I just purchased parts via newegg.com for two new systems. I bought the same motherboard for both, with slightly different processor and memory types:
mobo: Shuttle AN35N Ultra (on both)
Proc 1: AMD Athlon XP "Barton" 400Mhz FSB 3000+
Mem 1: Kingston HyperX LL PC3200 1G (2x512)
Proc 2: AMD Athlon XP "Barton" 333Mhz FSB 2600+
Mem 2: Kingston HyperX PC2700 1G (2x512)
I put both systems together, and ran into many problems getting them to POST until I discovered that the CMOS had to be cleared on these boards even on a fresh install. After that, I got a good POST with the BIOS defaults.
On the 2600+ system, I went into BIOS and changed the settings for the processor and memory:
FSB: 166 (was 100)
Mem Speed: Auto (was "by SPD")
CPU Mult: 11.5 (was Auto)
CPU Volt: Auto
Mem Volt: Auto
AGP Volt: Auto
I save the changes, and it does two quick reboots (as it should) and POSTs fine with "AMD Athlon XP 2600+" showing on screen.
As for the 3000+ system, it POSTs when CMOS has been reset, but once I change *anything* in BIOS, it will not POST after saving changes. I've tried setting the proper speeds for the proc and memory at the same time, and individually, and no matter what I change, I get no POST, it just does a repeated beep (one long beep, 6 seconds of silence, repeat).
I have already swapped all the hardware several times, and the problem seems to follow the CPU.
Now, the 2600+ I got was a retail box, and the 3000+ was OEM, with a Thermaltake Silent Boost HSF and Arctic Silver 5 as a thermal compound. Neither system has been run without a HSF, and I can see nothing physically wrong with the CPU.
I'm nearing the end of newegg's excrutiatingly short 7-day OEM CPU return period, so I need to make a decision soon on what to do. All signs seem to point to a bad CPU, but I'd hate to send it back in RMA only to find that I overlooked something simple.
If anyone has any advice, let me know.
BTW, these system boots are all with basic hardware... CPU, video, 1 stick of memory, and a keyboard.
Thanks!
Pat
