By now you have probably read the countless articles or threads about the CPU scaling patches or the SmartReFlex patch. So the question in everyone’s head is, which one is right for me? Well the answer is not really black or white. It could be either one or none at all. Just don’t install both at the same time! I decided to run a test for myself to see if either choice would work for me. After running two of the four patches I have concluded that for myself, neither is really worth it. That doesn’t mean others shouldn’t try out the patches to see what they like. In the following article, I will provide you with my overall thoughts on the two patches I have installed, along with what problems and upgrades I saw in my Palm Pre’s performance. Hopefully this article will help you make an informed decision.
I just want to stress that the results that I saw in my Palm Pre, does not make it the same for all
First, let’s go over what the differences are in the two patches:
SmartReflex is a technology by TI that’s built into the chipset that dynamically lowers voltage occurred in the website.
CPU scaling, instead, sets the maximum CPU speed to your choice, (500mHz to 600mHz); this will dynamically change the clock speed based on initial load, from 250mHz to 600mHz. When you overclock your CPU to 600mHz you have the possibility to speed up the aging process of your chip.
{I decided to test out both the SmartReflex 500mHz patch and the CPU scaling 500mHz patch. I thought it would be smart not to overwork the chip at the moment seeing as my pre moves pretty fast with either of these patches.}
My process:
First I install the SmartReflex 600mHz patch. I did a complete shutdown along with taking the battery out completely before restarting. Once I got up and running I did not notice any difference in bring up the launcher pages. The launcher pages scrolled and moved in the same speed they had before. After that, I had decided to bring up the apps in which I use daily. I ran the following: messaging, email, phone, web, calendar, agenda, drpodder, preware, quick contacts, photos and navigation. I did notice a small increase in the opening of the applications but nothing to write home about. So I decided to run a test and open each application one after other to see if I could notice an improvement there. I can say that there was an increase in speed on opening an app if you have multiple apps open. I had no problem moving between 15 apps. Performance was better overall on the web also. Some pages loaded faster but that could have been because of my WiFi or EVDO connection rates.
Negative aspects for the SmartReFlex:
For the two days I ran this patch I did have to restart my Pre at least twice due to it freezing in certain spots, which meant taking out the battery and restarting completely. I also noticed when running multiple apps my battery ran down faster then normal, due to the CPU running at 600mHz instead of the stock 500mHz.
Decision for the SmartReFlex:
The conclusion I gathered for the SmartReflex is that with the 600mHz you will see an increase in performance and a small increase in battery life while the pre is not in use. The down side is that the battery will drain faster if your chip is performing at 600mHz. The battery life is really a flip of the coin depending on how you are using your Pre that day.
Next I installed the CPU Scaling 600mHz patch. From the beginning I had problems. I had to reboot my phone at least twice and pull the battery to get my phone reloaded. Upon running the CPU patch I did feel the pre was snappier and I didn’t see any delay. Battery life was a touch better than before. I also noticed that the apps opened up faster and it was easier moving between multiple apps.
Decision for the CPU scaling patch:
Overall, I used the CPU scaling patch for a total of 9 hrs and did not like the way my Pre was handling it. Since I had to perform multiple resets of my Pre, this patch did not seem like the one for me.
If I had to choose a patch, I would say that I preferred the SmartReflex 600mHz to the CPU scaling 600mHz after testing both out. With both patches you should see an increase in battery life while the Pre is in stand-by mode. While using apps and browsing the web speed in the applications will be better however, battery life will decease faster with the chip running at 600mHz. I have decided, after using both patches, my Pre will be sticking to the stock chip speed and scaling, instead of an upgrade. I for one did not notice a big enough speed boost or greater battery life to out-weigh the freezing and resets that occurred with either patch running.
I’ve read some good stuff here. Definitely worth bookmarking for revisiting.
Couldn?t be written any better. Reading this post reminds me of my old room mate! He always kept talking about this. I will forward this article to him. Pretty sure he will have a good read. Thanks for sharing!

Hello,I love reading through your blog, I wanted to leave a little comment to support you and wish you a good continuation. Wishing you the best of luck for all your blogging efforts.
Hey – nice blog, just looking around some blogs, seems a pretty nice platform you are using. I’m currently using WordPress for a few of my sites but looking to change one of them over to a platform similar to yours as a trial run. Anything in particular you would recommend about it?
Crazy things happen when you walk through the park. Keep up the great blog.
Whatever your taste, this is a great story! Bingo!
Apple now has Rhapsody as an app, which is a great start, but it is currently hampered by the inability to store locally on your iPod, and has a dismal 64kbps bit rate. If this changes, then it will somewhat negate this advantage for the Zune, but the 10 songs per month will still be a big plus in Zune Pass’ favor.
Though I would’ve loved it much more if you added a relevant video or at least pictures to back up the explanation, I still thought that your write-up quite helpful. It’s usually hard to make a complicated matter seem very easy. I enjoy your weblog and will sign up to your feed so I will not miss anything. Fantastic content
I wanted to say that it’s nice to know that someone else also mentioned this as I had trouble finding the same info elsewhere. This was the first place that told me the answer. Thanks.
