Title: Host Burn-In mode
Post by: EEVIAC on November 09, 2009, 11:52:35 PM
I've got a Pent. 4 641  (SL9KF)        Motherboard  Intel  D945GCCRG1



My bios allows "Host Burn in mode" but when I set it to +4% and boot the computer, CPU-Z shows that FSB speed and Processor Speed at their regular speeds...no increase

Could this be because Intel locked the cpu and/or FSB from being overclocked?

Why would you want to overclock an older system?

Most machines become accustomed to the power accorded them over time, overclocking an older machine can kill it really fast.

It's not that old of a machine.   I got it in the middle of 2007..

if you use the AGP/PCI Burn-in Mode BIOS feature to overclock the AGP and PCI bus, Intel automatically disables this BIOS feature and you won't be able to overclock the processor and memory modules.

That is an old system for OC.

I don't even recommend OC on a new system.  OC causes heat and power issues which kill hardware.

I realize this...   PCI/PCIe burn in mode are currently disabled

Well, thx for the pointer...didn't realize my system is relatively old

I'm still curious as to why no speed increases are apparent  ;)

Because the hardware is not capable of it without failing entirely.

This is nonsense.

I tend to agree.

I was recently able to overclock my old 350Mhz K6-2 to 400Mhz using the jumpers, and it had been running at 350Mhz for nearly 9 years. I did however have heat dissipation problems even with the new heatsink, and resulting errors.

I then replaced the CPU with a 500Mhz model :)

No, actually I've seen it.

They don't get used to being overclocked... that's just silly.

By the same token could one say that running a 100 watt light-bulb at 60 watts will eventually make the bulb unable to output 100 watts?

Additionally why stop at while power is applied, heck, if you leave a CPU untouched for years should it not get used to having no power running through it? what metric is used to determine "when" the chips "power memory" is being affected?
