Happy weekend everyone! I have a weird issue that is occurring on my 2nd mining rig and was wondering if anyone had experienced similar and/or had any suggestions on what to tweak to try and fix it. Here's the scenario...
Rig Details:
- i4790k CPU
- ASRock H81 Pro BTC R2 Mobo
- 16GB RAM (2x8)
- Win7 Pro
- 16 GB Virtual Memory
- 1200W Plat PSU
- Claymore ZEC Miner v8
I had 2 MSI 470's running for 3-4 days very stably. With no tweaks at all, were running about 160 S/s. After undervolting and setting core/mem clocks to 1300/1900, they were producing about 170-175 S/s. I had an issue with strapping the first GPU, so reverting back to original BIOS.
After the molex cables from Phil arrived yesterday, I hooked up the 3rd GPU, a Sapphire 470 8GB. This also ran fine, providing about 180 S/s with no mods (but it comes factory over-clocked). In addition, the 2 MSI 470's were still running at previous speeds.
The problem started after I hooked up the 4th GPU, another MSI 470. While my system recognized it fine, after running Claymore for a while, I realized that the hash-rate on all 4 GPUs had dropped. Now, the 3 MSI's are barely getting 150 and the Sapphire about 155... so, all are about 25 S/s short. Even stranger, when I set the core/clock speeds of the MSIs to 1300/1900 in afterburner, it has no apparent effect on speeds.
I am using the exact same config file with Claymore v8 as I am on my first rig and all other settings seem to also be inline, but all 4 cards on rig #2 are running about 25 S/s slower than they should be since I added the 4th GPU. I double checked virtual memory and it is set to 16GB just like rig #1, so not sure what else to check.
Not sure this matters, but I have the 4 GPU's plugged into slots 1, 3, 4, & 5 (all x1 slots). Slot #2 in the x16 slot and although Phil sent me a ribbon riser, I still need to figure out how to connect it given the design of my rig. So, after running with USB powered risers in slots 1 & 3 stably, I added the Sapphire to slot 4 and then the 3rd MSI to slot 5.
Anybody seen anything like this before on this or similar Mobo? I know there are tons of people running this Mobos at full speeds with 6 GPUs, so I must be missing something. Any suggestions would be highly welcomed.

So, can i ask which pool most of you here are using for ZEC? I have been on flypool since the start and the payouts are very quick and reliable. However, I am beginning to wonder about what seems like a pretty big hash-rate difference as reported on their dashboard vs what I see directly in Claymore. My 2 rigs are currently showing 1,050 S/s consistently but my avg hash-rate at flypool is around 960. Not only that, but the range of reported rates is still all over the place on flypool. In the last 5 hours alone, it showed a high of 1130 and a low of 770... all this time both rigs were at full capacity. I don't have a huge problem with the spikes as long as the average H/R is being recognized correctly, but it seems to be about 10% short.
Is this normal? Wondering if I should try Dwarfpool or Suprnova as both seem to be getting some love in other threads I've read.

I recently switched from flypool to suprvova, since I've seen reports ( probably here
), as a test. It will take a few days to seeI may switch on the weekend.
@ LoneRangir As a complete aside please watch for your package I sent It has a holiday surprise gift.
@GabryRox your package should arrive today.
it isnt the pool thats the problem..
even at nicehash with claymore its all over the place ill be at 700 one min then 1300 the next
i only found that optiminer gives the right amount more consistent than claymore but it is slower than claymore anywhere from 20-50 sol/s

yup, i have read way to many posts about the problems with C9 so will be holding off on updating for now. I suspect Claymore will be able to fix or at least mitigate the power spike issues that seem to be causing most of the problems. Doesn't seem worth that hassle and probable down-time for my small operation, so will see what happens in the next few days.
v9 is apparently worth trying - quite a few folks have reported better hashrate out of it when it works at all.
Scrypt mining, like Dnet work, was compute bound and soaked a LOT more power than ETH or ZEC do out of the same GPU at the same clocks.
Probably easier and quicker to set up the dnet client for "high stress" testing though.
Wasn't that long ago that a lot of "review" sites used the dnet client and/or Prime95 as a deliberate "stress test".

