Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[joe50]

Undervolting reduces power consumption. You need to fine tune it to get best hash per power spent ratio.
Undervolting usually means hash reduction, but it's ok because it also gives you better electricity consumption, so in the end you are earning more.
If you are not paying for electricity undervolting is not necessary

Actually undervolting your cards is good in all cases where it does not reduce the hash-rate, even with free electricity.

Undervolting will reduce overall power consumption, which in turn will reduce the heat produced (can be an issue even in a dorm room), as well as reduce the needed power capacity of your electrical system. Most free electricity arrangements usually only have minimal circuits to use, so reducing the overall wattage a rig uses will maybe allow for more rigs to be installed.

i really appreciate your answers to my questions.
thank you all.

Do you think your ZEC or ETH miners will be able to take full advantage of a 2048-bit memory bus or is it too wide?

He does not know the definite answer until the card is out.

[bardacuda]

I'm not asking for hash rates for any specific card, just asking about bus width. He's already said that he can't take full advantage of Fiji's 4096-bit bus, but the 512-bit bus of Hawaii is fine...so he must know something about optimal bus width.

I cannot predict it, need to have new cards here and test them.

[bardacuda]

Ok thanks for replying!

@claymore

Are you planning to release a new/faster version?
Second, are you planning nvidia support? 1080TI performs wonderfull on equihash.

Thanks

does undervolting gpu also reduce the gpu temperature?
and if gpu temperature reduce, does also reduce hashrates?
or what is the purpose of undervolting gpu?

undervolting saves power and heat.

as long as the clocks are the same you will get the same hashrate at lower power and heat.

i run my 470s at -100 and my 390s at -75

Hi there, sorry for these noob questions.

Speaking of undervolting- using watt tool or msi afterburner, it shows there the (GPU MHz and its mV) and (Memory MHz and mV).

Now If i do the undervolting, should I put the same mV for both them? or the mV of the GPU MHz got a different certain mV specific to it and the Memory MHz mV has its own too?

Sorry for these, I really wanna try to do undervolting and I need your help guys because my RX 480 hits at 77-82 C temp.

My 480s run at a constant 69 degrees, even the 390 is only running at 70.  No undervolting, standard clocks.  Just open case miner.

Hell I have been running my 280s for 3 years and have not had one fail.  Good air flow!!!

[joe50]

any way to make my shares start from 100 above whenever my system or miner reboot?
i mean total shares always start from lowest to highest when you boot up system or whenever the miner restart. is there a way i can make the total shares start lets say from 100 plus above?

i believe more total shares more money it generate.

Edited:
i noticed that whenever the shares (total shares) gets to 101 i start getting rejected shares from 1 above

i.e.  total shares: 101, rejected: 1

[ITDiver]

@Claymore, do you have in plans new version with 570/580 support?
Faces with problem on my cards, for 570/580 claymore miner works with --fanmin and -tt option very strange.
(fanmin is ignored, with -tt 50 I see 100% fan jumps to 0 in cycle every few seconds)...

What are you talking about? as soon as you reset the miner the shares start at 0. That doesnt mean that your previous shares doesnt count..

70C is very safe temperature.

anybody mining ZCL?

Check your VRM temps as well

i know that... it seems you do not understand my questions.

Anyone else received the blue screen of failure to executed of none executed memory yet?

If the GPU temperature is low, it is a good indication that the VRM temperature is also low.

Problem happened to me on Win 10, I reinstalled win 10 and the 16.12 drivers for RX 4xx, 17.5.1 for RX 5xx.

This fixed my problem and was able to get 6 gpus running on H270-Prime PLUS.

@Claymore

There is no option provided to change(or pickups up max available) Computing units as it still configured for 14 CUs, however Rx 480 supports 36 CUs.
Please put some light on how to maximize the usage?

He does not know the definite answer until the card is out.

 Fury/FuryX/Nano also had a super-wide memory bus - same width I think?

 VEGA is basically the next generation of the FURY line, similar to how the RX 4xx/5xx line are the next generation of the mid-to-upper part of the R9 lines.

 It does appear that AMD intends the VEGA generation to extend somewhat lower in their card range this time around though.
