Hi E - Even if it is understandable, it is still a big loss for us here. Thank you for all you have done at Extremehw.net, and best wishes as you travel past the second star on the right and straight on till 'morning' - J7

To answer your original post, there are very few differences between 670E and 870E. Technically, the only 'mandatory' difference per AMD is that the 870E series must have USB4 (psst, Thunderbolt) as standard, while it was optional on the 670E. Then again, you can get a nice 670E and put in an AIC for additional options. Most of my mobos (total ~ 20) are Asus ROG desktop and/or HEDT boards, with the odd Gigabyte and MSI. That said, I picked up an Aorus 670E Master last fall along with a 7950X3D and 2x 24 GB DDR5. That board turned out to be a fantastic performer...DDR5 8000 and beyond is no problem (have run at least 8000 since I completed the build). The system also has a no-sweat profile for 4x 24 / 96 GB CL30 6400 that works perfectly well when I ran it for a special LLM task. BTW, I had my 670E Master as high as DDR5 8600 with 2x 24 GB (via bclk, though)...great board for RAM oc. I am waiting to see what the Ryzen 9950X3D is like in real-world testing - I will either add another Aorus 670E Master or pick up an Aorus 870E Master if I go for a 9950X3D instead of another option such as Threadripper Pro. The Aorus 670E Master and 870E Master are almost identical other than the faster network chip. The Aorus top boards like the 670E/870E Master also are among the few boards that can run R-DDR5 (full EEC memory) without any issue, and they also have bifurcation options - both are important to me as I tend to recycle my fun boards into productivity tasks down the line. I should mention that there is also the Aorus 870E Extreme coming out - it is like the Master (both support DDR5 OC to 8600), but the Aorus 870E Xtreme also has dual 10 GBE onboard and some other extras such as programmable LCD screens on the mobo. The only problem: It likely will be around $800 - $1k So for me, the Aorus 670E/870E Master are the best choice, but the vid below has detailed a 21 board feature comparison review for 870/870E - a great reference piece.

...top: older shot of F18 (Microsoft FS and AeroFly). Lower pic: Microsoft FS and Cyberpunk 2077 / PLU with updated system RAM tuning that yields Benchmate Y_Cruncher Pi-1B at 12.783 s. With r_BAR on the 4090, this works better than ever before; absolutely smooth, high fps, low 1% and 'no waiting'

Definitely looking forward to MSFS 2024 - hopefully, it will not have as many teething problems as the initial-release MSFS 2020 had...that plus the hope that one can upgrade from MSFS 2020 > 2024 as I have a lot of locally saved scenes

Compared to above, this is 'only' 4K60 HDR Dolby Vision but very nice scenes and great for OLED

As posted elsewhere, updated game settings for my favs: MSFS 2020 and CP 2077 U/PL...MSFS 2024 coming in November with 'ideal system specs' that include 64 GB of RAM...

Full-blast game settings with updated memory profile; r_BAR forced on, HyperV w/core isolation; Win 11 Pro 24H2

It will be interesting to see what the custom PCB vendors will be allowed to get away with in terms of PL for 5090s...many custom 4090s are already above 660W. Hopefully, the 5090s come with 'better' ATX 3.x power connectors (preferably two for the top cards). I have had my 4090 for almost two years and the 7950X3D for just over a year now - I like to build something new but would need to be convinced of the value in terms of extra performance. While I already have CL34 8000 48 GB (below) and also a functional CL30 6400 96 GB profile, MSFS 2024 (release November 19th) has an 'ideal spec' of 64 GB

...no idea because I do not know your board, or the specific chip quality. I used the Skatterbenecher video I showed above to set up my first 'eclk'.

...and sneaking up on an A320 near Anchorage (real traffic in MSFS 2020) 4K png

Depends on your board (some do not have eclk). On the Aorus 670E Master see the pic below with the arrow > switch to 'enabled' from 'disabled', after booting back in with 'default bios values'...always do that extra step before going back and forth between enabling and disabling that one. Re. memory, I do not own a single piece of EXPO RAM over four gens of AMD; I just always use Intel XMP and/or do manual values. However, EXPO or no EXPO will not make a difference with eclk (it leaves FCLK and the memory setting as is).

