Will upgrading my ram help overclock to even higher speeds?

Question

Hi everybody.... here are my systems specs as of now
MSI 865PE NEO 2 (BIOS 1.9)
Intel P4 2.8C 800Mhz FSB @ 3.33Ghz 952Mhz FSB
Zalman CNPS7000-Cu / Arctic Silver Compound
4x256 Corsair TwinX 3200C2 @ 2-3-3-5-8
ATI Radeon 9800 Pro 128mb o/c to 400/360
HD1: SATA 36GB WD Raptor
HD2: WD 40GB ( ATA 133 )
Lite-On 52x Burner
Lite-On 16X DVD Drive
Antec True Power 550W
All wrapped up in a Thermaltake Xaser III V1000 Series Case (Black)
I am always looking to boost my system performance in any way I can... if I ugrade my ram from twinx 3200c2 to twinx 4000 will I be able to push it any more than I am now? Right now I run solid at 3.33Ghz... if I boost it to 3.36Ghz however my computer will eventually lock up and I am thinking its my ram holding me back.
I am still new to the overclocking side of the house but any advice would be appreciated. Thanks a lot

If you Choose a RAM that is DDR-4000 you will never have to run it at anything but a 1:1 Ratio if you stay at 250 MHZ CPU Speed (or PBS) or Lower, and at 250 MHZ you are "Freakin Flyin"...In order for you to chang your Memory Ratio or Divider, as some Call it, is to Go into the BIOS on the "Frequency and Voltage" Page and Choose the DRAM Frquency Option, if you have a P-4 (C) Chip that Runs on a 200 MHZ Proc. Bus Speed(PBS) and your memory is DDR-400 then at default it is 1:1 as the Memory and the CPU are running Syncronous with each other, in order to Change the Memory frequency to a 5:4 Ratio all you have to do is to Choose 333 MHZ in the DRAM Frequency Sub-Menu... Or if you are Running your PBS Overclocked to 250 MHZ PBS, and you have PC-4000 (DDR-500) installed, then to run it at a 1:1 Ratio you would Choose 500 MHZ in the DRAM Frequency Sub-Menu........Understand? .............Sean REILLY875
