SJ30 Overclocking

[isalinas]

Hi!!

Has anybody overclocked his SJ30 with Afterburner, FastCPU or SysInfo?

How much time?

I would like to know if I could break my processor or my PDA overclocking all the time at 54MHz the processor clock.

Thank you by your comments and experiences.

Ivan.

I've used Afterburner and FastCPU. You can overclock all the way up to 54/66MHz depending on the program you use. Read the documentation that comes with FastCPU. It promises that no harm will come to your CPU. However, it cannot guarantee your data so make backups and you should be safe.

[hherbzilla]

I use FastCPU on my SJ30, and overclock apps up to 66MHz. Of course, I'm selective about what apps to overclock. For the majority of progs, it doesn't make any sense to try and run them faser. And I haven't had any problems at all.

[gvtexas]

Ditto. Use FastCPU, but selectively. Helps some programs, others doesn't make much difference.

I just left a post in the Tips and Tricks section about FastCPU and MSImport. Keep MSImport at the standard 33mhz, or it probably will not work.

I keep most of my critical system-level programs at 33 (FileZ, MSGate, MSImport, etc.), but speed up stuff like Handstory, Smartlist, MSDict (BIG improvement), etc. Have these pushed up to 66, and no problems/crashes (yet!).

I can't tell you if running something at 66 on the SJ30 is the same performane as running in native mode on the new SJ33 (which has a 66mhz processor), but I can tell you the speed increase is noticeable, and IMHO, worth it.

But on fastcpu (the new one i guess) the max u can have is 46, how can u go to 66??

[trayip]

Nevermind, found it in options...but isn't that still very dangerous for the device? Wouldn't u like easily fry it or something.

The chances of frying your chip are very slim. Their just isn't enough heat generated to do that. The worst thing that could happen is a hard reset.

I am using FastCPU, but there is no alarm sound if I run 66MHz on DateBook, Agendus, WorldClock, etc., which all are realted to alarm functionality. Is this normal and does anyone else experience the same situation like I do? Thanks!

Not sure about affecting alarms, but I do know that with FastCPU enabled, you do lose some sound events here and there.

Just did a quick test using WorldClock/FastCPU:

33mhz - alarm works
46mhz - alarm works
66mhz - alarm don't-a-work!

So be selective with FastCPU. Why would you want to overclock WorldClock anyway? I have most everything set at 46, a few back at 33 (MSImport will *not* work except at 33!), and some intensive programs like the readers, dictionaries, etc., at 66. Works, but some loss of tapping sounds (like the SJ30 makes a loud sound anyway?)

Hope this helps.

[rprice54]

same here, I can't get any sounds from programs running 66. They work fine though at 55.

Overall I'm happy with fastCPU

[ward0001]

I'm deaf, so the fact that alarms don't work is news to me! :)

[jimroad]

I use Fast CPU where I need it. Large 2mb maps and databases can be swift with Fast CPU. I have t665 which is pretty fast already but overclocking some applications is cool. Try the "find" with Fast CPU running and see what happens.

[RikD]

I use FastCPU and have no problems overclocking to 66Mhz

Although - I do use it more for underclocking and extending my battery life. I have most apps set to 22Mhz, system apps at the normal 33Mhz, and I only overclock apps that are graphic intensive, such as games, pic viewers, etc..

As for the problems with sound disappearing - I suspect it's to do with the speaker interaction being sped up. If you redunce a sound that takes normally 10ms to something that only takes 2ms - you probably won't a) get enough volume, or b) get the right sound..

I keep my brightness on full and FastCPU running hot, and I wonder why I can almost watch the battery graphic slide to the left!

Hadn't thought about the underclocking, which makes sense. I'm sure there are a lot of progs that would run about the same underclocked, and thus reduce juice draw. Will try that...

Gary

[Jeffry]

54Mhz all the way! I'm surprised that the battery life is still GREAT. I love my SJ30.

