Sorry, I was in a rush the other day and didn't take my time to explain fully!!
If you Look at your RAM visually you can tell how many Banks it has, as SDRAM is only configured into Modules of either 2 or 4 Banks!
Single-sided SDRAM has 2banks of chips with 4 chips in each bank! So to be able to use a setting of 4Bank you would need a mininum of 2-sticks Single-sided !! If you only have 1-stick of Single-sided SDRAM the only setting availabe should be 2Bank!
Double-sided SDRAM has 4Banks of chips with 4 chips in each bank! So your setting should always be set to 4Bank!!
Its just come to my attention that the NF2 MOBOS ARE CONFIGURED WRONGLY...
under normal conditions setting ram two 22.214.171.124 woud be good and run very fast, this is not so..you may wish to check your mobo just incase this is the same on your system as its some thing we dont often check..
Try these setting as i have been doing some testing to find the best read and write results for the mobo.
T RP 3
something like this
Cycle Time (tCYC) = 6.000 ns fMax = 166.667 Mhz
Access Time (tAC) = 0.700 ns fMax = 1428.571 MHz
CS Supported: 0.0 clocks
WE Supported: 1.0 clocks
Min Delay, Bk/Bk Random Cols: 1 clocks
Min Row Precharge Time (tRP): 18.000 ns
Min Row Active delay (tRRD): 12.000 ns
Min RAS to CAS delay (tRCD): 18.000 ns
Min Actv to Precharge (tRAS): 42.000 ns
Addr/Cmd Setup Time: 0.800 ns
Addr/Cmd Hold Time: 0.800 ns
Data Setup Time: 0.450 ns
Data Hold Time: 0.450 ns
Its not going into detail as there never is a definative guilde as to what does what and where thing should go.
you need to have a good techinical mind to work out this lot, and you need to be able to get technical details from the makers of your RAM, - Thats even worse, Have you read the tech white papers? with there little diagrams!
Im lucky cuz I have been a engineer so knowing things like conductive fault tollerences and other stuff that you would NEVER ever use I know...
Anyway I hope this exsplains things a bit better.
When changin your timing Remember TRCD and tRP Must match. TRAS is anywhere from 3 -11 dependent of the speeds of your ram and preformance. Download sisoftsandra and run the benches on RAM, change a number and see what you get..
Ex Standard DDR 333 in a NF2 gave me 2336, Clocked in the NF4 gives me 4894 as you can see this is a considerable difference, but ther was never the oppertunity with the NF2 board to do this..
I was playing around with my memory the other day, got it to 258MHz at 2.8v and broke the 4,000mb/s barrier (actual performance), not bad from bog standard Crucial PC3200 and a nice a64 memory controller and a Via K8T800 Pro chipset with AGP/PCI lock.
I didnt realise people were still reading this, I posted it some time ago, Writing something about ram is hard becuase each ram make and model is different and so is the mobo that is used when you clock or want to adjust.
4000MB/s isnt so good for what you have, I have some OCZ basic that pulling over 6100MBs I think that maybe there is somthing worng there somewhere as the board that you have should be hitting atleast 5K im only running :@ 204FSB to get my speeds, I would consider adjusting your times to check for available bandwidth and speed.
