Those boards are hard to find. Try the biostar tb85

Using Claymore's XMR miner, it auto detects 1024 hash per GPU for my RX480.

My best performing card for XMR is the R9-290X at 1372 hash per card and R9-390 at 12xx hash per card.

I'm trying to a find an ASRock H97 Anniversary LGA 1150 in Canada, if anyone has a source with a normal price.

Thanks

No I was not mining XMR yet so no testing.

I went with a build similar to this and it turned out pretty rigged.  Able to pick it up from any leg without feeling the slightest bit loose, but it is a bit heavy with everything in place. 

Will try and post a pic soon.

hey phil when you had the 460 did you test on out on xmr to see the hash rates of it?

Yes I have an i3-6100t and a g4500  running the two four card rigs  they basically get 92-96mh doing  eth coin  they use about 590-610 watts the i3-6100t  and about 615-630 watts the g4500

if you run eth only  on the biostar z170 board   the best cpu is a g4400t    then the i3-6100t   both of these will allow the four card rig to do 590-610 watts  at about 95mh on eth only.

   I like the four card build due to its size.  If I were to do all my rigs over again I would have all 4 card mobos from biostar and sit them on a wooden rack I have. I would also change out my storm door on the back of my garage as It would allow more air flow if it were a full size screen.

   I had 3 two card mobos with cpus left over from mining btc and ltc back in 2012.  so I started mining eth with them.  I had 2 three card mobos from builds of gamers for friends. (they were rma replacements)   so I had 5 boards with 3 cpus for zero cost to start and I had 3 hd7970 gpus all idle.  So my beginnings with eth coin  were based on that 'free' gear.

thats a negative on pci only slots. they need to be pciE

sorry if thats already answered, im blowing through threads right now as im in that dang real life thing..

something you should be aware of: some mobos will disable some pcie slots when others are in use. so just because it has 6 slots doesnt mean you can always use them all at the same time. not sure about the one you linked to however.

best thing is doing what youre doing.. check in build threads and see what others have made work.

The H81 BTC Pro is probably the most popular for mining and has been around since the Litecoin mining days.
All my mining builds are with this board - cheap and good. You do need to have PCI risers though which I hate...

IMHO, my favourite config is 4 or 5 GPUs because it takes on less power draw and this way avoid having to get an expensive PSU. With 4-5 GPUs, something like a750/800 watts PSUs like EVGA-G2s is more affordable.

Thank Cintronik... I am currently using MinerGate, which at the very least, seems to be a good way to learn for noobs like myself. It has a very easy to use GUI with no coding or command line stuff that I dont quite get at this point. Not only does it allow the same #of cores to dedicate option, but also provides a GPU intensity throttle as well.  I may get into some of the other CPU/GPU mining options down the road if they offer better hash rates though, so good to hear about them.

oh btw, I did find what looks like a pretty good resource for MoBo's that accept 4-6 GPUs:

Granted, this is about 5 months old, but at least at that time, there were not really any 1151 MoBo's would do more than 5 GPUs. several ASRock options for 4 or 5 (which i will be looking into) but would have to reconsider 1150 if I really want to have the capability of 6.

Just ordered this combo the other day Phil - from Newegg.

I decided to build separate XMR rigs with RX470-4GBs - and keep my existing ETH rigs running on its own.

This time no SSDs and risers, just 128GB M2 boot drive will do fine.

Thanks for the tips.

I hope to put them in a decent chassis -- hope I have better luck compared to your unfortunate attempt previously.

Will post when completed.

My Sapphire RX480 x 6 runs on Celeron 1840 (2 cores) just fine - ASrock H81, 8GB RAM, 120GB SSD, Win10 and Crimson 16.9.1 - this rig can mine XMR and ETH using Claymore very well. Btw, the RX480 has ROM mod 29MHs below 100w per GPU courtesy of Heliox, without messing with Wattman or Afterburner. Running very well and stable.

If you mine XMR using CPU, you can use Joblo's Cryptonight miner and there is a special swicth that enables you to use how many cores to mine XMR - that way, you still could do some other work with the spare core.

So, on the CPU side, I am under the impression that a good one (like 6800k or 5820k) can mine almost as much XMR as 1 of the 470s i have coming.  If you look at the list below, it shows CPUs like a very old i5-3520m providing a hash rate of 438 K/s and a i5-3570k getting 344.  I have not seen benchmarks for any 5th or 6th gen 800k series like I mentioned above but would assume that since they are much more advanced than those 3rd gen CPUs on this list, they should be able to mine XMR in the 500-700 M/s range. If i had to pay the full $400+ for these it might not be worthwhile but since I can get them for $200, it seemed to be a good idea... if they will indeed get around 600.

Now that I looked up that g4500 CPU Phil mentioned though, I see that it only pulls 65W as compared to the 140W of the ones I was considering, so that obviously should be factored in.

I'm curious... have you or are you able to ascertain what hash rate you are able to get solely from that g4500 mining XMR?  I would like to try to figure out the difference to do an ROI calc but again, I'm also kind of speculating on the capabilities of the 800k's so might be tough. But, even my VERY old i7-2600k is averaging about 100 H/s, so seems as though a current version could get 5-6x that.

I guess my other question would be, if I am dedicated to building a rig capable of 5-6 GPUs, could that g4500 even handle that?  Do you have it running any of your 4-card rigs?

Get the biostar z170 and make two card rig then go,to four cards.

Use a low cost g4400 or g4500 cpu

same question. No need mining, the cheapest cpu is what you want.

Why must you use the i7 6800 CPU?

OK thanks... back to the drawing board I guess lol. I will do a search in this forum to try to find some other recommendations.  I think most of the ones recommended for 6 cards in this thread are either out of stock or LGA-1150, so will see what else I can find, but any recommendations are welcome... looking for LGA-1151 to support up to 6 GPU's, preferably around $100 or so.

And another noob-ish question... I'm assuming that all PCI slots need to be Express, not standard (old) PCI.  I have seen some nice looking Mobos with 6- PCI slots but 3 of them are standard PCI.

Thanks again...

Nothing to look for, just from people stating that certain board can't do more than 4 gpus for some reason.

thanks for that heads-up xlee!  So, what designation exactly do i need to look for in the Mobo title/specs to know if it will accept more than 4 GPUs?  I thought since this one has 6 PCIe slots that it would work to plug 4 GPUs into them (what else would they be used for, audio cards?)

A few other ASRock boards I looked at also are Z170 but a couple are H97 and then one higher end Z97.  Are these the labels that indicate how many GPU's it can take?

I know i need to look for LGA-1151 since that is the CPU i decided on, and 6 total PCIe slots... but what other easy way is there to tell what boards will support 6 cards?

Thanks!
