ASUS P8B75-V, Intel i7-4770K with 32GB RAM at 2800Mhz
Hello there
I own an ASUS P8B75-V equipped with an i5-3470 and two Kingston 4GB RAM sticks (typical retail specs around 1600Mhz). It comes with an EVGA 500W power supply and a GT 740 SC 4GB GPU. It’s not the most powerful card, but it functions adequately for my needs. Since I don’t play many new games, my system tends to run slower, especially with RAM—sometimes reaching up to 80% usage when several applications are open (especially background graphics apps).
I’m considering a upgrade to 32GB RAM (four 8GB modules) and an i7-3770K processor. This motherboard supports up to 3770K and has 32GB RAM slots, which fits my requirements.
Regarding the CPU, even at its maximum clock speed of 3.20GHz, it reaches 3.6GHz thanks to the case’s multiple fans. The official specs say it can handle up to 2200Mhz in overclocking mode, while the BIOS claims support for 2800Mhz RAM. I’ve looked at several RAM options and found a few that match the higher end, but they’re more expensive here in Brazil. I’m not sure if I should go with the official recommendation or stick to what the BIOS suggests.
For the GPU, the case is a CM 690 II with an HDD dock at the top. With four RAM modules and fans included in some kits, I need a cooler that won’t interfere with future upgrades. The GT 740 SC is compact, but since I plan to upgrade my GPU later, I don’t want a large cooler that could affect both RAM and GPU installation.
My power supply is currently 500W. I’m wondering if it can handle the additional load after the upgrade. If I decide to add a new GPU, should I consider a 650W or even a 500W PSU? Or perhaps chain multiple 500W units together? I saw some discussions about daisy-chaining PSUs in the past.
What should I prioritize—checking the official manual or relying on the BIOS guidance?
