hi everybody, this is my first post here.
I apologize for my bad english.
p.s > im a nub in overclocking
Core 2 Quad 6600
Motherboard: Gigabyte P35 (something...)
GPU: Zotac geForce 9800 GT
Fan#1 CPU: Zalman 9700 Led
Fan#2 (back case): 12mm Backfan.
Ram: 1GB x 4 (667hz)
i currently overclocked it to 3.0 and my temperature in 100% usage is around:
45c (core / cpus x 4) (if i remember correcly - im writing this not from home ..) - temperatures with everest.
should i mesure it with something else
i really whanna push my cpu further.
how far do you think i can push it with those specs..?
can you post what setting should i use for the option you present
as in (fsb / volt / etc..).
should i put extra cooling? or i shouldn't push my cpu that far..
how far can you push a q6600 with air cooling... (no wierd stuff - aka nitro cooling / water / etc...)
Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the System Memory Multiplier from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 266 MHz, your memory clock should be at 533 MHz.
Download CPU-Z to check your FSB:RAM ratio. It should be a 1:1 ratio.
You may be able to push a little farther by tinkering with the memory settings. Set the RAM voltage to 2.2 volts and relax the memory timings from 4-4-4-12 to 5-5-5-15 or 5's-15 to 6's-18. That should let you push your memory a little farther.
The odds of hitting 3.8 GHz with stability are very small. Prime95 is popular for stress testing.
If this is a working system, stability will be more important than if it were a hobby system.
Hey, I also have a question related to OC Q6600. I got mine runing 3200 mhz stable on 1.375 V. I cant get much more, even if i increase voltage. I've been told i should do slight voltage increase of other components. For example i can manipulate ICH voltage in bios, but im worried changing values could damage my SSD drive? What you think?
Lunarii, you didn't provide nearly enough info for us to even guess what the problem is. It might not even be a voltage problem, read below.
Syp34892, buying faster ram isn't going to guarantee you a higher overclock. Lets say you wanted to hit 3.6GHz. Thats a 400MHz FSB x 9 CPU multiplier. You said you had 667MHz ram. 400 x 2 = 800 which is higher then the 667MHz you have. In this case not only are you OCing your CPU but your ram as well. By reducing the parts your OCing the greater your odds of success. (Lunarii, this is why I said it might not even be a voltage problem.)
You only need to buy 1066 if your planing on pushing your FSB up to 533. 400-450MHz is fine for most people. You'll also have better luck hitting 3.6+ if you have a G0 stepping CPU.
