I confirm there's no driver for Intel® Turbo Boost Technology, per se, that you can download, as this is a feature of the CPU; see the following URL:
Once you install a compatible Operating System, with the corresponding, latest updates and system device drivers, when needed by the Operating System and/or applications you run, the Intel® Turbo Boost Technology gets into action; see the following URL for more details on this:
Note: There's no driver for Intel® Turbo Boost Technology unless you rather mean Intel® Turbo Boost Technology Monitor. If this is what you mean, then, I regret to confirm Microsoft* Windows* 2008 Server is not a validated operating system for it; see the following URL:
Thank you for the explanation and the links.
The Dell download site for my system had the turbo mode monitoring gadget (for Win7). I don't need the monitoring gadget. So I'm fine skipping it.
However I am still a little fuzzy if I need to do anything to make turbo mode go on my system? The second article you pointed me to states "Intel Turbo Boost Technology is activated when the Operating System (OS) requests the highest processor performance state (P0)."
So in my case will Win Server 2008 R2 SP1 (I had to install the beta SP to get Hyper-V to work without crashing my system) active turbo with the drivers that came with Windows? Or do I need to install something else to make or allow Windows to active turbo boost? Since I don't have the monitor I'm unaware of any way to tell if its kicking in.
Thanks again for your help.

Here is a link for the release notes of the Intel Turbo Boost Technology Driver
*It does not mention any support for server 2008.
Some nice information here about IIPS
and here is a summary from V1 of the i5-520M datasheet
3.4.2 Intel HD Graphics with Dynamic Frequency
Graphics render frequency are selected by the Intel graphics driver dynamically based
on graphics workload demand as permitted by Intel Turbo Boost Technology Driver.
Intel Turbo Boost Technology Driver can optimize both processor and integrated
graphics performance through Intelligent Power Sharing. The processor core die and
the integrated graphics and memory controller core die have an individual TDP limit. If
one component is not consuming enough thermal power to reach its TDP, the other
component can increase its TDP limit and take advantage of the unused thermal power
headroom. For the integrated graphics, this could mean an increase in the render core
frequency (above its rated frequency) and increased graphics performance. In addition,
the processor core can increase its frequency higher than it would without power
Utilization of Graphics Dynamic frequencies require the following:
• Graphics driver
• Intel Turbo Boost Technology Driver
IMO it doesn't seem there is a lot to worry about not using it especially if your going to be running on the discrete GPU except perhaps 3289904. (See release notes).
Finding correct drivers is probably going to be difficult without support from Dell, probably more so for running server 2008. Try installing the OS with it's own native drivers and work from there to find what's missing. Another poster (virtual) is having problems with hyper-v and i5-520M (I think!). Maybe if you get together 2 heads are better than one.
Thanks for that info.
I guess I'll just have to cross my fingers and hope I'm getting the benefit since that driver described in your first link isn't supported for Windows Server 2008 R2 ... although it is supported for Windows7 x64 and I was under the believe that Win7 x64 and Win Svr 2008 R2 shared drivers.
I made a post to virtual suggesting that he install the Windows Server 2008 R2 SP1 beta before enabling Hyper-V. That solved my Hyper-V problem.
I ordered two dell R310 servers with X3450 Lynnfield proc's in them and 2k8R2 wouldn't go past 2.66 GHz (should be 3.2GHz with turbo). I found out that if I put the power plan on "High performance" (in Power Options menu), I could then get Turbo to work. Once I changed the "Minimum processor state" in the sub menu back to the standard setting of 5% (like the "Balanced" is set to), I had Turbo and EIST in use together and idle would run at 1200MHz, while under stress test would go up to 3.2GHz with 2 threads active, 2.8GHz with all 8 active. See if that works for you.....
Also, I didn't load any special driver. The only thing I changed was the settings in the "High performance" power plan.
How are you able to see the clock rates that you report?
There are many programs out there that can monitor real-time proc/core speeds. This is a simple one. I usually get the zip version, so I know what platform I'm using, which also doesn't include the crap like Ask.com toolbar and such.
Use Prime95 to max out your cores/threads. Mobile Core i5's have 2C/4T, so it'll detect and want to run 4 instances. Be prepared for heat!
Depending on how many threads you run, your turbo speed is effected.
