Hari’s new graphics card

by

Hari’s new graphics card has arrived, and so I fitted it earlier today. We went with an Inno3D card based around an nVidia GeForce 7600 GS chipset, since it seemed to represent the best value for money for our budget and was compatible with Hari’s computer – it doesn’t have PCI Express so we needed an AGP card.

As performance goes, the card is an immense improvement. Using World of Warcraft as a benchmark, before, she was getting an average of between 10 and 12 frames per second with all the settings turned down for maximum performance (but low detail). With the new card, she gets a constant 50fps, with many of the enhancements enabled, such as texture detail, terrain distance and spell effects. It looks fantastic, and is very smooth.

This now means that Hari finally has the gaming performance that she’s been wanting for so long, and ends an upgrade process that has seen a new external hard drive, new memory and now a new graphics card. All in all, we’ve spent £220 on new hardware, but seeing as it’ll add value to the computer, and make it less obsolete in future, it should be worth it.

Or, at least, it ends for now. She now wants a new power supply so that her graphics card can run at maximum performance. I think we can pass on that.

Actually, I didn’t realise that the card needs to have a direct connection to the power supply as well as being connected to the motherboard through the AGP socket. I’ll get it sorted soon.

Graphics card recommendations

by

It now looks like Hari needs a new graphics card. The extra memory arrived yesterday, as expected, and has made something of a difference to the computer. Switching between World of Warcraft and any other program is instantaneous, whereas it used to take several seconds and result in considerable hard disk noise (presumably Windows swapping data between physical and virtual memory). Plus, aspects of Warcraft, such as navigating around cities and instances is noticeably smoother. But there’s no real improvement to the number of frames per second it can manage during general play. Which was one of the main aims of the upgrade – the other being preparation for the eventual installation of Windows Vista.

Having looked at the recommended requirements of World of Warcraft, it looks like it’s Hari’s graphics card which is to blame. She has a card based around the nVidia GeForce 5200 FX chipset, with 128 MB of graphic memory. It’s not a bad card, but it’s likely to be missing some of the advanced features which more modern cards have, which in turn puts more pressure on the CPU and slows the whole computer down.

Overall, her computer spec is as follows:

  • 2.80 GHz Pentium 4 processor
  • 80 GB hard drive, with an additional 80 GB external hard disk
  • 2 GB of Corsair memory
  • 128 MB nVidia GeForce FX 5200 graphics card
  • Windows XP Home Edition SP2

(plus all of the usual gubbins like a DVD rewriter and Ethernet)

The processor should be fine – World of Warcraft only requires a good 800MHz processor and recommends 1.5 GHz. Furthermore, CPU usage is relatively good – we ran Task Manager last night while she was playing and it rarely went over 80%, averaging about 50% – if it was close to 100% a lot then I’d be more worried. We can’t fit any more RAM as 2 GB is the maximum it can take, but judging by our experiences with the new RAM so far adding even more wouldn’t have made much difference. The internal hard disk should also be fine as it has plenty of free space (though it may need defragmenting, I can’t see it making a huge difference).

Software-wise I have done almost all I can. Though Hari is not a computing student, she is very computer literate and knows the risks of viruses and spyware and so she has AVG and Windows Defender running (as well as Spybot and Ad-Aware). There’s very few background applications running, and even if they were, they’d be using RAM and CPU which we know aren’t issues.

Which leads me to the conclusion that the graphics card is the weakest link. I’ve upgraded it to the latest Forceware drivers, but I honestly don’t think it has made a difference to performance. If we’re going to get decent Warcraft performance, it will probably need to be replaced.

Whatever the replacement is, the main limitations will be that it has to be AGP – the motherboard does not support PCI Express – and that it only takes up one slot as the computer has a small form factor case. Though there is space for a card which takes up the equivalent of two slots, it would render the only PCI slot useless – admittedly it is empty now but it could be used for something in the future.

You may wonder why we’re spending all this money on an old machine – after all, we could probably get a new one for the money spent so far (about £150). But there’s not much fundamentally wrong with the core components, and a few upgrades should make it very powerful. I also doubt that the money would get a computer designed for the uses it would get, i.e. gaming.

It’s unlikely that we will buying a new graphics card just yet – it’s likely to be later in the yeah when Hari has some more money. But I’d like to know if you all think I’m right with diagnosing the problem, and if you have any recommendations for good graphics cards, preferably ones under £75.

Memory upgrade question

by

Here’s a question for all you memory techie nerd people out there:

Given the choice, would you go for Crucial memory, or Corsair Value Select memory?

