sjaglin Posted December 8, 2005 Report Share Posted December 8, 2005 I decided to do a bit of research on overclocling in Linux with no much success. I found a program called nvclock though which you will find as an rpm on the 2006's RPM ftp and the tar files on the website http://nvclock.sourceforge.net/ I had a job to install the 0.8 (unstable) version and had to do make install --disable-qt so it installed only the command line which is easy enought to use. nvclock -s informed me of my current settings of GPU clock and memory : Card: nVidia GeforceFX 5700 Card number: 1 Memory clock: 599.400 MHz GPU clock: 300.857 MHz Strange start as gigabyte's vtuner (under winfart) gave me 425/550 and according to Tom' s hardware mother of all GPUs (Summer 2005) I should have expected 425/550. (http://www.tomshardware.com/2005/07/05/vga_charts_vii/Apage2.html). So is the kernel deliberatly slowing down my GPU ? Then I did a few experiments as follow, keeping an eye on the result with glxgear : Memory clock: 551.571 MHz GPU clock: 300.857 MHz Stef@11:40:01->glxgears 11223 frames in 5.0 seconds = 2244.480 FPS 11280 frames in 5.0 seconds = 2255.870 FPS 11294 frames in 5.0 seconds = 2258.716 FPS 11284 frames in 5.0 seconds = 2256.763 FPS Requested core clock: 350.000 MHz Adjusted low-level clocks on a nVidia GeforceFX 5700 Memory clock: 551.571 MHz GPU clock: 351.000 MHz 11230 frames in 5.0 seconds = 2245.929 FPS 11289 frames in 5.0 seconds = 2257.734 FPS 11235 frames in 5.0 seconds = 2246.931 FPS 11294 frames in 5.0 seconds = 2258.777 FPS Memory clock: 551.571 MHz GPU clock: 399.600 MHz Stef@11:42:38->glxgears 11210 frames in 5.0 seconds = 2241.866 FPS 11310 frames in 5.0 seconds = 2261.901 FPS 11285 frames in 5.0 seconds = 2256.873 FPS 11276 frames in 5.0 seconds = 2255.198 FPS Memory clock: 551.571 MHz GPU clock: 425.250 MHz Stef@11:43:36->glxgears 11155 frames in 5.0 seconds = 2230.853 FPS 11271 frames in 5.0 seconds = 2254.156 FPS 11093 frames in 5.0 seconds = 2218.434 FPS 11271 frames in 5.0 seconds = 2254.183 FPS Memory clock: 599.400 MHz GPU clock: 300.857 MHz 12074 frames in 5.0 seconds = 2414.779 FPS 12200 frames in 5.0 seconds = 2439.905 FPS 12182 frames in 5.0 seconds = 2436.361 FPS 12210 frames in 5.0 seconds = 2441.855 FPS Memory clock: 599.400 MHz GPU clock: 351.000 MHz Stef@11:45:32->glxgears 12081 frames in 5.0 seconds = 2416.165 FPS 12202 frames in 5.0 seconds = 2440.226 FPS 12191 frames in 5.0 seconds = 2438.178 FPS 12207 frames in 5.0 seconds = 2441.365 FPS Memory clock: 550.800 MHz GPU clock: 425.250 MHz Stef@11:46:28->glxgears 11218 frames in 5.0 seconds = 2243.523 FPS 11244 frames in 5.0 seconds = 2248.716 FPS 11183 frames in 5.0 seconds = 2236.471 FPS 11255 frames in 5.0 seconds = 2250.824 FPS Memory clock: 607.500 MHz GPU clock: 425.250 MHz 12245 frames in 5.0 seconds = 2448.891 FPS 12309 frames in 5.0 seconds = 2461.684 FPS 12309 frames in 5.0 seconds = 2461.731 FPS 12306 frames in 5.0 seconds = 2461.174 FPS My chosen tuning is therefore (to be on the safe side) 425/600 for which I obtain a score of 30.6 fps on the doom3 demo1 usecache benchmark. I would be happy to hear about anyone having tried anything similar and explain to me the lack of impact of tuning up the cpu compared to tuning up the memory. My system = FX5700 128Mb in an ideq210v DDRam 2x512 @ 2700 and a couple of big hard drives. The cooling is performed by a DIY fan/extractor. Cheers!

