Does XMP 1.3 boost performance?

post #1 of 2
Thread Starter 
Is it worth upgrading to RAm that supports XMP 1.3?

From Wikipedia:

SPD Tables
Memory module manufacturers write the SPD information to the EEPROM on the module. Motherboard BIOSes read the SPD information to configure the memory controller... (ie. to set memory timings)

XMP Tables
An Intel-developed SPD extension to encode higher-performance memory timings

Advanced XMP also contains voltage information that the motherboard can use to automatically set memory voltage.

You can see speed/XMP tables with CPU-Z.

There's nothing SPD, XMP, nor advanced XMP can do that you can't do for yourself in the BIOS. It's just "Automatic" overclocking. Note, that with manually setting timings and voltages it may be possible to extract better performance than with "Automatic" overclocking.
