Thread: New build with Titan X
Post: RE: New build with Titan X
| If you're using reference design cards with the RM41300-FS81 then you can safely stack 4 GPUs on top of each other without a gap in between each. Temps will be a little bit high, but should still be w... |

Thread: Nvida fan control of 2nd card
Post: RE: Nvida fan control of 2nd card
| You need to generate a proper xorg.conf to fake having a monitor attached.

Thread: R9 380 (Older R9 285) for build?
Post: RE: R9 380 (Older R9 285) for build?
| There's really no good reason to use an AMD GPU in a new build. Should be able to find a GTX 970 for around the same price. |

Thread: R9 380 (Older R9 285) for build?
Post: RE: R9 380 (Older R9 285) for build?
| They are different architectures so you cannot directly compare the number of shaders. For example, the GTX 970 has 1664 cores and capable of 3.5 TFLOPS, while the R9 290X has 2816 cores and capable o... |

| 32GB total, or 32GB free? And how many Titan X do you have?
cuMemAllocHost is returning CUDA_ERROR_OUT_OF_MEMORY so you're definitely running out of host memory at some point. |

Thread: Best video hard choice
Post: RE: Best video hard choice
| 970 is faster than the 390, and roughly the same speed as the 390X.
If you plan to stack two cards then you absolutely do not want axial fans, so the ACX 2.0 is not the way to go, nor is the 390. Y... |

Thread: Single CPU vs Dual CPU & Hashcat
Post: RE: Single CPU vs Dual CPU & Hashcat
| In this specific instance the single X5690 will be faster.
E5430 - quad core, no HT
X5690 - six core with HT
That's 8 threads @ 2.66 Ghz vs 12 threads @ 3.46 ~ 3.73 Ghz. |
