This socket also introduces a new method of connecting the heat dissipation interface to the chip surface and motherboard. With LGA 775, the heat dissipation interface is connected directly to the motherboard on four points, compared with the two connections of <a href="/wiki/Socket_370" title="Socket 370">Socket 370</a> and the "clamshell" four-point connection of <a href="/wiki/Socket_478" title="Socket 478">Socket 478</a>. This was done to avoid the reputed danger of the heat sinks/fans of pre-built computers falling off in transit. LGA 775 was announced to have better heat dissipation properties than the Socket 478 it was designed to replace, but the Prescott core CPUs (in their early incarnations) ran much hotter than the previous Northwood-core <a href="/wiki/Pentium_4" title="Pentium 4">Pentium 4</a> CPUs, and this initially neutralized the benefits of better heat transfer. However, the later <a href="/wiki/Intel_Core_2" title="Intel Core 2">Core 2</a> processors run at much lower temperatures than the Prescott CPUs they replaced. </p><p>Processors with lower TDP and clock speeds only used Thermal Interface Compound in between the die and the integrated heat spreader (IHS), while processors with higher TDP and clock speeds have the die soldered directly to the IHS, allowing for better heat transfer between the CPU and the integrated heat spreader. </p> <div class="mw-heading mw-heading2"><h2 id="LGA_775_mechanical_load_limits">LGA 775 mechanical load limits</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=LGA_775&action=edit&section=11" title="Edit section: LGA 775 mechanical load limits"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Intel_CPU_Pentium_4_640_Prescott_bottom.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/6/62/Intel_CPU_Pentium_4_640_Prescott_bottom.jpg/250px-Intel_CPU_Pentium_4_640_Prescott_bottom.jpg" decoding="async" width="250" height="166" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/6/62/Intel_CPU_Pentium_4_640_Prescott_bottom.jpg/375px-Intel_CPU_Pentium_4_640_Prescott_bottom.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/6/62/Intel_CPU_Pentium_4_640_Prescott_bottom.jpg/500px-Intel_CPU_Pentium_4_640_Prescott_bottom.jpg 2x" data-file-width="1372" data-file-height="912" /></a><figcaption>The LGA 775 contact points on the underside of a <a href="/wiki/Pentium_4" title="Pentium 4">Pentium 4</a> Prescott <a href="/wiki/Central_processing_unit" title="Central processing unit">CPU</a></figcaption></figure> <p>All LGA 775 processors have the following mechanical maximum load limits which should not be exceeded during heat sink assembly, shipping conditions, or standard use.

Other chipsets have varying levels of CPU support, generally following the release of contemporary CPUs, as LGA 775 CPU support is a complicated mixture of chipset capability, voltage regulator limitations and BIOS support.
