The big VTC Vertcoin settings thread

[Hank Yankell]

Great thread so far guys, keep it up!

I'm just getting started with scrypt-adaptive here, feels like scrypt all over again, doesn't it? 

Here's my findings so far on a pair of Asus R7 260x's. Bonaire's a pain in the rear as usual. I'll post for my 7870LE's, 6950, 7950's, 7850's, and R9 290's as I figure them all out and optimize them. I thought I'd work on Bonaire first since there's not much info out there.

I'm mining with CGMinerAleks_NR3, as I can't get anything to work on these Bonaire cards with Vertminer 0.5.3.

Here's my .bat:

cgminer.exe --scrypt -o x -u x -p x --failover-only -o x -u x -p x --no-submit-stale --gpu-platform 0 -w 256 -v 1 -I 20 --lookup-gap 4 --gpu-threads 1 --gpu-fan 65 --thread-concurrency 14208 --gpu-engine 1200 --gpu-memclock 1800 --gpu-powertune 20

This nets me around 117khs per card. No HW errors. Strangely I got the best results with one thread and a lookup gap of 4. It looks like these cards can be pretty energy efficient if you have enough of them going, but I wouldn't run out and buy a bunch of them. They only pull about 250khs on normal scrypt.

If this helps anybody, feel free to tipmeh!!!

Hi, Could you share your settings for 2xasus 280x?

[ieatm3s]

Anyone mining with a 1GB 6950 ? I get 130Khash out of it with -I 12, TC 4096. if I go to 13 I get to about 180khash but with HW errors  The only thing I saw so far that influenced my hashrate were TC and Intensity.

Hi all,

Wanted to share my experience and config. Please give me feedback if you have anything that you think looks strange.

I'm currently getting 480KH/s per card with no hardware errors. Temp was around 86c the first 24 hours. But it has increased to 90-91c. I'm guessing the rooms general temperature is increasing (no open window and door closed). I have no chassi and no external fans atm, I plan to get the temp down after I modify the rig more and find a solution where I can have the window open.
The 290 are spaced with 2 pci slots in between. So it's only the "inner" card that gain to 90c. The "outer" card is stable around 75-77c.

It has been going on very stable, however, it crashed this night at 02:45 with nothing explained in the logs. First unannounced crash so far. (meaning when im not experimenting)

My gear:
2x Gigabyte R9 290 OC Windforce
1x 1000w
2x 4GB DDR3 1600
1x SSD 60GB (faster booting)
Win7x64sp1

My config:
gpu-engine 1070
gpu-memclock 1500
gpu-powertune 50
Intensity 20
temptarget 80
temp-overheat 95
temp-cutoff 98
tc 24550

I have been able to go up to 955KH/s stable on scrypt also with this config.

Oh and I'm going all in on VTC  



update:

open door and cranked window and the temp is steady around 85/86c with 481KH/s per card

Hi, Could you share your settings for 2xasus 280x?

I'm running two 7970 Matrix Platinums (same as Matrix 280X) at 365 kh/s each with same settings as regular scrypt @ 1050/1500MHz:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

vertminer.exe -u ComaWombat.1 -p x -o stratum+tcp://stratum.vertco.in:8080 -I 13 --thread-concurrency 8192 -g  2

Without the setx-commands the other card only got ~20kh/s.

Hello guys! I do not know if anyone had the same problem but when i mine (any vert pool that is) my cgminerAleks.n3 shows 310 and 350 on each of my R9 280x whereas the pool shows 15-55kh/s
Can you help?
It appears to run ok and accepting..

First, check your HW errors. If you have a lot of errors, then the pool isn't receiving much work.

Then, just wait. The pool will catch up. It estimates your hashing power from the number of shares to submit.

I'm mining this over @ http://vtc.dedicatedpool.com with the latest cudaminer 2014.2.6  x64...all thats needed is the ( --algo=scrypt:2048 ) flag, omit your current warps setting & use auto tune.

My card is a GTX 650TI Im getting just about 95 kh/s  if you have the same card as me try ( K4x24 )..if not use auto tune.

