Hello everybody. I have a Sapphire RX 580 4Gb, with modded BIOS (including memory timings) and overclocked until instability (1050/2020). It run under windows 10 with mining drivers, and Im having arround 25,5 Mh/s. I tried a lot of things trying to reach the "oficial" 30Mh/s that these cards are supposed to make. I even change my card for another one, but the hashes remain the same. After reading the experiences of several people with my same card and same hashes, i realized that 25 Mh/s are pretty OK for this card.

Now im thinking about building a dedicated mining rig with six Sapphire RX 580, and i wonder if the 8Gb version will reach more easily these "oficial" 30Mh/s

Thank you very much in advance for your help.

Higher hashrate depends on the memory manufacturer. Samsung best of all, Hynix/Elpida worse, Micron very bad. A good memory can keep the frequency of 2100+ which has a positive impact on hashrate.
When choosing a card should be based on the memory manufacturer.
This is not a guarantee of high hashrate, but as close as possible to him.

micron is not "very bad" but up there with samsung, the best

Higher is always better. Also not to forget that DAG size will continue to increase which means 4GB cards will not be able to mine ethereum after a certain period, for memory I heard Hynix is the most common and average performer.

Yes, sadly 4GB will stop hashing ETH in april, 2021...but somehow, I think both 4 and 8GB versions will be obsolete by then, anyway

Saphir Nitro + RX580 8G Micron 31.4 Mh/s in HiveOS.
Saphir Nitro + RX580 8G Hynix 30.7 Mh/s in HiveOS.
Saphir Nitro + RX580 8G Samsung 30.5 Mh/s in HiveOS.

On Windows you have to add ~0,5 Mh/s on my result.

all around 100W. Try different timing from Uber Mix on Samsung and no chance at all.

It looks like new Samsung on RX 580 are not the best anymore.

Well, there is no problem then if we use 4GB version till 2021, because we have money a lot twice bigger than if we use 8GB version in 2021. Cheesy

finally i found 4gb vs 8gb cards. so the conclusion is 4gb card and 8gb card will have same performance in hashrate, and that's the answer why most of miners have 4gb cards because its cheaper and they give us the same hashrate. nice thread, thank you for all members here in this thread. one important question disappear now from my head Grin

My sapphire RX580 8GB out of the box gave around 24 mh/s and after bios mod and afterburner settings around 31. This is with hynix memory. a colleague is using the 4 GB variant and he says he got approx 30 per card. So not a big difference although I can't prove it. Maybe look for a BIOS mod for your card here? https://anorak.tech/

I work RX580 4GB and 8GB RX580 keeps the same speed of 30 Mh. You have to be the same. I think you have a problem with the settings. 25-26 Mh RX580 give without any upgrades of BIOS. If you do not get to customize a BIOS you can try to find in the Internet settings.
