Hi People.

Santa has a surprise waiting for me at christmas - in form of a Intel Core2Quad Q9550.

My current system is in my sig, and my current cpu is a good oc'er (have had it running 3,9Ghz - but the chipset on my old motherboard wouldn't run stable and became too hot).

Now my questions are: What are your oc results on the Q9550?

1. what stepping did it have?
2. max oc on stock voltage?
3. max oc with upping the v-core?

I know a lot of you are probably thinking: "why go for an outdated 775 platform, with i5, i7 etc. prices falling?" - well I'm a student, and therefore can't afford a total system replacement. I have pretty ok hardware atm, and upgrading with a new mobo, DDR3 etc. would just cost too much.

How high will I eventually have to push the Mhz on the Q9550 to outperform my current E6750 running 3,5Ghz in singlethreaded applications?

Thanks in advance

Because the architecture of the Q9550 is about 5% - 10% more efficient depending on what you are doing, I'd say around 3.3 GHz.

I have a C3 Q9550 running at 3.6 GHz at 1.3625 volts with a TRUE in an Antec 900 case, 24 hour P95 stable. Load temps are 58 - 61 C.

I have the Q9650 (the difference with Q9550 is in the multiplier - extra 0.5) and I was able to push it to 4.23 GHz on P45 (GA-EP45-UD3P) (9x470). The voltage is the max specified by Intel - 1.36V.
On stock voltage (1.26) I went up to 3.8-3.9...

@4.23 my temps are arround 56-57 with IFX-14 with 2 akasa apache fans.

but I don't know how much FSB you can expect from your motherboard, but the processor itself is quite good

Especially the E0 chips.

Sounds great - I think I'll let it run at around 3,5Ghz and then pust it further when I need more power eventually. :p

yes, I forgot to mention the stepping... sorry about that.

I got lucky and got 3.7ghz with 1 bump (1.25) over my VID with E0 stepping. Unluckily, my mobo won't let me go much further than about 3.9 @ 1.35 into windows (some people get as high as 490 on my mobo :[ ) and only 3.8 stable 1.325, I know this CPU has more room. Stays around 49-52c on load with a Zalman CNPS9700 110mm when its on 3.7ghz. 55-60c on 3.9ghz.

Oh yeah, and on stock voltage I got 3.6ghz.
