EIST & Turbo Boost help

[PaulC2K]

Hi,

I recently purchase an i5 2500k having had a Q6600, and im hoping to get just as much value for money and amazing performance from this CPU as i did the last.
Previously i had my Q6600 running at a mild 3ghz, and had EIST running and it'd go down to 2ghz or thereabouts when it idle. I see EIST is available on my mobo (see sig) and yet despite it being activated in the bios it doesnt appear to be running.

CPU-Z and Core Temp both have it running at 4ghz which is what its set at *at the moment* (mainly to see if that would see EIST drop to 3.3ghz or something). Theres 0-1% load, so obviously the ideal time to wind down the settings and run cool and thus near silent.
Is there something new which may be auto-enabled which is negating the ability for SpeedStep to run? Ideally i'd love to see it drop as low as it possibly can do as the system is on 24/7 and the requirement for 100% juice is minimal.

Similar sort of question relating to Turbo Boost, i believe this is the anti-EIST, providing more power when more is called for? Its enabled, but doing nothing.

What im seeing while gaming is a default clock setting which takes a hammering sometimes and doesnt do anything, and when im browsing and its twiddling its thumbs, its still powering away at the default clock.
Im monitoring using MSI Afterburner, GPU-Z, CPU-Z, Core Temp, and all the OSD, 2nd monitor and G15 apps so im well aware of my hardwares live status, and its not changing based on whats put infront of it, and im puzzled as to why this might be.

Any thoughts/suggestions would be appreciated.

Nobody is able to offer any advice??

I'm not really intricate with your board but it should, out of the box, work as you expect.

How have you applied your overclock? It should drop the multi/voltage RIGHT down to ~1.6GHz/1.0Volt

All you should have to do is ramp up what multi you want to apply at full TurboBoost and adjust the relevant voltage settings. Auto voltages and some other related tweaks for more aggressive adjustment is usually all that is required to get 4-4.5GHz.

Its just a multiplier increase, so x40 rather than x33. No more, no less.

How im best setting my system up im not sure, but what i'd like it to do is basically alternate between a high clock when needed and a low clock when idle. SpeedStep used to provide the idle aspect just fine on my Q6600 P35 board, and i expected it to function straight out of the box in the same way, preferably somewhere in the 2ghz region would be ideal. Turbo Boost i know nothing of really, but i expected it to do the opposite of what EIST would do.

Right now im using MSI's 'control center' to adjust the ratio on the fly, its been on x20 all day, even with about 4hrs of Dead Island (2ghz & 4ghz made no difference). I've only just enabled this as a short term solution of having 99% low clock, but having the potential available when called for. My understanding is EIST & Turbo Boost should be performing these functions for me, so i get only what i need.

I only ever have speedstep and no other power saving features on, have you tried adjusting the minimum processor speed in windows 7 advanced power features settings.

 

[PaulC2K]

I hadnt thought of the power options, but its currently set as Min 5%, Cooling Active, Max 100%

Im about to reboot anyway, so i might just reset the bios, check those 2 features are enabled, and see if i've somehow changed something (only thing ive done is to enable Virtualisation).

wow, rebooting is slow these days isnt it

Got very distracted, was installing a 128gb M4 i'd just got that morning, reset the bios to default settings, installed W7, typical drivers, and then CPU-Z & Core Temp and had very entertaining results.
Core Temp loaded up first, with an outstanding overclock of just over 10Ghz!! 300x34 The stories of it overclocking well were true
CPU-Z confirmed it was really running 3.4 , CT must have just somehow got the 100mhz steps wrong, but it amused me for some time anyway

It does appear to be moderating the clock though, although it seems to be 1.6ghz or 3.3ghz, no moderation in between, but i can live with that. Hopefully Turbo Boost will work the same when called upon. Cant understand what was stopping it doing this previously though, but all is well for now

if the 2500k is anything like the 2600k then it should down clock to 1.6ghz (16*100) if you vcore is on auto the vcore will also drop to 1 or lower. If you manually set your vcore the multiplier should still decrease but your vcore will stay the same.

My msi does not have an eist option and still does as it is should, try enabling c states and set the power management to intel rather than msi.

Also if you have set your power management options to performance in windows it overrides any motherboard settings and will always run at full pelt. Keep it on balanced.
