I can't help to notice either that not too many people utilizing a good chipset to higher OC. Especially a chipset easily known for 500FSB/2000HT.
For those asking about EIST, do know the differences 1st and then decide wich feels better.
EIST and TM1/2 are both thermal monitoring functions to save power by reducing both vcore and multi.
EIST is the Intel branded method that controls the sped steps from the mobo chipset so it of corse is the least favorable and slowest since it also uses system resorces. EIST must see VID and FID from TM table on CPU die and work in supportied BIOS'. EIST will control what is known as the CPU P state in steps of 1 at a time (ie: your CPU highest of 10, then 9, 8, 7, and finally 6). User will feel this change a bit more since it is using RAM, FSB and CPU as the info is constantly sent back n forth the PC system bus, so it has a slight lag sometimes, and thus will make higher overclocks become much more unstable.
TM2+C1E is another Intel feature but it is on die so the transitions between stepoing is much faster and almost unnoticed by user. TM2 uses the on die VID and FID (vcore + multi ratio) to instantly switch from high to low. In most cases, an average user will not have time to see, let alone use an inbetween multi like 7 or 8 and this change just takes up more time. So TM2 drops to the lowest every time CPU calls for a P state. Now normally that is the moment you do anything in OS, adn is no longer energy saving if it is alwayy on high, so C1E uilizes those tables from TM and allows CPU to function up to certain % usages before calling for a P stare (hault) so a light duty app like media player or surfing the net can work on the low VID/FID. However, at above a certain stress level, C state calls for loading and CPU goes to full multi/and vcore for max power. This is what is called C State + P state.
Now not all motherboards fully function in this C=P State and I do believe Gigabyte is one, wel mine never did. You can however, Endble TM2 = C1E and at least get multi control for reduced clock and save on a bit of heat for high OC. vocre will remain full as set because this mobo is fixed to older tech TM1 not 2, so it doesnt read the VID table to reduce vores along multi. It may be a good thing on some not so stable mobos and or CPUs' since the low VID may be too low for certain OCs'. This was a big issues with old E6600's.
So, even when you have the choice of both at such the mild overclocks I see here a lot, use one or the other, but not both of EIST and TM2+C1E. I'd higly suggest TM2+C1E instead for better stability when overclocking.
Hope This Helps!
