    Core binding is the key here. If you can pin each thread of your program on each physical CPU, then do it. If you can't, then you will rely on the OS scheduler. Check if each CPU core has a load. It doesn't matter if some threads are on the logical cores as long as the corresponding physical cores are idle.

    The AC plugged in sometimes supersedes the power saving features, and also makes the battery and stuff warm. Try unplug and see if it's better. If it's turboing, then it's NOT idle. Try kill every background tasks, including the web browser and the NZXT program (use CPU-Z or something lightweight instead to check each core frequency).

    Yay! I manage not to break any hardware this time, and also not to win a prize! Coincidence?! Wait... not "yay", the other thing Still great event

    Waw! OMG I'm a prize winner, am I?! It was 2 weeks of madness here... My 7820X was screeming every night because I left its overclock on, and during the day I put my 2080ti at 150W powercap so it's not summer in my self-quarantine appartment already! It was jet-engine noise all nights long... And you know the best part? After 20 days of folding (I started earlier than the contest), I just had a major power fail due to my failing UPS! The RAID5 checked no error (after 12 hours verification...), so I'm still happy @GOTSpectrum here is the winning proof: 95 Mesterial Mesterial 25,017,090 410 14 25USD Steam Gift Card I'm pausing folding for the time I change the battery of my UPS, so to account for that, I got an LTT folding shirt Thank you for this great event!

    Hurray, my LTT WU has finished and was properly uploaded! ^^

    Basically, you're looking at atoms that are parts of some proteins, interacting with a forcefield. Mostly, they are the proteins at the surface of the human malware, which are responsible for all the things it does (interacting with human cells, antibody recognition, etc.). Or, some drug targets, i.e. proteins or molecules that are supposed to interact with the virus surface proteins.

    Folding from LTT server once again! ^^ Let's hope there will be a correct CS connection this time!

    Maybe I'm missing something, but shouldn't the project need more AS and not WS? Based on this page: https://apps.foldingathome.org/serverstats

    Just imagine the kooling required for those... Not to mention 5 nodes per rack because of the power ?
  10. Mesterial
    I'm not sure they are monolithic, the socket looks more like 2 sockets side by side. For AMD, they are all multi-chiplets.

    Power is going insane on the Intel part, if you ask me... The 9282 is 400w TDP, that's 800w only for the CPUs of a single node !! ? I might be an Intel fanboy, but sometimes I hardly understand the last years decisions...
  12. Mesterial
    These are only theoretical values! You have to introduce the HPL efficiency, which is a catastrophy for Intel at AVX512 frequency compared to base clock.
  13. Mesterial
    30 blades, so 90 nodes, at max. (I know it because I work there, and participated in the bench of these!)

    In conclusion, I went as far as 2*4.8 GHz + 2*4.7 GHz + 4*4.6 GHz, at 1.28 Vcore, letting all power savings, for 24/7 safe use. I'm happy with it ?
  15. Mesterial
    Oh, and the best part: the max delta between cores went from 16 to 10 degrees!! (at 100% fans and pump)
  16. Mesterial
    And now, the results! i7-7820X, 8 cores, 140W, 4 cores @ 4.6 GHz (0, 2, 5, 6) and 4 cores @ 4.4 GHz (1, 3, 4, 7) (cores chosen by Intel ranking in the BIOS) Corsair H115i Max temps at Windows idle: 54 40 39 39 40 45 40 38 -> 45 35 32 32 31 33 31 32 (-9 -5 -7 -7 -9 -12 -9 -6) Min temps at Windows idle + fan/pump at 100%: 31 29 29 30 29 30 30 30 -> 31 28 29 30 28 30 30 30 (0 -1 0 0 -1 0 0 0) IntelBurn HPL (AVX), 4 GB, 20 times in a row, fan/pump at 100% Max temps: 82 88 88 94 92 91 83 79 -> 72 74 76 76 74 75 68 68 (-10 -14 -12 -18 -18 -16 -15 -11) Max score: 210.15 GFLOPS -> 210.40 GFLOPS (91.2% eff. -> 91.3% eff.)

What is funny, is that min idle temps at full blast fans are the same! Also, what is amazing, is that I can now run a surprise HPL without fearing a meltdown lol! I guess this is where watercooling shines, now that it should be the "limiting" factor. Maybe I will put the 8 cores at 4.6 GHz, of even 4.7 ? So, even for the small 7100T, I am very happy with this delid frenzy that got into me. Of course I will do it on my parent's computer (3 series), but too bad my computer I got there is a soldered i7-960 though!

    I'm done for today ? So, the delid was very different from the small CPU: the silicone was somewhat softer, so I first thought it didn't work because the IHS was back at its place when opening the tool. Everything cleaned: It was very time-consuming to clean VERY carefully the seal, because of the tiny components. They almost touch the silicone, so I started scratching from the opposite. It's not hard, it just requires some patience (along with the ifixit tools !). Then, the nail polish on every components: And finally, the liquid metal, the silicone, and the IHS!

