Title: Re: 7 sapphire 5830 xtreme Post by: superfastkyle on April 13, 2012, 10:30:08 PM I'd be willing to pay $630 for all if you interested
Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 13, 2012, 10:31:08 PM no thanks
Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 14, 2012, 07:17:32 PM I just got 4 more of these. Since i have so many i decided to put together another computer. They run 1050/300, temps 60, fans 35%, hash 285, no extra volts.
Title: Re: 7 sapphire 5830 xtreme Post by: zvs on April 15, 2012, 11:21:02 AM I just got 4 more of these. Since i have so many i decided to put together another computer. They run 1050/300, temps 60, fans 35%, hash 285, no extra volts. this makes no sense #1, i had 7 of these and none were stable at 1050/300. the highest was 1030/300 #2, the temp would not be 60oC with the fan at 35% unless you had an ambient temperature of 15oC and/or some big ass industrial fan blowing right into the case #3, i get 325mhash at 1000/300 Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 15, 2012, 06:06:30 PM Every chip is different. Out of the 4 that im using every one does 1050. Im even thinking about trying for more cause they do 1050 with no problem. With some extra volts they might clock higher.
Where i live has been 40-50F the last few days. Im also mining caseless with risers and plenty of space between each card. I wish i was getting 325 hash but i am getting 285. Title: Re: 7 sapphire 5830 xtreme Post by: superfastkyle on April 15, 2012, 08:05:21 PM 1025gpu/300memory/1.163v is what i start at, will do 325megahash on BAMT, out of 7 extreme 5830 have only seen one that would only be stable at 1015 most will do 1040, its got to be a driver or bad miner flags to be that low
if your using windows I use guiminer and phoenix with phatk2 with similar results -k phatk2 VECTORS BFI_INT FASTLOOP=false AGGRESSION=13 WORKSIZE=256 Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 15, 2012, 08:08:15 PM OK so i have been using poclbm since i started mining and i have never tried another miner. I just tried CGminer and noticed some big changes in my hash. I run them at 1000/300 and was getting around 275K. With cgminer im getting 300K. I like cgminer so far im gonna try for 1060.
Title: Re: 7 sapphire 5830 xtreme Post by: superfastkyle on April 15, 2012, 08:12:24 PM also what amd driver are you on? I usually stick with 11.10, version 12 doesnt seem to work very well for me
Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 15, 2012, 08:13:54 PM I always use the latest. I have tried a few older versions and never noticed any improvement.
Title: Re: 7 sapphire 5830 xtreme Post by: superfastkyle on April 15, 2012, 08:17:01 PM because you were using poclbm probably, it definitely makes a difference with phoenix
Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 15, 2012, 08:19:12 PM OK i will try 11.10 and report back.
Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 15, 2012, 11:26:07 PM I didnt see any gains with 11.1 vs 12.3. Two of my cards run at 1060 with no volts. Hash is 325K. Temps around 65 and fans 55%.
Title: Re: 7 sapphire 5830 xtreme Post by: superfastkyle on April 16, 2012, 02:30:02 AM yeah its really hard to totally revert the drivers maybe someone else has figured out the trick, I've just started from scratch when I found out 12 didn't work as well. I think it has something to do with the sdk version they install but I'm not sure
Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 16, 2012, 03:54:53 AM Any ideas why windows wont detect a 5th gpu? I tried 12.3 11.12 and 11.1 with no luck.
Title: Re: 7 sapphire 5830 xtreme Post by: Xmufa23X on April 16, 2012, 05:00:34 AM Are these new, refurbed, used? 25 BTC is a little high for the 5830 market right now. You can buy a used one for $100-110 (~21 BTC) on Ebay. I grabbed one for $92 with free shipping. I'd consider buying one off you for 20 BTC. But I don't really know how buying/selling works on the forum. Or how to avoid scamming. Do you have any references? Assuming all goes well, I'd consider buying a 2nd off you.
Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 16, 2012, 05:06:53 AM Refurbs from newegg. They are under warranty. I have the receipt. $120 is my price. To avoid getting burned use escrow or buy from people with rep. I have references for good sales.
Title: Re: 7 sapphire 5830 xtreme Post by: zvs on April 17, 2012, 06:57:49 PM I didnt see any gains with 11.1 vs 12.3. Two of my cards run at 1060 with no volts. Hash is 325K. Temps around 65 and fans 55%. oh, that makes more sensei guess whatever you were using before probably wasnt aggressive enough... maybe using 85% of GPU or something, that would keep the temps down some Quote -k phatk2 VECTORS BFI_INT FASTLOOP=false AGGRESSION=13 WORKSIZE=256 i've noticed when i put the cards above aggression 9, it starts using a good amt of CPU cycles for just minimal gains in hash rate... if I have three 5870's at agg 12, it actually lowers their performance (100% CPU usage).. if I have three 5870's at agg 9, the cpu usage is like 1 or 2%... agg 10 would be about 20%. though i've never tested the actual power draw and whether it's more efficient or not anyway, i've been using some old dual core CPUs I had, w/ one core disabled and the other one underclocked and undervolted.. maybe if you have a better CPU, it wouldnt be so bad. Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 17, 2012, 07:01:16 PM Ya thanks for the heads up. Now that im using cgminer i see why you were questioning my numbers.
Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on April 17, 2012, 07:05:01 PM I see some people reporting 330-350K with these 5850. Im jealous.

Sorry for bumping topic, but want something to be jealous of? Try over 510 mhash on a single 5xxx GPU. http://dl.dropbox.com/u/9768004/fast5870_2.png Title: Re: 7 sapphire 5830 xtreme Post by: xurious on April 27, 2012, 10:26:17 AM Those cards won't last long at that frequency. After a few months I've had them die at speeds above 950.

With the Sapphires by chance? I might want to lower my clock rates on my Sapphires then...Title: Re: 7 sapphire 5830 xtreme Post by: xurious on April 27, 2012, 12:22:47 PM I see some people reporting 330-350K with these 5850. Im jealous. That should be easy. I'm at 295mh/s with my 5830's. Title: Re: 7 sapphire 5830 xtreme Post by: xurious on April 28, 2012, 02:10:29 AM Those cards won't last long at that frequency.

I might want to lower my clock rates on my Sapphires then...Killed 1 xfx 6870 at around 950 and a sapphire 5830 xtreme at the same speed. I still have the dead sapphire, haven't found the time time RMA it :/ Title: Re: 7 sapphire 5830 xtreme Post by: fabrizziop on May 01, 2012, 02:25:09 PM I'm interested, do you have rep anywhere?.

Title: Re: 7 sapphire 5830 xtreme Post by: BTC guy on May 18, 2012, 09:05:57 PM Yes, all of my 5830's do 325 hash. Other people are reporting more.
