Cannot get 5830 above ~225 mhash/sec

[mike678]

And everything seems to be running smoothly. If i try to go over 880 it doesnt like to do much else...and this is my main computer, not a rig.

Yea if you need to use this rig don't expect over 300 megahash.

Maybe wildboy should try drivers 11.8 with newest GUIminer / openCL with -v -w128 -f25 with w/e oc he can get out of it.

With my xfx 5830, I am receiving 319 Mhash/s, then when using the pc it drops to 310-314 Mhash/s, second card just sits at 323mhash/s, as it just mines.

You have a link for the 11.8 drivers? I might try that on the weekend when i have more time...

You could also get them from Guru3d, but posting link to them violates TOS, "i think".

what psu are you using then you might not have enuff wattage

Actually, now that i think of it, that may be the case, as i only have a 475 watt psu - and i have 2 HD's, DVD-RW, Quad-core, fans, etc...
BTW, i got some pictures after i installed the video card (but before second PCIE power cable):

it's been a long time since i've seen a psu with a in and an out on it...

I bought it around a year ago, oh and its 480 watt if that makes any difference:

well my old psu was 450 and i ran 2hdd  2 cards and duocore but couldnt do anything else maybe it time to upgrade psu and get another card haha. this is what replaced mine with its cheap works great for me http://www.newegg.com/Product/Product.aspx?Item=N82E16817182191 it runs 2x 5830s and 1x 5770.
 idk but i think 475watts should be fine for 1 card. 1oo watts for system and 150watts for card seem fine

Yeah, i like Rosewill too - but this one is cheaper and still has good reviews:

But i noticed yours has 6 SATA, while mine has 4, which i need when as i add more HD's (i have another 1TB coming on Wednesday).

I can't find that exact psu anywhere however the currently avilable logisys psu's are only rated for 16a(192w) on the 12v line i can't imagine that one is too different if you have a quad core with a moderate ammount of load on it as well as a 5830 mining they're going to fight over that 12 volt rail, tons of amperage on the 3.3 and 5v rails though  28a(92.4w) on the 3.3v and 36a(180w) on the 5v. they're not lieing about it being a 480w psu it's just designed for older systems where things were more dependent on the 3.3v and 5v rails. unless there's one i can't see that system only has a single pcie slot you'd be fine with a psu like this one http://www.newegg.com/Product/Product.aspx?Item=N82E16817182044
two seperate 12v rails with 15a and 16a respectivly neither the cpu or the gpu will be power hungry

dump that junk PSU. as you clock up the 5830 its power draw goes up, and the PSU cant meet it 12v draw. 12v drops. hence, crash. and that psu is probably over rated  by 20-30% anyway, most all generics are.

silverstone, antec, corsair, seasonic, pc power and cooling. any 450+ watt psu by those will be fine, and will actually deliver whats it rated for at real world temps. but get a reputable brand like one on that list. most rosewill and cooler master are not (although a couple got good ratings at johnny guru I think, unsure on that). some use em and it works, for a while at least, but personally I dont trust em.

grab a 650+ if you plan a 2nd card at some point, otherwise 450 or so is good.

once you have a decent PSU you should easily hit 1000+ Mhz on the core.

LOL - my PSU fried the other day, so now i cant mine at all until Tuesday when my other PSU (i bought a cheap 680 watt for now) gets here. Ill see what kind of performance i get out of that.

I recently switched to cgminer 1.6.0 as I noticed an increase in Mh/s and stability. The following command line gets me 430Mh/s from my 5850 and 230Mh/s from 6770:

cgminer -o http://host:port -u x -p x -I 7 --submit-stale

My 5850 is set to 1050/375 @ 1.2V w/ 75% fan.
My 6770's are at 985/300 @1.124v w/ 100% fan.

ATI's CCC is capped at 900 MHz overclock so that card is seriously defective if it can't even make it that high

my sapphire 5830 can make it to 965 with trixx without crashing

try the flags -v -w128 and -f2

dont use ccc. use trixx or afterburner

[wildboy211]

Changed my 5830 (from a Diamond brand to a Sapphire) and i can overclock much higher and getting higher Mhashes (i can overclock to around 950/300 which gives me around 315 mhash.

[Valalvax]

I've got my 5830 (not sure what brand sorry, no markings on it at all, bought from eBay) running at 960/300 doing 295-310MH/s

Sorry, using CGminer 1.6.1

Thats about what mine is running stable (can get more, but i wont be able to do anything else).

If I take it much higher it starts to crash leading to lost time


I've only got a 550 watt psu

Yeah, i had to upgrade my 480 watt to a 675.
