gigabyte lga775 auto-overclocking

[cubby1223]

Went in to a business today, knew the machine I was working on had a Cedar Mill Pentium 4, and I had a spare Core2Duo E6300 on hand, swapped it in. Gigabyte motherboard, GA-G41M-ES2L, and the board auto overclocks the cpu!

The cpu is rated at 1.86ghz, but is running at 2.8ghz. This machine is not doing anything cpu intensive, I'd prefer it not overclock, keep the cooling down and better chance at greater stability, but cannot find any way to turn it off in the bios. I saw where to set the multiplier and the bios startup screen now reads a Pentium Dual Core 1066fsb & 1.86GHz (there is no "auto" setting around the multiplier settings in the bios), though Windows still recognizes it at 2.8ghz, both on the identification and also the detected speed in the system properties screen.

Is there a way to stop the overclock? I have the latest F9 bios.

Tried dropping the Host Clock (FSB) speed too?

I ran that motherboard up untill nearly 2yrs ago, so my memory is vague.
But I do remember the bios being pretty good allowing full controll over such things.
Just poke around the bios and set everything to defaults or safe values.

Core 2 Duo e6300 = 1.86GHz (7x266)
Pentium Dual Core e6300 = 2.80GHz (10.5x266)

my guess is you have the Pentium Dual Core version, and it's running at the stock settings!?

to work at 2800 the C2D e6300 would need the fsb overclocked to 400Mhz, and PCIE to around 115 on G41, I don't think auto OC on a lower cost board would do that!?

and if you have the pentium version, don't be disappointed, it's MUCH faster than the C2D.

You're probably right on that one!

I bought this cpu off of ebay a couple months ago http://www.ebay.com/itm/281091765516 listed as the core 2 duo version along with image, and I cannot say that I ever checked the cpu speed printed on the heatsink.

I suppose I'll still be disappointed in that I gave away this cpu for free!


I've had stranger things with low-cost motherboards, once bought the cheapest board on Newegg at the time to put a system together with a Sempron 145, power it on and by default it said I had an Athlon II 240! I didn't complain!




Thanks
