Anyone has an idea about how to be sure of the memory brand from a AMD RX card ?
I may have a wrong bios flashed in mine, and I don't know how to check which kind of memory the card really is.
Does gpu-z show the real memory brand ? or does it show the memory of the flashed bios ??

If it has a dual vbios (assuming that hasn't been flashed as well). Flip the switch, boot up and see what memory it has. If no dual vbios, you may have to pull the heatsink to be 100% sure.

Correct - GPU-Z pulls the memory brand info from the BIOS, so if you flashed the wrong BIOS and it isn't a dual-BIOS version then the easiest solution by far is to reflash with the original BIOS... you did download the original from the card before flashing it, right? If not:

Even if he didn't save the original bios, he can probably find it over on techpowerup.

Thanks guys.
Yes you can easily find the original bios, but you have to know the memory brand for that ..
In my case, I'm not sure my original bios is the right one. As the gpu doesn't work properly, I think a mistake might have been made when saving and/or flashing.
That's why I asked about a solution to be sure about memory brand so I can confirm bios has not been confused with another one with different memory.

Thanks for confirming GPU-z won't help! I'll have to try something else to be sure.

Does your particular RX not have a dual bios?  If it's a Sapphire, it should have dual bios.  As someone else said, move the tiny black slider to the opposite position, check your memory type, then after you have done that, switch the slider back and use ATIFlash to flash the correct bios.

Ah the joy of having 27 nvidia 1080ti's

and only 1 rx560

fuck bios flashing.

Proud to say never did a one.

Eh, it's not so hard.  You just have to back up the original and then be careful to apply a compatible new one.
The advantage is this:  going from 700 H/s on an RX 480 8 GB to a very steady 860 H/s.

Agreed 100%

My group's AMD farm was tweaked for ETH (2015-2016) and it was a bloody nightmare that BIOS flashing.

If I could turn back time, I would have used 1060s and 1070s any day.

No BIOS flashing needed, impressive MHs, watts and temps well under controlled.

That premium on NVIDIA cards vs AMD - is worth it.

Apart from Vega cards, all cards acquired since last year were all NVIDIA.

@R0mi - I had to flash over 300 x GPUs (470s, 480s) - it was no picnic.
I also had to do a crash course Linux because the farm went 100% SMOS and ditched Windoze.
Thanks to kind souls out there, I managed to write a script that will flash batches of GPUs at a time, in Linux.

[tadeus1]

True, true.
I started with Nvidia (most of my GPUs) then due to gpu shortages switched to few ATI RX570s and I regret going that path.  Endless hours bios modding, power efficiency tweaking, dreadful ATI drivers, etc.
Even though the expense was less for the ATIs and eventually I made them work very good, they consume more electricity than the NVIDIAs for similar hashrate for the algos I use.
My next GPUs would definetely be Nvidia. 3 clicks with the mouse and your are all set.


vg54dett: Look for the memory chip if you can see through the cooler or below or above it. Depends on the GPU of course.
What is your GPU?  Tell us if you don't mind.

nuff GPUs... lets talk Asics.

My group has a sizable Scrypt and X11 ASICS farm hosted overseas.

With dwindling revenues in Scrypt and X11 algos, especially X11, we had to make a decision on what to do with the farm.

The farm is about 70% ROI, consisting of Innosilicon A4s, Bitmain L3+s and D3s.

Total hash power around 11 GHs Scrypt and 350 GHs X11.

Keep or sell off the farm?

Conclusion: Keep the farm alive for special project, as long as the power stays cheap (ie. cheap Canada hydro power)

Special project:

Acquire LTC, ETC, RDD, XVG and VTC for long term.

Using prohashing.com, a Scrypt and X11 multi-algo pool, we portioned a fixed % for these 5 coins (to be auto-exchanged)

There are a number of other coins that prohashing can auto-exchange to, depending on your preference.

Too bad prohashing.com only supports Scrypt and X11 mining.

For more algos & coin pools, MPH is a good choice but it allows only 1 coin type to auto exchange.

Well, if you change your mind let me know. I have a few rigs in Labrador and just sent 2 more A7 rigs there today ....and am looking for a couple Scrypt rigs. I wouldn't have any issue buying rigs hosted by either Cryptoboreas or Great North Data.

Given up on the D3s.... but the L3+ and A4s are worth keeping... new Asics are very expensive now, and the scalpers are making things worse.

It's a Sapphire rx470 reference, with blower. So, no dual bios, and no way to see inside without removing the blower

Disagree 100%.
Yes, my RX 570's were a pain to flash and setup... A YEAR AGO. But that's because of a bunch of different issues. Immature drivers. Immature mobo BIOS. Little knowledge about the best mem timings to use... You guys need to put things into perspective here. Back then you were able to extract 29Mh/s out of a GPU that cost less than $200 BECAUSE AMD ALLOWED YOU TO DO IT. Try to get that out of any nVidia card at that price!

Today, not only are all driver and bios issues sorted, timings are widely available. You can get your AMD rig flashed, up and mining in no time. If there is stock building up in RX570/580 at less than $350 they are an extremely compelling option.

Remember  we are allowed to disagree.
If you made money  your way cool.
and this I will say amd cards have dropped in price  finding them at 300-350 is now possible.

Finding a new  nvidia 1080 ti under 900 = hard

If you know anyone that is good at computer software have them write you a sell-bot...

I use my old Gunbot 3 exchange subscription to auto sell, i mine all my coins directly except for when nicehash was more profitable (recently removed them temp), but i have the Gunbot setup in Panic Sell mode, so every 60 seconds it checks the exchange for any coins on the pairs i mine directly, if it sees any it sell them within seconds of showing on the exchange. I offset the profit factor in awesome miner based on how easy it is to transfer the coins...

example, dgb since the coins are very cheap, i get a lot per block while mining, so i literally transfer after each block and it eats up about 1% of the profits from all the transfers paying the transfer fees, so i offset the profit factor in awesome miner so it only basis that coin to mine based on 99% of the current profit price... others like zec, which i get much less and the transfers eat up more of the profits, i only after xx amount accumulated i have it transfered to the exchange for sell off, so i tracked this and i found i was loosing between 3-7% in value on the coins between market changes and delay to send coins for selloff, so i set the profit margin at 93%.....

Then recently i went a step further and tracked the wattage each coin was drawing from the wall on the rigs, i found a 12% different between the most efficient coin vs the least efficient coin, so i setup the power tracking portion of profit switching on awesome miner, i found after setting this up... i went from mining mostly skein and blake2s to now most of my coins fall under phi and xevan after taking into account the power draw

Im with you on this bud, ever since i went all watercooled on every gpu i mine with except my test rig... my average hashrate increase across all the rigs already nearly payed for all the work it took to convert them all to water... the new waterpump setup im running is showing to be super stable and i was actually able to add a variac to reduce the waterpump down to about 40% of the output it was running at previously and still have plenty of overflow flooding the supply side of the system.... temps down here have been up to 89-90F during the peak of the day already and my gpu temps are still peaking at 57c on the loop

Dont get me wrong - the AMD farm is still alive and well - well optimised, undervolted and stable with the custom BIOS. Still the workhorse in the farm doing UBQ and XMR. Apart from some GPUs with failing fans, the farm is steady as a rock.

However.... If I were to do everything again, I will choose NVIDIA purely for speed to deployment, and probably worth more after sales because the BIOS are intact and seems components better quality. Its just preference my friend.
