Altcoin strikes!!!

As LTC still continues to drop its difficulty, other altcoins are increasing their values/difficulty. Decease of LTC difficult and hashrate seem to be caused by altcoin value.

Litecoin Difficulty: 3,130
Estimated Next Difficulty: 2,508 (-19.87%)
Adjust time: After 642 Blocks, About 1.4 days
Hashrate(?): 70,138 MH/s

Dogecoin already out? No, it’s still holding near it’s highest value at the moment. Some people claim that dogecoin was 3 times more profitable compare to LTC during last week.

I don’t know why but I don’t feel like jumping between coins.

Hashing movement syndrome

Litecoin Difficulty: 3,998
Estimated Next Difficulty: 3,215 (-19.59%)
Adjust time: After 344 Blocks, About 19.4 hours
Hashrate(?): 73,372 MH/s

As hashrate of LTC continues to drop, difficult is expecting further drop. I am seeing movements of other cryptocurrencies increasing. As I mentioned before, dogecoin, lottocoin and even worldcoin is gaining hashrate by minutes. Just dogecoin itself, it has increased 3x in last a few days. Lottocoin also tripled.

Increasing your hash rate from what you already have!

This is only for the rigs under Windows setting. Sorry for Linux. =p

2 things you can do.

1. Right click on the desktop -> Screen resolution -> Change resolution to lowest possible (800 x 600)

2. In the same window, click on Advanced settings -> Monitor tab -> under Colors change the setting to High color 16 bit

Apply the settings and let the rig to run a few mins. You will see little higher than average hash rate.

My #1 rig with 3 of 290x’s average increased from 2.025 MH/s to 2.112 MH/s!
My #2 rig with 3 of XFX 7950’s average increased from 1.552 MH/s to 1.601 MH/s!

New challenge with XFX 7950 GPUs

So yes. I am on my 2nd rig. Happened to purchase XFX GPUs by posting from litecoin mining hardware comparison site. It is a reference but not 100% trustworthy. My XFX TDKC is not even near 700s as indicated in that site. Argh.. -_-;;
Well, I purchased for less anyways so I guess it is what it is.

I got 2 TDKC and 1 TDFC. 2 TDKC are currently running around 550KH/s without any changes. Weird thing is when all 3 of them are running at the same time, TDFC runs around 500 and one of TDKC runs less than 500. hum…. and TDFC runs like close 80 degree C. I don’t like that either…

I am in middle of decision. Either get rid of that TDFC and get another TDKC or try to set separate batch file and tweak it. Let’s see how it goes…

At least, I met my goal of getting 1LTC/day (currently at ~1.3 LTC/day) running with 3.5 MH/s total.

Rig #2

Finally all the parts arrived yesterday. Here are the items.

Motherboard: ASRock 970 Extreme4
CPU: Sempron 145
PSU: CoolMax 1200W
GPU: 3x FXF 7950 DD
Memory: ZSkill 4GB (2 x 2GB)

Cgminer setting

i 13
tc 8192
core 1050
memory 1500

Currently getting 525+ on each card.
I will update with better result later.

Cgminer batch file update.

-I 13 -g 2 -w 256 –lookup-gap 2 –thread-concurrency 8192 –gpu-engine 1005 –gpu-memclock 1500 –temp-target 70 –auto-fan

Running at close to 700kH/s on each card.

Gigabyte R9 280X

Finally! 3 GPUs!

~2.1MH/s!! At last!!!

2 GPUs Running!

Both running near 700 kH/s. It was 650 kH/s but when I updated cgminer to 3.7.2, speed increased.

Woot!!! 1013.6 kH/s

lol I hope the GPU isn’t burning at home!
Yes. That’s out of 1 of R9 280X GPU. Interesting.
