The system has run stable since my post last night. Will be interesting to see how the 3950X benches in September when it is released with two golden sample CCD's in the classic workunits:20,676 CPU time:74,226 hours One golden sample and one turd, as someone posted about the 3900X cpus. Might be some differences compared to the 3700X tests since I will have two CCD in my cpu. When I get my 3900X in and installed, I will be running the benchmarks also and expect to shift from the SSE41 app to the AVX r3345 or r3712 application for the cpu which I bet will be faster. Notice the older AVX apps are now faster than the SSExx apps now. RueiKe posted in the Ryzen and Threadripper thread his test results on his 3700X. But the AMD processors don't penalize AVX instructions by turning down the clocks like the Intel processors do. ![]() Hyper 212 evo install into an amd cpu full#The floating point register is now a full 256bit width so can process an AVX instruction in one clock cycle just like Intel. The improved math functions in Zen 2 put it on the same level as the math performance of Intel, actually a bit better now. That also prevents the cpu voltage from being overcooked as it drops the cpu voltage down to the base clock VID voltage from the lookup tables. That is what I have been doing with my Ryzens. Hyper 212 evo install into an amd cpu manual#You can always disable Auto overclocking and set a manual all-core multiplier. The Ryzen old-timers are using negative offsets to get the voltages down and the temps under control. I have been reading very similar reports that the Auto voltages are unnecessarily high for some reason. Interesting to hear about the AVX instruction and no declocking - its been awhile since I've been on AMD. Hyper 212 evo install into an amd cpu how to#I would be fine with locking the 3900x to 4GHz or even 3.8, if it ran all cores, just not sure how to do that with the new motherboard BIOS (if its possible) I don't want to spend $50-100 more for just a few degrees of cooling - but I do want to run these 8-10 of these cores (and 16-20 threads) for Seti! The Hyper 212 Evo always worked well for this 4790k and the AMD CPU it replaced (Phenom II X6) - so the prices of the Noctura or AIO coolers made me hesitant. I have an older Antec 900 case which has a big vent fan at the top, 2 front fans and one back side. Temperatures looked much cooler - seems to be around 68C with SETI running for several minutes. So I found that the ASUS Motherboard (Prime x470-Pro) is setting the CPU voltage to 1.45 and it should be 1.25, so I manually set it to 1.25. Same for the 3900X I would think even with the process classic workunits:20,676 CPU time:74,226 hoursĪ proud member of the OFA (Old Farts Association) The 2700X won't do 4Ghz+ without water cooling with an AIO. It ran overnight on both cpu and gpu tasks when I was testing it out with no issues. I have the Wraith Prism cooler on one of my contest machines that I just upgraded to a 2700X that is running at 3850Mhz. The thermal compute load that needs to be dissipated is 142W at stock. You should either purchase a air cooler with the AM4 mounting hardware or think about a 240mm AIO cooler. You can try and manually underclock the cpu to around 4Ghz all cores and see if that drops the temp low enough to prevent thermal shutdown. The Wraith cooler is not really suited for 24/7 compute loads unless you have very good case ventilation to assist. This is why I usually wait when new tech gets released - let others work out the bugs -) but I really wanted the 3900x for SETI !Įverything sounds normal. ![]() This is with 6 CPU Tasks (I had 12 CPU tasks before rerunning Lunatics.)ĬPU is supposed to be 3.8GHz with boost to 4.6GHz, but while monitoring, I am seeing the speeds on the cores up around 4.3GHz, even though the temp is rising. I am fairly certain that I have the cooler installed properly and reapplied the thermal paste.ĬPU seems to idle from 44-54C, but as soon as I start is jumps quickly to 80C, and takes about a minute to cool off after I hit suspend. Turns out I can't install the Hyper Evo 212 - its old enough it doesn't support AM4 mounting.
