Overclocking Athlon XP 1800+ TBred results

[EglsFly]

I have been experimenting with overclocking over the last day as I have installed a new PC setup:

Asus A7N8X nForce2 motherboard
Corsair XMS DDR400 PC3200 CAS2 512MB ram
Athlon XP 1800+ (Thoroughbred A chip)
eVGA GeForce4 Ti 4600 128MB
Western Digital 80GB 7200RPM ?Special Edition? 8MB Cache hard drive
Enermax 350W PS

I have been able to overclock this Athlon XP 1800+ (1.53GHz) all the way to 1.80GHz, Athlon XP 2200+ speeds!

With the nForce2 board I was able to bump up the multiplier from 11.5x to 12.5x, then I cranked up the FSB to 144, also had to bump the core voltage to 1.55v (from 1.50v).
Memory running in "Sync" mode (288MHz DDR), 4-2-2-2 settings.

Also over-clocked the GeForce4 Ti 4600 from 300/650 (core/mem) to 310/700.

All this netted nice gains in performance:

3DMark2001SE v330 results:
10707 (stock speeds)
12004 (overclocked)

UTBenchmark.exe @ 1024x768:
Stock speeds: Flyby = 140.99 / Botmatch = 55.69
Over-clocked: Flyby = 153.20 / Botmatch = 62.81

Not sure if I should push this 1.53GHz CPU past 1.8GHz?
Anybody else have results of OC'ing this chip? If so, how far did you get it and what settings where used?

1.8Ghz only??

You should try dropping your multiplier, and pushing the FSB up as high as it can go. That way you get more memory bandwidth at the same CPU frequency. For example, your system as a whole will perform better at 10x180 than 12.5x144. With that XMS and an nf2 MB you should have good luck.

Give it a try and see what it does for your benchmarks.

edit: Forgot to add that you can boost your vcore up to 1.80v and vdimm to 2.80 safely to keep things running stable as you OC. Go in increments on the FSB and the vcore.

Boost FSB. Test. If your unstable, boost the vcore and test until stable. Then push the FSB up some more.

Thanks for the advice!

I lowered the multiplier and boosted the FSB.
Got an even better boost in performance!

1810MHz (181FSBx10.0), 512MB DDR362 (4-2-2-2), GF4 Ti 4600 @ 310/700 (v41.09) - Flyby: 166.16 @ 1024x768
1810MHz (181FSBx10.0), 512MB DDR362 (4-2-2-2), GF4 Ti 4600 @ 310/700 (v41.09) - Botmatch: 70.01 @ 1024x768

3DMark2001SE v330 = 13047


Now once I got over 180FSB, going up to 190FSB didn't seem to do much more in regards to performance, seemed to level off.

Then tried upping the multiplier for more CPU speed, but the system wasn't stable.
I cranked the core up to 1.600v and that didn't help any.
Right now the core is at 1.550v.
Should I crank the core up even higher? I only have the retail HSF on the processor.
At 1.550v and 1810MHz, MBM is reporting 44'C (111'F).
What temperature can this CPU handle up to?

You only have the retail hsf!?!?!? Haha, what are your temps like under full load at 1.6v at a stable speed? If its under 55C, I'd say try to go to 1.65v to try to get it stable at the higher speed. The CPU should be good to up around 58C under full load with the retail HSF (anything higher then that and I would have an absolute heart attack, I just don't like temps that high).

nice
keep it going

I bought 5 keyboards because I like to change them every month or so otherwise my fingers get achy and I start to lose my liberachi performance and I can't dazzle my girl with my finger works oh yeah I would leave the fsb at 166 and let the memory run at it too so you are in sync and get rid of that stock HSF then screw with the multiplier a little try to leave the voltage low as possible I can get 1.8 stable out of my Abred 1700 I would think you could better and that was with stock HSF

I recently purchased two 1800xp Tbred "B" cpus and both run flawlessly at XP2400+ speed. My old xp1800 palamino core could only OC to xp2000+ speeds (AGOIA 142 x 11.5).

Both 1800xp Tbred "B" cpus hit 2001MHz (166.81FSB x 12 Mult) at 1.8v.
I know I can get higher but my ram is holding me back.
