8800 GT Overlocking

I’ve been looking for the highest working overclock for the Zotac 8800 GT Amp and now I’ve got some results. Originally the card was 700mhz core,1700mhz shader and 1000mhz clock. I pushed the card to perform well with 728/1812/1061.

To increase the fan speed to 100% and set clock frequencies I’ve used RivaTuner. I use Atitool to scan for artifacts, and play some UT3 to test stability. I should use Crysis, but I’m too lazy to install it. Anyhow this testing method works rather well, and I’m surprised at how far the Zotac can be pushed.

I need to do more teting, since the memory can most likely be clocked more. I’m using my older pc to run the tests, since my new motherboard is screwed (messed up bios), but when I get it replaced I’ll have more detailed info. The ga-ex38-dq6 gives me a more stable overclock aswell since I can increase voltage for stability etc… It’ll be interesting to compare the 8800gt to the 9600gt once I have more results.

Root, the source of all good and evil…

Just like a hero, being root requires great responsability… this should never be forgotten. Today I made a big mistake. I was about to remove a directory from /usr/share/, so I typed in rm -r /usr/ – and then accidently smacked enter. Initially I got petrified thinking that I had only typed rm -r /… but then I realized that my important unreplaceable files could be rescued… annoying nevertheless. The incident got me pondering about how carelessly I proceed with my root actions after typing su, something similar is bound to happen someday if I’m not careful, possibly having a worse outcome. Have to watch out more.

EDIT: I now have added a remove y/n promt through .bashrc

Conky configuration for XFCE4+Compiz

Lately I’ve been very interested in monitoring my system, mainly temperatures. When I use Windows I like to monitor temperatures with realtemp and to monitor my linux temps I use lm_sensors.

Constantly typing in “sensors” in terminal to view the cpu temperature got me a bit annoyed. So I installed Conky, a fancy configurable monitoring program that sits on your desktop and displays system information. However, even though Conky was easy to install and configure to display what I needed, making it work properly in the XFCE4, Compiz and Avant Window Navigator scenario turned out to be very difficult.

When I looked for solutions I found many, but none of them worked with my setup. The problem was that with any ‘default’ .conkyrc from the Conky website, Conky would dissapear when I opened any window and minimized it. I tried some own_window variables but there was always a new problem when the old one was fixed. Finally I though I had found a working config, but no, Conky would flash from beneath windows every now and then, making, for example, Firefox browsing very irritating. Finally I figured out the culprit, it was own_window_type. The workaround was to completely forget own_window_type and only use and arsenal of own_window_hints. Here’s what worked for me and I have a feeling that it could work for others having the same problem:

double_buffer yes
own_window yes
own_window_transparent yes
own_window_hints undecorated,sticky,below,skip_taskbar,skip_pager

See there’s no own_window_type. Amazing when all the possible solutions that I ran into had something to do with own_window_type, e.g. own_window_type desktop or own_window_type override. Now Conky works fine and I can move to calibrating the sensors output. Please comment if this helped, or if you need help 😀
