Hey All,

Before I start here is my rig spec:

Intel C2D E4300 @ 3ghz (334 x 9)
Gigabyte 965P-DS3 Rev 3.3 F12 Bios
OCZ PC6400 Platinum Rev .2 2x1gb
BFG 8800GTS OC 320mb
Hiper 580w Modular

Now my problem is it appears the fsb is hitting a limit when trying to overclock, it wont go any higher than 340fsb no matter what I try. I have lowered the multi on my cpu to make sure it wasnt that limiting me and I got the same problem. So then I thought it could be the OCZ memory which is running on a 2.0 divider so its not even running at its full speed so it cant be that. This FSB limit is stopping me from clocking my E4300 any higher than 3ghz which i am happy with but I want more.

Anyone got any ideas of what could be wrong or could it just be the case of a bad overclocking motherboard.

Thanks, Sam
 
May not even be the board tbh. Its widely noted that CPU's can have FSB walls, do you have another board, or access to a mate with another board who can see if your CPU can POST at higher than 340FSB?

340FSB is low for a CPU FSB Wall though. What voltage do you have through the chipset?
 
I followed the guide and set it to + .01 and tried the max of + 0.3 when it kept failing but still no joy :confused:
 
It's more likely not enough cpu voltage also set the fsb voltage to +0.1
i would try
cpu voltage 1.40
mch +0.1
ram +0.1 dependant on your ram voltage requirements +0.1 is 1.9 volts +0.2 is 2 etc
pci express 100mhz
keep upping the cpu voltage til it works dont go over 1.50 volts to be safe though.
Try 9x 343 should boot on stock cpu voltage and just ram on default and
chipset on default though.
Had ds3 3.3 with 4300 but geil value ram 1.8 volts
343x9 always worked for me even on stock volts for everything it would boot.

It cant be the CPU though because even if I lower the multi to like 6x so its running really slow it still fails.

I have tried the following voltages:

FSB + 0.1
Memory + 0.3
CPU 1.45
 
yes but have you tried say 9x343 or 9x 344-355 and so on
it's not the board could simply be the cpu with a limit or doesn't
like certain numbers.

i think it's another issue as i have same board and had 4300
it would run fine 343x9 all voltages at stock apart from ram at +0.1
currently on my 6420 @3.2 all voltages @ stock
