7745HXは最大でも75wでそれとは。 P12は風量あるファンですよね。 高負荷時に触ってもそんな熱くないし モバイルなのでヒートスプレッダがなくダイ直でヒートシンクが触れてるので熱伝導がよくないのかもしれませんね。

@@twinyuki 7745HXも一応100W級出るらしですが、うちで75Wや65Wに設定してもやっぱり直ぐに91度まで上がってました。 P12Maxはどこぞの店頭で他機と見比べて静圧が高い方だったので選びましたが、暖まり方は他の弱いファンと同じ感じでした。 他所のレビュー動画でダイとヒートシンクの間のグリスを変えてもあんまり変わらないって話も聞きましたし、やっぱりヒートシンクの問題ですかね。 （それでも性能十分だったんで普通に使ってます）

@@schalldampfer9315 やはりTDP設定は効いてないようですね。高風量だと板に当たった風が跳ね返ってきてあんまり意味なさそうなんですよね。反対側にして吸い出した方が少しだけ冷えがいいです。

GPUマイニングの時代は2022年で終了して、現在のGPUマイニングは日本の電力コストで計算すると一番稼げる4070tiで一日20円程度の利益です。 CPUマイニングだけが何とか生き残っていてこのマザーだとまだ1日100円くらいの利益が残ります。

今メモリも輸入しようとすると32GBで1本2万円くらいですね。12CCDだと容量がどうかに関係なく12本必要になるので高くなりますね。

I bought it as a set with the motherboard on eBay, but recently there have been fewer listings for it. It seems that only the CPU is sold on Aliexpress.

I am thinking about buying one but not sure if it will work properly. Btw do you live in Japan? I thought ebay has a high shipping charge here.

@@SadmanAhmed-ij6om Since it is not a general CPU, it may not start unless it is a combination that has been confirmed to work. US sellers on eBay have high shipping costs, so I buy from Chinese sellers that I think I can trust. Shipping costs from China are cheap.

Got it. I will also try to find a pair so that it has a higher chance of working. Thank you.

@@ReLiveHD Work efficiency is declining. EPYC tends to adjust the default TDP to be most efficient.

ES has less restrictions, but the maximum magnification is lower, so it is possible to change the P0 state manually.

​​@@twinyukithank you. Do you know that software which can help me increase the p0 and boost frequency?

@@lymarwasii5667 Custom Pstates can be defined within UEFI. However, there is a high possibility that it will not work as expected due to various limitations such as power supply.

I checked the bios of H13SSL motherboard.. unfortunately there is no option to change the P-State o frequency of the the processor. Sad. I wanted to overclock it to the normal frequency of 2.7 GHz base and 3.85 GHz boost. But I don't see any possibilities.

If you log in to IPMI, the POST code will be displayed, so you may be able to find the cause. Poor socket contact, often with incorrect torque.

どうもありがとう ​@@twinyuki I will buy a torque wrench and mount the CPU correctly. Thereafter I will check IPMI, since it is new for me. I appreciate your help!

Update: I connected old VGA monitor and I got the picture of boot screen. After the logo I starts initialization and afterwords it shows black screen (though video signal is available). I logged in into ipmi and saw the post code a2. In all this time , I did not see any notification about BIOS . I pressed keys DEL, F4, F8, F10, F11 to enter into bios, but it did not work. My wish right now to enter into bios. Should I just add an HDD so that motherboard permit me to enter into BIOS? I would appreciate your ideas.

A2 is related to IDE/SATA, so if it is not connected, it may not be related. Try updating to the latest BIOS via IPMI. I also had problems with USB keyboard operations with BIOS 1.1a. The key to enter the BIOS is DEL.

I appreciate your answer very much. Now I get the post code ad : "ready to boot". Following things I did: I have removed the M2 SSD and connected SATA SSD only. Also I have mounted the CPU and the fan with correct torque using torque wrench. The BIOS version is the newest: 1.6. Even doing all that, I still was getting the code a2. Thereafter by accident I discounted the USB dongle for wireless keyboard and the PC now starts all the way to the post code ad "ready to boot". But the screen remains black after the boot and initializing process. I still don't have video card connected. Is there any jumper on the motherboard that I need to change so that the screen does not remain black? Currently waiting for a wired keyboard to arrive. Let's see if I can enter into BIOS with it.

Have you checked out Thradripper? Server motherboards are weird, so If you can't use up more channels and cores, the 7950X or 7950X3D might be better. However, it can store an overwhelming amount of memory.

RAM?

You're a cool girl. Please help me. I bought an H11DSi-NT v2.0 motherboard and two CPUs AMD EPYC 7D12. And it won't start. The seller said that it worked for him. On the forums people write that it should not work!

@@user-oe8he8dl6g Hmm, I also have the H11DSI, but I haven't checked it because I don't want to disassemble it. I couldn't start it with Asrockrack's ROME2D16-2T, so I contacted the seller and was told that it wouldn't start even in 1way with Dual Socket.

Thanks for your comment. Unfortunately, this motherboard broke today so I can't measure it. I changed the PPT to 105W and it was about 19kh, so I think the measurement at the wall would be about 150W.

With this CPU, the memory is limited to 4 channels and the TDP is low, so the hash rate of Raptoreum was 4200h / s. Zen 2 has enough cache for each thread, so even if you change the memory from 4 channels to 1 channel, it will not decrease.
