Please help im baffled!

2.5x seems none too stable on my Gigabyte P35 when installing windows 7 (random BSOD during or just after booting) - runs fine for XP - I usually use 2.4x which isn't a problem. Not sure why as everything else is stable. Prolly just some random FSB hole or something.

If your having problems getting overclock settings to stick on a gigabyte board try disabling USB Legacy support.
 
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! :p


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! :cool:

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! :o

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! :eek:

Thanks for all your help, im going to go have a tinker with the bits you have given me.
One thing i picked up when reading the tutorials, was coretemp, at 3.ghz my comp is idling about 42degress.
Going to test the mem, stress it a little, but as long as the temp stays under 70 ill be happy!
 
Can you do 400x8 with the ram divider on 2 so your ram is 1:1 800Mhz as rated?
This is what I have had to do in my Gigabyte as my board wont let me run my ram over 800 even though it is rated to 1000.
I think Gigabyte is the problem

Believe it or not but the system seems to be coping extremly well, even so much i feel like iver just purchased a new comp!
The Dual core CPU is running 360*9 @ 3.24ghz
The memory divider seems to be holding steady at 2.5 meaning im getting 900 i think it is? (does this mean ive overclocked my memory 100hz?!)
Run intel burn and am getting 5out of 5 successfull runs.
Edit. The CPU does go unto 70degrees at max load but the cooler that i have (not fantasic, not stock) seems to get it down very quickly, i think this is ok?!?
Ive even just told my ATI card (4850 512mb) to overdrive and the GPU is working at 690mhz and mem on 1140mhz.
All in all a very nippy machine for very little alterations in 3 years.
Maybe in 12 months, to 18 months down the line ill look to starting afresh with i7 when it comes down a little?!

What do people generally do with their old rigs that they would considder average, but to the mere mortal, still quite powerfull worktops! Flea bay?!
