"few very unique CPUs" AFAIK, you were around (in the enthusiast community) when AMD64 stormed the market. How can you say this when, the entirety of S754, S940, and S939 processors lack compatibility? Your experience is missing details. This isn't a case of "Well XYZ product always worked great for me". This is a case of hard facts, showing an entire era of revolutionary CPUs is hardware incompatible. This isn't a "rare, unique" or "anecdotal" issue. x86/32-bit Windows is not a viable substitute. Unironically, running some lightweight x64 Linux distro + Steam with compatibility layers is the 'best' solution @TM, and you lose a lot performance to 'overhead', esp. on older hardware.

As I linked, mentioned, and expounded on here: CMPXCHG16B / CompareExchange128 is a Windows 8.1 x64-Onwards requirement. (and was not present on AMD CPUs until the AM2/K8+DDR2 era) It has little to do w/ 64-bit, other than MSFT req. support for it in 8.1x64 and newer released. AFAIK, Intel has had support for CMPXCHG16B / CompareExchange128 since the very first EM64T Pentium 4s. Similarly, AMD K7 lacks even more instructions vs. Intel's contemporaries. K7 (Athlon 7/XP/MP) is early-P4 fast but limited in software support to Pentium 2-3 era sofware.

That's an AM2 Athlon 64 X2 CPU which, does support CMPXCHG16B / CompareExchange128 AMD Athlon 64 X2 6000+ Specs | TechPowerUp CPU Database WWW.TECHPOWERUP.COM Windsor, 2 Cores, 2 Threads, 3 GHz, 125 W AM2 Windsor(onwards) core K8-uArch, has the instructions.

That 4GiB memory limit is a real PITA. Not to mention, Windows 11-forward is depreciating 32-bit Install support. Also, non-64-bit Execs are typically limited to 2GB RAM. (There's more than a couple games over the years I'd had to edit the exe on to not run out of RAM). More info: Windows 10 64-bit requirements: Does my CPU support CMPXCHG16b, PrefetchW and LAHF/SAHF? SUPERUSER.COM I'm currently trying to find out whether or not it would be a good idea to update my slightly dated notebook (Windows 7, 64-bit) to Windows 10. The problem is that Microsoft states in their Windows... What is wrong with this emulation of CMPXCHG16B instruction? STACKOVERFLOW.COM I'm trying to run a binary program that uses CMPXCHG16B instruction at one place, unfortunately my Athlon 64 X2 3800+ doesn't support it. Which is great, because I see it as a programming challenge...

Don't freak out, or start tearing it apart. I've had multiple Vega cards *act* like they've bricked themselves. (WARNING: this is 'bad advice') What's fixed it for me, is yanking mains power to the sys mid/just-post POST. Next reboot, card's back. Has happened a dozen+ times w/ both my real deal Vega 64 and my MI25s-turned-WX9100. (even my 6500XT has 'played a similar game')

I think Chris was on the right track w/ the 3.3V thing. AFAIK the 3.3V rail on Video cards is used to more-less 'handshake'. I'm not quite familiar enough with the electronics on the PCB, but I'm suspecting the manu. neglected a 3.3V voltage converter on the riser. If you can, try plugging in an ATX PSU into the ATX input on the riser. (Some also run their 3.3V power from a +5V source using a linear regulator. Try hooking the +5V input on the Riser to +5V or a USB's +5V?) This might be (related to) the issue, too. PERST# info: AMD Customer Community SUPPORT.XILINX.COM

Terminator 2: Judgement Day Why? Arhghuhnuld w/ a mini-gun, ofc. Oh, The story and effects are bretty gud too

If it wasn't for the overspray, it'd look like you just turned the gamma up on the on the same pic. Looks great! Now...

99% agreed. the 1%: I can kinda 'see' being upset @ the base-packaging. Though, depending on marketing/pricing, I can also see the vendor/manu's PoV. That's probably the most affordable way to bulk-package them. IMO, the 'proper' way would be layered-in cheap molded-plastic trays, or cut-out closed-cell foam. However, doing so drastically affects the density and cost-efficiency of freight (at scale). TBQH, as long as every switch works, you're (typically) never seeing them (once keycapped)... Overall, I too would be very-appreciative of the community-collectable tin. Edit: I went ahead and actually read what this is all about. Seriously? The details in the reviews illicit a picture of a fairly well-ran operation yet, were used to support saying they were slow? IMO here, USPS is responsible for the lacking tracking, not The Vendor. I'd be giving benefit of the doubt, as I've had this kind of thing happen multiple times with multiple Vendors/Indiv.sellers. Note: This is also 'expected behavior' for semi-DropShipped purchases; actually coming from overseas on regular shipments and handed-off to USPS. Unless The Vendor was within (reasonable) driving distance, I don't see the problem. [Ex. I've "RMA'd" in-store w/ Monoprice in SoCal] Funny, I'm actually interested in purchasing from this vendor, 100% due to "attempted bad PR" (and I don't even need keyswitches... Tho, do they have metal keycaps? ) Edit 2: Oh, darn; no fullmetal keycaps. Only Keycaps they have listed: SwitchCaptain x SIKAKEYB - Cherry Forrest Keycaps WWW.SWITCHCAPTAIN.COM Green and white double-shot PBT keycaps featuring a cherry profile height with an increased spherical curve.

ESD damage is insidious. IIRC, ESD doesn't immediately 'kill' a lot of ICs, it 'erodes' and moves elements/ions @ the nano scale. TBH, I'd been wondering if +5V (pulsed/unfiltered) DC on the ground plane* (the HDMI 'dapter incident) damaged capacitors (or other components) from reverse polarity (and/or 'noisy') current. *Was it ever verified if the anomalous 5VDC was actually on ground, or was it just overriding the PSU's +12VDC? I've had a couple cheapie FP USB bays directly bridge +5VSB (motherboard-allocated to USB) to +5V; which, caused a similar symptom but, only on +5Vrail-connected devices. It might be worthwhile to further-investigate the suspected cause for the failure: the HDMI adapter. I know you have a DMM (somewhere).

The lack of PCIe x16 slots is deeply disappointing, however. At least you get: 3*PCIe x16 slots for Multi-GPU and 4*PCIe x4 M.2 slots. 'Not seeing if they're all SoC-connected, and Gen5. Though,the math says: "Yes; they're CPU-direct Gen5" Yeah... half the lanes (but double the bandwidth) is disappointing. I supposed it is further delineation of product lines (between TR7k and EPYC Genoa) Also, it's worth keeping in mind: -EPYC Genoa can only allocate 64 of its 128 Gen5 lanes for CXL use -This is officially TRX50. (Don't forget WRX80 was seperate and more-featured vs. TRX40.) -WRX90, is still to come:

Themesong? Wobbly Things...

IDK how to properly convey it but, this fan seems like the 'crosspoint' of many designs across other industries. -a 'no duh' design; one that no-one'd been willing to 'put together' for the consumer/enthusiast-facing market. Very attractive, both aesthetically, and technically. TBQH, this looks like the first 'axial blower' that I'd be willing to pay $20+ for. Any chance EHW might get some review samples?

IMO, just like 'cholesterol' in Heart Disease these amyloid proteins are tangential to the problem, not the cause. Glad to see there's now some research to back up that "uh, duh?" on my part.

Have you tried 3rd Party Drivers? Through several updates, I've had excellent luck with RdN.ID / AmernimeZone (NimeZ) drivers. On my Vega(s). RdN.ID @Sourceforge WHQL-AMD-Software-Hybrid-Edition-23.9.3 img/amernime_blue_thumbnail.jpg Amernime Zone - AMD 3rd Party Drivers WWW.AMERNIMEZONE.COM 3rd Party AMD GPU Drivers with Customizable Tweaks It'll also let you chose 'branding' and 'feature level' through the setup-configurator.

It's been my experience that the 'fall back' P-states, have to be customized too. AFAIK, these MI25s are the only Vega that *needs* tweaking beyond P6 and P7, for max Watt/Perf. I mean, it makes sense. We're basically 're-binning' Vega 10 16GB into another product line note: Samsung HBM2 seems to run 1+ghz no problem, even with a 1025-1050mv 'HBM voltage floor' set. I played STALKER: Anomaly for *hours* yesterday, sustaining 1390-1528Mhz core*, at less than 1100mv. 220ish-260ishW sustained, 280ish peak. If I push voltages to 1100mv or higher, I can get 1600+, but hotspot or HBM temps eventually cause instability. (Also, the 2-less power phases trying to push 300+W might be related. I've seen 350W+ pulled from my card, before overheating) *After using OverdriveNtool to 'find' stable clocks, I used RadeonWattman to create a profile for STALKER Anomaly that locks it in p-states 5-7 (some areas in the game don't 'load' the GPU, even though the clocks are needed for smooth framerates) Any idea on how to edit the vBIOS's clocks/voltages? I'm very close to finding my card's "sweet spot", would like to make it 'permanent'. PS: I've got a 6+8pin MI25, on the way; I'm very curious what the differences between the 2 MI25s are.

Wow, that's almost an impressively-low score from me. My Titan *was* watercooled; the original owner couldn't get it working, so I scored it CHEAP a few years ago. (he mis-mounted the waterblock, and shorted it. Thankfully, non-destructively). So, instead of a proper GTX Titan OG cooler, it has an eVGA Titan Black cooler on it. Which, required some 'gorilla mods' with a pair of pliers and a knife before mounting. Some of the pads/cold plate don't make PERFECT contact, so I didn't want to OC and push it. @pioneerisloud got me to try anyway, and she's not a good OCer with such meager cooling. Still, a nice card in my collection. HWbot ever do CrossfireX/SLI challenges? I've got 1GB G92s enough for 3+way SLI, and at least 2 working RX580s left hanging around.

Cool, Thank You No complaints. Just assumed I'd messed something up.

Did I miss something, or is the name a binary pun on an extension-expansion to AVX2? AVX AVX2 AVX-512 AVX10 ("2" in 'binary'?)

As a learning experience for me: What happened to my Titan run? I know I had to edit it due to a browser mishap re-populating my old sub's details.

New Fuzzy Donut!? Sweet.

Perhaps, you find the Latency acceptable, I do not. (Even, over a simple and modern LAN or WirelessLAN) I believe that's something of a sentiment shared by a portion of Retro-Console community, too. See: FPGA Retro Consoles You have a point, nonetheless. For those who either "don't know any better" and/or "cannot tell the difference", 'streaming' is an apparent, simple, and affordable solution. From my PoV (in researching eGPU's progress over the years), I'd say the biggest consumers of eGPU enclosures were professional artists, graphic designers/animators, CADworkers, and Pro media editors. That's a market, and one that can/will easily shell out $$$$. Note: Even for Pros, Amazon AWS (aka: streaming) allows a similar utility. Yet, I still think this is more a cost-availability (and publicity-marketing) thing: If no AIB/manufacturer is willing to make 'affordable' eGPU 'kits' (and advertise them), then it'll never become popular. Ex: Many (Apple) users cannot even conceive of upgrading their machine without just buying a whole new one. Why would they think 'plugging in an upgrade' would be possible? IMO, Intel's just trying to stir-up attention on ThunderBolt 5, and their License(d) Partners' "Features and Abilities". Sadly, Thunderbolt has almost always been relegated to 'premium' offerings. Rarely, if ever will you've found Thunderbolt on a Sub-$800 (MSRP) laptop. To me, Intel's attempt @ PR here is entirely self-defeating. -Advertise something that will only become popular if affordable -Yet, relegate that "advertised feature set" to only premium units. Edit: I just used USB4 on an AMD Ryzen laptop and it's amazing! | PCWorld WWW.PCWORLD.COM Not gonna lie, I legit got giddy plugging a Thunderbolt device into an AMD-based laptop with real USB4 support. USB4 Systems PCIe Tunneling Support | Microsoft Learn LEARN.MICROSOFT.COM Verifies that systems support PCIe tunneling on all exposed USB4 ports.

Your simplification-explanation, belies and describes the precise reason I'd mis-lead myself: Duty Cycle % would also fit that definition. Any magnetic or resistive load cannot exceed 100% Duty Cycle. -Regardless of its rated rotational speed, torque, or thermal dissipation. Honestly, I just didn't think 'it was that "dumb" '. Makes a lot more sense to me to be a duty cycle (to me) but, I can see the utility in it being simply compared to the known-equipment's RPM rating. Ex: if your card is 'stock' and the fan % is low, that'd be a sign the bearings are failing, there's air-restriction, or dust has built up on the fan (slowing it). Edit: Incorrect. Replacement is also a 4-pin PWM fan, pin-for-pin adapted to the GPU's fan header. Also (AFAIK), RPM is off a 'pulse signal' from a hall-effect sensor/equivalent* in the fan. (*IIRC, 'back EMF' can be used as a sorta in-situ hall-effect sensor.)

Being PWM, I was worrying about the "Fan Speed %" being derived from "PWM Duty Cycle" rather than a comparator to a 'fixed, expectant value' in vBIOS/PPT. One of those times where 'other experience' can mis-lead one away from the answer Like part numbers on Brake Calipers, they're *not* unique for each side.... Now I we know.
