Having problems getting 500fsb stable on my e8500. can anyone help? this chip is stable at 485*9.5 btw.

I have 4x1gb OCZ 8500 SLI ....easily do 1186mhz @ 2.16V actual

Try these mate :

I would try higher FSb mate as I needed 1.3 to get 4.5 stable on my E8500... but each CPU is different...

Try the above to see if we can get 500FSB stable ( I would set 7 multi ) try to go as low on the Vcore as possible ( I usually test 30 minutes Small FFT, if all passes, I lower Vcore one or two notches and test again, till it fails, then I up two more that should keep it sort of stable)

First thing is to get the CPU stable then tweaks later on

Sorry for stupid question, where is located NB on P5Q Deluxe?

It's under the heastink that is just below ya CPU (with the blue Asus logo on it)

You might want to flash to 1702m, Im having good luck with it and have heard nothing but good things.

Some people claim that they can use less voltage with Ket's bios than the vanilla one, I'm very sceptical of those claims... as his biosses did nothing for any of my 3 boards... but his biosses added ram support tables which can help out others , but if he modified the voltages etc dunno bout that... Form 1611 on I could drop a notch lower on the Vcore but that was a vanilla one
