_₌= The Q9550 Club =₌_ [Please read first post] - Page 227

He has fans dialed down to almost zero, that's why he's getting those temperatures.

As to IBT... I like to get it so IBT maxes out just below my temp threshhold (so 72C is my cap on LGA775 45nm, so I get IBT to max at 71C). That way, I know no matter what I'm using on my computer, the temperatures will NEVER go above where I don't want them. Why put 8 foot ceilings in your house if you're family is all shorter than 6 foot? well, just in case.

Ahh. I guess my next question is, why only 3.4?

3.4 lets me run my RAM at the speed it was intended for, DDR3-1600 9-9-9-24 1.80V. Above that I'd need to drop the RAM speed lower. The voltage I need on my C1 goes up quickly after 3.4 so I'd need to make my fans a lot louder to compensate, which I'm trying to avoid. I don't think 66C is too high under full load. I'm down to 1.168V cpu-z and I'm going to do something similar to what daclownie said - increase the fan speed just enough to keep IBT maximum in the low 70s. While IBT generates an "unrealistic" amount of heat I like to know the hottest my chip's going to get.

Ah, poor Q9550 is so dry now... Just took the WC rig apart, moved this EP45/Q9550 over to a new tower to pass over to my brother in about 10 days once my Ivy rig is assembled and ready to rock... Just working on an overclock for him now...

With my Arctic Cooling Freezer 7 Pro, some MX-3 TIM, running at stock volts, have it up to 3.6GHz, temps 53C... Up to 2 1/2 hours now in Large FFTs on Prime95... Love this chip. Gonna miss her :/

Intel Core 2 Quad Q9550 E0 - Ser. L836B247
Asus Striker II Formula BIOS 2102
4GB Corsair Dominator 1066MHz XMS2 - CM2X2048-8500C5D
EVGA GTX470 SuperClocked
Corsair Pro Series HX750
Antec Kuhler H2O 920
Intel 80GB Gen2 SSD

Currently @ stock = 1333FSB & 1066.7MHz RAM @ 5-5-5-15-2T
All voltages stock/AUTO



Having problems with crashing. Everything @ stock settings. Idles at 32*C, full load at no more than 55*C. Obviously @ stock settings the computer is absolutely rock solid.
The problems arise when I restart the computer. I hear a strange clicking sound - around two or three clicks - then POST completes and after the HDDs are found lots of white lines appear on the screen, sometimes multiplying and sometimes just sticking still. I have to unplug the power cord from the rear of the base unit, wait a few seconds and then power back on, and everything is fine.

GPU has never gone above 92-95*C, and has never crashed in-game.

I have recently placed a 120mm fan over the NB and SB heatsinks which has greatly reduced the temps of NB and SB, and also the GPU, but has not stopped the restart crashes.

As a side note: I have lost all confidence in overclocking my setup, as when I actually looked further into the stability of my clocks everything crashes. Even increasing the FSB slightly requires 1.31V vCore, and it still crashes under OCCT and Prime95. Very ****in' annoying!!! So i reduced everything back to stock and enjoy idling at 30-32*C 1.1750V vCore.

You might want to set a few voltages manually like for the Ram and such. The Striker II was a pain in the ass to overclock but it did overclock well with good cooling. That crashing issue you seem to be having does sound a bit odd and sounds like it could be something to do with the GPU's or the PSU. Have you figured out where the clicking sound is coming from because outside of a normal HDD spin up click (Seagates can be loud) it should't do it repeatedly.

need to update my overclock...

I'm looking for someone that's bored enough to help me get started...

The system I've put into "Rigbuilder" is getting pieced together this weekend. I am absolutely new to overclocking, but I build my own systems and I'm comfortable working in the BIOS. So where, exactly, do I start? I mean, is there a certain order that values are changed? Do I work on overclocking component by component or do I just go in and start changing values across the board based on numbers that I've found posted by others overclocking similar machines? I'm determined to do this and any help getting me there will be greatly appreciated. I'll post my progress as I go if someone here can help. It's hard to be sure if this was the best forum for me to post in... but it IS a Q9550 and who better to ask? Thanks in advance for any assistance.

I highly suggest reading some of the overclocking guides that are stickied. They are a wealth of information that will point you in the right direction. Before you begin, you want to make sure that you have adequate CPU cooling, and that you have the proper utilities and programs required for overclocking validation.

Its really just trial and error, and it will take a great deal of time to lock down a max overclock. A pen and piece of paper is your friend, as you can keep track of which voltages are needed for what clocks.

Make sure to set your PCI-E frequency to 100mhz. This will lock the bus speed at this frequency and prevent it from increasing with the FSB setting as you overclock. Other people suggest disabling any power saving features, such as EIST. Its really up to you. I personally like having my CPU down clock at idle to save some power.

Pretty much your going to increase your FSB in 5-10mhz increments until your system fails to boot into windows or you get a bsod. Try to keep your ram frequency within its rated value, underclocked is ok, this way you will not be throwing another variable into the equation.

Personally, I prefer to dial in all my voltages rather than leave them on auto. I have found that the bios can over-volt the board components if left on auto, especially while overclocking. I recommend dialing in a manual setting for Vcore, memory timings, memory voltage, FSB term voltage, CPU PLL voltage, and NB voltage. Post a screenshot of your bios so that some of the folks in this thread can better help you .

Thanks for sharing the wisdom! I'll be starting later today and will definately be back to continue the process.
