I have recenly build up with S939 system and i think i maybe happy with it.

Unfortunely it make me felts troble for it when i want to OC.
I only can use back my default FSB and speed which is 1.83ghz and i cant go for more. Have 1 time i remeber i can go for 1.9ghz only, then its cant boot up and i have solve it by clear the Cmos.

My system is AMD WINCHESTER AHTLON 3000

Mobo i am using Asus-A8R-MVP.

But i never OC my ram So far because i wonder its may bring affects to my performance when i am wrongly config with it.

i am using stok HSF and IDE load is 38c full load is 45c.

So can you help me to solve it?

you have to raise the vcore

be very careful with that reply. raising volatges is one thing but must be within acceptable limits. The current recommendation is not to go over 25% of the stock voltages. Usually the voltage is increased only to strengthen the memory controllers when one starts to up the VDIMM. Otherwise I've noticed for general overclocks for normal use would run well at stock voltages.

For overclocking, safest is to go in 5Mhz steps of FSB as it's easier to diagnose the problem. In fact serach around the various forums on how to overclock for AMD

Here's an example of a decent guide

you may blow your power supply if your power supply is no good one...

if not mistaken, its an ATi board..
plz list down what else did u tweak besides fsb..

possible solution:
1. change ram CAS timing to 3 /adjust ram timing
2. lower the LDT to 4
3. ...
... read mobo manual n understand what each option do
n last but not least, dont play with vcore if u have no idea what u r doing

profit?

The bios setting is like this :
PCIE FREQUENCY 100
Processor Multiplier set to 11.0 (max can go to 25x)
processor voltage set to 1.3v. (max can go to 1.35v, min is 0.8v)
DDR voltage set to 2.70v. (max is 3.2v, min is 2.65v)
PCIE voltage set to 1.2v (max is 1.5v, min is 1.2v)
Vcore over-voltage (disable)
Southbridge Over-Voltage (disable)
PEG LINK MODE normal
PEG BUFFER LENGTH (DO NOT IS WHAT)
CPU frequency is 200. (max is 400 , min is 200)

currently using I-CUTE 450W TRUE POWER 250W.

i dont think its the problem for me to OCing it.

TQ for your guide.

i will let you know if i fond something misunderstand or stuck with it.

raise FSB, test with Prime95. Not stable raise vcore

You try to set your FSB to RAM speed to 1:1 ratio,since due to built in memory controller,as your ram only Apacer,it may look harder to OC.My friend use same processor with you and ABIT board and corsair ram,he manage to reach 2.4Ghz by only add little voltage,but he force to use 1:1 ratio and can't OC his ram,if not the case will be like you,can't OC at all....

i-cute sucks.... it's no more than a well branded cap ayam.

i have no friggin idea what rams are u using
so:
PCIE FREQUENCY 100
Processor Multiplier set to 9.0
processor voltage set to 1.35v (winchester needs 1.4v actually.. but nevermind)
DDR voltage set to 2.80v (assuning ram is hynix/samsung)
PCIE voltage set to 1.2v
Vcore over-voltage (disable)
Southbridge Over-Voltage (disable)
PEG LINK MODE normal
PEG BUFFER LENGTH
CPU frequency is 200 <-- up this frequency for overclock

now, where is:
LDT multiplier? [5x/4x/3x??]
Ram timing menu/settings?

i am using cap ayam ram. but with new cooler TT VENUS 12, I ABLE TO ACHIVE FOR 2.3GHZ. its it a good try?

now he cannot even go til 1.9 oso leh..

That's why I asked him to read the guide you noob or is my english too advanced?

LDT multiplier and ram speed is the reason. Lower both down.

Make sure LDT X HTT <= 1000

good job

you probably can tweak a little bit .... but Winchester are known not to clock too well compare to Venice. some Winchester may do wonder, but most dont.

The bios setting is like this :
PCIE FREQUENCY 100
Processor Multiplier set to 11.0 (max can go to 25x)
processor voltage set to 1.3v. (max can go to 1.35v, min is 0.8v).....minimum set to 1.4v
DDR voltage set to 2.70v. (max is 3.2v, min is 2.65v)
PCIE voltage set to 1.2v (max is 1.5v, min is 1.2v)
Vcore over-voltage (disable).......better enable, but have risk, normal vcore below 1.6v is still safe
Southbridge Over-Voltage (disable)
PEG LINK MODE normal
PEG BUFFER LENGTH (DO NOT IS WHAT)
CPU frequency is 200. (max is 400 , min is 200)

SLI motherboard use much more power, depend on your vga card
better with a nice PSU

yup its true..regarding on the power comsumption..try use speedfan, u can see how the voltage variation..since speedfan is easy to use..some how u will understand why soulfly means by telling u dat icute just a branded..but still cap ayam in performance cheers happy oc

i will try to settle my VCORE bug as my VCORE max only achive to 1.4v o9nly.
is there any ways to settle it?

whats PSU is better to use?

check out dinster bulk..usually psu with support sli stated "SLI ready"....but somehow if u using non-sli ready psu also can what..based on my reading on other forum lah~ since SLI ready PSU comes with Big Money ready lah~ fortron or sansun seem like a nice choice
