i have a p4 2.8gh C processor on an asrock p4vt8+ mobo with 1x512 2700, and 1x512 3200 ram. i have a 350w power supply. i tried overclocking and i only could get up to 2996mh 210x14fsb. and if i stay at that speed and start playing games or listen to music it reboots and goes back to its default settings. my memory is over clocked to 400mh and its a 1:1 cpu/ram ratio. is there anything else i can do to make my system more stable and be able to overclock even more. cuz thats a ****ty overclock. plus my temp for my cpu is 45c stock hsf and 29c mobo 30c hard drive #2 and 19c harddrive #1 with cooler

lots of rep points for anyone that helps

thanks

3 things....

1. do u have a pci/agp lock?

2. can u change voltages

3. probly wanna change dram ratio lower

this can be anything, but i think its either the psu or that your ram cant go high enough. lower the ratio, thenif that dont work raise the voltage, and if that dousnt either then its probly psu. but if u dont have a pci/agp lock then u wil max out very quicky...around where u are

is it an oem system kiddo? or is it an system that u built urfselff....cause normally u change settings in BIOs and they dont reset unless u reset it...software based overclocking is different and resets and is crappy and made for OEm systems that doesnt work well some times

sorry man but ure a little off. alot of mobos reset themselves if they have unsuccesful OCs. alot of asus' and my abit does it...maybe his does it to...that has nothing to do with OEm, they dont even worry about that cuz it doesnt OC. but OEMs can change what u can do in the bios

thanks im gonna check my bios see if i can find a pci agp lock. i cant change my voltages it seems to me that they adjust everyfew seconds automatically and when i go to change my ram frequency this it wat it says:

166mh
200mh
auto (default)
im using the 200mh setting. (asuming 1:1 cpu/ram ratio?)

is there another way to change my ratio thanks for ur help

well, thats the right thing...200mhz is 1:1 and pci/agp lock should be on same page in bios...it should say like pci freq 33mhz or something like that. if u find it set it on 33, or 66/33

It's your mobo fault for sure, because look what some people managed to do with this cpu:

Ps with my VIA PT880 based mobo i did a ~300MHz oc without vcore changing...
