I can change intensity UP to 24, give me some hashrate power, but this is stable for me.
Memory and GPU is in max. on this voltage, anything above make me crash driver.

[azhago]

If you plan to mine Groestl algo, a 750W power supply is enough for 4 x R9 280X
You can push easily the R9 280X to 7.7/8MHs (1200MHz, 1.2v, still cold)

I don't know the USD prices, but if i convert from EU prices to USD :

4 x R9 280x + 750W corsair Gold + CM (msi z77 g45) + intel g2020 + 4Go =~1600$

~30/32MHs

Prices crashed 2-3 week ago, for example in my country 280x used can buy 181 Eur - cost 275 EUR before crash. Yes prices can fall, but 40 EUR max ? New gpu is not comming in this year

This rate are very nice, what is power consuption for all of this ?

wen Asic dominate Scrypt the price of GPU will Crash !take this in Mind.

This is already happening.I bought a used Radeon 7970 in December for $350 USD off ebay. Just yesterday I sold a New In Box R9 280x for $275.

This is happening for 2 reasons:

1> ASICS are already here
2> Nvidia's Maxwell architecture is better than Radeon in terms of cost vs performance

Nvidia 750ti cards are about $150 new and will run scrypt out of the box at 265KH on 35 watts! A modest over clock pushes it to 280KH and flashing the bios to boost wattage up to 65 will push the card over 300KH. I bought (4) such cards and put a pair into two separate systems. With modest software OC, I am over 6.5MH with Groeslt and a whopping 180MH with Fugue - from each 2 card system.

My buddy built a 4 card system and he is seeing just under 1.2 MH total for script @ 35 watts per card!

Radeon is dead for GPU crypto and doesn't even know it yet. Nvidia has stolen the crown because it is now an energy "sipper".

No = 280x,280x,270s,270s /1100,1100,1050,1050/

Memory i cant underclock under 1000 by sgminer config. Maybe if i flash bios of card, then power consuption will be better.

[brainape]

I run a 4 card 750ti rig.  My hashings are very similar. 

I don't know how to flash the bios so my cards are from the box.  They're pulling ~230 watts.  It was worth the month long wait for these 'little' cards.

I'm fully convinced that Maxwell / CUDAminer / ccminer are on the verge of something huge.

no real crash!!! R9 280x for $175 or less. wen titan (1M/h/4w/40$ my RIG R9 280x is 1M/h/450w/500$ ) and destroy GPU Mining totally

[MinerSVK]

My english is so bad for explain you something about: demand - offer

But i say...

Prices fall 40 EUR down, you say 55 EUR. I think it's not such a difference....


And it does not reflect the time for mining.

[MinerSVK]

That is nice, and powerconsuption for system or per card, or two cards

[child_harold]

Someone on the french forum about mining i come from run some tests with a simple rig setup, with 2 x R9 280X

All tests ran with the same frequency etc..
Each algo can be optimized, but for comparison, it's good.

Power at the wall:

Idle
80-90w
 
scrypt
550W - 2 x 720khs
 
Scrypt-N
537W - 2 x 350khs
 
Scrypt-jane  
485W- 2 x 133khs
 
Groestl
271W - 2 x 7 025khs
 
Myr-G
295W - 2 x 9 920khs
 
skein
440 W - 2 x 212 500khs
 
Keccak
430W - 2 x 316 000khs
 
X11
285W - 2 x 2 080khs

Result : Groestl is the most gpu friendly algo, for power, temp and noise, even better than X11


a little tuning on one of mine:
4 R9 280x + 1 x 7950.
3 R9 are overclocked at 1250MHz, the 4th at 1150MHz - 1.2v
The 7950 runs at 1100MHz - 1.15v
Memory for all 4 run at 1000MHz
Look at the temp (scrypt : between 75 to 83°C)

Result : Groestl is the most gpu friendly algo, for power, temp and noise, even better than X11

Just a reminder

[stizz]

That is nice, and powerconsuption for system or per card, or two cards

35w per card is what i have read.

I have not done much comparison testing, but my one rig with (2) 750ti in it is pulling 195w when I mine Fugue and it only pulls 175w when I mine Groestl.

System is win7 32 bit running on an i5 2500k chip.

My other 2 card system has a Q6600 chip, so it probably sucks a bit more wattage.

[brainape]

I'm curious if I could run to instances of ccminer using my 4 - 750ti.

1 instance calling 2 cards to run GRS and 1 instance calling 2 cards to run on FC.

I honestly have no idea if this is possible.

no promises but it might just work by default. The other night I accidentally (quadrupal?) clicked my Groestl_start.bat and went to bed. The bat launched twice.  so when I went to look in the morning, I had two ccminer cmd windows open, and each one was reporting back half my expected hash rate. It did take a reboot to get one single instance running back at full hash however.

Maybe Chris B can weigh in. There must be a way to indicate which GPU threads you want to use.
