Pool stable version of Bitcoin Core: This is an archived post. I'm getting kh's with the same cards. Sapphire in or sign up in litecoin. Let us look at how to configure the PowerColor R9 280x for higher hashrate and possibly lower power consumption.

On win7 x64, updated ati catalyst driver and finally got my cards up to and kH. TaintedSquirrel , Mar 16, Could you post your exact config? I know it is possible to have them running higher but with normal settings they will life longer. The vapor-x is the third one in the values. Log in or sign up in seconds.

Also power tune at Sapphire downgraded the hell out of the Toxics. Would it be considered too high a risk to clock it that far? I'm running these settings: My settings are similar to most people apart from the gpu engine, which i've clocked to It is probably the top card on the market in this category.

I wonder how long until the Vapor-X Tri-X cards gets downgraded to elpida? I hope Maxwell fucks up AMD. Nitron , Mar 22, Mar 22, 8. I don't think the card itself even monitors VRM temps so I doubt it would even throttle itself if I were hitting C on them but I have no way of knowing without a thermal gun.
Sapphire bins the Toxic chips higher, and afaik your voltage is unlocked to 1. I can't adjust mine at all, it's permanently locked at 1. Apart from the cooler, the Toxic is better in every way.
But they're still closely locked down. Out of curiosity what are your VRM temps? Both cards use similar VRM cooling. Thanks dude you're a hero. TaintedSquirrel , Mar 22, Mar 22, 9.
That was one of the reasons I pulled out of buying this card. I noticed the gap between the input grill and the heatsink was different than the Toxic.
Notice the gap in the pic below: It is probably the top card on the market in this category. If you just game and do video and aren't mining, then you have little to worry about. Be glad you have a hynix card, I would probably trade you straight up for my Toxic Tri-X.
I have read on a forum that they nerfed the hell out of the bios on the new Sapphires locked? I have not done any bios changes or testing yet. Mar 22, It's so good I almost don't trust the sensors. I pulled the heatsink off mine the day I got it, so I needed a way to verify I re-installed it properly. January 23, , Im trying this setup in the OP on a saphire x and it doesn't show my GPU temp, but if i just use a basic script the temp shows is there a command in the OP's config that stop the temp from showing?
I think i figured it out Team viewer or VNC is required. PM me if interested with details about your system. After days of problems with one of the cards overheating the following settings work best for me. Use a manual overclocking tool like Sapphire TRIXX will let you set individual cards separately too , and set the fan at a high enough speed that it won't overheat at load.
CGMiner, when it's adjusting settings on the fly will go lower than it should, as it doesn't realize that the r9s can operate in the higher temp ranges.
I keep my at 80 degrees with the fan set at a static rpm. Now use the scrypt mining tweak guide in your cgminer directory to tune it, and you should be good. Also note, depending on what pool and what coin you are mining, it can sometimes make a kh difference, so choose a pool with good connection speeds. January 30, , You can find the conf file, called example. CD into the cgminer folder and type: Can you tell me if this is my best hash rate and if not how can i increase it? February 07, , Hi Guys, I have recently bought a sapphire radeon r9 x for litecoin mining.
I tried playing with thread concurrency and set it to , also set memclock lower but none of those help. Also i heard about undervolting the card, but i am not really confident doing that. My settings are just --thread-concurrency -I 13 -g 2 -w --gpu-fan 85 --lookup-gap 2 --gpu-engine --gpu-memclock --expiry 1 --scan-time 1 --queue 0 --no-submit-stale.
Full Member Offline Activity: December 28, , Typically you'll have a problem in multi gpu configs. My card gets khsec in a single config but hashes poorly in a multigpu config less than and no better than khsec. Flashing the card to an earlier bios say Cards with this bios version don't have this problem.
Maybe dumping the existing This is just a guess. Also pressing the sapphire button on the card so it operates the bios may help, I haven't tried yet will give this a shot tho. After investigations its due to the vrms running really hot over c. Sapphire has been contacted but won't fix it and says the temps are acceptable: To fix it yourself, you may swap it for a toxic edition which has heatsinks on the vrms vs just heatpads that the vaporx uses.
I'm going to try increase the TDP e. Sorry to be the bearer of bad news if you aren't aware of this. Any suggestions for finding and fixing the problem? What happens when it crashes?
