Ha, it seems that it's a bit to tight for most of your nano's.

Here's a softer one.

Link: Here
No reduced core voltage, increased memory voltage (+25mV)
Stock memory clock is 550 with the option to raise to 600max.

Greetings!

Hi @Eliovp! Any chance of getting the last one with a modest core undervolt? It's a huge task to update all my GPUs, so I'd like to settle on the "best" zcash rom before I update them all. I'm seeing perhaps a 3% gain from your last one. With Claymore not bothering to update his linux version, us non-windows folks are looking for whatever we can squeeze out of our rigs, just trying not to get too far behind. Smiley Thanks!


Do you mean after using the "tight" timing rom, the speed of the Claymore miner just increased 3%?

Rom update for Zcash

Zcash Nano Rom  Wink

Link: Here

Reduced core voltage, raised memory voltage (which is needed)

Have fun!

I've flickering problem with this ROM. has anyone tried this rom?


I tried this rom, but was unable to boot to Windows with garbage on screen...

Hey @Eliovp ! Any hints on what clocks are best with this ROM? Can't wait to try it! Thank you very much for your efforts!

@Eliovp at this ROM only the voltages are modded, or any mem timings too?
Cause I can raise my Nano mem clocks up to 550+ MHz, but I can´t see any effect at ZEC mining (stock ROMs).


Yes, modified timings as well.

Hello,
I suppose these roms doesn't work for a fury-x?
Maybe I will try to mod a bios by myself ...


No they do not.

Tried that Bios... having problem to even boot to Windows.  I guess my Nano couldn't take such aggressive memory timings. Sad


It's most likely the memory undervolt..

Maybies is it possible having same bios for fury nitro ? Ethereum bios work fine on fury nitro Smiley

Thanks !

Good to have an updated optimal Bios setting for ZEC.  Wondering what's the best core/memory speed?

The best mining speed is about 50H/s for the 1050/500 MHa frequency. We need better memory timing strap.

Getting on average 48 Sol/s with 1000/500 stock ROM clocks on Claymore 1.0 and 1.1
Getting on average 53 Sol/s with 1000/500 stock ROM clocks on Claymore 2.0

I'm getting the same speed as you.  I believe the higher speed with Claymore 2.0 is mostly due to increased CPU usage - noticed higher usage.

@Eliovp: Any modded ROMs for equihash?

The 800/250 ROMs for ETH are not good for ZEC. ZEC needs fast clocks both for core and mem. I am running the Nanos on stock ROMs with -72mV on core with Trixx.
Giving appr. 28 Sols/s at slightly above 100W per card from the wall (CPU power draw not included).

However Trixx won't undervolt automatically after a power loss and subsequent restart. Afterburner only shows undervolting but doesn't do it actually.
So even a simple modded ROM with just -75mV for core and maybe the same for mem, but leaving the clocks unchanged, would be practical for Nano miners.
