Hello fellow miners
![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)
I'm excited to join the mining community and have been lurking on these forums for a few weeks. I've recently decided to join the mining and would like your feedback on my setup.
I will be sure to hand out some of my newly minted bitcoins to the most helpful posters!
My setup at the moment is as follows:
PC 1: OS: Win 7 Enterprise 64-bit
MB: ASUS LGA 1155 - Z68 - PCIe 3.0 and UEFI BIOS Intel Z68 ATX DDR3 2200 LGA 1155
PSU: Antec HCP-1200 ATX Energy Star Certified Power Supply
CPU: Intel Core i5-2400S Processor 2.50 GHz 6 MB Cache Socket LGA1155
RAM: Corsair 16 GB Vengeance Blue Low Profile 1600mhz PC3-12800 240-pin Dual Channel DDR3
GPU 0:
XFX HD 7970 Core Edition 3GB DDR5 925M 2xmDP HDMI DVI PCI-E
GPU 1:
XFX HD 7970 Black Edition 3 GB 1000MHZ GDDR5 Dual Mini DisplayPort HDMI DVI PCI-E
Catalyst version 12.3.
Both GPUs are overclocked to maximum allowed by CCC: 1125 MHz core, 1575 MHz memory, max power.
PC 2: OS: BAMT
MB: AMD (?)
PSU: ANTEC|BP550 PLUS RT
CPU: AMD Phenom II X3 740
RAM: 4 GB DDR2 (?)
GPU 2:
Sapphire Radeon 6950 1GB (shader unlocked to 6970)
GPU is overclocked to maximum allowed by CCC (no BAMT overclocking is used): 800 MHz core, 1250 MHz memory, max power.
The miner used is
cgminer 2.3.1. These two PCs don't do much other than mining and occasional web browsing.
p2pool and bitcoind are running on a dedicated Debian VPS stashed away somewhere in a datacenter nearby (20ms ping, 51 TTL).
What's troubling me is that the hash rates I'm seeing are below what other posters are reporting with their less powerful cards.
* GPU 0 (
7970 Core Edition) averages
644 Mh/s at 82 degrees C.
* GPU 1 (
7970 Black Edition) averages
645 Mh/s at 90 degrees C.
* GPU 2 (
6950 unlocked to 6970) averages
306 Mh/s at 77 degrees C.
Could I be doing something wrong? I have seen comparable hash rates from older cards reported on this forum.
All screenshots are below. Any constructive criticism, feedback, and suggestions are highly appreciated and will be rewarded
