PC150 -- Cas 3 to Cas 2 worth it?

I am trying to tweak as much performance out of my p3 800/133 as I can since I won't have the cash to upgrade for another year or two. I have my pc133 runing at 150 Cas 3 right now and my P3 is at 900/150. I want to sell my current memory (which does not do cas 3) and get some pc 150 Cas 2 so I will end up spending about an extra $15-20. Is the jump from 150 at cas 3 to cas 2 worth the trouble and the extra $15-20?
 
Speed is the same in computers as it is in racing, Speed cost money, How fast you want to go, Well in a bench marks the cas 2 will beat cas 3 all day long but in use you wouldn't see a diff. If it was me and I could run cas 2 for $15 to $20 I would but I use my computer for video and photo work
 
Just get the cas2, you won't wonder somewhere down the line if that cas2 would really have helped you. Plus, if memory serves me right, you should see a nice improvement going from cas3 to cas2.
 
games will really love the cas2. yes it is worth it.

...and you dont seem to mind going thru the buying/selling deal so go ahead.
at the least it will give you something new to play with for awhile 😉
 
Not to suggest these results are universal, but in a simple comparison on my system @133, CAS2 performed 3.5% better on 3DMark2001 SE. If you are putting the money into a high quality 21" monitor and the fastest video card & CPU available etc, to run 3D at 1600x1200 then certainly a few bucks for faster RAM is worth it, otherwise prolly not. It comes down to where the money is most efficiently spent to get the most performance.
 
Another thing is that the KingMax PC-150, even though the latest revision fixed a lot of compatibility problems, runs better on some motherboards than others. I have a 512 MB stick and it will only do 150 3-3-3 on a BE6-II, but it will do 150 2-2-2 on Asus motherboards. But you should see significant increases in your Sandra memory benchmarks and in gaming when you run CAS 2-2-2.

Did you know that you can return the stick to Kingmax (lifetime warranty) and they will send you a stick of the newest revision because of the incompatibility problem?
 


<< Kingmax PC150 SDram - 1x 512mb is slower then 2x 256mb sticks.

ran the tests myself. >>


Yes, that is true and also it 'should' be less overclockable. This is because of the memory 'density'. The more memory on a stick the higher the traffic on the DIMM connection and it can cause slow downs or limit the overclockability of the stick.
 
put the $20 in a "new computer" fund.. don't waste it on something that is meaningless.

you will *not* notice a difference between Cas 3 and Cas 2... benchmarks don't do anything for you .. i guarantee you wont' see a difference
