Hi guys, I'm planning to change my mobo that has only 6 pcie slots and i have 12 gpus connected with the splitters, but i notice some gpus are not working at full hashrate and i think that is due to the splitters. So i would buy another mobo, with at least 12 pcie slots to directly connect my gpus. Can you reccommend me some top notch mobo for mining that has at least 12 slots, but if there are some mobos with more slots, it's good anyway, maybe 15 or 18. Thanks in advance.

The ones that aren't at full hash rate, they're lot LHR cards by any chance are they?

I have 2 6800 XT of which one works at 62,5mhs and the other works at 55,2mhs. They are identical, so the issue is in the splitter for sure.

Proper test is run just 1 card one the mobo and check its rate. then run the other card on the mobo check its rate. both should do close to 62 it is the only way to be sure there is not a card issue. if you determine it is a card issue you deal with it differently than if it is a mobo issue. My guess is the mobo or the splitter is the problem. But if it is a card you will go nuts if you buy a new mobo and a new splitter and get same shitty results I asked the mods to move this to altcoins

If i buy a new mobo with at least 12 pcie slots, i don't have to buy other splitters too. The real goal of this mobo change, is just to completely remove the splitters from my rig. But in general, i think that with a new top quality mobo that supports 12 gpus natively, the general managing of my gpus, should be way better, compared to the management of my current mobo that uses two 1to4-splitters. Also from a system stability and reliability point of view, this change should be an improvement. Don't you think? Moreover, i can use my current mobo, to build another smaller 6 gpus rig, to expand my mining farm, but this is a different topic. Thanks however!

If you want to mine without problems, buy a proven inexpensive motherboard and raisers, choose a model to mine without raisers. https://aliexpress.ru/popular/b75-motherboard-mining.htmlThe fewer adapters you use, the fewer problems.

Just because they are same 6800XT doesn't mean the same OC settings will work for all cards, 62MH is possible on all the 6800XT but you need to try different combinations of overclocking, we have different of memory type that's why, eg Hynix, Micron Samsung.

Good advice 👍, the B75 has 12 PCIe slots available and the good thing is offers on Aliexpress starts from 57$ with a CPU, 12risers and CPU heatsink, just make your choice, before graphic cards lose value PC components lose values faster. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2F1Zxwjc1.jpeg&t=665&c=RhwGvKnRm7gjjw)

But i was writing the same thing: if i use a 12 pcie slots mobo with 12 risers and so without any splitter, this shouldn't be better and with fewer potential issues than using the same 12 gpus with a 6 pcie slots mobo and with 2 1to4pcie splitters? In summary, using the splitters to connect more gpus than the available pcie slots in a mobo, is just the same as connecting fewer gpus, in the same number of the available pcie slots in the same mobo and so without using any splitter?

This is why I keep telling people to always go for higher-end mobo for mining.
You can never tell when you are up for more GPU, you are simply saving yourself for any future spending.
12 gpu slots motherboards aren't even that costly there is no good reason not to but them over 6 gpu motherboards.
The moment you buy your first three graphic cards you will want to add more gpu in a matter of months.

There are many motherboards with 12 PCie space this days and they are not that costly like some said, you can find them for 70$ to 100$ if you shop through Alibaba and AliExpress websites, here are the most popular mobo with 12x gpu space 1. B250C MOBO 2. B75 MOBO 3. B250 AI MOBO 4. B250P MOBO 5. TISHRIC B250 12P MOBO Happy Mining.

Splitters don't always work with every motherboard, I have a splitter here that only works with a single GPU out of four space available, tried the splitter in two different motherboards and get the exact same result so I just give up, if you are into mining for the long term it makes more sense to buy a motherboard with extra PCIe slots available just in case.

I do not buy a motherboard for 12 video cards for only one reason - I need to solve the problem with cooling. I use open cases, and the 5th video card in a row is already hot, and the sixth already has problems. And motherboards for 6 graphics cards are available in stock at all stores.

So you mean that splitting my rig into 2 ones, is my safest choice in the long term?

So much depends on the mining room. https://www.amazon.com/dp/B07CDW87RR/ref=sspa_dk_detail_2?this rack at amazon is 4 feet wide 5 shelves and 5 foot 5 high. it can fit multiple rigs and allows for good spacing. For most garages this is as much as you would ever need and can easy peasy do 5 six or 5 eight card rigs. only you know if you need this much. also having 2 six card rigs spaced for cooling allows testing 2 softwares etc

I would also add that mining mobos aren't very useful for anything else and 6 cards rigs don't need 2 PSUs. Whether that matters to you depends on the size of your farm. The number of rigs complicates management as well as the size of the rigs. A larger farm is easier to manage with fewer, but larger, rigs. Finding the right balance is a bit of an art.
If you're only building a 12 card farm I suggest 2 rigs. If 100 cards, larger rigs would be preferable.

I agree, troubleshooting is much easier to target the problem i.e. from overclocking or a bad riser. I suggest a B250 with a EVGA SuperNOVA Platinum 1600watt PSU or 2x EVGA Gold 600 W imho. In addition, power overload causes the wires to melt the insulation that can then lead to a fire.
