Overclocking the Mogul/Titan 6800

[xweaponx]

In the past 12 hours that I have had HTC Performance, the only real difference I have seen was that it loads from one program to another faster. It doesnt necessarily load the actual program faster persay... such as PocketCM.
PocketCM still takes a half second to load wether you are overclocked or not. But switching from settings to programs in start menu is faster as well as switching between the tabbed menus on my today screen. But accessing the \windows dir still brings up the busy icon and still takes it's sweet time loading as usual.
I am running at 624 for now and have experienced no lock ups, freezing, etc and battery usage appears to be the same. By Wednesday, I will switch it to 520 and give it a 4 day run and post results thereafter.

WTF?!?

Do you guys know what you are dealing with??

THIS APP IS DESIGNED TO WORK WITH INTEL XSCALE CHIPS, not our Qualcomms!

As with all overclocking apps, these things are CPU SPECIFIC.

For those of you unfamiliar with the concept of overclocking:
Modern CPU's are designed to run at different clock speeds. The manufacturer selects a certain clock speed in the factory based on factors such as intended battery life and reliability of the components. However, many of the chip manufacturers design it to accept a special command to change that clock speed at will for testing/debugging/etc. These overclocking applications supercede the operating system and send that machine code command to the chip.

The problem is that EVERY CPU MANUFACTURER HAS DIFFERENT CODES TO DO THIS. For example, when the Intel Xscale chip first came out, there were tons of apps to overclock it, however they only worked on Intel's chips and not on other PPC processors such as Samsung and TI, or even Intel's older StrongARM chips.

Sometimes trying to force this code would confuse the chipset and lock it up, or worse, fry it. Yes, playing with overclockers can fry your chip if it wasn't made for it. The best case scenario here is that will just do nothing. (I've seen many people claim overclocking did "something" to their speed even tho it wouldn't show up in any benchmark tests. Its a total placebo effect)

Back in the days of the HTC Wizard, which ran a TI OMAP CPU, some people tried XcpuScaler (which was for the Xscale chip), only to find it would lock up their device until hard reset. Omap IS overclockable, but you need an Omap-specific overclocker, such as OmapClock.
The same was true of the older ipaqs that used the Samsung chips or even the original ones that had the Intel StrongARM chips.
Yes, I've seen those get fried from people messing with overclocking apps they didn't understand.

BOTTOM LINE:
The titan/vogue use a new chipset by Qualcomm, which is NOT compatible with the Xscale overclock commands that the Apache's chip accepted. In fact, there are many incompatibilities with these 2 chips (just look at the direct draw support).

At the very least, this is just a "sugar pill" solution. Luckily it seems that the Qualcomm 7500 chip is smart enough to just let the command bounce off it instead of locking up like some other manufacturer's chips. However, its still very possible that you're all doing some damage to your processor that we can't see yet.

If someone writes an overclocking app for the Vogue or even the Kaiser which all use new Qualcomm chips, then it will work with our Titans. Until then, I would very highly recommend not to mess with this.

HTC Performance is different - since it does absolutely nothing, it works on all cpu architectures. You'll think it's speeding your machine up no matter what hardware you use.

I don't know guys I have been using for about 3 weeks and when I step it down or disable it the device is slower. I have also had only a couple of lockups (only requiring a soft reset). So far so good for me, has about the same effect as on the 6700. Nothing quantifiable, but it does 'feel' faster in nearly everything...

I am not saying you guys are wrong, simply sharing my experience.

So it does not overclock?
We need some benchmarks. Anyone know of any benchmarking utility?
My friend noticed a considerable difference playing call of duty while overclocking using the HTC performance utility. He said that it was very choppy running at 400mhz and used the htc performance cab, oc'd to 624mhz and increased the fps considerably and made the game noticeably smoother.

Oh I know, I am the OP on the 6700

I did all the benchmark tests. It changes nothing. Nothing measurable. Nada. Zip.

But damn if it doesn't feel faster

you know I used to use a little ap called autostep, it was written for the i730 but worked on early roms for the 6700. Anyway, my point is the ap opened up the processor to stepping up to 520, but most of the time it would still run at lower speeds. it didn't do any of the typical oc'ing tricks like changing voltage or ram ocing (like xcpuscaler and others) so it was never a huge kick, but smoothed things out. I can't help but wonder if this is what's happening here too...

[schettj]

well, you would think a CPU benchmark that pegged the CPU at 100% would run faster if the CPU ran at a higher clock rate even for 5% of the test. Sadly, no such measurable effect is shown with this thing.

It's all in our heads.

[solarbarack]

You got me. I did read your post on the bench marks, but I gotta say it feels a tremendous amount faster.

[nuguy]

It does something, I just can't tell you what exactly...