    OK, but you have an AIO, and not a midget CPU. The temperature is more important than the delta. At some point, you can't go bellow a certain temperature with the same conductor. The heat generated is kept the same, it's just the speed at which it is evacuated that changes. 73 W/mK, I mean, the i3 is just 35W max TDP, and around 21W during HPL! And with the Intel crappy cooler. Now this, is the real deal: ?
  19. Mesterial
    So, a little drop of Noctua NT-H2 and reassembling. Let's check the results! Remember I use the 1 cm height Intel stock cooler… I report the temperatures from Coretemp, so only core temperatures (core0 and core1). i3-7100T, 2 cores, 35W Max temps at Windows idle: 45°C 47°C -> 39°C 41°C (-6°C -6°C) Min temps at Windows idle + fan at 100%: 31°C 31°C -> 28°C 27°C (-3°C -4°C) IntelBurn HPL (AVX), 2 GB, 20 times in a row, fan at 100% Max temps: 60°C 59°C -> 54°C 51°C (-6°C -8°C) Max score: 48.54 GFLOPS -> 49.20 GFLOPS (89.2% eff. -> 90.4% eff. !) Extreme HPL (AVX2), 3 GB, 5 times in a row, fan at 100% Max temps: 61°C 61°C -> 54°C 53°C (-7°C -8°C) Max score: 78.12 GFLOPS -> 82.14 GFLOPS (71.8% eff. -> 75.5% eff. !) Extreme HPL (AVX2), 3 GB, 5 times in a row right after previous test, fan at auto Max temps: 66°C 66°C -> 61°C 60°C (-5°C -6°C) Max score: 81.90 GFLOPS -> 83.04 GFLOPS (75.3% eff. -> 76.3% eff. !) (best scores compared to full fan due to cache I suppose) WAW!!! I am really impressed for such a small CPU, using the Intel stock crappy cooler. In few hours, I will start the process for the big one… ?

    So, I had some time before Sunday to start the deliding of my good old SilverStone "TV" ? Hi there, smallest PC I own! ? Notice the Intel stock smallest cooler, as the i3-7100T has a TDP of only 35W, IGP included! Aligning the triangles... And closing the box... Hang in there, little one! This part is so scary… I had to open and check three times… And then... It's done! OMG! There's no going back now... So let's open it, and... OMG it's soooo small!!! ? Ain't it cute?! Time for some cleaning. For the TIM, I use some alcohol. For the silicone seal on the IHS, I use some "petrol F" (or zippo fuel?), it helps removing adhesives, and then some alcohol. I let a little bit of silicone at the "opening" of the seal to mark it, as a relid guidance. For the PCB part, I just scratch the seal with the iFixit tool. It is very practical, I was impressed! No need to wipe it completely with some chemicals. Then, even if it's clearly not useful, I put some nail polish around the die as a barrier, just to test the nail polish brush. I read somewhere that the 4 dots are here to check the temperature, so I did not touch them, just in case. And now, the liquid metal... I'm aware of the very impractical syringe and the mess it can create… So here is my Haagen-Daas cap liquid metal battle station! ? OMG I'm so glad I was warned about the impractical thing… The first drop just dropped right away in the cap, and was too big! I could suck it back in the syringe, and start over. The applying cotton candy tool is very good at spraying the drop into a very thin layer. I applied it a little bit too much area on the IHS, but not too much thickness, as Steve's Gamers Nexus teaches ? So it's ok I guess. Now time for the relid. I choose just to put 4 silicone drops at the corners, and 2 lines for the socket grips. I'm sorry, I missed to take a picture before reliding. And finally, the rocket press. The silicone did not make a mess, so I'm glad! Now time for the seal to rest. I'll reassemble the PC tomorrow, and do the same benchmarks I did this morning. But I'm not expecting rocketting performance, this CPU is really small, and with the Intel stock cooler… But we will see that! ? Pro tips: on the floor, you can't drop things! ?

    Hi there! I know there are a ton of stories about it, but I just want to share my on-going experience with this. ? Soooo…. After watching so many videos of LTT and Gamers Nexus, and being so angry about my i7-7820X temps for so much time, especially having 20°C max delta between cores (which appears to be normal, but whatever), I went for some shopping. Yes, I feel confident enough to delid my little big boy CPU! ? Those Rockit tools look and feel awesome quality, despite being 3D printed! It's very reassuring. They are made in very hard plastic, I was very surprised about their hardness. I bought of course the Rockit 99 for the LGA2066 socket, but also the Rockit 88 for both LGA1150 and 1155 sockets... Why? Well, to train first on my "TV" PC, equipped with a small i3-7100T! And then, maybe I will also do it for my mother's computer (i5-3350P) so her CPU stays cool whatever she does (those fff**fff webpage ads can be CPU hungry sometimes....). I mean, an i3-7100T is cheaper to replace than an i7-7820X in case something goes wrong… Also, I chose the Rockit tools over the tools from Der8auer, because although his tools are made of steel, let's face it, I could buy both the Rockit tools for about the same price as just his Skylake-X tool… It's not to criticize of course, but it's a little expensive. Anyway, I bought all the tools from Caseking.de, so in a way, he has my money already! ?? I got every tools needed: an iFixit toolkit to help removing the silicon adhesive once delided, some UHU high temp silicone for reliding, some Noctua NT-H2 paste to put on the IHS (why not replacing my Artic MX4 by this all brand-new even higher performance paste), some Thermal Grizzly Conductonaut of course, and some transparent nail polish, which is the good sh*t according to Gamers Nexus! I read every transparent nail polishes in the store! Beware those Maybelline ones are "rich in iron", that's too bad for a non-conductive purpose! ? I will start working on it on Sunday, I will then feed this post with pictures, results and stuff. I'm so excited about it, I had to share this post ?

    It is cheap, no worries!
  23. Mesterial
    Oh ok... But why bother using a DP adapter? Just buy a DVI to HDMI cable!
  24. Mesterial
    I'm in the same situation for my 3 Asus VG278HE. I use 3 of these adapters : Club 3D CAC-1051 Costy, but efficient.
  25. Mesterial
    They DO exist, I am using 3 of those as we speak. But a single one cost 100-120€... It is the best: Club 3D CAC-1051
