http://www.youtube.com/watch?v=lsiuxim8vsM But seriously, wow, thanks! :o Though I'm partial to Sapphire cards, I guess I really shouldn't complain at all. These things cost 700+ dollars in .au where I am so I still wouldn't dream of buying one for myself. http://www.pccasegear.com/index.php?main_page=index&cPath=193_1309 Title: Re: some donate, some don't, collection for cgminer Post by: jjiimm_64 on January 25, 2012, 03:37:19 AM I already bought the xfx, but if the donations come in quick enough, I did put one of these in my cart. I think newegg takes it out of avail if you have it in your cart. but I dont know for how long.
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102961 edit: I was wrong, my cart was empty the next morning. sorry ck it will be the xfx unless more saphires come in. Title: Re: some donate, some don't, collection for cgminer Post by: sveetsnelda on January 25, 2012, 08:39:45 AM Definitely stick with Sapphire if possible. I know they're all reference boards, but many of the other brands are just becoming "cheap" (not to be confused with "inexpensive"). Sapphire is doing a damn good job right now and actually includes some accessories with the product (the XFX card came with almost nothing). I'm trying to stick to Sapphire and MSI right now for the most part (unless I get a smokin' deal on something else).

Isn't there anyone else that want to be able to use cgminer with the 7970, and see it optimized (sorry ck if I am raising the expectations too much ;) ) we are halfway there... I have the card now. Well, UPS said they delivered it.

Don't you think many of us offered that. Don't you think he deserves at least this much. Can you imagine the number of hours he has put into the program that allows us to have hands free mining....??

Title: Re: some donate, some don't, collection for cgminer 7970 [54.6 confirmed] Post by: -ck on January 27, 2012, 03:27:36 AM True I guess when trying to debug a graphics card, crashes are gonna happen and doing that remotely would suck. Indeed when I was working remotely on that 5970 card I literally had someone who would push the reset button for me 10,000 km away whenever he saw the screen go haywire telling him it had crashed, yet that wasn't entirely reliable either and I'd have to email him regularly... and all I was doing was adjusting fan control on it. We were in different timezones too so he really didn't appreciate me spinning the fans up and down while he was trying to sleep :PTitle: Re: some donate, some don't, collection for cgminer 7970 [54.6 confirmed] Post by: rjk on January 27, 2012, 03:53:23 AM Man, if I had my PDU talking to my KVM properly, there wouldn't be any hassles at all. Give you a login to the KVM and PDU, and them you get remote console access including BIOS and remote reboot capability.
I need to figure out why they won't communicate with each other.

1)ckolivas should be rewarded for his hard work by doing more hard work on the 7900 series ;) 2)I fully intend to tear some 7990s up when they come out, and having cgminer already working on the 7970 cards would be nice.

Love you all so far. Thanks! I'm pretty sure the existing dual card code new in cgminer 2.2+ will be easy to extend to 7990 once it's out. Title: Re: some donate, some don't, collection for cgminer 7970 [approx 50%] Post by: sveetsnelda on January 31, 2012, 05:58:18 AM I see:

ckolivas joined Ozcoin in the early days of both cgminer and Ozcoin, I know first hand the effort he has put in to help ALL of us optimise our miners and earn the maximum number of Bitcoins/day our hardware is capable of. dig deep folks this guy has spent countless hours helping us, this card will enable him to volunteer more hours and help the community more ;) every 0.01Btc helps, for those that can afford more - well that helps more :D Title: Re: some donate, some don't, collection for cgminer 7970 [approx 50%] Post by: xzion on January 31, 2012, 01:13:56 PM 2 from me.

