Procodt dual rank

Procodt dual rank. Only thing is not to go too high on the Ohm values on the highest end for procODT or DrvStr, unnecessary. AFAIK there are no 16Gbit Micron ICs. Could it be that 60 Ohm would be a better advice for dual rank RAM? Other people who have dual rank RAM can chip in and share which value works best for them. Any help is always appreciated. This led to greatly improved overclocking, and users can now get up to 4600 MHz on most top boards. An IC is the physical silicone on a PCB of the RAM stick that presents the capacity of a RAM stick. Procodt 60 I would even expect twr to do 10. Skill Trident Z RGBF4-3600C17D-32GTZR(2x 16GB dual-rank) 15-15-15-30 (2T) 13-13-13-28 (1T) 10-10-10-28 (1T) HyperX PredatorHX436C17PB3K2/32(2x 16GB single-rank) Zen 2: Dual Rank Micron E-Die overclocking >4400Mhz Hi there 👋 I currently struggle to boot anything higher than 4400 Mhz on my RAM (2x 16GB Micro E-Die). 4-58. 9 (lower temps) RttNom 6 (lower temps) RttWr 3 (lower temps) RttPark 3 (lower temps) the last 3 did not seem to help much. 38v 34. 0 settings only worked (the majority of the time) with two sticks. OP says he's done lots of Karhu so the memory appears okay, might be insufficient VSoC or an I/O to chiplet IF issue. 2x 8 , like near 28-30ohm, 4x8 or 2x16 like near 32-38/9 ohm RTTs are term-impedances on the mem side. 3 Ω for dual-rank memory. On AsRock x570 Taichi - cl16-19-19-19-36-56, mine prefer SOC/uncore 1. DarknessTheKiddd2 • R7 5900X 32GB Dual Rank However, like with ProcODT, too high of a resistance probably causes instability by way of signal absorption. 45v, likely 1. Jul 9, 2018 · There should be no risk playing around with the settings. 3~36. I have a 2666 dual rank kit that boots only at 68. 020v, procODT at 36. 1. The ram I have is also dual rank so 8 ranks instead of 4 at max fabric speed is working that poor memory controller to death. 2ns between them, but CL15 needs 1. (Single-rank setups often defaults to disabled-off-5, which means RTT_Park gets used for both idle and writes. Raising ProCODT is most often used to solve boot issues, occasionally VRM issues. VDDP. Apr 19, 2022 · Most Zen 3 can do infinity fabric/fclk of 1900, effective ram speed 3800. 3200 was the optimal clock speed for last gen, for this gen it's 3800, but you will also get almost the same performance with 3200 and it's much cheaper (and of course the latency is also an important factor). Dual rank is very sensitive to this parameter, only 0,900 volts work perfectly, at 855 there are sometimes errors 8. With ProcODT at 40, I've noticed some workers managed to finish selftest but other still failing. Mar 20, 2019 · (Hynix CJR 18 nm, Single Rank) Memory: 2x 8 GB G.

