Recently bought a R9 280x Vapor-x, a small switch (blue when activated) can load bios 1 or bios 2

But haven't see difference on gpu/ram frequency oO

J'aurais voulu savoir si il était possible de réduire le nombre de stale share lorsqu'un nouveau block est trouvé sur le reseau.
J'ai fait quelque recherche avant de venir poster ici mais malgré le faite que le serveur auquel je me connect à un ping relativement bon je ne sais pas trop sur quelle valeur jouer dans le fichier de conf ?
Mon % de rejet est entre 1% et 1.2% sur une période de 24h ca dépend des jours...

L'intensity pourrait-elle jouer un role la dedans ? le faite de poussé un peu trop le hardware ?

Merci d'avance
7  Other / CPU/GPU Bitcoin mining hardware / miner-scr v0.8 BETA (A screensaver using phoenix as backend) on: June 20, 2013, 06:32:56 PM

I'm not the owner of this project but I think is still interesting to post it there

This can be easily updated since I think the owner has stopped the development and ported to litecoin mining with the available source

When system is used, mining is performed with low aggression, to prevent screen lags and performance issues. When screensaver is running, mining is performed with high aggression.

Both, CPU and GPU mining is supported.

Screensaver either shows mining statistics or just a black screen. (This is useful for some displays such as LG E2750, which turn off the backlight on black screen without turning off the HDMI sound output.)

Que ce passera-t-il lorsque tous les bitcoins seront en circulation ? les miners qui était jusqu’à lors récompenser pour faire tourné le réseau n'auront plus aucun intérêt a dépensé des W pour la vérification des transactions ?  Huh

11  Other / Beginners & Help / BFGMINER with 7950 & 5870 on the same rig ? on: May 14, 2013, 03:28:09 PM

Currently I'm running BFGMINER (diablo kernel) with my 7950 with good result ~630mh/s
But I have a possibility to have a 5870 old card gift by a friend
It's possible to run 2 separate instance of bfgminer ?

When I'm off (work or sleep) 2 cards run

When I want to play battlefield 3, watching video etc... I turn off the 7950 but the 5870 keep going ?

Thanks you in advance

Salut à tous, nouveau dans le monde du mining j'aurais une question concernant diablo miner sous windows

Un message d'erreur apparemment concernant java (j'ai pourtant bien installer la dernière version) lors du lancement de celui ci

DiabloMiner-Windows.exe -u xxx -p xxx -o -r 3333 -v 1 -w 256

Si quelqu'un à eu le même soucis...
Merci d'avance
