"only 5" :p

yup - only ...

tomorrow im looking at the new warehouse - and hoping it is suitable ...

if so - thefarm will be moved and will be running again ... the redesign ( for thegrid ) can start - and when thats complete - thefarm will be growing steadily ...

so 'only' will be a reality in the coming months ...

still looking for a mining dev to develop the miner i need ... that is a long term project though - as that will not be simple ...

#crysx

Pretty sure we're all looking for a developer to develop the miner we need... Still missing a dual miner.

however - the 6 card issue is ONLY with the 980ti cards ... it seems even the amd 280x oc / 7970 cards ( one and the same ) never had that issue either ... 6 cards and no problem ...

im sure its a bios issue - as ive seen 8 gpus in a single system run by an expensive supermicro motherboard designed ( with a large capable bios ) for such things in hpc servers ...

but i will research your suggestion - as it could also be an issue with the way the 6th 980ti card is allocated in the bios / motherboard ...

I like puzzles like this. Have you had 6 cards working in the same rig as the one currently failing with 6x 980ti?
A rig that previously worked would have the correct BIOS settings already.

I'll jump ahead assuming you have already proven your HW and SW and know where I'm leading, It may be the number
and model of card that is the problem. 980ti's have 6 GB mem so that is 36 GB to support. Just speculating, I don't know if adding RAM or swap would help.

if you're not yet fully invested in the 980ti you may want to wait a week for the 1080

I believe this is the 980Ti problem ( V 6th card ) . ( but that's for the miner. And if OS do not see 6th card - jumped riser might help.

Any time I cross a power of 2 boundary I get scared. 5 cards keeps it to 32 GiB.

you know ... its funny that i cant remember whether i DID test it on a different motherboard or not ... which would usually indicate that i didnt ...

so im going to pull one of the other motherboards from the previously working 6card 750ti systems - and replace the current motherboard for a test with the 980ti systems ...

i have it still for another few weeks before i have to give it back - so better now than never i guess ...

if anyone has successfully run 6 x 980ti ( whichever brand ) cards in one machine - i would appreciate you contacting me ...

#crysx

Your lucky I only get 2 980ti 1 970 and 1 750ti  max
Of course its a 2 core cpu.
If I had a 4 core it would work with 5 cards no more imo.
So you may need a higher core.
My 970 is a paperweight  and I'll never buy another one and I'll never buy ANTEC psu ever again.
So I had 2 problems. And the 970 clocks are at 1519 ghz  I even tried underclocking -280 ghz no luck.
Someone posted about a 2 core doing good on something ..I cant find it.. they where wrong if they put more cards in.
Ps I think you need a bigger psu

polaris vs pascal, vega will be on october, announced probably dunno about release

I'll believe this when I see it. Considering AMD is probably a few months out from launch, bit early to see leak numbers. We'll probably see a paper launch at computex though.

That seems a bit fast too, considering Polaris is supposed to be AMDs midrange lineup, it's hard to imagine it matching pace with a 1080/1070.

But what can the 1080/1070 as far as hashpower? Compared to the 980ti? thx

1080 on left and 980ti on right. Not sure how accurate and only shows it in sha256.

Link so you can can play around with it. Just click "x" on either card at top and you can change cards to compare. make sure if you change a card you go back and change the OS or the numbers will be skewed.

I ran across this.  what is wrong with this picture?
Seems wrong. Look at the 8 pin.
My 970 is still on the shelf .. it maybe the psu.

8 pin gpu and pcie 8 different ... and the 970gtx  only needs 2 6 pin on power but has 1 6 pin and 1 8 pin.
Which layout is correct? I don't know.

Don't confuse the CPU power 2x4 pin with GPU 8 pin. The PSU cables have a combined 6+2 cable,
just use the 6. The CPU cable is 4+4 and needs to be connected to the motherboard.

Don't confuse the CPU power 2x4 pin with GPU 8 pin. Plug the six pin cables into the 8 pin GPU connectors,
just make sure they keys are ligned up. And make sure you connect the CPU 4 or 8 pins to your mobo.

I know that I have 2 980ti and 1 970 gtx running.
The thing is why the difference on the 2x 8 pin  non cpu?
One says some type of voltage control.

Two extra ground wires, almost always wired to pin 7. No one really knows what they're there for.

More ground, that's it. I use 8 pin mobo to 2 x 8 pin GPU adapters for 5 x 980s on 1 PSU...

I saw Asrock released a new BIOS v2.30. Did you try flashing it already? Also disabling unnecessary things in bios like LPT, COM, audio and set PCIex to gen1 might help...

FWIW: That CPU maxes out at 16x PCIe 3.0 lanes.
http://ark.intel.com/products/80800/Intel-Celeron-Processor-G1840-2M-Cache-2_80-GHz

Depending on the motherboard implementation (specific lane design/splitting/switching), you'll run out of PCIe lanes to feed the last GPU. Any features that you disable on the BIOS, might help, especially if it has SATA, M.2, USB3.0, or any setting to force PCIe v2.0/1.0 mode. I didn't look into the motherboard specifics at all, so I'm just generally speaking in this case.
A quick enough test, would be to plug in a more capable CPU, if you happen to have one at hand... Good luck with that! (seems like nothing on the regular consumer line would do)

Very interesting I hadn't thought of PCIe lanes being the issue. But you're talking about PCIe3 which usually
only serves the x16 slots with PCIe2 serving the others. I would also expect a decent MB to be able to
configure all the equipped slots.

One quick way to confirm is to check the CPU model on the previously working 6 card rigs.

Hi crysx, guys.

I have two rigs, with the exact same motherboard and processor you have, with 6 x 750Ti working perfectly. (plus 1 rig with G3250)

16x Slot has a 16x Riser, the rest 1x powered risers.

I had to disable SATA and USB3.0 otherwise card #6 sometimes doesn't show up.

so i don't think it is an issue with lanes count in this case, it got to be driver, or it would make no sense why it works with 6 x 750Ti but not more than 5 , with newer cards.

that processor is crappy as hell, had to play with intensities sometimes to make it work, no problem with G3250 can handle anything
