 Posted: Wed Oct 22, 2003 10:08 pm Post subject: P5A won't post at bus speeds > 83MHz |
 |
|
Configuration:
Asus P5A Motherboard rev 1.06 (http://www.asus.com/pub/asus/mb/sock7/ali/p5a/p5a-107.pdf), BIOS version 1011.005 (latest)
AMD K5-2/400 CPU
256MB dual sided PC133 DIMM. 16 chips "MT48LC16M8A2-75C" (http://download.micron.com/pdf/datasheets/dram/sdram/128msdram_f.pdf)
Everything else removed or disconnected.
Problem:
POSTs fine if I set the jumpers to a speed of no higher than 83MHz. Any higher than that - will not POST (on powerup will beep repeatedly every 2/3 of a second).
Please help me figure out what's wrong.
Thanks in advance,
Alex.

How have you set the multiplier-jumpers?
What happens if you set the multiplier lower, let's say 3,0 or 3,5 and with
100MHz bus? Does it work now? |

The multiplier setting does not affect the behaviour.
I tried it with 4, 3 and 2.5 - POSTs with lower bus speed, beeps on higher.

your PSU is verified OK?

well its not 100% guarantee but usually when I can't run the chip at spec or above and I have ruled out memory, its turned out to be
the PSU can't keep up.

Might be a long shot but I haven't read in your posts what you have set
the Vcore at. Also don't know if you have cleared the CMOS(RTC), the
procedure is in the manual but I would add to it, unplug the PC before
beginning.

The chipset is only guaranteed to 66MHz.
I'd take the money and run, myself. That is, leave it at 75Mhz or
83MHz and run it.

k6-2/100mghz run fine at 66mghz, flaky at 75 or 83! |
I ran 350's or 400's at 366(max multiplier).
He's got bad ram or bios set to cas2!!!!!!!!!!!!!!!!
Just cause it worked in another computer don't mean ***!!!!!!!!! |

It's a 200W PSU that was running an Intel Agate board with a P-MMX/200 (@66x3) full of PCI & ISA cards and drives for the last 4-5 years with no problems. For the P5A, I removed all the cards and disconnected all the drives so there should be no excessive power load.
I haven't ruled out the memory yet, it is just not the prime suspect at this time. |

Yep.
I also booted (at lower bus speed), flashed the latest BIOS and told it to load the setup defaults.

No, the chipset supports 100MHz. Says so in the manual.

no no no.... I am not referring to the 12v rail(powers the drives).....but the power circuit to the CPU. 4-5 years pulling that
load....I suspect the PSU..
