Hashrate RX 470

[MikeBuzz]

I have 4x XFX Radeon RX 470 4GB RS Black Edition RX-470P4LDB6

From 3 of the card i am getting around 29Mhs, but the 4th card struggles to get 28Mhs, it turns out there are 2 versions of the card, A.2 and B.2, A.2 is Hynix and B.2 is Elpida

The Elpida run fine at 1250/2000

You can share your bios rom for xfx 470 Hynix and Elpida memory, have those and those, thanks

Yep 1500

here is a link to the bios, both orignal and modded

https://www.dropbox.com/sh/br4awa75ltg7tfy/AAAjF2Qk66OYlP1ntyLWDDbza?dl=0

i have removed the card that has the hynix memory as it seems to cause the system to be very unstable, but running the 3 cards with Elpida memory its been running for 12hrs with out issue average speed 86.41 according to nicehash

Top one is Hynix



Have flashed the Hynix back to standard BIOS now, will try and get this card swapped out, as seems to just generate memory errors even with no strap change

Sapphire RX 470 4GB (Ref style) Memory Variants and their Max Hash Rates :

I only buy this card because of its reference style design, HSF making contact with and cooling memory, and its low price.
So far I have 81 of these cards, and run them all at ultra low power settings 1025/1785 @825/825 90W(at the wall, including PSU inefficiency).
I tweak timings till I get 25.5Mh/s per card at the above settings, and each of the variants can achieve this so they are all the same to me.

1: Hynix Memory Variant (43 cards average)
Cards with Serial Number beginning with A163XXXXX have Hynix memory, easy to mod, custom straps publicly available, perform ok, unstable at high clocks
Stock : 1216/1750 - 21.4Mh/s (solo mining ETH)
Max : 1150/1890 - 28.1Mh/s (dual mining ETH and Pasc with dcri 9)

2: Elpida Memory Variant (7 cards average)
Cards with Serial Number beginning with A1643XXXXX have Elpida memory, hard to mod, some custom Bios available, perform well
Stock : 1216/1750 - 22.3Mh/s (solo mining ETH)
Max : 1150/1940 - 28.9Mh/s (dual mining ETH and Pasc with dcri 9)

3: Samsung Memory Variant (31 cards average)
Cards with Serial Number beginning with A1640XXXXX or A1644XXXX have Samsung memory, easy to mod, perform the best, stable at high clocks
Stock : 1216/1750 - 24.6Mh/s (solo mining ETH)
Max : 1150/2025 - 30.2Mh/s (dual mining ETH and Pasc with dcri 9)

At this point, can you show serial Number for Samsung Memory? Thank you.

Mentioned above already. I would still recommend always checking in GPUz before you begin modding the card.

I love my Hynix cards - excellent on both Eth and XMR.

If looking to buy some more RX 470 which are the best at the moment, the Sapphire Nitro+ or the Sapphire ref card, there is about a £20 difference, or is there something better??

these XFX are starting to annoy me, have gone from a stable system to one that now hangs after a few hours or can run for 12hrs then hang, has just flashed all cards back to standard and will see if the issue comes back

I like the Nitro+ over ref-looking.

Great, have just order 2x Nitro+ 470 8gb 11256-02-20G for a good price

opsssssssss.you are right....
my mistake!!!

sorry

Hello,

does anyone have idea how to determine memory manufacturer running Ubuntu?

Bios have multiple options in drop down menu in PolarisBIOSEditor....

Thanks

Hi, i have

RX 470 Nitro+ 8GB (samsung) bios mod strap 1625 timing, -96mv, core 1050, mem 2050 = 74w @ 28,4Mh/s ETH

Its very efficient

The actual power from the wall should be more than 100W. Your value is from the GPUZ.

hm surprising,  on th wall 296w = 2x 470 8GB + i5-3450 @ 2core/1,6GHz 0,871v

I looked into hwinfo, there are several values. GPU core power, GPU chip power, GPU power in Vram.

So it could be -

GPU chip power GPU + VRM power in

70 + 49 = 119 * 2 = 238 watts Rx

119w per 1 RX 470 ist real?

-----

298-238 = 60 watts mother board + cpu, perhaps even minus 10% efficiency power supply.
