Question about the Onda B250 D8P motherboard.

I got the version that has the PCI power connectors. There are 8 slots but only 6 PCIe power connectors labeled "PWR_PE1", "PWR_PE2", "PWR_PE3", "PWR_PE4", "PWR_PE5", "PWR_PE6". My guess is that they provide power to "PCIEX3, "PCIEX4", "PCIEX5", "PCIEX6", "PCIEX7 and "PCIEX8"? Also guess that slots "PCIEX_16X" and "PCIEX2" get their power from the ATX connector?

Finally, is the 8 pin connector "PWR12" for the CPU?

most likely that is correct pwr12 uses a cpu cable but you must be very carefull as I do not have that one . I have the other version.

measure your 8 pin cpu cable before you plug it in.

+ + + +
- - - - this is an eight cpu cable

not

+ + + -
- - - - this is an eight pin pcie

also if the cable measures like a cpu cable make sure you orient it correctly into the cpu input jack

Thanks. Haven't hooked them up to a meter, but did a test fit. I've got a Corsair AX1200i power supply. The cable for the CPU is the only one that will fit, it's connectors are keyed. If I try an 8 pin PCIe cable it won't go in.

I am 90 percent sure and if I were you I would check with this

https://www.amazon.com/Etekcity-MSR-R500-Multimeters-Electronic-Multimeter/dp/B01N9QW620/ref=sr_1_1_sspa?

every gpu miner should have it. or a better version of it Grin

Anybody had any luck sourcing the old 2400w server PSU recently?
Or any reliable sellers of the 1200w platinums?

check sidehack he may have 1200 watt hp's

I tried Burst out 6-8 months ago. To use a polite term, the entire system of software was a clusterf*ck, but the wallet was the worst. I managed to plot a drive well enough (just time consuming), but keeping anything connected to the network was an exercise in futility (for me at least).

thier software was junk, after taking a week to plot 9tb i could never get it to mine
the ui would say its gpu or cpu mining but never showed up on the pool

maybe it’s better now , this was four or five months ago. I still got a box of brand new 5gb drives laying around smh

Oh god... why do i have the feeling I'm going to have cases of Hard drives boxed up and sitting on a storage rack lol... getting scared now hahahaha

Should have done a proof of concept first, but alas, I jumped head first into a potentially empty pool.

I've got 12x 8tb running for 2 years on my main PC. For plotting are you using the GPU plotter, because it's way faster than CPU. It's also quite tedious to setup, you gotta count the nounces per drive, make sure the plot size is a multiple of stagger size etc.

An rx 480 8gb can plot 2 x 8tb drives in parallel without bottlenecks in 14-15hrs. Then it takes another 14-15hrs to optimize the plots to another drive.

If you are using usb splitters, limit 10 drives max per splitter. Because usb 3.0 is 5gbps, and you want to read at the max speed of 500mb/s per drive.

Imagine if you have 100 drives, gonna take forever lol

Thanks for the info guys -

Only 50 drives Kayden ... not looking forward to it now though .. but it'll give me something to do at the office... until I pull all my hair out at least lol.

Wonder if I should retask a couple 1080 Ti Rigs for plotting. Maybe even throw 30TB on each machine split it up between 10 of them ... oh man... now I need a drink!

So from what I understand the best option is to run a 4 wire cable with the appropriate receptacle for 220v ?

Note that I intend to use a 20 amp PDU for my rigs

I wouldn't say best. I'd say unnecessary. Either way the goal is to just get it done, so have him do it any way you feel best about.

exactly. the only reason for neutral is for 120.

Right, but the electrician is probably operating under the assumption that many years ago it was okay to run 3 wires for 220/240VAC circuits but these days one is encouraged, if not outright required, to run 4 wires - 2 hots, a neutral and a ground. NEMA 6-xx outlets are for loads that only use 220/240VAC; for example, larger window unit A/Cs. The old 3-wire NEMA code for 220/240V receptacles intended for heavier current circuits started with 10 (e.g. - 10-30 for dryers or 10-50 for ranges) while the current standard for 4-wire receptacles starts with 14.

In other words, I wouldn't automatically assume the electrician is an idiot, and generally speaking, it's best to run 4 wires for any new 220/240 circuits even if no 120V loads are expected.

Thanks for the explanation everyone, I think I'm the one who got confused as the electrician was first talking about a 20 amp 120v circuit but then I insisted on having a 220v circuit, so may be his neutral question was for the 120v circuit only, I'll give him a call to clarify

tell us how the burst works out i had 30tb in drives trying it out but gave up.

must be nice to be near maxed out , im only at 20 percent cap

Heck no it's not nice lol. Means I need another spot because my electric panel is only 200A which sucks balls lol.

Why did you give up on it? I haven't even tried plotting or setting up anything yet just dove in and ordered a bunch of drives. Probably getting myself into more than I can chew, but figure why not. Gives me something to do

@ magic smoker why are you trying to get video on that mobo?

are you trying for windows?

I am interested in SMOS or NVOC, but for now I want to get the rig running on Windows 10, but regardless of O/S I will need video to do the initial setup.

FWIW, I already tried plugging the monitor into each of the two GPUs currently installed with no video from either. I also tried resetting the mobo 3x because I vaguely recall seeing that as a recommendation somewhere; all to no avail.

'The right to privacy matters'

the electrical guy is a moron or a liar.

he should know that pc/computer/ power supplies are all h-h-g

but if the pdu you want to use is h-h-g-n for the wall outlet his question is meh.

Hey guys,

So I just had an electrician coming at home to quote for a 220v circuit installation
He asked me if my power supplies will require neutral, does anybody know more about this as I did a quick search and I'm still confused about it

Thanks

220 doesn't use neutral. Fire his ass now and get someone that's at least semi competent

Not necessarily... The current NEMA standard in North America is 4-wire for 220 (aka 230 or 240), and the neutral can be used for 120V loads. See, for example, NEMA 14-30 or 14-50.
