Tuning and Benchmarking a Dell GX 270 SFF - upgrading the AGP video card

As seen earlier, maxing out memory and adding a dedicated video card only produced an approximate 10% performance increase. I wanted to see just how good the NVIDIA GeForce MX440 AGP card was so I went to the Passmark software site at  http://www.videocardbenchmark.net/low_end_gpus.html to compare low end video cards. I discovered that the MX440 card was really low end, scoring only a 4. I looked around for some better cards realizing I had a double handicap. First, the video slot on the GX 270 SFF was AGP and second, only a half height card would fit in the SFF case. This eliminated a LOT of cards. Looking on eBay eliminated a lot more. Eventually I found a Radeon X1300 that was AGP and half height. I got it cheap and if it works I should get a big graphics boost as it it much faster than the MX 440 - see the test page at http://www.videocardbenchmark.net/gpu.php?gpu=Radeon+X1300 where it scored a 57!
Here is a pic:

I'm going to put it in the GX 270, swapping out the NVIDIA card, and hope I don't have driver problems.

Tuning and Benchmarking a Dell GX270 SFF P4 - Recap

I've run a series of tests on the 270 P4. Usually I run the test 3 times and take the middle score to avoid outliers. The base configuration with 1 MB of RAM and the integrated Intel 82865G video scored 86.1. Installing a NVIDIA GeForce MX440 AGP card but leaving the memory at 1 MB upped the score to 92.6.

I removed the NVIDIA card and ran the benchmarks on a config with 2 MB of RAM. It scored a 86.6.

Here is the detail:

I then reran the tests on the config with the NVIDIA GeForce MX440 with 2 MB of RAM and got a new score of 92.7.

The detailed benchmark is this:

To recap;
86.1 with original config (1 MB RAM, Intel 82865G integrated graphics),
86.8 with 2 MB RAM and the integrated Intel 82865G graphics,
92.6 with 1 MB RAM and a NVIVIA GeForce MX440 AGP video card,
92.7 with 2 MB RAM and a NVIDIA GeForce MX440 AGP video card - about a 10% increase.

Tuning and Benchmarking a Dell GX270 SFF P4 - Part 3

I upgraded memory from 1 GB to the system max of 2 GB expecting a nice performance jump as the easiest upgrade to a PC is to add memory. Nope. The overall performance actually went DOWN.

 So, let's look at the individual benchmarks to see what happened.

Overall rating went from 92.6 to 88.3 - a decrease of 4.6%.  Hmm.  Let's compare individual tests; Prior to memory upgrade CPU Mark of 329.8, after upgrade 328.8 not too much difference there. Prior to upgrade 2D Graphics Mark of 296.1, after upgrade 296.3 again, not to much difference. Prior to upgrade 3D Graphics Mark of 9.3, after 8.8. For some reason adding system memory slowed down the 3D graphics test by 5.4%. Continuing, prior to upgrade Memory Mark of 486.1, after upgrade to 2 GB, 577, an 18.7% increase. Close to what one would expect but not enough to compensate for the slower graphics hit. Finally looking at Disk Mark before 346.4 and after 341.9. Again a slowdown but only about 1.3%.
So I think I will go back, remove the GeForce card and compare the results with a 2 GB system memory upgrade.

Tuning and Benchmarking a Dell GX270 SFF P4 - part 2

I was going to add additional memory as the first upgrade to the base unit, but the integrated graphics chip bombed the 3D benchmarking test a couple of times so I decided to do a quick video upgrade. I added back the NVIDIA GeForce4 MX440 AGP card and when I rebooted the BIOS automatically recognized the card and overrode the integrated chip. I ran 4 tests and the 3D test showed a 7.5% improvement while the memory test  got 4.7% faster probably because the video card has its own memory and doesn't have to share system memory like the integrated chip.

Overall the system performance achieved a 7% speed increase with the video card upgrade.

Next step will be a memory upgrade.

Tuning and Benchmarking a Dell GX270 Pentium 4

This is my first project. Take a classic Pentium 4, in this instance an (in)famous Dell Optiplex GX270 SFF, and see how much better I can make the basic model by installing various upgrades. The GX270 model is infamous for being part of a large production run that had bad capacitors installed and which proceeded to literally blow up. Later, Dell ended up swapping out thousands of motherboards over this issue.

Here is the unit on the workbench. A Dell Optiplex GX270 with CD-DVD drive and a 3 1/2" floppy drive with a couple of front side USB 2.0 ports. These are readily available all over eBay for less than $100.

Here is the unit with the clamshell opened. A pretty nice piece of engineering fitting a lot of stuff in a small space. At this time there is an upgraded video card installed, but I am going to remove it for the base line tests.

Power it up and go to the Bios setup page to check things out. This is equipped with a Pentium 4 running at 3.2 GHz and 1 MB of DDR SDRAM.

 The BIOS leaves no options for any kind of overclocking.

The on board graphics is an Intel 82865G chip. It has almost no 3D power and in fact during testing failed the 3D test at least once.

For benchmarking I am using the 32 bit version of the Passmark V8.0 performance test suite. This is the best complete testing suite for PCs and is available for around $20 from Passmark.com. They also publish a huge variety of test results that users post. Very useful and interesting for testing. I ran the full test suite twice successfully and got overall scores of 85.5 and 86.1. Not too impressive but good enough for a baseline.

This is the detail page. Notice the very poor 3D results. Normally the first upgrade would be memory, but I'm going to put the video card back in.

Bare Metal PC League

I am going to start a FB page for people who are interested in "tuning up" older and legacy PCs. The page will give them a virtual place to ask questions, show off their projects and compare system specs and benchmarks. Eventually I'd like to even have some competition ladders and/or events. Here's the logo.

Accessing an old IDE HD with a USB Adapter

This is a continuation of my last post from 2014 in which I wanted to check for pics on an old IDE HD in a USB enclosure but couldn't get it to power up. I wanted an adapter so I could take a bare IDE drive and convert it to USB. I ended up buying this:

Inside are four pieces, a power cable, a power adapter, a power cord and the IDE/USB adapter pictured on the box cover.

I connected the power cable/transformer to the power connector and the IDE adapter to the IDE pin connector on the drive.

So it looks like this:

Then plugged the power cord into the adapter and the wall outlet and then the USB at the end of the IDE adapter into a port on the PC.

Waited. Got the Windows ping announcing it had noticed a new USB device installed and then went to My Computer and found it as Drive I:

Notice it is seen as a "DiskGo", the original name of the unit. Clicked on OK and saw the directory of files.

Started drilling down into the folders looking for pics. Success!