[cass_m]

I'm still trying out FastCPU set at 46 for most stuff and 33 for all the MS access programs (because herbzilla said so) BAttery life hasn't seemed to change and it's running a lot faster.

I notice a lot of degradation...but come to think of it, I had FastCPU from the beginning, so maybe it's just the Sony battery curse! With my Handera it was unusual to ever see it go down (battery meter)...with the SJ30 it's unusual to ever see it stay fully charged for long! But I do love it...those colors and brightness and small form factor have to be paid for somehow, and if it's shorter battery life, then that's okay...

Damn! Did it again...keep getting knocked off this forum and have to sign back in (which is hard to find!).

i used fastcpu and exchanging data (beaming prc/pdb using beamware and beaming business card) using Irda with my friend's IIIx will sometimes works and other times dont... so i've decided to deactivate it...

any hint what setting should I do for this Irda issue? I have tried to use 33 for all internal apps (datebook, contacts and agendus), but the beaming still most of the times dont work..

any idea?

[vdalian]

if you clock it @ 66mhz how much time can you get out of it with the backlit half way?

[rprice54]

rprice54 here (logged out)

I found out yesterday that I couldn't recieve a beam with FastCPU enabled. I could beam just fine.Tried setting everything at 33 and still couldn't. Something about it being enabled means I can't recieve a beam. (this might explain why I couldn't get omniremote to work)

I'm emailing them about this...

[Jughead]

Hi,

I have an SJ-30 myself and use FastCPU for overclocking. I noticed, however, that I need to deactivate it whenever I need to beam and receive apps, a small inconvenience but an inconvenience nonetheless. Would you guys know if there is a better overclocking software out there? Thanks. :)

Keep rocking,

Edwin

If you intend to overclock a PDA, usually, you will get a 50% to 66% increase in speed. ie. A 33Mhz device will be clocked to 53-56Mhz. Setting FastCPU to 66Mhz will not overclock the device to this rate, programs like speedy and benchmark will indicate that you are still around 53-56Mhz (the real speed).
(Likewise, the T665 at 66Mhz, the highest clocking you can set it to is 100Mhz.)

As for applications to over/under clock - most can be safely done except for the following:
1) Any hotsync related functions.
2) Any beaming functions.
3) Any flash accessing functions.
4) MSImport and any transfer of data between PC and memory stick.

To other queries:
Q. Will overclocking fry my processor.
A. Highly unlikely. Through the many years of overclocking on Palm OS devices, there hasn't been any instances of processors frying from overclocking.

Q. Will underclocking increase my battery duration?
A. Yes. But then again - the backlight is the biggest drain on the system.

I just found that FastCPU v3.0 does not like the Belkin G700 kbd driver. When it's activated the kbd driver does not seem to function on my SJ22.

[AlbertLu]

FastCPU is also not compatible with MS Import on Win2K. Whenever MS Import is activated with FastCPU, Win2K will not be able to detect MS as one of the removable drive. Not confirmed, but this should also affect WinXP.

Personally, feature and option-wise, I find Afterburner better than FastCPU. Plus all the eye-candies on FastCPU means excessive memory baggage compare to Afterburner.

[bluloo]

yeah, I'm a registered user of afterburner too. I just installed it and found no conflicts with the G700 driver. :)

[NJL!2016]

i use fastCPU on my sj-22. when i get up to 66MHz there is no sound. its pretty stable at 55MHz. the increase in performance is amazing. i mostly use it for playing games. one thing it won't do is boost the framerates in kinoma or gmovie

[filber]

I've been trying Fast CPU on my SJ-33, with strange results! When I underclock to the minimum (33 Mhz), all my ROM related apps run superfast! What a hoot! Even a few games, like Insaniquarium and Lemmings, and Low-Res GTS Racing run ridiculously fast. If I attempt to overclock to the max (approx 100 mhz) my Clie crashes and burns. I can overclock to 91 mhz safely. I found that if I underclock everything to 33 mhz but overclock Hi-Res GTS Racing to 91 Mhz, I can run the game smoothly at what must be close to what should be its normal performance...however the shot to my battery (even with the backlight and volume turned WAY down) is devastating. I go from 100% to 30 % in less than 15 minutes!!

