Topic: R9 280X - 15Mh/s - page 2. (Read 3012 times)
How much is 7970/ 280x doing on EXP currently? Could be more profitable for tahiti owners?
Not sure how you get such low temps but my 280X already runs at 80c without that high of a clock speed.
Those temperatures are possible at this overclock only with water cooling!or it is cold in his place
Yea, he probably lives in a cold country. I doubt someone has a custom loop with so many cards.
I've been able to squeeze a bit above 15mh but that's a lot of fans required to keep it cool
I get about 12 MH/s. I undervolt it to 0.86V and run at core/memory 800/1000MHz. My electriicty price is high.

Core 1170 will get you at that speed yeah..
Sure.
Really curious as to why you would censor your pool name. It looks like its most likely ethpool.
I'm curious as well and it's definitely ethpool. but can you share clockspeeds please?

Look Ma,... no BIOS change... 
You need to hack the bios and you'll get 18.5mh/s
This is an option but what is also already told in other topics that this is not smart because the lifetime will be shorter and you will void your warranty too.
Yes changing bios does void warranty which is already over for most 280x.

Hacking the memory timings is safe, worse case you will get hardware errors and need to revert back.
However its near impossible to get 18MH/s with these 280x currently. Best to just dual mine with them.

Perfectly possible

all my 7950/7970/280x run at 18mhs or so with no issues. Except being power hungry. 10W/1MHS
What custom bios are you using?

please tell me if it is safe to do or not. And what driver I should try. I run on win 7 64 bit with 7950 AMD gpu
I get about 17 on stock bios at 1100/1500
Sometimes due to how the memory timings table is set up, slower runs FASTER.
