Ok that sounds good, I presume you mean the memory is running
333MHz/DDR2-732
In theory and assuming all other things are equal you should be able to go from 3.3GHz(9x366) to 3.6GHz (9x400) without overclocking your memory (as it's synced with the FSB 1:1). You may find other obstacles block your trot up to 3.6GHz . . . maybe your CPU can't run that frequency or that FSB or perhaps your Northbridge will need more voltage, deffo worth a try though although I think it will be better if you first do some *isolated* memory testing by setting your CPU back to 3.0GHz (9x333) and using a memory divider to set your memory running faster . . . 333MHz-FSB while the Memory is running at 400MHz/DDR2-800
Assuming you have no problem working out how to change the DDR2 speed you can then test your sticks at the faster speed, once they pass you can just slowly raise the FSB which in turn will begin to overclock your RAM. 400MHz/DDR-800 should be all good but if you can run them faster it may prove useful, more on this later . . .
Give it a right proper testing (switch off, power unplugged etc etc) before we breath a sigh of relief!
I'm not 100% whats going on with your machine just yet but I am feeling your original problem was caused by either a Memory problem (running too fast!) or perhaps a Northbridge problem.
If you keep overclocking and posting your results in this thread things should become a lot clearly!
Good thinking batman (I missed that in my previous suggestions).
However if I may suggest that at this early stage of your testing it will make things a lot easier if you don't change the CPU's default x9 multiplier as that will introduce another set of variables which may or may not hamper your basic clocking or confuse you!
The stage to drop the CPU multi isn't quite here yet, first get some *isolated* memory overclocking done (as mentioned above), once you know how fast your RAM can run you can put the sticks back to 1:1 sync and begin doing some *isolated* CPu overclocking . . . . and once that is done your ready to start tinkering with the Northbridge and adjusting the CPU's multiplier downwards!
Plenty for you to do, make sure you give enough stability testing time to each bit, patience is a good virtue here as a lot of folk seem to really rush their testing and end up in a confused heap when it all goes wrong!
Can you also download
MemSet v:4.0 please and include it in any future screenshots you do. DOn't worry if you don't understand how it works at first but it displays a lot of useful information (which may change as you tinker!).
Also download
IntelBurnTest v1.9 as thats a great tool for testing and heats up your overclocked system a treat!
