AMD Launches Low Power Consuming 6 Core Based Server Class Processors

Intel might have been dominating the sales chart in the Consumer Processor Market, but AMD is still highly competitive with Intel in the server market. AMD’s Istanbul Processors have been able to compete quite successfully with Intel Dunnington 7400 series of Processors, even though Intel Server Class Processor’s performed better than AMD Processors. Today AMD launched 2 new 6 Core based Server Class Processors build on the 45nm fabrication process featuring low power consumption.image

AMD previous server class processors were also build on the 45nm fabrication process but they had a max ACP of 75W, while the newly launched Opteron 2373 EE and Opteron 2377 EE   feature a ACP of only 40W. AMD processors have been able to match Intel server class processors in pure clock speed terms and have also been successful in providing   lower power consumption.

Readers should keep in mind that AMD uses ACP method to calculate the power calculation of their Processors, instead of the usual TDP method used by Intel.

Tutorial: Optimising DD-WRT Firmware

If you guys have read my tutorial on Flashing DD-WRT Firmware On Your Wifi Router, then this tutorial I am going to tell you guys on how to Optimise the DD-WRT firmware for better performance.

Step 1: To access the setup page of your wi-fi router after you have flashed the DD-WRT firmware, you need to open your browser and type 192.168.1.1 and press enter. You will first be asked to enter a username and password which you will be asked henceforth to access the settings page of your router. After you enter a username and password, press change password to continue.

1

Step 2: The first page which opens by default is the Status page of the router and shows the current status of your router.

2

Step 3: After this users should click the setup page and setup their Wi-fi router so as to use it properly with their existing DSL connection.

3

Under the Network Setup category, you can change the Local IP Address to whatever you desire. From next time if you want to enter the settings page of your Router, you should enter the IP Address which you have entered here. I recommend changing the default Local IP Address so as to avoid the conflict of the Local IP Address between your Wi-fi router and your ADSL Modems, as the settings page of most of the ADSL modems can be accessed only via 192.168.1.1. Make the required changes and leave other things on their default value and click on “Apply Settings”. Keep in mind that the “Apply Settings” option saves the settings of the router permanently by writing it to the NVRAM of the router whereas the “Save” option only saves the changes you made to the settings page temporarily.

Step 4: After you have saved your settings and your router has rebooted, you need to go to the Wireless page on your router settings page.   Make sure that the Wireless Mode is set to AP which stands for Access Point. If all your devices will be using only the b or g wifi network, then select the respective option from Wireless Network Mode. Keep in mind that wireless g is faster than b but most of the old devices don’t support wireless g network. Enter a proper name for your Wifi network under the Wireless Network Name (SSID). The Wireless Channel option allows you to select which frequency your wifi router should use. You need to play around with this option from time to time as you need to make sure that you use a totally isolated frequency so as to get the maximum wireless network range possible. The more wifi networks present in your area using the same Wireless Channel as your wifi router, the less will be the network range of your wifi router. If you want keep your Wifi network hidden, select ‘Disable’ under Wireless SSID Broadcast or vice-versa. After making the necessary changes, don’t forget to save your changes by clicking on “Apply Settings”.

Step 5: After this you need to go to the Wireless Security tab under the Wireless page. There you will find the required options to protect your wifi network. It is highly recommended that you protect your wifi network so as to prevent unauthorised usage of your Internet. 4

Keep in mind that you must chose from Disable, WEP, WPA Personal, WPA Enterprise, or RADIUS. Also make sure that all the wifi devices in your network use the same security mode. Keep a note of the pass phrase which you get or set as you need to enter the pass phrase in all your wifi enabled devices when they connect to the wifi network for the first time.

Step 6: After this go to the Advanced Settings tab under the wireless page. Disable the CTS Protection Mode and WMM (Wireless Multimedia Support). Keep the rest of the settings at their default values. One interesting option to note here is the ‘TX Power’ option. This option allows you to increase the amount of power supplied to the wireless antenna’s of your wifi router. Increasing the TX Power to a certain extent may increase the range of your wifi network but if you set a value too high, your router may burn.

