I see a lot of questions on best clocks, options, miner program, and the like to use for any particular card. The hardware comparision page on the wiki used to be a viable resource, but I think it can be rather intimidating and is not uniformly formatted. I think it would answer a lot of questions before they are asked if we had a thread listing the best (aka highest MHash) settings for common mining cards.

I will maintain the first (and second if need be) post of this thread as a hopefully organized and easy to read list. Please post only if you have beaten the previous MH/s record for that card.

EDIT: In order to better provide the information this thread is designed to provide, I am now adding an overclocking limitation. Core clock can be no more than 100 MHz or 20%, whichever is lower above the stock core clock for the reference model (aka AMD stock reference). This is being implemented to more effectively convey effective software settings. Comments or suggestions are always welcome.

Do note that this is not a overclocking bragging thread. This is a thread designed to server the majority of miners, and certain criteria apply:

• Air Cooling or (Sane) Water Cooling Only
• No Hardware Modifications
• Must Run Stable for at least 24 Hours
• Invalid Shares under 2% for 24 Hours
• Stock Voltage

If you got a 5870 to 600 MH/s for two minutes by taking it apart, resoldering and rebuilding it, and running it in a pool of liquid nitrogen, that's wonderful, but that's not what this thread is for. I can't cover everything; use your judgement as to what is or is not appropriate. Remember, this thread is to serve the majority of miners. Please keep it as such.

Well, I was under the impression that the vast majority of miners used air-cooled cards. If that's not the case, please correct me.  ;D

I suppose I can start a "Insanely Overclocked MH/s Bragging Thread" if you want. I just intended this one to answer a lot of newbie questions before they were asked.

I can't agree with that.  I'm more comfortable running my cards cooler and with less voltage.  Less Power = more profit

Edit:  It would be nice if you made a separate table for alternate configurations.

I'm not disagreeing with you on the preference to run cards cooler, just re-stating my instructions.

If you think I should do that, I suppose I can, but my worry is that this will just turn into the Hardware Configuration page on the wiki, which is the problem I was trying to fix.

Anyone else have thoughts on this?

What should be done here is specify a typically obtainable GPU core overclock that everybody can use for a particular card, then compare who can get the maximum Mhash/s out of that card at that overclock. This will help users discover maximum performance through comparing software setup, rather than becoming that overclock bragging contest. OS/bitness/motherboard/CPU are all largely inconsequential, and only need to be recorded for posterity.

The most important things to accurately note:

• GPU model (+memory size & make, manufacturer part #)
• Driver software version, OpenCL/SDK if not the one included with driver
• Memory clock MHz
• Miner software & version
• miner kernel & version
• miner kernel parameters (worksize, vector size, other settings)

Here's mine to toast the above speeds, (I am currently cranking 350 mhash/s out of this 5830 at an overclock most won't obtain)

I agree, that would be ideal. Unfortunately, I doubt there is any consensus on what a "typically obtainable" core overclock is, and I do not personally know enough to determine one, so I decided to leave it to the judgement of the submitter. If there is a resource I could use to obtain "reasonable overclocks", though, please share it; I would be glad to change the guidelines as such.

Looks like the 5830 info only got half-updated in the original post.

The only reason I suggest some overclock, is that this affects ideal memory speed; ideal memory clock will follow core GPU clock in a non-linear way. ATI cards can typically go from stock 800MHz to 950+MHz given cooling and voltage. The fans are programmed to be quiet to mask their huge power draw, and this let the chips go over 90C. You might look at https://en.bitcoin.it/wiki/Mining_hardware_comparison, ignore the stock speed posts, and take the smallest or second-smallest overclock that a card has rounded to a nice number.

Fixed, thanks for pointing that out.

Instead of limiting overclock, what if I limit temperature and fan speed? After all, overclocking itself doesn't kill your card; overvolting and/or running at high temperatures does. (And running at high fan will kill the fan quickly) "Stock speed" varies card-to-card, and looking at the wiki page, the average overclock is extremely variant. How does 70C and 60% fan speed (in addition to the already-implemented stock voltage) sound for limitations?

That will only show variations in the product itself and make for completely non-replicable results. Two cards out of the box with serial number right next to each other might run 5C different due to manufacturing and assembly differences. One user might have an open frame rig, one might put it in his Dell with only one system fan. Those two cards, though, will get identical mhash results if run with the same software settings at the same clocks.

