sticks of RAM I have are Samsung B dies. Do they really that suck for lowly binned ones ?
