I wanted to know how much can they be overclocked to
and even after overclocking to that level can they be stable.

How much can the Bus be over clocked.

Config i am using with this CPU
Motherboard Used ASUS A8N-Sli
Kingston HyperX 2-2-2-5-1 (CAS Latency 2) Unbuffered
KHX3200ULK2/1G 1GB 400MHz DDR Non-ECC CL2
Dual Channel Kit.
XFX 6600GT PCI-E x16 GPU [1 card only]

Normal Fans used not special cooling kit.

I wanted to know what all things can be overclocked and
will my system run stable with this overclocked state.

i don't know much bout how much you can OC both of them, but it should be very similar (2.8?) however, i don't think ur video card can pair up with ur cpu, i mean u'll spend 1k on a processor and ur performance will be hindered by the fact that you don't have a fast video card. i would suggest down grade ur cpu and upgrade ur video card. =\

The 6600GT is the fastest GPU available in India
The 6800s have not come yet

thats why the 6600GT

That's unfortunate. Perhaps you should wait awhile until they do and save some cash for then. Or i suppose you could just go with what you have and that upgrade your vid card later.

You know, Im not sure about those 2, I've never used either but you may have more success if you post in the overclocking cpu forum

if you're overclocking, getting the top-end CPU is usually a waste of cash, as it won't overclock any further than the ones a couple of steps down. Save some cash and get a 3500+ winchester instead

That's actually not true right now as the 4000+ and the FX-55 both use utilize strained silicon, unlike the rest of the entire line.

@quadmaster: The FX-55 can usually hit 2.9-3.0 on good aircooling, 2.8 on stock. The 4000+ usually maxes at 2.8 on good aircooling and 2.7 on stock. 4000+s are just FX-55s that didn't make the cut, the FX-55 will give you the best performance available from AMD at this time, even after being OCd.

Maxtor disgraces the six letters that make Matrox.
February 17, 2005 10:27:17 AM

I thought the 4000+ was just a rebadged FX-53, and the 55 was the only one with improvements?

That said, I also forgot that the FX has the unlocked multiplier, which does make it a good choice if money is not a concern...

I still don't think the FX-55 is worth the extra $, even if it does OC slightly more. a 3200+ or 3500+ should be able to get to 2.6 with a little effort, and costs a fraction of the price.

why don't the guy try ordering parts and ship them over sea =D... or do most websites ship on US or somethign o.O

I am currently not purchasing and Hardware but wanted to
make sure a certain things before purchasing it.

Thanks for your replies.

Its not that the 6800Gt will not come it does take a time
for hardware to show up here in India.

But doesnt matter.

I have enough time to purchase my hardware around 3-4 months
by that time i expect the AMD processor prices to go a
little more down.

Has the 4000+ & FX-55 have unlocked multipliers.

I asked about OCing because as each Processor 3500+,3800+
is OCable then why not 4000+ & FX-55 it also could be OCable.

At least the FX55 has onlocked multipliers - I think the 4000+ is unlocked, too.

I thought only the FX series are un-locked.

I thought the 4000+ were unlocked becasue they were redesig FX-53 or 51. But you could be correct - just don't remember right now.

they are rebadged, but AMD will lock the mults, so you can only use the lower ones.

Are the mmultipliers locked for both + & FX
What about a little old + & FX versions 3200/3500/3800
& 51/53

FX are unlocked, all other Athlon 64 are locked.

Only the FX chips are completely unlocked. All the other chips have a max multiplier, but you can use lower multipiers, for OCing, if the mobo supports it.
February 19, 2005 1:42:19 AM

Only FX series has unlocked multipliers to OC up.

So no OCing for AMD A64+ Series.

What are maxmultipliers.

Does the ASUS A8N-Sli Mobo support A64+ Series UPward OCing.

I dont want to OC Lower.
