    overclocking a e6300 questions

    Hi I am planning on OCing an e6300 using the stock cooler at first until when I order a better CPU cooler.

    The motherboard I will use is a MSI P965-PLATINUM iP965 with 1 GB ddr2 corsair xms2 800 MHz.

    Now I am a total noob in OC and I have read a few pointers to how I can OC a CPU.

    I have read that I would need to OC the CPU first and than the memory.

    Cant I OC both?
    Quite a few places I heard have stated that they OC their cpu from a fsb of 250mhz to something above 300mhz which according is around 2.somthing GHz in regards to the 1.86ghz that this cpu is currently stocked at? How can this be? Doesn’t the e6300 start at an fsb of 1066 MHz fsb? Why do people OC it down to 300s or am I missing something?

    People also say that the fsb of these CPU’s are around 250 MHz at stock level? Why does it say on the box that its 1066?

    Thanks in advance and hope someone can clarify this please, thanks.

    Im entirely new to this aswell. Forget the 1066 for now thats motherboard wise.

    CPU wise - There is the FSB and a Multiplier- For Intel its FSBxMultiplier. So eg 250 x 7 (E6300's Multiplier) = 1750Mhz.

    This also ties into the ram, eg if the RAM is set to 1:1 the ram will run at 250mhzx2.

    The 6300's clock lovely, i would put the FSB (CPU) straight to over 300 as it should easly do this on Stock volts and tempertures will still be fine (unless already high on stock) It should easly boot at FSB= 310. If it doesnt reset your CMOS but it 99% of e6300's will easly boot at this.

    So then you new speed will be 310x7=2170mhz. Most 6300's will hit 3Ghz on decent cooling (with some higher volts i would expect)

    RAM- You could set this at 4:5 or Just leave it as it is. Even 1:1 would be fine at an FSB of 310.

    Hope this help's - Remember im new to it aswell. But i put my 6300 straight to 340 to test for 5 mins and it was fine, 27C

    so let me guet this straight, with my ram it says its 800MHz so that means 400Mhz x 2? does the fsb for the memory need to run at the same fsb has the cpu? what happens if i leave the ram at 400MHz whilst the cpu is at 310?

    thanks that bit about the cpu makes sence now. btw how did you know the Multiplier is 7 for cpu and two for ram?

    the 1066MHz FSB comes from the stock speed of 266MHz quad pumped to 1066.

    If you set the ratio of ram to fsb to 1:1(highly recommended) the speed of the ram will increase as your fsb increases automatically. So if you get your fsb to 400MHz your ram will run at max stock speed of 800MHz. If the speed of the fsb goes beyond the stock rating then you might want to relax your timings (5-5-5-15 rather than 4-4-4-12).

    by default does the ration of the ram set to 1:1 already? my ram is already at 5-5-5-12

    So the lower the ram timing are eg 2-2-2-6 the more higher the memory can be OC'd?

    by lower i meant higher numbers (slower performance) u may need to try 6-6-6-15 or 6-6-6-18, u can increase each one individually until u get a stable boot. Things vary from component to component.

    Your ram shouldnt really struggle. If more help is needed post here and i advise getting CPU-Z (http://www.cpuid.com/cpuz.php) download it run it and post screenies of the information.

    ok thanks for your advice guys im gunna give this a try tomorrow by increasing the fsb up to 300MHZ. that should OC both the ram and cpu together.

    That will get you to 2.1GHz and the ram running at 600MHz.

    I have read that I would need to OC the CPU first and than the memory
    The reason for this is that your cpu will most possibly overclock to a higher frequency than your ram can.
    eg your cpu might overclock to 500MHz from it's default 266MHz, while your ram may struggle to reach beyond 450MHz.
    By overclocking your cpu first, you find out its potential, then you find out the max potential of your ram. If you overclock both together you won't know if it is the cpu or ram which has reached its limits.
    I suggest you run your ram on a divider to half it's stock frequency, then overclock your cpu, running your ram @ 200MHz rather than 400MHz will remove the ram's limitations as a bottleneck.
    Once you have found your cpu's ceiling, you can then make note of it, set your memory back to 400MHz (and cpu back to 266MHz) and find your ram's max frequency.
    Then you can either run both @ their max with a memory divider, or lower the cpu frequency in-line with your ram's max frequency and run @ 1:1.
    Using benchmarking software such as Sisoft Sandra will show you which will give you the best performance.

    I have had a play around OC'ing the fsb from 266 to 300 with the cpu temps at an average of 36-39c

    by the way, does anyone know of a program that can monitor the components inside the pc such has cpu temps and the amount of power going into the psu? thanks guys

    I suppose that's as accurate as its gping to get.

    Best to use one and stick to it.
