I bought this kit last weekend from local Fry's and am using it with my 400SC. It works fine with it. Geil, I think, has heat spreaders. This kingston is CL3, Geil may be CL 2.5, I didn't check.
I am having a problem with my 400SC. Let me see if anyone here have any suggestions. My Viewsonic VP2001 LCD doesn't turn on when the turn the 400SC on. I read on the web not to share the powersupply cable that goes to ATI 9800PRO, my video card. I did this but it is still not working. Integrated Device Preference in the BIOS is set to AGP. Does anyone have any clue what might be wrong.
