I was really confused like I said the math worked out where I could get 1600 at all 4 timmings on my P5E64 WS EVOLUTION and E8400. I can litterally run all the latches wtih no noticable difference at all and they are all stable. There was only a slight increase in read speed or one of the 3 memory speeds the rest was virtually identical.

Must be differt on Gigabyte EP45-UD3P cause im running fsb of 486 and a 333 strap i just checked.

The latch basically controls the FSB : DRAM ratio. If it s a 400 2.00 latch w/ 400 FSB then it would multiply your 400 FSB by 2 and give you 800. Which would give you your ram speed. Or something like that


Also keep in mind that an Intel FSP is quad pumped (meaning you take the FSB you set on your CPU and multiply it by 4 which gives you your FSB speed).

Actually latch is not FSB : DRAM ratio. That's what SPD is. 2.00 = 1:1 ratio which is what I want but there's two types of 2.00. One that works at 333mhz and one that works at 400mhz. But I'm actually running 475mhz which is why I was asking about which would be better.

Yeah, on the DS3R I can't boot 399 with 400strap and can't boot 400 with the 333 strap.

Download everest or a memory benchmarking tool and check both for an increase. That is the only real way to check for any increase in performance like I said once you are into winidows there is to actual way or program that will tell you you have 333 mch latch. Also there is no actual formula or quantative value where the mch latch fits in. Its an internal NB deal that is still a little confusing to me sometimes. I really dont like the gigabyte way of doing it A,B,C,D etc. But now I know what it is its not really important as long as you are stable and nowadays everyone is going to use 333 or 400 basically.

But like I said I am at 4GHZ on an E8400 and 1600 7-7-6-18 on my mushkins I can still boot up and pass every stress test with 200,266,333,and 400 MCH latch. The match works out so I can still have 1600 on all 4 so I tried it, leading to more of my confusion when they all worked.

If you run 1:1 you should use Latch 400 then you can go one "Static Read Value" (Performance Level, tRD) step lower then with Latch 333.

About the same bandwidth but lower latency.
