Title: X11 Mining with Powercolor R9 290 TDHE Problem
Post by: brigada14 on January 06, 2015, 07:09:29 PM
Hello to all,

I have some major problems with my http://powercolor.com/es/products_features.asp?id=544 (http://powercolor.com/es/products_features.asp?id=544)
Most of them are brand new,used few months but they got problems from the beginning
OVERCLOCK: 975/1250 and even less then 900/1050

They get sick/dead 1-2 from 4, Blackscreens, freeze...,sometime it starts with 3 cards... but maybe my extension cable are not goodhttps://www.google.bg/search?q=extender&source=lnms&tbm=isch&sa=X&ei=eTGsVIW0D6W8ygOMgoKYCw&ved=0CAgQ_AUoAQ&biw=1280&bih=615#tbm=isch&q=gpu+extender&facrc=_&imgdii=_&imgrc=7Wvra-MqjoFqqM%253A%3BUU3z36utlzufBM%3Bhttp%253A%252F%252Fdib-bid.com%252Fgallery%252Fpci-e-1x-to-16x-extension-cable-01.jpg%3Bhttp%253A%252F%252Fhashcat.net%252Fforum%252Fthread-1044.html%3B700%3B1600 (https://www.google.bg/search?q=extender&source=lnms&tbm=isch&sa=X&ei=eTGsVIW0D6W8ygOMgoKYCw&ved=0CAgQ_AUoAQ&biw=1280&bih=615#tbm=isch&q=gpu+extender&facrc=_&imgdii=_&imgrc=7Wvra-MqjoFqqM%253A%3BUU3z36utlzufBM%3Bhttp%253A%252F%252Fdib-bid.com%252Fgallery%252Fpci-e-1x-to-16x-extension-cable-01.jpg%3Bhttp%253A%252F%252Fhashcat.net%252Fforum%252Fthread-1044.html%3B700%3B1600)

AND ADATA 64 GB SSD,
Intel dualcore cpu 2.7 GHZ
Using 14.7 drivers,tryed also 14.6,14.2 and i only didnt checked 14.11
Also tryed win7 64bit,win8.1 64bit..
I have also powercolor r9 280x but i dont have problems with them.

SO 4 R9 290 TDHE WITH H61PROBTC,1300 EVGA G2,4GB RAM,CHINESSE EXTENSION CABLES,
I m keeping them on 85-94 temperatures on x11 sgminer,checked a lot of versions... :) from 3 - 5.1
They mine fine,but the question is why i have so much problems, from 15 machines i got problems with 8-9 of them / sick/dead/freeze/blackscreens?
Somebody tryed that cards?
Any opinions?
