Using Intel Turbo on 1 CPU

Dozyb · 8 Sep 2012 at 17:40

I have the Krypton Z77 Asus OC Bundle with an I5 CPU. At present it is running in default mode.
My FSX is a single core simulator and I consider OC'ing the system as rather wasteful.
Currently the Intel turbo mode goes to 3.6 GHz when required. Can I set the Turbo to 4 GHz on the core 1 only ??.
Would the rest of the settings cope with this ???.
The rig spends a lot of time sleeping as the other half requires some attention too!!!. Will the sleep mode be disabled if a full OC is applied ??

Thanking you in anticipation (archaic English term)

To answer my own foolish blog. After familiarizing myself with the Asus BIOS workings I took a shot at the Overclockers profile 1 in the Advanced Section, Tools. Surprise!,Surprise!. The I5 Intel settings kept idling at 1.6 GHz UNTIL some extra work was supplied!. The system leaped up to 4.4 GHz accompanied by NO noticeable increase in Decibels. The superb PWM fan went from +- 600 rpm to +-1100 rpm ( water cooled H20 system ). The CPU Temp stayed in the 40's. Using my FSX single core program the single core ran at 75% capacity ( was at 99.99% previously ). Idle power +-147 Watts at 1.6 GHz, Max power +-245 Watts at 4.4 GHz. I have not tested the sleep mode yet but expect to find out in the next hour!. To be continued !.

Further Information. The PC went into sleep mode as planned. Bumping the mouse caused start up. Initial concern about the 4.4 GHz startup was allayed by an eventual return to 1.6 GHz. Alternating between Prime95 and Idle mode resulted in 1.6 GHz ~4.4 GHz cycling.
From a view to conserving as much power as possible and also maximizing frame rates for my most-used Sim this setup is most satisfactory. Very little is perfect in this world but may the PC makers,CPU makers, GPU makers and others involved keep up the fantastic work!! . I hail from the era of slide rules and log tables. It is fantastic to see the huge changes during my lifetime. ( I'm still hanging onto a few neurons!! )

I have reverted to the basic configuration as a high percentage of start ups with OC enabled results in failure and system Repair has to be undertaken. Whether it be the SSD, RAM, or other has yet to be resolved !!

Send it back to ocuk! If your using there oc profile and it crashes then its unstable, otherwise why pay for the overclocked bundle?

Alternativly you could post here and see if someone can help with your settings if you dont wanna rma the bundle ofc

Progress so far!

Thanks for your suggestion Steve. I reside on the Isle of Man and the logistics of sending the bundle back are not worth the bother!.
The ocuk settings ran faultlessly once the PC got going and it coped admirably with Prime,etc.So stress testing is unlikely to find the problem.
The PSU can handle 1 kW so no problem there.

I have "reverse engineered" the ocuk settings and have set my own profile at 4 GHz. Let's see how start ups are for now. A minor voltage change may be all that's needed.

Considering the possible software damage that could be caused by a failed win7 bootup I would see to it that no important stuff was installed until the OC was completely tested on REPEATED START CYCLES.

To complete this thread, the PC BIOS and Win7 are looking after the energy saving side and the Intel turbo and overclocking are working when needed. The main problem was a
dyspeptic SSD (new). As the first SSD was occasionally ok I cloned it onto a second new SSD and the OC and OS began to run very well. The suspect SSD is now running fine in a SEDATE laptop under WinXP.
I have also had problems with my latest PC project but patience, etc, fixed it.
Fun!,Fun!!,Fun!!!
