WARNING: Use at your own risk! If you are not sure what you are doing, please find someone who knows how to tweak Windows Vista / Windows 7 settings... so, don't play play loh


Tweaking your Vista / Win7 broadband for UNIFI 5...

SG TCP Optimizer (http://www.speedguide.net/downloads.php) <=download

TCP Windows Auto Tuning = Normal  (I disabled it)
Congestion Control Provider= ctcp
TCP Chimney offload =  enabled
Receive Side Scaling State = enabled
DCA = enabled
NetDMA=enabled
ECN = disabled
Windows Scaling Heuristics=disabled
Checksum offloading = enabled
Tick Window Scaling
Don't tick Timestamps
Set all items in Gaming Tweak to default: n/a.
MTU= 1500 or PPPoE (I use 1480 for local area network card and wireless network)  
TTL=64 

MaxConnectionPerServer =8
MaxConnectionPerserver1_0server=8
Host resolution priority= 4,5,6,7
SynAttackProtocol = enabled
TCPMaxDataRetransmission = 3 (I use 7)
Large System Cache = enabled

Other advanced settings that I use:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
MaxFreeTcbs=65536 (decimal)
GlobalMaxTcpWindowSize=
259200 or 1036800 (You can try other values)(click here to find your value SG TCP Analyzer)
TcpWindowSize=
259200 or 1036800(You can try other values)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{find your network cards for LAN and WIFI}
TCPNoDelay = 1
TcpAckFrequency = 1
TcpDelAckTicks=0




Network card for wireless connection
The “Ad hoc 11n” advanced setting on a device’s wireless adapter lets the device connect to an ad hoc network created on a router using the 802.11n Wi-Fi mode. The advantage of enabling this function is a faster connection when you connect to an ad hoc network. The 802.11n mode can also extend the range of the wireless network, allowing you to connect at greater distances from the router than is possible with an 802.11g or 802.11b connection.

Adhoc 11N = enable
Receive Buffers = 512
Transmit Buffer = 512
Dynamic MIMO Power Save = Disable
Scan Valid Interval=60


Testing my UNIFI 5M on 29 June 2015.

compare i7 3610QM and i7 5500u

Comparison between i7 3610QM (3rd Generation) and i7 5500u (5th Generation)?

I can't believe what I see.... my old Lenovo Y480 which is equipped with i7-3610QM is the winner. hmmmm

That is the reason:  i7 3610QM (4 cores + 4 HTs) and  i7 5500u (2 cores + 2 HTs).







i7 3610QM (4 cores + 4 HTs)
 i7 5500u (2 cores + 2 HTs)

Samsung S6 10 May 2015

Samsung Galaxy S6

I have just bought a new Samsung S6. I still keep my S3 and S4 because I can only get less than RM300 each if I want to trade-in my S3 and S4.

TSL Marketing & Enterprise (U-Mobile) at Ampang Point Mall, Kuala Lumpur.

















In terms of speed, you won't see a lot of differences between S4 and S6 because both have 8 processors. However, S4 and S6 have 2GB and 3GB RAM, respectively.

Since my S4 still uses Android 4.4.2 Kit-Kit, I have noticed that S6 (Android 5.0.2 Lollipop) is more responsive and stable than S4. I really hope Samsung will release an update for S4 in the future.

Now, let us talk about the camera. Amazingly, S6 is able to focus in less than 0.5 second. Wow!!! The photos are as sharp as a DSLR camera.

How about the video? S6 supports VGA, HD, Full HD and 4K videos. Hmmmmm..

In other words, you can leave your DSLRs at home when travelling. Definitely, a DSLR camera can extend its zooming range depending on the lens that you use. You can't do that with S6 or any phones.
























S6 also has a very special shooting mode known as Pro in which you adjust its setting similar to a DSLR camera. Totally awesome!!!

Lenovo Y480 crash problem hang blue screen

Problems with your Lenovo Y480 running Windows 7 Pro 64 bits?

The main culprit is Nvidia VGA Card. After performing the following solutions, my Lenovo Y480 runs very smoothly.

