overclocking amd 2800 athlon xp

Okami,what motherboard r u using? mine is Asus, so it has the funtion of auto-reboot with the last safe FPS.
and the FPS of my pc is 190, the time is 12.5x, and i put the voltage is 1.7. then i got the speed to 2374MHz.

 

Hey, I have an original AMD XP 2800 thats runs at 2.25Ghz with the 166 (300) Fsb, whats the most someone has seen one of these overclocked to at a safe level. Also would it be worth me getting a mobo with Fsb 200(400) support to overclock it? thanx to anyone that can help
, Rhys

 

alright, sweet, I'm OC'd.

 

Hey can anyone help me on the settings for my cpu? I have an Athlon XP 2800+ (barton core) which is overclocked to a 3000+ but operates at 2.09 ghz. Is there any way that someone can help me with the settings to get it in the 2.2+ range?

 

Increase the FSB more

 

what would i set it to?

 

I think I got mine up to about 192 MHz and it still booted into Windows but it wasn't stable. 2.088 is the standard speed for the 2800+, so I don't think your overclocking did anything. You can try using "CPU-Z" to detect the core speed and FSB in Windows. Also, once you get your system overclocked you can test its stablity by doing a torture test using Prime 95. Both CPU-Z and Prime 95 can be found by google searching those names. If the torture test fails, reduce the FSB and try it again.

 

When i got it to read as an AMD athlon XP 3000+ i just increased the multiplier but i left the vcore settings the same. Should i do something with that to increase it?

 

How did you increase the multiplyer? The Bartons should be locked, unless it's an older one. But yes, you have to chance the v-core to manual setting so you can go and adjust the FSB manualy. And you may have to bump up the voltage a little. Make sure to read all the other messages in this thread.

 

What are some settings that you would recommend for me? When i ordered my CPU it said barton on the cover. Whether or not its old or new is something i dont know. I guess it must be an older barton but i thought there was only one barton core on the 2800+.

 

I heard that in the last few years they started locking the 2800+. I don't know much more than that. What main board and ram are you running?

 

I have an ASUS A7N8X-X Nforce2 Board and i have Kingston Dual channel 512 MB PC3200 DDR Ram

 

Ok, in the advanced chipset features in teh bios set the following things:
CPU Frequency Multiple [AUTO]
System Performance [USER DEFINED]
Memory Freq. [AUTO]
Memory Timings [OPTIMAL]
CPU V-Core Setting [MENU]
CPU V-Core try somthing like 1.700v... nothing too high or youll fry your chip... stay under 1.800

Now you can go back to the top and change CPU external to whatever you want. I would try somewhere around 175 MHz for startes. Test it with Prime 95 to see if it's 100% stable.

 

hi i have a 2800+ (2.083) i want to oc so let me see if i got it right.
my cvolt is 1.65v i have to increase to 1.8?
that will only oc the cpu or the whole system, or i have to do that and the fsb(166) to or just the volt??


Dr.xp
abit nf7
athlon xp 2800+(barton),gigabyte 3d cooler pro (4800rpm) dont mind the noise
512 ddr (256x2) markvision mem`s(sorry for that)
maxtor 80gb 7200 rpm,gforce fx 5200( crap)

 

The thing you have to do to overclock is increase the FSB. Increasing the voltage is just to account for the extra power you're using. You might be able to get away with leaving the V-Core at its default voltage, but from what I understand, the system may become unstable. So yes, increase both the CPU External and the Core Voltage.

 

ok small increments or specific numbers??
ill increase both fsb and vcore ill let you know
thx man

 

Small increments.... You want to keep it stable

 

IS YOUR PC OC WHAT NUMBERS ARE YOU USING?
AND WHAT COOLER YOU HAVE?

 

I don't understand what you are trying to ask about OC speeds. The cooling system I use is the Cooler Master Jet 7+ heatsink and fan.

 

im talk fsb,multp you are using i belive you have and xp 2800+
