"Unknown CPU Type" error when booting
Just purchased a AthlonXP 2400+ for an old Soltek SL75KAV motherboard.
Happily running an AthlonXP 1800+ for over a year on this board. This was the last upgrade of CPU this motherboard could handle (as it only has 266 FSB and uses SDRAM). I updated the BIOS before updating the chip as per Soltek's website to allow for 2400+ chip on this M/B. Put the new chip in and after clearing CMOS it boots up noting "Unknown CPU type 1700+". No amount of re-flashing the BIOS both back to previous version and the latest version will get my PC to boot noting that it has the new 2400+ chip in it. M/B has dip switches for multiplier and FSB settings, but as I am not o/c'ing this chip, I don't see why I should play with these? Bought the chip from retailer in an AMD box with AMD fan. Should I take the thing back and get a refund? |

You need to run that at 15 multiplier I believe. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

No. You need to set the multiplier and FSB to equate to the speed you want. -- Abit KT7-Raid (KT133) Tbred B core CPU @2400MHz (24x100FSB) http://mysite.verizon.net/res0exft/cpu.html |

The mutilplier in my manual is maximum 12.5 and the BIOS upgrades have never
noted any new pin selection for upping the multiplier at all. Makes me wonder why they place BIOS upgrades on the web site that say it will allow 2400+ on the motherboard if the mutiplier cannot go high enough. I ended up taking it back for a full refund.

The mutilplier in my manual is maximum 12.5 and the BIOS upgrades have never noted any new pin selection for upping the multiplier at all. So this means your board only supports 4 of the 5 multiplier bits. Common for older boards. The 2400+ uses the 5th bit, so anything that you set is changed by the cpu since it's got the 5th bit (8x) active high. Makes me wonder why they place BIOS upgrades on the web site that say it will allow 2400+ on the motherboard if the mutiplier cannot go high enough. I ended up taking it back for a full refund. Only MB's that properly support all 5 multiplier bits can set the multiplier accurately. See Multiplier Cross Ref. in link below. Also check this out. http://www.beachlink.com/candjac/TbredDecode0.htm#Table Since you've already returned the 2400+, I guess it doesn't much matter, but it will work in your board. You just have to know how to set it up. And the Unknown CPU Type doesn't matter. That's just cosmetic, meaning it doesn't know what it is. Here's what the one in the sig line shows up as. processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 8 model name : Unknown CPU Type stepping : 1 cpu MHz : 2400.188 cache size : 256 KB -- Abit KT7-Raid (KT133) Tbred B core CPU @2400MHz (24x100FSB) http://mysite.verizon.net/res0exft/cpu.html |
