overclocking amd 2800 athlon xp

ok, i need the heater core and a pump (from a car or one for pc) you much did you spend on that brand new or second hand (like a junker).

let me know please so i can get the proper hardware then ill ask for installation details later.

You should try mounting your radiator outside your house or in a remote room to keep the room your computer is in from over heating. While you're at it, you might as well hook up the water cooler to your Northbridge and video card, and if you can jimmy-rig something, surround your power supply and maybe the HDD(s) with some kind of heat sink. Now I'm fantasizing. I just think it would be cool to try empty most of the heat from inside the case to a totally different location. Just think: no fans… a silent computer. My room gets really hot in the summer and spring from my computer. Maybe I could set up the radiator in the intake vent of the central AC. Hmmm, this sounds like a huge project. I will make it happen, some time…. and I will be sure to tell you all about it.

 

Hey, Chill, chill with all that O wow man.

Radiators are what you need, yes, we all need. Problem is if you are going to dump all your heat some place you have to use pumps.

I would prefer a peltier solution with water cooling myself, but I cant be bothered what with all the other stuff I have to do to set it up yet.

Sorry to say this but my mobo, cpu solution will NOT overclock my 2800XP (on air). The problem is simply that I have a stubborn CPU.

 

hello tcialek
ok ill wait until you get it done sounds like some big project but personal satisfaction of building your thing is what counts thats the fun off all this!!

(did i get too sentimental...jajajaja).

the think is my place got only two rooms i have no space so i need to plan that very well.

will keep in touch.

 

Hi all,
just joined and have enjoyed the thread, but I am new to the OC'ing, and I am curious how to do this easily and safely. If I hit the 2.2 ghz stable I will be happy.

I guess I am a little confused with the whole 'multiplier' and the possible need to adjust the vcore.

i'm now wishing i had the 2500+

any help you can supply would be great. I have no intentions on water cooling, I'm just trying to make what i have last until i go nuts with a new system and PCI vid.

Thanks,

Jagerbreath

 

Hey y'all
question for youse: my bios is set to 1.80vcore but asus probe shows in hopping aroung from 1.84 to 1.856???? I would assume personally that the bios is right on and asus probe is?????not???? or am I looking at fry city?

Which begs the question: if temps are ok why not raise vcore?

Running AThlon XP 2800+ barton oc'd to 2.39 Ghz.
Asus A7nx8-e
Temps: 46c idle 55c load with Thermaltake volcano 11 @~3500 rpm (otherwise my case leaves the ground..

thanks for all good info.

 

hahahaha, yeah nice one.

I got the Volcano 12 and it sure is a noisy mother at 5500rpm.

Don't worry about the fluctuating Vcore voltage in Asus probe, mine does it all the time.

 

hi, welcome jagbr to the forum.
there are several ways to overclok first you need to know your hardware to know how much you can pushit without damage your syst. ok

athlon 2800+ barton (lock core)
your cpu has 12.5x mult and 166 internal bus (12.5 x 166= 2083mhz thats your cpu stock speed) thats what mult is part of clock speed).
in barton core are lock which means you cant change the mult. all you can do is change the internal bus
166mhz or the vcore,raising that will make your mobo to give the cpu more voltage ( which i dont recommend because is really dangerous).

first lets look at your hardware:
mobo: asus a7n8x-x deluxe is really great oc favorite board.that mobo will let you change: vcore,fsb.
memory: your mem is great for oc too try low latency timings(Cas: 2-2-2-5-1) and those mems have an aluminium heat spreader.

cpu cooler:
this is very important when you overclock you are stressing your system which cause your cpu to overheat so a good fan and heat sink are need it ( you didnt mention your cpu cooler??) athlon xp die temp is 85cº according to amd.

you want 2.2ghz the xp 2800+ can easy handle that (personal experience).
try this fsb 176mhz with a mult 12.5 = 2200mhz.
remember to use asus motherboard probe app to monitor you cpu temps and set shutdown temp warning on your bios(just for protection 2.2 is not much just in case).
and try to put some case fans too that helps.
final note: oc is a matter of try and try until you get the highest and stable settings!!
let me know!!
hope i help.

