Specs: Ryzen 3950x, Asus WS x570 PRO ACE, 32GB Crucial ( BL2K16G36C16U4R ) ram, Bequiet Dark Pro 4
Long story short, I have spent over 40 hours, 12 of which were probably just watching the "highly recommended" videos from "BuildZoid" including him "going shopping for ram" to get where I am today... finding this whole exercise to be something where I am quite literally making ZERO progress considering I have probably reset my CMOS over a 100 times during this progress.
I made this post 12 days ago: https://www.reddit.com/r/overclockin...and_a_3000c16/
and didn't get anywhere, so ended up buying a 3600C16 Rev-E kit that "BuildZoid" recommended on his videos as the previous post didn't get my 3000 D-Die Micron kit stable past 3200, and wanted 3600 to squeeze out more a balanced performance on my Ryzen 3950x
Well, today the new kit arrived.
So I loaded up Taiphoon, Read the SPD, Displayed Timings in Nanoseconds, and Saved the Complete Report in HTML.
Then Typed the info into Dram Calculator, "Imported my XMP" profile, which shows my "Memory Chip Quality" as 114% and "Overclocking Potential 4723Mhz C16" https://imgur.com/a/4Vbcc9F
(yeah right! When I try to pick anything above 3866, in DRAM Calc, it just says "NOT SUPPORTED") - Anyways: I tweaked all the timings, DRAM, SOC voltage, etc as shown on the "Main" page of the DRAM Calc -- see screenshot with Compare Timings ON: https://imgur.com/a/hAgC9NY
-- Did a Prime95 run of "LARGE FFT" to test memory stability -- crashes in under 5 minutes with errors.
So I repeated it, this time using the "Default: R-XMP" (purple button) to generate timings, which showed my kit at "96% Memory Chip Quality" (quite a stark difference from the above Imported HTML showing 114% -- what gives??) -- anyways, went with the "FAST" profile to get it down to CL 14: https://imgur.com/a/CRm6qS5
-- (look got everything matching) same thing, boots, and then with Prime95 LARGE FFT to test memory - crashes in under 5 minutes with errors...
I also tried simply stock XMP, but, tried to increase the FCLK to 1833 and manually changing the memory from 3600 to 3666 (untouched stock timings) - and the thing didn't even boot. I know my cpu can do 1833FCLK because with the older D-Die Micron kit, when I decoupled the FCLK from MCLK I was able to get in Windows at 1833MCLK - and this kit doesn't even post to 3666 .... with 1833FCLK, when I know it did 1833FCLK before on the old 3000 Kit!
I am so frustrated, this is my FIRST AMD build in over 25 years, and I have never, ever, had to spend so much time to get "Optimal" performance (i.e. low speed ram = baaaaaad cpu performance, not tight timings = baaaaaaad cpu performance) - and on top of that I bought this new kit, that doesn't seem to be stable, at all even at the "Safe" settings considering my chip is 114% of the quality???
Am I missing something really obvious here...?
Thanks for your help!