Step 7: Another interesting and useful option present in the DD-WRT firmware is that it allows you to restart your wifi router after a certain period of time or on a fixed time everyday or maybe on a fixed day every week. To access this useful option you need to click on Administration->Keep Alive.

5

Make the required changes according to your needs and then click on Apply Settings.

I hope this tutorial of mine will allow you to extract the maximum from your wireless router. If you guys have any doubt, please feel free to leave a comment so that I can help you.

Microsoft Xbox 360 Elite Gets A Price Cut

Sony just a few days ago launched Playstation 3 slim sporting a lower price tag and it seems that Microsoft is all set to compete with the newer PS3 ‘Slim’ by reducing the prices of both Xbox 360 Elite and Xbox 360 Pro. The Xbox 360 Elite is all set to become cheaper by 100$ while the Xbox 360 Pro will be priced at 249.99$ from now on. Microsoft also announced that the Xbox360 Pro console, which has been discontinued, will be available at the discounted price only till the stocks last.

Xbox-360-Elite-2

Shane Kim, corporate vice president of strategy and business development for the Interactive Entertainment Business at Microsoft Corp said –

If you’re looking for deep experiences that don’t require deep pockets, now is the time to purchase an Xbox 360. We’ve got the best games, a vast library of TV shows and movies, new music experiences, more ways to connect friends and family, and so much more on the horizon including Project Natal’ — no controller required.

The Xbox360 Elite and PS3 Slim are now priced exactly the same but the PS3 Slim has a very important advantage over Xbox 360 Elite that it offers an in built Blu-Ray device as well.

Sony Still Loses Money On Every PS3 Slim Sold

A few days ago Sony had launched the PlayStation 3 Slim and had reduced the price of the “fat” PlayStation 3 to 299$ or just ‘299’ everywhere across the world. Sony also announced that it will be phasing out the ‘fat’ PS3 soon and that the ongoing ‘299’ offer is available till stocks last. The new ‘Slim’ PlayStation 3 not only sports a cheaper price tag compared to its predecessor but it lacks PS2 compatibility. Today Times Online had a brief interview with Sony Computer Entertainment’s Kazuo Hirai. In the interview Mr. Hirai told Times that Sony still loses money on the newer itinerant of Playstation 3.

Mr Hirai also told that even though Sony loses money on every Playstation 3 sold, the platform as a whole is still profitable. Mr. Hirai also said that even though Playstation 3 sales have been slow compared to PS2 sales, but everyone should keep in mind that PS3 has a life-span of 10 years so in the long time sales will eventually pick up.

AMD Set To Release Many New Inexpensive Processors

AMD is all set to fight against Intel’s Core i5 and Core i7 processors which is due to be launched this September, by releasing many new cheap dual core and quad core processors. The month of September has always been auspicious for the Computer Industry as along with Intel and AMD, even Nvidia and ATi launch new products in the market. The ongoing recession has not been able to dampen their spirit.

AMD will be releasing 10 new processors in all. Their specifications and model number are as follows -:

Athlon II X4 630 (2.8 GHz, TDP = 95 W);
Athlon II X4 620 (2.6 GHz, TDP = 95 W);
Athlon II X4 605e (2.3 GHz, TDP = 45 W);
Athlon II X4 600e (2.2 GHz, TDP = 45 W);
Athlon II X3 435 (2.9 GHz, TDP = 95 W);
Athlon II X3 425 (2.7 GHz, TDP = 95 W);
Athlon II X3 405e (2.3 GHz, TDP = 45 W);
Athlon II X3 400e (2.2 GHz, TDP = 45 W);
Athlon II X2 240e (2.8 GHz, TDP = 45 W);
Athlon II X2 235e (2.7 GHz, TDP = 45 W).

The suffix ‘e’ in few processors means that they are energy efficient model’s and will consume less power than their counterparts. All the above processors don’t seem to challenge the Intel Core i5 processors in any way. All the above processors are meant to be highly value for money and will be priced very competitively.