Fair point, strike that. I suppose I'll look over the wiki and see what I come up with.

Thanks for making this thread BinaryMage. This is exactly what I was looking for, https://bitcointalk.org/index.php?topic=62071.msg743905#msg743905 , results that could be trusted to teach n00b5 like me some OC 5k1llz. :D
I don't trust that wiki, if there are too few results it's impossible for new people, like when I first started reading, to determine credible results. Instead of teaching skills they could be teaching kills, which is not so good. At least someone with a little more knowledge has taken on the task for safe guiding ideas.

Not relevant.

Each GPU performs differently.

One may do 1000 without voltage increase and another ( of same model ) might only do 800 on stock volts ...

YMMV

Not relevant.

This thread is for finding the fastest software miner settings.

One may overclock more than another, but the competition is to find the fastest hashing miner at a particular overclock.

Absolutely. That's why I chose the term "skill". It will require effort, gong, over time, fu, to see what you can achieve. :D

Sorry I haven't updated this thread in a while, I was taking a few days break to clear my head. I'll update it momentarily.

Sounds like two different threads are needed. One for software settings, and one for a general overclocking guide. I'm no overclocking expert, but I probably could write a guide like that if no one else steps up. Thoughts?

Alright. Main post has been updated, with new regulations limiting core clock to 100 MHz or 20%, whichever is lower, above reference stock. That seemed a fair way to limit clocks that could be applied to any card, wouldn't allow insane overclocks, and requires no judgement on my part. As always, suggestions, corrections, etc. are always welcome.

The smaller of +100Mhz or +20% is +100Mhz in all cases, you would need core clock under 500MHz for the 20% rule to take effect. "Running stable for 24 hrs" etc doesn't matter because these are easy overclocks, you just want to run the miner until it has results at least xxx.xMhash/s stable accuracy.

Note that running a lower GPU core overclock for benchmarking will also affect the "sweet spot" for memory underclock on 2.1-2.5 SDKs. My own research shows that changing a 5770 from 1000->850MHz will change the best memory speed from 295MHz to 270Mhz. This is important to note both for this competition, and for trying these results on your own miner when you want to go back to maximum overclock.

Here are the official AMD stock core clocks of common mining GPUs, and their "competition" overclock of +100Mhz (which is significantly lower than typically attainable, but should be achievable by all [except perhaps 7970 @ 1025MHz]):

Model	Shaders	Stock MHz	Overclock
5770	800	850	950
5830	1120	800	900
5850	1440	725	825
5870	1600	850	950
5970	3200	725	825
Model	Shaders	Stock	Overclock
6850	960	775	875
6870	1120	900	1000
6950	1408	800	900
6970	1536	880	980
6990	3072	830	930
Model	Shaders	Stock	Overclock
7950	1792	800	900
7970	2048	925	1025

(Note the table above highlights the numbering sham that is the 6xxx series; a 5830 gets about the same hashrate as a 6870 when pushed to the similar max overclock, as they have the same number of vertex shader cores.)

Just wanted to say the 5970 at 775mhz core 300 mhz memory and 1.02v works well, thanks for the suggestion, sapphire 5850 runs at these clocks fine as well. This definitely looks like this may be my summer clocks. Am pulling 911 watts right now with two 5970 and two 5850. 2102mhash using bamt

That can't be your GPU voltage, or it would be a smoky pile of smoke. Plus, see edited original post and above for new GPU MHz to benchmark at, so we can measure who's the best at tweaking their mining software.

You are correct, theres a typo in there the correct core voltage is 1.17
I also should propably mention that the stock fans have been replaced with Arctic coolings Accelero Extreme.

100 MHz was the intent, yes. I simply included the 20% to ward off the inevitable obscure low-clocked (perhaps laptop) GPU for which 100 MHz is not an easily obtainable overclock. Running 24hrs stable is in there for the same reason, even though I agree it is somewhat redundant.

Isokivi, that is an excellent overclock, but it does not meet the guidelines. (Core clock too high) I do apologize if my example misled you; it was created before the edit and has now been updated.

