hi... im using A8N-SLI Premium

i set my FBB to 248,Muliplier x11 that means 248x11= 2748

Voltage i set to 1.550V ( MAX ) , Chipset Voltage (1.6V) , HT Voltage , (1.25V)

DRAM Setted to auto: 233MHZ 3.3.3.8 using Corsair TwinX CMX512-3200Pro
DRAM Voltage 3V

HTT multiplier X4 . 248x4=992

but the problem is....no matter how set .... when i overclock .... there will be cackle in my sound ..... and at the startup hang ... till need to reset...

even if i set AI OverClock at 10%...it still got the cackles and hang...

any1 can share some settings ?

A8N-SLI PREMIUM

sorry i cant paste CPU-Z becos system hangs at loading

ur mobo support pci-lock which means pci speed is constant at 33Mhz even if u oc?

aint PCI graphics? i capped that at 100MHZ at BIOS..

and i dont think my mobo has pci-lock...asus .....

asus a8n sli premium sure got pci lock ..

it means you have pass any hardware limit...the hardware limit may come from Ram, Mobo, and most of the time CPU....

Try to lower your CPU multiplier

how come u set the voltage so high? try to lower the voltages to stock and try overclocking. dont use AI nos as it sux

err..how about try to update ur bios..

wats this value? ijm not sure wats u r talkin ab...

DRAM Setted to auto: 233MHZ 3.3.3.8 using Corsair TwinX CMX512-3200Pro
DRAM Voltage 3V
HTT multiplier X4 . 248x4=992

how about....
1. setting the RAM timing to 166 or 200mhz.
2. loosen the RAM timings to like 3-4-4-11
3. reducing HTT multiplier to like X2 or X3

in short - lower all the settings 1st la. then slowly tighten it.

kk...will try...but for voltage isit ok if i put all max at the beggining?

up little by little until u get a stable voltage....

i found out that if i set my RAM frequency at 200MHZ..it fails to boot...and this womens voice pop up saying : "Sytem Fail Becaus of CPU Overclocking" but again i set 200mhz and 3.4.4.11 and DRAM voltage set at 3V/Auto.....it works well if i set it to 266mhz 3.3.3.8

Got voice?Did you lower the vcore and try raising it little by little until stable?

I guess your Vcore too low for a 2.75ghz. Need to reduce abit.

Try setting memory to 2T instead of 1T. See if that helps stabilize things.

wasn't ur voltage setting to high

Nope I think the vcore just about nice unless he is using stock hsf.

TwinX CMX512-3200Pro <---- what chipset?

when u ocing

dun set any timing too auto mode...
maybe fail to boot
