good

...this seems to fit somewhat (time-stamped), might add even more confusion re. Bitcoin

...speaking of uncertainties, well over 1,000 point swings in the Dow stock index today...what uncertainty looks like, coupled perhaps with some market-maker interventions

...well, they are all also 'asset classes' and as such very much related / correlated in their movements. Right now, there's huge perceived uncertainty re. 'next steps' in the pandemic, supply chains, inflation, and a real danger of armed conflicts...financial markets in general don't like uncertainty. ...also, Russian wealth has relied heavily on crypto to move funds outside of official international sanctions and banking controls, but that flight of capital won't please the (Russian and other) state(s) too much. Finally, the age-old problem with crypto: The more successful and widespread it gets re. payment acceptance etc, the more the monetary authorities will try to clamp down - a victim of its own success, so to speak. Ultimately, governments want to control monetary policy and enforce fiscal policies (taxes), and they don't like people 'making their own money (> crypto)' - go figure All that said, crypto may very well remain an asset class to hedge against uncertainties (and perhaps inflation once crypto values have calmed), and many folks will like some part of their apparent wealth outside the grasp of 'the authorities'. However, the major crypto coins are also subject to much wilder speculation if not manipulation, and thus riskier to park wealth in. If it all goes terrible wrong, we might just find ourselves back doing barter trade

...EVBots come up for sale every once in a while at HWBot (> example) or even recently at OCN (one sold last month or so). Not sure about pricing though for just the EVBot by itself (often sold in a package). Probably a lot more than US$15 a piece / new I paid some years back - but w/ 8x older Classifieds / KPEs, I have to hold on to mine.

I love the Classifieds (have a few GTX 780 Ti and up), especially w/EVBot ...for the GTX 580, it might also be nice to find a > MSI Lightning Xtreme . With most custom-PCB GTX 580s, you need a really sturdy PSU if going sub-ambient or lower and pushing up the PL

Good Progress ! With these Ryzen 5K, lots of permutations and combinations to find 'that setup'. FYI, per HardwareUnboxed vid, 4 sticks of Dual Rank > 2 sticks of Dual Rank, but not that drastic a difference. Re. your Aida latency...there might still be some room (ignore the ZenTimings IF2000/DDR4 4000 at lower right - not fully stable yet). My daily setup latency w/ 4 sticks SR hovers between 54ns and 57ns

...yes, that's how I find my way around ...though sometimes I have to stop and ask for directions...

FYI re. the RAM issue you describe: 4 sticks versus 2 sticks, and SR vs DR - all makes a big difference in Ryzen 5k

...probably, though it seems sturdy and does run quite cool - cooler than the 'regular CH8 Hero Wifi right next to it (pic in my sig) with a similar cooling arrangement. Anyway, I really like the Dark Hero; it's a fun board to push, especially w/Dynamic OC with which to get top multi-core and single-core results at the same time with just a few simple steps.

Kudos for your clean methodical approach to do one step at a time . There's still extra performance to be had with the 5950X / Asus X570 Dark Hero (I run of of those), but I am sure you will do more step-by-step updates, apart from pointing out the 'DynamicOC' feature on that mobo / CPU combo. It doesn't require sub-zero cooling, btw

8K@60Hz via DisplayPort 1.4 passthrough, that sort of thing 40 Gbps are good for... source

...you really are making me think about re-assembling my old 939 'puter...may be it got faster after ten years in a dark basement storage room

As @Avacado already pointed out, the number of cores in a radiator just refers to the number of tubes that are arranged more or less side-by-side, but still in one single cooling liquid circuit. I use dual core and triple core rads that have either four or five ports, but they are all connected to each other...leave one open and all of it will drain out . Dual and triple core rads tend to be much thicker than standard rads: single core on the left, triple core on the right: You're probably thinking of a classic liquid-to-liquid heat exchanger with two separate liquid circuits, ie....

Great - I was actually thinking about adding a PortRoal thread...love PortRoyal ...I'll start with 2x 2080 Ti at 21060 and 1x 2080 Ti at 10278 ...it's been a while since I ran the 2080 Tis in PR, including for 3Dm HoF. Time to revisit that updated system (now Raven_B) soon ! GPUs for below are stock-bios and w-cooled; system was/is Threadripper 2950X ... 6900 XT is next with 11701...this run is fairly fresh (a week ago or so?). 6900XTs are beasts in TimeSpy et al, but PortRoyal / RayTracing not so much...still, good enough for most games w/ RayTracing. Card is water-cooled, processor is 3950X (stock) ...3090 Strix / 5950X is getting an update, but look forward to add that soon.

