Upgraded CPU on KT7A problem

Many thanks for that, Wes - no success I'm afraid. Your first suggestion resulted in locking-up and I had to reset the CMOS. The maximum multiplier available in BIOS set-up is 12.5 and above. Using this, I still get the CPU reported as a 1300MHz thunderbird. Thus, I get the same result whether I employ user-defined or not. So, in other words, as long as you keep the FSB at 100, everything works. And anytime you set the fsb to 133 it fails, even if you chonge the multiplier to let's say 9? If that's the case, it's not the cpu. It's more than likely your ram now working at the speeds you have it set for. The ram bus follows the FSB, so when you raise the FSB fromm 100 to 133, the ram bus speed increases to 133 also. And your ram isn't working at that speed. It could just be bad ram that won't operate at 133MHz, but it could also be how you have the ram set up in the dram section of the bios. And it moght be the PSU too. Forgive my ignorance , but I do not understand what you mean by looking at my ram/timings. I've got 768 of 133 RAM. Any other suggestions would be welcome. Pull all the ram except 1 stick. Manually set the ram settings to the slowest, cas 3, 80ns (I think). Now set the cpu multiplier to 9 and the FSB to 133 and see if it works? If not, try a different ram, repeat. I assume there's lots of ram tutorials on the web, try and find one. -- Abit KT7-Raid (KT133) Tbred B core CPU @2400MHz (24x100FSB) http://mysite.verizon.net/res0exft/cpu.htm |

Question, is this Athlon 1400 actually an "Athlon XP 1400"?!
If so, I have a pretty good idea what the problem is. Many people have forgotten at this point, but, the original release of the Abit KT7A *preceeded* the first release of the Athlon XP. As such, many mobo's do NOT (at least not "officially") support the Athlon XP. At this point, I frankly don't recall the technical details (I'm sure an Internet search would turn up something), but it has something to do w/ power-up requirements. Perhaps the original KT7A FAQ (kindly hosted by Sudhian Media, see http://www.sudhian.com/showfaqs.cfm?fid=2 ) can provide more details. That's why when I bought my original KT7A-RAID, around the time of the release of the Athlon XP, I made sure to get a revision 1.3 mobo!, the ONLY version I know of that *is* officially sanctioned as Athlon XP compatible!!! Again, MANY people have forgotten this little detail, and it wouldn't surprise me in the least if this is indeed your problem. As far as my KT7A-RAID v1.3, I've since sold it, but I was running the Athlon XP 2000+ on it at the time. So w/ the right revision, it *will* run Athlon XPs. IOW, the problem is much like the Intel mobo's of today. Everyone is concerned whether they will/do support the new Prescott CPU. It just depends, you have to check w/ your mobo vendor. And like w/ the KT7A and other pre-Athlon XP mobo's, everyone will, one day, forget about this little caveat, and a whole bunch of new users will be puzzled why their heavily discounted Intel Prescott doesn't work on their circa '2003 mobo. Of course, I'm just speculating about your processor, you didn't mention XP specifically, maybe just an oversight, but I don't seem to recall any non-XP Athlons ever being released above 1.33GHz (don't quote me, just don't recall). Seems to me the XPs started w/ 1.4GHz and above. HTH Jim "Rex D Last" wrote in message ... I am new to this newsgroup and apologise if this has been answered in the past. I have just replaced my AMD Athlon 800MHz with an AMD Athlon 1400MHz 133 CPU. I have installed the latest BIOS update for the KT7A MB (7/11/02). If I enter this CPU in BIOS set-up the system locks up and I have to reset the CMOS to get going again. The system runs perfectly well if I set the CPU as 1300MHz but then it is only recognised as a 1300 Thunderbird. Is it possible to get the full performance from this CPU? I am running W98SE. I have also tried manually setting the CPU in BIOS set-up, although I was uncertain of the correct settings and tried several, and changing DRAM CLK to HOST CLK+PCI CLK but the system locks up in the same way. Any help or advice would be welcome. Rex Rex D Last Somerset UK) |