I wrote to the developer of Fast CPU and they replied that they are aware of the funkiness of its product on an SJ-33, and are working on developing an update.

[miknitro]

I'll pitch in aswell on this one.
I use FastCPU aswell and find it to be one of the best utility app i have found for my Clie.
No problems overclocking except, like the others ahead of me posted It will not recieve an Ir when overclocked..
So i just deactivate to to do an Ir transfer with a friend then just resume it afterwards.

Not really a problem as i dont Ir alot.

Battery hit is negligible.

that is a pain.:(

[PDA gadgetfreak]

Just started using Fast CPU for my SJ30. No problems that I can see and decent battery life using it. However I don't push all the apps...just key ones.

[mmjoshi]

I have been following this thread for some time now. Decided to do my own research;-) I use FastCPU on my SJ 30. If I overclock it to 66 MHZ there is no alarm sound in World Clock or Agendus. If I overclock these applications to 33 MHZ there is an alarm sound when these applications are running, but no alarm if the PDA is either off or some other applications are running:-(. Finally I found out that if I overclock all applications to 65 MHz everything works fine and the alarm sound is back. There is negligible reduction in performance as indicated by Speedy but that loss is worth it to get the alarm sound back under all conditions. Anybody else had this experience?

[mmjoshi]

It's me again! I do not use MSImport though I have Windows 2000 Professional on my laptop. Any body else like to try this out with Win2K?

mj

[AlbertLu]

Win2K on Desktop and FastCPU at 48MHz on SJ30.

MSImport is totally screwed. ;) No connection...

[Miknitro]

Dang,although mine is a sj22.
I'm running at 50 and no problem on mine at all.
Ms/Import that is.
(and i have read where others had grief with sync'n and import etc,guess i got a tuesday model)
I wonder does the sj30 have a Vz or Ez?
Nitro

[Miknitro]

Doh,theres a difference....may not be the one,but still a difference.

I am using Xp,and have set my transfers on the clie aswell in the hardware setup of xp to transfer at 115Bps,instead of the I was told 57Bps limit.

And,no problems.

Nitro

edit:doh,yes Bps not k,was not paying attention.tks alb.

[AlbertLu]

Hmm... Intedestink idea...

I might cranked up the bps and see if it works on my W2K and SJ30...

[Miknitro]

Let us know if you reach satisfaction or not Albert.


Nitro..

[AlbertLu]

Alas, it is not to be... ;(

I cranked up the transfer bps on my SJ-30 to 115kbps, but apparently there ARE differences between W2K and WXP (which surprises me ;)) - unless I missed something on my W2K, there does not appear to be any option for me to increase the bps for the USB port, which is where my hotsync cable is connected to.

Miknitro, how do you increase the bps on your WXP?

[Miknitro]

Device manager,
Ports(com and lpt)
Com 1 ,port settings.


Hope it helps.

Nitro

Edit ,
As well as in the hotsync setup,right click the icon setup in there.

[na2rboy]

That is for the serial port, not the usb port. You don't need to set the transfer rate for usb, it goes as fast as the hardware allows.

[Miknitro]

True,but unless settings in here match my clie's=no go.
It does effect mine.

Edit,
Note,i use pppgate and this setting effects my Net browsing speed.i switch inbetween hotsync an ppp,sorry i for misleading anyone,but this is how it works on mine.
if the setting is altered,Ie,does not match Clie's,no Browsing.
Yes,am using a Usb con,yes i switch off Hotsync,turn on PPPg and tell Xp i am using Com 1.

I did document this a while back as an unregistered user, at that time i think,Also,if two devices are selected at once=BSOD.
so this is why its not documented to work.
