johnb:
Should I go for -6 of -7 on my clip+?
I did not have any re-read numbers with -6 so far ...
Mihail Zenkov:
Try v8: http://knk.square7.ch/cvdd2/rockbox-clip+-cvdd2_scaling-8.zip

Hi Mihail,
slightly off-topic, but maybe this also provides additional information:
I have tried -6 and -8 on the clip+ with the potentially dying internal memory I described here:
http://forums.rockbox.org/index.php/topic,51304.msg237134.html
With the current dev builds the crash (see picture) happens maybe every 3 or 4 weeks with daily usage, I believe when RB tries to write the .playlist_control file. All my music is on the SD card.
With -6 I had one bookmark, which triggered this reproducible. Also happened during playback sometimes.
With -8 this happens within 5 - 20s when I start playback!
I tried to increase CVDD2 to 100 and 110 in the debug section, but it didn't help.
So it seems that my internal flash needs higher voltages to be able to write.
------------------------
I will try -8 with a different clip+.
johnb:
Different setup:
clip+ variant 0 with build -6:
Kingston 6GB: 0,0,51,0 in debug menu, number keeps increasing, but no noticable impact on playback, UI or responsiveness -> usable
Samsung Evo 64GB:
1. start from recent bookmark, skip to beginning: WPS updates but stays at 0s, no playback, backlight shuts off
2. skipping has a lag of 10s sometimes
0,0,21,84
--> not usable
Lexar 64GB: seems to always stay at 0,0,1,0
Single occasion where after seek in a flac file, WPS updated but playback did not continue, the UI stayed responsive.
Numbers above did not change!
-> usable
I have NO clicks when changing volume above 0dB. Faintly noticeable delay, not annoying.

Special build for this player: http://knk.square7.ch/cvdd2/rockbox-clip+-cvdd2_scaling-8_sd_only.zip
You should install it on sd card. It should mount only sd card so all your setting will be saved on sd card.
