Ok. It passed memtest86 with 4 passes at both stock and the xmp speeds. Took all day and night to run both tests. It seems to be more stable setting it to manual and inputting the xmp primaries and voltage manually rather than enabling xmp. I had a usb stick with it on from a year ago from testing the Patriot set(s) that I had gotten then. Had a total of 3 doa and 1 faulty then. Went through 8 sticks to get 4 that worked.
How do I set up prime95 to test the ram only? Minimum voltage increment for the ram on this motherboard is 0.005. Is there any issue with the reported voltage always being lower than the voltage that is set. The xmp for the kits is 1.45v. Motherboard and HWi report it as 1.44v fluctuating between 1.32v and 1.48v depending on system load.
TM5 also ran for a few passes not without any errors kicked up. I'm not sure what changed in the last week. Other than I had the kits removed to test one at a time before putting both back in again. Possibly there might have been some debris that got in there the first time I seated them that caused the initial instability that has since been cleared out?
What are the secondary and tertiary timings that should be done? I've seen posts about ram being temperature sensitive depending on the timings used. Assuming the hottest stick that I've seen gets to 49.9c when running TM5 for 7+hours. Mostly temps are high 30s to mid 40s so far, otherwise. They'd be a bit cooler, but I don't have temperature control for my room. My landlord keeps the place between 27-32c ambient on average. I'd prefer ambient to be around 22.5c.
if you're lazy and want the quick fix but still staying at your XMP profile enabled:
ProcODT: put it at 43.6 or 48, since you got 4 Ranks (4x8GB) of ram i suggest you to start at 48
RTTNom: 7 or (34 Ohm)
RTTWr: 3 (or 60 Ohm)
RTTPark: between 3 to 1 (or 60 to 240 ohm)
AddrCmdDrvStr: 24
RTT value is RZQ/240, means if you put 3 for example, it would mean 3/240 which results in 60.
and if you really want to push/optimize the secondary and teritary, you could try this:
tRC: 50 (tRAS+tRP)
tRRDS: 4
tRRDL: could go as low as 4, but try 8 then 6
tFAW: 16
tWTRS: 4
tWTRL: could go as low as 8 or 6 , but try 12, then 10
tWR: start at 16, then you could try to go as low as 8
tRFC: put it at 560 for start, you could fiddle with this as low as you could AFTER you've done tweaking all other timings since tRFC could be sensitive to temps, i myself prefer to get all secondary and teritary timings as low and stable as i could with tRFC at 560, then start tuning.
tRFC down as much as you could
tRTP: try 12 then lower it by 2, maybe could go into 8
tRDWR: this one yours are really high, standard XMP kits i ever bought usually starts at 8, so put it at i
tWRRD: put it between 3 to 1, i suggest start at 3
PowerDown: Disabled
try to go as low as you could, then if everything seems booting with the tightest or your desired timing, test it with TM5 Absolut config for 3 cycles.
alternatively, you could try to loosen the primary timings first to this:
tCL and tCWL: 16
tRCDRD: 16
tRCDWR: 16
tRP: 16
tRAS: 36
tRC: 52
you could also try to fiddle with the LLC for SOC (and the cpu if you want), it does help me sometime when tweaking ryzen imc. just keep in mind, b dies are kinda sensitive above 50c usually, so i think it is kinda better if you did drop the voltage and be smart with the available LLC options, with the sacrifice of loosening the primary timings and the tCWL, since tCL = tCWL, but if you could do tCL - 2 for tCWL. combination of greater secondary and teritary timings and lowest possible voltage, wouldn't be all bad for the primary to be loosened a bit. b dies could do 16 flat usually, so try it out the best combination and it will took hours if not days if you aim for balance and perfection for both timings and voltage.
Dont forget to update youe mobo bios to the latest and chipset driver to the latest (ver 4.11 as the time im writing this)
