k i have a barton 2800+ unlocked. (12.5x166) and it runs fine at 13x166 (3000+) but thats all i can do to it without it f ing up,i change the 166 to 168 wont get into windows the 13 - 13.5 wont get into windows, its on an abit at7-max2 and i was wondering how i can go about overclocking her higher.. it runs at 39c idle at 3000+ so the heat isnt a big problem.. any help plz

May be a stupid question, but did you raise VCore?

I would be amazed if he was having voltage problems from a 25 mhz increase off stock spead. I think we have a different problem here. Dr3w, we are going to need all your specs for PSU, RAM, Video Card, and a better description of where the system is failing within the boot cycle. Does it post ?, will it let you back into the BIOS ? Is it telling you somehing is wrong and go to the BIOS and fix it ? etc..

In the mean time, I'll go download your mobo manual. We should get this fixed today, but only if you stay with it, otherwise it'll be a couple of days.

CYA when you get this together

i didnt change the vcore yet becouse im sure thats not the problem with such a small overclock.. well its 75 mhz but anyways still i dont think its the vcore but should i try or ? becouse ive killed this proccesser and rma it with amd liek 3 times already and i tihnk there tired of hearing from me so i dont want to kill it..

Stop right there, you have killed how many procs ?

And how did you kill them ?

I may be getting something wrong here, but I think what he's saying is he can make it run at 13x166, but it won't go into 13.5x166. Now

12.5x166=2075
13x166=2158

So that's 83 MHz right there, 13.5 pushes it another 83, for a total of 166 MHz. In my world this would require serious increase in voltage...

thx for the help man, my specs are in my signature if u need more info post, and ya i bought a 2500+ but iy died alogn with my power supply ( power supply blew) then i got a 2800+ and i overclocked it to 3000+ also and liek a week l8er it jsut died on me.. so i called amd nad they were nice to send another 2800+ for the 3 time nad now im here... and my proc isnt running hot .. as posted i have a fat 500g copped heatsink on it with a big delta fan..

oho and ya it posts.. windows boot screen passes and at logon screen like 4 seconds l8er it just restarts..

ooh and ya it works fine at 13x 166 (3000+)

A 166mhz increase would hardly call for a serious voltage increase in most cases. I have my xp1800 increased 500mhz so far without touching the vcore voltage.

[Edit] Try using the "Edit" button Dr3w, instead of making numerous posts one after the other.

This guy just doesnt care! Do u kill chips as a hobbie or as a crave release? I would deffinantly sort your self out there - DONT OVERCLOCK IT. Youve done neough damage already. Just get a decent antec PSU, unless u already have, check your motherboard settings will not blow it apart, and leave it to cruise.

Dam m8 3 dead 'uns and your still crazy about it.

Well, never mind then.

And Dr3w--I know it's probably not what you want to hear, but maybe you should just leave it at 3000+...

Couple questions for ya....I have the same CPU...my multiplier is locked @ 12.5...how is yours unlocked?

Try this: Set the multiplier back to 12.5, leave the vcore alone (for now), raise the fsb a few digits at a time, see if you can get any better via that method.
Keep an eye on your temp as you do this. We don't want you to RMA another one. As long as your temp is fine, when it gets errors or doesn't boot/post, raise the vcore a little at a time. If that doesn't help, bring the vcore back down, and bring down the fsb a notch or 2 at a time till it will boot.

Run Prime95 and see how long it takes to give you a backhand.

Was it a website based RMA or telephone? What info was needed? I have a dead 1700+ PIB layin around I need to get RMA'd. Would appreciate the info as I don't wanna take it back to where I got it.

nev payne... it was never my fault the first was the power supply and the 2nd amd even said it was a bad processer they wouldent of sent it if it wasnt there fault, and lokieny if u have the the box and fan heatsink then jsut call them they ask for a nubmer ether on the fan or on the processer and u send it to them and they send a better one back with 2 day fedex service.

Edit: Nev payne i was asking for hlpe not for your unnedeed comments, and lokieofny mabie its unlocked suz it coems straight from amd.. both of them were unlocked and bought came straight from amd.

Unholy, your right about the 83 mhz, course that was with the multi, and then he bumps the H-Clock a slight bit and looses it.

It posts, makes it into boot up, windows esentially initializes, and then it reboots.

Some piece of hardware is not happy, something that isn't accessed till after windows initializes. USB comes to mind, doesn't get picked up till after the OS kicks in. I am sure there are others.

And yea, a lot of people are running up their VCore unneccesarily.

My xp2100+ runs at 2.3 gig and stock Voltage, my P4 2.4C runs right now at 3Gig even and stock voltage. All hardware is a little different and they won't all behave the same, but it's just a bad trend and guys need to slow down a little about running up the voltage, often that is not what's holding them back.

As for this issue, I don't have it pegged down yet. I am also suspicious of the RAM settings. What brand of RAM is it, and if more then one module, are they the same model/part number ? Mixed RAM could do this, mixed RAM can do this without an OC.

The brand is Major, and ive always bought that kind of ram, if get my thunderbird 1.33 to 1.6 without any problems with it. and u want the latancies or anything ?, and about that usb.. would it be smart to disable usb in bios nad try booting without it ?

ooh and another thing tihnkin of it, u lock tihngy that i never touch mabie thats it the 3 nubmers there (ex. 5:3:1) u lock the speed of pci and etc.. would i have to change that to anytihng ?

I'd go with better RAM, to be honest. It's probably what's causing you problems.

Ya thats was i was going to do.
