How can I not understand this? (pics)

I have this ram
http://www.newegg.com/Product/Product.asp?Item=N82E16820146425
With a dfi lan party ultra-d, opty 165 (9 x 290) the cpu is rock stable.

I never really understood ram timings and values, which is why I'm here groveling for help.
This ram is rated @ pc3200. If I leave everything in ram options stock, I have to set the divider to 133 to get it to boot. Any higher and it restarts the instant it tries to load windows. Shouldn’t this ram at least boot at 166? What am I doing wrong?

If you're going to be overclocking a 2 gb set, I would start by changing the "cas latency" to 2.5 and "ras to ras delay" to 3. Try putting the divider back to 1:1 and slowly increase the fsb until you find a wall.

200, 166, and 133 refer to dividers. They don't literally mean "200mhz". 200 only = 200mhz if your HTT is at 200. At 290, you are trying to run you ram at 290mhz. 133 is 2/3 of 200, so if you increased your HTT to 290, 2/3 of that is 193mhz.

Thats what it was. I thought it was actually putting a divider there.

Thanks.

Actually, the ram is running at ~186mhz, not 200.

Its a lot easier to explain it as a divider based on the HTT rather than from the CPU. Its usually accurate enough, too.

Thanks.

I found this tool

and After I fiddled with it for a minute, it all hit me.

Sorry I missed your thread but I didn't find any mention about Mushkin here. If you need some tips for memory timings, etc PM me or ask here.

Hey, I know how you feel. I went to a presentation put on by Micron and it was geared to "people in the know." I saw more diagrams, timing charts, and electron microscope pictures of dram chips than I could ever shake a stick at.