Glad I could help :)

As I read these 500+ Mhash with 1090Mhz numbers I gotta say "man I was stupid to buy that xfx card back in the day. Even more so when I knew I'd try to oc the hell out of it eventually". I got 955mhz core, 300mhz ram with bamt 0.5 @ 438Mhash/s. btw the power draw delta from idle is 143w(wall). My PSU is under this load around 90-91% efficient.

I have 13 diamond 5970's from newegg

Perhaps a mean with a variance would be more helpful here.

Temps? (If you want to make it easy, you can use the template in the OP)


Updated. Those are some impressive numbers.


A mean of what data set? The wiki?

Whatever you decide is a useful and valid data source. I would take just the submissions in this thread. That way you can ask questions to the submitters about the some settings that you cannot do via Wiki.

Hmm. I'm not sure I have enough data here for anything meaningful. If I see a result off from the norm, though, I'll definitely query more closely.

Updated. Kept the other 6950 due to it having locked shaders.

That would be expected! I should have posted with the same clocks to compare locked/unlocked more accurately. With the multitude of 6950 models, this list needs a 1GB version too.

There was one posted by bitlane on the first page, but it had the same MH/s as his non-1GB model, so I didn't think it worth adding. Memory size is effectively irrelevant to hashing power, so unless it affects necessary settings, I don't think it would be necessary to differentiate, but I've never had personal experience, so enlighten me if there are any significant differences with regard to mining.

What did you undervolt it to?

From 1.088 to 1.037 Mining and Gaming runs smooth.

For now 1.024V 850Mhz Core runs all good.
5850 MSI two cards, each arround 330Mh/s

Sapphire radeon 7970 on air, cgminer 2.4.1, default cgminer settings (which work out to -v 1 -w 64 -k poclbm) 8):

73.0 C  F: 52% (2929 RPM)  E: 1230 MHz  M: 1080 Mhz  V: 1.170V  A: 99% P: 5%

Ambient temp ~17 C. AMD driver 8.921 AMD OpenCL SDK 2.6 on debian linux stable 64 bit.

(note fan speed looks slightly different because GPU status line taken a few seconds later).

Huh, something doesnt quite add up, a 5850 at 850 doing 400Mh , either you run imaginary superman juice on that card or something doesnt add up, seems way to high for that clockspeed.

Your right, that was only a peak. ^^
Under Desktop usage the cards have ~330Mh/s

That's very strange - running non graphically-demanding programs should not take 70 MH/s off...

One Day i open the Monitor and the last thing i see for a few second was 800Mh/s on the Guiminer. Then it fall back to ~660.

You should find these results interesting I think.

The key is running a second worker.

Those are fake reports of guiminer I guess. Best to check your real hashrate is to use 24h stats on ozcoin. And could be as well that you're getting extra mhashes out of your cpu. Check your cpu usage.

Been there, done that. The results are legit. I've been using those settings for over 6 months and both guiminer and every pool I've mined at show the same results. I can't really check results over a 24 hour period as I'm not a dedicated miner, I'm a dedicated gamer.

Run a second worker on phoenix 1, and you get a major boost in Mh/s. Well, you do with 6870's anyway and someone else told me that they got a 40 Mh/s increase on a 5830 at stock settings.

Just for verification, would you mind posting a screenshot? Not that I don't trust you, but those results are beyond anything I've ever seen for a 6870.

6870 Northern Islands has 1120 stream processors of the same architecture as the 5870 which has 1600. Performance is linearly related to architecture * stream processors * Mhz. Therefore at exact same clocks, the 6870 should be (1120/1600) 0.7 * Mhash of a 5870. At 1000Mhz, the 5870 gets at best ~460Mhash. Therefore a number as high as 375 for a 6870 is ... highly unlikely.

Here's some I posted in another thread the other day:

https://i.imgur.com/jr5jy.png

https://i.imgur.com/x6T1I.png

And here's another one I just took:

https://i.imgur.com/rZVOK.png

What makes you think that a 5870 can only get ~460 MH/s? Have you tried running 2 workers on a single 5870? Maybe you'll get over 500 MH/s if you do.

I'm sorry, clearly I don't know what I'm talking about.

I'm not saying you don't know what you're talking about, I'm asking if you've tried running 2 workers on a single 5870 using Phoenix and phatk2.

