overclocking q6600 help please

You have to increase your FSB, there is no multiplier overclocking on a Q6600

You increase the frequency from 333Mhz, to a higher value, however when doing this your RAM speed will also increase so you will need to adjust your divider for the RAM frequency, in order to keep in stable. It is not as easy as multiplier overclocking and requires some trial and error. There are plenty of guides available for overclocking a Q6600 or any Core 2 CPU.

All of this should be done in the BIOS.

System will crash, or not boot.

Forgot the Q6600 has a bus speed of 266 not 333.

I was also wondering, i got my q6600 to 2.71, but what for further, i need to get the core voltage higher or what ? Total noob got it to 2.71 from a help of friend upping the fsb to 301 only, also the multiplier dropped the next day, so i got it back to 9.

okay for your G0 Q6600 you should check in CPU-Z and confirm your VID. This is the min voltage that your working from. For example mine is 1.3 (which isn't a great starting point). For a G0 version you might get away without any voltage increase, but if it's unstable increase it in single increments, and run Prime95 to test for stability. Also you may need to increase your NB voltage an increment or two aswell. Overlocking is trial and error, so take it slow and read as much as you can about your CPU/Mobo combo. As snipergod has said there are loads of guides to overclocking a Q6600.
These are just some settings on my mobo which you can try:

CPU voltage 1.3
Ram Voltage 2/2.1
NB 1.53
SB: Leave alone for now.

Set ram fsb to 333 mhz. This gets the CPU to 3ghz (333 x 9, with 9 being the CPU multiplier)

See how you get on. With a stock cooler you will want to watch your temps very closely. Id recommend getting an aftermarket cooler, because the temps are an important factor. Without an overclock your temps at idle should be in the low 30's range, and at full load, low to mid 40's. When overclocking they will go a little higher. The q6600 can go to high 50's low 60's (degrees Celsius) and still operate well, but you don't want to be going over that really, or at least that's the objective.

Note: the settings I gave above are just guidelines, each mobo/CPU are different, and you may have to change one or more settings up or down slightly to get the PC to post.

Again, I will say, read read, and read some more. THe more you read about your CPU/Mobo combo the more you success you will have. Stay away from those simple overclocking options some mobo's have, as they often over volt.

Also if you have the option to link/unlink your ram from CPU this is good. Try unlinked option first, and set the FSB to 333. You can PM me, and let me know how you get on.

@ voyboyfan, with the stock cooler your prob not gonna be able to push it much more than you have.

Use the following for helping manage the overclock

Coretemp - To watch the temps of the cores as you overclock, keeping in mind the temps I gave further up
Prime95 - to test for stability, using small FFT's to test CPU and cache only. Normally for real stability you run Prime for a few hours. If you get errors immediately you know it's not stable. WHen you have no errors your obviously much closer to a stable overclock, and it's just a matter of tweaking.

this is a really good guide, with lots of info about your CPU. Mind you it's not the same mobo, but will give you a good idea as to what you want to change.

Have fun

edit: in addition to using Coretemp and Prime95 for testing. It's a good idea to get memtest, and stick it on to a USB stick. Your mobo should be able to boot from a USB stick. Memtest will test you ram outside of the windows envirnomnet to ensure the Ram is running well. You should do at least 5 passes to make sure ram is running correctly. faulty/damaged ram is one of the biggest reasons why overlocks won't post.

Also make sure to set your ram timings manually. most DDR 2 ram will run at 5-5-5-15-2t or something like that. You can tweak ram to run slightly faster timings wise, and I have mine down to 4-4-4-12-1t. The ram timings will be printed on the side of the module. Setting timings manually is important so the ram runs optimally, and won't fail the memtest testing.

edit 2: just saw your mobo is DDR3 ram. So although it will be slightly different, most of what iv'e said relating to setting timings manually will still stand.

The only limitations running DDR3 memory is the BIOS options available to you that ASRock has provided with this motherboard I see it lists supporting 1600mhz so what are you actually running in it?

In my 775 days I was running a Q9550 and overclocked it to 4ghz on air cooling, using an ASUS Striker II Extreme and 2000mhz memory, increasing the FSB could be stabilized because the DDR3 memory could support the speed increase.

But it was not an easy overclock to reach 4ghz, it took me back to overclocking 101!

It is a voltage balancing act with VTT, PLL, and GTL, I'm not familiar with your motherboard so I don't really know what manual BIOS options you even have?

My Ez Oc tweaker is locked and can't be enabled, and my bios is up to date. Can't change the core voltage at all.
There's only one option some VDROP thing but i dont think that matters since there aren't the options of vcore increasing and other stuff. I'm also getting the COOLER master tonight so for temperature im gonna be quite good for the 3.0 ghz if i ever get to cus of my bios, if im right.