...didn't know there were 12K 240 fps monitors out there...how many 5090s does that take ?

Tour de Skagway...

'Tour de Skagway' to check on PTM7950 hotspot deltas for the 4090 and 7950X3D blocks; zero deviation from months ago

This is what I used for my first eclk (see timestamp YT). Make sure though to load 'default values' anytime you go / to from synchronous to asynchronous in the bios / tweaker menu

...at least the early (1.10 V max) custom 4090s had a 450 W base and 600 W oc bios right form the factory (same for the founders edition)...even with that one and plenty of cooling, my stock Giga-G-OC vbios would have transient spikes of 670 W+. I actually run the Galax HoF vbios (~670W before spikes) since November '22 on it, and also have (but only tested gingerly) the Asus XOC 1000 W bios. At the end of the day though, the 4090 is so powerful that I actually restrict the power budget to 90% (out of a possible 122 %). Custom 5090s likely use the same base-PCB as the custom 4090s, perhaps with some upgraded components. The same power on a smaller node with architectural improvements and GDDR7 should yield plenty of additional performance...cooling the hotspots (which have input to the boost algorithm) will be paramount for good sustained performance

I have the PBO enhancement at 90L5 for all profiles and clocks (system has good custom water-cooling)

1.) Are you sure you are doing 'bclk' instead of 'eclk' ? 2.) With bclk, your PCIe 4.0 GPU (and perhaps NVME drives) will likely not post. PCIe 3.0 setting / older GPUs might. Try 102.75 and see what happens. With eclk on most Aorus boards, the RAM and PCI bus will stay at 100 and thus not be affected, only the CPU. 3.) Make sure to disable all CO and also disable boost override and try 102.75. You might even have to go into negative boost override, depending how far you push the extra MHz. For example, if you know that your 7950X/3D can hit max effective 5750 MHz, multiply that by 102.75 and subtract 5750. The resulting number should be a safe negative boost override from which you can experiment. Leave CO disabled until you have the boost override 'safe' value locked in and tested.

...three months to the day now with the Beemer PHEV. The usable battery range keeps on going up...that said, the prices for gas are going down - PHEV = win-win ?

This 8K Dolby Vision one is ~ 6 month old, but there are some really stunning scenes in there...

...several places, including this...

An update on the recent X3 PHEV addition....just over 3K km on the odometer now since getting it new mid-May. Properly warming the engine up and using mostly the gas option for one way of a roundtrip while going back the other way completely on electric power works very well, also re. milage (> 43 mpg / US). I also switch to electric when in stop-and-go traffic on certain stretches but mostly divide their workload into the aforementioned trip segments...much calmer and less wear on the engine, starter and such, IMO. Most of the driver aids are turned off, and I do like to have the touchscreen for various things but augmented by real 'analog' volume buttons for the sound system (the same for climate controls) It is a bit strange but welcome when on 'electric only' to feel the gear changes as the electric motor is integrated into the transmission. Switching it to xtraboost (gas and electric power combining) is a fun thing to do on a curve mountain road Even without the electric boost, the turbo-4 is very torquey

...cutting free fruit ? That's going too far

I see more and more folks trying to sell their 14900K systems now with sizable discounts, sometimes with Z790 mobo, RAM - the whole lot. Intel also announced suspension of dividends and the potential for job cuts after 'not meeting sales expectations' this quarter. I still have more Intel CPUs than AMD, but my last four purchases were all AMD 16c/32t of different gens (got the first one in November 2018). I hope Intel finds its way through this and AMD stays 'humble' since we as consumers benefit from real competition. Below is Intel's ytd stock price - ouch. This comes at a time when Intel is trying to grow in the discreet GPU market (say hi to NVidia at the top and AMD in the middle), defend their server / enterprise share and expand building new fabs....those fabs take many billions of $s capital cost upfront and three++ years before any return on investment - and a hidden flaw can ruin the best-laid plans. In my humble opinion (I may be wrong), Intel's root problems started with their last CEO, a time when Intel was not led by someone with a decent/any engineering background.
