What the Pentium 4 HT 541 is

The Intel Pentium 4 HT 541 is a 3.2 GHz single-core desktop processor from June 2005. It runs one NetBurst core at 3.2 GHz with Hyper-Threading, so 1 core gives 2 threads. Cache is 1 MB of L2 on a 90 nm process. Power is rated at 84 W on LGA 775.

The 541 served upper mainstream LGA 775 towers on an 800 MT/s bus with a 16x multiplier at about 218 dollars launch price. It exists because buyers wanted Hyper-Threading at 3.2 GHz with 1 MB of cache below the 115 W 550 line.

Socket and motherboard compatibility

The 541 drops into LGA 775 boards with DDR2 memory and a BIOS that lists Prescott 5xx parts, such as 915 boards. It pairs with mainstream chipsets contemporary with Prescott. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is DDR2 through the board chipset in two channels.

An 800 MT/s front side bus ties the CPU to the chipset. PCIe slots hang off the chipset.

Cooling is any 84 W rated LGA 775 heatsink on the 72 mm mount.

Upgrade paths

On LGA 775 the upgrade is the Pentium 4 HT 551 at 3.4 GHz with Hyper-Threading at 115 W, or the Intel Pentium 4 HT 531 at 3 GHz for a lower cost. Beyond LGA 775 a move to a newer platform needs a new board and memory.

Frequently asked questions
