Hello fellow miners
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:
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.
