Corsair Vengeance RGB PRO White 16GB 3600CL18 [ CMW16GX4M2C3600C18W ] | 5600x

[drex96]

Hello everyone,

I've just built a new PC featuring the 5600x on a MSI MAG B550M BAZOOKA and with a dual channel kit of Corsair Vengeance RGB PRO White 16GB 3600CL18 [CMW16GX4M2C3600C18W] (Rank 1,Micron E-Die).

First problem encountered was that posting with FCLK higher than 1833 is basically impossible even with ram at 2133. I understand that it's related to the early version of bios, im currently on the latest (7C95vA51(Beta version)). So i'm stuck with RAM at 3666 and FCLK at 1833 for now at least.

I'm looking for an opinion about my timings and how i can improve. They are manually tuned (since the DRAM Calculator ones were screaming errors as soon as i open any memory test) and it's my first time doing this in depth.





DRAM = 1.4v
SOC = 1.1v
VDDP = 0.95v
VDDG CCD = 1.05v
VDDG IOD = 1.05v

For testing i used TM5 with anta777's Extreme1 profile. It completed the 3 cycles in 1 hour and 14mins with 1 error on Test 2.

Thank you all in advance for your help!

Your results are good and you won't make anything much better. All new ICs are from various bins, even under the same product number, so you can't really use someone else's settings and count it will work. There are too many variables and some timings depend on the motherboard. In general, ~3600 CL16-19-x-x is already a good setting for Micron E.
You may try a 1:2 ratio and something like 4600-4800 18-22-x-x or 18-24-x-x. Ryzen 5000 has lower latency and sometimes these settings work better than 1:1 at ~3600. I'm just not sure if your motherboard will handle it.
I don't remember exactly how it was for Micron E as I play with B-dies recently but some of these timings on the list look too tight. For example, tFAW 16 usually doesn't work. I would back to auto sub-timings, compare them with what you have on the screenshot, and drop them in smaller steps.

New BIOS should arrive next month. I actually have some issues with MSI X570 Unify. It works and overclocks well but at some settings, it's acting weird and with higher capacity modules it has problems running at DDR4-3600+.
In general, it looks like the higher CPU you buy, the better IMC you can get. It's not a rule but the only DDR4-3866+ 1:1 results that I saw, were on 5900X/5950X and 8GB memory sticks. My 5900X can't really boot above DDR4-3800 1:1 but exactly the same was with 5600X and 5800X that I had before.
