ECC ERROR | SM2258XT Topic is solved

[Roman_TS]

Are you sure? Did you check available loaders? Because officially starting from 7.7x there is no limitations on Samsung chips in SM 2258/59 Utility

Yes we had a teamviewer session,
just to clarify, this is my ssd:

I just finished a job with Chinese SSDs using Samsung chips.. It worked perfectly.

Chips id................................ : EC1C983F84CB
Vendor.................................. : Samsung
Type.................................... : 3dv4-64L TLC 16k

An important note for everyone who have SM2258XT/SM2259XT with Samsung chips.

Loaders will work correctly only if there is NO "holes" in Chip ID map. For example, this is a good map without "skipped" IDs:


MEMORY MICROCHIP INFORMATION
-------------------------------------------------------------------------
: : Chip 0 : Chip 1 : Chip 2 : Chip 3 :
-------------------------------------------------------------------------
: Channel 0 : EC1A1AE5 : EC1A1AE5: EC1A1AE5: EC1A1AE5 :
-------------------------------------------------------------------------
: Channel 1 : EC1A1AE5 : EC1A1AE5: EC1A1AE5: EC1A1AE5:
-------------------------------------------------------------------------
: Channel 2 : EC1A1AE5: EC1A1AE5: EC1A1AE5: EC1A1AE5:
-------------------------------------------------------------------------
: Channel 3 : EC1A1AE5: EC1A1AE5: EC1A1AE5: EC1A1AE5:
-------------------------------------------------------------------------

And here is a map, where SSD firmware is using not all CE of the NAND chips. It's not related to bad NAND chips connection, it's about a drive Firmware version. The SUM of ID capacity is the same as the drive capacity, so everything is ok except the allocation if IDs. In this case Samsung Loaders will not work.

Do you think there will be a solution someday?

It's already exist But not for unsymmetric CE map.

Of course ACE Lab developers will handle it - previously it was not possible to work with Samsung memory chips at all. Now - we got a partial solution. In the future may appear a complete solution.

So could the partial solution be helpful for our case with the teamgroup ssd?
If yes, I would love to create a ticket !
Otherwise, I will wait for sure.

Edit: we have the unsymetric case, so we still have to wait, thanks for you work.