Interesting so when my Icarus ran for 3.5 hours at a share submission rate of 5.60 shares a minute I can take that as proof that an Icarus can hash at 401MH/s ?

No my Icarus (with default bitstream) can hash at a MAX of ~380MH/s

At 5.4 shares/minute 400 shares is only 74minutes ....

You seriously need to run for 24hours or your figures are quite MEANINGLESS.
Even at 24h it's possible to get a variance high enough to make it look better than it is.

I can't, I've got too many games to play and not enough time to play them. Sure, variance can make it look higher (or worse) but by around 50 MH/s on a consistent basis ever since Catayst 11.7 came out? I find that highly unlikely.

Shares/minute (submitted - not calculated)

I not sure what trying to say. If you're asking for my shares/minute, then the answer is in the screenshots.

77 / 15 = 5.1333...
81 / 15 = 5.4

Yep as even that those 2 inconclusive short rounds show.

You keep stating that the MH/s was blah regularly - which of course you'd expect it to always be consistent.
However to determine if it might be accurate is to ether look at a long term shares/minute or look at the shares/minute you get regularly over time.

As that one shows there, it varies by 5% easily (but it can vary a lot more over short a period of time)

Like I said, I've been running with these settings since Catalyst 11.7 came out. It was that update which gave the increase. I already had 2 workers mining seperate pools at a total hashrate of ~315 MH/s and after that update my hashrate shot up. I've already determined that it's accurate, I don't need to do so again. That is my hashrate and it is due to the second worker.

If you don't want to believe that, then that's your choice. If anyone wants a possible extra 50 MH/s though, all they have to do is test this themselves. You don't have to take my word for it.

I don't care what the hash rate says.
I'm not gonna take your word for it coz all you are doing is quoting what some program is telling you.

I care what the shares/minute say over time.
That can't lie. It has variance. As you just shown yourself with those 2 numbers.
But over a long period of time it will tell you what your hash rate really is.

i try it and notice 10mh/s more for two 5850 850mhz. I can rise the gpu speed, but first i want to test this improvement for 24h.

Updated, thanks guys.

Mabsark, just so you know. You should really take another look at the post several people have made on the previous page and take their words for it. They have stated your conclusions are incorrect. They have also told you why they are incorrect. In addition to that you have told us in your own words how your reported numbers are completely incorrect and this is why the assumptions you have made with this data and believe to be true are in fact false.

With that said, if you are at all interested in knowing the true speed and potential earnings your hardware are capable of. You should really attempt to absorb the  comments and help those people have offered. If you go to either of the post made by ckolivas, and follow the link in his sig it will take you to the most widely used mining software miners are mining with. You may find it a little intimidating and a bit more in depth than guiminer, but it will not mislead you with false stats and will give you a more realistic view of wats really goin on when you are not playing games.

good luck and may the force be with you

Why u guys put the card HD 5850 at 560 Memory clock isnt  300 better or no?


i was using 840   and 300 memory clock.

~334 mH/S do i have to change something?

Host OS: Win7 - 64bit extreme
Driver Version: catalyst suite (minimal installation) 11.11
Mining Program: cgminer 2.6.5
Command Line Flags/GUIminer Settings: -k diablo, worksize: 256, vectors: 1, intensity: 9, gpu-threads: 2
Other Information: 4 cards, seperated by 1x-16x pcie riser, without plastic on the fans. sempron 140 (unlocked to athlon II X2 4400e) and some 900watt psu. GPU vddc 1.065 V

Anyone could tell me why my cards only run around 279? I tried bamt with phoenix, it gave me about 300mh/s on same settings. Phoenix on win7 will give me like 850-900 only (maybe because i cant overclock properly). Any other kernel performs worse (using diablo).

Please anyone?

Experiment with different driver versions?  I thought catalyst 10.6 were meant to be best for 5xxx cards.  Also you're not having problems with the 100% cpu bug are you?

I just saw i have the 100% cpu bug. i tried 11.11, 11.12 (no difference for me) and 12.6 (worst)... ill try 10.6, i thought 11.11 was the best.. thanks in advice!

edit: thats odd. i now have sdk 2.5 running (drivers 11.11, it seems the driver version doesnt effect mhash, but sdk does). I have 1mh/s less than before. Wtf?

edit: fixed the 100% cpu bug, using 12.6 drivers but 2.5 sdk. Still no improvement except 100% cpu bug is gone. Any point in using older sdk than 2.5? Is 2.5 the best choice for cgminer 2.6.5 with diablo kernel?

