Topic: Problem with H97 Anniversary and 6x RX 480 + 1 ETH Bounty for solution (Read 1232 times)

Consider that a lot of multi rail units are sold as single rail, just because they soldered the +12V terminations togheter in the secondary stage. It's a common practice

i read about XFX 1250w. in one review they say its still multirail even being sold as singe rail. It is written in Conclusion part.

EasyRail is a marketing term for a single +12V rail, but this power supply has four +12V rails

now i have mixed feelings about it. i could get it cheap for 150€ though, but if its not any different to my Enermax Platimax 1350w it would be a fail buy

XFX ProSeries 1250 W should be OK (made by Seasonic)

- only 4 PCIE connectors for modular cables, but all PCIE cables thick AWG16, so it possible to split them without problem

Super Flower is also OK - they are OEM for EVGA PSU :-)

The rail distribution is ok, the main issue is that there's a general ignorance about the loads that a single rail can handle, forcing the psu to halt due over current protection. These are top notch psus, but as every other atx psu, they aren't designed for mining. Multi rail setup is needed to have a sort of protection layer due ocp, it's not an issue. It becomes one when you force the psu to provide more power in a rail that it's not designed to handle it. If you switch to a single rail design, it could help for sure, but you go outside the intel specification for the atx standard, which states that any rail should't go above 20A, due electrical safety measures.

If you click in my signature you'll see something about a possible candidate to remove this limit. In 3 months I hope to provide a unit that could handle up to 2400W in a single rail design, platinum certification. For the whole system, with specific cables. It will be patented, so it would require for sure more time to go in the market, but we're working on it

Btw the RX 480 are more problematic than 1070, due the lower PCIE interface power requirements.

EVGA 1300 G2 is currently not available via Amazon

Could i also take this one

it also has single Rail with 104A

Or any other brand would also be ok like Super Flower or LC? @philipma1957

As I know Enermax and LEPA PSUs have bad 12V rail distribution

Thx for all the advice lads.

Yesterday i tried the following using my Gamer PC with Asus Z97 Pro Gamer Mainboard.

I took the PSU from my mining RIG and was able to run 4 Cards on my Gaming RIG. after i plugged in the 5th it showed me that one of my GPU reached its thermal requirements to enter Valhalla and the rig was frozen. Plugged out the 5th GPU and it worked again till now...still working with 4 GPUs

I could buy a EVGA  1300 G2 @ Amazon.de for ~230€ but would like to analyse a little bit till i do it. I am in Austria.

Ill try to get the H97 back running today. It cant be that my rig PSU runs with Asus Z97 Board and refuses to work with H97 Anniversary. Smth. is badly wrong in here.

What PSUs do u have in combo with H97 Anniversary?

If its overloaded PSU, why doesnt it work even with 1 Card on H97 Anniversary board? or with 2 GPUs?

Something burned out in the PSU. It worked so your setup is fine. Now it doesn't work, something broke.

I encountered a similar situation as you. Here is what I did to overcome it. I am using 6 GTX 1070's but the method should be the same.

1. Update the firmware to the latest. I used the built in flash utility baked into the uefi. 
2. Disabled onboard audio
3. Set pci express compatibility to Gen3 and first display boot from pcie.
4. Things worked better during the setup when i kept a display connected to the 16x pcie lane. Not sure why.
5. I enabled something about power savings for acpi devices. This fixed an issues with my ssd maxing at 100% read.
6. Add 2 cards first. Get them detected, then once you add the 3rd, the motherboard will require you to use the molex power next to the pci slots for additional power, so add that.
7. I added the next 3 cards. Rebooted, detection took a while. Rebooted then added the 6th. It showed up in device manager as generic vga device. Select it and hit update drivers.

I might note that I started with a fresh install of windows 10, then later updated to the anniversary update. Once the anniversary update was done, i went into device manager and told it to update to the latest drivers by MS. If your on team red you can skip this part.

Hope this helps.

 100% sure it is your psu.  multi rail sucks

   rail 3 can do a max of 30 amps or 360 watts
  rail 4 can do a max of 30 amps or 360 watts
 rail 5 can do a max of 30 amps or 360 watts

rail 6 can do a max of 30 amps or 360 watts     if you power 6 cards on this via your risers  these cards can all pull 75 watts easy  so 6 x 75 = 450 watts    on a 360 watt rail

after a while it fades.

 download gpu -z  look  at each and every watt for the six gpus.   they will all be 75 to 110 watts  that is what they pull via  the pcie cables. gpu-z does not show your pcie well in your case your riser drain.   are you in the UK?

single rail evga 1300g2 problem solved.

I have had a lot of issues so far and what ur describing was a product of 3 different things for me.
1st solution I found to mine was the PSU is a corsair RM850 which is know to have a bad fan relay.  So it was overheating and killing so pulled that. Now I have a 120mm fan taped to it and it runs fine.
2nd solution some of the older cards dont dual mine well if at all and I think I was getting watchdog failed restarts so turned off dual mining on 7950s and 370s.
3rd solution was simply a bad stick of ram that was plaguing me for a month or 2.
I have one machine I mine on and play with sometimes testing games and Im pretty sure the i5 4690k is messed somehow. Ive replaced everything and that thing still has 2 hardware error codes.  Like 9C and A2 both mobos are MSi so that might be it too.

Hello dear lads,

since i have no ideas anymore i decided to ask here in forum, since there are a lot of pro's in mining around here. Maybe some1 had the same situation.

My H61 died after i tried to update it with the 6th RX 480 and i swapped it to a H97 Anniversary. Mining on 5 GPUs was pretty fine.

Installed all the 6 GPUs and started dual mining  ETC/SIA using Claymore miner with -ethi 16 and -dcri 28. All went fine for 20 hours and then i decided to switch the pool. Dumb idea of mine. The rig started switching off after 1 min of mining.

I plugged off all the GPU's and started mining using one. Same thing happened. 1 minute and its dead. Already tried different risers and different Driver Versions. Did a Fresh windows 10 Install. Nothing helped. Managed to get 1 Card running for 30 mins after fresh install. Eventually the rig stopped working again. But as soon as i add another one, Claymore claims to not be able to send shares to the pool and the system freezes after 5 mins of mining. Yes, i changes Virtual memory to 16GB and used all environmental variables. I can start up the system and it works fine until i start mining - the desaster starts. Also tried other miner like genoils and standard ethminer. Same picture.

I also took 2 8GB Cards and plugged them into my Gaming Rig. pass 24 hrs they are still mining fine without any hickup. Also took my mining rig PSU and plugged in into the gaming PC. also works fine. Yes i read PSU users manual and plugged in everything as described on Page 4 of the Manual.

PCIe 12v3 + 12v4 + 12v5 for GPUs and 12v6 for SATA and Molex connectors. But i highly doubt its the PSU problem.

And i was thinking. Board cant be bad, since it works normally and stops only if beeing stressed.


So it could be board or Catalyst Driver somehow not managing. But software works on my Gaming rig, so board it would be.


Maybe any1 could help me or has an idea how i could proceed further? Sry, but i can give only 1 ETH Bounty for the solution.
