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.
