Can anyone tell me any specifics on what method Claymore uses to get gpu temps?

I'm trying to troubleshoot a 7950 reference card that recently started reporting high temps to Claymore, but aticonfig --odgt fails to retrieve temp (or clocks). Claymore gets the temperature, but the card is actually about 20C cooler than reported temps. It'll hash; and temp seems fine best I can tell with an infrared thermometer on the PCB & comparing with identical cards in the rig.

Anyone suggest a possible fix or route for troubleshooting? I've flashed original bios, i've tried down-volted and down-clocked bios and all get the same overheating results.

I can use claymore's low intensity mode (-li 50) and turn the clocks down to 850, 1000 and use -asm 2 and it'll hash at about 30 sol/sec but says it's 80C and really isn't.

Will the new driver make the mining faster for these cards?

I thought the latest driver does not have the old cards?

Hi guys!

I've come across a weird issue. I have MSI H270 PC mate MB, R270x card, Windows 10, no overclocking. And I updated MB BIOS yesterday. Since that I'm getting "ZecMiner64.exe has stopped working" right after start. Log contains only (even with debug option on):

12:02:19:594   b80   ZEC: 1 pool is specified
12:02:19:595   b80   Main ZCash pool is eu1-zcash.flypool.org:3333

I've used AMD uninstall utility and reinstalled recommended 15.12 driver - no luck.
Can someone help me to overcome this issue? Thank you.

@Claymore, when do you think we'll see a new version? Its been almost a year since your last update. It would also be nice to have the lower dev fee that you promised. Thanks for all of your hard work, its much appreciated.

I don't even try to find out what errors like that mean these days. I just reflash a clean install (I use SMOS for Tahitis) and flip it back online. Fixes the "problem" 9 times out of 10, especially with Tahiti cards.

I spent way way too much time trying to get Tahitis to work right in Linux, Win 10, Win 7 and fglrx, catalyst 15.12, blockchain driver, AMD-GPU (yeah, I didn't get the memo), etc. It was a pain in the ass on every OS and always fragile if I got it working. I use SMOS because it's plug and play for my 7950s. YMMV, but I would suggest you at least make an installable image of your drive as soon as you get the drivers running in any OS.

"Already very fast" compared to what? Do you mean it is already very efficient, or is there some other technical standard you're using? I think that may sound rude, but I would really like to know.

Anyone know what this is?

I've got Tahiti cards and this keeps popping up at the beginning of my logs and not sure what this is. Anyone?

As far as I know, and I have Googled hard, there is no programme (such as Polaris Bios Editor) to modify the memory straps on an R9 270 ('x' or 'no x').
I did modify the memory timings an R9 270x using a hex editor but it made no noticable difference to the hashrate.

If you want to try and hex edit your GPU BIOS this here is the link on how to do it..
