Im trying to overclock my QX6800 with my new set of desktop components as shown below :

PROC: INTEL QX6800 @2.93Ghz SLACP
MOBO : Biostar TP43-HP
PSU: Gigabyte SuperB 720W
HDD: Seagate 500GB 32MB
RAM: 2 x corsair DDR2 800Mhz

im totally new in overclocking, it will be glad if someone can guide me a bit or tell me where to start as i intended to take my QX6800 to 3.2-3.5 Ghz without any risky adjustment (if possible ) cause i heard that rising the CPU voltage will somehow shortened the life span of the Processor itself.

i've went through some of the article from " Fundamentals of Overclocking, NEWBIES PLS READ THIS BEFORE POSTING " but most of the URL aren't valid anymore so i have no idea where should i start from.

i knew a little bit of how FSB and multiplier works from here URL :Q8200 vs Q6600 if going ....
but still , i have no idea what value of FSB and multiplier should i use to get to 3.2-3.5Ghz for this QX6800

Any pro mind to guide me a bit in this matter coz i really want to get myself into OC'ing and hope that i can be one of those OC Pros out there one day

To make things easier for the pros to review on QX6800, here are some of the features :

u remind me of myself when i was a noobie @@... well, firstly set the multiplier u wanna use (QX6800 ranges from 6~31)...

look at your bus speed... by default it should be 266, hence stock clock for QX6800 is 266x11 = 2.93ghz

to increase ur clock, u can either:

1. increase the bus speed
2. increase the multiplier

for bus speed, for example, if u put 300, it will be 300x11 = 3.3ghz
for multiplier, for example, if u put 12, it will be 266x12 = 3.19ghz

when you oc your bus speed, few things will be oc'ed as well... ram, and your fsb... lets say u put 300, ur fsb will be 300x4 (fsb is quad pumped) = 1200fsb, and your ram, depending on your multiplier, for this case lets use 1:1, will be 300x2 = 600mhz...

regarding voltage, it depends on your proc's capability... u might be able to hit 3.2ghz on stock vcore... but if u find it unstable, u have to add vcore, assuming you are very sure that the processor is the culprit for instability

hope this helps

i guess there are already intel OC thread pinned out there, no need to open a new topic...
and your processor is very easy to OC, just up your cpu multiplier and vcore only, no need any skill for newbie..

Thank you very much for your guide , it really helps.

I'll try it out tonite, and if there's anything, i'll come back to you, lol

its the same... just that, ur qx6800 is alot easier to oc cos of its unlocked multiplier

for the FSB , any value will do as long as it does not exceed 400Mhz (RAM 800Mhz)?

im sorry but there is a Core2DUo thread there.
please use that
