just 1 hour earlier, i got DAG error when mining ETH with RX570 4GB (my rig have 6 cards). i already set virtual RAM to 40 GB but it still keep telling me that DAG ERROR

Cannot allocate big buffer for DAG.
Cannot write buffer for DAG.

Any idea please?
change miner, claymore not update anymore

First of all, you have free elec
Even if those cards are doing 15Mh/s youll have good profit...

But ok

What is your config? Win ver., driver ver., etc

There is no profit in that case, profit is only after the gpu was paid off which if we think about 99% of gpus were never paid off due to the eth 15 times crash, what was the point of a 300 days roi if eth crashed 15 times, the 300 days became 300 x 15 = 4500 days = 12 years and if we really think about as every year that  gpu has a depreciation, 99% of gpus were never paid off, will never be paid off and the losers are the miners, the only winners is the people who buy eth cheap like this from miners who has no choice but to sell at this price to pay for their debs or other things like loan and who knows they thought easy  money would last forever, their easy money methodology back fired, game over for them and 99% of people who bet on mining.

Their only salvation is to hold all the eth they mined before the crash and never sell until eth price returns to $1000 plus.

hey guys, got a weird one today.

We built a new mining rig with rx 470 4GB (MSI Gaming X, Samsung memory and yeah, we're lucky enough to have free electricity), we copied the 1500 memory straps from 1500 to 2000 (like we always do), but for some odd reason we can't OC our cards memory above 1850Mhz without having the good old GPU#X got incorrect share etc... which means our cards are stuck around 27.2Mh/s.

You guys got any idea what the problem might be ? We have downvolted anything yet so our cards are definitely not power starved, I'm just a bit confused.

First of all, you have free elec

Yeah, I'm definitely not complaining about our situation (the rig belongs to me and my brother), I just thought I could squeeze a lil bit more out of our cards since I saw a lot of people having around 30mh/s with the same cards.


So we're using Windows 10 (with the latest update), the latest Claymore version as well and the latest stable AMD drivers (18.12.2). In terms of hardware we are using :

ASrock H81 Pro BTC 2.0
4GB of DDR3
a 1000W Aerocool Gold+ PSU
a Celeron G1840 CPU
and of course 6* MSI Gaming X RX 470@4GB

I managed to slightly increase the memory clock to 1860Mhz but I can't go beyond that.

win10 pro 64bit 1607 ltbs not working, only with -eres 0
win10 pro 64bit 1703 working well

cards are 470,570 and 480 4GB.

those cards are bios modded or you are using an afterburner to set the clocks?

If you don't believe it or don't get it, I don't have the time to try to convince you, sorry.

I've gotten this error before and it was basically due to not enough system memory (RAM) not Graphic memory (GDDR) or Virtual Memory.

If you got 2-4GB of memory, try adding another stick from another rig and see if it fixes it. I am assuming it will. If it doesn't work then just install Ubuntu and you shouldn't get this issue.

Solution is add to bat file command    -eres 0

Note that "-eres 0" will work for two more epochs only, so you will see the same problem in a week or two.
I prepare new version, it uses a bit less GPU memory so it will add a couple of weeks too. Anyway, for cards with 4GB or less it's a good idea to check other solutions like installing more physical RAM (if it helps) or changing OS to Windows 7 or Linux.

Please read Readme and FAQ in the first post of this thread before asking any questions, probably the answer is already there.

DAG size for ETH is 2.8 GB why is this an issue?

Because Windows 10 reserves a lot of GPU memory. Also this issue can be if not enough physical RAM is installed, Windows requires some physical RAM when GPU RAM is used, virtual memory helps but some additional physical RAM is required anyway.

It takes 18% still plenty available, 4gb cards should be ok at least a year from now

As for the system usually all rigs have 4gb RAM on MB (don't see how windows can operate normally withe less then that)

v12.0:

- zero devfee for all 2GB and 3GB cards in all operating systems.
- reduced devfee for dual mode, now it is 1%, same as for ETH-only mode.
- a bit reduced required GPU memory (both AMD and NVIDIA) so you can mine ETH a bit longer on cards that don't have enough memory.
- added version for CUDA 10.0, it is a bit faster for latest 20xx NVIDIA cards.
- a few minor bug fixes and improvements.

Linux version will be available a bit later.

It works for ETH with epoch #231
but
Does not work for ETC with epoch #238
So it will not mine too long. Maybe till #233 epoch
