I've got my 560J o/c'd @ 4.41Ghz (prime stable for 5 hours). I can go to 4.52 but its only stable for 1-2 hours. I cannot for the life of me get further.

It either BSODs during windows startup progress bar or just as it reaches windows log on.

My vcore is 1.600. I can set it higher (up to 1.725/1.750) but it still wont o/c any further or stop the BSODs.

I've upped the NB/AGP to 1.7v and even 1.8v to no effect.

I found that my FETs were very hot so I sinked them, to no effect:

Does anyone know of anything else I can do? Or if there are any BIOS patches etc to add FSB VTT options etc. I know of a NB Volt mod but I really want to avoid it if I can lol.

Ultimate thanx people :worship:
 
Have you checked out the DFI forums mate? They have a beta bios over there as i remember, that some people have been reporting allowed them to OC a couple of mhz more.

Also, what are ur mem timings? Because even if you know your RAMS limits, its a totally different ball game with the 875P-T - its totally brutal when it comes to memory.
 
i've tried every official bios and am currently on the latest version. None of them made a difference. I've not tried any of the beta BIOSs tho.

My Timings are 2.5-4-4-8, but i've also tried 3-4-4-10, the loosest available to no effect. Is it just a case of me needing to go sub-zero for the components to be more efficent at o/c'ing?

Take a butchers at www.dfi-street.com, they get the beta bios's there first.

Apart from that, you could try lapping your P4 heatspreader to get a couple of defrees drop, that may allow you to push a couple more mhz outta it.

Apart from that, i think you've hit the ceilin :(
 
The 875p-t will run 266fsb easy so its not the mb holding you back, and it looks like your memory is good.The only thing you might try is to disable cpc/addr control in advanced features.

Good luck.

All of my 775 cpus have topped out at 1.65-1.7Vcore and dont like any more Vcore.
