i7-2700k set for 4.8ghz turbo..going 1.6-3.5 in game

post #1 of 19
Thread Starter 
I'm using the UEFI Bios and have the settings for turbo boost to be enabled. I also have speed step on. During random operations on my computer, I've seen the Intel Boost Monitor read 4.8ghz so I know the CPU is hitting it. But when I monitor the speed in Fallout 3, it's going anywhere from it's eco-friendly idle speed of 1.6ghz and speed stepping (I guess) to the stock 3.5ghz. I'm fresh out of ideas on this one...

UPDATE: RealTemp was resetting my CPU to factory clock. From now on I recommend using Speedfan to control temps and MSI Afterburner/HWinfo64 to monitor your temps. I'm not knocking realtemp, it was great for a long time and I love the autoshutdown feature but it was messing me up in the end. Thanks all!!! gunner2.gif

There is no performance loss with Intel speedstep. Its just downclocks and lowers voltage when not in use, or when it doesn't need it.




If you must have it off, turn speedstep off along with all c1e power States.

If you are not lossing any performance with all that off vs on I would leave it on for less heat and power savings, Does it do that in any other games or just Fallout 3, cause it could be it only needs 3.5ghz to wet its whistle lol.

These are good things to consider. I'll just leave speedstep on. I'll try another game as well and check that out. What's odd is now I have speedstep off and I'm not hitting past 3.5ghz. It's still idling around 1.6-2.2 like it should when speedstep is on but it's not on. headscratch.gif

I just set the bios to optimized defaults. Tested again with Portal 2 and Fallout 3 and it will only hit 3.5ghz. Doesn't seem right. Why would the processor hit 3.9 (factory turbo boost speed) when running random programs but only hit 3.5ghz during a grueling gaming session?

does it do the same thing when you run IBT or Prime95?

If i actually had any real experience with SB i would be able to help more but other then what Ive learned from digging through the threads since SB busted out the doors.

Isnt Turbo boost just for 1 core ?
maybe the games utilize more then one core, so it will only speed up to 3.5Ghz cause i cant do 3.9 and 3.5Ghz.

Im not sure on this but it could be a possibility.

Edit :
Try something like Cinebench and see if the cpu stays at 3.5ghz or gets the turbo boost to 3.9.

OH YEAH, but even with 4 threads loaded it should be at 3.6ghz I think as long as the turbo feature is not allowing it to due to temps.

Check your mobo manufacuer to see if there anything for bios/UEFI updates that has to do with turbo issues.
