I'm confused, on my Asus P4C800-E Deluxe I go into BIOS and lock my RAM and AGP and PCI clocks, and then I turn up the fsb. I tried for 3.0@3.4 on like 1.550 1.575, 1.6 and everytime when I booted it would say "overclock failed" what the heck is going on?
 
alright, for real whats the problem? Comon guys, this is serious, my OC is on the line :(

P.S. That is the funnist SNL skit of ALL time
 
what the heck are you talking about? Can someone please give me a strait answer?
 
1. Not enough voltage(mine would only boot with 1.66v 230FSB , 1.5vstock )
2. You've gone too far with the FSB(most likely this one)
3. Yeah.
 
Sorry, I cant help you too much sinve I have a INTEL D865 PE mobo that is almost unoverclockable but, if I were you, I would try to overclock without locking the ram, agb and pci. Then see what happens. Try to elimante the possible factors that could be causing the overclocking failure. Maybe you should update or reinstall the BIOS or something like that. If you cant overclock in the end then dont. I doubt you will notice a big performace difference between 3.0 and 3.4 GHz in normal applications expect for some hardcore games. Ok, hope I helped you a little. (Also try to update something like the chipset drivers for the motherboard..........or reinstall..play with those kinds of things)

UP THE VOLTAGE!! maybe that will help!!! (not too much)

Ouch, thats pretty crappy. At 1.6Volts I got 250fsb, although I didn't keep it there.

edit: to Zeke...
So you have your AGP/PCI locked, and your RAM is running 1:1? Or on a divider? If 1:1 your ram may simply not like whatever speed you're running the fsb at.
 
it could be your ram not being able to run at 450mhz with those timings, relax the timings and set the divider at 3/2 fsb/dram

try voltage at 1.675v
or your chip might be maxed out if you tried all of the above
 
Zeke,

Try setting at 1.6Vcore as for me discovering it that, that's the most stable Vcore i have tried to achieve 250MhzFSB with my Hynix Value Ram......or try 1.65 or more....coz our mobo's vcore fluctuates like crazy, it's really hard to tell which volt will it slightly fluctuates or overvolt the cpu......just take this as trial and error.......live and learn and if dont boot.......try upping the volts.....

Like everyone else in here suggested you can try to change the dividers from 400 or 333.........but you need to find out where your ram will max out and and your cpu before you start hoping for higher FSB......

My settings at the moment.......

If you want to test how stable your O'c is just download and run CPUBurn in.....or Prime95.....

Legacy USB Support: Disabled
PAT: Auto =OFF.....Turbo OFF
Dram Ratio: 333
Vdimm: 2.65V
Vcore:1.6V at full load it stays at 1.58V........
AGP Vddq:1.6V from what ive heard this shares voltage to the northbridge
FSB:240
Spread Spectrum: Disabled....

2.6Ghz at 3.12Ghz



Goodluck

It's called the hardforum, and it's be a cold dark day in hell when you aren't allowed to come here asking questions about overclocking.

Zeke, if 3.0@3.4 doesn't work, start with small steps, and definitely try running your memory at a lower speed.

Stick with 1.6Vcore as that is the most stable Voltage i have tested in mine....even the 1.7V+ are complete crap....they would dip all the way down 1.6 at full load and my temps barely rise.

Agp Vddq: 1.7V+ this would feed the northbridge also some voltage to keep you ocing higher.....

vdimm: max this out at 2.85V if your using Dram Ratio of 400 1:1

Vcore: Just stick to 1.6 this will not fluctuate as much as the others do......I couldnt stabilize my 2.6Ghz at 3.3Ghz with 1.725V but manage to run 3dmark01.........

go to this site as they are more helpful to your needs as what i googled with in the last couple of days..... Abx zone and www.xtremesystems.org

Happy Oc'ing
