| 229203 | 2004-04-14 07:02:00 | As per the discussion in this thread (pressf1.pcworld.co.nz), I've started a new one to make things a bit clearer and then you don't have to wade through heaps of posts. My Motherboard (www.chaintech.com.tw) supports up to AMD 2600+ with bios upgrade (www.chaintech.com.tw) (which I have already done). I've just put in my new AMD XP2400+ cpu which finally arrived :D Anyway everything boots up fine, temps running at 35 oC with stock HSF and some Artic Silver 3 instead of the thermal pad which I removed. In the BIOS it shows my CPU only as a 1800+ and I know for sure its a 2400+. In windows Sisoft Sandra reports it running at only 1500Mhz. I have a hunch that the motherboard is only running at 100Mhz FSB where it should be running at 133Mhz to equal: 15x multi x 133Mhz = 1995Mhz = 2400+ currently it must be doing 15x multi x 100Mhz = 1500Mhz = ~1800+ The Motherboard FAQ (www.chaintech.com.tw) states a similiar problem, and to resolve it was to put the jumper setting for JPX1 (CPU bus frequency) to pins 2-3 (133Mhz). The motherboard manual confirms this with diagram and pics. Yah and when I was putting the cpu in, I'm pretty sure it was set to pins 2-3. I could try the other pins, incase the MB is round the wrong way or something crazy? Am I missing something in the BIOS somewhere? I noticed a new option to increase the DRAM clock speed from 100Mhz to 133Mhz, so I did that. The only other thing I can think of is the CPU/PCI host clock. And that goes up to a max of 115/45 Mhz. I tried that option and windows loads up, but then freezes at the very end of booting. So obviously that is unstable because the PCI is at 45Mhz?? :rolleyes: Gosh, anyone got any ideas for me? :) I want this thing up to 2400+! Thanks in advance! :) |

CPU detected as 2400+ and running at 2Ghz! :D :D Man they must have been smoking some Opium when they wrote the MB manual, becuase its officially in the 100Mhz position. But not according to the hardware, which is at 133Mhz. Thanks robsonde :D |

| 229207 | 2004-04-14 08:34:00 | Manual? Pfft, when i got mine I had to update it three times, reformat the hard drive twice and attemp a windows installation another 3 times.... when the book says It'll work straight away! | Growly (6) | ||
| 229208 | 2004-04-14 09:06:00 | lol! So anyway now my cpu is running at 2Ghz (2400+) The ram is running at 133Mhz (up from 100Mhz) And the FSB according to Sisoft Sandra is running at 2x134Mhz = 268Mhz data rate (68Mhz better than it was before). So in short, double cpu speed~, and 33%~ increase in ram and FSB speed! What more can you ask for? A worthy upgrade for $120. :D Hey thanks guys for all your input and stuff in the threads, much appreciated! |
