Overclocking Q9550 on EP45-UD3P

[Aphrodite]

I had updated my pc configuration. I bought a Gigabyte EP45-UD3P motherboard and an Intel Core 2 Q9550, 2GB Corsair DDR3 12800 and antec 500Watt power. Plus I am going to add NVIDIA 9600GT card, two hard drives and two drives. Knowing that this processor is clocked at 2.83 GHz of origin, do you think that up to 3.83 GHz is possible with a Zalman cooler Thank you to all who take the time to respond to a new in overclocking.

Your Q9550 should still be able to turn a 4 GHz H24, mine is stable at a PE ~ 4Ghz with 1.42v vcore of, OCCT 2.0 30 min. After cooling is another story, I was about 70 ° per core with a NHU12F. I plan to migrate elsewhere to this motherboard. If you have enough ventilation in your rig then you might not get much issue. A good PSU is also applicable in the same sense.

After a complete re installation of my system, I lowered my OC for the Q9550 but no longer has vcore 1.27v. Result the temp ° dropped drastically. 30 ° idle and 46 ~ 50 ° under 2.0 to 3.4 Ghz OCCT. I am a test of 15 min therefore not absolute, but it's reassuring, I urge on the tests this weekend to get close to 4 ghz with a vcore as <1.4 or even possible 1.37v. A 3.4 ghz at 1.27 vcore is the just limits, I got a message from pc probe on the cpu voltage and this after OCCT test and 3DMark06.

Does it is good to take a DDR3 system support for overclocking over DDR2. Otherwise the Q9450 3.8GHz clap in air cooling. The Q9550 with a coef of 8.5 should not be too hard to get there. I plan to have to same with a GPU support. The motherboard which I am using right now is capable for running my new processor but does there is a need of upgrade for overclocking support.

According to me the Q9550 processor are really not made for climbing up in fsb, I hardly had more than 460 fsb with Q9550 ES 1.35V vcore at 1.33v pcprobe which shows out warning. SuperPi crashes on the 32 MB 460 * 8.5, I shall publish this post on the basis of best I could do. I spended a lot time in this. Then temperature is acceptable at 39 ° to core 0 in idle and 55 ° Max Supported and plus the temperature of the core.

Hello, did you try with a Vcore of origin there pMC. Increase the Vcore to 1.28 for example will not damage the processor. I reach the 3.6 without increasing the Vcore too, that while its still reasonable (o / c app), even at temperatures, knowing that eventually I opted for a Noctua NHU12P. The frequency on 3.8GHz for a quad is not bad anyway. But is also true that the quads are ultra limited to fsb.
