I was wondering to hear from anyone that has overclocked their 6700 if there were any ramifications to doing this?
Are there more lockups? Software loading errors?
The reason why I ask is I've overclocked a lot of computers and they are often not stable unless you have extra cooling. That's not possible with a phone. I've already cooked 2 motherboard and CPU's so I'm trying to get more info before I try it.
My device is ALWAYS overclocked to 512mhz. The only ramification is when I am using wifi the unit gets warm and the battery dies quickly. But during regular use without wifi its great.
Funny thing is I cannot get it to overclock to 600 mhz. Everytime I try it locks up the second I click the OK button. Does anyone else have this problem too ? I use Xcpuscalar. I might try the other progam and see if it locks up at 600 mhz with that one too.
Go ahead and overclock. As I said mines always at 512mhz and its fine.
512 IS ALL I GET TOO . but interesting part is when i had the "red sprint logo
the thing would do 728mhz. they def put a cheaper processor in the "yellow logo ones
I have been using XCPUScalar and haven't had a problem with 624 MHz. I normally run the 6700 with a "graduated" overclocking:
0 - 25% CPU = 208 MHz
26 - 50% CPU = 416 MHz
51 - 100% CPU = 624 MHz
But have tried it just set at 624 and still worked fine.
I have a run many a programs with this setting without any lock ups.
I've got mine running at 624 100% of the time with XCPUScalar. I can't even imagine 728, that would be sweet. Any time I try to go above 624 - it locks up.
The only odd thing that happens when overclocking - most people don't even notice. I've pointed it out to a lot of people who used XCPUScalar - so I think it's a universal issue. I wonder if it happens in PocketHackMaster?
Anyway, the only idiosyncrasy seems to be with regards to sound when running at ANY overclocked speed, be it 512 or 624. If you're playing music or a video game - and touch the screen with the stylus, when the stylus touches, the pitch drops and the sound gets really distorted. It can be really distracting when playing a made-for-PDA video game. But that's it. I don't notice it for any other usage, and the only video games I play lately are emulators using the keyboard. Again, the sound only gets F'ed up when touching the screen, and according to Immier, the creator of XCPUScalar - he blames the "interrupt" commands the stylus use sends out.
To me, the issue is relatively minor - and I can't go back to regular speed usage.
I completely gave up on overclocking, the "rewards" just weren't worth the cost in battery life. There are hacks like glymph cache that make more of a difference, with no side effects.
I've said it before, someone needs to write a low-level overclocking program that runs seemlessly. XscaleCntrl used to do this, but it doesn't work on WM5.
"I completely gave up on overclocking, the "rewards" just weren't worth the cost in battery life."
Have you tried the new XCPUScalar version? It includes a hibernate feature so when you're not using the phone actively - the phone's autoscaling takes over. So . . . when the phone's on, but not working for you directly - it'll use up no more power than it did before.
I run at 624 constantly (except when it's hibernating on it's own) - and I easily get through the day using an EBAY cheapie extended battery. I've noticed that if I try to use the program's autoscaling program, I end up wasting MORE battery power. So I recommend running the phone at top speed when overclocking.
aren't all of the chipsets unique? what I mean is I know amplifiers whether for mobile audio or home theater use may be the same make and specifications but that doesn't mean they all fair equally when benchmark tested. I would think our phones are similar?
I used xcpuscalar at 624 no problems at all. And guys stop whinning about battery life with overclocking - we all know the stock battery stinks for run time. I would think most of us that want the speed already use extended batteries. I'm using the 2800mah and I just leave mine overclocked 100% all the time. Have run it that way for about 4 weeks and it still lasts almost 2 days of regular use and easily makes it through the day with heavier use. Shoot with the 3200mah battery even better.
On a related note, someone did some great battery benchmarks on the impact of overclocking and benefit of down scaling a while back. The net result as I recall was that overhead of the scaling pretty much ate up all the benefit from the slower clock speeds. Different overclocking utilities might get different results, but it was enough to tip the scales for me and not bother overclocking/scaling after my last hard reset.
Edit:
Ha, someone else must have remembered it, because there it was when I clicked on page 2:
IIRC, both underclocking and overclocking with either common app utilized more battery power than allowing the processor to run it's native internal routine.

Anyone else noticed their screen kinda very very slightly (only in certainly random areas) jitter? I just installed the XcpuScalar at 520. i think it is faster but i am not 100
% sure. i will know more throughout the day. Cant wait to try this combined with the upx compression to see how much snappier it can get.
I will do more testing but it seems to be only jittery when i have it set to autoscale. When i say jitter i mean a very very very faint flicker.

I've noticed no flickering - but like I posted above, I don't autoscale. I think the only reason to autoscale would be to save battery life - but you won't by using XCPUscalar's autoscaling feature. I believe it conflicts with the phone's native autoscaling to burn MORE power than if you run at max speed. I run at 624 constantly and let the hibernate feature take over - and can get through the day with an EBAY cheapie battery. So I wouldn't recommend autoscaling.
I have read a little bit about people overclocking their 6700. One program seems to keep popping up and that is XCPUScalar. I was thinking about getting this if nothing else for the powersaving functionality. I have a couple of questions. Does this actually benefit from overclocking? If so is it safe to run it at 520(i.e. is it unstable, any heat issues, data corruption, etc.)
I'm using Pocket Hack Master and it works very well for me and is a noticible improvement when running. I'm running it up to 624 or something like that (I don't have my phone by me) but top speed seems to be somewhat random to the specific user's device. PHM has a utility to find what's stable and it's set to scale only within those settings when the bump up in speed is needed. I would imagine XCPU... is similar. I'm using PHM only because I tried it first and it works well for me.
BTW, i'd do a search, this topic has been covered in detail.
I will once again let people know about autostep. Autostep wakes the phone up to 512 and lets the processor take over on scaling.
It is free, has been used a ton on the i730 as well as the 6700. is teeny tiny and I have never had a problem w/ it.
Ok - it only brings you up to 512, and you don't stay there very often, but that's the beauty of it speed when you need it and without any serious battery hit.
Run the install - it automaticly is in your startup folder. It is active with no notice of running.
IMPORTANT - GO INTO AutoStep from start/programs set the processor to 512 click minimize run some aps, check things out be sure it rorks well suspend and wake a time or two.
If that checks out (it will) then go back into autstep and set the wake to 512 - minimize autostep.
Your done.
Always minimize, unless you want to close it and loose the boost. It is so low profile, that you will never know it's there running - unless you close it - and go slow again.
If you feel so inclined, the ap was created by superdave over in the i730 forum here at pdaphonehome.com, he does accept donations through paypal.