I notice the same on the flypool. It is usually 5-7% lower than the reported by Claymore.
The Dwarf is similar to that reported by Claymore. So it is quite strange, should be at least 2.5% lower due to the 2.5% fee.

yes I was pleasantly surprised to see that it is out for delivery today as the original ETA was tomorrow! That means I should be able to get my 2nd rig running with 5 GPUs by tonight. Thanks again!

According to current profitability, I guess most of you guys are now mining Eth (except for the rigs that need to get lower power consumption, where zec can still be interesting).
What pool do you use nowadays ?
Is ethermine still a good choice, with fair payouts ?
Many of use noticed their new zec pool, flypool, was not very fair ...

With the 7990 cards and the 7950, I still mine the zcash. But they are very undervolated and under clocked.

Claymore's Zcash Miner is Updated to v9.1:
- additional range checks in code for better stability.
- reduced devfee, it's 2% now (72sec instead of 90sec) if you use secure SSL/TLS connection, currently Flypool and Suprnova pools support encrypted connections, see Readme for samples.
- improved "-di detect" option: now after GPU order detection miner starts mining with the detected order.
- added ability to use environment variables in "epools.txt" and "config.txt" files. For example, define "WORKER" environment varibale and use it as "%WORKER%" in config.txt.
- additional range checks in code for better stability.

Make sure to use SSL/TLS in order to get the fee reduction!

I'm supprised it's dry enough where you're at for evaporative effects to be noticeable at all.
I'm mostly all-in on ETH now - my dual 280x rig is still ZEC 'cause it's a tossup either way, and the older HD7750/HD78x0 cards with 2GB or less are ZEC 'cause they can't mine ETH.
XMR is WAY far down on profitability on every comparison I'v ever done. THe only thing I have running XMR is my older XP-based gaming machines 'cause it's the only thing I CAN run on the GTX 750 Ti in that machine - but the pools I've tried seem to only like giving me about half of my hashrate no matter what I try, and the payout thresholds are crazy high.
Claymore v9 seems to be VERY iffy - everything I've tried it on is NOTHING BUT REJECTS when it runs at all, and quite a few other folks reporting it don't work well if at all.
well not all countries are uniform in their respective climates, there are locations where there could be different temp, humidity etc..being near a forest, a river, the winds blows from the east, the altitude etc... Evap cooler fans are being sold here btw.
My rigs are stable at claymore v9, after the release of v9 i was able to mine with -i 8 and -i 7 but the miner experienced restarts after 24 hrs or less of mining (using -r 1)..so today i lowered it to -i 6 ......but that's only for my 280x rigs, the rest are fine
there is also this power spiking issue that Claymore needs to fix - I have reverted back to v8 for some rigs but most rigs are OK with i=5 and i=6
I will be posting some pix soon as soon as I get the blower re-positioned, etc.
I just reduce the voltage and frequency for the AMD R9 Nano. I run them at 920/400MHz instead of 1000/500W.

Sorry for off topic but SOS to all gurus out there - I dont want to drive 30mins to the warehouse...
one of rigs R390 x 5, screen went black, after upgrading to Claymore's v9 ZEC miner.....
from my remote terminal at the warehouse I could VNC into it, network is alive not dead.... but screen is black!
Sending Ctrl-Alt_Del command via VNC is fruitless since screen is black and I cant see anything...
How do I issue an RPC command line to reboot the PC in the same network?
The only remote access app running on that PC is VNC.
Any ideas? maybe a netuse command
Wish I have the SRR installed ....

my other rigs are fine even with -i 8 maybe because my PSUs have allowance in power draw even if i switch to scrypt mining (notorious for maxing out cards power draw).
Arielbit.... you use your GPU to mine Scrypt?
no, i'm only mentioning scrypt here because i like to point out that scrypt mining (as i experienced back in 2013-2014) is my standard in budgeting PSU power to GPUs today.
Even 480s are budgeted to me at 2x card per 750w..i know it uses less power than 280x's but it just made my psu more efficient..(if you look at the efficiency curve of a psu) anyway if claymore updates his miner for more power and more hash, my psu's are ready
update:
my 280x rig stabilized when i downclock my 390 in there to 1110 core from 1130 at -i 8, funny while my 4x 390 rig is fine at 1130 core -i 8 since v9 was launched...my other 280x rig is fine at -i 7
