Try
TDP 75,  mem +200mhz (real speed for linux) for starters. Core does not matter much for Eth.
But if you memory is Hynix, don't expect more than may be 17-18.

Or switch to equihash algorithm coin.
TDP 75, mem +200, core +100 for starting point.

Or if you have very cheap electricity don't touch TDP.

Sorry for confusion. Pc memory does not matter.
The video card has its own memory and it can be Samsung micron or hynix.
Hynix has lowest hashrate for ethereum. But you can see the type in windows only by using gpuz program. I don't think you can see in Linux.
That will tell you whether it's worth the efforts to over clock much or not.
It is also possible you have not oveclocked anything thus the lower hashrate (if you have micron or Samsung memory)

If you switch to other coin not using the eth algorithm it would not matter the memory.

Wow, theres so much great information that i collect from this thread,
Many peoples like to share about Vga and their hashrate to do mining,
Im new about this business, and im very thankful about you all that sharing information here.
Keep it up friends, like to share with you all.

What type of RAM on the GPU? What are your settings?

Yes. Unless the price of card is overpriced too much

If you can find it at under $300, absolutely. It's stable, handles dual mining well, generally a low energy user (and can be set to be even moreso), etc. But at current prices I'd say spend a bit more and go with 1070s, more expensive upfront and a higher energy bill, but once you hit ROI you'll make way more off them.

That's about right. You can may be squeeze a bit more but do not expect 600 700.
I get around 470 with TDP 50.  70watts consumption.on 1060 ssc 6gb.

Your GPU has Hynix VRAM, with loose memory timings. At most OC, it would barely push 19 MH/s. With Hynix memory, look for core-intensive algos (Equihash, NeoScrypt, Lyra2REv2, etc). You'll get 10-15% higher hashrate on these algos vs a 3GB GPU (6GB cards have more CUDA cores).

Dagger-Rig [DualMiningw Pascal (-dcri 20)]:

3x Gigabyte Windforce GTX 1060 3GB [SAMSUNG] @65TDP/CrCl+160/MmCl+700
2x KFA2 GeForce GTX 1060 OC 6GB [MICRON] @65TDP/CrCl+160/MmCl+700
1x PNY XLR8 GeForce GTX 1060 OC GAMING 6GB [MICRON] @65TDP/CrCl+150/MmCl+650   

Equally distributed 139MH/s (23.2/card) ethash + 920 MH/s (155/card) pascal. Runs around 24.3 MH/s/card in SingleEthMode. Rig overall power consumption from the wall: 540W (3.72W/MHs)


Equihash-Rig:

6x KFA2 GeForce GTX 1060 OC 6GB [HYNIX] @65TDP/CrCl+165/MmCl+300

1775 Sol/s (293/card). Rig overall power consumption from the wall: 500W. (3.55 Sol/W) [Runs with a low power consuming Intel "T" CPU]

Just keep the HYNIX cards. If you start returning them hoping for Samsung/Micron your rig will probably never go online and you'll miss profit everyday. Just mine ZClassic/Hush/BTG.

Haven't tried other algos (neoscrypt, skunkhash, lyra etc.), though.

Ideally keep temp below 70C and fan at 80% or less, but if you have to live with violating one of these then definitely go with running the fan harder, not letting the temp climb higher.
