How to boost Q9450 speed to 3.2 GHz
How to boost Q9450 speed to 3.2 GHz
Hello everyone, please tell me if I can overclock my Q9450 to 3.2 GHz, I tell you the needed specs and someone send me the settings
Motherboard: P35-DS3 rev 2.1
RAM: 2X1 Gb Kingston DDR2 333 MHz speed
2X1 Gb PQI CORP. DDR2 400 MHz
GPU: GT 730 ASUS 2 GB GDDR5
CPU: Intel Core 2 Quad Q9450
CPU cooler: Aigo ICE200PRO
Thanks! Show me the settings I can make so I do not risk my PC components dying!
Q9450 shares the same 8x multiplier as your E6750, meaning the process remains identical, but you must also raise the MCH voltage. This is because two dual-core processors are mounted together on the same CPU package, effectively creating a multiprocessor setup within one socket. This configuration restricts the FSB's stable speed range, though 400MHz should still be acceptable.
Yes, you can delay the memory insertion, and a slower memory might influence your OC speeds.
Ensure it's stable before proceeding. The 333MHz DDR2-667 is already operating at its peak speed with a stock 8 x 333 = 2667MHz CPU, so there are no assurances it will remain stable at 20% faster than the rated clock. Even with reduced timings to 6-6-6-19 and increased voltage to +0.4v (2.2v), this could potentially reduce the lifespan of other RAM modules.
The rated voltage for that component is indicated by VID. During the CPU's development, Intel determined the lowest stable voltage for normal performance and included it in the CPU design so that motherboards could correctly configure it. Unlike earlier Intel CPUs, each model doesn't have a fixed voltage but a range instead. As mentioned, this information appears on the Hardware Monitor page within the BIOS when defaults are applied. Adjusting the CPU voltage through the MIT settings will update the displayed value. It can be frustrating when some boards simply state the voltage as "normal" without specifying what that means.
MCH represents the Northbridge voltage, which is also adjustable on the BIOS's MIT page. Prior to memory controllers being integrated into CPUs, they were housed in the Northbridge chip. Generally, higher clock speeds require more voltage; for example, a 1600 MHz boost was only possible on stock FSB speeds from X38 or X48 chipsets.
Using 533MHz DDR2-1066 memory would help if you aimed to exceed the standard 400 MHz FSB. A maximum of 450 MHz is considered reasonable for a quad, which would then run at 450MHz DDR2-900. Multiplying by four gives 3600MHz. However, this depends on the specific silicon conditions and your test setup—your results might only reach 433 or 417 unless you use the 1066 memory.
With desktop Intel chipsets for Core 2, it's feasible to configure memory to operate faster than the FSB, but this is only beneficial if you have IGP support (like in G35) or if manual control over the read value isn't available. If your board lacks these features, stick to the minimum 2.00 memory multiplier setting.
