Bitnand, nvidia p104

  -  

It's lượt thích a unicorn in the mining world, so it's pretty unreal for us lớn have our hands on a number of these powerful mining-optimized GPUs


Pros:

Incrediblehash rate

Loves lớn beoverclocked

Small form factor

Excellent power efficiency

Excellent ROI

Very quiet


2017 has been a great year for miners. With Bitcoin, Ethereum & other altcoin prices shooting through the roof, many folks have sầu jumped on board the mining bandwagon. It is not uncomtháng khổng lồ hear stories where a miner gets a 2 or 3 month ROI on his equipment investment. As a result of the popularity of mining, NVIDIA quietly released a series of products dedicated lớn delivering the best mining performance.

P104-100 is effectively a 1080 with an optimized BIOS for mining operations. It uses the same 1080 Pascal GPU with 19trăng tròn CUDA cores. However, NVIDIA has decided to remove the display output function, meaning this "graphics card"is more lượt thích a dedicated mining accelerator card. This card has no HDXiaoMi MI or DVI or any output whatsoever.


The key word here is GDDR5X. If you are mining Ethereum, the memory bandwidth largely determines the mining performance of your graphics thẻ. P104-100 uses 4GB GDDR5X memory clocked at 10010MHz (default). The memory has a 256-bit bus. The high cloông xã rate combined with a wide bus means the GDDR5X memory can deliver a high bandwidth, perfect for the memory-intensiveEthash D.A.G. algorithm.

The P104-100 GPU mining thẻ is surprisingly small compared khổng lồ many modern day GPUs. This means it's easier for you to lớn build your mining rig. It's also easier to giảm giá with the rig cooling because you've sầu got all these extra cooling space. If you think cooling is a problem right now, wait til it's summer in six months. You will have sầu a real big problem by then.

Nevertheless, every single P104-100 thẻ we have tested runs surprisingly cool. Even at full hash power, we rarely see anythẻ going above sầu 60'C. On the other hvà, it's pretty common for overclocked GeForce GTX 1070 or Radeon RX580 khổng lồ shoot pass 70'C.

Claymore V10.0 miner (single-mining ETH)


This thẻ is designed for performance. Period. At mặc định factory settings before any optimization & overclocking, we are getting 34 - 35MH/s single-mining ETH using Claymore V10.0 in Ubuntu. This is a huge 35% boost compare khổng lồ a run-of-the-mill GeForce GTX 1070 performance, which is around 26MH/s at mặc định factory settings.

We followed the instructions from our trusted manufacturer và flashed an optimized BIOS designed for mining memory-intensive sầu algorithms such as Ethash. The BIOS runs a mix of new memory timings that suits this particular model's GDDR5X 4GB memory chips.

After the BIOS flash, we started a new round of overclocking khổng lồ chạy thử the limits of the P104-100 card. We found out the thẻ can run very stable at -200MHz core frequency with +1600MHz memory frequency using nvidia-settings in Linux. At the same time, we discover the power usage of each card can be capped at 135W. Achieving 40MH/s at 135W is an amazing performance with incredible power efficiency.
