Hello ppl,

I wonder if you can help me. I am very new to crypto mining and have some issues with my 6x Gigabyte GTX1060/6Gb rig.
I have started to mine HUSH with EWBF’s CUDA Zcash miner and for some reason I can not OC my GPU to what everyone recommends (+107/+926/ 85% power). The most I can get, before my miner and afterburner gets in to not responding mode is +105/+420, power 115% and get ~1890 sols/s total.
Technical info:
Motherboard - H81 pro BTC 2.0
PSU - Corsair HX850 850W
GPU - 6x Gigabyte 1060/ 6Gb
4GB Ram,
120Gb SSD
Windows 10
Driver version - 384.94
First I thought that it is something to do with my PSU, but I see people successfully overclocking their 6x1060 rigs with 650W PSU.
Is it something to do with driver? Bios?

Thank you for your help.

anyone? :)

What miner + settings for that miner are you using?
Are you pushing intensity up on the miner as well as raising the cards' core clock, or just one at a time?
Also, are you sure the 850W is enough for all the GPUs running at full? The power draw on my 2x 060 6GB card when I'm mining at 130% clock on Monero is almost 230W and I still bought a 1000W PSU just in case.

Overclocking of graphic card is NOT an obligation, it is a possibility. Each copy of graphic card has different oc potential, and you cant not expect that your cards will oc @+105/+900 - there are VERY high results especially for memory. On the other side setting +900 without step by step examination was very risky and you have a lot of luck that you didnt smash your hardware.
First of all you should make an accurate, step by step tests of each card to find max frequencies for proc/mem. Than after that you could make tests. Results +100/+400 are quite good, dont count for getting +900 for memories, only max luckiest people have as overclockable cards.
If your mining is crashing after oc, try decrease clocks, until you will get stability.
A starting condition is that on default clocks you have 100% stable work

GTX 1060 is a 120 W tdp GPU.
At 115 %, you are at 138 W per GPU, then 828 W.
Then, OC a 6 x GTX 1060 mining RIG with only a 650 W PSU seems impossible.
But you have a 850 W PSU and mathematics tell you that is not enough (850 W = losts is too low for your 828 W needes).

I am using EWBF’s CUDA Zcash miner. I didn't do anything but standard for this miner.  my scrypt is:
miner.exe --server hush.suprnova.cc --user______ --pass x --port 4048
I am very happy with 1900 sols/s rate, but I heard that many people do under voltage (modd BIOS or whatever) and get the same sols rate with lower power consumption.

However, thank you for your help guys!

Try this config with MSI AB.
+155/+100 Core/Mem. Power target - 70%. It should provide pretty results.
Moreover, you're overpowering your GPUs and PSU. No need of 115% Power target.

Thank you for your advice, However I have tried these settings, but I only got ~1720 sols/s. Now I am running stable for ~13hrs with  average 1895 sols/s, using +165/+455, 95% power. I will try to play a bit more with power to save on electricity bill.
