@Koody@midoprince have you measured what your pulling at the wall? I'm getting 105watts (75w GPU-Z) for my rx470 nitro 8gb. You getting similar? Seems a lot better than the 130watts peeps seem to be getting with the 4gb nitro.
MSI 470, 4GB Hynix, 69% Asic quality: 27Mh ETH + 405Mh DCR. 172W @ wall, 67W GPU-z 1000/1950mhz core/mem, 875mv is set in watttool. Very silent card, 59C on the GPU, the fans sometimes stop spinning. 25C in the room. IR thermometer shows the temperature 92C on the back side of PCB near heatpipes right opposite the VRAM chips. Without undervolting, the temperature was 96C while mining. MSI 470 4GB does not have heatsink on mem chips. Overheating or it works as designed?

How do you measure 105W? GPU-Z power data is useless
@zxs If that is the MSI gaming x card you should download the msi gaming app and turn off the "zero frozr" feature. That is why the fans are stopping and making the memory too hot. I ended up returning mine because the extra cost vs other rx 470 cards didn't give any real benefit in my opinion. I also disliked not being able to use wattman to control fan speeds.
GPU 1150 and Mem 2000, both at 950mV. I think I could go lower on voltage and save more energy. Because this setting is for the card which drives the display. Temp is lower than 70 degrees, fans are at 60 to 65% usually
check your vrm temps man i have those cards and with the mem at 1925 i get 26.8 mhs and the vrm temps are crazy high like 98 degrees to 107
your ref cards wont last too long with such high vrm speeds unless you have 3rd party cooling
I'd like to put my hands on the new version with elpida memory, I assume they are at least as fast as the Hynix chips.
BTW I don't share my bios' because the detailed steps and all the settings were already discussed many times. Please take your time and do the bios mod yourself. It doesn't take more than a few minutes.
I just learned that I've been fooled by having the display on my Gigabyte and ASUS 470, that's why I had to raise the VDDCI up to 1050mV. Today I pulled the LCD and went back to 950mV and the ASUS is stable at [email protected] (and even lower). That must be also true for the GB, but I already sold it.
Hi mate, I also have problem with Asus Strix rx470 cards, I have 5 Asus rx470 cards and when I tested every single card, every card worked fine with settings: 1100/1850 and -35mV. But when I put all 5 cards in rig and start miner cards demand valtage + 50mV. I unpluged monitor,and only connected hdmi to vga adapter on card, because I cant connect via teamviewer if adapter is not connected on gpu. Do you have sugestion how to solve problem with big power comsuption with my Asus rig? Gpus temperatures are also high because of that. I using 1500 memory straps and MSI AB for overclocking.
How do you check VRM temperature? I read a few times that VRM was made to support high temperature. Like over 100 degrees
wattool shows vram temps , not sure about the temps the vram is optimal on, but all my other cards , nitros and msi have vram cooling and vram i under 85 degrees on those , ref 480s vramns also run at aroun 85 to 90
i might clock one ref 470 high as a control for lifespan testing
Hi, can somebody paste here a factory BIOS file for Sapphire RX470 Nitro 4GB with Elpida memory? I have only OC bios backup. Silent mode bios missing (vbios switch in position near the HDMI port). Card has two different bioses... Please friends help me
@Arkain Been running this for err, since whenever i posted it. But the guy i sold the vBIOS to, not all his cards take the high mem version, so had to get him a lower mem version.
1) Strapped: Took the 1500 and copied to the three settings larger than 1500. Watch this video that shows you how to strap. I did the same method: This will get you 23.5mhs per gpu
2) On the MSI Afterburner I set the Memory Clock to 2000 and the Core Clock to 1150 and press the check(Apply). This should get you the 28mhs.
3) Now I go to WattTool and look at the numbers for each gpu individually. In this case for gpu "0:Radeon (TM) RX 470 Graphics" look at the mV number in "R7" = 1150mV. I do not want this number less than 1000mV. This is just my preference. Look at the Voltage Offset. Whatever number you put in here it will be multiplied x 6.25 so, 20 x 6.25 = 125. 1150 - 125 = 1025mV(which is above 1000) so this one would be -20 and then click "Set" This gpu should now produce much lower watts.
4) Go to the next gpu and evaluate the number and make the changes in the Voltage Offset based upon the mV number in "R7." Each gpu will be different.

i put mine at 55C and the fans run a lot more

Using this one http://www.ebay.com.au/itm/Floureon-Overload-Protection-Programmable-Power-Meter-Switch-TS-1500-AU-Plug-/.
Measures 155w draw from the wall. 155w - 50w (cpu/rig) = 105watts.
I get 175W with one GPU, what are your settings?
Thank you in advance.

Here you go anyway.. https://forum.ethereum.org/discussion/comment/62553/#
Whats the difference between Elpida and Hynix memory? Is there a way to tell the card has prior to purchase?
Thanks
WattTool gives me 70 degrees for the GPU, and 88 degrees for VRM, which is ok I guess...
Furthermore, what version of the 470 gets the best performance now?
A few questions/clarifications:
1750 -> 2000 strap, correct?
2100->2250 max mem, correct?
What's your WattTool look like?
How stable is this?
Would you care yo explain what the main difference between those two memories is? Any performance diff too?
Nope, old post.

Let me know if you have more questions.
My cards seams happy with 950mV (everything else being the same)
