Overclocking Question

[Corey0808]

I tried overclocking my Barton to 3200+ todya on my NF7-S V2.0 Motherboard. I bumped the mem voltage to 1.7 and the processor to 1.725. It started upand I got to the windows log on screen and when I hit ok it continued to start up and then all of a sudden it powered down and restarted. Is this a power supply problem? Thanks for the help

no it proubly means 1 of two things it over heated, or you don't have enough voltage going to the chip. what temps are you running?, Also the NF7 undervolts the CPU by about .03-.05V so in reality 1.7 is about 1.65 which is stock voltage. I'd bump it up to 1.8-1.85 should be fine. if it runs fine at this voltage start up Prime95 and monitor your temps as long as they stay under 55 under full load and Prime doesn't error out your good to go.

your ram is good enough so thats defenatly not holding you back, what PSU are you running?

Just a crappy 300W power supply... I'm thinking of getting an Antec True430 though... How do I tell if my Board is undervolting?

I bumped the vcore up to 1.75 and it booted. I got into windows and then on two occassions it would lock up with no warning a couple minutes after boot up? What does this indicate?

Also I just noticed I ran CPU-Z at stock voltage and it alternated between 1.632 and 1.48 most of the time and I happened to take a screen shot when I was at 1.75 and it said I was at 1.712. Does That mean my power supply is going because it can't keep a steady voltage and that might be why it wasn't stable?

well the fact you could actually get too windows on a higher volatge means thats helping the problem. but if the volatages are varing that much defenatly get your self a new PSU either a Tru430, although I had mine blow up on me a week ago so I would proubly just go with a Fortron 500Watt. load up MB Monitor that iwll give you an idea of you tempatures. bump the volts up too 1.8-1.85 its sound like you have a stuborn chip but should hopefully be all you need, with a new PSU you might even be able to get stable at 1.75 but no way too tell till you get the PSU.

Currently I've hit a wall at 2.53GHZ on my rig due to my backup Fortron 350 not being able to put out enough power. as soon as I get my RMA'd tru430 back I think I'll get another 100mhz outta the chip

Thanks for all the help. My birthday is coming up and I'm going to get a new Heatsink and Fan (SLK-900A with a Panaflo) and some new case fans (Vantec Stealth) and I'm gonna add a power supply to that list. I'll save my overclocking for then I don't trust my power supply because it seems like the voltages are varying way to frequently to hold a stable over clock. At 1.65v they will go as low as 1.612 and don't go over 1.648 so I think that's a power supply problem. Thanks for the recommendations and if you have anymore please let me know

I have a barton 2500+ on a ASUS A7N8X dlx. rev. 2 and i run below 39 idle with a 900A heatsink and a vantec tornado, of course i have a fan controller for it. But i would just raise voltage up to 1.8 and ram to around 2.8 fsb to 200 and just keep raising the multiplier or keep multiplier low and raise the fsb little by little.
