I used Polaris Bios Editor to change BIOS, and AtiWinFlash to flash it. I'm able to successfully flash it and verify after reboot by saving to disk via GPU-Z and re-opening in Polaris editor to verify values.
I use TRIXX to undervolt, and to overclock GPU & Mem clocks. I can also successfully verify the clocks in GPU-Z.
After changing GPU clock I can see slight changes in hash rate, but changing memory speed has no effect what's so ever..
At the moment I'm using 16.9.2 drivers.
Any help would be appreciated.
Topic: Memory Clock Not Effecting ETH Hash Rate (Read 348 times)
What tool you used for Bios mod , probably your bios have two types of memory and the modding tool is modifying the wrong one so it is having zero effect .
What ATI driver version, and what tool you use to increase memory speed?
So for some reason my memory clock has absolutely no effect on my ETH hash rate.
Everywhere I read, everyone is saying that its the memory clock that has most impact on ETH hash rate, but I see absolutely no increase between 1750 -> 2150.
The only way I'm able to bump up the hash rate is increasing GPU clock, its a very slight bump, going from 1050 -> 1125 gives me a bump of 0.75 MH.
Using Sapphire RX 470's 4GB Nitro (Non +).
I tried modded bios, 1500, 1425 & even 1375 straps. I'm undervolting GPU, but not touching the memory voltage.
But no matter what I do memory clock has no effect on hash rate.
What could be wrong and any way to fix this? Do I need to overvolt GPU memory?
