Barton 2800+...2500+ or keep the 2700+ TB?

Hey everyone...I am kind of a newbie here..been a reader for a month or so and this is my first post. This place is amazing...I did'nt think I was a newbie to the o/c world, but for the last month or so I am learnig that there is alot more to it than I ever thought...got to hand it to you folks here...you guys and gals ROCK!!!!

I just did some upgrading on my rig...new A7V8X-X motherboard...2 sticks of pc 3200 elixer memory....ATX Midtower case with a 400 watt power supply...and a amd 2700+ TB chip was which was supposed to be a barton 2800+ chip.

Which of the three would be my best option...Keep the 2700...Get the barton 2800...or what about the Barton 2500 that I here is a great overclocker? I am going to do some light to moderate overclocking...no water cooling or anything as extrem as that, but stock cooling or maybe some extra air cooling.

Also I read that it would be better to put my 2 sticks of pc 3200 memory in dimms 1 and 3 so I can get dual channel memory. Is this true or what would be my best bet? Does it help with the performance?

Thanks everyone in advance and for making this such a great forum.

as your motherboard will hold u back seeing its only a KT400 motherboard id keep the 2700+ and overclock away if u havent already got the motherboard get a Abit NF7-S

If you can verify the age of the 2800 Barton, get it now. Most, if not all, Bartons and Thoroughbreds with dates after 0343 and some as early as 0335 are multiplier locked and can not be unlocked by any of the old tricks.

Right now I have the 2700 running at 11.5 x 205 + 2325 and my cpu temps are at 34c /35c but I have not pushed the system at all. What multiplier are the 2800 bartons locked at? My 2700 is not locked..I can go up to a multi of 16 with this board. My memory timmings are set at (by spd) is this ok or should I do something different?

A7V8X-X u using that motherboard right ?

how are u using your h/d at 205fsb i sold my A7V8X-X to get a nf7-s coz my h/d and pci slot card wouldnt run at them kind off speeds

205 = 41mhz on pci slots

Sorry...my bad...I have a asus A7N8X-X motherboard...my old board was A7V8X-X.

Did some more playing around and I now have it running at 12.5x200=2405...my voltage is set at 1.80 and my temps are running in the low 30c. I know I should do some stressing on these setting, but what program is good for stress testing?

Do you think I could do better with the 2800 barton?

keep that chip
use prime95 for stess testing lower that multiplier and run the FSB higher dont forget to up the NB chipset voltage to 1.7V

Were do I find the voltage settings for the NB chipset?

O.K. I dropped down to 11.5 x 205 = 2358 and everything seems to be stable...temps are in the lower 30s, but when I run prime 95 I get this....Error: Illegal sumout....just after the program starts. Any idea why or what I am doing wrong? I am using the primenet setting.
