Speeding up an old pc

I found a neat trick to speed up old machines. Don’t dump them! At least anything above an athlon xp 2400+ (i have done this experiment on this one). For long I have been using this desktop of mine which has the following configuration – proc as mentioned above, a7n8xvm/400 ram, onboard gforce4m, 512+256 ddr1 ram 333mhz, ide hdd pata 120gigs. And then suddenly one fine day after taking lots of virtual abuse my hard disk died. It had served me well, though, taking the beating of torrent writes and simultaneous songs / movie playbacks. And not to mention the unholy windows fragmentation curse.

It was time now I decided to run to the market and buy another hdd. So my quest began and after many phone calls and searching online on estores I realised that the dear old PATA hdds were really a rare entity. The stores which had them priced them above the bigger brother – SATA I and II.

And then lightning struck my ear and few of my brain cells got electrified -  why not put the sata drive in my pc. How?? So after searching I found two solutions – put in a pata to sata adapter, and the other a sata/pci card. The latter was interesting since the former would give me no advantage of speed. And we went on and added the card and the sata hdd, did a win7 installation and the speed was amazing.

Why should it not be? Cause imho, the ide bus is the biggest bottleneck in a pc. And with SATA this was removed. So even with an not-so-old configuration, things can run smoothly. Just make sure you have the pci-sata dos drivers at hand when installing win7.

AMD launches athlon II X2 250 and Phenom II X2 550 Black edition

AMD launched the Athlon II X2 in computex 2009. It is 45nm based, so should run cooler and should consume less power. Has a total power rating of 65 watts. Supported on both am2 and am3 sockets, hence ddr2 and ddr3 memory are supported by the inbuilt memory controller.
Phenom II X2 550, codenamed Callisto, gets 6 MB L3 cache, while the athlon has no L3 cache. The Athlon runs at 3 gigs with 2 mb of L2 cache. The price tag is competitive, being $87, for the athlon.

L1 cache 128 k =
(64 k instruction per core +
64 k data per core)
L2 cache 1 mb per core
memory controller 128 bit integrated
memory controller speed 2 gigs with dynamic power management
supported memory ddr 2 800 mhz
ddr3 1066 mhz
hypertransport hT 3, 2 gigs x2
sys to proc bandwidth 33.1 gigs per sec (17.1 gigs + 16 gigs)
socket am3 (939 pin mpga)

Cooler laptop

My acer 7530G laptop was running hot, running close to 75 degrees celsius when fully loaded and at 68 degrees under average load. I thought of something to cool it down. I tore it apart, and increased the size of the vents which cool the heatsink. I cut some of the grids. Assorted pics below.

The work done

Here is the system snap after the mod, note the cpu temp : 58 degrees :)

some bluewhite64 packages

here are some bluewhite64 12.2 packages

note that you would require linux kernel 2.6.29.2 and its headers installed in order that these may function correctly, they are built for the x86_64 processor

compiz requires kde4, yakuake 2.8.1 is meant for kde 3 only, yakuake is a quake like drop down terminal. cpu freq utils requires you to enable frequency scaling in the kernel.

To compile a kernel meant for amd turion x2, nvidia sata, atheros wi fi, broadcom tg3 based ethernet, xfs enabled, you can download the linux kernel source for version 2.6.29.2 from kernel.org and use this configuration file to build it. Download the kernel, (normally a tar.bz2 or tar.gz) to /usr/src, unzip it in the folder, copy the configuration file to /usr/src/linux, rename it as .config, build the kernel using make. Make sure /usr/src/linux points to /usr/src/linux-2.6.2.2

currently these below packages are only for testing, feedback is highly appreciated

compiz version 0.8.2

compiz-bcop-0.8.2

compiz-plugins-main-0.8.2

libcompizconfig0.8.2

compizconfig-backend-kconfig

cpufrequtils

yakuake-2.8.1

The GPU rat race

AMD has announced the first 40nm graphics processors running in ATI Molility Radeon HD 4860 and ATI Molility Radeon HD 4830. These have suppor for directx 10.1, and are aimed for the laptops, did i not say they are mobile. So what else is new? GDDR5 memory, twice the bandwidth of GDDR3. Lower power consumption thanks to ati powerplay, powerxpress and switchablegraphics. ASUS is supposedly the first to launch them in their laptops. The max resolution they can offer are 2560 x 1600. That would be a sight! But that would be in AC mode only, aww! This is a link to some images.

Rivals Nvidia have launched two new notebooks gpus – geforce gtx 280m and gforce gts 160m and 150m. These have NVIDIA Hybrid power technology, NVIDIA PhysX effects, CUDA computing architecture. The retailers having these in their laptops are Asus, Clevo and MSI.

Lets wait and watch for some comparison tests.