Hey, very good explanation of O'Cing in general. But yes, just like he says. It's a factor of just trying to OC your system till it shuts it's self down, or you can a temp gage as I do. To see how your system is handling the change.
Personal experience, don't OC something you don't have the money to replace it with.
I've soft modded my Radeon 9800pro, to xt. With out any temp. changes, I was shocked, then I sold it on ebay as an xt. I did explain the softmodding. The person that had bought it still emails me till this day. Going on 8months solid xt performance.
I did not see any difference. From 9700pro to an 9800xt. So I of course am still using my 9700pro until I am impressed with a newer card.
I have a nf-s v2.0 board, in which I showed that I have a 2800 Barton chip. OC'd to an 3200 at 400fsb with stock cooling at a temp of 48'c, 50'c under load. To me OC'ing is fun if you know what you are doing. Knowing where your cmos reset is, is the key also to OC'ing. So you can reset your system to defaults at any time a bad OC has happened. You will know. As system shuts down, and monitor will not kick in. Time to reset cmos.
But hey, Once again, good luck with your person OC'ing. And never go off of someone else OC. Because a lot of OC'ers know it's for bragging rights, and most are bullshiting you. So watch!!

 

hey ace!! how you oc your 2800+ with 400 fsb in stock cooler men!!!! and those temps how???.

i have mine on 2.21ghz (176bus,12.5mult)
cooler gigabyte 3d cooler max speed 4400rpms and i get 39-43 temps i want to pushit more but my memorys wont let me! (markvision pc-2700) 2.5-2-2-7 cas.

Well, like I said in my previous post. With this nf7-s v2.0 board, it was just a touch of a button. From 2800mhz 333fsb, to 3200mhz 400fsb.
If you can tell me how to give you more proof in what I am doing, please tell me. I have a couple of utilities, this being the 2nd showing the cpu's change in just seconds. Thanks.

Hi aceprowl,

Im am glad to see some info on your OC. Thanks for letting us take a look.

The problem with my system is the CPU wont allow me to go further. Here is the stepping information on my CPU;

AXDA2800DKV4D
AQYHA 0408RPCW


Operating Voltage 1.65 V
Max Die Temperature 85° C
L1 Cache Size 128 KB
L2 Cache Size 512 KB
Multiplier 12.5x
FSB Frequency 333 MHz
Stepping Code AQYHA
Manufacture Year 2004
Manufacture Week 08
Production Batch C
Batch Production Number 0308

Mine is locked and wont budge. (after week 38 2003)
What is your stepping and production week/year?

Hi Dr Xp,

I would like to ask, why do you believe that it is a bad idea to increase the Vcore? Didn't someone say that increasing the voltage makes the transistors switch faster? This is why you need higher Vcore to overclock. The problem is more heat is generated and so you need better cooling.

If you want to overclock you need to increase the Vcore, not so high though that the temp is too high.

People who have mobile athlons can overclock to XP2800+
speeds easily, but stability requires about the same Vcore or less - 1.65. These cores are perhaps better quality and can overclock to higher speeds without generating the higher temps. Extreme overclocks need the cooling though.

A vcore of 1.8 should be fine.. (If it is available on the bios setting of the conservative A7N8X-E deluxe then it must be OK!)

I use motherboard monitor 5 to check in windows what is happening to Vcore with the Hi/Low record. I have noticed that under full load the Vcore can be as low as 1.73 and go as high as 1.79 when set to 1.82 with my power supply.

Going above 2.0V is probably a bad idea, I dont, and Ive no idea how quickly burnout or lockups result.

 

Hey phredcong,

lol - I use a thermaltake, mine was just as bad. I took off the fan and put a normal case fan.

I reckon they just like you to think its working by using a noisy fan that you can only ignore when playing games..

You have a similar setup to mine, though I guess I have a power supply that is different. (what do you use?) 1.85 Vcore is already quite high and the temperature (where do you get that number from? 55C) might not be accurate if read through the ASUS bios or ASUS monitor.

Get more volts.. (1.825 Max in bios ? 1.87 from sensor)

At 2.39 Ghz you already leave mine standing..

