my current system:
processor
intel core 2 duo e6750 2.66 right now OC'd to 3400MHZ (425X8)
MOBO
GIGABYTE GA-P35C-DS3
RAM
CORSAIR 2X1GB 1066MHZ
CORSAIR 2X1GB 800MHZ
(TOTAL 4 GB)
CPU FAN
OCZ VENDETTA 2
my question is...
If I buy an E8400 processor, which stable speeds should I be able to reach with it?
And what will limit me? My mobo? Ram? I know for sure my slow ram (800MHZ) will limit me, but if I remove it, will my mobo still limit me? (Remember, right now I'm at 425X8).
THANKS!!!
 
So I OC'd my E8400
450X9, 1.3500 VCore.

I ran OCCT but after 5 minutes it crashed because it reached the max cpu temp (which I changed from a default of 80 celcius - to 72).
I changed it to 72 because I saw on the intel website that the thermal specification is 72.4 celcius for this cpu.

Is this really the highest temp recommended? Or could I set the max temp a bit higher??
Thanks!
 
now I watched a streaming movie from a website on fullscreen and after about 40 minutes the picture froze and I had to shut down.
I changed the OC settings to 445X9, 1.325 VCore.
right after boot, I started HWMonitor, and a few seconds later I saw the max temp of core#0 spiked up to 64 celcius (core#1 max temp is still at 58 degrees only)!
Is this ok? I don't understand, even after lowering the vcore why does this happen?
 
your gonna mess up your motherboard the maxium system bus your board handles is 1333mhz you've got is set a 1800mhz!!! you've got big stability issues. If you wanna save yourself some cash i suggest you drop your system bus down to 1333mhz. I know 1333mhz is stock but you can always adjust your multiplier. Keep your vcore set at 1.35v after all the pwm will monitor that voltage and adjust the frequency to what is needed. run prime95 for atleast 2hrs to check for stability issues. If your not happy with your results you will have to invest in a better motherboard. If you carry on the way your going your gonna end up damaging your motherboard and also risk damaging your cpu due to overheating.
 
450x4 = 1800mhz always multiply your system bus frequency (fsb) by 4.
cpu frequency 450x9= 4050mhz that's mega high. atleast you know your chip can reach that frequency.

the maximum system bus frequency your motherboard handles is 333x4=1333mhz. so your pushing your system bus frequency to high more that the board supports, so therefor will cause damage to your motherboard.
 
how do I know the max system bus my board can handle?
and why multiply by 4? is that because I have 4 sticks of ram? If I had only 2 sticks would I had to multiply by 2?
Thanks!
