What board are you using? nForce2 boards tend not to be stable close to 200FSB unless you completely remove the 133/166 jumper. I couldn't get much past 195FSB on my 8RGA until I did that, and now I'm fine at 220.

Also, Bartons on nForce2 boards don't have access to all multipliers. It's either 12.5x and below or 13x and above, based on the 5th L3 bridge. For some reason Bartons are the only CPUs to act this way, but each person I've seen has had this problem.

Athlon XP 2500 Barton or XP 1700?

So I have been following all the discussions for sometime now and am torn between which processor to go forward with on my new rig.

I have an ABIT NF7-S, and (2) Geil Dual Channel 256mb 3200
I also picked up a Western Digital 120gb 8mb cache drive.

Question is this - I'm looking for the most stable machine. I typically leave my machines running 24/7. Which CPU is going to offer the most stability with the highest performance. I have seen the 1700 being declared stable around 2.4 and the 2500 at about 2.2 or 2.3 - but with the increase in cache - is the Barton going to outperform even if at a lower rate?

Price really isnt a major issue - Newegg has the 1700 for $43 and and the Barton for $90 so the difference is really negligible.

General thoughts are appreciated...
Thanks

If price isn't an issue then go with the Barton.

Will the Barton outperform? Sort answer: Yes.

The Barton gains about 3% per mhz from its cache doubling, for an average of everyday tasks. So let's say you have a Thoroughbred running at 2400mhz. A Barton running at 2200mhz is going to be running at an equivalent of 2800 Thoroughbred mhz.

Keep in mind that this is a very rough comparison and by no means applies to all tasks. Some things, such as games, benefit more from a L2 cache than others, such as number crunching (Folding@Home for instance).

Personally I would go with a Barton.

i have been struggling for the last week or so just trying to get to 200 with bad results. Any FSB over 180 and prime 95 would crap out on the first test. I tried your suggestion and now i am at 200fsb with multiplier at x11 and 1.8Vcore. If i go any higher with the multiplier windows xp will load but them crash. Now i am going to run the 3dmark benches and prime 95 again and see if it holds up or is to good to be true LOL.

thanks for the tip

I have the MSI K7N2-Delta_ILSR as you see in my sig, the NForce2 chipset on it is 400 FSB it is a Ultra 400 NForce2. My mobo has a setting for 400FSB (200in bios) so i can set it at 200 and no even be overclocking the board at all. So far with only the CPU overclocked i am getting 17,045 in 3dmark2001se Here

That seems about right for 3dmark01. I'm gettin 17,234 with my 9700p @ 344/675MHz

These Bartons really push their performance per MHz to the limit, but at 2.4GHz max OC, it's not nearly as fast as my 2100+ tbred b at 2.7GHz.

My 2500+ seems to like 2300MHz (200x11.5) @ 1.65v no problem. Ram timings are 5-3-3-2, but I think they can be lowered more. I use an A7N8X Standard (revision 1.04) with 2x512MB GeIL PC3500 UDL Dual-Channel. It will almost do 2400MHz at 1.75v.

I was able to lower my memory timings to 4-3-2-2 at 2.8 vdimm at 200x11.5 with GeIL ULD PC3500.
