View Full Version : 1800 xp overclock?

01-26-03, 11:34 AM
I've got an 1800 xp @ 1.5Ghz with a Volcano 7 heatsink and fan. Can I overclock this sucker to anything higher? It's running on an Asus A7V-266E mobo.

I ran AsusProbe 2 and these are the temp specs on my system:

CPU temp - 59C
CPU Fan - CPU Fan below threshold
Power Fan - Power Fan below threshold
MB temp - 34C
Chassis Fan - 5113
+12V - 12.767
+5V - 4.945
+3.3V - 3.408
Vcore - 1.856

I'm gonna search and see what I can find on this board but would like to know your results also.

Why is ur vcore so high at default? your temps are pretty high but youve already got the vcore cranked up to the max...you might want to get some better cooling for stability.

Vcor On My 1800+ is running at 1.77 Amd says 1.75 V
I have the 1800+ running at 145 fsb - Xp 2000- default is 133 Fsb
It is also Locked -

Duzmor:D :D

Duz !!

what would you recommend for cooling?

I've got a fan in the front of the case and 2 fans in the back.

Looking at your specs you may run into probs, in fact I know you will. Question, How is your case cooling solution config'd(# of fans)? But for starter'z here'z what I see:

CPU Temp:
Way too high for stock speed. You may want to bring it down a lot before OC'ng - to say approx. 30-45*C.
If you have "Thermal tape" applied between your CPU and Heatsink/fan, change it to Artic Silver or Artic Alumina Thermal paste. As I do not know what your HS/F is comprised of, I still would suggest a high performance one something like Thermalright SLK-800 w/Thermaltake Smart FanII or a Volcano 9 fan for slight OC'ing. But the first combo is better for more hardcore but still inexpensive solution compared to an Alpha or Swiftech.

Mobo Temp:
A little high also, but as you improve your CPU cooling this should go down also. Again how many Case fans do you have installed?
Optimally for OC'ing you should have atleast one intake fan and one exhaust (not including PSU fan). Some ppl run 2xExhuast fans for 1xIntake fan in the 80mm size. *Note: more fans=more noise btw, price you pay for OC'ing. Unless you get into H20 cooling or vapo cooling systems...that's a whole different ball game.

Power Supply:
Your +5v & +3.3v rails look a little odd seems ok. What kind is it?
HERE (http://www.anandtech.com/showdoc.html?i=1774) is a nice "roundup" review on the top PSU'z out, some ppl may beg to differ though. But it gives you an Idea of what to look for in a PSU. Remember your Case fans and HDD'z /CD-ROM'z run off your +12v rail and AMD recommends a PSU wattage rating of 350W+ for chips XP and above. Also your VCore is a little high if you're not already OC'd.

Last but not least, try using this MBM 5 (http://mbm.livewiredev.com/) for an accurate reading of system temps and voltages. But do not run ASUS Probe and this together at the SAME time, they do not play well together. When running both at the same time, readings go wacko, so run either or at any one time but can be installed on the same system - just shutdown one before running the other.

Here is example of how I run my rig (see sig below):
CPU: 33*C @Idle; 37*C full load w/CPU Burn-In.
Mobo: 24*C@Idle; 27*C full load
12v: +12.40v
5v: +5.01v
3v: +3.4v

CPU: 35*C @Idle; 40*C full w/CPU Burn-In
Mobo: 25*C @Idle; 28*C full load
12v: +12.25v
5v: +4.98v
3v: +3.3v

*My Case fans are also cofig'd like so: 3x80mm Intake fans & 2x80mm + 1x90mm exhaust controlled/monitored by Digital Doc 5 - so I stay pretty cool.

Also, since ur using the v7, try putting the probe thingy down closer to the heatsink itself so that the fan will run a little faster and cool ur cpu better.

Which xp 1800 is that, the Tbred or Palomino?

Don't really know..how do I find out?

You'll have to take the hsf and look at the die.

It it's a perfect square box with printing ingraved on it, it's a palomino

It the die is rectangle and there's a black sticker on the bottom with white printing on it, then it's a tbred.
