azndragon328 Posted January 23, 2004 Posted January 23, 2004 whats bad about having your agp /pci over 66/33? mine is currently 70/35, what would happen if i leave it like this? if its @ 66/33, i would not be able to OC Share this post Link to post Share on other sites More sharing options...
Some_Guy_ Posted January 23, 2004 Posted January 23, 2004 Think of it as overclocking the buses. It puts your cards (and your onboard IDE controller) under stress. It can cause data corruption in some cases. 70/35 is fine, in my opinion. 74/37 is really pushing it, I think. Anybody else's experiences?

caffeinejunkie Posted January 23, 2004 Posted January 23, 2004 with my agp at 70 i could just get a 10mhz overclock on the core before i got artifacts. When i put it back to 66 i got 100mhz overclock before i got artifacts. Share this post Link to post Share on other sites More sharing options...
Eva_Unit_0 Posted January 23, 2004 Posted January 23, 2004 Just as everyone else said, it simply causes problems. Typically us overclockers think of faster as being better...that is not the case with agp/pci bus speeds. Pci and agp cards are designed for a completely standardized clock speed, and even a little variation can cause instability. However, don't let that stop you from overclocking or anything. Locked pci/agp clocks are a new thing...we all overclocked back in the day with unlocked bus speeds, and apparantly it didn't do anything TOO bad, right? As long as you're stable, then don't worry about it. But if you increase your overclock some more and it becomes unstable, it's entirely possible that the cpu isn't the thing causing the instability...it could very well be the pci/agp devices instead. So basically unlocked agp/pci clocks just add another variable you have to take into account when overclocking. Share this post Link to post Share on other sites More sharing options...
exeter_acres Posted January 23, 2004 Posted January 23, 2004 good posts..... and to add one more thing.... upping the AGP/PCI bus is NOT the same thing as overclocking your video card... some cards are affecting more by running the bus out of spec... PCI NIC cards seem to be some of the worst.... some video cards handle a screwy bus speed better than others... I will say that like ANY overclocking...the risk is that you could fry something Share this post Link to post Share on other sites More sharing options...
ShadowPaktu Posted January 23, 2004 Posted January 23, 2004 i think that all pci cards can handle either 33mhz or 37.5mhz, now sure bout the agp bus tho. Share this post Link to post Share on other sites More sharing options...
Some_Guy_ Posted January 23, 2004 Posted January 23, 2004 i think that all pci cards can handle either 33mhz or 37.5mhz, now sure bout the agp bus tho. I fried a NIC at 36 once. Didn't matter much, I had a pile of them. Share this post Link to post Share on other sites More sharing options...
ShadowPaktu Posted January 23, 2004 Posted January 23, 2004 whoops, i reiterate the words 'i think' but im pretty sure most new ones support those to speeds :/ Share this post Link to post Share on other sites More sharing options...
Lyrical Exercise Posted January 24, 2004 Posted January 24, 2004 well what if you lower the bus wouldnt that help putting some more mhz out of your video card and also the voltage i never messed with the voltage just wandering if any of you put it up and if it helps out- Share this post Link to post Share on other sites More sharing options...
ant84 Posted January 24, 2004 Posted January 24, 2004 pci over 38 meant loss of all data in my case.... Share this post Link to post Share on other sites More sharing options...
BeatRyder Posted January 24, 2004 Posted January 24, 2004 I can adjust my pci/agp speeds indepenantly from the FSB, but I have them set at default speeds. I dont really understand why you want/need the ability to alter them Share this post Link to post Share on other sites More sharing options...
