Sapphire R9 290X Tri-X OC Hashrate?

[suwaro626]

Hey guys, can anybody who has a R9 290X Tri-X post their hashrate? I'm in the market for new hardware and I'm trying to see whether I should buy 290Xs or 290s. Thanks.

You need to learn how to tune...

I have 4x Sapphire R9 290 (NON-X) Tri-X OC cards running at 945KH/s and 900KH/s (for a card that won't take the memory OC).

Rig Specs:
Gigabyte Z87X-UD3H
4GB DDR3 RAM (cheap stuff)
Cheapest LGA1155 CPU Available
4x Sapphire R9 290 Tri-X OC

SGMiner Config:

Code:

"gpu-threads" : "1",
"xintensity" : "1100",
"thread-concurrency" : "25601",
"worksize" : "512",
"lookup-gap" : "2",

"gpu-powertune" : "20",
"gpu-memclock" : "1499,1499,1499,1250",
"gpu-engine" : "1040,1040,1040,1020"

"gpu-fan" : "80"

Key points: if your card won't overclock to 1499,1500, then downclock it to 1250 to see some performance gain.

Every tri-x OC card should be able to do 900KH/s+ straight out of the box, with no burn in.

My Gigabyte R9 290X is getting 863Kh/s with WU:780/m and 79C

setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt -o stratum+tcp://scrypt.megamultipool.com:80 -u user.user -p password --intensity 20 -g 1 -w 256 --lookup-gap 2 --thread-concurrency 24550 --gpu-engine 920 --auto-fan --gpu-memclock 1500 --gpu-powertune 20 --temp-target 80 --temp-cutoff 95 --temp-overheat 92

Why do you have GPU engine so low?  And stop using intensity - switch to xintensity and you will see several percent hashrate increase.

[granitepeaker]

I've tried about a dozen other higher GPU engine values higher and they all resulted in a lower hash by about 100-150Kh/s lower.
What GPU engine value do you recommend I try? I've never heard of xintensity, I will definitely look into it.  As a side note. I've never noticed any difference at all in performance with the following included:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
Am I doing something wrong with the above code?

You only need to run the setx command _once_ on a windows machine, and the variable will be fixed forever.  If you don't do GPU_MAX_ALLOC_PERCENT, cgminer simply won't work with higher threadconcurrencies.

GPU engine depends massively on BIOS.  Some 290 (and X) BIOSes will drop in performance past 1000, others drop past 1020, and still others keep climbing all the way up to and beyond 1080.  Typically 1000 seems to work on everything tho, if it doesn't, try another BIOS (e.g. a different manufacture like Sapphire).

My favorite BIOSes on the 290 at the moment are:
Powercolor AXR9 290 4GBD5-MDH/O  015.042.000.000.000000  (does 930KH/s at 1499/1040 mem/engine)
Sapphire R9 290 4096 MB 015.041.000.000.000000 (does 899KH/s at 1499/1000 mem/engine - DO NOT USE THE 015.041.000.001.003747 BIOS, you will lose 20-30KH/s at the same clocks)
and
Sapphire R9 290 4096 MB Tri-X OC 015.042.000.000.000000 (does 961KH/s at 1499/1080 and 954KH/s at 1499/1070 mem/engine)

You will have to experiment a bit to find the best BIOS for your 290X.

I've now got it set up with a .conf file and running kalroth's 3.7.2 cgminer and can't get as high of a hash as I was getting before without the xintensity.  I think my card has 2816 shaders so the xintensity would be 372?

Try bumping it up a good chunk, say double.  Personally I didn't have much luck with kalroth's miner, even though it has the same xintensity code as sgminer.  372 makes sense by my math.  I use 1100 on my 290 (non-X).

Also set your tc to a multiple of 2816, and then add or subtract 1 to see which gives more efficiency (usually adding 1 will give you a bump).  Say, 28161 or something.  xintensity means you don't have to push TC so high to get the same performance, because you are aligning the number of threads launched with the number of threads you can actually run at one time.

It's better to check Watt rate and temperature also.

A have 2 of 290(not X) Tri-X and get:

863 KH/s each with 632 Watt and temperature 77`C (965KHz Core, 1250 Ram)
905 KH/s each with 677 Watt and temperature 88`C (1000KHz Core, 1500 Ram)

It's 4.8% rate gain and 7.1% Watt gain. Also I don't like 88`C and possible card crash.

So it mine already 6 days 24/7 without problems. I use sgminer 4.0.0  xI:400

PS: I use TC: 20481 don't know where I found it, but it give me better rate, than higher values
PS: xI don't make much difference. I get almost same rate from 200 to 600

Why?  Power consumption is almost totally irrelevant at current scrypt profitability.  You could use double the power for 10% more hashrate and probably come out ahead right now.

This said, my 945KH/s+ cards run at a cool 65 degrees C max (lowest is 57 degrees).

PS: I use TC: 20481 don't know where I found it, but it give me better rate, than higher values

Would be shaders * 8 + 1, which makes sense.  I find shaders * 10 + 1 to be solid on these cards, but this also won't make a huge difference.

PS: xI don't make much difference. I get almost same rate from 200 to 600

If by "almost the same rate" you mean several percent, sure.  But yes, the key is really that using xI over I makes a decent difference.

Looks like you don't use standard Sapphire Tri-X card. It's quite hot. 74'C is minimum for me

Of course I use standard Sapphire Tri-X cards...  Sapphire R9 290 Tri-X OC, no mods.  I just have plenty of experience running rigs.  

I have banks of reference Sapphire R9 290s running at <60 degrees too:


Stock unmodified reference cards.  899KH/s stable as a rock too.

[szwagier]

whats your vcore's for these cards?
got 5 pieces.

one is going dead on stock (gpu0) trying on lower gpu speed (now 900 , stock 1000 ) at 1000 is going dead after few seconds - probably I dl RMA.
Mem clock lowered 1300->1250


cooling is same for all - but temps are weird high.
Seems like they had been assembled in rush!

Stock.  I never use windows, so can't touch the voltages on Hawaii chips yet.

Not exactly uncommon - you could RMA it, but is it worth a 10% hashrate boost to lose time waiting for a replacement?  Have you tried 947 engine?

You can re-thermal paste the cards if you don't mind losing your warranty, and it might help even things out while shedding a few degrees.  I have also observed some cards that read at higher temperatures but don't actually seem to be (e.g. the measurement seems skewed).  As long as they are within range, I wouldn't be too concerned.

I do agree they seem like they were assembled in a bit of a rush.  But not as bad as the new MSI 290 cards... those are bloody weird, but good hashers anyway.

You set 100% fan. And ambient temperature 10`C?
I have tried 100% fan its quite loud and got 69`C. Ambient temperature 21`C.
Set back to 55% fan (2740 RPM). It's 74`C back but quite acceptable.

but notice 15% invalid shares.

I found these card are undervolted - when high stressed it just cant make it - but in games - ok , yet...

orginal vddc - 1.020 (stress) at 1.070 (stress) should be fine still testing

I have to check every single one

What settings are you using?
Sgminer, karloth or cgminer 3.7.2?

I never got more than 970 from my Sapphire R2 290X
