Fluctuating performance

Terepin · Apr 24, 2012

Ever since I performed wire S-OFF the performance is inadequate at best. I noticed this with LWP, so I tried to run AnTuTu and guess what: it's fluctuating. I ran 4 benchmarks only for GPU. The result were like this:
1. 300
2. 700
3. 1200
4. 500

I even saw CPU working only at 1.2 GHz. I mean, WTF?! I'll make factory reset (again), but I somewhat doubt it will do any good. :-\

I guess you have everything stock. Maybe you should try a different kernel.

I'm not even rooted.

And the point is it wasn't happening before.

I made benchmarks in AnTuTu and Quadrant. This is not the phone I bought.

well if you want to confirm that wire soff is causing this perf fluctuations are not...
flash a revolutionary patched 3.32 firmware from this thread mikes unlocked firmware thread

and chk the performance again

Thanks for the tip, unfortunately I'm on Windows 8, so no go.

Terepin · Apr 26, 2012

Yeah, that didn't help.

I just looked through the guide of the wired S-Off, says you need to be rooted, yet you say you're not?

Terepin · Apr 27, 2012

Not anymore.

Ohh then soff is not causing the issue for you.
I talked with couple of guys about the issue... They are saying that there were some similar issues.. Long back during gb era.. Where the culprit was Nand memory.. Getting screwed

Interesting theory. But I fail to see the connection between NAND and CPU/GPU.

I just had a thought: What if memory was wrongly formatted? Is RUU actually formating internal memory back to it's original file system?

Well memory is involved in all components. It could very well be failing NAND. It's incredibly rare for memory to fail like that, but not impossible.

AFAIK the RUU completely wipes Nand partitions and it does that by formatting them.. And then it feeds those partitions with stock junk... That's why you even lose recovery when you do a ruu run.

But Terepin you can do that again.. Do a format of all partitions and then freshly install a rom.. Either stock or custom..

But if Nand is really screwed then the performance fluctuations really do happen when there are i/o and read/write operations involved.. also the system and data partitions are in Nand.. Which are used almost every time

But my SXE is only 2 weeks old! And it started happening after S-OFF. I don't believe in coincidences.

Terepin · Apr 29, 2012

Isn't there something that can check for errors in NAND?

I seem to have found a problem for you.

Now this is interesting. Even with performance governor the max frequency is jumping from 1.5 to 1.2 GHz. See for yourself.

Thermald kicking in?
