Overclocking

[jeezus]

Has anyone managed to overclock the tytn with pocker hack master or xcpuscalar?

For me hack master freezes the device with every settings and
xcpuscalar only "underclocks". And shows false information about the device being overclocked.

Sorry no help here, its just nice to see a nother person who baught both

Overclocking utilities for the PDA tend to be CPU specific. You'll need a utility that is designed for the Samsung CPU.

[raskal]

But for what overclocking? I am really happy with the current cpu speed

Those progs are supposed to support samsung cpu's.
Not a hundred percent sure about the specifk models,
too lazy to check.

Allthou I remember reading something about samsungs power saving on wm5 resetting the speeds and those two programs developers inadept or unwilling to circumvent that. Im guessing the former. ;)
Since otherwise am betting they would do it.

And yes the speed is great. but overcloking is fun. :)

can someone enlight me on the definition of the "stacked cpu"???
have been surfing the net but didn't found anything...

Thanking the one in advance

Peace

I think it means that the cpu is soldered on the motherboard, you cannot "replace" it like in a normal computer.

Mucha gracias hermano *(pof)

Sounds like you Pof wasn't very sure anybody knows for sure or can someone just confirm this?

Respect

I think it means that the cpu has many layers, so the stuff in the cpu is
stacked. Makes the cpu smaller etc.

I read something about what you say: something about first in last out or vice versa. in layer forms yes.
Something to figure out and post in webopedia or something trackable :D on the net.

Thanks again...

Overclocking works fine for me.

I use xcpuscalar in auto-mode with the current settings :

200 mhz - 0-20%
400 mhz - 20-70%
500 mhz - 70-100%

Have had no problems with it - and the 200 mhz saves battery.

Mind running a few benchmarks? And check the speed from somewhere else
then xcpuscalar, it gives false readings.

[Inc]

I wouldn't have any idea how to do that.

Spb benchmark (free) and TCPMP also shows cpu speed, not sure about how reliably, but I guess more then xcpuscalar.

I would not trust xcpuscalars reading, when I tried it, it did too report 500mhz, but other programs showed 400 and benchmarks for 400 and 500 were the same.

The issue about xcpuscalars false readings has been discussed all over the net.

[reddog]

Under Clocking the unit really does not affect its stability, but really does extended the battery life, I have noticed about 40% increase in the battery life, when running the CPU at 200Mhz. :?

For an indepth article on the cpu in the TyTN that also completely answers your question on stacked cpu's visit:

Has anyone tried PocketHackMaster 4.0 beta?

[goestoeleven]

the beta 4.0 doesn't seem to support overclocking on the TyTN. Allegedly it will on the final version though...

[amf]

Version v4.13.031 of Pocket Hackmaster has been released 12 Nov. 2006. Have anyone tried it? Thanks a lot! :)

[amf]

Never mind. I tried it. Doesn't work. My TyTn needs a soft reset after testing.

[ionide]

What exactly doesn't work, overclocking or underclocking? I don't care much for overclocking, but underclocking to save power would be interesting. :)

[amf]

Both. Speeds above and below 400. Even at 400, it hangs.

Here's some benchmark numbers from my 8525... I'm using XCPUScalar to overclock and benchmarking with SPBBenchmark.

500mhz
MFLOPS 4865
MOPS 1505
MWIPS 9823

400mhz
MFLOPS 4825
MOPS 1528
MWIPS 9710

However, when I go to verify speed in About, the phone is still reporting it is running at 400MHz... Scalar reports it is running at 500MHz. My version of Coreplayer does not have speed indication.

the about will not change... it only reports the hardware, not the actual speed

[lacroixdp]

That's certainly not an impressive jump - I doubt that scalar is actually overclocking the device at all. If someone can think of another program that can overclock I'll get it and bench it.

[Wam7]

XCPUScalar does nothing. I had an email from the developer who says "it does not support Samsung processor". He did not mention if it would.

PHM does not work well either so AFAIK there is nothing out yet that can overclock/underclock the Hermes.

[lacroixdp]

I figured as much, especially with the bench numbers I'm getting back. It's a shame too... the tool offers some other nice things such as CPU load and reset buttons :)

This is a quote from the forums of XCPUscalar.

Location: USA I support some Samsung phones that have Xscale CPU's, not Samsung CPU's. Support for Samsung CPU's is on my to do list.

So everyone quit wasting your money on a product that isn't even designed for your phone! fyi, read the website before you complain.

[rblover69]

i wonder what the threshold for this samsung processor is the 8125s workhorse procesor was good beyond 262 thats literally almost double its power from bat. So im curious to when someone is gnna overclock the samsung processor and to what speeds.

[starkruzr]

Isn't the point of DVS (dynamic voltage scaling) that the machine slows ITSELF down when it detects a low system load? Why should we have to tell it to scale frequencies down?

[Gh0sTly]

Im using the latest Pocket Hackmaster(4.32.050) and I am able to overclock my Hermes(8525) to 430Mhz safely. I havent tried any higher than that, but watching the CPU usage, it went down alot. I am using WM6.1, using a cooked firmware(unsure of what one, it came with the phone.) I am new to the device, and after reading at alot of places that this phone's processor is a 400mhz, but is clocked at 300mhz made me want to get its clock speed to 400mhz. so far, so good. :D

If someone can direct me to a good benchmarking tool, I will be glad to bench this at different speeds.

That cant be right.

[Gh0sTly]

eh, like I said, I read it somewhere. It feels alittle more responsive when its set to 450Mhz. but the bluetooth doesn't like to sync to my headset when its OC'd. Other than that, it seems to be fine.

Again, if someone wants to point me in the right direction for a benchmarking tool, I would gladly bench it and show off the results.
