'Laptops w. Intel Series 5 chipset can not take full advantage of fast SSDs'

[Phil]

I haven't been keeping track of this thread. Maybe someone else can fill us in.

The fastest tweak you can apply right now with pretty good results is this:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Processor
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Intelppm

Change on both the "Start" from 3 to 4

Only side effect is the increase of temperatures by 2-3 C


The other tweaks are too many for me to trace, maybe JJB, LOUSYGREATWALLGM and others that tried them will make a single post will all the steps

@Phil

Well I've been waiting on some feedback for my most recent (simplified) list of tweaks before consolidating all the steps in one post. Since I have heard nothing negative so far I guess I will try and put it all together tomorrow.

I am leaning toward posting what I consider the 'conservative' settings that I have been running for 2 days without issues. These settings give me full 4K & 4K/32 speeds all the time, the Seq & 512K R/W numbers are not boosted at idle but with as little as a 1 or 2% CPU load max Seq & 512K speeds are available. I prefer this due to the fact it has little to no impact on idle power draw and little (2-3C) impact on temperatures. I have also confirmend that these settings also work on battery with almost no impact on battery life while doing light browsing, have not tried more demanding tasks on battery though....

I guess I can aslo include notes that explain what settings can get the max performance at idle at the expense of higher temps....

LOL you beat me to the response.

I thought your tweak significantly increased the idle wattage and temps on some peoples machines? Hard to keep track here...

They have to try, results will vary according to the CPU, cooling, etc...

The above tweak turned off the Turbo Boost on my laptop. Is this normal? What can I do to turn the TB back on?

In my laptop Turbo Boost is on all the time (but that's probably because of the BIOS and my low temperatures)
If that affects your performance restore the two registry settings to the default values

Agreed. That's what I'm more concerned of especially on medium to heavy load


Anyway, for those who wasn't able to keep track on JJB's settings, here's it is

JJB's latest settings
High performance (power option)

Proc. performance increase threshold = 30%

proc. perf. decrease threshold = 85%

Proc. perf. decrease policy = Ideal

Proc. idle demote threshold = 85%

Proc idle promote threshold = 95%

Proc. performance core parking overutilization Threshold = 95%

Minimum processor state = 0%

Note: Don't forget to record your default temps (idle, min and max) before applying the new settings to see how much heat will this new settings add on your system.



How to activate the hidden options:
WARNING! backup your registry before proceeding this tweak. (in case you messed up your registry)
Start > type "regedit" > HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet (NOT the ControlSet00x)
Press CTRL + F (a new window will popup) > copy/paste the respective Key Name > click Find. On the right pane, change the Attributes from 1 to 0. Hit CTRL +F again for the next Key Name

12a0ab44-fe28-4fa9-b3bd-4b64f44960a6 - Processor performance decrease threshold

40fbefc7-2e9d-4d25-a185-0cfd8574bac6 - Processor performance decrease policy

Note: Ensure that you are always under the CurrentControlSet and not the ControlSet001 or ControlSet02

just a side note, instead of tweaking the registry, you could run the following commands to enable the needed settings under power management and minimize the risk of fiddling with the registry.

Run those from an elevated command prompt (or a normal one if you have UAC disabled):

• powercfg -attributes SUB_PROCESSOR 06cadf0e-64ed-448a-8927-ce7bf90eb35d -ATTRIB_HIDE
• powercfg -attributes SUB_PROCESSOR 12a0ab44-fe28-4fa9-b3bd-4b64f44960a6 -ATTRIB_HIDE
• powercfg -attributes SUB_PROCESSOR 40fbefc7-2e9d-4d25-a185-0cfd8574bac6 -ATTRIB_HIDE
• powercfg -attributes SUB_PROCESSOR 4b92d758-5a24-4851-a470-815d78aee119 -ATTRIB_HIDE
• powercfg -attributes SUB_PROCESSOR 7b224883-b3cc-4d79-819f-8374152cbe7c -ATTRIB_HIDE
