And the masters come to the rescue. Thank you guys for all that you do for the community Give a man a fish, and you feed him for a day, teach him to fish, and he's fed for life.

What location were you adding the offsets at? Because I don't think they can be added at A992 for cards that dont already have a programmed offset built in.
Maybe the learned folk on this thread could shed some light on how to go about adding an offset location to a bios that doesn't have one.

If you are building a pc for regular use, and want to look at mining using it, then yes these components are fine. If you are buliding a pc specifically for mining then you have selected all the wrong components.
The motherboard is the most important component, and you need one that can support multiple PCIe cards. The board you have selected can run a maximum of two, and you would need a powered riser to get the 2nd card running. See if you can get the Biostar TB250 or one of the several Z170 options mentioned in these forums.
Then for mining you need to get cards that ROI fast, so something like a 4GB RX 470. The 1050Ti is not nearly as good at crypto. You can not do a mining rig ina  regular case. You need a higher capacity power supply, assume 150W per GPU. The Intel SSD is waaay to expensive to justify its place in a mining system.
No.
Yes, a 750W PSU is enough for upto 4 GPU's. But the RX 480 4GB is poor value, the RX 470 4GB or RX 480 8GB are really the only two good options

The H81 ProBTC I remember had issues with 6 cards, but the V2 fiexs that problem. You do not need the molex connectors on the board at all, unless using unpowered Risers and non RX 470/480 cards. both of which no newbie ever uses.

1) Asrock H81M is a miniATX board, and has only two PCIe slots, so no, that is not the board that you are using. What you have could be the Asrock H81 ProBTC or Asrock H81 ProBTC V2
2) Those arent 5V plugs, they are molex power plugs which can draw upto 12V. And you should not have them plugged in when using RX 470/480 cards.
3) Again, go through the forum threads, every answer you need already exists there. Please have the patience to read through hundreds of pages and try 10's of settings, we all did it.

Yeah ... good luck running 8 GPU's on one motherboard.

What motherboard are you using?

As mentioned, its Samsung memory
I used the 1625 strap for 30+ but the result wasn't very stable for me. I currently stick to lower clocks at 1125/1950 and 28mh/s.
2025 seems low??? Wow man you must have really good chips, these are clocked at 1750 at stock so that's an OC of 275. Some cards were stable at this speed, and some werent, so I backed off to lower power stable
settings 1125/1950.

I have a curious problem on one machine that has been hashing flawlessly for almost 8 months now.

One RX 470 4Gb just dropped to 14mh/s from the regular 27mh/s. And no matter what I do it, reset BIOS, change clocks, increasing volts, DDU wipe, it just wont go back up. On a system reset it sometimes starts hashing at 18 but settles back at 14 in a few rounds.

Could it be a dying card? Has anyone ever encountered a card going bust such that its hashing continues but at a lowered rate?

Just curious, what cards are you referring to here?

I for one disagree. If the cost of setting up a 16 card system with his solution is lower than setting up two 6 and one 4 card systems like he his aiming for, I see absolutely no reason for price to be an issue.
Also I would LOVE to see a bundle that includes Finsky or Jabberwock's server PSU + nanoPSU + Cables bundled with this because this is the absolute best use case for the 2k PSU's and this is a complete quick deploy package.
Its not like you can just buy the board and run it without a power supply, and server PSU is the cheapest way to get it up and running so might as well buy them together.
In any case, bottom line is what everyone keeps saying "Quit Teasing and get Releasing"

Thank you Good sir.

Rule 1 : Do not flash a BIOS that someone uploaded because more than likely it will not be for your exact card, and it will make things worse not better. So use PBE to mod memory straps on your own bios.
Rule 2 : Do not hardcode clocks into the card untill you have tested the card thoroughly with regular OC to figure out what clocks are stable on it.
Rule 3 : Stability is far more important than peak performance, go for the settings that get you 48+ hours stable over peak perf settings.
Rule 4 : There's a gazillion guides with detail step by step tutorials on how to overclock your card, please search for them before blaming the community, this isnt school, you do not get individual attention anymore.

What do you mean "headless" implementation? As far as I can tell the headless issues are due to the motherboard bios and have nothing to do with the OS?

Kinda OT since this is a RAM Timings thread, but ill ask this anyways :

For Sapphire RX 470 4GB (Ref) cards GPU Core Volt offset is at A992 correct?
Now for the cards with Hynix memory, I find the default 04 which is 4 X 6.25 or +25mv, which seems legit.
But for the cards with Samsung memory, the value at A992 is FF which is -1 X 6.25 or -6.25mv, so something looks off.
Do different memory versions of the card have different default offset values? Or is the location different?

Any help/guidance would be appriciated.

For 5 cards? Easily. For 6? I would recommend undervolting. But I have been running 6 cards at stock speeds/volts on the RM1000X with no problems, drawing about 950W per system.

I got Quoted about $100 for it, and availability is promised by first week April (albeit in Asia, dunno about NA).

Oh quit teasing already man, I've had a boner for 8 days now


Thanks man, but out of stock before I could get em did you buy them all again?


No I bought one for $26, took forever to get to me, but it works with my H81 Pro BTC V2. Did you change PCIe to Gen1? I don't think I needed to change anything else to get it to work.
I'm actually building a 4U case that I would sell with risers/splitter motherboard/cpu/ram/ssd/PSU mounted/fixed, everything except the cards, so I wanted to be sure if I should make it a 6 or a 7 card design. The Asrock H81 increases cost because of the headless display adapter so I wanted to go with the TB85 to keep costs low.
I will be mass producing these since there is a lot of demand in my country and noone knows where to get most of the components, and I have access to a laser cutting/machining shop.

You guys are living a nerd's dream

One more question about the TB85, has anyone tried the 1x3 PCIe splitter with it? Were you able to run 7 cards with it? If someone has a TB85 and a 1X3 splitter lying around, could you please try and let us know, it would help. The ASROCK H81 Pro BTC V2 works with the splitter and you can run 7 GPU on that board, and if the TB85 can do too, minus the Asrock's headless bug, it would be the new king of mining boards.

Not on these mining boards, these are pretty much plug and play.
