Is it possible to undervolt the Exynos processor? If so, what sort of numbers are people seeing?
Not all processors are created equal. Im using zedomax's kernel V4.1 with Tegrak Overclock Ultimate. The voltage table I have been using without any stability issues are as follows.
1600 Mhz 1000 mV
1504 Mhz 975 mV
1400 Mhz 950 mV
1200 Mhz 925 mV
1000 Mhz 875 mV
900 Mhz 825 mV
800 Mhz 800 mV
600 Mhz 775 mV
500 Mhz 775 mV
400 Mhz 750 mV
200 Mhz 750 mV
Nice table. Any idea on what battery life/performance effects are seen with various voltage/mhz combos?

Thanks for the response. Noticeable improvement in heat/battery?
great battery life. The phone still gets hot but not nearly as fast as it did before undervolting.
Was wondering what the default voltages for the GN are.
350 700 920 1000 1200 1350
1025 1203 1317 1324 1388 1477
I am going back to Thailand next year. I will get this Galaxy note 2 unlock and take it with me.
However, in my country has 3G on 2100 MHz with 3 main carries as follow.
3G
Carries name Band
AIS 1950 MHz - 1965 MHz and 2140 MHz - 2155 MHz
TRUE 1935 MHz - 1950 MHz and 2125 MHz - 2140 MHz
DTAC 1920 MHz - 1935 MHz and 2110 MHz - 2135 MHz
I was trying to understand what it says on box of Tmobile Note 2.
GSM Quad-band: 850/900/1800/1900 MHz UMTS: Band I ,band II, Band IV (Dual-band1700/2100 MHz), Band V
I don't get it much and I am not 100% sure that the phone does support 3G in my country.
Please some experts in here could help me confirm this. Would you please answer this for me? I appreciate every reply and thank you for your time.

For me, I will call TMO tech support to make sure.

I am pretty bad at listening and speaking English. I am Thai. I would love to do so.

I think you should be good to go... The International variant has fewer bands then we do on our T-mobile device so I wouldn't expect that you would have any troubles...:fingers-crossed:
A quick search reveals the following frequency bands in use in Thailand:
•AIS:
GSM 900, GSM 1800, UMTS 900 [VIII]
•TOT3G:
GSM1900, UMTS 2100
•DTAC:
GSM 1800, UMTS 850 [V]
•TrueMove:
GSM 1800, UMTS 850 [V]
The T-mobile Galaxy Note 2 supports the following frequency bands:
HSDPA: 850 [V], 1700/2100 [IV], 1900 [II], 2100
GSM: 850, 900, 1800, 1900
Judging by this, it seems like your best bet is TOT3G, DTAC, and TrueMove for UMTS functionality. All three of these have frequency bands supported by the Galaxy Note 2.

That's old information. These frequencies were used temporary.
They just auctioned the frequencies for 3G in Thailand. The auction is approved by Thai government. I have described the range of frequencies at the first post. But I am not sure it is in 2100 MHz. Any idea?
Thank you for reply.

North America:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/1700/2100 (AWS) MHz (Bands: 1/2/4/5/8)
LTE: 700/750/850/1700/1800/1900/2100 MHZ (Bands: 1/2/3/4/5/13/17)
Europe:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/1700/2100 (AWS) MHz (Bands: 1/2/4/5/8)
LTE: 800/850/1700/1800/1900/2100/2600 MHz (Bands: 1/2/3/4/5/7/20)
two version support different LTE band
Are they using the same hardware?
or only have different software?
Actually the 4G+ work with this agregation (France) :
800 / 1800 MHz > Not used for MM3 (Samsung)
800 / 2600 MHz > Not used for MM3
1800 / 2600 MHz > Actual 4G+ MM3
Is possible to have 4G+ with 800/1800MHz or 800/2600MHz ?
