Who ordered the AMD Radeon VII? Lets make a list of Miners / Hashrates / Coins

[pbfarmer]

Running 6 cards on a onda riserless mobo, 1500w at the wall, 490mh/s.

1575 clock, 860mv, 950 mem phoenix miner.

Something seems to be sucking up power unnecessarily in your setup - I ran same settings but w/ my mem just a touch lower (935), and only saw 215w/card - looks like you're at 240-245 for some reason, which is generally more in-line w/ the 90Mh/s config.

My rig has 4x 4000rpm fans (or 7x 3500rpm fans), just the mobo + fans with no gpu attached is ~140w.

Even so, it's less efficient that yours. Might be my psus hitting 90%+ load, I use the Evga 1600t2.

Ah yeah - I assumed maybe a 30-50w system power draw...  Everyone seems to be running celeron systems these days (or ryzen).  So sounds like you're closer to 225w/card - more reasonable.  And yeah, I benched on an unloaded PC w/ a 1Kw platinum PSU, so possibly a touch higher on the efficiency curve.

Anyone able to turn off the red light on radeon vii ?

[solominer247]

You cant connect 6 GPU's on 1 PSU. There is no PSU on the market with 12 PCIe connectors.

EVGA has 9 connectors. You can run 4 GPU's and if you use a cable-mod (CPU to PCIe) you can run 5 GPU's.
(SuperFlower is the same as EVGA. If you dont need the 2000W, better go with EVGA!)

Seasonic Prime Gold 1300W ATX 2.4 (SSR-1300GD) has 10 connectors. With good undervolt you can run 5 Radeons. But with every energy-spike, every GPU-reset, everything which dont stay optimized will shut down that PSU.
(Corsair and CoolerMaster also have PSU's with 10 connectors. But in terms of quality and warranty they both stays way behind EVGA. Even Seasonic is not the best pick.)

So better split your load to 2 PSU's with a bit of room. If you need for example 900W for 3 GPU's, buy a 1200W or 1300W PSU. The 1300W Gold EVGA PSU's are mostly cheaper than the 1200W xxx PSU's, so the 1300W is the better choice. No need for Platinum and co, if they are only for mining.

Life saver tip: NEVER EVER use cheap 6-pin to 8-pin PCIe adapters to connect just 1 double cable from your PSU to your GPU!!! They will get very hot and if you are unlucky, you can burn down your home!
Another tip: Don't use cheap chinese server/mining PSU's. Protect your investment with quality!

Hey, yeah I had feeling connecting 6 gpus would be an issue.
My plan was to have 1 psu that can powerup as many gpus possible, so 6 cannot be done, how about 5?
Yes you are correct, the adapters will work fine for short term, but it will definitely get hot, so I won't go down that route.

I just wanted to confirm with everyone, my best option is to connect 5 gpus on 1600watts psu?
Just that with EVGA 1600G2, I was able to connect 4 gpus without an issue, it appears adding 5th gpu will be an issue as there isn't enough connectors. Although, there are now 2 x 6-pin sata ports available as I got the fans changed.

Do you think I can use 2x 6-pin sata ports to fire up the 5th gpu?

Thanks

Anyone able to turn off the red light on radeon vii ?

Not that I know of. Any lights I didn't want, I just cover it with electrical tape.

Does the tape not melt?
What kind/brand you are using?

Some generic brand. I don't think it becomes that hot, otherwise the plastic housing around the red light at the corner would melt too. Electrical tape is usually rated for higher temperature tolerance.  But I don't know if it will leave sticky stains after removed.

Yep exactly. Though they are "cheap Chinese PSU", they are around 4 times cheaper than the equivalent wattage PSU, and have more cables suited for mining use.

Though cheap isn't always best in power supply situations! The best idea if you want cheap is to use commercial server psus and breakout boards, cos they're designed for the job and cheap as chips. They are noisy tho... 

Speaking of PSUs, 2kw psu to run 8x Vega 7s per rig will be nice. There's the superflower 2000w platinum, which exists but I have no idea where to get it, and the 2200w evga platinum. No news from Evga since Jan 2018.

My Radeon VIIs run hot!  I have the mem at 1500 core 975 undervolt 875 and they still get up to 80 degrees in my shed with fans blowing on them.  Not sure I made a wise buy my hash rate for eth is down to 75.  80 - 90 make it a deal but I don't think it can run long at 85 degrees. 

That's just the hotspot temp? If so that's within spec. Mine are 70-75 degrees in MSI AB, but 85-90 hotspot temp.

No idea what temp that is, I'm using simpleos and it says temp is in the 80s.

Do you guys think this power usage is correct?  If it is that is a lot better then I assumed.

No, you have to measure on the wall. But expect about ~x1.5 from measurment in software.

Hey, I was searching around for PSUs that might be able to handle 5 or 6 GPUs.

I'm currently using Corsair HXi Series™ HX1000i for my 6x Asus GTX 1070 8GB OC rig, I realised the cables used to power up the gpus have 2x 8-pin connector but ofcourse the 1070 use only 1x 8-pin connector.
With all these 1070 gpus I've connected the power which leaves 1x 8-pin empty.

Do you guy's think I can use the same PSU;  Corsair HXi Series™ HX1000i or AX1600i to setup 5 radeon vii?

Just that after looking at my 1070 rig, there are plenty 2x 8-pin connectors to be used for 5x radeon vii setup... or am I missing something?

With HX1000i you can attach 4 GPUs, and with AX1600i 5 GPUs.

Gamemax do 2kw psu, but they are "cheap chinese" psu, and they are almost as loud as an asic (you won't believe it until you hear it).

I'm using a 1650w psu and it powers 5 radeon vii's no problem so far.

You ought to look at AX1600i, it will be enough for 5GPU and you`ll get power reserve. Even if you`d like to use HX1000i for 4 GPU - it can become a problem with electrical load.

POWER SUPPLIES (PSU) RUN BEST AT 50-70% LOAD--

Running a power supply at max load will wear it out prematurely.  And, a cheap PSU at max load can fail with a fire hazard because they may be improperly rated.  A 2000W cheap PSU on a 110V (USA) circuit would likely overload the 110V circuit and could possibly cause a house fire, not just an explodong PSU.

Thats what I wrote often before. NEVER buy cheap. You only have one life. Saving a few bucks with cheapest hardware is just stupid.

I bought cheap psus and ran them near capacity and they did fry, burned SATA connections.

[solominer247]

Hey, thanks for replies guys appreciate it very much.
Now I have an idea what psu to purchase for 4 or 6 rig setup.
It's a shame because I still have 1x 8pin connector & 2x 6pin connector "FREE" on PSU. If only these could be used to fire up another GPU, that would have been awesome!

Next part. Fans. I'm currently using : PRIZM 120MM ADDRESSABLE RGB CASE FANS - FIVE PACK for my 4x Radeon Vii rig, they are working great, no issues, I think it has auto feature where it increases RPM depending how hot the rig is running.

Do you guy's think this is a good brand? My mining rig can handle 5x 120mm fans.

What do you think?

I second this. Most US household plugs are rated for 15 amps. That's 110V * 15A = 1650W. My extension cords get scary warm at already 1250W even without tripping the fuses... So please take care, measure your consumption if you don't know it, and stay safe.

I bought cheap PSU from AliExpress and use it over 2 years. The only problem is a noise. Surely, if i had a possibility that time, i`d bought good PSU, smth loke Corsair, but it wasnt so and this PSU works right now.