The reason why I am asking is that I’m finally getting around to upgrading Hari’s computer, now that memory prices have fallen far enough for it be a little over £100 for a full 2 GB of RAM. Crucial have the memory she needs at £108, but they’re currently out of stock and there’s no indication as to when they’ll get stock back in. Scan, on the other hand, has Corsair Value Select memory available now for £107 including delivery.

Obviously the two cost the same so price isn’t an issue, but should I wait and buy Crucial memory, or get Corsair memory now? The fact that it is ‘value select’ seems to imply that it might not be as good as Crucial’s memory but I have no idea whether this is actually the case; all I know is that Crucial and Corsair are good brands.

Obviously it would be nice if she could afford high quality gaming memory but this is about the best we can do for now. Any thoughts are welcome.

Memory upgrade

by

Today I finally got around to upgrading the memory in my Mac Mini. Since buying it last year it’s had 512 MB of RAM, which is fine for general computer-ry stuff (reading email, browsing the web, maybe running iTunes in the background) but lately it’s been used more and more for playing World of Warcraft, which is a very memory-intensive program. With it running, doing anything else on the system is, at best, difficult – switching between World of Warcraft and, say, Firefox takes a long time.

I ended up buying the memory from Crucial – I’ve bought from before and had no problems, and this time was no exception. I ordered the memory yesterday morning, and despite going for the free delivery and not the more expensive guaranteed next day delivery it still came today, which is excellent. Crucial also happened to be cheaper than buying Corsair memory from either Scan or Dabs, and I’d rather not have generic memory if I can avoid it.

The reason why I have been putting the upgrade off isn’t so much the cost aspect (which ended up at £85 for 1 GB of PC2700 DDR RAM), but the actual upgrade itself, and in particular taking the unit apart. It’s a very small unit and the case isn’t screwed on – you actually have to pry it open with a knife – I used a standard putty knife from Wickes. Because my unit also has Airport and Bluetooth, you have to then detach one of the antennae before then lifting the RAM out and inserting the new module. Thankfully, there are videos which explain this process – I really would not have bothered if I hadn’t seen it being done first. One thing I did do, however, was boot the computer before putting the lid back on and making it sure it worked – after going through all the effort of taking the machine apart I didn’t want to have to do it all over again just because the module wasn’t seated correctly, for example.

Thankfully, the upgrade worked, and now the Mac has double the memory to play with. It’s not a seismic difference in speed but it does feel snappier; still, my MacBook, with its Intel Core Duo processor, beats it when playing WoW. But not by quite so much.

It’s here

by

The MacBook is here, and currently downloading about 10 system updates. Unfortunately, I have an exam in 3 hours so I can’t play with it much, but for now I can say the following:

  • Wow, it’s so small and light
  • The battery seems to be charging up really quickly
  • I really wish my Mac Mini had an Apple Remote

More later (including photos), after I’ve spent 2 hours sat in a room writing about internet security and encryption protocols.

Screenshots on a PocketPC

by

Since it took me a while to find out how to do this myself, I’m going to use this opportunity to tell you how to take screenshots on a PocketPC or Windows Mobile device – in my case, Windows Mobile 2003.

First of all, you need to know that, as far as I can tell, your device does not have a screenshot capability built in. It’s not like a Windows machine where you can hit Print Screen or a Mac where you can hit Cmd+Shift+3 – you will have to install some software first. I’m sure there’s some fancy-pants shareware jobby that will do the job painlessly but in this instance we’re going to use Pocket SnapIt (link no longer available), which is available for both normal Windows Mobile/PocketPC devices and Windows Smartphone handsets. There’s also a Windows version for your PC. It’s free and open source.

Choose the relevant package – for my Dell Axim x50v, I chose the PocketPC package – and download it to your device. This may mean downloading it to the Mobile Device folder in My Computer and then using ActiveSync to send it across. Then, click on the cabinet file on your device to have it install. If you’re using Windows Mobile 2003 (and probably 5.0 also) you’ll probably get a warning saying that the application was designed for an older operating system – you can ignore this. Now, go to Programs and run the newly-added Pocket SnapIt icon.

You’ll now need to define a hotkey to trigger the taking of screenshots. I chose the ‘/’ character – to set this, click on Menu and select Options. Then click Menu again, expand Options and choose Capture Options. Now click Menu a third time and click Select Capture Button. Click OK and then select a key on the keyboard. Click OK to go back to the main screen, and then click Start.

Now, open up the program you want to take a screenshot of and press the trigger key – you should hear a noise when you do. You should then find a bitmap file in your My Documents folder call Snap001.bmp – this is your screenshot.

