hello, i just built a budget pc with e6300(new one with 2.8G,45nm), p31 gigabyte, 2gb 667, 4850
im trying to oc e6300 from 2.8 to at least 3.8, but im stuck at 3.5. i cant make it post with fsb higher than 340.
it does post at 340 fsb, with 1.35V core
ram fsb ratio is 2.0 so its runnging at 680mhz (stock 667)
i didnt change ram timings
i tried up to 1.55 vocore, raising northbridge voltage, fsb voltage, ddr2 voltage, it doesnt post when i put over 340fsb
Your motherboard isn't stable enough to give you higher overclocks. If you can borrow a friend's P45 chipset mobo, you'll see that your 6300 might go a little higher. Could also be a heat issue. Are you using an aftermarket CPU cooler?
I found if you have to fight hard for FSB speeds, it's better to replace the board rather than fight it with high voltages. I picked up a new mainstream GB P45 board, it does 533 FSB quite happily with only a small bump in NB voltage.
I wouldn't expect the G31 to be much of an overclocker, owners above seem to agree with that as well.
But if you want to try one more thing.... it could be your RAM, it's rated 667 and you're running it at 680+, try raising the memory timings. If it's 4-4-4-12, try 5-5-5-15.
gigabyte's p31 are good overclockers, basically a p35 with less ram slots
G31 mobos are good for basic overclocking but not beyond. I have both a G31 and a P45 chipset mobo and the G31 can't get near 4 GHz (8 multi X 500 fsb) that the p45 easily reaches and remains stable too.
oh wow, people are telling me about g31 chip, but IT IS NOT!! (if it is not same as g31(
it is P31,
i have both g31 and p31 boards from gigabyte. i dont know the performance difference but they have different OC option in the bios.
