Please help with strix rx 480 8G hash rate

[TicTacKiller]

Hey guys, first time posting and just trying to get into the whole mining thing.
I have a strix rx 480 8G doing about 24mhs for ethereum and 700mhs for sia using claymore.

I keep reading of people getting at least 28 mhs by flashing with copying the 1750 strap to 2000. I've tried this but it made no difference for me, I've been playing with mem and core frequency. I can't get higher than 24 for ethereum and 720 for sia. It only goes down with different settings.
I've also been messing with the -i command for claymore and that too doesn't get me past 24mhs.

Any help would be appreciated.
Thank you!

You have to check what type of memory the card has with GPU-Z. The straps you need to copy depend on the type of memory it has. If it's Samsung memory, use the 1750 MHz timing strap for the Bios mod and 1150 MHz on the core with 2075 MHz on the memory clock should get you 28+ MH/s. Also use HWinfo to see if the card has memory errors after you overclock it.

It is Samsung, do I put the core and mem in on the boos? Something like asus you tweak?
I've done the strapping and set those numbers with gpu tweak but it's still the same. Gpu tweak will only let my core go down to 1220.. and you only copy the 1750 timing to 2000, correct?

As I have stated in other hashrate tweaking posts...
When you are trying to get the best out of your card and see how fast it can mine, you don't use dual mining.
You have to test the card with ETH only and see the maximum hashrate it can get (with bios mod, and core speed-voltage, memory speed etc)
Once you are satisfied with the results, then you jump into dual mining.
The ETH-SIA combination is dropping the ETH hashrate a lot. If you try ETH-DCR you will see higher ETH speeds.
Again... tweak,mod,push your card using 1 coin only (ETH for your card) and when you are happy, switch to whatever dual combination you are happy with.

Tested it just mining ethereum and get about 28.
Thanks for the help with that!
Still think it's strange there's. I improvemnt at all mining both..

Have tried the ubermix timing?
I hv the same card and it can do 20-30. Also check any memory error with hwinfo to ensure no over memery OC

I have not tried the ubermix timing.
And I did try hwinfo. It came up with a ton of errors, are these from a bad over clock?  If I try to start mining with hwinfo open my mining is about 7 mhs. I don't know if that means anything..

Why not try it? I had it run nicely with about -50 mc for error free with ubermix. And can reduce the cc and undervolt to reduce power used yet still at 29/580 range eth/sia with decri 20

Yes, try reducing the memory clock by 25 MHz until the card doesen't show memory errors or only a few. Sometimes it's also better to increase the memory clock with a modded memory strap Bios.

Still haven't done the ubermix,
But I managed to get 26 for eth and 800 for sia.
Gpu clock 1400
Mem clock 2075
No mem errors so far.
But I'm drawing 153 for my card only. I feel like I should be able to go less but if I lower voltage drivers crash, and if I lower gpu clock I get less hashes.

I'll try the ubermix in the am and report back.
Thank you guys a ton!

Does anyone have a link to the ubermix 3.1 download?
I found the guide but it's kinda confusing.
