p.s. system specs are as follows

GPU-hd 2600 xt 512 mb ddr3 power supply 450 watt motherboard is -ECS mcp73t-m3 REV :1.0

It depends on the motherboard. The only option you have is to overclock in Windows, which isn't a very good option. The best thing you could do is get a different motherboard, but I'm since this is probably an OEM system, you'd basically be building the entire system. So, you should build a system for overclocking, instead.

not what i wanted hear . its not an oem system however.i was given the board a long time ago and built the system myself.new motherboard would be nice but if i had the cash for that id prolly just go get a new CPU lol.anways..i figured that id be more or less screwed on OCing this thing*sad face*

click those white jumpers ... wait its not 2001.. gosh darn the past was usefull
