Specs: Windows 7 32bit, E5700/3GB
, im currently oc e5700 @ 266 x4 fsb, multiplyer @ x13 using stock cooler, i get temps max of 62/65 degrees during gaming, is this ok temp? Is there better fsb settings for this cpu??

and will it be worth while for me 2 upgrade my motherboard from Intel G31 to a G41 chipset? will it improve gaming??

Many Gigabyte motherboards in their BIOS' offer a 'Memory Multiplier' which is probably your 2.66, 3.33, 4.0 settings. These choices vary depending on what the frequency your CPU is supposed to run at, for example, if you had a CPU with a naturally higher FSB you would be offered a different set of choices, specifically lower ones. You can try this and see if you can fool the BIOS into offering you a different set of choices on your memory multipliers: Set your frequency to 333 and your memory multiplier to the lowest (2.66) and your CPU multiplier to 9, then save changes and exit, but when it reboots, go directly back into set up rather than into Windows so the higher memory setting should not matter, and see if you are offered the 2.0 memory multiplier option now. If it is, then you are all set, if it does not, then you will either need to limit your OC so your memory does not increase beyond 800 (or whatever it's design limits are), or look into overclockable memory that can tolerate the higher rate. As far as the ratio is concerned, the ideal is 1:1 or 1:2 (many even dismiss this completely), but if you cannot achieve it, your machine will actually run very well at a ratio of 3:4, in fact I have run a machine OC'ed at that ratio with a similar issue and it ran very well. Later I swapped out the CPU for an E7500 that I got a decent buy on (Microcenter) and since that has a higher base FSB, the RAM speed issue was solved (it is only the 800MHz FSB CPU's that are as limited on the memory multipliers offered on the Gigabyte boards, the 1066FSB base CPU had batter options).
Edit: Just also thought: you can use a Frequency of 300MHz and a CPU multiplier of 11 for 3.3GHz and that would give you 300x2.66=798MHz DDR2 RAM freq. and a 1200MHz FSB and keep you within your memory limits, increase your FSB, and that should be the same ratio you currently have. Many will object that it is not an ideal setting, but it is a workable setting, should give you a performance improvement, and is not really that 'bad'.

You have to be a little bit crazy to keep you from going insane.

You have not included all specs, but you should try freq 333 (333x4=1333FSB) and for a multiplier, start with 9, then 10, and if the temperature is reasonable and it is stable, try possibly 11. With y0our RAM running at 667DDR2 (333x2.0) for a of ratio 1:1.
9x333=2997MHz=3.0GHz
10x333=3333MHz=3.33GHz
11x333=3666MHz=3.66GHz
If your max temps are mid 60's C, your normal 'working' or browsing is in the low to mid 50's, and your idle is more like the low 40's, then you are fine in the temperature department, but lower is definitely better for long term durability.

You didn't list the make/model of your board or the type/speed of RAM you have. For best performance, the CPU:DRAM frequency ratio should be either 1:1 or 1:2. Which one you should be using will depend on your hardware. With the CPU frequency at 266MHz, the RAM should be run at either 533MHz DDR or 1066MHz DDR. At 333MHz frequency, the RAM should be either 667MHz DDR or 1333Mhz DDR. If your board can handle 400MHz frequency, the RAM should be run at either 800MHz DDR or 1600MHz DDR.

Gaming depends heavily on the graphics. If you're still using the onboard Intel graphics, your gaming experience is going to suck no matter how much you overclock the CPU. Upgrading the motherboard will have little effect, you need a decent gaming card.

ok, my motherboard is GA-G31M-ES2L. my ram is crucial pc2-6400 = 1x 1gb and 1x 2gb modules.

my motherboard only allows ram changes of 2.66, 3.33 or 4.0 in the bios. so when i set fsb to 300 x4 my ram auto goes to 800mhz and wont let me change it, My ratio is, 3:4, is this ok?? i cant get 333fsb because then my ram will run @ 880mhz automatically.

im using radeon 5570 gddr5 graphics card, oc'd core 650 to 710mhz, temps max of 65 in games.