 

Hey Dr. xp

Just wanted to thank you and the others commenting on my questions. I added my current fan info to my signature. I believe I have a good enough fan to cool it plus a couple other case fans.

Previously running around 2.0 ghz

Now at a seemingly stable 2.21ghz (177 fsb x 12.5)

I'll go play some HL2 and pass on the results. Is there known stability @ 2.5ghz? heh, i stroke a couple keys and I want to go further, lol

The forum is great, keep up the good work!

 

HELLO MOLKS!
LOKO FIRST AND MORE IMPORTANT YOUR MOBO LETS YOU SWITH THE VOLTS THATS RIGTH BUT THEY ALSO SAID THEY ARE NOT RENPONSABLE FOR ANY DAMAGE YOU CAUSE TO YOUR CPU OR MOBO (THATS IS DO IT AT YOUR OWN RISK THING).

AMD RECOMEND NOT TO INCREASE YOUR VCORE BUT IF YOU DO DONT GO OVER 1.8 VOLT.
IN XTREME OVERCLOCKING YOU NEED TO INCREASE VCORE IN ORDER TO COPE WITH HIGH FBS SETTING CPU IN THAT CASE GET VOLTAGE HUNGRY SO THAT THE XTRA VOLTAGES FOR.

BUT IN LITE OVERC JUST BY INCREASING YOUR FSB WILL BE ENOUGH.

WHY INCREASE VCORE CAN BE DANGEROUS EASY BECAUSE ELECTRICITY BURNS,FRIES ETC.. VCORE IS VERY DELICATE CPU PART YOU WILL GENERATE MORE HEAT FROM VCORE INC THAN FROM FSB. BUT IF YOURE PLANNING TO TAKE YOUR CPU TO THE MAX THEN AND ONLY THEN IT IS NEED TO INCREASE THE VCORE.

OK NOW ABOUT MOBILE PROCESORS THEY HAVE UNLOCK CORES
AND LOWER FSB EXAMPLE A LOCK 2800+(266 FSB,LOWER VCORE 1.45V AND LOWER CSPEED) TO LET YOU TWEAK IT!!! AND UNLOCK MULTIPLIER. THATS THEY ARE FOR OVERCL.

THATS THE REASON NOT HIQLT CORES.

ABOUT MONITORING I TRUST THE BIOS NOT MOTHERBOARD PROBE. MOBO PROBE IS TO GIVE YOU AND IDEA MINE HAS A DIFFERENCE OS 2-3Cº, 0.5VOLT (BIOS-PROBE) SO GET IN YOUR BIOS AND COMPARE IT WITH YOUR PROBE.
FINAL NOTE: DUDE DONT RAISE YOUR VCORE TO 2.0V..

THANX JAGERBRTH GLAD I HELP ANY TIME MAN!!
LETS!! KEEP TWEKING!!!

sorry

 

Hey molks,

My bios is set at 1.80v, its the asus probe that reads 1.84~1.85. I also use the ASUS probe for temp monitoring...who knows if it's accurate...? My power supply is a RaidMax 400W that so far seems to have enough juice. I hope to add a 2nd seagate barracuda 120gb and go to RAID 0 after santa's elves get it together . maybe then I'll need a bigger power supply.

So yea, ur multiplier is locked at 12.5 but you can increase the fsb (mine is set at 191 mhz. atm). I tried (for kicks and grins) to go all the way to 200mhz x 12.5=fsb400mhz=core2500mhz (!) and it would boot into windows but Prime95 wouldn't run a single iteration...I took the hint and backed off! So, with a little experimentation 191x=382mhz fsb=2.387ghz was stable running Prime95 for 3 hours (i know not overnight, so who knows?)

Also, my ram is PC3200 400DDR so it handles the extra speed in the fsb without oc'ing itself (in fact its below its rated speed) and that will definitely contribute to memory stability not being an issue.

hope it helps, post again if u want me to share what little more i know..

ps, yeae if I increase my bios asus probe is always about .05v higher than bios. why, no idear.

 

So...Gentlemen,

I'm looking for an opinion on whether or not i can push my processor to 200fsb and 2.5 ghz from the current state of 2.2ghz.

Any one have experience with this and a similar configuration?

Totally new to trying to ruin my puter,

Jag
