Overclocking Q6600 question

Intel Core 2 quad q6600 processor
March 10, 2010 at 05:03:26
Specs: Windows 7
Hello everyone,
I am considering overclocking my processor and I just wanted to ask some of the pro's here to what specs should i overclock it?

My specs atm:

Motherboard: MSI P45 Neo (MS-7519)
Ram: Kingmax KLDE88F-B8NU5 DDR2 4 Gb
Running Windows 7 Ultimate 64bit

Here's a sreenshot of my CPU from CPU-Z:

CPU temperature is usually around 38-42C on idle.

Thanks for any answers.

Two things you need to understand:

1. the faster the FSB, the better the performance.

2. the CPU & RAM should both run at the same base frequency.

- the default speed of the Q6600 is 2.4GHz with clock settings of 9 x 266MHz. The base frequency of the CPU is 266MHz.
- you didn't say which speed DDR2 RAM you have but I'll guess that it's DDR2-800. It has a base frequency of 400MHz.
- your motherboard supports up to 1600MHz FSB, which is a base frequency of 400MHz.

So looking at the above, you have both a motherboard & RAM that support 400MHz & a CPU that runs at 266MHz by default. The trick is to get the CPU to run at the same frequency as the board & RAM.

I suggest you start with the CPU at 7 x 400MHz (2.8GHz). But it's not as simple as just changing those 2 BIOS settings. There are numerous other settings that will need to be tweaked to get the RAM & other components (RAM, PCI-e, PCI, etc) to run at the correct speed without over-overclocking them.

The RAM is indeed DDR2-800 (400 MHz).

So, can you tell me what other tweaks I should do first before changing to 7 x 400MHz ?

And thanks for reply.

Lock Pci-e @ 100mhz
lock pci to 33mhz
disable eist aka speestep
disable CIE
disable cia2
after overclock if the system refuse to boot u need to reset bios by using cmos jumper or cmos battery.
sometimes u need to increase cpu voltage to stablize overlock.

edit. Before overclocking cpu make sure ram speed is correct. Which is ddr2 533.

ddr2 533 is the default RAM speed. To overclock, it should be set at ddr2 800, with a 7 times multiplier, as jam suggested.

Kx5m2g do u understand ratio 1:1? Set ram to ddr2 800? What ram speed should he set if he reach 360fsb? U need to understand this kx5m2g when fsb increase, ram speed also increase, that's why i suggest the ram to run @533 first (ratio 1:1) then when he start to pump fsb and stuck to 360 the ram speed ddr2 720 which is 1:1. Many bios i have seen u can adjust ram speed from 800 to 667 to 533 to 400, but not 720.

kuwese: I was saying to run a FSB of 400 MhZ and the RAM at the same clock speed, which would give the 1:1 ratio. A clock speed of 400 MhZ for the RAM yields ddr2 800. Now it depends on the BIOS settings as to whether the RAM speed AUTOMATICALLY changes when the FSB changes. If the two are unlinked, then one has to manually increase the RAM speed. If it's not unlocked, then from what I have seen, the BIOS default does NOT use a 1:1 ratio, though you can often set it to that even when they are linked. Now if you are saying that the OP should gradually increase the FSB, then I would agree.