OPTION 1
I just disable 
1) Nvidia GeForce GT640M LE
2) Intel Management Engine Interface

-- Right click the device and choose 'Disable'



















































OPTION 2
You can also uninstall Nvidia drivers (version 340.52 or later) from Control Panel\All Control Panel Items\Programs and Features. Restart your computer.

Then, go to Device Manager and disable 


1) Video Controller (VGA Compatible)
2) Intel Management Engine Interface

-- Right click the device and choose 'Disable'








































OPTION 3
This is the best method in which you totally disable Nvidia.

Go to BIOS settings by pressing F2 when you start your laptop i.e. before you see the logo of the operating system (Windows 7).

Change the graphics from switchable graphics to UMA graphics.

Save the changes and restart your laptop.

Now, you can see that only Intel HD4000 VGA card is available in the Device Manager, and it uses up to 2112MB or 2GB of your physical RAM.

How to use Sony ADPMAA Sony DSLT A58

How to use Sony ADPMAA with Sony DSLT-A58?

You have to change settings of your camera and external flash unit according to your lens.

a) If you use kit lens (18-55mm) or prime lens (50mm) - just set your shutter speed from 1/100 to 1/160. You don't have to use HSS.


b) if you use zoom lenses like Sony SAL75300 (75-300mm) - just set your shutter speed starting from 1/250 (or higher). In order to do that, you have to use HSS in manual flash mode (Sony F43AM) and you can set the flash power according to your requirement. I love using Sony F43AM flash because the flash "tells" you the distance in meters  from you to the subject matter when you can change its power level.



Multi-Interface Shoe Adapter Sony ADPMAA  supports both TTL and manual modes.

Asus Zenfone 2 the fastest smartphone

Is Asus Zenfone 2 the cheapest and fastest smartphone in 2015?


(I don't make the review. I just share it)

Even though the review used the old model of Intel Atom processor, you can see that Intel Z2460 has defeated Samsung Exynos and Qualcomm Snapdragon. 

Intel Atom processors are also used by many computer manufacturers in their netbooks for so many years. Therefore, the processors are capable enough to handle a multitasking environment of Windows 7 Pro including heavy applications like MS Office 2013, Photoshop, SPSS and many more. (History of netbooks)













More review: http://www.itpro.co.uk/644092/smartphone-processor-head-to-head-intel-atom-vs-nvidia-tegra-3-vs-samsung-exynos-vs-qualcomm-snapdragon/page/0/1



For your information, Samsung S6 uses the latest version of Exynos CPU and Samsung S4 uses Qualcomm Snapdragon.

How to protect facebook before being hacked

How to protect your Facebook before an intruder hacks it?

The first thing that you need to remember is to take these precautions into consideration before your Facebook is hacked by an intruder. If your Facebook has been hacked before seeing this blog, it is quite difficult to regain control of your account.


1) Password
Create a password for Facebook that cannot be guessed by other people. It is recommended that your password should contain at least 4 letters and 4 numbers (with/without 1 or 2 characters).  The most important thing is not to tell anyone your password even your girlfriend.

2) Add several email accounts and mobile numbers.
Make sure all passwords for your email and Facebook accounts are different.

Inside Philips DLP5200 power bank

What can you see inside a power bank?

Philips DLP5200/97  http://www.philips.com.my/c-p/DLP5200_97/usb-battery-pack

I have just opened my damaged power bank, hoping to replace the batteries. Unfortunately, the size of the battery is not the same like normal AA batteries.


You need to remove the sticker / label on the front cover of the power bank. Then, use a screwdriver to remove the screw. Use a thin ruler to open the casing. As you can see in the last picture that the batteries are larger than the Sanyo rechargeable AA battery.

Samsung Galaxy S4 versus S6

Samsung Galaxy S4 versus Samsung Galaxy S6


The speed of S4 is as (almost) fast as S6 because S4 has 8 cores with 2GB (total RAM), and S6 has 8 cores with 3GB (total RAM). I don't think you will see a lot of improvement in terms of speed unless you really  need the camera because Samsung has slightly improved  S6 camera and video capabilities.
