Some Tips for the Latest Claymore’s ZCash AMD GPU Miner v12.0

13 Feb

Claymore has released yet another update for his ZCash AMD GPU Miner that brings some more extra performance boost for mining Cash (ZEC), however the latest v12.0 of the miner does come some new specifics. The latest version v12.0 comes with improved speeds: about 405 H/s on stock 390X, 450 H/s on stock Nano, 290 H/s on stock 280X, 295 H/s on stock RX480. It however has issues working with higher intensity on older GPUs with less VRAM such as 280X where the intensity may need to be lowered. Also on mining rigs with 6x GPUs where you may have just 4GB of system memory you may observe trouble running the miner properly on all 6 cards at maximum performance unless you have set at least 20GB SWAP file. Lowering the intensity manually may help, but it is much eaŃ€ier to just increase the amount of space allocated for the swap file…

Can you add how you increase the space allocated for the swap file? I have 6x 280x rigs and just lowered my intensity, so this could really help me out.

280X need to run at lower intensity not because of lack of system memory, but because of less video memory, the requirements for the GPU video memory have increased in the latest release and higher intensity can be used for video cards with 4GB VRAM or more.

I specified -i 8 for highest intensity for my 8GB Sapphire Nitro+ RX 470 cards but the log says intensity 6 was selected. Anyone else see this happen to them? It does say ASM was selected as the mining algorithm which is the most efficient. I’m getting about 280 H/s on my stock cards.
