This is the belarc advisor system thing that you requested gandalf thank you for your help so far

While I working on this grayout problem, you might want to download/install this...CPUID.

The Belarc showed your missing some Security updates. You might also want to fix that.

CPU-z showed my main board as the asus P5LD2 VM the asus update tool calls it P5LD2 VM conroe and for that reason the regular asus drivers wont flash my mobo through the asus desktop tool but every other program i have used both of the two you said included just reported it as the P5LD2 VM
i hope this is of assistance

many thanks

What is the E number of your CPU? E6600.

Never mind...

From: Intel Core 2 Duo Overclocking guide!

The first step is to enter your BIOS. To do this, boot up your computer and while it begins to post hit the Delete key.

There are two main ways people go about overclocking. The first way is by increasing your FSB by 10mhz at a time and running Orthos and monitory temps, and increasing voltage when needed.

The second way is to just jump into a moderate overclock. This is my favorite way, especially with the Core 2 Duo line and all of its potential. When I overclocked my e4300, I immediately overclocked from 2.4Ghz from the stock 1.8Ghz. I did this by upping my FSB to 266. I then ran Orthos and continued to overclock the FSB 10-20Mhz at a time until I hit a problem. Once I got an error or could not post, I’d add some vcore to the CPU. Then would boot up and run Orthos again.

When trying to figure out your CPU’s max overclock, set your memory to a 1:1 ratio. That way you are not putting unnecessary stress on your RAM. Once you figure on your CPU’s max overclock then play around with the memory/cpu ratio and tighten up your timings if needed.

What kind of overclock can I expect for my Core 2 Duo?

On high end air cooling, and the right RAM and a good overclocking motherboard, you should expect something around the following:

E4300 – 2.8-3.2Ghz
E6300 – 2.8-3.4Ghz
E6400 – 3-3.6Ghz
E6600 – 3.2-3.8Ghz
E6700 – 3.3-3.8Ghz
X6800 – 3.4-3.9Ghz

thank you very much for your responses gandalf but this does not exactly help my problem as my bios is greyed out i cannot actually access the overclocking menu to carry out the steps you detailed

thanks
wilf

p.s happy birthday

A little more info if it helps is that printed on the motherboard is this information presumably a model number but it is slightly different than what the programs are telling me:

P5LD2 - VM/S

thanks again
wilf

Can you increase the FSB?

According to Clocks are Greyed Out on 680i SE that might be a requirement for overclocking.
