IMO, for a newbie (i'm a newbie too) there's no way to get a "quick profit" if your money is not much enough. Also, if you're going to investment with a lot of money, there's a high potential loss too. first learn about crypto investment (and the other investment) => high profit = high risk. I remember when i first invest on bitcoin around 2013-2014. I invest then i leave it like nothing happens. Then i came back when BTC was hype everywhere and got shock when i saw my btc value  Grin

Right now, the market is doing very well, it seems every coin can make a profit for you but just invest safely. Don't put all of your money in one coin. You can choose BTC, BNB, ADA (these coin is hype in my place), etc. Follow news, learn analytical, read forum, and your choice is good enough but deal with the risk if the situation is not going well / different from your predictions  Smiley Cheers, mate!

IMO, that GPU is useless at mining nowadays. You just waste your time setting up the configuration. And if you trying to mine ETH, just forget it man, to mine ETH you need at least 6GB or higher  Cheesy

just make sure you're using the lowest latency (<100ms). in my place, you'll fucked up if you're using the hotspot from smartphone. of course they give a quite good internet connection, but the latency is sucks  Roll Eyes Roll Eyes

so it depends on your own place. happy mining  Wink

I wasn't 100% sure what you meant by next line prefetch. Did you mean disabling hardware prefetch in the BIOS or setting scratchpad prefetch mode in the XMRig config.json file to 0 from 1?

Thanks, RAM timing did better than I expected, however, one has to know what one is doing to get it right.

Next line prefetch is when the CPU speculatively prefetches the next cache line to optimize sequential memory access.
It's no good for random access. It's reported as "MSR MOD" by xmrig, need to run as admin.

Xmrig is smart enough to optimize the number of threads, are you sure you were using all 32?

The best performance is usually 1 thread for every 2MB of cache. This matches up with the number
of physical cores on most mainstream CPUs, meaning hyperthreading isn't necessary or helpful.

You know what, I realise I've made a big mistake  Roll Eyes.... I've confused the MSR Mod and huge page options! I'll edit my existing post and test with huge pages off tomorrow.

I'm definitely using all 32, same with my 3950x. As you suggest though, this isn't optimal for all CPUs, my 9900k performs better using 8 threads(as opposed to 16) preferably with affinity set to 1 per physical core.

It seems to be a Ryzen thing where performance is better with all threads used.

EDIT: Added some results to original results post.

Tuned RAM timings + huge pages OFF - MSR Mod On - 16,250 h/s

Tuned RAM timings + huge pages OFF - MSR Mod OFF - 10,750 h/s

Seems you are right, enabling huge pages is the biggest performance factor here. Then RAM timings, then MSR mod.


fyi, checked my friend's rig with 3900X and run using all 32 with huge pages ON (well, RAM timings is default) produce better performance than Tuned RAM timings first. i can verify that your approach enabling the huge pages made a better performance  Wink

what mining software did you use? did you try mining using another mining software? with rx580 you'll get about 30MH/s while mine ethereum  Grin