I dont see whats the best combination. is it the kernel? Phatk performs way worse than diablo.

edit2: for some reason sdk 2.1 didnt work with cgminer

on a 5830:
Phatk2 - with BFI INT enabled, 256 worksize, vectors (2vector), at ~360MHz RAM and as high coreclock as you can get. Look at my previous posts on the first page of this topic.

SDK 2.5 is a good choice, you have to make sure that if you have ever installed a driver after 11.11 or SDK 2.6+ that you manually go in and remove the opencl files left behind by SDK 2.6, neither the uninstaller or a reinstallation of an older driver properly removes them. Stream SDK 2.1 will get +1%, but for the time it will take for you to get it working (substituting around files, newer miners won't work right because this SDK only support OpenCL 1.0, etc) it's not worth it.

i see, thanks. I just dont know how to install/use phatk2. Where do i get the phatk2 kernel from? I found this site containing phatk2:
https://github.com/DDarko/Phoenix-Miner/tree/master/kernels/phatk2

but where to put it? Please, your help is appreciated very much

edit:

i tried to replace the original phatk120823.cl or so with the kernelfile i found (phatk2). Get an error:


same error when i call the kernel phatk2120823.cl and use -k phatk2

As you mentioned its hard to deinstall higher drivers/sdk. i deinstalled drivers and sdk via install manager, then went to windows/system32/ delted 3 files (amdcpl64, amdcplcl64,Opencl or so) and the same on systemWOW64 or so. Reinstalled sdk 2.5 and driver version 11.11. im pretty sure there is no 2.6 sdk running, but how can i tell? Did i miss any files?

You can just use Phoenix miner which comes with phatk2.

im very frustrated :(

i tried phoenix already, it gives 266 mh/s now, most likely because it runs on stock clock. How can i adjust clock/etc without any (stupid) tools? (266 on 800mnz would be excellent i guess, making 320 on 975 possible :) ).
I tried deleting any amd/ati file like you said here: https://bitcointalk.org/index.php?topic=63616.0
also installed 11.6.
Now opencl wont find any card except gpu0 (no gpu1,2,3..). Damn, my day is already screwed..


edit: i found out phoenix was running on 970/180.. still only 266mh/s. Thats madness!

Driver 11.11 is fine, it comes with SDK 2.5 runtimes after you find and remove newer ones (which you only need to do once). I use Sapphire Trixx to overclock, but MSI Afterburner will also change clocks and voltage above what the stock ATI control panel allows. I don't know where you got 180MHz ram setting, 350-380MHz RAM will be the peak performance on a 5830 with SDK 2.5.

The phoenix 2.0 config file has entries for each GPU - you just need to copy the working [cl:0:0] parameters to additional [cl:0:1] [cl:0:2] and [cl:0:3] for each GPU.

This is offtopic, futher questions should go to the phoenix thread or cgminer threads.

You need SDK 2.1 for best performance of 5xxx series cards.

I use driver 11.12 and SDK 2.1 on my 5970's and 5870's and you get max hash rates with that combo.

CGminer is also a very easy miner to work with, but people can get slightly higher hash rates with Phoenix although phoenix requires some more configuring as the poster above showed you.

CGminer doesn't require as much configuring for optimal performance.

I don't understand why people are always saying that. I always got exceptional hashrates on my 58xx and 5970 cards with 2.5. It was 2.6+ that stunk for 5xxx cards.

Fixed that 4 U.

I was able to get 0.3 % better performance with SDK 2.1

OP updated, thanks Dani. That's an impressive temp with that OC and 20% fan, nice job.

Thank you for your help, i will post further on cgminer thread.

for the temps: some cards are even lower (63°c). pictures here https://bitcointalk.org/index.php?topic=7216.msg1131595#msg1131595. i also applied new cooling paste last month.
if overclocked to 975/300 (1.128 V) the system is getting way hotter (like 73-74 on avarage). keept it cool :)

edit: i fixed it! i was thinking vectors 2 isnt working, but i tried again: it works now. it works as it should :) im so happy right now  ;D
