at stock voltage, i can do 250Mhz * 9.5 = 2.375ghz... my mobo is tforce 6100 with latest bios...nvr tried higher voltage coz scared will burn...my old athlon xp alrdy burned as i up the voltage...

now i enable CnQ, only can boot at 230Mhz * 9.5 = 2.185ghz... any1 got tips for higher speed with CnQ?

@ all

i want to overclock my pc... and im still an amateur(juz ovrclck using to implemented software). will u guys teach me how? and what should i do to my standard pc to overclock it?

man, i got athlon x2 3800+ @ run at it should be(standard) / asus m2n-e / 2xCorsair 667 ddr2 512mb / enlight 350wt / xpertvision/palit 7900gs / seagate 160gb;maxtor 80gb.

firstly, go into ur bios, and find the HTT or FSB speed...default is 200mhz, jz make it go higher step by step...maybe 10mhz at a time...
but remember tat the total HT speed must not exceed 2000MHz (200 HTT * 2 * 5 which is the HT multiplier)...when u move above 200Mhz for that HTT/FSB, u must reduce ur HT multiplier frm 5 to 4 and so on...

I believe brisbane can 2.6ghz with stock vcore.
Keep on pushing pal!

for Biostar TForce user, how do u lock the PCI bus speed?
is there any newer BIOS that provide it or must do it thru ClockGen?

with 1.4v u can achieve 2.9ghz...
and again oc with CnQ enable sometimes not very good... coz if the voltage not supply correctly for certain speed.. the comp will hang...

@ smokey

thanks.. btw, i dun use any cooling solution..just the standard fan.. my proc temp is at 40/42 idle.. load around 49.. the max temp 4 my proc is?(x2 3800+)

1.4v wont blow my cpu rite? i vry scared liao..
can run CnQ with 1.4v?

Added on June 13, 2007, 11:39 amthe highest i tried is 259mhz...can prime 32m but playing dota halfway, suddenly bsod...make me become leaver only...paiseh...
duno wat is limiting me.. alrdy use ddr400 and ddr533 but still cant achieve higher..

tf6100-am2 eh?
try the latest bios then, bios 207RH.

RAM timing important too, just set 15-5-5-5(very loose IMO ), CMD = 2 and Trfc around 21 to 26.
Push it again

im using 316 i think...the ori latest bios..

When did bios 316 released eh?
Latest bios served me well

lol.. i even tried 1.55v with 80C..
but for sure brisbane dislike over voltage.. and other temp control which definately shutdown ur pc before kaboom...

8tvt,
how do u lock the PCI bus speed to 33.33MHz?? does ur motherboard (BIOSTAR TA690G) support any PCI bus setting in the BIOS?

BIOS will lock it at 33.33mhz unless u change PCI-E bus speed with clockgen.

If ur oc and PCI bus change, go email biostar for further support.

ic..thanks for the answer..will try oc again with my 570U and see how it goes

yup.. depends on chipset and bios..

luckily my bios board can lock.. otherwise cannot push high..
some board got option, some by default lock.. and worst not even lock..
the lock function became popular since nf2..
i thought this problem not popular anymore..

it's becoz of pci bus.. should remain 33mhz.. if oc more than that sure crash...
the most it's can stand around 35mhz..
the problem comes when oc the fsb.. the pci bus also increase...

let's say 200 fsb... default pci divider is 6

200/6 = 33mhz

if oc 240/6 = ~40mhz..
to make it stable must change to 7..
i observed this one since socket A...

maybe nowadays they just lock it as 33.3mhz...
so good bios programming should be supplied by mobo maker..
i not a technical guy.. just say through experience.. hope that help..

i think the latest bios for tforce6100 am2 is CR51A507 at rebel's haven...
http://www.lejabeach.com/Biostar/6100-AM2/CR51A507.rar
maybe trying it tonite...

Currently most (if not all) boards tie the PCI and PCI-E clock together (PCI = PCI-E /3), and for overclocker boards they are usually seperate from the main system clock. For nForce chipsets, the main system clock is integrated into the motherboard chipset, there is no seperate circuitry.

There is absolutely no reason to touch the PCI/PCI-E clock, as there is very little performance increase and a hell lot of trouble with unstability .

flashed to 507 liao...
now managed to boot at 260mhz @ stock voltage @ without CnQ @ virtualization enabled (wats tat?)...but havent prime yet...
but i dunno y cant even boot at 270mhz @ 1.4v @ ddr400 @ without CnQ @ virtualization enabled (wats tat?)...
y ar?
