Yes, but the companies think from a cost/business perspective.
They can probably produce 12nm controllers for 20% cheaper (or more). They will always lag the leading process tech by a few generations because of this.
The fact that Phison is fabless, and a smaller company, also mean they'll...
Ok. I'm not the best person to dive into the highly technical aspects of the Intel platform, but another factor to consider is the benchmark itself. A single core/thread might not be able to use all that bandwidth effectively, if you threaded all the benchmark functions to run an instance on...
It is possible that the fact that they are not identical is the cause.
How many ranks does each dimm have ?
The mem controller will split the accesses between memory channels and ranks. If one dimm is dual rank and the other single rank, the memory controller might not be making optimal use of...
I've had 4 gigabyte boards since my favorite board maker Abit went out of business.
One of them failed, but to be fair it was a budget board and I think a faulty psu caused it (gigabyte still replaced/repaired it).
The other ones were highend boards and were rock solid.
I've also had Asus, msi...

Try playing with you bios settings.
Disable "quick post" or similar. Some bios have a delay in seconds you can set.
If you are still unable to fix the issue i'd suggest contacting customer support for your motherboard and/or toshiba.
Does you bios have a boot override list ? is it detected...
You might be missing another SMD component next to where "4" is written on the pcb.
That pad looks like it had something there ?
Check the floor before you vaccum :)
If you have a soldering iron, and some patience, you can likely replace the entire connector.
Sometimes ebay has salvaged pcb's for cheap too, if you can find the exact part number (might not work).
Chances are the read/write heads were parked when it dropped and they weren't broken.
The pcb on the drive can be replaced, if the sata connector cannot be resoldered/replaced.
There are several companies that can do this, but it can require a specific revision and bios version be matched to...
Don't feel bad, a lot of people are struggling with PBO and CO. They are much harder to get fully stable than your typical review might suggest(and take a lot of time). Countless threads have people saying "no errors" ... then they reply a few days later saying they came back.
Another thing to consider is that the warranty is 3yrs, so you have plenty of time to try to get everything working :)
BTW I just upped my VDDP (PHY) voltage a little and my errors seem to have gone away. (EDIT: Error came back).
Just like you, 1 day, or even 1 week might not be enough to...
Also, to clarify, AMD considers PBO a form of overclocking and don't guarantee it'll work (it voids warranty if you admit it).
Chances are that you will have to adjust other voltages/settings to get PBO stable, which can take more time than most anything.
Personally, i'd rather know what the issue was with some certainty before doing a RMA.
I read a reddit post where the guy returned his CPU for RMA and the new one gave the exact same MCE error.
It can be time consuming, but really all we can do is try eliminating the components one by one to...
I suggest disabling PBO2 and curve optimizer (officially not supported/guaranteed to work). Use AMD officially supported settings (AUTO or NORMAL) for most other settings and try to rule out a defective cpu.
Although "officially" supported is kinda hard to pinpoint with an automatically...
To be honest here, i'm having similar problems with my 5950x.
It's producing MCE errors every 6hrs+ or so.
I keep adjust voltages and retrying for the past 2 weeks, they won't go away.
My error messages are slightly different than yours however:
ras-mc-ctl --errors |tail
137 2022-04-13 07:38:43...
Yes, MCE is machine check exception. Not "memory" check exception.
It could just as likely be any component of the cpu which could include the UMC, IF (IOD and/or CCD), cache, etc.
Really, the error is not descriptive enough to be certain of anything. But the fact that you have modified some cpu...
I think the only real solution to this would be an AMD sponsored bootable image that is able to cycle all possible core/mhz/voltage combinations like memtest. PBO is perpetually unstable for pretty much anyone who uses it. You can't trust something that can't be tested.
If I can save up some $...
One thing that really bothers me is that it's impossible to validate stability when using PBO and curve offsets.
Infact I was just editing a text file and the system just rebooted ... after hours with no issues, no mce errors, etc.
You just can't force cores into their multiple voltage/mhz...
I was also speculating on why some cores just refuse to boost nomatter what bios settings you use, and i've come to the conclusion that AMD is using some kinda quality ranking internally for each core.
IE hypothetical equation:
f(x) = Vmax * (1 - Q) ^ (F - S)
Vmax = max available vcore(ie...
I recently modified my linux kernel to use custom CPPC numbers for each core, and use intel's preferred core scheduler code because AMD hasn't implemented that yet.
I wrote a program to stress each core with affinity and measure MHz and power usage and generate my own CPPC numbers.
The factory...
It's amazing that no pictures online show the actual ordering.
I know they can disable any core they want at the factory, influencing the ordering.
But I imagine it's not random.
Basically, what i'm wondering is if they order from top/bottom or right/left on the actual physical die. They could...
I'm using a -0.08125v Dynamic vcore offset, then optimized the curve from there.
Highest temps are in the 70's now, and 5GHz boost on all cores is pretty consistent.
+0 boost clock overrride. I have not bothered to try to find higher clocks yet.
My first CCD is also worse than my second CCD. The...
I was wondering what the correct ordering is for zen3 on the die.
I created this image to be what I think it might be:
Can anyone verify which is the correct ordering ?
IE: inside the bios curve offsets for core 0-15 will correspond to which cores.
Thanks
I think the lower 1 or 2 heatpipes are tasked with having to remove more of the heat than the rest. The front lower CCD is also strained more by the OS scheduler and gets worked the most compounding the issue.
Yes, I noticed that too when I was sanding. The heatsink base was convex and the IHS was concave. Now they are both about as smooth as I have the time to make them.
I think an offset would definitely help, but unfortunately the NH-D15 (non S) already basically touches the top of my video card...
I wouldn't use a thermal pad over liquid metal. Unless the pecking order has changed drastically.
Most all the reviews i've seen show all the dual tower aircoolers in the same ballback as my NH-D15.
It seems that I need to just be happy with what I have for awhile (except optimizing the...
I was getting frustrated with 90C temps on my new build.
After thinking about the heat density of these chips (one of the highest ever), I decided i'd give the IHS and heatsink base a sanding.
Nothing too crazy:
150grit -> 220grit -> 400grit(wet) -> 600grit(wet)
thermal grizzly conductonaut...
I think, ultimately, choices are limited by cost and complexity in this matter.
The soldered IHS is relatively simple/cheap.
An idea that crossed my mind was if the IHS wasn't flat, ie: channels this would increase the surface area. But such a "simple" thing would actually increase complexity...
I can't submit my results here:

They require windows software to verify it now. This wasn't the case with zen+.
But I don't see a single 4x32GB setup on there.
Yes, they have the same chips as non ecc ram, just 1 extra.
Ecc works and lets me know if an overclock/setting is unstable. I test till no ecc errors happen, even tho unstable settings could pass memtest and are corrected.
Ecc is great, like an early warning and safety net.
Also I put some...
