What happens when you crank the mem clock up to 2ghz+ and update the bios timings?

You're not going to be able to build a mining rig right now. AMD GPUs are sold out worldwide. In the past 2 weeks I've called maybe 60 shops looking for cards in 5 different countries. I found 2 RX570s.

Cards are supposed to be back in stock in 2-4 weeks. However, with mining as profitable as it is now they will get sold out instantly. Many of the shops I called had queues for people pre-paying for video cards and lining up to get them.

I got a newegg notification that they had RX 570s in stock. I went to check it out, sure enough they had them in stock with a limit of 1 per customer. It'd take 2 weeks for me to get the card if I ordered from the US. I went to talk to someone to debate if I should buy it or not. I decided to buy it. I went back to newegg clicked 'add to cart' and the cards were already sold out.

I have windows installed on a SSD. I build the rig, boot windows, update all the vbios, shut down, plug in the ubuntu 16.04 drive, test stability / hashrate... rinse.. repeat..

It's annoying not being able to flash in linux.. But it only really adds some extra time.

If you want help send me a PM; I can help you on skype. My RX 580's are doing 27.25/600 ETH/SC at 120W -- I was only able to use the 1750 strap, the 1500 strap is unstable on my RX580s. My RX570s on the other hand are doing 30.5/300 ETH/SC with the 1500 strap at around 120W as well.

Flashed MB bios to latest, no dice
Flashed card bios back to stock, no dice
Flashed card bios back to 1500 timings, gpu underclock, mem overclock, no dice

dunno, guess i'll mine on 1 and wait for my risers to get here tomorrow then try to run them along side the other node that has my RX580s. If it still doesn't work then, guess I'll have to split the cards up.

My secret is, I pay a little more and buy DL580 G7s for $500 -- $125/mo monero cpu mining and up to 12 GPUs without a breakout board. It also comes with 4x 1200W PSUs. Just make sure to buy some ear plugs so you don't go deaf.

Is that with 1500 timings? I can only manage to get 27/600 eth/sc from my gigabyte RX580. They'll only run with the 1750 timings, crashes with the 1500. Dropping SC intensity does not take it any higher.

I flashed the firmware from the RX570 nitro to the RX570 pulse (my pulse now thinks it's a nitro). It mined a bit longer -- went from 15-30 seconds to 2-3 minutes (submitting multiple shares before crashing).

I then tried running multiple miner instances (1 instance for each card). Same, 2-3 minutes then crash.

That happens when memory overclock fails. You need to manually modify the bios because every card is different. Maybe one card will be fine at 2150mhz mem freq and another will crash at anything over 2000mhz.

I have a system i'm building now with 2x RX570s, one is a sapphire pulse the other a sapphire nitro, both 4gb. I can mine on either for hours no problem, if I put them both together the system crashes within 15 seconds of starting to mine. Maybe it's a problem with my setup, but I'm using the same setup for another build without any issues. Dunno, you could try it.

no, they aren't stock bios. I modified them to 1500, gpu underclock and mem overclock myself. (30.5Mh/s eth, 375Mh/s sc on the nitro, 27Mh/s eth, 375Mh/s sc on the pulse)

I can run either card fine by itself for hours. When they are together it crashes instantly (literally, 15-30 seconds after dag creation completes it dies).

I'm using the same setup for my gigabyte rx580s and it works fine. But, due to GPU shortages I just bought what was available instead of looking for matching cards.

The only thing I've found that actually gives some noticeable increase in hashrate is to adjust the memory timings in the vbios.

I have the same problem as you with some RX580s. Unfortunately I can only use the 1750 timing there so they cap out at 27Mh/s with 2150 mem clock. But it makes no difference even at 2000 mem clock the hashrate is the same.

Grab polaris and modify the original vbios yourself, no reason to download random roms from the net.

I have a system I just built with 1x RX 570 pulse 4GB and 1x RX 570 nitro 4gb. The system runs fine with just the pulse or nitro. If both are together it crashes (screen shows lines / hard crash). I've been playing with memclock and gpuclock settings for a few hours now thinking that was the problem. Until I realized it wasn't.

