We're talking about an RDRAM system here, so overclocking is probably going to be limited. This sort of thing really deserves its own thread.

I just finished building my first pc. I have a 2.8GHz Prescott P4 with HTT. I have been able to oc it 3.5GHz stabily by just uping the FSB. I can not find any options to up my Vcore. it is still running at the stock 1.44v This computer was built from a compaq computer I had before. The only things that are still from the compaq is the case and the PSU. The PSU is a 250 watt POS. Is the power supply the resone I cant find any option to up the Vcore? Is the Vcore an option in the Bios or is it changable in the PSU itsself or what. Thanks for your time and you did a great job with this guide. You helped me out very much. Thanks

Also I wanted to add that I have no cooling problems. My Cpu runs at 25C~30C gets to about 35C under heavy load (playing doom 3 for a few hours) Also I dont have any of thouse cool testing stuff for stability so I use doom 3 as my tester lol. If it runs that with no problems then all should be fine right?

the vcore should be an option in your bios. there are no i/o's in the psu except for voltages. do a search either on google or on the boards for prime95 and you should be able to download that program. let it run for at a minimum of 8 hours and let us know how it helds up. with that vcore, i dont think it'll last that long, but good stuff so far!

I read that guide you posted on here and when I go into my BIOS everything is greyed out but I dont know how to select manual settings or whatever...do I need to update my BIOS or am I just dumb....I belive my BIOS is Phoenix Award-BIOS? Something along those lines. Thanks


**Update**

Phoenix-Award BIOS v6.00PG
BIOS Date: 05/19/03
BIOS ID: 05/19/2003-i845G-W627-6A69VM4WC-00

What is your motherboard?

you may not have the options to overclock.

Alright I got a new PSU. I chunked the 250 watt guy out the window and put in a 500 watt Mirage DR-B500E in there. It has neet little lights too hehe. But I still have no idea how to up my Vcore. I ran Prime95 for about 20 hours with no errors. Im currently clocked out at 3.5Ghz from a 2.8GHz Prescott. Not bad im sure but I know I can go farther if I am just able to up my voltage. I have plenty of room for heat. it runs at about 35C under max load. (Its a bad mofo liguid cooling system that hooks to my cpu and gpu and stands like 4 feet tall.. Sorry I dont know the name... Its writen in Japanese hehe) under normal load my VCore is at 1.440v and under max load it drops to 1.400v to 1.390v. If memery serves me right I belive the max for these chips is around 1.525 or so. If I could bump it up a little I know I could make it stable around 4.0GHz. I hope someone can help me out.. My mother board is a Giga-Byte GA-8IG1000MK. If you need more info on my PC just look at my specs under My Rig. Thanks.

I originally bought a prebuilt computer (HP) before i really got into computers and I've been slowly just adding better stuff, so I'm not sure what motherboard it is and I dont know how to check it...so....what is the best way to check what board it is?

Mashif

If you havnt changed the Motherboard out then you will not be able to oc that system. HP's are locked. Sorry mate. But the good news is a new mother board isnt that expensive. You can get a really nice one that will blow your HP one out of the water for about $100 to $150 US dollars. Just when you do be sure that you match it to your case and the equipment that you already have.. meaning if you have a socet 478 prescott be sure to get the right one. Also if you have a PCI-E or AGP 4x-8x video card be sure to match that as well. Everything else will pretty much fall into place. What I mean by match it to your case I mean like if it is a normal ATX (with 5 PCI slots.. Tall box) Or a MiniATX (3 PCI slots.. Short box) More then likely it will be a mini if its a normal HP machine. But just check to be sure. Hope that helps you out a little.
