New CPU and BIOS update required dilema

[Messerschmitt]

Hi, I just returned my E6600 1066FSB and got E6750 1333FSB, but on my mobo Gigabyte P35 DS3R website it says that for E6750 support you need BIOS F4, but I only have F3. The requirement for E6600 was only F3 as well. Before I open my packaged E6750 please tell me that once I install my new E6750 I can go into BIOS and use Q-Flash to update it.

It should work, only the CPU will get a bit more voltage and would be seen as unknown CPU.

80% That it will work with most motherboards.

I think some one could confirm this...

Unless the BIOS adds new support for previously unsupported FSBs or a specialized instructions, most of the time you can boot with your unrecognized CPU and update your BIOS. To prevent damage to your CPU, it's important to find out what the correct vCore voltage is for your new CPU and manually set the vCore to the correct value until you upgrade your BIOS. The same also applies to the FSB and any other settings which can be configured manually.

So, if posible you could indeed set the BIOS to 1.050-1.100volt, that´s the CPU´s "normal" voltage...

Ok, I did an update to BIOS, even tho before the update on the POST screen it detected it as being E6750 @ 2.66.

Anyway, any reason why would the temperature now be kept at around 37c when with my E6600 was about 33c? Also on this CPU the CPU fan starts spinning immidiatly after turning it on, on the E6600 it was taking about 5 minutes until it was starting to spin.

Is it because this one runs at higher frequency and also has 1333FSB instead of 1066?

Both had stock coolers.

The higher clock speeds are what's going to give you those slightly higher temperatures. 37C is nothing to be worried about though.

If you're worried about the noise, you should enable some fan management that your motherboard should have in the BIOS. Either that or grab yourself a fan controller like the Zalman FanMate2 and slow down the CPU fan speed a bit to lower the noise.
