Hehehe, cool    If you were planning on o-clocking you shoulda got the XP2500mobile.  I am very temted to do this they o-clock to silly speeds with little rise in temp due to the lower voltage required.  Nice o-clock though and a good gain in your scores.  I should put my back to stock and see how much a difference it makes with my raised FSB and tighter timings.

Maybe i should get rivatuner and have a bash at o-clocking my old GF4 ti4600 but i dont wanna blow it up b4 my new card arrives.

I don't really know what effect raising the AGP bus has on the Video Card clocks, only that Aida32 doesn't show it at all, it simply stays the same according to Aida's sensors. I edged it up very slowly in small increments to over 80 in the end with no instability, and only a small performance gain.
The info I read about it was outdated, so I got anxious and went for it.  

Oh! Now you tell me about the Mobile CPU's!

I was beginning to suspect this was why my favorite supplier started stocking them!

I only just found out my CPU multiplier is locked @ 12.5x the other day, and today found out that this condition is permanent.

------------

The CPU I bought is a Thorton core .... ie. a newer Athlon XP 2800+ "Barton" with the locked multiplier, I believe it is a week42, 2003 production model, but my data is not 100% accurate, and I'm not going to pull the heatsink off to get the ID. (I did this on my last cpu and it never ran as cool again!) I didn't bother to write down the ID as I had no idea they were locked at all when I installed it. The last unlocked Barton Desktop CPU's were made in week41 of 2003 according to my sources.

Ok, I could use some help now. Obviously I need to overclock the FSB. My current BIOS allows 1mhz increments on the FSB, but auto clocks the RAM. (not the RAM timings though, unless I allow it.)

Now, the RAM clocks along fine, the same as the FSB speed until it hits 183mhz, (hence my 364mhz DDR bus speed above) when a curious thing happens. The Ram clocks back to a percentage of it's original PC2700 rating or 166mhz bus speed.

In other words, if I set my FSB to 200mhz, my ram then clocks back at 166mhz and I can tighten up the timings again.
If I set the FSB to 190mhz, the RAM clocks back to 154mhz.

Is this controlled by my BIOS or is it the SPD module on my ram chip? Mind you, I was very surprised I could get my budget Kingston Ram up to 182mhz (364mhz DDR!) before it retro clocked on me!

I have some PC3200 RAM to play with out of the P4 in the other room, so that will be the next experiment I guess.

But, I digress.  I hit a wall as I closely approach 400mhz FSB speed, It appears as if WinXP doesn't like it and I only got the op sys up once at 400mhz. (I then ran SiSoftSandra's CPU benchmark and it gave me a "P" rating of 3500+   ). Also, as with the RAM, above 182mhz FSB speed, my BIOS doesn't identify my CPU as an "XPxxxx+" anymore, but simply states Athlon and the clock speed (2.5ghz at 200mhz).

I didn't see any significant CPU heat rise in either BIOS monitoring or Software monitoring in windows, Even while playing FS9. Nor is there any instability as long as my RAM timings are no tighter than 6-3-3-2.5(cas). I tried that timing and 7-3-3-2.5 in benchmarks and saw little or no difference in performance.

Just out of interest, At a stable 364mhz FSB speed, My CPU passes math and multimedia benchmarks well in excess of XP 3200+ levels, However, My overall memory bandwidth is very close to the XP3200+ mark.

I had to buy a CPU for my daughter, it was going to be a Barton XP 2500+, but I gave her my XP 2600+ and bought this 2800 for myself, It has exactly the same standard clocking as my old 2600+, but not as much heat or noise. I was hoping the extra L2 cache would improve FS9, and I secretly thought about the overclocking possibilities. I think I might like it.

I wonder how long before I actually blow something up......  Hope to be back soon   8) (those are safety goggles!)

I made a new case out of some Acrylic scraps in the garage.

Had a go with Rivatuner but I dont think my g/card clocks well so set it back to normal.

I dont gain as much as you have from normal to o-clock system but maybe its down to my g/card???

Unclocked = 11940
O-clocked = 12732

Just wish I could hit 13000 as I am not that far away, just dont think its possible with my current components.

Still you got nice scores    after reading what you were doing and knowing that i got a 6800Ultra on order I thought I would try o-clock my g/card. 

Was risky as my card tends to run a smidge hot anyhow and like you I thought I had lost it    Screen went crazy colours with lines shooting around everywhere looked quite pretty. My g/friend was like oh oh what u done 

I did a reset and its was still like it, I was a little worried then but didn't let on to her and just calmly pushed the power button and said 'ah its just needs to cool down'  Left it 2mins turned it back on and it was workin, wuickly set it back to default clock speeds b4 it went crazy on me again hehehe.

Still its all good fun    If you can get better performance for free then its gotta be done 

Cant wait till my new g/card arrives, wonder what my scores will be hehehe, 3dMark01 20000? I know 3dMark03 should be 12500-13000 

FS9 with everything maxed out totally 1600x1200 4xAA and 16xAF 30fps no lower here I come, well least I hope 

Yes Congo will keep the ti4600 as a spare.  Its been a good card and still holds its own just.  But as the 6800Ultras are so new, and there have been a few probs with some of them, it would be silly to get shot of it.

It will probably end up in my g/friends pc as she has a GF3 ti200 64ddr in there at the moment.  The GF3 will be back up for either PC.  But I wont put the GF4 in hers until I am sure my 6800 is ok
