Sapphire Radeon R9 290 Tri-X OC

[...]

On the R9 290, usually memclocks between 1250 and 1499 will decrease performance.  If you can't hit 1499/1500 memclock, then use 1250.

not on hynix cards mate..r9 290 with elpidia and with hynix meories are 2 completly different cards and require complety different tunning..what You said is completly right for elpidia models. If I go 1499 or 1501 my hashrate drops a lot, but not on hynix one's.

I have both elpidia and hynix cards...

I'm currently using 947/1250 for a R9 290 Tri-x for 825 KHash.

Kind of disappointed, I could have got a 280X almost at this hash rate.

Although it's been around 25 degrees in Auckland (NZ) lately, even wiath fan at 75% my GPU temp gets to around 82.

Why did you down clocked it?

some Sapphire R9 290 Tri-X won't run stable if you run it with 1000/1300 when using SCRYPT algorithm. Seems like a fault in some batches.

My cards are running 875 with a power consumption of 315 watts.

Ratio 2.77.

Cany anyone beat this?


It would be nice if anyone could include the power consumption as well.
I'm not intrested in 950 khs with a power consumption of 450.

Thanks

Downclock mem from 1350 to 1250, you will see better performance. I have yet to see any R9 290 that hash scrypt well at anything other then 1250 or 1499/1500 mem clock, and I personally run 24 of these cards, and have tuned many more for others.

Basically, R9 290s either 'take the mem overclock' aka handle 1499 mem, or they don't. After you determine that, find your max stable engine by increasing to 1020, and then decreasing or increasing in increments of 10. Only decide an engine clock is stable after 24hr.

I will try that. Mine right now is 1000 / 1420. 883 khs at intensity 20.

Good rate but i have seen better ones try to play with voltage...

[nvandertill]

I tried moving my mem clocks up to 1500 but ended up putting back to 1350. I read on LTCtalk that 1250 is better. Will be trying when I have a chance. Right now I get 880 with 1000/1350. I want to see 900-950 stable.

Anyone tried a different BIOS?

I flashed a few, then when I reboot into windows CGMiner swaps my cards around, and detects the R9 290 in slot 1 and my 7870 in slot 0...

Flash back original BIOS and it goes back to normal.

Any ideas?

My fans still run at a very high intensity even after shutting down sgminer; with the above configuration. Anyone know what I can do to resolve this? Thanks!

Use MSI afterburner then click reset.

Haha that's what I'm doing. I thought therw was a way for it to auto-reset things as I exit the miner? No?

As long as you quit with Q rather then by pushing the X on the titlebar, the stock fan speeds should be restored.

Hello,

I tried everything, but it seems that my two Sapphire Tri-X R9 290 couldn't be underclocked below the default values - GPU Core - 1000 MHz, Memory - 1300 Mhz - I set for example GPU core at 947 and Memory at 1250, but when I look in GPU-Z (latest version) I see that the default values are shown and the change haven't been applied. I tried setting this in CGMiner 3.7.2, SGMiner and with Afterburner. I can set a higher clocks (like 1080/1500, or 1060/1499), but then the driver keeps failing and only the second GPU is actually working (at around 950 MH/s) and the first one isn't mining at all.

For the moment they are both stable in the same time only at default clocks (1000/1300) where I get 882KH/s per GPU.
I've tried to tick the jumpers on the cards, but the system haven't even start, so I've reverted back the change.

I am using 8 GB ram, Win7x64, Catalyst v13.12. My SGMiner config is the following:

Why are you using such a low intensity? 820KH/s is pretty bad for these cards. They should happily run 900 with very minimal tuning.

Temperature. Too hot where I am at the moment to go any higher.

You find intensity increases temps?  I haven't observed that. The number of threads you launch shouldn't affect power consumption (and therefore heat output) unless you are talking about very low intensity. Only clocks and voltages mattered in any of my testing.

Do any of you know how to get the r9 290 to work with linux?  I've been having issues with opencl support, ect.

The same as every other ATI card, but make sure you use thr 13.12 drivers (earlier drivers and 14 beta won't work with the hawaii cards).
