rent0n I know this is a X370/X470/X570 thread, but I didn't find a dedicated one for the B Series chipsets, so I'm going to ask here: has anyone had any luck pushing Samsung B-Dies to 3800MHz CL12 on a B450 board? I have a F4-3600C16D-16GVK Kit, which was bought last month. According to Thaiphoon each module has an A1 10-layer PCB, but I'm pretty sure it's an A2 layout, so that reading should be wrong. Anyways, I am running a Ryzen 5 3600, which can go as high as 4.6-4.7GHz on air for benchmarking and so far the memory sticks have been running at 3800MHz (1900MHz FCLK) 14-14-14-28-1T-42-260, GDM off. I haven't had any luck booting at CL12 even with GDM enabled, so I'm thinking either the bin of the kit is not that good, or the mainboard is just bad at memory overclocking, it's only a MSI B450 Tomahawk MAX. If anyone has any experience or suggestions, I would be glad to hear them. Cheers.


P.S.: I am about to try the latest BIOS update with the AGESA 1.0.0.6 tonight, gonna report if that makes any difference.

Did you get to do some testing ?

EDITOH your talking about Ram but I forgot to add a stupid Cinebench20 test with my new DDR4 3600Mhz Ram

My 3800X is getting Jealous of the New 3800XT but it is still fighting strong with a little BCLK

The rant



I understand exactly where you are coming from, lol

So some new information and thanks for relaying your experiences.

I am having to retest again as settings that were "known" to work at different fclk are no longer "valid" with this new BIOS for my X370.

Managed to determine that VDDP voltage now needs to be alot lower than previous agesa version otherwise TM5 errors with codes that I have rarely seen and with no specific "pattern".

Before 3800/1900 required [email protected], [email protected] and [email protected]

Dropping VDDP to 0.805 - 0.850 (still testing) stops almost all of those weird and wonderous error codes in TM5.

Still need to play with vSOC as this probably needs further tweaking along with VDDG CCD/IOD.

And back to your rant,

Currently running/testing [email protected], this gives me 3800/1900, previous fully tested stable BCLK was 106.725 which gave me 3766/1888.

Attempting to balance alot of things with TM5 running all core loads between 4490-4520 mhz while finding the right balance of voltages and LLC to keep everything nice and stable while at the same time maintaining a clean 3800/1900 mclk/fclk combo while at the same time using [email protected]



Performance is amazing for this 3600 with the combination described above.

Oh and one small cavet, I have to reduce my PCIe to Gen2 to be able to get to OS with such high BCLK otherwise the VGA goes all wonky



I actually get better 3D performance with my hardware using Gen2 rathar than Gen3 even when not using BCLK, so really no loss.

Have yet to experience any anomolies with my nVme/SATA/USB device so far

I am no longer TM5 stable when testing 1900 mhz fclk.

Previous BIOS was rock stable at 1900 mhz.

Mokona512 While that is the case, it does make it more tricky to fully troubleshoot, though in my case, 1 stick was bad enough that it was clear that it was faulty.

In a worst case scenario, if I end up getting errors while it is just at the XMP profiles and increasing voltages to the SOC and other aspects for stability do not help, then it will be hard or impossible for me to accurately narrow things down, thus I will have to hope I don't get 2 bad kits in a row.

I will be sending it back to newegg, and I will try to get a replacement as it is b-die, and would love to get a stable pair that I can then hopefully have some luck on tightening timings on.



While the box that it came in had a few dents, the memory sticks did not have any visible damage. Newegg mails the RAM out in a padded envelope instead of a larger box.
The QVL doesn't mean anything.
Many good ram kits are not included there.

What stability test did you run? I can not imagine 100% stability under these settings.....
1.5v is safe. And you can apply more v. Depends how you cool them.
Those results are @KedarWolf 's.

I have the same kit, but with a 3600 and my IMC can't run more than 3733.
