hynix
You sure it’s a « super » as I have a evga 1660 Ultra with Hynix but it’s DDR5 and not 6 so my settings are 1300 GPU and 1300 memory… gives me a bit over 25MH and it runs at 62watts
If it’s a super, I would think you can use the same settings for mine which use Hynix and that’s absolute GPU core of 1000 and memory -1004 which gives me around 75watts and 31.7HR
Mine 1660s SC ultra is gddr6. I don’t understand why I can’t undervoltage… Unlucky
How does this look.? New to HiveOS and just got a single card up and running. Any recommended changes? Also, what does the 22% represent?

The 22 percent is the fan speed percentage. Keep an eye on your temps… I usually have mine around 40-60% if need be
48 degrees is decent and you are not using the fans too too much to wear them out faster, … mine hover around right now 50-60 degrees with fans blowing on them too
Room temp is 24-25 degrees.
For your settings, you could try a GPU setting of 1000 rather than just leaving it at nothing…
these are my settings, rock solid… .
Pretty sure Micron memory settings are different than Hynix… if I’m not mistaken they are actually overclockes and not under clocked. Take a look in the forums to see what settings to use as I personally don’t have any with Micro memory
After trying all the OC’s mentioned in this thread +930(core) and -1004(memory) is the best OC for 1660 Super’s with Hynix memory…
I have since changed my supers to 930 GPU core and yeah a nice little bump up and still stable. Thx!

Try to put all cores to 1050 power limit to 75 and see those wattage to drop to 75 ish.

bro… it does not help if anything it drops the MH/s a little bit… 930 and -1004 seems to be the best OC
what kind of asus do you have? i have the tuf oc version. super stable mining for weeks without stales or rejects
damn… GPU no 2 only using 57W… wowww…
let me put up these OC’s for a while and see…
yup, i won the silicon lottery on that one.

Bro… i have tried core from 1050 in decremental order and it seems 930 is the best suited for 1660s with hynix memory…
Also an suggestion for you to keep the PL on auto(0) and the cards with Hynix memory to 930, it might pull a little more MH/s for you.
Mixture of MSI / Gigabyte GTX 1660 Super’s (Total 10)
Cards with Hynix Memory run the hottest
Cards with Micron Memory seem to run the coolest
Cards with Samsung Memory right in the middle
Avg wattage around 70 (702W for 10 Cards)
Please note that the -1004 memory setting does not actually work on all cards
1 extremely generous MSI running Samsung Memory at only 59W
