Hi,

I Have recently got a new cpu ( Socket 7 ). I have had no trouble istalling it, but it is a 500mz cpu, and it is only running at 350 mz, i think it is something to do with the dip switch settings, my old cpu was a 300mz cpu. i tried downloading the manuel for the motherboard, but my computer crashes when ever i try. I have a gigabyte GA-5SMM motherboard, with a 64mb RAM card, and two 32mb RAM cards.

I want to get it running at 500mz, but i dont know how.

Please help.

Since later reported it was "finally working", the following explains the most likely causes for a Socket 7 CPU running slower than expected and gives a concise, safe checklist that others can apply to the same symptom.

Common root causes: incorrect DIP/jumper settings that control FSB or multiplier; a motherboard BIOS that lacks support or correct microcode for the CPU; or a board voltage/jumper mismatch that forces the CPU to run at a safe (lower) clock. A quick rule: CPU clock = FSB x multiplier, so a wrong FSB or multiplier setting will directly change the reported speed.

Troubleshooting checklist:

  1. Identify the exact CPU marking and required FSB/multiplier.
  2. Find the motherboard switch/jumper table — on the manual or printed on the PCB — and note the current switch positions before changing anything.
  3. Set DIP/jumpers to the combination matching the needed FSB or multiplier, then clear CMOS (power down and use the board method) so the change is applied.
  4. Confirm reported speed in the BIOS setup or POST screen. If still incorrect, check whether the board offers a BIOS CPU support list or microcode update.

BIOS and voltage notes: as suggested, a BIOS update is often necessary for newer Steppings. Only flash with the exact vendor file and follow the vendor procedure: backup current BIOS if possible, use a reliable power source, and do not interrupt the flash. Also verify Vcore requirements — some upgrades need a different core voltage or on-board regulator setting; incorrect voltage can cause the board to fall back to a safe clock.

Practical tips: if the manual cannot be downloaded from the problem machine, follow and use another PC or print the manual elsewhere. Keep a written record (or photo) of final DIP/jumper positions and the BIOS revision once resolved; that prevents repeat troubleshooting later.

I don't think anybody can help you without the online manual. Have you tried to access it using a friend's computer? You can also print it wthout downloading it.

Have you tried to update the BIOS, you may need to support the newer processor.