I found this post while surfing the net some random stuff. Thanks for sharing will be sure to follow this blog regularly and will email this post to my friends.

Valuable information and excellent design you got here! I would like to thank you for sharing your thoughts and time into the stuff you post!! Thumbs up
I eat recently started using the blogengine.net and I having some problems here? in your blog you stated that we need to franchise write permissions on the App_Facts folder…unfortunately I don’t agree how to assign it.
I’m running a Abit AN8-Sli Mobo with AMD 64X2 processor and 4 Gig ram. I recently upgraded from XP pro, SP3 to 7 Ultimate (clean install on new hard drive). When attempting to record with line-in, I find that Realtek AC-97 is not seeing any of the sound card jacks. The sound card I’ve been using is the daughter card supplied with the Fatal1ty Mobo. I’ve not had any problems using this mobo and card with XP for three years, now. I updated the drivers from the realtec site to the newest (R248) driver available, as of yesterday. No change. From what I’m reading on-line, this seems to be a major problem with Win7. Are there any good solutions?
Hi webmaster – This is by far the best looking site I’ve seen. It was completely easy to navigate and it was easy to look for the information I needed. Fantastic layout and great content! Every site should have that. Awesome job
That is some inspirational stuff. Never knew that opinions could be this varied. Thanks for all the enthusiasm to offer such helpful information here.
If you don’t mind me asking I just wanted to get the scoop on what is the difference between blogenenigne and wordpress blogs? Is it easier to use or more efficient? I amseeing a lot of blogs powered by this software popping up lately and wondering if it is better or not? Thanks…
Thank you for the sensible critique. Me & my neighbour were preparing to do some research about that. We got a good book on that matter from our local library and most books where not as influensive as your information.
When you’re a real estate agent, you are your own brand. It’s your own reputation, your own name, on the line. And it’s sad that some people don’t seem to care.
Hello,I love reading through your blog, I wanted to leave a little comment to support you and wish you a good continuation. Wishing you the best of luck for all your blogging efforts.
Great blog. I got a lot of effective data. I’ve been watching this technology for awhile. It’s interesting how it keeps changing, yet some of the core factors remain the same.
I can see that you are an expert at your field! I am launching a website soon, and your information will be very useful for me.. Thanks for all your help and wishing you all the success in your business.
I am definitely a violator of many of these rules. I often find myself conflicted when writing a blog post because I see myself writing more than people want to read, but I feel that I have to do the subject matter justice by thoroughly covering it. I feel that by following some of these rules I end up cutting out important aspects to the discussion. I guess you have to find a balance.
So, when I play a DVD I can hear the music track, background noise, etc. but I can not hear what the actors and actresses are saying. It is like I am hearing some soundtracks, but not the actual talking between actors! Please help. This is true for all Dvd’s
I have recently started using the blogengine.net and I having some problems here? in your blog you stated that we need to enable write permissions on the App_Data folder…unfortunately I don’t understand how to enable it.
In consequence of you in regard to another great article. Where else could anyone suffer from that approachable of intelligence in such a holy way of writing? I have a display next week, and I am on the look recompense such information.
Cheers for your quality facts!! Are you on twitter at all? Can give a tweet through my account right now
I love tattoos and don’t for a minute regret having any of them, I’m currently getting a angel tattoo sleeve done down my right arm can’t wait to get it all done! as can only afford smallsessions at a time. My artist is extremly experienced and also extremly expensive but, he’s worth it! by the way could someone direct me to find a good buddha tattoo please.
Lately I have been doing a lot of directory submissions to build up my backlinks. I write an article and then submit it to the following sites for approval: 1. Ezinearticles.com (constanly crawled by google) 2. Goarticles.com (huge site, lots of traffic) 3. Rysite.com (tweets articles + quick indexing) 4. Articlealley.com (easy to submit to) 5. buzzle.com (has a high PR and is very popular) By submitting articles to those sites, i have recieved a lot of traffic. Especially from rysite.com because i get traffic not only from my article, but they tweet it to a following based on your keyword and as a result I get traffic from twitter as well. Hope that helps!
I really like your writing style, its not generic and extremly long and tedious like a lot of blog posts I read, you get to the point and I really enjoy reading your articles! Thanks for sharing..
You may prepare not intended to do so, but I evaluate you possess managed to designate the brilliance of perception that a a mountain of people are in. The sense of unsatisfactory to remedy, but not clever how or where, is something a all of us are going through.
Me and my old china were arguing about an climax comparable to this! Now I skilled in that I was right. lol! Thanks repayment for the data you post.
I am not much of a guy who thinks in so deeply about web design but I think your post had some valid points in it. Like designers are forced to design stuff within the limited code available and not go beyond it, their innovation is somewhat limited but still I think Web Design won’t die! I agree that Amazon and other some big sites won’t have a blog but now a days it’s very important to have some sort of option available so people can quickly communicate their thoughts. I think Amazon if wants to shift it to that, they can get a customized CMS for themselves.
