For the performance user always having a top end system is important. I've always been very proud of the parts I used and in away it's  no longer just a computer, it's my creation. Now, I work  at computer store as a service tech and  just about everyone these days seems to be equipping their computers with 128 MB+ RAM, so I figure, "Heck, if Joe Blow has 128 MB, I need more!"
 
                                                                                                  So I went shopping… I could have bought the generic 256  MB DIMM's  PC-133 for  $110CDN, but again, having pride in my components, I decided against equipping my machine with a weak memory subsystem. Instead I picked up some Apacer 256 MB PC-100 SDRAM. 
 
Now I know what you're saying, "what do you want PC-100 
RAM for?!?" Well it's simple, I do my homework before I buy. While looking 
over the memory available at my local computer store (not the one I work at), I 
noticed that these 256 MB modules were using the same DRAM as the Mushkin 
Rev. 3 PC-150 uses! Lucky break? You bet! Of course, the Apacer sticks were 
quite a bit pricier then regular generic memory. In the end I paid $280CDN 
for two sticks, or for the mathematically inclined $140 each. The chips 
were Infineon HYB39S128800CT-7.5, C2.                                                                                                                                                
With 512MB of memory I was satisfied in my systems status once again. 
 
I marvel at how technology has progressed. I have more ram then my old 
486DX/33 (oc'ed to 40 MHz!) had hard drive space! Well back to the present. Yes, 
I'm being vain here, just getting more memory because I wanted more then the 
average person. Then again, knowing that the DRAM can run at CL2 at 150 
MHz, I was really excited on how high I could clock the RAM up to. 
                                                                                                  
CAS2 150 MHz! I find it  humorous how Sandra says this memory is only certified to run at up to 100 MHz. One thing that really  surprised me was that even at a CAS3 rating, the RAM would go no higher then 152 MHz! If I tried, it  would result in a 'no post'. Here are the system specs of the machine I tested the Apacer 128MB PC100 out on:
 
Athlon "T-Bird" 1 GHz AVIA 0110 (will do 1.53 GHz!) at 1.2 GHz at various BUS speeds 12 x 100 MHz 9 x 133 MHz 8 x 150 MHz 
Asus A7V133 BIOS 1004 BETA 002-D Via 4in1 4.29V

I know what you're saying. "What's the deal with  all the cards?" Well, this is supposed  to represent a real life system, and most computers have quite a few devices. First off with the Sandra Benchmarks:
