I expanded the size range of FFT's I was testing with. I believe the "out of the box" defaults for the versions of prime95 and CoreCycler I was using don't trigger the peak boost frequencies the CPU can try to hit under the right circumstances. My current understanding is that CoreCycler in SSE mode with runtime set to "auto" and FFT size set to "all" will find instabilities that the defaults won't. Obviously, AVX and AVX2 would also need to be tested, but my CPU core 1 will fail CoreCyler within 5 minutes at an FFT of between 20k-1000K without any DOCP or PBO.

I recognize those latching LED push buttons on the front case IO panel. They are handy little dudes. I've used those (and some relays) to add custom flood lights to a lot of zero turn mowers.

After chasing my tail for a bit, I've reached the conclusion that its RMA time. I got a fair amount of guidance from OFFICIAL 5900X and 5950X two chiplet Zen 3 CPUs Overclocking thread | Page 64 | Overclock.net (from post # 1197 onward) on what to test and how. Will have more to add here once I'm back up and running again .

With color coordinated RAM no less .

I have been making purchases from Newegg for about 15 years. I turned the other cheek when they enabled 3rd party resellers. This has convinced me to avoid them if at all possible. Being more informed than myself, I'm guessing many of you had already dropped them like a molten radioactive ingot, but I thought there might be a few who still had faith in the egg.

When things like that happen to me, I always imagine myself morphing in "Jules Winnfield" and asking the negligent party "English mother fucker, do you speak it?".

Just reading the words "Enter Sandman" will have that song playing in my head all day

Update. CoreCycler seems to be the consensus tool for verifying Curve Optimizer settings on the Ryzen 5000 platform. As such, I have made frequent use of it to date. However, CoreCycler appears to indicate I have "out of the box" instabilities. I have previously checked the RAM installed in the system (2 DIMM's only, 32GB total) using 10 cycles of Testmem5 ([email protected]) and OCCT (6 hours) with DOCP both enabled and disabled. I have never had either program indicate a memory error. If I clear CMOS and start from scratch, I get the results detailed below. CMOS reset settings.txt

@firedfly Roger, if you had by chance signed up for both I thought the previous might be of benefit to you.

@firedfly Out of curiosity, was the "Black Gaming" available? I ask because numerous TechTubers were supplied with the $249 version of the card running the $330 VBIOS...

The retail price if you don't mind my asking?

The "analog" gauges did make my heart flutter.

I got in the bedroom. I got it in the hall. I got it on my finger, and I slung it on the wall.

However, I see you are aware of at least one of those threads already...

Here are a few more. Asus Crosshair VIII DARK Hero.... Official Thread!? | Overclock.net CoreCycler - tool for testing Curve Optimizer settings | Overclock.net [Official] AMD Ryzen DDR4 24/7 Memory Stability Thread | Overclock.net I'm still in the process of reading through them. I've never actually reached the end of any of them, and I've reread portions of them many many times...

I've never been comfortable with an open frame chassis for a daily driver. I'm too <cluck cluck>.

Before initiating last night's session, I opted to reinstall 64GB of RAM. Not stopping right there setting the BIOS back to defaults and verifying the stability of both RAM and the system in general before proceeding one tweak at a time was a noobish naive numbskulled mistake. Because now I have no way of knowing what particular change resulted in the never-ending series of errors testing exposed. So, no charts with conditions and results today. Tonight, its back to square one, after I tattoo "patience, grasshoppah" on my forehead .

Thank you for the feedback . As a journeyman PC "assembler" / novice PC OC'er, I don't intend to touch the BCLK at this time. If last night's testing (detailed in a subsequent post to this thread) showed me anything, it showed me how truly daunting a task it's going to be to improve upon AMD/ASUS's "out of the box" optimizations. It's relatively easy to "twist knobs" and improve a given benchmark. Getting the system to pass a "comprehensive" set of stability tests afterwards is more challenging in the extreme. This is all just for "shits and giggles". I don't need the machine to perform at even half of its default capacity. If I wish to enjoy this "journey" long term, I'm going to have to train myself to ignore the desire to immediately "win". My current goal, beyond having fun and learning more about what's "behind the curtain" of the myriad of BIOS settings" is the best "stable" OC I can achieve. For me, "stable" implies it passes not just benchmarks, but the worst-case scenarios tools like Corecycler can throw at it. I am beginning to suspect that my gains, if any, are going to be minimal, but that is logical. The default optimizations were formulated by people who do this for a living. They aren't Olympian gods with mythical powers, and they may have left some crumbs under the table, but can a rat like me find them? For myself, I think stamina is possibly the most important factor in determining how that question gets answered. Thinking about it just now, this is just a "gaming computer" and I have decided, for the time being, that I want to play "Benchmarkz IV, Fool's Errand" .

Okay, but how do you REALLY feel?

I have posted this same picture in my "build log". Apologies for reusing it here, but the temptation to "flex" my DCM Time Window 1a's has gotten the better of me. There's a Polk Audio center and two surrounds also in the frame. The sub (under the desk and occluded by the chair) is a generic Klipsch R-100SW 10". The receiver is a YAMAHA RX-V4A. Though my only source of pride in the whole setup are the Time Windows. P.S. Well, correction. I am proud of my daughter as well, but that framed picture of her is actually there to hide some cabling .

Interesting (also, sorry for the loss). If you are ever able to pinpoint exactly what failed on the SSD, I would be eager to learn of it.

Forgive my ignorance. Just to make sure I understand fully, the disk will be useable again after being "wiped", or it is FUBAR in perpetuity?

Based on last night's testing, I expect my peak stable single core performance to top out around 5000-5025Mhz. I was seeing around 5050Mhz in effective clocks with no observed clock stretching, but I will likely need to go less negative on the offset for true stability, and this will bring the Mhz down some. I tried some other settings not included in the table. A Boost Override setting of +200 with a positive CO of 30 limited the actual boost to around 4650Mhz. So, I have the impression that one wants the CO offset as negative as possible, and the BO set low enough to prevent clock stretching and maintain stability. I've debated installing Ryzen Master to speed up the process but concerns over what might install alongside it have prevented me from doing so to date. If anyone has suggestions/guidance regarding PPT/TDC/EDC, voltages for the static OC, best way to calculate Dynamic OC switch point, CPPC on vs CPPC off, or anything else, I'm all ears . My impression is that the rabbit hole's width increases in proportion to its depth