AMD Dx11 Graphics Card Pictures Surface

AMD had demonstrated working samples of their Dx11 “Evergreen” based Graphics Card way back in CeBIT 2009 held at Taipei this year but AMD is yet to launch them. I have earlier already blogged about AMD “Evergreen” Graphics Card and its release date. Today a member at ChipHell forums posted few pictures of the upcoming RV870 graphics card. According to the information which he got, it seems that this graphics card is all set to replace the HD4770.

RV870 pic 01

The cooler on the above graphics card definitely looks big and it seems that this card is going to run very hot. The Card also comes with a 6 pin molex power connector.

RV870 pic 03

From the above picture it is clear that the card is using a Dual Slot Cooling design. The rear panel of the card also features 2 DVI ports, one Display Port and one HDMI port.

Apple Releases Two New Firmwares For Mac

Few days ago I had reported that the new MacBook Pro’s equipped with 500Gb Seagate Hard Disk’s where having freezing issue’s followed with a click sound. Well today Apple has released a new firmware with the firmware ID being 0007APM2. This new firmware release will hopefully “reduce certain infrequent noises   made by 7200-rpm drives”, as Apple puts it. Apple says that only users who had purchased their Mac from June 2009 need to update the firmware but then there is no harm in updating the firmware even though you are not facing any problem.

11906_large_Apple_HDD_Firmware_Fix

The firmware weighs in only 3.7Mb and users need to use the Hard Drive Update.app found under Applications/Utilities to update the firmware. Apple also released another firmware update for all unibody Mac’s sold in 2009 which were most probably using a Broadcom chipset for Wireless Bluetooth facility. Some users were getting very poor Bluetooth reception and so Apple released a new firmware so as to solve the poor Bluetooth range. This firmware update also fixes various bugs and brings in a few performance enhancements as well.

AMD Dx11 Graphics Card Shipment Date Announced

AMD has announced that it will start shipping Dx11 based graphics card by the end of Q3, 2009. AMD has now decided that they will soft launch their Dx11 Based “Evergreen” Graphics card on September 10th. AMD had already shown demonstrated their Dx11 based graphics card during the Computex held this year. More information about AMD’s “Evergreen” graphics card can be found in an earlier post which I had made. Here is the link to that post.

AMD Launches Phenom II X4 965 Black Edition Processor

AMD Phenom II processors turned the fortune of the company around. The Phenom II processors launched by AMD were based on the 45nm fabrication processor which allowed AMD to stuff the processor with more L3 cache and increase clock speed and thus improve the overall performance of the processor. AMD Phenom II processors proved to be a very good competitor for Intel Core 2 Duo and Quad Series of processor. AMD Phenom II processors were able to defeat their similarly priced Intel counterparts easily, but Phenom II did not get AMD the performance crown back. Intel now is all set to launch their Lynfield line-up of processors in September this year which will surely put AMD in the backseat with their performance.

AMD currently does not have any answer to Intel’s upcoming Core i5 processor, but AMD is trying to make as much money as possible before Intel launches their new line-up of processors. So AMD is trying to extract as much processing power possible from their current 45nm processors by making them run at increased clock speeds. AMD Phenom II X4 being one of them. Here are the specifications of AMD Phenom II X4 Processor –

table

As you can see the processor runs at 3.4Ghz and has as unlocked multiplier so as to facitiliate easy overclocking. AMD Phenom II X4 965BE currently is “best” processor AMD can offer and even then the processor has a measly price tag of 245$. You can read the whole review of this processor over at Xbitlabs.com

Xbox 360 Elite All Set To Replace Xbox 360 Pro

The recession has hit the game console industry hard. The gaming console companies have not been coming up with good sales figure recently, though still the cheapest gaming console, Wii leads the sales chart. Rumours are floating that Microsoft is all set to replace Xbox 360 Pro with the Xbox 360 Elite with the help of a price cut. The attached picture (Source: Dailytech) with this post shows the price tag of the Elite version to be 299.99$. 11838_large_504x_300pro

Microsoft may be cutting prices of its console, but Sony is not at all interested in doing so. Though again there have been rumours that Sony may launch a “Slim” PS3 on August 18 along with a price cut announcement, but till now nothing has happened. Even Microsoft has not confirmed anything, so readers should take this post with a pinch of salt.
