...spent all that time optimizing my 3950X, but 'had an offer I couldn't refuse'. this afternoon. 5950X and ASUS ROG Crosshair VIII Dark not only actually available, but at a great price from the place we buy a lot of commercial computer equipment from...now I'm wondering whether to keep the regular Crosshair VIII Hero wi-fi / 3950X for other related duties, or sell it...

Thermalright are very good...make sure you know the right size, though. 0.5mm, 1.0 mm, 1.5mm etc. I got my Thermalright Odyssey pads from Amazon

...well, the latest Arctic P pwm series are a bit like a virus that can get in your head ? ...as suggested before, I tried out a couple for a few months before "going all in". I didn't want any RGB fans (there's enough RGB already, plus all these are push/pull - don't even see the ones on the back). ...I find they are ideal in push / pull to replace my GentleTyphoon (3K) and Sunon (5K)...even with big triple row, 480X64mm rads. On top of great cooling performance, they are also quiet (though everything is rubber-mounted). At 1.8K rpm for the P12s, all I hear is the 'whoosh' from the air rushing through, not the fan blades sounding like Cessna propeller. ...GTs and Sunon are destined for another project that isn't within immediate ear-shot

...yeah, according to this handy Samsung 'B-die' finder > here, you're right ...dual rank has advantages and disadvantages, but overall great choice RAM. The first thing I would try is switch to CmdRate 1T from 2T, even at a lower speed, say 3400MHz or 3600MHz, and less 'max tight' timings. You can then iterate your speed up and tighten timings afterwards. One thing to keep in mind is all the testing you have to do in-between changing RAM timings - some of them are interrelated, but generally, it is best to change one thing at a time - that way, you don't end up with 'one equation with 27 unknowns'. ...another tip: check > this out ...I realize it is for Ryzen, but it will still help as at least rough guidance for Intel. Apart from my Intel machines, I run a X399/2950X and X570/3950X...both have identical 'Intel marketed' 4x8GB B-die kits, yet the linked software was great for double-checking once I finished my own optimizations...the only thing I would disagree on is tRAS (per above post) but that's a minor thing. I even use that Ryzen DRAM calculator to check my settings for Intel Skylake. It will provide a great template to get you going into the rabbit hole, even if some Intel-specific values might differ slightly... ...final tip: Once you have made progress with your RAM optimization but feel there's more to be had, save 'intermediate' profiles in the Bios - you can always return to those and build on them for the next iteration...

...haha - way too small to serve as a pulpit for moi ? ...it's a laptop 'desk' from Walmart...has adjustable height and wheels for moving around a heavy build. For that, I used steel straps to reinforce the two top plate bits, and added a steel leg on the other side. Cooling system on the bottom (suspended by steel straps, rubber mounted), testbench frame on top with computer components....have custom clear and painted acrylic bits in process for dust protection / air-flow management.

...'from Russia Walmart with love' / ghetto build, ahem, foundation...

RAM optimization is a rabbit hole that is fun falling into, but frustrating to crawl out of...

Let's see if your Fujipoly can beat mustard ?

...what is your RAM vendor and model number, ie. GSkill F4-3866C18-8GTZR ? As you stated, I think RAM is indeed a good place to start in your quest for smooth and low frametimes, but at the end of the day, it will be a combination of that and other parameters, such as GPU settings. Your Radeon 6800XT GPU having a nice 16GB is a good thing, also.

...on the resizable_BAR, apart from my own timetable, I'm also waiting for a a final mobo bios update (currently only in beta). Re. your primary memory settings, if you feel like it (but no guarantees...), you might want to try 15-15-15-32-374 . I'm pretty certain about the 32 for tRAS with the other primary settings you showed as tRAS is best set as the sum of the first two (CL and tRCD) PLUS add '2'. The tRFC at 374 might work, but you can always play around with it...and before tRFC changes, have you tried command rate at 1T instead of 2T ? That usually provides a nice boost, even with GPU

One thing I can add to the list as a 'sub-theme' is certain memory timings on the main system RAM, specifically tFAW and perhaps tRAS. If tFAW is too tight - even with passing all memory stress tests, you can experience some serious stutter. Another development to keep an eye on re. frame times is the release of resizable-BAR. I'm tied into knots right now re. time, but hope to test that out later next week on my 3090.

...you should talk to DerBauer...back in 2017 (+ before, + after), DerBauer had some fun with Novec... I remember him using it on a dual Epyc, but he obviously went on from there... I understand from people who have used Novec that air-borne particles / pollution can make it potentially conductive, so no eating salty french fries near-by. If you want to get really serious, you can ask Kingpin for his "closed-loop" LN2 system...those actually do exist in real life. D-Wave Systems (Quantum Computing) which is about 20 min from our place uses s.th. approximating a closed-loop LN2 cooling system

...probably psychosomatic, but the FS2020 Microsoft Azure server for my region is at that location per latency info and lately, it feels faster ?

Tx. I edited the OP...It's still in the middle of working hours here (Pac time zone)....will email you later

...just delete the thread, please. Tx.

Gesundheit for the cough ! Not clear what to do here if you look at my OP...over half is not Anandtech but refers to several other articles I read but can't find the source for " ....that part is not particular to the article below, but nonetheless interesting. There is also the assumption that NVidia with its high-powered (but mostly non-obtanium) GPUs is interested in adding more general RISC to its future repertoire...worth keeping an eye on ARM and RISC..." May be just delete that thread ? Tx

banned coz...Brigitte Bardot Beret

...one day we will all wake up to the fact that @iamjanco was actually building an extinction-level super bang thing...

...more shiny things ?

...if x86 (and with it games/sims/entertainment) can somehow be more than approximated, the expected 'convergence' with RISC and x86 would be truly underway....don't have a source handy, but I read somewhere that Intel and AMD are working on mCPUs with 'differential' tiles to accomplish this. Hope springs eternal...

...yeah, AMD seems to handle the communication abut this well. FYI, apparently, Phoronix is planning a performance impact analysis of certain bits in the affected predictive branches being turned off, or at least 'nerfed'...

...long Easter weekend allows for extended flying...from Russia with a slow amphibious plane to exceeding speed safety limits flying low in a valley in the Himalayas ?
