I know this is a stupid question, but what is the FSB for the Athlon XP 2600+. My friend is saying that if he goes above about 174, it won't boot.

Spec:
Intel P4 2.4B
MSI 645E Max-U Mobo
1GB DDR333
R9600XT 128MB
SB Live 5.1
WD 60GB
Maxtor 120GB
LG DVD+-R/RW
WIN2K PRO SP4

Hitting a wall with PC2700 at 174MHz is normal, don't belive the hype and FUD, PC2700 aka DDR333 is made to run on a 166MHz FSB.

DDR stands for Dual Data Rate, meaning it can send twice as much data as PC166 standard SDRAM.

On the other hand, Thoroughbreds and Bartons are known to be able to run on a 200MHz FSB but that requires good cooling, PC3200 memory, a good motherboard with a powerfull chipset and a decent power supply to keep stable voltage.

You may want to start by loosening the memory timings (3-3-3-6 2T instead of 2-2-2-5 1T) but I doubt that a stable 200MHz FSB is possible with PC2700.

Athlon XP-2600+ 2133MHz (133x16.0)
Athlon XP-2600+ 2083MHz (166x12.5)

As you can see, the 2600+ can either be sold as a 133MHz or a 166MHz FSB CPU, I suspect your friend is using one with a 166MHz FSB, otherwise the 133x16 CPU on a 175MHz FSB would have yield a speed over 2.8GHz, no AMD CPU can sustain that speed unless overvolted and cooled by liquid nitrogen. By running the FSB over AMD's specifications, he is OverClocking, a mediocre 100MHz OC that is.

Tnx for the reply. I didn't know for sure if the XP2600 ran on 166 or 200FSB, thats all. I already told him that if he wanted to OC any higher, he would need PC3200 RAM.

the fsb is 166mhz but if you have pc3200 or higher ram you can overclock it. I have a xp-m that's fsb is 133 runnning at 200.

Right now, the system in question has 1GB of DDR333 RAM, and thats likely what holding him back from OCing any further.
