1400(133) changing multiplier.

I just checked it out on the Asus website, and that particular board isn't compatible with Thunderbird 1400 C (10.5*133) processors, it only works with the 1400 B (14*100), which is quite weird since it allows to manually raise the FSB to 133 in the BIOS. He may have to set all his memory timings to the absolute minimums to do so though, no Optimal, or turbo mode etc. The problem is the KT133, or in this case the KM133 chipset. Even though the bios of my old KT133 chipset board list FSB speeds all the way up to 147MHz, they didn't work. The KT133A chipset fixed that. I wasn't sure if it was fixed in the KM133 or not. That's why I asked him to try it. Apparently it isn't. Not having tested the upper multipliers of the Thunderbird core cpu, I'm not sure if it has the 5th multiplier bit to allow multipliers up to 24x. It doesn't have an external bridge for the 5th bit like the XP's do but it still may be a valid bit inside the cpu. If it is, then unlocking the cpu and using the pin mod would give him access to all the multipliers up to 24x. Of course 14x is probably as high as he'd want to set it, although uping vcore to 1.85v and 15x might work too, but I think they were pushing the core at 1400MHz even though some have claimed to get over 1500Mhz from an Athlon 1000 tbird. I know I got over 1300 or 1400Mhz easily out of mine, but don't recall which it was and that was on the old Kt133 chipset board limited to about 116MHz FSB. That was over 2 years ago so don't recall specifics. Hi Wes and everyone else who replied, Just to clarify; The FSB control in the bios only goes to 110MHz, it can be jumpered to 133MHz but is only stable at 103MHz maximum. The memory is definitely running at 133MHz and is stable. I'm going to try closing the L1 set with a pencil, but I think I'll have to fill them first, because the cuts/burns look too deep. Can I just use car body filler or something else like that to fill them? You're right Wes, the KM(T)133 chipset was released to run the memory at 133MHz but the FSB was only stable at 100MHz and so the speeds are set separately. The KT133a was the next release with both FSB and memory bus being stable at 133MHz. -- Ian |

What's the part number on the cpu and how many L1 bridges do you see 4 or 5? The 1400 tbird should be a ceramic package and does not cut down through the ceramic material. The part number should start A1400 if it's a tbird, and AX1400 if it's a palomino core XP. On XP's with organic packaging I used super glue to fill the laser cuts. On ceramic parts you should never have to fill anything ever. -- Abit KT7-Raid (KT133) Tbred B core CPU @2400MHz (24x100FSB) My server http://wesnewell.no-ip.com/cpu.php Verizon server http://mysite.verizon.net/res0exft/cpu.htm |
