Topic: 5830 ONLY AT 270MHash/s (Read 2780 times)

Also some cards (especially the cheaper ones) have very limited adjustment range.  If you adjust outside of what bios allows the card will simply ignore it.

Ahh, then its either a clock/voltage that it doens't like or something else is amiss. Do you have CCC installed? That would do it, as it will override most 3rd party apps changes. I would try using that Trixx utility I posted. It is much more accurate for ATI cards than AB.

The file doesnt change back.  Afterburner lets me change the settings,  but its when i hit apply the core clock and the memory clock go back to zero. 

  Just to make sure I am understanding you correctly, after you edit, save and close the file and then open up afterburner again it is changing the file back? If you are keeping the AB program open while you are editing the file it would likely change it back. Make sure you close AB, edit the file from an Administrator acct and then close and save it before running AB again. 
  If that does not do it try using a different app to OC with. Like Trixx; https://www.sapphireselectclub.com/ssc/TriXX/TriXX.aspx

When I do this it lets me change the clocks but when I hit apply it goes back to zero.  Not sure why.  Can anyone help.  Thanks.


Here's the section you need to change in the MSIAfterburner.cfg file:

[ATIADLHAL]
EnableUnofficialOverclocking   = 1
UnofficialOverclockingEULA   = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode   = 2
AccessibilityCheckingPeriod   = 0

I apologize if what I had said made it seem I was trying to suggest Bitminter of cheating. I do not personally feel they are but was only wanting to point out that it would be possible with the small percentage increase making it nearly impossible to prove without one wasting a lot of time trying to verify and calculate. My main point, and I should have been much more clear was simply that Bitminter was not necessarily the solution to the OP's issue.  I will say you two certainly debate better than I do.  Thank you, Death for explaining the technical aspects much better than I could of my paranoid suggestion. And thank you, P4man for defending what was perceived as an unfounded accusation from my suggestion against Bitminter.

 Now, has the op tried any of the other miners to see if he can get a better hash rate? Also, OP have you checked your task manager to see what your cpu usage is at while mining. It should be very low, 1% or less with most GPU miners these days and would indicate an issue with your miner of choice if it is much higher.

 Guiminer is not an actual miner, it is just the interface to allow you choice of several different miners. If you check the part where is says 'Ext. Path:', just above the server pull down menu, the very last thing will be the miner executable. I.e 'phoenix.exe', etc. Knowing what that is might help better determine where your lower hash rate issue is at exactly.

Agreed, but dont forget you can use a different miner on the same pool. If the bitminter app artificially inflates its reported hashrate, the pool operator would lose money to people using different miners that report accurate numbers. Or am I confused?

If you are inferring he could lie about the numbers of shares per block (something I think you can verify, but feel free to correct me on that?), then you could make the same argument for any pool.

Im hardly a bitcoin expert, but as I understand it, in order to fake the hashrate without him losing money in the process, there would be a mismatch between the number of accepted shares as seen on his pool statistics page, and what I see on my client. Either that, or a mismatch between the hashrate and the number of shares processed. Either would seem trivial to check.  Its also not likely he is using fake rejected shares to boost his hashrate, as I currently have zero rejected out of 1100 shares (dont know what it was before I had to reboot to switch OSs, but its low).

Anyway, nothing wrong with some paranoia, but it doesnt seem fair to make such accusations without proof or even probably cause. Its not like bitminter is 2x faster.

Displaying a slightly higher hash rate would not increase your accepted shares rate. just sayin. ;p

Only sure fire way to test it would be to test say 1k+ share submissions with another site with same card settings against that one...

I thought it wasnt. But maybe Im wrong. Either way, if he is cheating with his hashrates, its an expensive lie since I get paid for my hashes whether I use his client or another.

interesting, using linux (BAMT) @995 core and 325 ram I get around 322Mh/s

Bitminter isnt opensource. If you like, you could reverse engineer it, its just non obfuscated java code, but it might be illegal to use that code. As for the hashrates being accurate. If they are inaccurate than he is paying me too much I suppose in theory its possible, but it seems unlikely for a lot of reasons. Feel free to scrutinize his app, if you find something you'll destroy his credibility and business. I dont think you'll find any foul play.

You have your memory clock @ 1300 ? If, that is correct.....why so high? Also, I am using GUIminer as well. Extra Flags: -v -w128 -f15

I have a 5830 (Non-Extreme version) GPU/980, Mem/600 GPU Voltage 1174 with 303.8-308.3 Mhash/s

The other 4 5830s I am running are the Extreme version, also using GUIminer, same flags, lower voltage, higher GPU clocks 990-1000, Memory/350 and they are
all avg/around 310Mhash/s

I use Trixx with 940/1300 and get around 260 with win7 and guiminer. I haven't tried phoenix yet since I enabled OC.

True up until bitminter.. Only because I'm wondering if anyone has checked their lil java code to see if it is just adding a few %hash to the reported hash to make it look faster? It just seems otherwise the mining app writers here would have snagged up the optimizations by now...

Still, his hashrate is a tad low for his clocks. I found diablo to be faster than phoenix on my 5850, and bitminter (https://bitminter.com/) to be a tad faster than diablo even (and a lot easier to use). But mitminter's mining app only works on bitminters pool but that isnt necessarily bad, considering the freebies they are giving out. Bitminter is a java app launching from the browser, so its easy to give it a try. Be sure to click the tweak button and set the interval to 10 or so if you want a responsive desktop.

+1 High 900's should be attainable without too much difficulty. Try memory at 350.

I had trouble with this too at first...  but BEFORE  you try and edit the file, you have to change the permissions of the file to give yourself write access.

the first time I ran into this, afterburner was using a copy of the file that I couldn't see after failing to save the edited version. I ended up uninstalling and reinstalling afterburner to fix... 

Have you quit the app you're running before trying to edit it?

Im trying to edit it and it says acces denied.
