rx470 MSI 4Gb @jet @29mh/s

peg-slot @5A  Shocked
GDDR5 voltage is 1500mV

the powr seem very high, i think better to use low power rom then undervolt vddc to 980, my friend can reach 28mhs with under 80watt powerdraw in gpu z

For everybody with the MSI 470 4GB, the best I can do is 28.5MH/s using the 2000Mhz strap. Can't go any higher.







How much power is it pulling at the card and at the wall?  That is a pretty good number from the 470.  What ram manufacturer are they using on that card? 

Hynix Ram

Uses about 150Watts



This is a cute looking card. Anyone has feedback with the fans? Are they reliable? Btw thank you for sharing the memory manufacturer. Did you try the card with XMR or another Algo? And without bothering you too much why did you chose it over a 1060? thanks in advance.

I just bought 2 of these, the fans are fine, I'm getting 22 Mh per card ETH only.

Cheaper and it has 3 year warranty so the fans don't need to be reliable.

Got a 4 card RX470 Sapphire Nitro rig built this week:

Asrock Anniversary Z97 Mobo with 8gb RAM, 120gb SSD, 1000W Corsair HX1000 PSU.
x4 RX470 Sapphire Nitro 8gb GPUs on USB risers.
Windows 7.
AMD driver version 16.300.0.0
Claymore’s miner, mining ETH only.

All running stock speeds without any over clocking at 98Mh/s (24.5Mh/s per card).

Mobo only (no monitor allowed for) - using 80 watts.
Add 3 cards and it sucks in 600W … and a fourth card and it’s up to just over 800W.

The power draw looks too high to me, thought the cards should be about 150W each.

 Huh Any ideas to reduce the power usage on this would be welcome …




Right out of the gate install Trixx and hit the power tune slider and take it down until you start to affect the hash rate and apply and save it.  That will knock a chunk out of the power consumption.  Then go back and start tweaking the vbios.

MSI 470 4GB

Strap at 2000Mhz @ 950mV (BIOS mod and Windows signature hack)

Core at 1145Mhz (Reduced with Wattman)
Voltage fixed at 900mV (Reduced with WattTool)

Running at 28.3MH/s consuming exactly 136Watts with a Gold rated PSU. So 4.8W/MHS.

I physically disconnected one of the 470s to measure the power usage, its real and total consumption is exactly 136Watts.

Mod your bios to change your straps and lower your core clock and voltage.

Here are some discoveries regarding the PCIe slot power draw. When using the 2000Mhz strap at 950mV. The slot uses about 55 Watts whether you are ETH solo, ETH+SIA dual mining, or even Undervolted Engine Core. The slot ALWAYS uses the same amount of power. Only the power draw from the 8 Pin connector changes. I think the memory is powered by the slot and indepedant of anything else. So don't connect these to a SATA connector or use more than 1 connected to a molex connector.

Interesting.  I have one card on a sata to molex connector (a better one than those that comes with usb risers).  I was skeptical and monitored it for heat, but its pretty cool.  The only other sata to molex I have is on a 390, and that one gets relatively warm.  So far so good but I dont push those cards and they are very undervolted.  SATA is rated for 1.5amps per connector I think and 4.5amps per wire ?  Wondering why my stuff hasn't exploded yet.

I' guessing it would be better to chain the molex cable - a molex connector is over 100w, maybe up to 13amps.  Now i'm guessing I could put 2 470s on the same molex wire to the psu, and that would be better than using a molex to sata adaptor ?  so one cable:           470(molex)----470(molex)--------empty(molex)------PSU

I use the USB riser for the 390, it is not hot. Maybe that is because I use the undervoltage, the total power draw on the card is only 160W on the wall.

if anyone has tried this method ? modding Rx 470 4gb and stable at 28mhs at dualmining.
boysie mod his rom look at this pict :

I notice that the speed is at 1945mhz ... where i am stuck with the stock speed.. anyway to release it?

I was thinking about building a 470 rig but i am not that impressed by the hashrate mining ETH.
 
no, it's hashrate is not too impressive 20-25mgh, check my broadcasting:

My small rig: 2 GPUs: AMD R9 390 and new RX470 give 50mgh on average: https://www.youtube.com/watch?v=cXJxZ6V3gI4&list=PLEZgknqdd1nB9GJRh5JaNZjxP4hIetVfo&index=5

Hope it helps and interesting

Yeah thanks. I flashed the cards with new timings and copied over the .sys file and used wattman to make adjustments. I can confirm 3 days mining with Sapphire  RX470 OC 4GB at 25.5Mhs each. Total draw at the wall for whole setup with 3 of these cards is 470w with monitor off. 500w with monitor on :-) Best settings is core 1050/820 and GPU 1850/850. This is dual mining ETH and SIA.

dual mining does use more electricity and generates more heat.  your eth should be actually a bit higher with dual mining, due to reasons I wont go into detail, but in claymore's thread it is explained somewhere.  hmm the timings, well I just replaced the higher mhz timings with the lower one, so if it was 555xxxxxx and 777xxxxx, i put 555xxxx in 777xxxx place.  if you have a bios switch and mess it up its not a problem, if you dont, i am not responsible Smiley