ianw1974 Posted December 8, 2005 Report Share Posted December 8, 2005 I have an NVidia GEForce TI 4400 with 128MB ram, and I get around 4000fps and I've not overclocked it. What driver are you using? The one that came with Mandriva 2006? If so, suggest you download the driver from NVidia, and you may find it'll work better without needing to overclock it?

guppetto Posted December 8, 2005 Report Share Posted December 8, 2005 If you include the Coolbits Flag in your Xorg file, you can use NVidia's native overclocking utility in the nvidia-settings control panel. A google search for Nvidia Coolbits for Linux will provide you with all the info you need. Quote Link to comment Share on other sites More sharing options...
sjaglin Posted December 8, 2005 Author Report Share Posted December 8, 2005 Hugh! Very Promessing, I use the 1.0-8174 for the driver (uploaded about a week ago from Nvidia with the nvidia xconfig utility. I guess my results are not very good, I need to find-out what's wrong although I seem to remember the Ti versions were really good cards where the 5700 a medium range when I bought it. I will need to look for the coolbits to see how that goes! Thanks for your help. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted December 8, 2005 Report Share Posted December 8, 2005 I think mine is the 7174 driver, or the previous release to the one you have. Might be worth giving a go. Quote Link to comment Share on other sites More sharing options...
sjaglin Posted December 9, 2005 Author Report Share Posted December 9, 2005 (edited) Hey! I ve done the installation tweak to enable the coolbit function and it works wonders. After installing and rebooting X the overclocking function appeared in the nvidia-settings. 1- It explained why I was getting some weird frequencies to start with : there is a 2D pair of settings and a 3D one! 2- It found my optimal settings : 462 / 631 for which I get a score of 2568 on glxgears. 3- I suspect the score one gets on glxgear depends on the size of the window in which it s running, a benchmark like doom3 demo (35FPS now) is more reliable to compare machines between them. 4- Now I would like to know if there is such a thing as a "software" overclocking utility for the cpu Thanks to all, issue solved and learned a lot!!!

guppetto Posted December 9, 2005 Report Share Posted December 9, 2005 Your welcome! Be careful not to fry your card though; you can push the card past the auto detected limits, but be careful not to set it on fire. Linux, you got to love it!

sjaglin Posted December 21, 2005 Author Report Share Posted December 21, 2005 Hi To carry-on with my query, has anyone managed to modify the speed of their fan on nvidia cards via nvclock or any other software? Stef Quote Link to comment Share on other sites More sharing options...
scarecrow Posted December 21, 2005 Report Share Posted December 21, 2005 Please try 7676. 8174 has a few issues, and (according to all reports @ nvidia forums) is slower. Quote Link to comment Share on other sites More sharing options...
sjaglin Posted December 21, 2005 Author Report Share Posted December 21, 2005 OOPS Sorry, too much work made me miss the -f option on NVCLOCK, it now works marvel with : nvclock -f -F 40 being the best tuning noise vs cooling... Quote Link to comment Share on other sites More sharing options...
daniewicz Posted December 21, 2005 Report Share Posted December 21, 2005 Now I would like to know if there is such a thing as a "software" overclocking utility for the cpu Probably best to do this from the BIOS. Increase your front side bus in SMALL increments (say 2) above the default. A processor with a FSB of 133 would likely run OK at 140 or so. Keep a close watch on CPU temperature. Check stability of the overclock by running memtest overnight after each bump in the FSB. Quote Link to comment Share on other sites More sharing options...
