Been working my way up through the clocks on my e6600, stressing the setup with Orphos blend. Got 1.375v going through the chip in bios (1.352 in cpuz)

2.7GHz is solid, 14 hours of orphos fine, 2.85 seemed fine, ran for 3 hours before I bumped it up to 3GHz to prime overnight.


Set it off running and leave the room for a bit, come back and its still running orphos but the mouse and keyboard aren't giving any response.

Restart and set it running again, again about 20 minutes later I loose mouse and keyboard.

Both times orphos has carried on running fine, another time I was watching a film (with orphos in the background) and the mouse and keyboard crapped out, film carried on running fine.....



Can't think of any explanation for this, anyone got any ideas what could be causing this?
 
My memory was running quite slack, probs in the region of DDR666 at 4-4-4 timings.
Next time will run with really really slack timings just to see if that narrows anything down.
 
USB, or PS2 keyboard/mouse... Perhaps the USB controller (or PS2) are having issues with your overclock.

Do you have the latest bios for your motherboard, and/or can you increase the southbridge voltages (where the USB controller normally resides on many modern motherboards)

Could be completely wrong, but as you say that movies etc keep on running, and so does orthos, I would say that pretty much rules out memory, or cpu issues.

Also as Van says, you shouldnt need that Vcore for 3Ghz, my E6700 does 3.1Ghz at 1.2V (the VID for Conroe processors is set on a batch by batch bases, so the default voltage will vary from chip to chip. My E6700 defaults to 1.2V, I gather some go even lower).

that's pretty weird?

And you say this issue doesn't appear when running at stock or mild overclock?

at 2.7Ghz it was rock solid 14 hours on Orphos Blend. priority one, most o that time was solely Orphos, a few hours of it I was browsing the web.

Will try a lower vcore at some point.... can't see that helping solve this though.

But no harm in trying, might make my temps look a bit better in comparison to other peoples though.

Will give the southbridge voltage a go, may as well up the northbridge too, I just find this really irritating. Atleast when my DFI Expert crashed I'd get some sort of clue as to what was wrong.



Don't think I;m using the latest bios, haven't looked since buying it on the MM, will give that a shot too.
 
PS2 mouse/keyboard problems are a known issue on 680i boards when overclocking, but looks like you're using a P5B and I haven't heard of this on other boards. Tried using a USB mouse/keyboard?

I'm using a usb mouse and keyboard, have tried plugging in a PS2 mouse after is has locked up aswell as another usb mouse.

Will try upping the voltage on the cpu and see if that helps along with trying some different settings in bios......
