Hi everyone i BIOS Palit my 1660s gaming x hynix mem successfully BUT always a but… once i reboot my rig the miner didnt want to start properly i change it for t-rex (i was on nbminer before) and it changed nothing. Is someone got that problem before? thank you for the help.
in the pass did it comes with the same problem?
I have a dedicated mining rig instead of a PC in which I can plug the GPU(s) in. Is it possible to do the bios mod remotely via MacBook (which obviousely is not connected to 1660S)?
大兄弟，能给我一份七彩虹1660s原来的bios吗，有一张不稳定，但我忘记备份了😿
Can I have a copy of your colorful battleax 1660s BIOS? One is unstable, but I forgot to back it up, than you!
What about SC ultra? Still can’t get it stable. The rig restarts every 2 hours and does not show PL correctly. How did you fix it?
Roll back original rom and no headache.
I’m a bit late 
Have you already fixed?
1660s which producted after 2022, shouldn’t be flashed. If you do so, you hiveos will not be restarted successfully.
MSI Ventus XS OC Using the stock firmware in this code : 90.16.5A.00.19
cant using the MSI or PALIT bios if anyone have the same problem ?
Hi Yes same problem but u can flash any of these bios but only works on windows rig and not on hiveos . no user why. if anyone has technical reason, please
yes, it is. hope new bios for new 1660s.
I have been with this same card for a week and there is no way to modify the bios, neither with palit nor with msi. Hiveos crashes within 5 seconds of booting.
And on the other hand, with the underclock values for hynix, it cannot go beyond 28.5 MHS.
At least I haven’t been able to do anything else with this card
I’m considering returning it
hello, i have the same problem , no one of bios mod working on hive os, but with 1185/2900 value, i have 32.35 mhs, 12 hour tested without problem. this new gpu have manfacturing date december 2022
The memory at 2900 is not too much? I am getting 30.4 at 1050/2200 I have not dared to increase the memory value more
I have flashed rig of 10 asus tuf dual fan with palit bios. Took long time to find stability and is different mclk for every card to achieve such. Trex does not always show which gpu causing the crash which is frustrating but persistence will lead to stability. If ambient temp changes due to warm days may have to lower clocks even further.
I have never had an issue with fan speed or watts being reported if using drivers 460 series or lower. I have noticed on three separate cards the watts did dramatic jumps ~20watts after mining stable for many days. I reflashed palit bios in every instance and on the first two cards watts returned to normal range (62 to 86watts varies on card) however on the third this watt increase seems permanent (94watts from 74watts) Going to start monitoring wattage from wall to validate software readings.
Wondering if anyone else out there has encountered this and there thoughts and efforts to resolve?
ventus 1660 super right ? 1100/2400
depend of what the temp you want to aim and the fan speed you want to set.
ASUS gifted you with their DRM bios locked 1660 Super, now you can’t bios mod those with hynix vram anymore
Got several of those cards, hynix vram, came with new bios, tried to flash it then os reports nvidia drm error and hang . Thanks to ASUS being so nice
The TUF 1660 Super with new bios version:
Hynix GDDR6 · 90.16.5A.00.32 · PL 70 W, 125 W, 150 W
