Thread: Radeon R9 390X News
Post: RE: Radeon R9 390X News
| When I say "manycore CPU" I'm talking about a Xeon Phi-like accelerator, such as if Adapteva ever made the 4096-core variant of their Epiphany chip that they claim they can make.

Thread: Crypto Miner Conversion
Post: RE: Crypto Miner Conversion
| As you've identified, most mining rigs run with bare-minimum CPU and RAM, and this is far from ideal for hash cracking rigs. You can sometimes get away with an underpowered CPU, though wordlist manipu... |

Thread: Crypto Miner Conversion

Thread: GTX 970 Benchmarks
Post: RE: GTX 970 Benchmarks
| check your clocks. maybe one card is factory overclock and the other one isn't.
100 Mhz overclock is quite mild, so you likely won't have any issues running that 24/7. |

Thread: Need Help With a new build plz!
Post: RE: Need Help With a new build plz!

| 6x 7990 is not possible. 7990 is a dual-GPU card, so 6*2 = 12 GPUs. However the driver only supports 8 GPUs. Maximum possible 7990s in one system is 4. |
