MEMORY ALLOC FAILED: VirtualAlloc failed

[entak]

Since switch to randomx, I see the MEMORY ALLOC FAILED: VirtualAlloc failed for each working cpu thread. HW is the same (was working fine - without the error - before the switch), cpu config auto-generated. I googled a bit and done following:
-run miner as admin
-checked that locking pages in Local Security Policy is allowed for the account
-restarted the system, run the mining as a very first thing
-increased Virtual RAM Size (I did not find any tips how much to increase it, so tried to set it to 40GB virtual RAM on machine with 8GB physical RAM, 5 mining threads)

None of the above helped. Any tips? Or logs where can I find closer info about the issue? Thx in advance.

I have the same error, but only on machine with AMD CPU. Intel CPU does not have this error.

[entak]

Few more observations:
-I do have it on Intel CPU as well - i5 8500, AMD is Ryzen 3900X
-lowering number of mining threads has no effect - tried with single thread
-running miner under Win10

[pershoot]

I am getting this (MEMORY ALLOC FAILED: VirtualAlloc failed) on GPU (RX560) on an AMD CPU host (FX-8350).

[psychocrypt]

how do you enabled large page support. Try to run sudo sysctl -w vm.nr_hugepages=1280 maybe your number of large pages is to low!

[entak]

I am using Win OS, so through the Local Security Policy. I didn't find any option to set large pages count there ...

[diacomi]

Same problem here, but I noticed that occurs only if I use --noTest parameter.

[psychocrypt]

can you please post the output with and without --noTest

[diacomi]

Sure...

WITH --noTest

xmr-stak-rx.exe --noTest

Miner is compiled by myself with Visual Studio 2017.

[entak]

I can confirm that --noTest causes the issue, without this option, memory is allocated fine and hashrate jumps to almost double. --noTest/test outputs attached, but only extra information there is the MEMORY ALLOC error line. I am running pre-compiled binaries.

test.txt
no_test.txt

[christgelinas]

same issue on windows 10 , i do not use noTest switch.

[psychocrypt]

btw there is a new version 1.0.2 available. I think your issue is not fixed but an issue with memory pinning is fixed.

[diacomi]

@psychocrypt I can confirm that even in 1.0.2 issue is not fixed.

[psychocrypt]

thanks for the report, fixed by #2624

[Phoenix-Starlight]

It still fails for me on Windows 8.1. (Even without the flag). And that with the latest version.

[NaikDK]

Why is it mining based on CPU only?
It should mine with GPU also.
Any help is appreciated.