Why are they crashing? Is it the mining software that's the problem, drivers, or what? Is there a fix? I don't really want to build another system just for 1 gpu.

I'm running ubuntu 16.04 with AMDGPU-PRO-17.10

My order of 10x finally shipped. Well, at least, they printed the shipping label. Neither of my orders were given to the shipping company yet after 8 days and 6 days.

The items only take 24 hours to get to my house when using dhl, fedex, etc. I'm located in asia. I bought some other items on June 6. I had AMAZING service on those orders. I received all my items today, June 8. It took them 2 days to receive the order, ship it, and for it to be delivered. But, these extenders, wow, I'd never order from these companies again. The one is just straight up lying to me saying they gave the package to the shipping company. The status of the shipment does not say it was picked up. Also, I called and they said they haven't received the item yet. Why would they just lie to me like that?

I'm wondering if maybe the ver006c tishric are just not in stock? Then they don't want to say they don't have them for fear of losing the order. I don't know. I'm highly annoyed as I have a stack of video cards here not making money because i have no risers!

I ordered 10x tishric ver006c from 'ShenZhen TISHRIC Factory Store' on May 31st. 8 days in, no shipment, no replies after saying they were going to ship them. I cancelled the order today.

I ordered 6x tishric ver006c from 'Micro computer products' on June 2nd. 6 days in, they entered a fake tracking number, then updated the tracking number 24 hours after, and after 2 days of having issued a real tracking number still have not given the package to the shipping company.

Are all the sellers of pci-e extenders aliexpress scams or what? I ordered some other non-mining related items on June 6 and I already have them. Has anyone successfully ordered pci-extenders from aliexpress?

Already done, Just wanted to make sure you were aware of the issue. Thanks for your continued work.

Google says the file contains a virus! Looks like someone integrated claymore into some trojan software.

Anyway, I can't download the zip file..

If you can walk out your front door any time of the year and grab fruit from a tree, why would you concern yourself about storing food? Long term planning is something most low iq, resource rich, low gdp per capita countries lack. Long term planning is the basis for any rich country. If you look at the IQ map posted, most high IQ countries fall within temperate zones where long term planning is required to survive winter. These countries also tend to have the highest GDP per capita aside from a few outliers. Reminds me of Cebu, Philippines where they purchased a bunch of extended length buses for use in mass transit. The buses got here and then they realized.... Oops! The buses are too long! They can't make the turns when driving through the city streets!

Regarding corruption, it's been my experience that when there is a corrupt leader the population itself is also corrupt. These corrupt countries also tend to be in areas with no long term planning and low average IQ rankings. What the corrupt leader fails to understand when they're selling out their country is that they can make more money via corruption with long term planning and building their country up than they can by raping it. Take zimbabwae as an example, printing money to the point that they've stolen all wealth of the nation. Mugabe has been in power for 30 years, devalued the currency so that it's worthless, and systematically raped the country. If instead, he had built up his country he would have been able to steal what their current annual gdp is and no one would even notice! Their current GDP is only 14 billion annually. If he had built up his country to the scale of south africa, he could steal 14 billion annually and still have 298 billion to build up the country! His shortsightedness not only robbed him but everyone in the country.

Their RNG is broken. I've got identical hands on 2 different tables at the same time (same suits, same cards, identical...) -- MULTIPLE times. That's with less than 1000 hands played there. And for you guys who gni gni gni about probability.. There is a probability that the universe will flash out of existence or the sun will explode.. But here we are...

Also can't count the number of times there are 3 of a kind on the flop. Again, less than 1000 hands.

I certainly won't be playing there again after today. Just thought I'd try it out.

btw, sorry to resurrect a dead thread but it's #1 on google for "betcoin poker rigged"

Have you seen this guy's post history? Wow.

Someone needs their meds balanced.

I just setup a few gpu miners today trying to get back into the swing of things.

I have the units mining, but am unable to tweak them as I can't find the aticonfig/amdconfig utility anywhere. I installed the latest amdgpu-pro driver (17.10) on Ubuntu 16.04 x86_64. It's mining just fine, but the utility necessary to modify clock rates, etc is missing. Any ideas?