GPU is OC'd n OV'd YMMV.

Searching through this thread, I saw some fairly alarming posts from folks who said mining vertcoin may have caused some damage to their cards. Has anyone else experienced this?

Nothing so far. A higher state of instability with an R9 270X is about the worst thing I have encountered. On the other hand, I installed a 270 last night and I have been able to get about 224 kh/s out of it, but I have to tweak my car arrangement in my rig because this card is running ab it too hot so i scaled it back to 201 kh/s for now. My 270x is only running around 180 kh/s right now.

Got that two days ago during trying to tune my 2x R9 290x with vertminer 0.5.3 linux 32-bit. One fan went mad and the card got really hot. Even cold reboot didn't fix it.

I finally switched off the whole thing for about 2 minutes and started with safe settings for normal scrypt on my cgminer-kalroth installation. That did the trick, everything back to normal. And vertminer works normal again after that, too. Problem didn't come back so far <knock>.

Yes, it's more about WU as some people say, still, 1/3 the WU from what I was mining in scrypt. My concern is that only conservative settings will be stable in vertminer, compared to more aggressive settings in cgminer for scrypt.

I think he means that you need to consider the price of the coin. I'd get ~$4/day with my 7850 hashing 365kh/s scrypt. I can get $6-7/day mining Vert at 160kh/s. Even if it went down to 120kh/s its still $5/day and better than normal scrypt.

Exactly.

whats your config for the 270 (non x). I cant seem to get my gigabyte 270s stable with any of the settings in this thread.

EDIT

Currently testing the following (5 Gigabyte R9 270 non X)

-v 1 -g 1 -I 17 -w 256 --lookup-gap 2 --thread-concurrency 12992 --gpu-engine 1086 --gpu-memclock 1475 --temp-target 73 --auto-fan -- temp-overheat 85 --temp-cutoff 90


Here's what it looks like so far

1 hw error right when I started but havent had one since. I will report back if it becomes unstable

Hi,

I got my wallet locked after a hackattack to Kilovolt server. Now the wallet shows it is locked and wont sync. I have encrypted the wallet if that means anything. Would someone know how to resolve this, please? Reinstall surely didnt help... tried contact vertcoin admin, no answer.

Notification that shows when wallet opened: "Warning: displayed transactions may not be correct! You may need to upgrade, or other nodes may need to upgrade."

I would really appreciate the help.

My settings are currently conservative because of the temperatures (ASUS R9 270. many reports of high temps with this card), but if I recall, the ones that gave me the highest numbers were:

core/mem - 1100/1250
vddc - stock
powertune - 0
lookup-gap - 2
gpu-threads - 1
intensity - 19
thread-concurrency - 12288 (I'm not convinced this is the best TC, but so far it's ok. I have still been fighting some HW errors but they are very infrequent)
worksize - 256

If it helps anyone out there:

I tried this and got a lot of HW errors on my XFX. got a picture for proof?

GPU0: 7950
GPU1: 280x still working on config
26hr mining results with my current config

It's impressive how you manage to get that high on your 7950. I can't get over ~280Kh/s on my Sapphire 7950 Dual X with any of the combination I have tried so far.

Impossible. Gpu 0 must be 280x, and gpu1 is hd7950. Check it.

I added a 4th card to my rig and what used to be my 3rd card is now identified as my 4th. That really screwed up some configurations!

[anyone4u]

I added +4 GB of RAM and I can mine. However, in a rig of 1 7950 and 1 280x, only the 280x is working properly with 290kh/s. The other one gets 7-8 kh/s. Any ideas?

7950 same prob if u find out plz tell me

[anyone4u]

Getting around around 290/300 kh/s with 7950 sapphire dualx with boost 3GB  No HWs

-I 13 -w 256 --thread-concurrency 8192  --gpu-powertune 20 --gpu-engine 1100 --gpu-memclock 1500  1.187V VGPU

same card
same settings, no powertune, stock voltage no matter what settings i set i get 8int on window see

[Sinyk7]

something else must be wrong. your miner reports your intensity is 8, not 13.
