AG8 and intel 630 CPU
AG8, 3.0 GHz i630 Chip, 1GB Geil DDR500 Ram. Running happily at 3.7 GHz
(247 fsb), Sotck Voltage on everything, BIOS Rev 24 - I've encountered some quirkyness with this board, works the same in the BIOS screen, or uGuru: 1) To overclock, I have to bump my FSB at 5-10 mhz increments at a time. If I do one huge leap, it fails and reverts back to stock. 2) I can't get the memory hub speed (Northbridge?), to lock to the FSB, when the CPU is set to "User Defined" (even if I set it to stock 200... "204")! If I select that option and save, it just goes right back to "800". The memory is indeed running at the correct 1:1 speed though according to CPU-Z and uGuru. 3) I can't change the CPU multiplier (I think the 630 does not have this option anyway, while the 640+ CPUs do?). 4) The FSB:PCIEx speed cannot be changed to anything except "AUTO", so I don't know what it's running at. This may be a side effect of #2 as the PCIex talks directly to the northbridge. 5) Watercooled, my CPU runs at 11c idle and 27c load. Now that's not possible as my room temp is 20c! So if I add say 15c to those for a correction, it's more like 26c idle and 43c load. Abit supposedly fixed a calibration problem with the latest BIOS, but not for my CPU... Really, I can't complain - the system is ROCK solid at 247 FSB. If I go any higher, even 248, it gets flaky. Voltage jumps on CPU/MEM/NB do absolutely nothing! So... I'm wondering if it's something to do with #2 or #4. Anyone dive deep into this thing and have any insights? I still love ABIT! |