Apr 14, 2023 · Similar but the ProcODT is the ODT on the CPU, ODTs on the ram dies are like WR-NOM-PARK or such. VSOC should be between 1. Dec 30, 2018 · The procODT is very sensitive aswell, I can run at 60 Ohms at stock speed, but if I increase to 3200 I should decrease the procODT to 53 or even 48 Ohm. 00 if you haven't already. 9, VDDGs 0. 060V but if memory serves this is more for pushing past 3800. Looking for related arguments, will post when I find them. For those with motherboards from other manufacturers, a helpful approach is to start by adjusting the ProcODT parameter and test it using y-cruncher and TM5. 3-60 ohms, rttnom rzq/7, rttwr off, rttpark rzq/5. Do you see any improvement in the timings? tRCDRD can go to 16 but it gets unstable over 50 °C. I don't recommend using auto SoC voltages either. 0, VDDP 0. Given these are dual-rank and the additional bandwidth you get from that plus additional IMC strain it'd be about equivalent with 3733 single-rank at the same timings. Anything under 40 spit out errors in Dual rank is more sensitive to CLDO VDDP, and termination settings. I have been experiencing with overclocking my RAM for over a month in a machine that is running 24/7 and used for gaming, VMs, and creative work. You will get higher 1% lows and better overall fps in games with a DR setup. Aug 23, 2023 · In broad terms, the ODT and RTT adjustments presented in the table are suitable for GIGABYTE AM5 motherboards with a 2DPC (dual-rank, dual-slot) configuration and 8-layer PCB. RAM - G. I've started from scratch with SOC 1. ie: pseudo open drain (POD) pulling the data lines to tristate. But on AMD you should get at least RAM with speeds above 3000 MHz. As I mentioned earlier, users were faced with a huge number of problems when the first generation of Zen processors were released. 15V. Think the range was 48-60 of feasible ODTs. The absolute highest they will go fully stable (no errors at 3000%) is to 3600MHz 16-17-16-17-36-48-1T with GDM disabled which honestly I am super happy with. Latency will increase but the benfit of a Dual Rank setup more than makes up for it. 415 and lower is not stable at current timings) VSOC and VDDG are on auto. This limits how many ranks can be used, though sometimes more ranks can be used at a lower speed. Got this kit really cheap as an upgrade from my dual rank rev. 41V GDM disabled however. So, first thank you. Each module has two 64-bit in You might need to fiddle with the procodt values on your dual rank modules, but I don't know what-all you have tried in your overclocking attempts. Jun 9, 2016 · Hey guys. 00v and vddp to 0. Most of these ICs are eight-bit, so that eight ICs in parallel compose a single 64-bit interface. I was very confused as to what chips this kit used. Mar 1, 2021 · If we're stable at 2000, great! Now we can start by setting timings. What is an IMC? In general the Corsair dual rank specs had a tendency to not look very exciting, but they were actually not that bad, just very conservative bins. (two DIMMs, each with two ranks). The resistances and Rtts are worthwhile trying to copy, though every memory kit might like slight variations even though 6/3/3 or 7/3/3 is pretty common DR. Feb 7, 2020 · AMD modified procODT (on any motherboard), for which the optimal range now is 28–36. Since your is dual rank you might be able to run cl16-18-18 too, but it really depends on silicon lottery. My experience was with what seems like to have been 25nm 2Rx8 dual-rank Micron B-die.

I've found the Neo version of this ram F4-3600C16D-32GTZNC is dual rank, so my question is what is the difference between the Trident Z RGB (RC) vs the Trident Z Neo (NC) the specs are identical (32GB, 3600CL16, Timing 16-19-19-39) Mar 20, 2019 · I read that for dual rank memory the PROC ODT needs to be a bit higher, so it makes sense that I need 60 Ohm but the DRAM Calculator recommended 53 Ohm as preferred resistance. Rtt disable / rzq3 / rzq1 and rzq1 / rzq3 / rzq1 work better than rzq3 / rzq3 / rzq1. I used a ProcODT of 80 on some Dual-Rank 16GB sticks I was using to get it stable at 3200. Just Vermeer scales nicely between 30-39 ohm procODT. Says you should try to keep it between 40-60 for stability. For ProcODT, B550/X570 boards typically like 40 ohms or lower; B350 ~ X470 typically likes 48-60 ohms. 9–53. According to one Micron data sheet, this should be disabled for single-rank DIMMs and enabled for dual-rank DIMMs, but I have not tested this myself. E kit. G. ProcODT doesn't really matter (value wise, if it's between 34 and 60), it affects some other parameters but if it's stable, any value that's 60 Ohm or less is ok. 15v, iod to 1.

That fixed many of the issues. I'm using a 5900X running curve optimizer (-25 -20 -5) and a pair of 2x16GB dual-rank B-Die. but I see things like: "off" which should be "disabled" I guess, and then ohm stuff like "80 ohm" or "240 ohm", I don't see 1 or 3 in the RTT department. Instead of its default 48. 3800CL16 is still lower latency than 3600CL16 and ProcODT is an odd one that sometimes can work really well for stability and other times doesn't do a damn thing. Most systems use dual channel dual rank memory. I've tried every value from 34. The setting is there to aid stability with certain memory DIMMs. 0 x4 NVMe 1. 0 Hi, I'm having issues also, first tried to overclock my ryzen 5800x in a x570 msi tomahawk, apparently CPU is fine, but when running xmp it fails, tried upper procODT at 43. This has changed with 3rd gen Ryzen's memory controller, now the optimal termination block settings for single rank ddr4 dimms are normally 32-40 ohm procODT, rttnom off, rttwr off the procODT maybe a significant for boot up and push DRAM high frequency I just tested memory bus speed from 3000-3333MHz for 3000-3133 with procODT 60 ohm (auto), there are no major problem. Multiple ICs make up the full capacity of the RAM stick and come in single rank(on one side of the PCB) or dual rank(on both sides of the PCB). It seems ProcODT had the biggest impact how long it takes for the test to fail. 3 3D-NAND TLC (MZ-V7S1T0BW) 850 Watt be quiet! Straight Power 11 Modular 80+ Gold be quiet!
