Help needed on overclocking Core2Duo E6300

Greetings, i started this thread to try and find some help regarding the overclocking behavior of my Intel C2D E6300. This is my platform:

Mainboard: MSI P43 Neo-F
RAM: 2x2GB 800mhz A-Data gaming (the black ones)
CPU cooler: Zerotherm FZ120
mainly, and the other components
GPU: Forsa 8800GT
HDD: Western Digital 6400AAKS
Case: Antec 300 + CM red led vents

At the moment, my E6300 is overclocked from 1,86 to 2,73 ghz, at FSB 390 (processor has 7x multiplier) and the RAMs are underclocked to 780 mhz. If i set one FSB point more, it doesn't boot.
This is the screenshot of my BIOS oc screen:

Please tell me what to do :(.
Thank you
 
bump your vcore/nb/sb voltage, then raise your clock frequency in small 5-10mhz incriments!
 
I have no idea, never overclocked a C2D before - what incriments does your voltage go up in? .25V?
 
I don't understand what is MCH and VTT FSB ...
The VTT FSB incriments are 0.1v and on MCH about 0.25v.

I have a e6300 that goes up to 440 mhz. It needs more cpu voltage and sometimes more vtt fsb depending on the board.
 
Change cpu voltage to 1.45. Change fsb/dram ratio to 1:1. See how high you can get it. Fool around with vtt fsb or w/e. You can also set pci-e to 100 which helps.
 
I tried but still nothing :( it just doesn`t want to boot...

I made some comparisons between E6300 @ stock freq and E6300 @ 2,77ghz (how much i managed to go)

3dMark 2006
E6300 - 1,86ghz - 8168 points
E6300 - 2,77ghz - 10597 points

Better than 2000 points difference. Interesting :)

Did you also adjust the northbridge voltage along with the CPU vcore?
 
Interesting... I'm in the exact same situation, above FSB390, nothing goes.
 
arent some cpus limited?
 
Tigger got his 6300 WAY higher than we did. Above 4GHz

thats an 80% overclock, but if you set your MHZ up by just 1 and it dies, then the problem is definately not voltages or ram dividers.
 
My B2 stepping gets up near 500MHz FSB, but I'm thinking it's all just running a bit hot when it starts hitting above 70c with a crappy cooler. Still, good for heating my room :)
I have to use 1.45V CPU, 2.2V RAM, can't remember the exact voltage for NB and SB though, I think it's at +0.05V for each. Not a huge bump, but seems to be enough.
Basically, you do need to bump the voltage up a bit for it to get anywhere.
Then again, it's all dependant upon your exact CPU, and setup, so for you, the voltage might need to be lower, maybe higher.

65 nm need good cooling. CPU temp ?

I have a Zerotherm FZ120 cooler, in idle i have ~30 degrees and full load ~50. The thing is that with lower frequencies, the temperature`s the same.

Maybe the processor is limited, i have my E6300 for about 3 years and the old revision doesn`t support that much OC. Anyway, differences can be feeled from stock frequency to 2,77ghz.
 
I know what is the problem. The problem is with MSI and P45 and P43 above some point in yours about 400 FSB the memory divider it is not working it automaticly is set to max so you memory goes bout 1600 or some thing and there is no bios no nothing to help you. Sorry. For Pentium D 310FSB is the limit and the divider stops working and sets it self to max ratio if I put C2D 400 is the limit.
Here is my thread BETA BIOSES DON`T help either http://forums.techpowerup.com/showthread.php?t=75050
 
The memory doesn`t jump to 1600, at 400fsb the memory is at its stock frequency(800mhz).
 
And can send you user and pass from MSI ftp server where you can get bioses that are not yet put on their site.
 
The memory doesn`t jump to 1600, at 400fsb the memory is at its stock frequency(800mhz).

Wrong. After couple missed post the mobo will boot and it will offer you a to enter in bios without errasing you settings and you can see in bios that there are two ram frequencies one current ddr frequency in you case 1600 and other adjusted ddr frequency the desired one.
I`m telling you you can try raising all the voltages and lower you CPU multi and you wont post so in the end you will conclude that the CPU is not the limit the memory is not the limit.
Believe me I was :banghead: all week. THE MEMORY DIVIDER IS THE PROBLEM
 
And other thing for the P45 neo3 f that I had MSI has 15 bios versions. And for the current board P7N platinum it has 4 and P7N is year older than P45 that should tell you something.
 
And this is from MSI customer service:
This what I wrote
i use E5200 and when I lower the multi and rise the FSB when FSB is set above 310 memory divider in bios is not working always is set to 1:2 no matter what you set in bios
And the answer:
Dear Nikola,

Thank you for contacting MSI Technical Support.

Please update your bios to the latest version 1.61 to check,but we do not recommend you overclock for the whole system's stability.Overclocking may cause the system unstable.

1.First of all, please make a booting floppy.
2.Next go to our website to download BIOS file, then copy “AFUD4234.exe” and “A7514IMS.161” into floppy.
3.After that, please go to “BIOS setup” and choose floppy booting under “boot sequence”.
4.Under DOS mode, please type “AFUD4234 A7514IMS.161” and it will be updated successful!!

Warning:
1. During updating, please stop all working process to avoid update interruption.
2. Please must not cut the power or restart your computer during you flash BIOS!
3. Please also remember to Load Optimized Defaults under bios setup after you finish the BIOS update!
