Good, it is pc133 but cas3 at 133mhz. Kingston will usually operate at a faster speed then rated, I will tell you what bios settings to set for the rated speed indicated. Then I will tell you settings that you can try to get more performance out of it. The first settings should work perfect and give much better performance then what you had before.
In spec settings: (Go to bios setup)
1. Advance Chipset Features
2. Set Bank 0/1 Dram Timing to Normal (this will set the ram timing to 6-3-3-3)
note: since your only using one dim now the other two settings (Bank 2/3/4/5) can be leaved as is, or you can set them to Normal as well.
3. Set DRAM Clock to HCLK<b>+</b>33M (not HCLK-33M) this sets your ram speed to 133mhz, 33% faster then what you had before.
4. Fast R-W Turn Around set to Enabled
Out of spec performance settings
experiment only when you decide that your computer is stable with the previous settings.)
1. Bank 0/1 DRAM Timing set to Turbo (sets a very agressive ram timing of 5-2-2-2) you might want to try a setting of Fast first. Test this setting before you go to #2 below.
2. SDRAM Cycle Length set to 2 (this may cause lockups but does give a significant speed boost) if you see instabilities then switch back to 3 or you can try less aggressive memory timings like Medium or Normal above and this setting of 2.*
*Just be aware that your ram was not rated for Cas2 at 133mhz but will probably work using Cas2.
Let us know how these settings work out and what your final settings turn out to be. There are a number of other optimizations that you can do if interested after you set your memory. Plus I can guide you in how to determine if your settings are maximize, sometimes the more aggressive settings are not the fastest settings due to recoverable errors but still hindering overall performance. Once you are done with the memory part we can work on your graphics card optimum settings.
