bank swizzle mode + DQS Training Control + memclock tri-stating

tyto polozky muzu nastavovat u pameti v BIOSu po stisku CTRL+F1, ale ani prez google jsem toho moc nedohledal (vsude se ptaji co to dela a nejake poradny vysvetleni co to vlastne dela nikde :)):

bank swizzle mode
zrovna k tomuto jsem zadne vysvetleni fuknce nenasel, ale vypada to, ze povoleni teto polozky pomaha nejvice :)

I got a easy question for ya , in your bios , the memory section, do you have a setting called "bank swizzle mode " ?
I do on the board I have now , I enalbed it and man my memory scored just hit the roof ! went from 2548 in memtest to 3248 ! awesome !

DQS Training Control
The DDR2 feature set also comprises off-chip driver calibration for the bidirectional differential Data I/O strobe (DQS). This calibration is often referred to as DQS training which happens on system initialization. The nForce5 chipset allows turning on or else skipping of this feature.

DQS will help get your ram a little more in sync. Its only needed at very high settings.

memclock tri-stating
A synchronous memory device that avoids erroneous output while internal initialization is taking place. In one embodiment, a tri-state logic circuit is used to selectively tri-state an output buffer during memory initialization.

a ted trochu praxe :)

1/ bank swizzle mode + memclock tri-stating = disabled, DQS Training Control = skip
Memtest 86+ (1.70) ukazuje propustnost 2895

2/ bank swizzle mode + memclock tri-stating = enabled, DQS Training Control = perform DQS
Memtest 86+ (1.70) propustnost 3235 :cool:
