No, there's no difference. I have an OEM barton as well and it doesnt read a vcore so low. I just wonder how AMD could make a proc like that that could be overclocked the way yours is and operate at such a low voltage. I dont think mine would do anything if i lowered it like that, and i'm at 1.7!

That would suck if they accidentally got you a sempron though. What's the use of those anyway. They compare to a celeron or something. Are they making the new 754 and 939 CPUs the new standard?

Well Intel descided to standardize their die size/config probably just to save money, but it seems like AMD and others are going to follow suit.

Well again, who knows how acurate my readout is since at this point I don't "officialy" know what the Vcore is from BIOS since it doesn't tell me.

OK technow cpu is a mistery jejejeje. look what`s your cpu stock clockspeed?.
its wierd at first i tought it was a mobile because mobiles run at 1.45 volts.. but they have 256 kb L2 cache not 512 kb or maybe theres a incompatibility issue between sensors in your mobo and cpu.
one other think technow in your bios monitor screen it does or doesn`t list the voltages in numbers like all mobos do?
aceprowl i was checking the 939 cpus the best cost benefit is the 3400+ there are great combo offers at:

ok maybe is just like ours 1.65 some if you change mobo you will know but is working fine that the important!!.
kolanjoku i think amd is gonna get intel again (my personal opinion) because amd 64 socket 754 and some 939 are more affordable than intel new 775 socket!! even mobos are cheaper ok.
the limitations for amd 64 platform is the via kt880 chipset that doesn`t support pcix 16x,nvidia sli (dual core vga technology) and ddr2. and since the failure of the nvida nforce 3 150 and nforce 3 250 gb the later one intel got a step ahead but war is not over nvidia launch the new nforce 4 that support ddr2,pci-x 16x and sli tech so let see what tomorrow may bring...

939 supports 1Ghz. Hypertransport. That is why I pointed out that chipset. But don't really know if I could afford that chip right now though. I will look into it more tonight.
I started this system out with the NF7(S)V.2 mobo, and 2500barton. I always go with a board that you have the ability to move up in your chipsize. The way AMD is going, they are going to use the 939 chipset for they're top of the line Processors.
Plus it supports PCI-Express as well, in which the 6800's are eating up the competition! I was a nVidia man until the ATI-9700's starting supporting dx9, and so forth, eating up my ti-4600. So got me a 9800pro, and modded it to a 9800xt with a simple flash.
But I will stay with my set-up I have now for another month or 2, just to make sure prices are good. Love my 2800, never did me wrong. I am a very serious gamer, and this has given me the upperhand, and have always owned with it. So when people start catching up to my current system setup. That is when I will move on. hehe.
O, Technow, the 3100+ samprons aren't bad at all. As far is price to performance comparison.

THATS! good. hey aceprowl i see one of your system is a 3200+ barton with 400 mhz im planning to get one i cant go for the 939 a64 right now so ill stick to 462 jejeje for a while so is the 77mhz jump from the 333mhz of the 2800+ to the 400mhz of the 3200+ worth it?
let me know.
hey!! technow theres a review about cheap cpus they review the semprom 3100+ scket 754

With what is coming out, no. I really didn't see that much of a improvement, you figure 33mhz mem, 2,000 mhz speed. The only diffence I have notice is my benchmarks. Gameplay is the about the same. I'd wait, just like I am.

sapphire radeon 9600pro
hitachi deskstar 160gb 7200rpm
magna 500w psu
sb audigy {9400}
i have been recently considering overclocking my xp2800 to a xp3200 so i have been reading up on overclocking cos i wanna make sure i get this right .now i know i have to drop my multiplier down to 11 and up my cpu fsb to 200 mhz from its present 166mhz my question is about the memory at the moment my bios settings say
system performance {user defined}
cpu interface {optimal}
memory frequency {100%}
resulting frequency {166mhz}
memory timings {user defined}
latency times are 2.3.2.6T
Does this mean that when i change my cpu fsb to 200 mhz that the memory will automatically sync with the cpu or do i have to physically change the memory fsb to 200mhz,if so what do i set the memory frequency to, and as i shouldnt have to increase the vcore will there be any significant temp increase .
one other thing my vcore is set at 1.65v the stock for this chip but it never gets below 1.69v and gets to 1.712v in asus probe and in bios is this a problem cos i have read of other people using this board that have the same problem and would this also mean that if i ran my multi at 11.5 to give me 2.3ghz that i wouldnt have to increase my vcore any higher
thx in advance to anyone who can help
p.s what is fsb spread spectrum?

hello swampsneak welcome to the forums:
ok first let get to know your hardware to see what is capable of.
1-2800 xp barton: 2083 mhz clockspeed,fsb:333 mhz(internal fsb 166 mhz), multiplier 12.5x(if your cpu is barton not mobile the multplier is lock you wont be able to change it), vcore 1.65volt( amd do not recommend you exceed the 1.85volts).
2-a7n8x-e: great mobo! very overclocking friendly.
3-cpu cooler: very important hardware in overclocking yours is not rank as a good fan for overclocking,copper hsf a better coolers!!
4-ddr mem: you have a really good mem stick which is very important for stability (fsb/ddr ratio that should be 1:1) ex. if you use 200 mhz it will be the same for your memory since you have pc3200(ddr400 200x2) when running dual channel. try to use tight timmings just change the 6t for 5: 2-2-2-5t.
5- your bios: when you overclock you can do it by increasing the fsb 166mhz-200mhz (try 1 mhz at a time). and higher fsb will need extra power (vcore) to cope with the higher clock cicles (speed). keep in mind that when you increase the vcore cpu produce more heat so you need extra cooling (case fans,silver thermal grease and better heatsink fan than the one you have). try in small increments like 1.65,1.7,1.725,1.77 etc.. amd dont recomend you pass the 1.85 volt (burn chip void warranty) anyway with today board is almost impossible to burn a chip the mobo lock before burning.
*xp 2800+ barton is lock core no multiplier changing. mobiles athlon you can since they dont use the barton core*
*and you need to monitor your temps from time to time get the latest ver. of asusprobe from asus.com. and always trust your bios which is more accurate than anything* athlon die temp is 85 celcius.
about fsb spread spectrum is recommend disable when overc. but read this...

hi dr xp
thx for the speedy reply yes the cpu is a barton therefore the multi is locked above 12.5 .i'm not looking for an aggresive o/c just want a little more proceessing power before bf2 comes out, and i would like to get the full potential from my memory which i'm not really gonna get running at 166mhz i know the HAC-V81 hsf isn't the greatest but from all the reviews i have read on it, it is ok for mild overclocking which is all i want, altho the heatsink itself is aliuminim it does have a copper plug which runs all the way thru the core to make contact with the fins ,and the 80mm fan has adjustable speed control ranging from 2500 rpm to 4800 rpm according to specs but when i turn mine up it runs at 5150 rpm {in bios aswell as asus probe}.and as i was hopin to just drop the multi to 11 and up the fsb to 200mhz which would mean i wouldnt have to increase the vcore as the xp3200 and xp2800 run at the same voltage 1.65v therefore there shouldnt be any significant increase in temps
current temps are 35c-36c idle 39c-40c full load depending on ambient room temp, what do you think ?
and as to my original querie will the memory automatically sync with my cpu when i increase the cpu fsb to 200mhz

hello swampsnake.
about memory theres something call ddr/fsb ratio which you set 1:1 the thing is with the cpu we have (2800+) has a 333 mhz which means that your memory will only run in dual channel at 333 mhz (166x2). this is something i found out some time ago if you want to see memory running at 400 mhz (2x200) can be done with the 3200+ which runs at 400 mhz fsb (internal bus 200 mhz).
of course if you set your fsb to 200mhz and ddr/fsb ratio 1:1 (equal speed between fsb and ddr) your pc-3200 memory will run at 400 but a high fsb such as 200 mhz is not a mild overclock!! and you`ll need higher vcore values.
i have try a lot of settings with my 2800+ my personal xperience (every overclocker has to xperiment try and try until you get where you wanna go). is that the barton core is not to easy and estable to overclock thats why old xp as 1800+,2000+ and the 2400+ runs with througbred core, 2500+ (which run with barton) are the best for xtreme overclocking.
my own xperience is that 2800+ mild overclocking 2.2ghz work better (170,175 or even 180mhz) i have mine running at 2.37ghz but to be honest i dont see the improvement in performance (my experience!)
final go for mild overclocking your fan can handle it if possible try to get some artic silver 5 thermal grease that can cut 5-7 degrees (i use it and it works!!) with your same fan and you`ll be ok if possible get a few case fans!
let me know!!

hi again
and again thumbs up on the quick reply
i think we may have got our wires crossed so to speak lol. as i said, yes the chip is a barton but only the multiplier values ABOVE 12.5 are locked all the values below 12.5 are still available so by dropping the multi to 11 and upping the fsb to 200mz i will still have my dual channel memory and i wont have to increase the vcore

ok let me see..
if you set your mult below 12.5 your pc boot and get in to wondows.
i ask you this because in my mobo a7n8x-e deluxe in the bios you can change the multiplier (as function of the mobo and chipset)
but when i boot my cpu since is lock i get the black screen and bios reset itself!!
some other thing how old is your 2800+ i belive amd bartons made after 3er quater of 2003 are not lock amd lock bartons after that maybe thats your case (if your cpu boots after changing the mult). lucky you
if so yes you can lower your mult an with the same or little variation on vcore you can get it to run.
do it like that try and try until you get the stable settings for your system.
remember to watch the temps!
some other thing for the forum screens your system description go to your account on forums page and fill the fields for signature with your system info and settings so everytime you post dont have to write it again. p.s: if you have a reason for not use the signature discard this recommendation)

just a question... wat program are u guyz using to OC? im just wondering because im trying to overclock alot of my stuff on my other computer which is an AMD 1800+ and im using Sandra 2005 Pro but some error keeps coming up, thus not alowing me to OC anything. Any ideas why this would be happening??
PS. I asked this question awhile back but it was not clearly answered :(
Thanks alot in advance!

HELLO BMX you mean what program we use to overclock??
well most of us including myself use the motherboard bios to do so! either by increasing the cpu fsb, or increasing the vcore or multiplier depending on the cpu..
the athlon 1800+ througbred core is really overclockeable theres people how oc to 2400+.
but let us know more about that system like memory,cpu fan etc.. to help you
let me know

Does Sandra 2005 even let you overclock?
Swamp, i believe there is a new revision for the Asus motherboards (came out last year). It's 1009. that may be because i have an A7N8X-X but yours may almost be the same bios. I may be wrong though
