Tref values

[Jomiy]

Wow I'm gonna try this now!

Okay in simple terms:

Everest refresh rate*FSB = Tref cycles

i.e.
7.8*200 = 1560
7.8*300 = 2457

I'm gonna try it and report back tomorrow.....

Okay, let me see if I understood it correct. So, if my FSB/HTT is 250, it'll then be 250*7.8=1950, and the closet TREF values to that without going over is: 2064(133Mhz-15.6us&1.95us). That's it? I still don't get. Man, am I so dumb or what?!!! I just don't get how these numbers/values work.

So thats the formula we use? We find the refresh rate in Everest and then just multiply that by the FSB/HTT speed to get the TREF value we should use?

no

lookup your HTT/Mem speed in the table. (or take a value close)

I looked it up in the table and came up with the same TREF value i got calculating my refresh rate times HTT speed.

I'm running 280Mhz with OCZ PC3200 Platinum Rev2 and the refresh rate in Everest is 7.8 us so 7.8 x 280 = 2184 and the next highest TREF value from that is 2336.

I'll try it out later and see if it helps stability any. Right now i'm not stable running 1:1 at 280Mhz 1T with this stupid Venice core. My Venice will overclock to 2.8Ghz+ but its memory controller seems crappy.

I'll share a few of my questions and thoughts on this.

First 1.95us, 3.9us, 7.8us, 15.6us is it that if these are lower the memory will run more stable?????????

Does memory size effect this setting???????

How does command rate affect tref??????

Also I believe once you figure out the refresh time you want to run at you complete this equation [refresh time in us]/[1/fsb] and then select what ever tref is closest to that number.

What do you think???? Is this right?
