I have (had) Gigabyte GO-W1608A which is a rebadged SOHW 1633S, which I've flashed to a SOHW 1653S with CSOC firmware (currently). I will test the newer CSOK when I get home.
I have some TDK made CMC MAGE01 DVD+Rs and I can't burn them at speeds higher than 4X. Quality after burning at 4X is perfect though.
I'm using Nero 220.127.116.11 and it will eventually say "Burn process failed at 8X" or 6X, after trying for about a minute or so in the Lead-in process. Fortunately, the DVD is unharmed, and I can use it as a blank disc hereafter (but at 4X).
This has been the same with all the firmware versions, starting from the original firmware version (BS02) that came with the original form of the drive. Actually thats the reason I upgraded (not update) the firmware.
So, could this be a problem with the drive itself, firmware or a bad bunch of media.
Thanks to whoever takes his time to read the thread and more importantly, post a reply.
Mind you that I can burn DVD-R at 8X speeds, and I aven't been able to find any other DVD+R media which are rated for speeds higher than 4X.
