Nvidia GTX 1660 6GB Performance

Hi, i have this cards. and hashrates are 24.24 without mod. I just try to make OC.
Can i have more hashrate with this cards with mode or OC settings ?

Hi , with ethminer get around 25.7 but ive changed to phoenix miner and get almost 27.5 using -200 1950 70w


If the following oc setting is used with phoenixminer, you can get 29.5 - 30.2 Mh.

Same here, I tried your settings and it was perfect, now it’s stable

GeForce GTX 1660 non-Super
memory Samsung GDDR5

the difference between Samsung, Micron and Hynix is key

yes , i have a 1660 non super non ti , the 1660 only , with samsung mining 24.18 and with hinyx mining 27.56 .

what config for hinyx mining to 1660 non super non ti?

This is my setting: It’s a Zotac 1660 non super non Ti

for Hynix memory you should try this:

it seems that mem clock should always be -1004

What miner and driver are you using? I have a Galax 1660 non super non TI with hynix* gddr5 and I can’t get more than 22.57 mhs on T-REX with N460.67 drivers.

*I think its a hynix mem, it appeared one time “Hynix GDDR5” and now it only appears “GDDR5”

another strange thing is that it shows 5942MB not 5944MB.

These are my settings for my rig, I can get 27mhs on the 1660 for any memory that is not Samsung, for Samsung memory I can only get 24mhs

Also all cards are Colorful GTX 1660 except for 2 cards which are Zotac

Here is my setup. Hope it helps. I can easy hit 120m/hs on a good day but nothing less than 94M/Hs the rest of the time, stats are down right now or i’d show you the averages.

@panx hey bro we have same gpu any chance you got to increase your hashrate?
