CAS2 - worth it?

[Guest]

On www.sharkyextreme.com's memory price guide, 256 MB ram CAS3 is $102 and CAS2 is $212! Is it worth it to buy the CAS2 RAM? How much of a performance boost do you really get? Seems that money would be better spent elsewhere...

Another question to ask along with this is: Can you just "overclock" your CAS3 by setting the BIOS to CAS2 and see if it works? What's the downside to doing that?

 

[Guest]

Yes it IS!
But you don't have said what brand these are.

The Bios trys to run CAS 2, but the memory won't work in CAS2! as it can't react quick enough.

Just for kicks I set my BIOS RAM settings to PC133, CAS2 even though it is rated for PC100 CAS3. Somewaht surprisingly, the power on memory tests ran fine, the MB/S from Sandra went up by ~20% (ALU 384 -> 468 and FPU 415 -> 575), and the RAM seems to run nice and cool (not even warm to the touch). It's been this way for hours of solid use. Did I just get lucky?

Well my advice would be to try compiling linux kernal or other sensitive test/operations. And What the heck if it works it works, you may get more freezes/fatal exceptions
that dont seem related to this, but basically the system runs slighly more unstable with cas 2 even with cas2 ram
personally for the 3-5% overall boost i just run mine at cas 3 still get over 110fps quake 3
