Looking for a budget-friendly Samsung B die?
No available choices. In DRAM voltage configurations there are DRAM Voltage, DDRVPP and DRAM Termination settings. Attempted to raise the latter two by roughly 20% but no change occurred. Double-sided DRAM remains capped at around 3200Mhz on this board.
You can boost DRAM termination resistance, which aids signal integrity, though it’s typically a high-frequency consideration. VCCSA and VCCIO aren’t located on the RAM settings panel—probably in the CPU section. I’m not an Intel CPU specialist, just doing my best to assist!
Yeah, 2T. Setting it 1T it only boots just around 3066Mhz Found those VCCSA and VCCIO voltage Intel equivalents from CPU voltage settings but fiddling with them brought no luck of lowering timings nor overclocking with looser timings. Also it's painfully slow to boot new RAM settings, so I'm calling it quits. But perhaps on another platform it will OC, well, at all.
Hello there. You're facing similar challenges. After buying the G.Skill F4-3200C16D-16GTZRX, you discovered it's a Samsung B-Die model. It works well on b450 boards but struggles with your B350-F Strix setup paired with a Ryzen 7 1700. Setting the DOCP profile gets it to boot, yet TestMem5 reports numerous errors. I've reduced errors somewhat, but never completely eliminated them. The best I've achieved was without DOCP settings and by manually tweaking timings and voltages. Currently, it runs smoothly at 3000MHz CL16, but I need it to operate at 3200MHz CL16. I've tried everything—DRAM calculator, timing data from other boards using DOCP/XMP profiles—but nothing stabilized the issue. Reading about ProcODT helped a bit, though I couldn't fix it fully. Adjusting the CAD resistance in the BIOS often causes crashes, forcing a CMOS reset. I pushed RAM voltage up to 1.52V, which slightly improved stability but still left many errors. Now I'm at 3000MHz CL16, and I'd appreciate any guidance from others. Good luck with your thread, Alex. Cheers.
Sorry for the delayed response; I gave up on it but reconsidered after the latest BIOS update 5406. How do I determine which BIOS update preceded the 2nd generation Ryzen release? =/ I’m sorry for bringing this thread back, but I’d prefer to post here instead of creating a new one. Edit: I found the solution. I simply checked the BIOS update history for my motherboard and selected the one before the version labeled “Update for upcoming Ryzen processors.” Another question: If this doesn’t resolve my issue, which option is preferable—upgrading the motherboard or the CPU? Should I opt for a B450 board like the MSi B450 Tomahawk Max, or should I choose the Ryzen 5 3600? Which factor matters more? Logically, upgrading the CPU seems better since it offers a noticeable performance boost with the Ryzen 5 3600, but will RAM play a significant role in that decision? It would help to know what you think. Thank you for your time and assistance. I plan to sell my old motherboard or CPU. Edited June 1, 2020 by napstericious found an answer, but now I have another question.
A minor adjustment made after noticing discussions on forums about this part being a "cheap Samsung B-Die variant." Reddit users and overclocking communities have labeled it as "budget," "poor performance," "bad," or "affordable" compared to other options. I clarify that my setup uses a G. Skill TridentZ Royal Gold kit with 4800C18 XMP, which includes the K4A8G085WB-BCPB exactly. The die is 20nm and cannot be considered a "budget" or low-end variant.
I believe you misunderstood my message. Many are noticing the part number K4A8G085WB-BCPB and assuming it’s a basic or low-quality component. They assume all dimmers with this code are budget options and that the actual quality is hidden under another part number. My reasoning comes from regularly swapping parts like hardware, RAM, GPUs, and CPUs. I’ve seen friends and enthusiasts searching for Samsung’s internal codes and concluding that K4A8G085WB-BCPB points to a cheaper, less reliable die. They think there’s a special "magic" part number that gives better overclocking results. However, my 4800@CL18-XMP uses the same exact code and functions perfectly at 4800@CL17 without any problems.
