Hi folks,
i oc my gigabyte g41 and DC E6600 3.06 like this..
I set fsb to 333 and removed 0.5(rounding)...ram: 1x2GB hynix 1333 ddr3 at 7-9-9-24@666mhz

cpuid shows 3.66ghz each core...and hyperpi results showed huge time saves...

No volt change and at stock fan...no cab fan and room temp is ~30c....
Shows Idle temp 32c, at full load 55c....avg 42c

i use it for net browsing that too text only...

it won't boot at 350fsb...ram can do 9-9-9-28 at 785mhz... So it must be cpu...

My questions..
1) do increasing cpu volt solves the prob or not
(mobo allowing fsb range: 100 - 1200)

2) cpu fails at 60c...is this the limit or due to mobo(warning temp is 60c)

thanks...
Sam

No. The E6600 Wolfdales can frequently be pushed past 4 GHz. Your limitation is the G41 motherboard. The G41 chipset is an economy chipset with a limited FSB freq - somewhere around 340 - 360 MHz depending on the motherboard. One of my G41's has a 352 MHz limit. 352 MHz works with full stability. At 353 MHz, the board does not even POST.

1. Up to a point, increasing CPU voltage will help. But the real limit is your G41 motherboard. And it doesn't matter what the motherboard BIOS range is. It depends on the chipset.

2. You are seeing a coincidence. Your CPU temps are 60 C when other limiting factors kick in. A Core2 CPU will run happily for days at 60 C.

I set the warning to 70 C. Intel's recommended max temp is about 72 C. "Average" temps do not matter. Load temps are what is important.

update: i have set mobo warning temp at 70c and now my cpu works over 60c too.....
next time i will definitely consult here [read >50 other websites but something going wrong every time i buy a pc]

this site has every info..... thanks to everyone here......