...temp changes of push-pull will depend on components and current idle vs load scenarios. In my case, using triple core copper rads (64mm thick +-) and fairly tight fpi meant that push-pull was more or less a given. Also, you can move a lot of air with push-pull w/o annoyingly high and loud rpms. For push-pull, you always want to use the same model of fan.

Arctic P12 bundles ? Don't know what you mean The Arctic P12 psts are not only a great deal, their performance is really good...I replaced a whole bunch of older but still fav GentleTyphoon AP 29 3K rpm fans (and some Sunon 5k rpm server fans) with the Arctic P12s in push-pull on custom loops as well...in push-pull, they perform about the same as a single GT at full song, but are way quieter, if not near-silent. Their top speed is around 1850 rpm, with 1200 rpm 'default' per bios. I still adore the GTs, I just don't want to hear them...

...blame it on the cat, why don't you I like the refill option as well, though I cleaned and re-filled an old TT 240 (9 years and running now) not that long ago by taking the Asetek cold plate off. As to the BeQuiet PureLoop, I used it first on an oc'ed 8c/16t Intel 5960X quad-c, followed by a 3950X and then 5950X while I was building up the custom w-loops for those two. For the 16c/32t CPUs, I took the regular BeQuiet fans off and mounted 6x Arctic P12s psts in push-pull...the regular fans are decent enough performers, but Arctic P12 pst in push-pull made a clear difference - enough to allow the system to boost to higher sustained clocks.

I just rewired everything in my home-office with Cat7 and Cat8 (don't use wifi) and our building offers up to 10 Gb/s up-and-down, but I find that apart from my mobos only supporting 2.5Gb/s (which could be dealt with via a descrete card), the real problem is reasonably affordable and available 10 Gb/s routers. Hopefully those prices will come down and availability goes up. Re. PCIe 6, while PCIe 5 NVMes are just coming out into the consumer space now, PCIe 6 drives should be fun, especially with 8 and 12 channel DDR5 RAM for HEDT & up.

How do you like the BeQuiet PureLoop ? I've picked one up for an office machine in March last year and really like it. As to RGB, I find it harder to come by equipment that doesn't have it anyway whether I like it or not, but I made peace with it by setting everything to Cherenkov radiation blue - it 'works' when the smoked glass panels are on.

Ain't real competition grand ?

FYI, I would be very careful with methanol... There's the compatibility of the o-rings and other materials in your loop(s) I already alluded to before. Also, with continued high voltage and amps, some components may eventually let go with a bang / flash (been there)...with that in mind, methanol ignites easily but the flame is very hard to see.

..speaking of temps, that big w-cooling setup really helps with some of the benchies (never mind work+play apps) on CPU and GPU. Below is a Unigine Superposition 4K run for the 3950X/6900XT half of Raven_A - 1.218v on the GPU and ~ 450 W custom vbios were good for up to 2860 MHz , while GPU and VRAM temps with 23 C ambient hovered in the low 40s C and Hotspot in the high 50s C / low 60s C. The 5950X/3090 Strix half can still score a lot higher than that in Superposition 4K, but the 6900XT combo is catching up fast - and 4K is not really its best side... ...may be that's why Homer carries the deed for the house around

One thing to keep in mind w/ both antifreeze and slush build-up are the o-rings in your block (and perhaps even the materials of your soft tubing). Some types of anti-freeze can erode those, albeit slowly, over time. I remember reading that a certain type of Rain-X ('rust colour') is safe for this kind of thing, but can't find the reference to it right now. Also be careful with slush ('ice') as the sharp bits can actually strip nickel coating etc. inside blocks / micro-fins, never mind cause localized heat soak via blockage.

...the latest crop of CPUs (and even GPUs) are already very 'factory-oc'ed' anyway via boost algorithms, PBO and the like - I'm not in Kansas anymore... ...the best you can do for normal multi-use system for work, play and bench is 'go overboard' on custom cooling as temps are a major algo input parameter, and also play with Power Limit envelopes. 'The factory' however has already exploited a lot of the slack you used to be able to extract within old-school o'cing. It's still somewhat different for sub-zero but it is probably quite hard to play Crysis for hours while topping up LN2 in the CPU and GPU pots w/o causing a cold-bug
