Litecoin mining with undervolting Asus R9 290x - 4GD5

[jirkalada]

Hi,
anyone has experience with undervolting Asus R9 290x - 4GD5.

It is possible to undervolt with Asus GPU Tweak application, but it seems to me that this program does this only for one card (I have 4 in my rig).

My max. hasrate is 890 khps but cards draw 389W each (total W consumption / [number of 290x cards]).

Anyone has setting for good hasrate with lower consumption?

Any update to this?

Hi fella. You've got bigger problems to worry about than undervolting if you're only pulling 890 kH out of 290x's. I have the 290 non x, and am getting a steady 893 for over a week solid right now with zero restarts to my operation.

On that note, GPU tweak is trash. You need to install afterburner and use that.

He probably has the Elpida ram r9 290x, like me.   I look forward to the day getting this thing beyond 885kh.  With two r9 290x, I pull at the wall 650ish watts.  I used AB, 0 powertune and lowered the voltage by -37

Hynix is far superior for hashing

I'm not sure if I've ever heard of 290x's getting sub-900 max hashes before tonight even w/ the non hynix ram, and I've done a whole lot of reading and messing w/ configs for the 290 non x's. Either way, have you taken a look at this link?

It's what I used as a base to get my 290's where they're at. I'm sorry that I can't vouch for this person's recommendation about the 290x's, but can definitely vouch for the recommendation about the 290 config.

I have pointed a few people w/ 290x's at that link before and they've had positive results. Of course these were brand new miners so they didn't have a chance to tune their rigs fully yet.
