hi below mentioned are my pc specs.


Operating System : MS Windows 7 Ultimate 32-bit
CPU : Intel Core 2 Duo E7500 @ 2.93GHz Wolfdale 45nm Technology
RAM : 4.0GB Dual-Channel DDR2 @ 373MHz (5-6-6-17)
Motherboard : Gigabyte Technology Co., Ltd. G41M-Combo (Socket 775)
Graphics : BenQ E2200HD (1920x1080@60Hz)
NVIDIA GeForce GTS 450

i have overclocked the cpu to 3289.1mhz using the bus speed at 299mhz resulting in fsb of 1197mhz. the temps are fine with idle at 40 degree celcius and max at 70degree celcius and this with the stock cooler but good airflow management. however the reason i overclocked it is because i cant get good frame rates in call of duty black ops at default settings. after the overclock its better but the lag can still be noticed. i have already overclocked the GPU and i dont wish to do much with that as i know its a cpu bottleneck i am facing,

i was wondering if its possible to overclock my cpu more to get better performance i will buy a cpu cooler if needed.but how mocu more can i get from my cpu and how stablewill that be ?

also please check if i should increase the voltage as i have currently set it to 1.28v and as per intel cpu can run till 1.3625v.

You are already at a high overclock for that CPU. The solution for better frame rates is not higher and higher overclocks, but to go to an upgrade in CPU (system) with better performance. Stay away from BSODs.

Nonsense. :)  The E7500, like the E8200 Wolfdales that it is based on is capable of exceeding 4 GHz. I have an E7500 in an EP35-DS3P running at 4.1 GHz, 24 hour Prime95 stable. Leon's limiting factor is his motherboard.

The G41 has a limited FSB. The maximum is somewhere around 350 - 360 MHz.

I have an E6500 (basically same as E7500 with a smaller cache) running at 3.87 MHz in a G41-ES2L. The same chip runs past 4 GHZ in my old EP35-DS3P.

With a decent, but not great, cooler, you should easily reach 3.6 - 3.7 GHz.

Intel's max recommended voltage for the 45 nm CPU's is 1.45 volts.
Here's where the "1.45 volts" figure comes from.

You can learn all kinds of neat things poking about the technical documentation. :) 



Extract of a previous post:
Overclocking G31/G41 chipsets

First of all, the E7500, like most Intel chips, has a locked internal multiplier. That's why everything past X11 does not work.

Second, the G31/G41 chipset is an economy, entry level chipset. Unless you get really lucky, you will not be able to push the FSB freq past about 360 MHz. I have a G'byte G41 board. FSB freq of 352 MHz works. 353 MHz doesn't.

Third, your VID is a little higher than average.

This should be your first stop.
Core2 Overclocking Guide

Next stop should be Shadow's Gigabyte motherboard OC guide:
http://www.tomshardware.co.uk/forum/page-245679_11_0.ht...
It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.

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 or the lowest value possible. 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.

Don't try to OC the memory. What little performance gain that you might get will not be worth any loss of stability. We talk about that here:
http://www.tomshardware.com/forum/251715-29-ratio-myth

That G41 board I mentioned up above? I have an E6500 (same basic chip as yours except smaller cache) running at 3.66 GHz (333 X 11) with a mediocre by today's standards ACF7P cooler. It is stable at 3.87 GHz, but the extra performance isn't needed.

I hope you are correct!

thanks JSC. i tried to change the system memory multiplier as suggested though i dont understand much i found lowest value as 2.50A apart from that there were some other options like 2.00B and some similar values with 'C' at the end. now i am still learning about the overclocking so could you please guide me with which one to select and how does this matter. i have read the core 2duo overclock guide already and have applied what i understood already. Thanks

Look at my C2D specs. Installing a Xmatic Loki I'm running 40 cel. If you have a 7500 you should get faster speeds. Install a new heatsink and fan and go to town. Tip, choose and lower the mem speed in the bios, the change in upping fsb will bring it up to 800. Or get Gigabyte Easytune6 and go to 3.2 on stock cooling with one click. The gigabyte bios will also allow you to get a 17% OC with Intellegence tweeker

Yeah you can push it to 4ghz with a good cooler..
