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

[PPOC]

Stock 295x2, -i 4, 1100/1500, 320 H/s
Stock Nitro 470 8G, -i 4, 1350/2100, 155 H/s

In the 295x2, your running 1100 clock, 1500 mem and how about power limit? I have same card and getting 290ish.

0%. Haven't touched power limit. I use TRIXX to overclock. This is on Win7 x64 Ultimate, Crimson 16.10.1 if that helps. Temps are 70C and 67C, ambient 26C.

Maybe your card is throttling? How's your temps?

Temps not an issue, with ETH I was at 71-72, with ZEC its much better at 59-63. throttle does not kick in till 74. Same win7x64 ultimate, same 16.10.1. Using the default AMD setting to OC. What CPU, RAM and MB are you using? I have rigs with low-end Celeron and others with better MB's and AMD 6300 CPU. Several flavors of each

What are the fastest Windows 10 x64 Radeon drivers for 290/x? Windows 10 installs 16.6 by default.

I used the second latest Crimson version. 16.6. With a custom modded BIOS and straps, I get about 176 - 178 Sol/s for a single 290x in a 3x rig.

Another great update thanks!

This is my work PC, not a dedicated rig. Small form factor Dell Optiplex 7010 (Ivy Bridge Q77 chipset), i7-3770 @ 3.4GHz, 2 x 4GB RAM dual channel PC3-12800 (800MHz) Kingston. It had two empty PCI-E slots, so I decided to stick two risers and run two cards (470 and 295). I might replace the 470 with another 295 if I find one, or a Fury or Nano to maximize hash. Free electricity. I power the two cards using a Corsair RM1000x on the side. I tried using a 3 way PCI-E x1 splitter to run more cards, but the PC wouldn't recognize the cards. I'm also mining the CPU using Kost's nheqminer (AVX) with 6 threads (~20 Sol/s), leaving me 2 threads for work stuff. While mining the CPU the clock boosts to 3.7GHz.

Have you played around with intensity? Maybe -i 4 could be overwhelming your setup?

@claymore
thanks for the new release

3x 280x toxic
2x 480 8gb (ref)
all stock settings

645.0H/s


is my psu enough for that setup?  my psu is antec hcp 1200
processor is phenom 955
my sempron wont work with this zcash

[ryantc]

two of my asus 7970 dc2 are doing 100+
my powercolor 7950s and 7970s are doing 95-99

that's fantastic 

Dude if you got the ASUS 7970 DirectCU 2 with HYNIX you should mod that beeiatch and get 140 Sol/s. Its the most stable 7970 I got running now.

Mod with my bios and run at 1100/1500, you might get lucky and be able to do 1100/1575 and get 150 Sol/s

WHAT? I am so digging this tonight,
thanks

and yes the vram is hynix on both of them
but unfortunately all powerclor are Elpida

update: my dc2 use HYNIX AFR rather than MFR, so I read Stilt's pot that AFR is properly calibrated

i got only 15% speed increase.
3x rx480 8gb.
is this normal?


tq,

I love Claymore's v6.0

7 MSI RX470s: 985 H/s
955 Watts at the wall
68 ave Watts (MSI Afterburner)
57C ave GPU Temp (MSI Afterburner)
47C CPU Temp
1500 Strap
MSI Afterburner settings: 1950 Memory Clock, 1150 Core Clock

thats high wattage u need to undervolt

Thanks to developer!!!

No.

Short info, short answer.

[dextronomous]

i have one mixed 7950 issue, one mines only 0.02 H/s while other one mines 120 H/s default settings undervolted,

using 16.11.3 latest drivers i guess in win 7.. same other card mines instantly any other coin, but in zecminer, this card will not mine
whatever i did, do i miss something,

thanks clay, great work.

Got a rig running 2x7970 (dualx and vaporx) at only 700/1375mhz,  crimson 15.12  
122h/s and hwinfo tells me 90/110W per card, stilt bios. whatever i do i can't go higher 125h/s on this rig at regular speed.
edit: if i consider only the biggest value on hwinfo, tells me 70/80w per card.
It looks like older chipset like lga775 make cards run a little slower here, even with xeon 4x3ghz inside and the same amount of ram (4G).

Another rig with asus 7970 CUII give me 145/150h/s each at full power (120/140w max for each one) on core i7 760 lga 1156, 1100/1650mhz.

Looks like my mem clock was defaulted back to 1250, once I changed that to 1500 I am now getting 320'ish per card. Looks like that was the issue, sometimes when the drivers crash, it all get set back to factory settings. Amateur move on my part, but really appreciate the help. Thanks,

I noticed that dev fee is not constant. It seems to vary between 10 and 90 seconds. Any one else?

[citronick]

Sampled v6 on my rigs:

290x at 166-168 H/s - speechless!

R9-390 at 177-180 H/s - OMG!

RX 480 at 140-142 H/s - best improvement since v5.

R9-Nano at 191-194 H/s  - OMG x 100 !

Bravo Claymore!

Those are very nice speeds. Compliments to you and Sir Claymore !!

RX470 OC 4GB - 148h/s to 150h/s modded bios and sweet spot settings

The 290x is with Stilt BIOS.

The rig has 2 x 290 and 1 x 290x - all flashed with Stilt BIOS.

After I achieved my power savings, I didn't bother with speed settings and just let it rip.

Your 290x got Hynix? Can you try running at 1100/1475 and see your results?

let me TV in later and post results

unfortunately Elpida... but managed to increase clock to 1100 from 1000. For mem clock, rig rebooted at 1475 so remained at 1250.

Increased performance nevertheless...

I am sure I can tweak it further but this rig is my test/dev rig so I will keep it at stock Stilt and enjoy the power savings.

My main rigs are 390s, Nanos and 480s - will focus on them first and attain nirvana with v6, before Claymore gets crazy again with v7 !

well this increase is 20-25%, depending on the card.  My 470/480 have gone from 125/135 to 145-155...so yeah its normal.  my 390s are up 25% though. 

[Marvell1]

So according to ethman i see 12000 h/s on my rigs but on coinmine.pl zclassic pool i only see 10k never even seen the hashrate get close to what my rigs actually say

i did not have that issue on pool.mn , could it be a latency issue or is coinmine stealing hashes ?
