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!

Running out of 16x PCI-E risers? No problem!!!

Most of us have problem finding 16x PCI-E risers these days. eBay sells them but they are quite over priced. I saw some of them actually sold for over $30.
So, here is one way to get by.
Buy 1x PCI-E risers and trim off one side as shown in picture.

That’s it! ^^d
Make sure you trim off the right direction.

Difference of 1x and 16x is graphic processing capability. For LTC mining purpose, graphic processing is not needed. Therefore, all the extra connections of 16x are not necessary. 1x slot is enough for power and receiving data for LTC calculation.

Happy new year!

How to pick a right PSU?

I found this site from Corsair regarding PSU’s power efficiency.

To make long story short, PSU to the right (Platinum) is much better efficiency than other ones. More efficiency = less energy use = less heat = less noise = less electricity.
