New Motherboard for 6x GPU Mining Rigs from Biostar

17 Mar
2017

AsRock is without a doubt the most popular manufacturers of motherboards designed for GPU mining rigs thanks to their H81 Pro BTC model, however lately the company is having trouble providing enough motherboards for GPU miners. There have been shortages of AsRock H81 Pro BTC motherboards and the demand is pretty high with new GPU mining rigs getting built a lot once more. The H81 chipset is getting old and there haven’t been more up to date BTC motherboards getting released with a newer chipset from AsRock either and this is apparently opening up some opportunities fro other manufacturers…

Entering Biostar with their new model TB250-BTC that is apparently intended for GPU mining rigs with up to 6x video cards and to additional 4-pin Molex power connectors onboard, just like on the AsRock Pro BTC series. To our knowledge this is the first motherboard intended for 6x GPU mining rigs with an up to date chipset, based on Intel B250 and supporting socket 1151 CPUs and DDR4 memory. The motherboard even has an M.2 slot available for installing onboard SSD modules, a feature that might also be interesting for some GPU miners. The only problem with Biostar as a brand is the limited availability on many markets or the total lack of such, unlike AsRock that is available on much more markets worldwide. The Biostar TB250-BTC in not the first attempt at such a solution from the company, they previously had the Biostar TB85 motherboard that also came as an alternative to AsRock’s H81 Pro BTC, but it never got too popular since it was also hard to find on many markets and was more expensive.

It is not like there are no other interesting alternatives available to the popular AsRock H81 Pro BTC motherboard with more recent chipsets, but since they are not designed for GPU mining rigs specifically they may not all work or may need some special settings and tuning. There are some interesting motherboards with the latest generation chipsets from Intel such as B250/H270 that come with 6 PCI-E slots and at a good price, though they may need some tinkering with the BIOS settings in order to make them work properly for mining. The price is important factor when building up a GPU mining rig and you don’t normally want to spend that much on a motherboard and CPU, especially if you don’t need any of the extra features or performance provided by the more expensive solutions… lower cost means faster ROI.

If you want to take a look at these alternative offers for possible good choices for 6x GPU mining rigs take a look at the offers from AsRock, Asus and MSI with B250/H270 chipsets that do have 6x PCI-E slots. On these however you need to switch the PCI-E to Gen 2.0 or Gen 1.0 and also force the TOLUD or Top Of Lower Usable Dram setting in the BIOS to 3.5 GB manually and not leave it to Auto mode as it is by default. You may want to make sure that the BIOS of the motherboard you go for has this BIOS option available, as otherwise the operating system may have issues properly assigning resources for all 6 GPUs and they many not work.

There are a lot of comments on bitcointalk about this motherboard, not supporting more than 4 GPUs, so, be carefull, i haven’t read a single post of someone that had make it work with 5 or 6 GPUs yet.

lightman, can you provide the bitcointalk link? This particular motherboard is not yet available to buy, so that seems strange

AsRock H81 Pro BTC is still probably the best choice price wise, if you manage to get it, as there are shortages on some markets.

We have not yet been able to get the Biostar motherboard to check it out, however we don’t expect that it will have issues with 6x GPUs as it should be designed to handle them out of the box. We have already tried some B250/H270 motherboards that are not designed originally for mining rigs, but with the right BIOS settings (mentioned in the post) they do seem to work fine with six graphics cards. These however are more expensive than the AsRock H81 Pro BTC…

Guys from cryptomnesia, did you actually tried this:
to switch the PCI-E to Gen 2.0 or Gen 1.0 and also force the TOLUD to 3.5 GB?
Yes, the B250 (one I tried) has no problem finding all 6GPU. But it is definitely impossible mine, unless you are okay with 7MH per card on ETH

I am still trying to make these work, the motherboards can only seem to detect 4 GPUs atm.

There is a update bios available since march 30, we will see if our 40 motherboards purchase was good.

Does anyone know where to find the BIOS TOLUD setting on an Asrock H81 Pro BTC R2.0? I can’t find it at all – -is it called something different in the BIOS menus?? Many thanks in advance.

The Pro BTC motherboards from AsRock do not need that option to be available to the user, they are designed to work out of the box with 6x GPUs.

Well I can tell you the pro definitely does not work “out of the box” with 6 GPU’s. I’ve been fighting it all day. Enabled Mining in the BIOS. Switched to Gen1. At BEST I have gotten it to pick up 3 cards. I have watched a couple of the videos on Youtube with some guy showing Win10 recognizing 6 cards, but I can’t get it there.

I’ve gotten 6 cards to work on this mobo but it really runs stable with 5. Make sure to update to the latest biostar BIOS and enable mining mode to 6x VGA. To get the 6th card to work, it was an AMD driver trick where you swap driver files out between older and newer versions.

Hey Chris, what kind of trick about swapping? Here with the same issue, can you elaborate on that please

Yesterday I booted this mobo and it burned up PCI6-1 on the board. Not sure what was at fault. I also cant get it to post with 5 GPU.
