so 16.11.5 is working well, that is good. do you use 6 oir 7 GPUs on that board?
Granted I did flash the wrong memory BIOS over one of my cards. Good deal for the two BIOS switch, like they intended you to flash one of them⌠but the whole mess is an adventure worthy of a nerdy Dummies manual. How to Make Money with A GPU Miner For Dummies.
yeah that dual switch is nice, lucky i havenât had to use it for a bad bios yet though.
gotta be careful with device IS and vender ID if flashing bios you dont do yourself
I have recovered from every mistake so far. All software BS. Had to force flash a GPU in DOS after making it unreadable in Windows.
Valid question, what are the symptoms of a bad riser?
I suppose my molex 4-pin v5s and v6s have done well enough. But what happens if one is bad?
I am running 6 so far. I assured myself it will work fine based on your videosâ vote of confidence.
i guess if a riser goes bad the GPU stops getting recognized.
I dont think ive really ever had a bad riser, swapped some before but i dont think they were actually the cause of hte problem.
I have 14 bad raisers. Here are the common problems I discovered with those.
- Fans of the GPU speed up to max speed at system startup (GPU not recognized)
- Card not recognized by Windows (GPU not recognized)
- Card found but Code 31 error
- Card found but Code 43 error
- Card found, crashes with BSOD atikmdag.sys or atikmpag.sys whenever starting to mine
- Card found, mining at just a few Sols before BSOD
- System hang up sporadically
- System sporadically reboots
- Random BSOD
- Card works perfect for a few hours before BSOD

Great info and really helpful

First time experiencing building rigs specific for mining. I have been building custom computers, servers, and netowrks for ~15 years. Mostly in the Medical Industry.
First, needed a proof of concept. Built on a MSI Z97 Gaming 5 mobo with 7 GPUs based on Cryptominedâs YouTube videos. And, it workedâŚfor only a few days. 
Had a backup mobo, Biostar TB85, which I use to build another rig. First clean boot after windows 10 updates, using the windows 16.6 Crimson drivers. Basically, set-and-forget. The uptime for that rig has been a week without reboot, Claymore v8 crash, or even driver issues. Have not had to reboot the Claymore app, nor Windows since the build. Amazing (for windows at least).
With the MSI mobo, been reading threads and trying every fix, no long-term luck. I found the PCI-E settings to Gen1, 8x/4x/4x, 64 cycles to be the most âstableâ. But, BIOS updates, driver versions, fresh different windows installs gave similar end results. TDR failures, driver failures, WattMan crashing while mining, anything and everything. Tried v2, v3, and v6 riser combinations, starting with one GPU then up to 7 and back down to 1. Even, swapped PSUs, measured and balanced wattage using a Kill-a-watt meter, no luck again. I would eliminate risers and GPUs as âred-flaggedâ when failures happened. Then, I built all the bad hardware onto the Biostar TB85, no issues. SoâŚyeah⌠Like others who are frustrated, no amount of troubleshooting could make sense of errors.
Boxed up three MSI gaming 5 mobos and sending them back for TB85s. My two weeks of troubleshooting to have an unstable rig. I was always known as the âserver reviverâ when I worked as a Tier 1 IT Helpdesk all the way through to a Network Architect. But, failed at stabilizing a new consumer-grade gaming/mining rig using that MSI mobo. Lastly, Iâve read a lot of failures and complaints about the Gaming 5, so I am giving up fully on using MSI mobos.

Have you tried windows 10? Iâm having the same problem I think thats why it call it a GAMING â5â lmao only 5 gpus can work at once
Iâve gotten all of those symptoms while trying to get this to work but I canât figure out which riser is bad, Iâve switched them all around but one at would always do 0 hashes. So I took that bad riser and switched its slot with a working riser, but then another one in a completely different slot starts doing 0 hashes and the one that wasnât working is suddenly working again. Do you still think its a problem with the riser?
Could be.
Did you update your drivers?
What Windows do you use?
Did you try to mine on Linux?
Usually I test each card/raiser for its own.
So I have 1 GPU, connect it with a raiser and see if I can mine.
Then I try the next one.
If all are working, I connect the first working card, and then add another card and try to mine with both.
If that works, I add a 3ed card, and so forth.
Iâm using XFX 4gb 470 and Iâve tried drivers 16.7.3 , 16.10.3, and 16.11.4 each time after cleaning with DDU
Using Windows 10 home x64 at the moment but have tried windows 10 pro x64 as well.
Havenât tried mining on linux as I want to mine with claymore
I did that and individually all of them are working the problem starts once I add 5 or more cards one of them will do 0 hashes
Okay, check the PCIE settings in the BIOS of your motherboard.
See if you find a setting to change the generation of PCIE to 1 or 2.
Another tip, that saved my back:
Connect all cards. Turn off the rig. Switch off the PSU(s) and wait for 30 seconds.
Then clear the BIOS with the CMOS pins on the mainboard. (consult handbook)
And then make a clean start.
The mainboard will collect device data at the first startup, and might tun itself off/on a few times.
Iâve changed PEG0 PEG1 and PEG2 to gen 1 (also tried gen2) and set configuration to 8x4x4 and latency at 96
Cleared CMOS many times as well with no luck 
Hi guys, Iâm glad to tell you, I temporarily fix the problem, but the stability needs to be test, hope you to help me improve together
My specs are:
Msi z97 gaming 5 motherboard
Intel I5 4570 CPU
8gb ddr3 ram
6X RX470 4GB Sapphire Nitro GPUâs
1X RX480 8GB Sapphire Nitro GPU
EVGA 1600W G2 PSU
Below is I met problems (Windows 10 64):
BSOD , automatic restart, most identify 6 cards, canât show the BIOS screen (Error Code A2,D6,55,26⌠ro direct into the system ), BIOS âBOARD EXPLOERâ show 7 cards but OS show 6 cards and 1 warning
Below is my repair steps, because the middle experience too many problems, so not sure the following steps for you to use:
1.Make sure you can into âBIOS setting screenâ with below settings: your primary display adapter set to PCIE and Display cable plug in cards (reference video and this card plugging in slot 2 (first 16 slot)
2.The graphics card(GPUs) is divided into two groups, one:1,2,3,4 two:2,5,6,7 reference cryptominedâs setps
3. unplugging in all the GPUs
4. try plugging in one group GPUs and start up to BIOS âBOARD EXPLORERâ screen, Observe whether the corresponding slot is work, if not work, check your device(PCI-E 1X to 16X USB Riser, graphics cards âŚ), if work try step 5,6
5. unplugging in all one group GPUs
6. try plugging in two group GPUs and start up to BIOS âBOARD EXPLORERâ screen , Observe whether the corresponding slot is work, if not work, check your device(PCI-E 1X to 16X USB Riser, graphics cards âŚ), if work go on
7. plugging in all GPUs ( one and two) and start up to BIOS âBOARD EXPLORERâ screen , Observe whether the corresponding slot is work, if not work try setp 2~7, if work prove the mainboard has known all the GPU now donât shutdown or restart, press âESCâ key into OS
Over here, âdevice managerâ should display all the GPUs
Now Iâm running âClaymoreâs V8 ZCash AMD GPU Miner for Windowsâ with 7 cards at 3 hours without problem.
I hope your problem be solved here.
glaqd you got it working, sometimes it just takes some unplugging and plugging risers back in with some restarts. once you get htem all to work, should be pretty good to go
thank you , I hope this.
My cards are showing in board explorer and in device manager but just that one card does 0 hashes did you have that problem?
