I have a 1 month old GQ laptop RX-7334 which is identical to the ECS G733E laptop. It functions great, but I would like to upgrade the CPU to at least 2,4Ghz. I can not find any help at manufactures websites. The manual states it support 400/533/800Mhz FSB, and give installation details how to insert a new processor, but no info on switch settings/supported processors. Current details: Intel Celeron 1800Mhz CPU System Bus Clock 400Mhz Socket 478 FC External clock 400Mhz Voltage 3,3/2,9V P4N Northwood (0,13mk) Family 15, Model2, Stepping 9 L2 cache 128 Kb Help suggestions appreciated.
