Any ideas why one of my GPU's runs hotter than the others?
I have tried the followings steps (restarting after most steps): Reset WattMan Delete GPUs from Device Manager Run AMD Cleanup Tool Run both CNext setups from AMD extract folder (Radeon settings) and select Remove - I find the cleanup tool does not fully uninstall WattMan Reinstall AMD drivers Boot to safe mode and copy .sys file Boot and skip driver checks (option 7)
Run Claymore GPU 0 - 69c, 47% Fan GPU 1 - 69c, 64% Fan GPU 2 - 69c, 47% Fan
The air temp is cooler today, usually GPU 1 is well into 70%
All GPUs are flashed with this low power ROM I forced a flash onto the hot GPU but that didn't help cool its core.
WattTools/WattMan / Polaris BIOS Editor / GPU-z all show the clocks & volts are the same setup.
I cant work out what's causing one card to run hotter.
I have a MSI RX 480 8G. I flashed it with low-pwr-29MH-Boysie.rom and i get only 26MH/s and the power consumptiom from GPU-Z My settings are setx GPU_FORCE_64BIT_PTR 0 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_SINGLE_ALLOC_PERCENT 100 ethminer.exe -G -S eu1.ethpool.org:3333 -FS us1.ethpool.org:3333 -O ...... pause ....
What did i do wrong ? Did i flash the card wrong ?
For some reason 5 of my 6 cards have dropped from 29 to 26mhs today after a reboot. Was running solid 29 each for over a week. No idea why, nothing has changed other than rebooting windows

How to sign or rename or delete the atikmdag.sys file? i do not replace the original file. Win 10 pro, flash is work fine, but code 43, i change the atikfile and later cod31.

6x XFX RX 480 ref Claymore 6.4 Win 10 16.8.2
Update : rebooted and seems ok now, back to 29mhs
Haha I had this same thing happen.. it was like the bios went back to stock for one of the reboots lol
@boysie actually i've rebuild the miner and.... w10 6xrx480 driver the lastest 16.9.1 without changed the driver ati no test mode the system read the card very well ( i changed the voltage of memory to 870 otherwise is no stable ). But the atikmdag.sys why i must be changed? If i don't change the rig work.
You have modified the atikmdag.sys for read the new bios? have a digital firm also the bios? i like to know.
My problem now is the pciex 1x 16x i've buyed in china and is not good the yellow wire is too much hot 1 is changed color, now is brown, is very dangerous.... but how can i buy the good riser??? how can i recognize a good riser for buy?
if the only air they get near them is the ait from the gpu they are going to get mega hot any way, point a fan at it give it some cool air flow around all the wires. should stop and hot spots forming. but ideally you want the correct awg cables to carry the load you are asking it to, buy different ones if the one with your risers are doing that
thanks, today i verify the temperature of the wire, the night brings counsel, think the problem is the adactator for molex, the wire is a section too much reduced. today i want to read the temperature the riser, i want to see if the riser or the adactator, because some adactator i can exclude.
There are two unmodified BIOS images in zip, from Sapphire RX 480 Nitro+ 8 GB, dumped with AtiWinFlash 2.74. One of them is on default BIOS switch, other - on "silent" position.
0.65A at the wall, so in my case that's 143watt (complete system) Also measured without a gpu, so only the system and that's 0.31A or 68watt.
So basically the GPU alone consumes around 75 watt while doing 29.8Mh eth
It's been stable for over 12hrs now.
Greetings!
@Heliox Are you using the 2000 memory strap timing from the other 480 roms you shared or a new custom one?
Same strap, hence the reason why i said i would probably share it.
If it was a custom one, i wouldn't
Greetings
Hmm I can't figure out how you got the watts that low. VDDC shown is the core voltage after offset correct? When I tried a similar config mining eth-only, I was getting probably about 7.5 or so more watts in gpuz on my 480 (If I recall correctly, an then dual mining adding an addition ~7.5w)
I have so much tested the last 3 weeks with Hex Editor - ATOM BIOS reader - Forum Read messages - polaris ... unfortunately I have not managed to offset correctly to put in ROM - can I still get a few tips? possible via PM

After running the AMD installer, reboot, let windows load, then... Reboot into Safe Mode (Press F8 on startup) and copy atikmdag.sys to the ...\System32\Drivers\ folder Then reboot into the Advance Boot menu and press option 7 (Disable Driver Sigs).
You can permanently enable the Advance Boot menu with this command:
Type or cut / paste the following code into an administrative command prompt:
*** WARNING - Enabling this will stop you PC rebooting into windows automatically (e.g. if you have Auto-Updates enabled in Windows, you will need to be in front of you rig to press option 7) ***
Has anybody tried the Polaris BIOS editor? I am lost looking at it, a different beast to the old one... @Heliox, @boysie are you going to build ROMs for non-refs? I am happy to replicate your settings on my 8Gb 480 Nitros but would need hand holding

I use this ROM but i'm blocked at 26Mh/s something goes wrong but i dont know what.
Can someone help me ?

consider air flow around these wires
if the only air they get near them is the ait from the gpu they are going to get mega hot any way, point a fan at it give it some cool air flow around all the wires. should stop and hot spots forming. but ideally you want the correct awg cables to carry the load you are asking it to, buy different ones if the one with your risers are doing that

You can permanently enable the Advance Boot menu with this command:

Fellows, please advise: what will be to warranty if BIOS is changed like that? Will it stand?
