860 EVO 250GB causing freezes on AMD system

What OS are you using, Swift42? What driver (AMD or Microsoft)? Is that registry tweak still valid for Windows 10?

 

Thanks!

The best solution is:
Disable 860 EVO on AMD platforms

I'm sorry, but there is a better option if you cannot throw either the 860 or the AMD computer to the bin. In Windows 10, when using the default Microsoft SATA driver, create a text file with the following data and save it as .reg.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device]
"NcqDisabled"=dword:00000001
"SingleIO"=hex(7):2a,00,00,00,00,00

That will disable the NCQ in the Windows driver for all SATA controllers (you can do the same for your specific HW ID if you have several SATA controllers) and it will avoid the CRC SMART errors in the 860. It has been tested in an ASUS1215B laptop and it works perfectly.

 

If you prefer to install the AMD SATA driver (in Windows 10, also valid for Windows 7), do the same with this data:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\amd_sata\Parameters\Device]
"AmdSataQueueDepth"=dword:00000001
"AmdSataNCQDisabled"=dword:0000000f

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\amdsata\Parameters\Device]
"AmdSataQueueDepth"=dword:00000001
"AmdSataNCQDisabled"=dword:0000000f

I hope this helps many people with AMD controllers. I contacted Samsung technical support and they just disimissed me with no solution. I had to find out the different registry entries in the Microsoft driver and understand which one disabled the NCQ. Luckily, it was easy to find and test!

Siento discrepar sobre la calidad por ahora de mis dispositivos de memoria sólida o NVMe of this manufacturer and I wait to continue similar at now.

 

Also I can speak about chips, but not at the moment.

 

I have some experience with that and AMD systems, I can tell and I have a relation with other case, forced timmings a bit and Rapid Mode ON. I don't know if it's your case sorry, never was the mine, but you never will have problems with HDDs with AMD or Intel devices and with Samsung or other too (we undestand about).

 

I would like to continue with yours, I need time for others, thinkings in other places as Space

 

Thanks for the info and let me try if I have a litle bit more for you that I will translate and read yours carefully and time 

 

Thanks all and @ll bye

I have just arranged return of my 1Tb 860 to Amazon 2 months after explaining the issue. ONE thing that REALLY annoys me is Samsung don't put out any warning about this incompatibility. I love Samsung, most of my stuff is Samsung, but this really is just so wrong. To go on selling stuff which can potentially ruin your machine and all it's data is just so wrong.

I have ASUS M5A99X EVO R2.0 mobo, and have tried everything to get this drive working safely but it just has to go back. It DOES NOT WORK! I've done all the rolling back of drivers I can take. Samsung, Please take note (finally perhaps). You know that you should not legally be selling products that don't fit their description, and although you don't explicitly say the 860 is compatible, the assumption of compatibility is there, and the sale is in European law illegal without a denial of liability for use with AMD chipsets. If it doesn't work, tell the sellers and buyers. This is a can of worms you leave open at your own risk Samsung. The law applicable is 'Fit for Purpose' and this is not.

Regards.

I fully agree

I also agree, there is no excuse for the poor customer support provided by Samsung. But using the registry tweaks I proposed in a previous post makes the SSD usable with an AMD controller, which is something that should have been proposed by Samsung as a workaround for AMD systems. I personally use the 860EVO in an ASUS 1215B laptop with no problems at all after applying the registry tweaks. If the speed is reduced it is something that I could not notice in my system.

The "registry tweak" you proposed is not a solution. You're disbling NCQ which degrades the performance, in essence limiting advantage of having SSD at all. It's like removing an infected tooth. Sure, the pain will go away, but you'll have less teeth to chew your food with. If you eat small pieces, it won't bother you much.

But for those who expect to get the performance they're paying for, this drive is a failure for AMD compatibility. Simply go with another manufacturer. I did, and never had to look back.

“The "registry tweak" you proposed is not a solution”

I never said it was a solution; it is only a workaround that can make both devices to coexist in the same system without any harm and a limited performance loss.

 

“in essence limiting advantage of having SSD at all”

That is not true at all! My SSD is still performing almost 2 orders of magnitude faster than any mechanical HDD in random read/write operations, even with the NCQ disabled. Moreover, the sequential transfers are almost unaffected by the registry tweak. You can test that by enabling/disabling NCQ in your healthy system, no matter what SSD you have. Specifically in my system, due to its age, the benefit of NCQ is even smaller than in newer SATA controllers. In addition, AMD has not released SATA drivers for Windows 10 (the Microsoft standard drivers are recommended), which does not seem a good practice anyway. The release of new drivers should add those registry tweaks for specific drive+controller combinations (like in the default Microsoft driver) to avoid hardware failures, and that is something that neither AMD nor SAMSUNG have done in this case. Shame on them!

 

“But for those who expect to get the performance they're paying for, this drive is a failure for AMD compatibility.”

Totally agree. It is a total lack of support, and it should be warned by SAMSUNG. It is something that could have been solved with a simple SSD firmware update, if SAMSUNG have had the will to do so.

I have an 860 EVO 1TB attached to an MSI Tomahawk motherboard with the B450 chipset. I run Linux. I experienced the same CRC errors reported here. However, I believe (fingers crossed) that I have a workaround to keep using the Samsung SSD. The MSI motherboard has 6 SATA ports. The first four are served off the B450 chipset, but the last two connect directly to the Ryzen CPU. By changing my SATA cable to SATA5 or SATA6 I don't have to use the B450 chipset with the SSD. The only negative for me is that this motherboard won't support an M.2 SSD if either SATA5 or SATA6 are in use. For the longer term this will be an issue, but, for now at least I'm back in business.
