I have the same issue 20hash. I tried the memory and clock at anyway and still doesn't work better than 23.

I have the latest Nvidia drivers,

Can you confirm is due to the 452.06 version?

Regards

I have 1 1660 super with hynix memory (MSI ventus xs) and i can get it run to 32 Mhs using -502 core and memory at 62% power limit. The driver i am using is the 446.14 version and it's stable for mining since june last year if i remember correctly. If you think it's driver issue then you can try to download another driver version but are you sure you have the hynix memory? not micron or samsung?

Right.. My memory is Kingston as far as I know and its 4 Gig. And the 1660 super version is the EVGA.

I will try with the drivers and let you know guys , thanks for the tip.

I mean the GPU memory type, not the RAM you are using and you can check that using software like gpu z and it should show one of Hynix, Micron, or Samsung.I already seen your afterburner setting in another post and if you really has hynix memory then you should set both of the core clock and memory clock to -502, not just the core clock like this https://prnt.sc/zcd750

Thank you, Indeed I went down to -502 and worked for one of them, stays at 31. But, the other one stays at 27hashrate. Hynix memory both. I don't know then what could be the reason... Perhaps it's because it's m2 port?

Thanks again for your answer

Hi, what hashrate are you getting with this settings and also what is your power draw? I'm using same settings but my hashrate keeps going down for unknown reasons, I was at 31mh but two days ago my mining hashrate start showing 30mhs

I can see that you are trying to get high hashrate from your gtx1660 super pls lower the memory clock as well just like you did with core clock and you will get better hashrate from 30 to 32 mh per second, you are almost there mate

Lol mate there is no graphic cards with kingston memory, kingston is ram memory, use gpuz to check, download GPU-Z and launch the software it will give you the name of the memory your gpu is using not your ram stick, haha

I know memory type matters when trying to get the best hashrate out of gtx1660 super but lowering the memory clock to -502 and the core clock to -502 works for many, I put power limit on 65% on both a micron and hynix card, if it's samsung you gotta try overclock on core

Could help you find a way around if you can identify the memory chip on your graphic card, to do this go and download GPU-Z and install, it will reveal if you have hynix, micron or samsung memory, some settings works best for micron and not samsung memory

that's right the problem is in the driver version you are using, in version 452.06 it will work perfectly adjusting the memory to -502 and powerlimit to 62% reaching ~ 31mhs hashrate.

To reach the 32 mhs hashrate with 1660 super gpus with hynix memory you don't need to overclock the core, just set the memory to -502 and powerlimit to 62%.

Thanks a lot, having 31Mhs and 49C on my Palit card. Seems like power limit has no affect on perfomance, only on consuming energy. But I really don't understand how it's works - why lowering consuming energy makes no difference to hashrate?

Powerlimit is for gpu core, and for ethash you need memory bandwith, and not so much gpu core.

Guys do you only downclock a memory? Does overclocking GPU and raising power limit boost hashrate? Or it is dangerous?

Works well with Driver 452.06
No risks.

I wan to thank you all for the great help, I would never ever come up with this solution on my own.
I hope I can pay back the favour once I get more experience.

Great community!

Thank you for saying a big thanks to all those who makes a contribution to your problem and I'm glad you are able to solve the problem too, I have 10 pieces of gt1660 super and they are all running on hynix memory, out of the box I get 30-31MHs without any bios modding or flash, it's definitely the memory downclocking thing

It depends on memory manufacturer. It looks like that you have Hynix memory. If it`s so - you ought to downclock memory to -502.

I underclocked it, with no effect, unfortunately

It is Hynix memory. So I guess I'm stuck at 20 MH/sec ? Or should I try a BIOS flash as proposed earlier ?

I have colorful 1660 super with hynix. -502 on memory gives me 31+ MH/S.

Follow the suggestion of user mak013, it's weird, but some memories of 1660s need to downclock to gives more hashrate
I did not believe before but it's true

Here's a link to see some users relating: https://www.reddit.com/r/EtherMining/comments/j4woit/1660_super_hynix_316mhash_eth/

I didn't find the thread here, but there's users from here that suffered the same problem with Hynix.

maybe it's something related to memory timings, when you downclock the memory probably have better timings, but this is just a guess.

Try this and post here
