@MarkAz

probably one of the best open frame seen

I've seen yours in the past and they are very nice (to be an open frame, with their pros and cons)

I am dying with ENVY on your setup... can you share what PSU you are using?

What are those orange things in HDMI Slot?
Very clean setup btw 

Here's my build:

 Blower fan cards can get away with closer spacing, as they direct the hot air AWAY from the other cards.

 Fan-type would work better with more spacing.


 A fan blowing air at the intake-side of the cards along their axis helps in either case - and if you have enough rigs stacked vertically it makes for a great place to put a room-type fan to blow LOTS of air.

 If you attach a fan to the "metal bar" that should be set to suck air OUT, as that's NOT the "intake" side but is part of the exhaust, even with fan-type cards.

Hi

That's why I needed to build something better, for a private usage.

I tend to use reliable and heavy duty components, it will pay off in the mid-term. You're right and I agree with your statement about the AMD's; in the first models it was an engineering mistake due some fulfillments about HTPC's electrical standards. They simply made a, giant, mistake, and understimated the power consumption of the chip probably (leakage)

The main issue in this sector is that the hardware solutions are adapted from the consumer market, and it's not a good thing considering the power and thermal needs of the altcoin mining scene. The ATX PSUs aren't made for such 24/7 loads, they tend to fail in the long term and haven't got many critical features that a dedicated solution (that still doesen't exist) could handle. One of my projects is to build a very capable power delivery, with dedicated VGA PSUs and another concept instead of the risers, that we are idealizing. They will be offered in the ecommerce portal of my company, when ready.

Hi mewhoyou

I'm happy for such, that price it's almost costless.

As I said I made these risers pretty much for myself, the farm I am going on to build. Given the insertion of them in some projects of mine, like the Venus Prime Unit, and future projects, I am in need of reliable, available units with a top notch quality and features. I own 70 chineese risers and unfortunately I am very disappointed about the general quality, given an high DOA and RMA ratio. There isn't a single supplier and I need to purchase them in china directly, something not compatible with my business.

They will be inserted in my solution, in a leasing project with my investors, and given some patent on them they won't be available soon.

Instead I could sell the other adapter, right in the motherboard, but it's premature to talk about prices. Let's say that money, with my business, doesen't come from that element


would you be so kind to write them in the thread in my sig? I would appreciate that, also because this isn't the proper place.

I wrote you there

I'll respond you there from now on, to such questions  

Have a good day

i tested it and in any case is still better to add fan between the gpu, without those fan no matter what space you have in summer you will suffer from high temps

Yes, they are close, that's true, but at last I have to say that it is impressive. I'd have attached PC case fans to the metal front bar, but that's because I like them so much.

It really depends on the directions the cards pulling air from and pushing air to.

In my experience high airflow between cards is worse than cards having space to pull air from (Windforce 3x).

i never had any issues with chinese riser, i still have more than 50s 1.5 years old chinese riser still running, and 72s new one installed and its been running for 7+ months

the only issue are with RX series GPU, but its not on the riser, its on PSU cable delivering power to the riser, since RX series take more wattage than previous generation. with RX480 6-pin reference or RX470 6-Pin Reference, it will eat more than 90W through the riser power on peak usually with will make Molex or SATA cable burned on PSU end point

a really nice setup

from the picture it shows a few question...

1. Why do you need such high powered PSU?

2. Why the expensive board with 7 slot but only 5 boards on each setup?

3. Pros and Con about your risers.

I would think that it would be more expensive than the chinese made once. I am getting the chinese risers for about $3.5 each. Let us know about your price and pro and con about your risers.

How much are you selling them for and are you in the US? I have been buying them from China but the shipping takes 4-5 weeks so I am looking for something a bit closer.

Due patent I cannot show you the main features, because of it will be used in our solutions.

It's brand new project, we're not using chinese schematics (In the photo I've shown the chinese, in the background you can clearly see the electric schematics.. something really different). It's conceptually similar simply due the fact that this is the common positioning of a VGA; there's a PCIE horizontal slot, 4 holes to fix the RISER, a USB interface and the connectors to power on. It's like saying that Ford it's copying Mercedes Benz due a similar car concept, or any smartphone vendor copying the other one due a thing that you put in your hand called smartphone  

These are some key elements
- the complete different power delivery, apart from a completely different pcb with copper layers and passive dissipation systems in the pcb itself. They will be very high quality, with a 2 year warranty in the EU region (*)
- much more resistant pcb (almoust double layers)
- +12V derived power, not from other methods. This system prevents potential instability, and can obtain an higher A load due more powerful components
- compatibility with molex, 6 pin and 6+2 connectors, for the maximum possible stability
- possible integration of ovp and ocp protection

They will be bundled with our other project on the motherboard, a new typologi of flexible PCIE adapter, that could be linked with other units creating a single, robust, system. They will also have a totally custom typology of heavy duty cables, for the maximum safety and A loads.

The objective is to provide a capable environment for 7x R9 290 on neoscrypt (to make you think about the potentials), with a proper power delivery and dissipation.

*we'll utilize them for our own farm btw, don't expect them to see in the market soon. I was pretty tired about the chinese ones, and theyr general lack of stability and security features, that I decided to go on my own designing one.

The riser you've shown seems surely more capable than the previous, old, one but I haven't tested them so I cannot talk for experience. How long are you using them? RMA/DOA rate?

Keep in mind that such a riser it's just useful if you've got low powered VGA's with ordinary psus. I'll have in my systems custom ones, much more complicated and potentially interesting.

That pci-e riser is indeed awesome. Can you please find link and post it here? It will decrease so much of hassle for cables
TIA

actually i am selling those... just PM me if you want

so you copy Chinese riser, and made it in italy ? isn't it just made it more expensive?
and also why still using molex powered, chinese already step ahead with PCIE powered with 12v to 5v step down regulator to prevent Molex/SATA PSU cables burned while using RX series AMD GPU

I checked lhclab.com but they dont have the one with 6 pin pci-e connector

TIA
