what have i been mislead by my greed

[polarbear6]

hey guys,

i have a e8400 chip on a gigabyte p35 mobo
this mobo is a 1600fsb mobo

now the thing is iam overclocking my e8400 but i never manage to rise above that 1600 fsb mark(400 * 9)
does this mean that
the board which says 1600 fsb means that its the max ??

but on contrary to this
i remember taking this same chip e8400 on a g33 to 400 fsb (1600 fsb) but that board was a 1333 fsb board

CAN ANY ONE TELL ME THE MEANING OF THIS FSB OF THE BOARD
i know that this fsb = external clock * 4 (quad pumping)

but i see no use of this figure

and do pardon me for being a amateur

just a rating, once you go past it, you're overclocking the motherboard...

Like 800mhz ram at 900mhz, or a 333mhz e8400fsb at 400mhz, you get the point...

ohhhhhhhh k
so then why do i get a blue screen always when i try to go to 3.82 ghz (from 400 to 425fsb)
i even tried pumping some more volts (1.218 to 1.25 volts)

its like when i oc thru my bios and i try to boot into windows

and i even make it thru the POST and when i see the windows starting thingy i get a blue screen and my pc restarts

and it is the same with the in-windows ocing

Here is the stickied overclocking guide to help you: C2D Overclocking guide.

I figure this will be of use to you since you are asking such basic questions. Once you get through that, if you still have questions you can bring them up again.

Yes read the guide for sure. You will need more voltage for what you are trying to do.

the FSB and the NB voltage need upped, as well as (possibly) the cpu. Also check the memory multiplier. Make sure its set at 2.

I think you're getting confused by Intel's marketing terms (imagine that).

Quad-pumped fsb is exactly that - 4 x fsb. When they talk about 1333 fsb or 1600 fsb that means the system fsb actually works at 1333/4=333fsb and 1600/4=400fsb. So your "1600fsb" motherboard means it can handle 400fsb.

The e8400 runs "1333fsb" stock - meaning a system fsb of 333. You can overclock it to "1600fsb" or system fsb of 400 for a clockspeed of 3.6GHz (9x400). Beyond that you may exceed the limits of the motherboard, the P35 chipsets weren't known for pushing as high as the newer P45 boards tend to do.

Follow the linked guide, there may be some other tricks you can use to get more out of your cpu/board (increased northbridge voltage, for one, will often allow higher stable fsb). Just understand that with more volts comes more heat and higher chances for damaging your gear - damage that most likely won't be covered by your manufacturer's warranty.

Personally I overclock my stuff just to the max it will run stable without upping the volts.

well i read that and i didnt expect the voltages to be that high

i was like thinking that 1.25 volts is the maximum safe voltages permited (a psychological interpretation of my situation)

but hey what is the maximum speed people have touched with a ocz vendetta 2 ??

and thanks denithor i think know whats fsb a internal and a external clock and whats spd
and what s a 1:1 mode
i dont usually venture out after the 1:1 mode (iam not a ram oc freak )

IIRC the Intel recommendation is 1.3625v (after vDroop, naturally) but folks tend to stretch that a little and some will argue 1.4v+
