Explaining Intel's Turbo Boost technology | Speeds and Feeds - CNET News

 

This is not entirely true. You can't install the OS Turbo Boost driver for Quad Core. The Quad Cores support Turbo Boost natively, without input from the OS and under different conditions.

"The key to this dramatic claim is a feature called Turbo Boost technology. Basically, if the current application workload isn't keeping all four cores fully busy and pushing right up against the chip's TDP (Thermal Design Power) limit, Turbo Boost can increase the clock speed of each core individually to get more performance out of the chip.

It's easy to see how this works when just one or two cores are being actively used; whatever power the other two or three cores would have consumed can be redirected over to the active cores, allowing them to run at higher speeds."

 

Good Point ekuns. The guide is very general and meant for several Dell Models.

We shouldn't forget to mention BIOS settings either. One of these days someone is going to try a clean install with a system that makes use of the RAID, and if they're not tech-savvy they'll be stuck wondering why they can't see there disks from Windows Install.

 

I have an odd issue that I'm trying to figure out. I've spoken with Dell support to no avail (thus far).

I got an M4500 with 4 GB of ram and bought 8GB off of New Egg (because it was insanely cheaper). Dell has verified that the RAM I bought is compatible.

When I install all 8 gigs in the laptop, it boots into Windows Startup Repair. If I try to boot with a Windows DVD in the drive, it flashes blue and reboots. If I go with either 4 gig stick by itself or with either of the 2 gig sticks, it boots fine. Only if I have both 8 gig sticks in does it fail. Despite the fact that both sticks seemed to work, I tried two new sticks, but to the same effect.

I'm using gskill ram.

I'm on the latest BIOS from Aug 29th. Anyone experienced this, or have any thoughts that might lead to a solution?

 

@mikejcook

8GB of non-Dell RAM will work OK, with all versions of the BIOS.

What is the exact part number of the GSkill RAM you purchased?

 

F3-10600CL9D-8GBSQ

 

Since you replaced the GSkill already, it might be a problem with the CPU.

Try a different brand of RAM? If that fails too, you have a better argument for repair.

 

Hello together,

A few month ago I bought a new M4500 with a I7-820qm. After a few repairs I get a new one with a I7-840qm. The problem with the cpu whining is unsolved.
I have tryed a few thinks to solve this problem. But nothing worked fine. The machine work only fine, if i start the sound recorder from windows. But this is no solution.

After the last warrenty repair. I asked the dell support, how I can disable the C4 state of the CPU. But I don't get an answer.

The CPU whining is pissing me off. My Lenovo T400 with a P8400 don't have this problem. In June I have to buy a hp 4510s with a P7570, now this notebook get the same problem. In some cases i will get cpu whining too.

But the worst notebook with cpu whining is the Dell M4500, you can listen to it the most time. If I take out the batterie and plug on the power supply this sound is mostly quiete. The different whinings sounds came from two location. The main one near by the L-Key the second location is by the hdd led.

I run win 7 64bit prof on the notebook.

Is there solution which works fine? At the moment it don't makes fun to work with it.

Thank you for your help.

 

Apparently Dell agrees that my problem shouldn't be occurring and is sending out a repair technician. Thanks for your thoughts.
