My second ZEC + XMR+ ETH thread builds info links thoughts and photos.

[AriesIV10]

I was having problems with ZEC (freezing/gpus falling off).  I added a larger PSU to my rigs and WALAH!  Running steady NOW!

7 MSI RX470 Gaming X GPUs
1641 SOLs
234 SOLs per GPU
1117 Watts, 9.60 Amps at the wall
1.47 W/SOL
V9.2 -5
1990 mem, 1290 core

Hope this helps someone.

Aries, out of curiosity, what sizes of PSUs were you running before and after on this rig?  Curious because assuming I can get 6 GPUs running this weekend on rig #2 and might switch over to ZEC.  I have 1200W so I doubt it will be an issue as I should still have at least 25-30% headroom, but I know that since v9 there has been power spike that cause issues for some with either low quality PSUs or not enough headroom

I have 6x RX 480 on EVGA 1300W. It runs ETH and ZEC on latests Claymor's miners with no issues

Nice to see ZEC back up in a more profitable mining range now, even though i don't hold much of it and not currently mining it.  The dynamics of this situation are quite interesting to watch. Last night, I almost switched my ETH rig over to ZEC, but thought better of it on the off chance the rig crashed overnight and I lose all income from it. Was planning to switch today but when I checked first this this morning, ETH was actually atop the profit list. Even though the price is down, the diff dropped WAY off.  But when I check about an hour later, ZEC back on top but all 3 (incl XMR) were within a few cents of each other.

One thing I noticed though in comparing whattomine & coinwarez... they have the same diff for ZEC and XMR but are WTM shows WAY higher on ETH, which greatly reduces their prof estimates.  As of checking 5 minutes ago, WTM has ETH at 83.7 while CW shows it at 78.3.  Not sure which one is correct but would assume CW, since ETH diff is in freefall mode.  Bottom line is that I wish I had 3 rigs so I could have 1 on each

I have 1200W Platinum PSUs on the unit, but the power consumption keeps on increasing with each new version of software.  I have now attached 1600W PSUs to the units which gives more headroom for wattage.

thats why I do 4 card builds

Phil, That is a very good technique.  I may want to reduce back to 6 gpu systems.  The 1600W psu's are very pricey.  I can get the 1200W Platinum psu's for about $150+/-20 on Amazon.

That can be a great deal!

The cheapest 1200W platinum I've seen was ~$185, but usually they are ~$200

[philipma1957]

Oh I got the EVGA  to work  with the M2 slot  so I kind of like the board.  Of course sale is over.


We found the plat rosewill quark as low as 119 for 1200 watts

Yeah, I really like that Rosewill too... also have the 1000W version running my 4-card rig. I really wish I would have bought 2 when they were at $120, since now the best price is $160.  That and the apparent rise in RAM prices are what is currently holding me back from completing my 3rd build.

Is this PSU enough for 2x Rx480?

While we're talking about PSU's: does anyone have a way to pull data from their PSU's?
I know Corsair Link is one PSU that can do that .. Do any others? I'm trying to find a way to monitor lots of power going to individual rigs on a large scale.

I would say yes. I ran two cards on a 550w without problems

Maybe thermaltake?

citronick:

I think you have a r9 fury cards in your rigs. How are they comparable to RX 480 in ETH and ZEC?

No Furies - just the R9-Nanos 4GB HMB memory. R9-Fury is the one with liquid cooling no? Too expensive that card. Nanos were equally expensive.

Personally for me in my farm, Nanos are amazing for ZEC, topping 320-330 H/s per GPU, also not bad of a performer in ETH. Easily rom modded for undervolt and OC too.

The 480s are very good in ETH mining, esp with modded roms, 29-31MH/s per GPU, -100mV or more, and - undervolt.

Meanwhile, the 390s are also fantastic mining all 3 fav coins - ZEC, ETH and XMR but its power hungry, huge, long and old card.

Best card for ZEC in my farm: 390, Nanos and 480s (in that order)

XMR: 390s and Nanos (they have many compute units so good for ZEC and XMR)... but 480s low performer, not stable for XMR - Claymore needs to work on it.

ETH: 480s. 390s and Nanos (in that order). All 3 card types full cylinder will deliver about 3.8GHs for ETH.

Future: 480s or RX series, should be card of choice - lower power consumption, good cooling and Claymore optimised to the last juice, for ETH and ZEC.

Ah - nanos!

Actually Furys are way more cheaper than nanos - $250 vs $470 (new on amazon)

Great statistics data - appreciate it!

Merry Christmas everyone. Just wanted to take a moment to thank all of you on this thread who have been very kind, patient and helpful educating a mining newbie like me over the past 2 months. I am still not where I want to be but have learned a lot and hope to continue that and leverage it into a profitable 2017.

Here's a quick update on my never-ending battle to get 6 GPU's running on my 2nd rig... yesterday, I took another shot at strap-modding the bios of my MSI 470s.  My first attempt about a week ago to mod GPU #0 didn't work for some reason and I had to flash it back to original settings.  This time, I unplugged my orphan Nitro, rebooted, and flashed dev #1 with the modded bios.  Reboot went fine but upon checking DevMgr, found the dreaded error 43 on presumably the card i flashed. Tried running the 6xGPU mod a few times but no dice, so I re-flashed it with original bios, rebooted, plugged the Nitro back in I'm back to "normal".

What i don't get is why the exact strap-mod I used on the exact same GPUs on my other rig (same W7) doesnt wanna work on this rig... 0 for 2 now. I'm sure I am doing it right but this rig doesn't wanna take it.  The only real difference is the Mobo between the 2 systems.  Anyway, I'm at the point where it probably makes sense to strip this thing down, run the driver cleaner, then re-install the GPUs one by one, maybe flashing each as I go.

But, then I got to thinking... if I'm going to basically re-build this thing, I might as well install Windows 10, since I have heard from numerous people that this is a better OS for anything over 4 GPUs.  And, it looks like I can still get an upgrade for free so probably worth the shot.  This time I am going to try plugging the 1st GPU (and monitor) into slot #2 (x16) since starting with slot #1 last time may have been causing some of my issues. Hopefully, W10 will let me get 6 GPUs running and modded. That should get me about 40% more hash-rate on XMR vs what that rig is currently doing.
