Memory frequency in CPU-Z question

[TheProfiler]

When I look under memory tab in CPU-Z 1.39, it says 333 mhz.
I have DDR2 667 MHz modules.
So this is correct, right? It's double-data-rate thingy? Or should I see 667 MHz there?

Thanks. I lowered CAs latency from 5 to 4 and it's stable. Should I try to lower those other numbers? Like, now it's 5-6-4-4-12 or something. Maybe to lower them all by 1? Hmmmm?
I have Kingmax memory, not the best in the world, I know. I also raised voltage from 1.9 to 2.0.

Will do. What's that 2T thing? Should I set it to 1T?

Try setting to 1T at stock speeds. If still stable at 2.0v and 1T timings, slowly start tightening the other timings, starting with the first one. Drop it by 1, move to the next, and so on, testing for stability in between.

I fiddled with memory a bit yesterday....
I left it at 2T, raised voltage from 1.90 to 2.0
Default timings were: 5-6-5-15-21, lowered to
4-5-5-13-19, all stable for now, ran Memtest for 20mins, didn't have time for more. No errors. So, I should go for 1T?
What's the difference?
How much lower you guys think I can go?

From what ive seen on the net 1t is better performance for the memory than 2t... sorry I dont have links to this 🙁

Seems like I'm getting 2-4% better performance with 1T but I also get a lot of CTD's and blue screens...
