...'one for the road'

....new LGA 1851 socket for Meteor Lake; making the 'when to update' game even a bit more tricky. AMD's new socket for Zen4 on the other hand is expected to stick around for a while, just like the current AMD desktop socket has... source

...re. voltages (top right in Zen timings), looks good...still, you might want to see if you can bring VDDG IOD to 1.0v, but not absolutely necessary. tRFC, tRFC2 & 4 could be lowered, ditto for primaries, but I think these are your 'stock' settings, before OC ?

...only two survivors here, both running happily with AIOs these days; the rest were put in systems donated for special needs

Banning EVGA...I was in their email system because I had purchased a lot of 'Classified' cards up to 2015, but since then switched to other brands. After years of silence, these days, EVGA has gone mad with email ads re. their inventory glut ...I could unsubscribe (may just do that), but I like to stay informed about 4090 KPE and big PSUs.

...76 C is ok, but it also depends on ambient. Re. Zen Timings, it also contains a nice summary re. IMC related voltages, some of which are quite important. For 'later', this video by Derbauer is quite good re. the Dynamic OC feature with the CH8 Dark Hero mobo, noting that he has fMax enabled which it actually shouldn't be for Ryzen 5K (it is great though for Ryzen 3k)

Looking good ! ...sorry, just stick with the term 'PBO'. I sometimes use the '/2' solely because I run a 2950X, 3950X and 5950X and there differences in the PBO versions. ...CinebenchR23 was released before Windows 11, so it calls it Windows 10 (build 22000). ...can you add a ZenTimings screenshot ? Looking not only for timing but voltages (ie. around SoC) When all this is done (looks like you're well on your way!), then you can also explore DynamicOC, and option that sets the Dark Hero board apart, as well as Curve Optimizer.

There are tons of tuning options for Ryzen, but the main steps are fairly simple...set your XMP/DOCP in Extreme Tweaker bios page, enable PBO/2, noting that unlike many folks, I leave the PPT/EDC/TDC values on auto....fMax enhancer should also stay on auto (as in 'not enabled') for Ryzen 5000 series. In addition, I run a small undervolt at -0.00625V. LLC is also on auto. Once PBO is engaged and everything is working, you can return to the DRAM settings and use the earlier-referenced Ryzen DRAM calculator to tighten your timings (lots of testing !). There are a few other steps after that, such as Curve Optimizer you can look at later, but I would first work towards the above with full stability. This > thread has been very helpful when I set my 3950X and 5950X up. Once you reached the above with stability, please post a Zen Timings screenshot, along with HWInfo open during Cinebench R23.

...I think you have built a gorgeous - not to mention powerful- system....flowmeter or no flowmeter.

...watch how I get myself in trouble here... If you have some tubing left over, I would just leave out the 'flowmeter' completely...personally, I think it is silly. You rarely if ever find one in the hi-po systems that run dual CPUs and 5+ 3090s and such for workstation+ apps. I've been building custom loops for a decade, including for commercial, and I rather hang myself than use a flowmeter. That said, I never use less than 2x D5s in a given loop circuit, but when starting out with a build, you establish a baseline on air. It should be immediately obvious if your subsequent w-cooling setup is not performing. Then again, if you want to add racing stripes to make your build go faster...

...some Cyberpunk 2077 at 4k ultra, psycho ray tracing, HDR 10 pro (which screws up screenies even more, but sure looks good on OLED) ...and some FS 2020... ...and with the newly available 'Halo' Pelican

...agree - mine isn't even connected, but HWInfo makes me feel good as it says 1.112 million liters/hr. Anyway, I always knew I build really hi-po loops

FYI, once you fixed the mount re. flow direction, recent/the latest HWInfo have a segment for coolant flow...question is how accurate.

...time to oc, bench and game !

...tuning RAM can be a dark art, but it is worth it for Ryzen as it reacts really well to it re. fps etc. A MUST HAVE is > this if you're new to it in the Ryzen RAM context - just plug in your RAM specs and select 'safe' or' fast'...this is of course after you turned PBO/2 on but leave values on default. Also, the DynamicOC option in CH8 DarkH is great but should come later / after everything else has been made 'max stable'.

...more complex now - especially w/ all the AMD tuning options - than w/ 4790K, but a ton of fun, really. First decision: What bios to run (I use 3801 for Win11 CH8 DarkH). If that bios gives you no troubles re. USB etc, keep it. Next, max RAM speed / timing. Once those are settled, feel free to ask for advice...

Enjoying some FS 2020 flying (Vancouver, Mt. Cook area New Zealand)

Wow - that was significant contamination ! Ed.: ...but once you're done, max your 5900X, pick a medium level oc for the 3080 Ti for FS2020 and go flying in the New Zealand mountains for some reward !

It's good that MMM is stepping up, but still, there's the time lost (never mind disappointment), and the disassembly and reassembly....

...if the gas station earns a percentage, higher prices (at the same percentage) still means more mulla in their pocket - but yeah, meantime, many oil companies have reported a tripling of their profit now...

...would be nice to own that gas station, too

Q - What is green, orange and dusty-gray with a pinch of salt ? A - spring time in BC, dashboard, dirty engine bay courtesy of Canadian winter driving

This must be very frrrrrustrating ! Instead of tuning, oc'ing and playing some games, it's back to loop cleaning...but hang in there - it's a gorgeous build and soon all this little setback will be forgotten. For the two Ravens' Nests builds and their expansive cooling volume, I had picked up one of these (below, 'a bucket for monsieur') but 'cut it' with 30% deionized water...almost a year later, everything is still pristine, per acrylic view windows on CPUs and GPUs. Next time around, I'll likely just go for pure deionized water with some antifungal / anticorrosive drops.

Bummer...I would just pick up some gallons of deionized / distilled water and flush the system thoroughly...afterwards, you can use a fresh fill of deionized / distilled water and run it for several weeks in your setup as is - but eventually, add the appropriate amount (a few drops, depends on loop volume) of antifungal & anti-corrosive additive (ie. XSPC etc).
