@amd125:
The Q6600 from the factory may be slightly inferior to the Q8300, but what's interesting about the 6600 is that it has a 266 Bus and a multiplier of 9. In this micro, if it comes out a little decent you put an FSB of 400 with a multiplier of 8 and you have it at 3200. I'm talking about the 6600 "Go" revision because the first "B3" revision were hotter and went up less.
The problem with the Q8300 is the "low" multiplier of 7.5 with a bus of 333. This makes that with a bunch of DDR 2 800 memory the Q6600 you put it at 3200 and the Q8300 only gives you an overclock of 3000.
And if you have better memory, or the micro comes out good, you can put the 6600 at 3400 (some have it at 3600 but with very good cooling and also with a very high voltage in general).
My 6600 micro has the worst VID that exists 1.325, that is, it needs a lot of voltage to go up, and even so I have it at 3200… ;D If it were good, it would go up more. That's the difference with the 775 platform and the Bus. In general, for two similar micros in frequency, for overclocking it's more interesting the one that has the highest multiplier and the lowest bus. In both things the 6600 surpasses the 8300.
That's right, both micros are very similar from stock, but to tell you well about the Q6600 it's enough to say that it's a micro that came out in early 2007... there's nothing, it's been 7 years, and to this day accompanied by a good graphics card it can still move most games, and at the office level, it still performs very well.
And to push it further, there are Xeon processors socket 771 that are compatible with 775 boards, depending on the chipset, and by fixing the pins on the micro and in the board's Bios, you admit these processors. I won't expand but these micros are selected to work in servers, so they are usually of higher quality than the normal 775, reaching some speeds of 4000... but I don't want to confuse you more than I would extend too much :wall: These micros on Ebay UK especially and USA are found at a low price, and I know more than one from other forums that for 40-50€ they have picked up a micro that they have put at 4000 with DDR3 memory and I can assure you that a Quadcore micro at 4000 even being old, performs like a champion.
To finish, I've tried to be clear in the explanation although brevity is not my thing. If you understood me well, otherwise, read some overclocking guide that will always be good the knowledge acquired.

Thanks, don't worry.. you can expand as much as you want! Well, I had no idea about the 771, I didn't know that. I'm going to read the guide you mentioned. Yes, mine doesn't go beyond 3.0 Ghz, and the ram is from 800 to 960, and if I put it at 1021 the q8300 stays at 2, 5 Ghz and doesn't go up from there… I get the impression that it moves slower if I increase the ram than if I increase the core. Besides, I think the ram breaks much easier than the core so I've left it at 20% and auto and it stays at 3.0 and 960 ram. I was trying to increase the core to 3.0 and the ram to 1020 (a little more than 960) but I'm not sure if it can be done, there are some voltages that the bios lets you touch but I have to read first.
Even so, it even seems to me that the pc moved faster with the E8400 increased to 3.6 Ghz than with the Q8300 increased to 3.0 Ghz both with the ram at 960. Could it be because the E has 6M and the Q only 4M cache?
The cache thing also has me confused, it's supposed to be a kind of buffer?
Thanks, I'm going to read the guide.
Best regards!
