[SOLVED] Overclock memory on ASUS Prime B350-Plus & Ryzen 5 3600?

[LrsLex]

So I've read in several posts that the hassle of overclocking RAM might just be worth it. I've also been led to believe that there's relatively little returns in Overclocking the 3600. To begin with, here's what I've got:

Ryzen 5 3600 @ stock
ASUS Prime B350-Plus
2x 8 GB Corsair Vengeance LPX (Hynix) CMK16GX4M2B3000C15 @ 2933 MHz
Fractal Design Edison 650 W

CPU-Z

I'm thinking with this board the best I could hope for is a 3200 MHz RAM speed and even that's depending on my luck with the sticks. What I'm hoping for is maybe a bit of a boost for FPS and a snappier desktop performance. I also read the CPU may be easier to OC with a lower voltage if the RAM timings are optimal, no idea if this is true.

The question is, is it worth it for the potential 200 MHz boost? I tried to trim the timings on the same memory back when I had a 1600X. Did the Thaiphoon & Ryzen DRAM Calculator thing by instructions, painstakingly inputting every figure in the BIOS only to not post and having to reset the CMOS. So I left it then because I had no idea why it didn't work nor how to continue. I'd also be much more inclined to overclock if it didn't involve repetitive CMOS resetting and removing the battery. Thankfully not every fail requires that. 😀

Thx for the input!

Problem with 300 series chipset MBs is memory topology, only RAM with Samsung b-die chips was able to do any significant frequency boost above 2933MHz.
OC-ing to 3200MHz invariably gets higher memory latency negating much of a gain in total performance.
Instead of overclock see if you can get lower Cl. When I had a x370 MB I manage to lower Cl to Cl12 on my Kingston 3200 RAM, with Hynix M-die which gave me better overall performance than 3200MHz CL 15.

Okay... Any tips how to go about this? I've checked a couple of guides on tightening the timings and I frankly don't understand it at all. 😏
The Ryzen DRAM Calculator method tweaks just about every value in BIOS and I couldn't get that to work. Some guides talk about just changing a few values of those in the CPU-Z screenshot I posted. Like should I just input values according to this chart, leave the rest of it in BIOS as is and see how low I can go?

Frequency	CAS	RCD	RP	RAS	RC	RRDS	RRDL	CCDL	FAW
1067 MHz	16	15	15	36	50	4	6	6	23
1067 MHz	15	15	15	36	50	4	6	6	23
933 MHz	14	13	14	31	44	4	5	5	20

800 MHz	12	11	12	27	38	3	5	5	17
800 MHz	11	11	12	27	38	3	5	5	17
667 MHz	10	9	10	22	31	3	4	4	14
667 MHz	9	9	10	22	31	3	4	4	14

For example, could the values for 2133 MHz on the top line work for 2933? Like I said, I'm completely lost with this. 😆

That is JEDEC table, need to look for XMP table. Thaiphoon burner http://www.softnology.biz/files.html can tell you more about your RAM and XMP profile of which highest should show about 1499MHz.

And here's the calculator's values that I got:

So, Zen 2 since it's the 3600...
I set type to Hynix AFR, since AFR is in the component serial number:

H5AN8G8NAFR-TFC

Now, I left the DRAM PCB revision to manual as I don't know what my memory revision is. It says downbin in the Thaiphoon report, but I don't know if that means bad bin. Anyway, manual only lets you calculate the safe option. It says here that you can see which PCB the memory is, but it all looks the same to me without x-ray vision to see through the cover material. 🤔

Guides to the calculator tell you to set the frequency to the RAM's namesake, so here to 3000 MHz, but importing the Thaiphoon data sets it to my current 2933. When I originally clocked the RAM to 3000 (from 2133, when the Ryzen 1 support got better) by the Asus DOCP, it automatically set it to 2933 and I just left it there since there really isn't any difference in performance. I guess it doesn't matter here either, except to put the right values in since some of them change between 3000 and 2933? Or maybe I should tweak the timings here at 2933 since it's proven to be stable at that speed?

How's that sound? Thanks!🤓

Tinkered around a bit but couldn't get anything manual to stick. Tried a couple of settings from the RDC, once even got to Windows but then BSOD'd. Minor progress though: the D.O.C.P Standard got the RAM speed from the 2933 up to 2994 MHz and even trimmed the timings a little from before.

edit.

Just remembered: my RAM sticks are in slots A1 and B1, when the MB manual recommends A2 and B2 slots. When I built the machine, it initially recognised only 8 gigs of RAM. Moved them to 1 slots and it worked. Might the slot selection affect OCing success?
