Zertz Posted September 15, 2009 Posted September 15, 2009 Nothing will be more accurate/informative than a real world experiment from our Zertz :thumbs-up: Totally forgot about you guys, I'll check this out for real tomorrow Share this post Link to post Share on other sites More sharing options...

Zertz Posted September 16, 2009 Posted September 16, 2009 Just for you! Turbo works no matter what the base clock is, the only requirement (on some boards) is that the multiplier is left at Auto Share this post Link to post Share on other sites More sharing options...
glenster Posted September 16, 2009 Posted September 16, 2009 Another consideration for comparison is that the Core i7 960 3.2GHz is due Q4 2009 for $562--see Wikipedia > Nehalem > 45 nm processor architecture. Another site says it's due Oct.18. Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted September 16, 2009 Posted September 16, 2009 (edited) Just for you! PICTURE!!! Turbo works no matter what the base clock is, the only requirement (on some boards) is that the multiplier is left at Auto so it will exhibit it's turbo multi change as long as only one core is utilized and the multi is auto but only in some boards. This turbo function is mighty selectively confusing lol Edited September 16, 2009 by IVIYTH0S Share this post Link to post Share on other sites More sharing options...
Zertz Posted September 16, 2009 Posted September 16, 2009 - SpeedStep (allows CPU to change multiplier and voltage dynamically) must be enabled - C1E (allows CPU to drop multiplier and voltage) can be disabled, although there's no reason to disable it And Turbo... Here's a slide from Intel that should help So when the CPU is idle, C1E will fire and drop to ~1.2 GHz. When it figures out work needs to be done, Turbo comes into play, but there are some conditions. To hit the maximum 27x multi in the screenshot, I had a single Prime95 instance running ==> Lightly threaded and below 95W TDP The biggest limitation is staying below the TDP, hence why a heavily multithreaded load will force Turbo to back down to a 0-2x multiplier increase. I see it as a guaranteed, safe and dynamic overclock that kicks in right when you need it, while also keeping heat in mind. Share this post Link to post Share on other sites More sharing options...
Waco Posted September 16, 2009 Posted September 16, 2009 Turbo works no matter what the base clock is, the only requirement (on some boards) is that the multiplier is left at Auto That seems like it could lead to stability issues on even a relatively modest overclock.

Zertz Posted September 16, 2009 Posted September 16, 2009 That seems like it could lead to stability issues on even a relatively modest overclock. Not if you test how much VCore you need for the max clock it'll hit Anyways, I always disable it when overclocking, but the whole point was that there's no limit. It just works.

Waco Posted September 16, 2009 Posted September 16, 2009 Not if you test how much VCore you need for the max clock it'll hit At that point I'd just shut it off and run that speed 24/7 with C1E and Speedstep enabled. Share this post Link to post Share on other sites More sharing options...

ccokeman Posted September 17, 2009 Posted September 17, 2009 It only will hit those higher speeds on single threaded apps. but still nice clocks Share this post Link to post Share on other sites More sharing options...