You can see my effort further up the page – this was a shot from Skype for PocketPC. As you can see, the capturing mostly works but it chokes on the font smoothing, so you may want to consider turning this off first. You’ll also need to change the image format to something other than bitmap if you want to post your screenshot on the internet (since bitmaps are not compressed) – PNG is probably the best format to go for. The image I posted is less than 13KB.

iPod Recycling Programme

by

At the risk of annoying Dave, who’s just bought a iPod Mini to replace his 2G iPod, Apple have announced an iPod recycling programme, whereby if you take your old iPod to an Apple Store in the US, Apple will recycle it free of charge and give you 10% off a new model (if you buy one on the same day). The old iPod will then be dismantled and recycled within the US, so that no hazardous chemicals, such as lead, are shipped overseas.

It’s a good move by Apple. On the one hand, they’re ensuring that unwanted iPods are disposed of and recycled properly, instead of being dumped on landfill sites. And at the same time, they’re encouraging users of old iPods to upgrade to newer models, thus bringing the company more revenue.

Let’s just hope that Apple extends this to other countries and that other manufacturers take a hint and adopt similar policies.

Quickly compress PNG images

by

Before posting any PNG images on here, I use the open source Pngcrush tool to compress the images as much as possible first. Even when I set the compression to its highest value in programs like IrfanView, Pngcrush is still able to make most images even smaller.

Unfortunately, Pngcrush is a command-line tool, so it’s not the easiest tool to use in Windows. So here’s how to add a ‘Crush’ option to the context (right-click) menu in Windows Explorer for quicker crushing.

Firstly, you’ll need to download Pngcrush, which is availble at Sourceforge. You’ll want the win32 version. Download it and unpack it somewhere.

The instructions that follow are for Windows XP; for older versions they’ll be a little different.
Open Control Panel and choose Folder Options. Select the File Types tab, and scroll down to the ‘PNG’ entry. Click on ‘Advanced’, then click on ‘New…’.

In ‘Action’, type Crush, and in ‘Application used to perform action’, type the following:

C:\Downloads\pngcrush\pngcrush.exe -e 2.png "%1"

The first portion should be the location of the pngcrush.exe file that you extracted from the archive. The ‘-e 2.png’ bit specifies what the outputted PNG image will be called, which in the case it’ll be the filename with ’2′ appended to it (so the crushed version of ‘catpicture.png’ would be called ‘catpicture2.png’). You could also use the following:

C:\Downloads\pngcrush\pngcrush.exe -brute -e 2.png "%1"

This does the same as the above but does a ‘brute force’ crush – rather than use one of a few common methods to crush the file, it will use all of them. It’ll take longer, especially on older hardware, but may result in a smaller PNG file.

And you’re done. Now, when you right-click on a PNG file, you can select ‘Crush’ and have Pngcrush your image for you. Remember that the compression is lossless – you won’t lose any quality by using the tool.

New computer

by

My parents are now the proud owners of a new Packard Bell desktop machine. It’s pretty good – AMD Athlon XP 3000+, 512MB RAM, 80GB HD, DVD rewriter, 64MB onboard graphics (since I doubt my parents will be playing Doom 3 any time soon), TV tuner card and multi-function card reader, plus the usual Ethernet, 56k modem, keyboard, mouse and related gubbins. There’s also a 17″ TFT monitor with built-in speakers that looks very nice and occupies much less space on the desktop. The whole setup is a rather fetching black and silver colour – much better than the beige boxes we used to have.

It comes with Norton Internet Security Suite 2004, but it’s only got 90 days of free updates, after which it’ll presumably demand payment of us, so I’m replacing that with the standard firewall in XP SP2 (which we had to install) and McAfee VirusScan Enterprise which is decidedly less annoying.

In fact about the only thing it doesn’t have is a floppy drive, which I suppose is a sign of the times.

Bollocks bollocks bollocks

by

My hard drive has failed. I was using it normally, and then most apps froze and then I got a BSOD. I rebooted, but the computer wouldn’t boot, citing an IDE error 🙁

The most annoying thing is that the machine is only 10 months old, and that I went for a Toshiba machine because I expected it to be better than my previous laptop, a Samsung, which at least made it to nearly 18 months before dying one me. Toshiba supposedly make good laptops.

Thankfully, it’s still be under the 12-month manufacturer’s warranty, so the reseller that sold me the machine are going to get an earful once I dig out their number. Still, I’m downloading Knoppix in the hope that I can salvage the more important data as I imagine that the ‘repair’ will merely consist of a new hard drive. In the meantime, I’ve requested a quote from OnTrack data recovery should damage to the drive be severe.

Update: Knoppix can see that there’s an HD in the system but it can’t read anything off it. This isn’t looking good. On the plus side, I do have internet and an office program and I can FTP stuff if I need to save anything.
