Kingston @ 1.65v on P55-USB3

Yo Dude! Sounds good to me. The settings can be left on auto if everything is working ok. Depending on your memory if it has an XMP setting and it works fine just use it. If not you will have to get your hands dirty and set things manually. Just try riunning the system as you would normally use it and if there are no problems then fine.

You have anything to add about the Cpu Clock Drive and PCI Express Clock Drive? After the F8 update it turned them to 700mv each. i clearly remember that they were 800/900. Did this mean that the bios update returned to the fail safe settings? anyway i will try loading the optimal settings and see if it restores them.

Unless you loaded Optimised BIOS Default settings after the update it willl just revert to Fail-safe BIOS Default settings. I am not sure of the exact settings in there but I expect that is what the difference is.

There you have it, i didnt load optimised after the F8 update. I will check first thing when i go home. Thank you so much for your overall help Mantis.

You are very welcome and hopefully that will be an end to your problems but if not just post back again.

Hello Mantis,

Checking back after a while i wanted to say that everything is running very smooth and i decided to change that 
Quick question :
I got this i5 750 running on default values for a month now and i think it is time to OC it a bit.I decided to bump the BCLK to 150 because i dont want to mess with voltage control. That will give me an OC to 3.2 -> 3.6 with Turbo. The question is about the RAM.
I have a 2x2GB Kingston XMP 7-7-7-20 1333 @ 1.65v. Now i have XMP enabled and it has detected those values automatically.
If i bump the BCLK to 150 what steps must i do in order to configure the RAM? I assume i can't just leave it to XMP as it is.

You can just put in all the settings that you've just given me manually. You might find that it will work anyway but it is no biggy just to change them. The only thing you probably will find is that by adjusting one setting it will mean that you have to start making other alterations too to make it work and keep it stable including upping the voltages. This in turn means more heat to get rid of.

Theoritically speaking a change in the base clock from 133 to 150 doesnt require any voltage tweaking (i read that at Tom's). The question is about the RAM, if i do that i am afraid i have to set the timings,mhz and voltages manually.
