Tweak: Minus eight to ten degrees Celsius per core temperature through software program manager

post #1 of 9
Thread Starter 
I decided to share this tweek with the community after testing it and having it work very well.

I am using Windows 7 Pro X64. I found out that Windows was trying to run all programs using Core #0 (Thread #0) and Core #2 (Thread #2), though Core #0 was the most heavily used and Core #2 less so. Cores #1 and #3 were hardly ever used and just sat there idling.

I had been using Process Lasso (free software) for a number of years on my work laptop which runs on a single core-single thread CPU to improve its responsiveness. It did its work fine, but it had never occurred to me to use it on my gaming rig as well and try to improve system temperature.

So I did some tests and I was very pleasantly suprised. Basically, Process Lasso is a software which allows easy and free-of-hassle program-to-core assignment:



As you can see, I assigned every single process to use ONLY Cores and Threads #1 and #3. Firefox I don't keep running while gaming, so it is assigned to use all four cores. The idea I tested was to forcibly assign basically everything running in the background while gaming to use ONLY Cores and Threads #1 and #3 while the only application that had access to all four cores while gaming was the game I played at the time, i.e. Rome II: Total War.

Both screenshots were taken at the same time of day with the same ambient of 28 C.

Screenshot 1: Background Applications assigned to Cores and Threads #1 and #3 Rome II: TW assigned to all four cores:



Screenshot 2: Windows Default Program Management. All Background Applications as well as Rome II: TW have access to all cores and threads:



After heavy gaming sessions lasting a couple of hours, I have seen Core #0 hit a ridiculous 74 C without Lasso Program Management on. With Lasso program management on, the same Core would reach at most 63 C.

(Please note: The CPU TIN sensor Max Temperature is incorrect in both screenies).

In addition to lowering individual core temperature by up to 12 degrees Celsius, this tweak has got the added benefit of slightly lowering GPU temperature as well (by up to a couple of degrees Celsius) as well as HDD and mobo temps.

Performance also seems to be better with the tweak on (game seems snappier).

In case anyone's interested, gaming sessions were with Rome II:TW@1920X1080 using the foll. setiings:



Hope ppl find this useful.

Hmm it really looks useful but we need more statistics across different setups. I would like to see whether it improves in mine as I have my cpu under water biggrin.gif

Yeah, I forgot to say my rig is air cooled. I imagine there's probably less value for WC rigs. Why don't you try it and let us know how it went.

Repped for an awesome idea.

My 3930k has one hot core that I would like to assign to light tasks only.

This screenie was taken just now after about one hour RomeII: TW gameplay.

A further note on process Lasso:

1. Make sure to disable "Pro Balance" and any "restraint" rules right next to each running app. Pro lasso was made for use on low juice laptops which needed a "restraint" app in order to restraint "bad mannered" running apps who have got the bad habit of eating CPU cycles and doing nothing in return.

2. Make sure you enable the "gaming mode" for your game app. It helps.

Process Lasso offers a proprietary 'Gaming mode' algorithm which SAFELY and EFFECTIVELY manages process priorities in a way optimal for full screen games. Furthermore, it temporarily places your PC in the 'High Performance' power scheme.

When in Gaming Mode, Process Lasso optimizes the system for Gaming mode by changing the power scheme in Vista+ and making modifications to the behavior of ProBalance. Remember, further foreground boosting isn't very helpful, so don't try to run your game with a priority higher. Process Lasso has been extensively researched and tested, so its changes are much safer than your own custom tweaks. Also remember that Windows already does foreground boosting of its own. We say this to discourage readers from simply setting their game to a 'High' priority. Doing that would not be helpful, and could cause problems.

The end effect is that your game operates with all the resources your PC has at its disposal. In addition, with ProBalance also continuing to restrain unruly background processes, micro-lags are reduced or eliminated completely.
