Title: Re: asrock z87 fatality killer, more then 3 gpus Post by: ellave on January 03, 2014, 05:34:56 AM I have a 1150w aerocool & an antec 650w both gold...trying to get 3 gpu's from the aerocool & 2 from the antec, have managed to get 4 into windows now after updating bios...I think I may get there, albeit slowly.

I was looking at getting one of these boards for my next machine as i want to run 5 cards maybe 6 with two psu's if windows will allow it.

Title: Re: asrock z87 fatality killer, more then 3 gpus Post by: novymivo on January 20, 2014, 07:41:08 PM win 7 4 gpu max ( able to do 5 on 12.6 ccc and 2.7 sdk, but if you got r9 280x your win will see r7990 with lower hashrate -550k/hash)
win 8 5 gpu max All pcie enabled ? look on bios, try change the pcie slots, powered risers checked ? what drivers ,sdk you got ?? Title: Re: asrock z87 fatality killer, more then 3 gpus Post by: ellave on January 20, 2014, 11:15:31 PM Just to update on this, the day after my initial post this board started smoking and took out the cpu with it. Luckily all the gpus and psu survived. I returned it to the shop and got a refund.

I was able to get 5 to show in device manager but triangle on one. Novymivo care to share which order of slots are ideal for 4-5 gpus? Title: Re: asrock z87 fatality killer, more then 3 gpus Post by: gtraah on January 25, 2014, 12:08:36 PM You need to short ALL the 1 x Slots and then go to Bios and change the PCIE 16x to Gen2 , Gen 1, Gen 1
In that order and then you can plug anything into the PCie 16x slots. I was told all 7 are good to go and very stable.

Not really I understand in English ( In that order and then you can plug anything into the PCie 16x slots. I was told all 7 are good to go and very stable. That means "need to short ALL the 1 x Slots" what exactly it is necessary to make, put crossing points on all PCI-E 1x? So? http://s30.postimg.org/qhhap8w69/EFOT1_ODK.png (http://postimage.org/) Title: Re: asrock z87 fatality killer, more then 3 gpus Post by: newneo3 on February 13, 2014, 05:25:08 AM I have the same board. Use the "System Browser" under "Tools" in the UEFI setup at boot. You can see what slots have cards that are detected. I had to jump all my x1 slots as depicted above to use any cards in them. I used powered risers on the x1 slots.

newneo3 What OS are you using for 7 cards startup? Title: Re: asrock z87 fatality killer, more then 3 gpus Post by: gtraah on March 05, 2014, 01:06:23 PM Can anyone verify that all 7 pcie slots work? I've been working on this for several days. I've got jumpers and the changed pcie settings in uefi. I still get nothing but problems when I install more than 4 GPUs. I'm runing Ubuntu 13.10, and it won't even boot half the time. System browser in UEFI does recognize that I have a 5th card installed. If someone has gotten this to work, please let us know exactly what you did: Jumpers, UEFI settings, OS and drivers. I haven't been able to mine much, but help us out and I'll certainly send some coins your way! I have 7 x R9 290x GPU's On this Mobo -Use Windows 8 or 8.1 -Use LBR's modded drivers in the litecointalk forum, which allows windows to have more than 5 Cards, or else you will have 5 working and 2 with CODE 43 in Device Manager -Make sure The 1st PCI-e Slot you have a 16x - 16x Extendor -In Bios Make sure Link Speed on PCIE - 16x Are set to Gen 2, Gen 2, gen 2 I was previously told Gen 2, Gen 1 , Gen 1, But I realised Gen 2 Also Works. (I dont know what the difference is ) -MAKE SURE - you Short ALL the 1x Slots -Make sure Your computer NEVER Sleeps, And Display Never switches Off In Windows Power Options Thats what I did, And I used Powered risers on all slots, Not sure if that matters but I just did anyway Title: Re: asrock z87 fatality killer, more then 3 gpus Post by: KWH on March 05, 2014, 01:42:48 PM Can anyone verify that all 7 pcie slots work?

While I don't have this setup I do have 5 - 7950's in a machine, Win8, 990FXA-UD5. Can you post a link to the modded drivers?

Xubuntu 12.04 Jumpered all my x1 slots UEFI Settings.... didn't touch any over clock stuff, disabled everything I'm not using (ethernet, sound, SATA, etc), disabled USB 3.0 as I assume my USB wifi was causing issues. |
