Hi, for mining is the RX5 series not good power wise OR performance?
I have seen the clocks seems higher and the memory is seemingly pumpable to 2250 instead of 2100 on most RX470s?

Not sure about power?

Can an RX5 run with an RX4 card?

comments please... thanks
 
Can mix and match anything, nvidia and AMD is even possible. 570 are fine, the 470 i have can't get higher memory than my 570s, quality of card seems to have better memory, my Nitro+ gets 2100 mem bit generally you will be lucky to hit 2050 stable

If the 570 is same price as 1070, 1070 is better, but 2x570s will get around 54Mh/s and 1070 31Mh/s. Price plays a huge role

2050 on an RX470 or RX570 ?
the RX570 look to have better quality heatsinks in place.... im just scared because my friend just got a rig setup and he has 2 RX580s but they run crap and they are worse than my 2 RX470s
i do not know what bran he has and what motherboard but speeds are awful he doesnt even get 21 mega hashes on Ether for either card, its really ridiculous.
i really want want to buy a gigabyte auros or gaming card for example and it turns out to be worse than my current 2 RX470s is it possible?

If i bought myself another RX470 but the Gigabyte Gaming edition card , is that a stupid move? am i going back in time ? or do u reckon i rather get the RX570 Gigabyte Auros or Gaming card? not sure is the ASUS RX570 expedition or whatever ,is fine? BUT is the Rx470 also fine though, i know they reckon the MSI and GIGABYTE for the RX470/480 ran hot , so they said in the utube video i watched a while back


I cant do nvidia although i would not mind 1060 3GB or 1070 ...but the 1070 is ridiculous and the 6GB version of the 1060 is also ridiculous

2100 is not a realistic clock for mining 24/7. Most people run 2000 for a good mix of stability and speed.

To improve the hashrate you'll need to edit the memory timings using a bios editor. It's super easy - you simply copy the timings of a lower frequency and paste it onto the higher frequency. Most people swap the timings of 1500/1650mhz to 2000mhz. The brand really doesn't matter either. Most cards today are running hynix memory and the timings are interchangeable between cards of the same capacity (4GB/8GB).

A property bios edited RX 580 should get around 29MH at 2050MHZ currently. You can further undervolt it to 900mw and have it only consume 70w~80w.

Hi, if it is possible , i have an idea on what you mean as i have seen some videos on how they edit the straps? i think they call them straps?
Or can we just be simple and call it timings?
so like for my afterburner settings i have run the voltage to about -25 , power limit of 85, core speed to 1126 , and the memory speed to 2100.
I do this change in synch in Afterburner for my PowerColor 470 4GB and my Saphire Nitro 470 8GB. I hope this is fine? i have been mining 24/7 for a few days now.
My speeds are around 25 MH/s to 23 MH/s i am not sure if driver version and cleanliness of Windows 7 OS and claymore version make a difference.
I have seen 26 on some occasions i dont understand how it gets there.
I cant even imagine how u get 29 from a bios edit , that is like living on Mars to me,
I think i use 11.1.2 driver set and i only install the driver. I use multipool miner or nicehash, i dont know what to actually use, so i randomly switch at times.
I have tried Dashminer but according to CoinGecko it doesnt earn me much in comparison to Multipool or Nhm.
Anyways, does editing the bios make more of a difference than using MSI Afterburner, really?
Thanks for replying and reading. Looking forward to Teamview or whatever anybody can offer, many thanks
 
Memory timings. The "straps" that are being referred to are the ranges of speed. The "1500 straps" are in effect from 1500-1624, 1625 straps from 1625-1749, etc. They make an immense difference on these cards.

With how the memory timings are stepped down as you go up the straps, overclocking the memory does very little without dropping the timings. You go up in speed, but get worse timings, and it basically eliminates any benefit you get from OCing. You probably do see a *slight* boost at 2100 because the timings don't get any worse after 2000MHz. Once you mod the timings on those, you probably won't be able to maintain 2100 anymore, you'll probably be down in the 1900-2000 range, but you'll be getting somewhere in the 26-27 range pretty easily. That Nitro+ 8GB you have there likely might still handle 2000-2050 with the 1500 timings, and on that card you'll probably be seeing the 28-29 numbers. I doubt anyone sees close to 30 anymore with the current epoch/DAG.

I've had very little luck getting cards over 28 myself, but I don't have any of the Nitro+ 8GB. In fact, at the current epoch, I don't have any cards at 28. Most of mine are in the 25-26 range. I have a few 480's and reference 570's that are getting in the mid 27s with 1500 timings @ 2000MHz.

What is the power consumption like after the actual BIOS EDIT is done? I see for Ethereum i use about 95 Watts per card, this is at 1126 Core Speed and Memory Speed of 2100.

I need to re-read what you said a few times with regards to the timings, i dont think i get why it is faster when we copy the straps and why IT IS that fast when it is edited versus the Software overclock.
Anyways, sorry i am being noob , let me try read it again.
EDIT: wait, so you mean u cant really keep the 2100 setting if we are changing the Straps/Timings ? which is the CORE speed? ....

Repeat Question:
If i bought myself another RX470 the Gigabyte Gaming edition card , is that a stupid move? am i going back in time ? or do u reckon i rather get the RX570 Gigabyte Auros or Gaming card? not sure is the ASUS RX570 expedition or whatever ,is fine?

Everything he is talking about is memory. He's talking about memory clocks, timings, and straps. You edit the straps in the bios so you keep better memory timings which allow you to get a higher clock AND have better performance.
 
What software do you use to edit the BIOS memory timings?
 
I recommending reading this guide, it got me from 0%~99% very quickly.

I like to start up afterburner to set the fan speed and then close the program out, as I've found that it conflicts with the miner's polling. Also don't bother doing any undervolting or clock adjustments in afterburner, you can do in claymore.

-cvddc sets your core voltage, such as -cvddc 900 will set your vote voltage to 900mw
-clock sets your core clock. I'm solo mining Ethereum so I use 1100. I've found anything beyond that is wasting power for negligible gains.
-mclock sets your memory clock.

As you can see 28MH is very possible. With further fine tuning I could get an extra 1MH out of all my cards, but it is a tedious task as claymore doesn't order GPU by their PCIE slots and rather initialize them randomly. The custom parameters I set for GPU#1 might be applied to GPU#3 the next time I boot up.

Hi, thanks for the tips with the Claymore. For now i am okay using Afterburner i guess?
I dont know how to pass those parameters in Claymore using Nicehashminer for example.
I dont see 28 MH in your picture.

Anyways , are you saying you dont need to BIOS edit your card?
