Claymore's Dual Miner: Settings and statistics

[ps_jb]

Thanks to Claymore we have very powerful, stable and tunable miner. We can mine ETH, ETH-DCR and ETH-SC pairs.

I want to collect here some information on statistics on the miner and performance. If you use it for ETH only or double mining - please share your information.

My rig:

4x R9 390
Core Voltage: -100 mV
3x are overclocked to 1090 MHz (one is on stock 1015 MHz)
Memory clock: 1500
Fan: 75%
T: ~70-74C

1) Single ETH:
122 MHs

2) Dual ETH+SC:
122 MHs (ETH)
542 MHs (SC)

I'm using -dcri 9. All other numbers crash the rig

RIG 1
4x R9 390 - Using MSI AfterBurner - 4x XFX Reference Cooler Design - DCRI 30
-Core MV = -100
-Power Limit = -25
-Clock Mhz = 800
-Memory Clock Mhz - 1500
-Fan Speed = 100

ETH (Total Speed) 103 MHs
SC (Total Speed) 1540 MHs

Highest Temp observed, 80C
Watts Measured at Wall, Not tested

RIG 2
4x RX 480 - Using Wattman - 2x Gigabyte Reference Cooler Design - 2x Sapphire Reference Cooler Design - DCRI 32
-Core MV = Default
-Power Limit = +2%
-Clock Mhz = +2.5%
-Memory Clock Mhz = 2000Mhz
-Fan Speed = 82%

ETH (Total Speed) 98 MHs
SC (Total Speed) 1560 MHs

Highest Temp observed, 74C
Watts Measured at Wall, 745W

SC (Total Speed) 1540 MHs

Am I right that it is for default settings for -dcri?

[BenSF]

The DCRI setting is very important to dial in for highest profit. Here is a calculator I am working on. If you post your MH/s values at all at the various DCRI settings I show I will create a duplicate page in that google document for your rig

Appreciate it, but the topic is about real settings and real numbers. If you have some - please add.

Correct mine are default

[BenSF]

Those are settings and numbers for one of my miners, Here are my most profitable settings at the moment:

Rig 6700, 3 GPUs

1. R9 270
Core Voltage: 1.1 V
overclocked to 1120 MHz
Memory clock: 1500
DCRI -50
Fan: 100%
T: ~68-74C

Dual ETH+SC:
12.9 MHs (ETH)
322 MHs (SC)

2. R9 270
Core Voltage: 1.1 V
overclocked to 1030 MHz
Memory clock: 1500
DCRI -50
Fan: 100%
T: ~78-84C

Dual ETH+SC:
12.1 MHs (ETH)
299 MHs (SC)

3. 7850
Core Voltage: 1.25 V
overclocked to 1020 MHz
Memory clock: 1500
DCRI -50
Fan: 60%
T: ~76-82C

Dual ETH+SC:
9.8 MHs (ETH)
246 MHs (SC)

Totals
Dual ETH+SC:
34.8MHs (ETH)
869 MHs (SC)

[ps_jb]

Totals
Dual ETH+SC:
34.8MHs (ETH)
869 MHs (SC)

Impressive - ETH:SC=1:25

I'm getting the best ration of 1:4.5

[BenSF]

Totals
Dual ETH+SC:
34.8MHs (ETH)
869 MHs (SC)

Impressive - ETH:SC=1:25

I'm getting the best ration of 1:4.5

Ratio does not mean very much, I can get a ETH:SC=1:40 when I put DCRI > 80

Trick is finding the DCRI sweet spot for profit

Based on published here information I did changes in my setup settings:

Original:
4x R9 390 (3x XFX 1x PowerColor)
Core Voltage: -100 mV
3x are overclocked to 1090 MHz (one is on stock 1015 MHz)
Memory clock: 1500
Fan: 75%
T: ~70-74C

Updated:
4x R9 390
Core Voltage: -100 mV
3x are overclocked to 1050 MHz (one is on stock 1015 MHz)
Memory clock: 1500
Fan: 75%
T: ~70-74C

New stats:

Dual ETH+SC:
118 MHs (ETH)
1780 MHs (SC)

I used default settings in CDM (-dcri 30)

Did you try to tweak the GPU parameters to see effect of performance?

I only changed the intensity: ethi 16 and dcri 40

[ps_jb]

Got you!

Very good performance - thank you!

[fittsy]

Do you want people to post numbers if they don't do any undervolting, overclocking, etc?  Or no?