As you may have seen I've done some preliminary work to the git tree since this collection started anyway so that cgminer will run at least satisfactorily on 7970 if not optimally just yet. Thanks to everyone who donated ;D Title: Re: collection for cgminer 7970 [Card as been sent! THANK YOU EVERYONE] Post by: -ck on February 08, 2012, 03:47:56 PM Thanks very much everyone. Arrived, shiny and all :D
Took a lot of fluffing around to get it going thanks to AMD fail. Had to make sure the 7970 was in the first slot and manually edit xorg to make it work. The older driver detected the 6970s only and the newer experimental 79xx driver only detected the 7970. Then I did a little overclocking experimenting and found a nice sweetspot at 1200/1050 (it has a -150 gpu-memdiff limit). See if you can spot the 7970 ;) Code: cgminer version 2.2.3 - Started: [2012-02-09 02:30:05] This is with an unmodified 2.2.3 with its defaults so that's what you can expect from cgminer at this stage at those clock speeds till I can wedge in a faster kernel.

Ck: can you do the comparisons with the clock not set so high. at 1200 they run pretty hot with a high fan, also if you just do down about 50 on the clock, you can reduce the voltage down to 1120 or so.

THANK YOU EVERYONE] Post by: -ck on February 10, 2012, 03:35:07 PM Working on the 7970 tuning, I have tried to port both the diapolo and diablo kernels to cgminer. Alas neither of them are actually working yet, so instead I started modifying the existing poclbm kernel in cgminer to improve throughput. This should work on other GPUs as well as the 7970, but I have no idea if it's better or worse than phatk. When it's released it will get a new date/version number, but I haven't changed the number right now so that people can download it now and give it a try: https://raw.github.com/ckolivas/cgminer/kernels/poclbm120203.cl Remember to delete any .bin files and if you're not on a 7970 with the latest cgminer, you'll have to tell it to use that kernel with -k poclbm. So what's the damage? Well on the 7970 at 1200/1050 clocks, which was getting 694MHash, it's now getting 711Mhash. The 7970 has this unusual behaviour where the hashrate slowly rises for the first 5-10 minutes. Title: Re: collection for cgminer 7970 [Card as been sent!

7970 running at 1200/1050+5% is getting 714 Mhash with -I 11 and cgminer 2.2.5 defaults. Title: Re: collection for cgminer 7970 [Card as been sent! THANK YOU EVERYONE] Post by: -ck on February 13, 2012, 06:17:59 AM The problem, I believe, is that the GCN cards are built to take large vector counts and perform a single instruction on them all at once. This is in contrast to the small vector count of VLIW which can perform large instructions quickly. So, a straight-forward 16-vector miner with simple instructions should work better than a 4-vector miner with multiple instructions. Granted, this is speculation, but from what I've seen of the hardware specs, it should hold true. I tried it, and a 16 vector simplest possible mining kernel had performance which was, unfortunately, appalling. GCN with SDK 2.6 (the only one it works with) really does not want any vectors at all.Title: Re: collection for cgminer 7970 [Card as been sent!

GCN with SDK 2.6 (the only one it works with) really does not want any vectors at all.Title: Re: collection for cgminer 7970 [Card as been sent! THANK YOU EVERYONE] Post by: -ck on February 13, 2012, 10:28:47 AM The problem, I believe, is that the GCN cards are built to take large vector counts and perform a single instruction on them all at once. This is in contrast to the small vector count of VLIW which can perform large instructions quickly. So, a straight-forward 16-vector miner with simple instructions should work better than a 4-vector miner with multiple instructions.

It's getting harder and harder to extract much more :P
1200/1050+5% clocks, intensity 11 - 717 Mhash. Title: Re: collection for cgminer 7970 [Card as been sent!

It's getting harder and harder to extract much more :P I'm going to have to look at what methods you're using. I'm curious as to how the programming differs between VLIW and GCN.1200/1050+5% clocks, intensity 11 - 717 Mhash. Title: Re: collection for cgminer 7970 [Card as been sent!

Title: Re: collection for cgminer 7970 [Card as been sent! THANK YOU EVERYONE] Post by: -ck on February 20, 2012, 05:27:03 AM Cgminer 2.2.7 out. This version fixes the bug with 12.2 ATI drivers. Reworked to use -w 64 by default on Tahiti which is worth just under 1 more MHash. 718.5 MHash now at 1200/1050+5% clocks intensity 11.

I am stuck on windows with untill I can get linuxcoin to cooperate. at 1125/1000 I11 672Mh I am happy with that.. I have not tried to clock it up.. think I will try that now. |
