oc'ing e7300 on dg35ec

Intel / E7300
January 6, 2010 at 04:26:54
Specs: Windows XP
my specs are:

intel e7300(c2d, 2.6ghz stock)
mobo- intel dg35ec
ram- transcend 800mhz

my core voltage is .920v using cpu-z.
i learned about the bsel mod to oc the intel processord on oem\intel boards.
so i wanted to ask how much frequency my mobo can support using bsel mod?
also should i increase the core voltages(as most other people have it in the range of 1.2-1.4v)?
could you give me a link giving details about the bsel mod specifically for e7300?
thanks in advance.

According to Intel, the voltage range is 0.85V – 1.3625V:


If your CPU is running at 0.92v, you probably have SpeedStep enabled. Was your CPU running at full clock speed (2.66GHz) when you checked CPUZ?

when my processor was at full stock speed(2.66ghz) the core voltage was .928v.
when my cpu is idle the clock reduces to 1592 mhz(266x6)

To be sure, temporarily disable SpeedStep so that the CPU runs at full clock speed at all times, then check the voltage. Intel doesn't give a default voltage, just a range. Most sites report the default at approx 1.2V.

disabled speedstep in the bios but cpu-z still showed clock as 1593mhz at idle and 2660mhz at load.

Try to compress big file using win rar or 7z or try to converte audio(that will force cpu to run a max or stock speed) or video and open cpu z check again the vcore voltage.

did the same.
the voltage is .928 at max load and at 2.66ghz.

i tried the bsel mod by putting some nail polish on the bsel2
it did not work. cpuz stiil showed frequency as 2.66ghz.
here is the link to the mod i used
i did the 266->333 mhz. but instead of using the circuit maker pen to join bsel2 and vcc, i insulated the bsel2 pin, hoping it would work.
it didnt.

edit: covered the bsel2 pin with a tape and it worked!!
cpu-z shows 1988mhz at idle and 3333mhz at full load.
still the core voltage is .928 volts. and even after disabling the speedstep, the processor does not run 3333mhz at all times.
