Title: mining specific motherboards anyone getting better hashes manufacturs make claim Post by: speedyb on August 22, 2017, 04:51:06 PM so i was wondering if the claim that specific boards made for ming if they are actuaslly providing better hashrates or not and by how much

Which manufacturer claims a better hash rate from using their motherboard? AFAIK, what the mining motherboards claim is a higher TOTAL hash rate from being able put more cards on the same rig and a quicker ROI from not having to buy more motherboards, CPU's, RAM, hard drives and cases to have more cards.

that promises a higher hashrate Title: Re: mining specific motherboards anyone getting better hashes manufacturs make claim Post by: Vann on August 23, 2017, 12:31:09 AM i read this article http://wccftech.com/asus-b250-mining-expert-crypto-mining-motherboard/ that promises a higher hashrate You mean this graphic? http://cdn.wccftech.com/wp-content/uploads/2017/08/ASUS-B250-Mining-Expert-Motherboard_14-740x416.png That's just claiming a higher TOTAL hash rate from being able to use 19 cards on the same rig. The 407 MH/s is also actually pretty low, since it's only about 21 MH/s for each card.

The motherboard comes with on-board support for three PSU's. One for each group of PCI-E slots. Quote To support such a large number of expansion slots, ASUS has divided the slots into three groups. Each group has its own dedicated 24 Pin ATX12V power supply which makes operations stable in multi-GPU use. http://cdn.wccftech.com/wp-content/uploads/2017/08/B250-MININIG-Expert_3D-2-740x493.jpg Title: Re: mining specific motherboards anyone getting better hashes manufacturs make claim Post by: DevelopmentBank on August 23, 2017, 12:59:25 AM Speaking from experience, motherboards do not affect your hashrate. The graphic just shows a higher hashrate just because there are more GPUs. Dont let marketing get to you. Get whichever board is cheapest and get your ROI faster.

Title: Re: mining specific motherboards anyone getting better hashes manufacturs make claim Post by: coinnoob_za on August 23, 2017, 05:31:49 AM A newer PCI3 Gen 3 slot's higher bandwith would be useful for gaming only. A normal PCI1x slot has enough bandwidth already for mining. So it won't increase the card's ability to mine faster!
It's all about more slots being able to run more cards without needing additional MB,CPU and RAM. Lowering cost and quicker ROI. that's all Title: Re: mining specific motherboards anyone getting better hashes manufacturs make claim Post by: Vann on August 23, 2017, 09:39:56 AM A newer PCI3 Gen 3 slot's higher bandwith would be useful for gaming only.

It's all about more slots being able to run more cards without needing additional MB,CPU and RAM. Lowering cost and quicker ROI. that's all According to NiceHash, using a GEN 3 PCI-E lane can make a 1-2% difference in hash rate from the higher bandwidth, especially for some data transfer intensive algorithms. Quote We also checked with GPU-Z and all cards were successfully detected and linked with PCI-e v3.0, which is another bonus compared to other motherboards that usually work with 6+ cards only under PCI-e v1.1. The higher bandwidth speed may not look like an important factor, but the slower link can take 1-2% off of card's performance, especially in algorithms that are sending a lot of data from/to CPU/GPU. https://www.nicehash.com/?p=news&id=155 For most algorithms I doubt it's actually a 1 to 2% difference, but it's probably not zero either. |
