Topic: Built first Mining Rig using Asus B250 mining expert Motherboard on Open Air Rig (Read 318 times)

I'm having some problems with the B250.  I'm running three rigs with the B250, each rig is running 11 AMD 580 cards.  I can't get past 18Mh/s on each of the cards. 

My system is Windows 10 64bit.  The latest Claymore.
I tried modifying the bios but it won't let me do anything.  Even something as simple as using Afterburner will only show me the temp I can't make adjustments to it.  I can't install Wattman. 

I tried using other drivers but it will only let me use Crimson drivers and software.  In the Crimson I set it for compute away from graphics and still nothing good. 

I tried AtwinFlash and it won't take. 

Hardware
Asus b250
8gb ram
1 1300W power supply
1 1000w power supply
11 MSI Armor RX580
1 i5 processor
250gb Samsung Solid State HD

Any Help would be greatly appreciated

I cound't either.  Guess its all html.  Appreciate the info and will give the compute option a try with the newer driver.

Can't figure out how to post images in the forum. 

That is good info.  I wasn't aware of the compute mode option and will give it a try and report back my results.

Why not just switch the newest Adrenaline drivers from Graphics mode to Compute mode?  I get the same effect as running the blockchain drivers without having to uninstall and reinstall different/older drivers. Just curious because I see most people use the dedicated blockchain drivers but the newest drivers have the option to use either.

Wattman increases the speed from 26.x to 29.x by lowering the voltage and increasing the clock speed.  No issues so far.  Settings don't hold if you reboot the PC though.  I haven't figured out what bios setting to mod for those settings yet that equal to what Wattman changes

I used the default Bios Mining options on the ASUS motherboard and haven't had any issues so far on both systems I built.

So far so good and stable on Claymore mining software.

1st miner - 8 total video cards - been running for approx 2 weeks - 10 days good run time counting for experimenting.

2nd miner - added 2 more video cards today for a total of 7 - been running since 12-22-2017

Thank mjamell for sharing, I dont even know about the AMD Wattman setting. Typically I finish my setup at your step 3.
Have you tested the stability for step 4 with 24/7 in at least 1 week of mining?

Did you use Mining Bios Option ?
I tried 8 RX 580 on it using Bios Mining option but I finally disable it. Enable 4G + Gen 3 for Linux (like normal set)

1. Tested Cards as factory on Claymore 10.x on Windows 10 64bit
2. Modified Bios Timing Straps - AtiwinFlash and Polaris Bios editor and Pixel Clock Patcher
3. Uninstalled latest AMD video drivers and installed AMD BlockChain video driver - major speed increase here.
4. Used AMD Wattman to lower the frequence to -10 and bump up the clock speed to 2150 on each individual card. - reduced temperature and increased hashrate.

I will post some pictures of the custom open air frame I built and the components if anyone is interested in seeing this rig setup.  Picked up the materials at Lowe's and made the frame from wood.
