DRAM IDLE TIMER and other BIOS settings?
Trying to GOOGLE to find out just what some of the BIOS settings on my Asus
P4C800-E Deluxe mainboard do, but all I'm finding are overclocking stats... Basically, I'd like to find a site that explains the following in by BIOS: - DRAM burst length - DRAM idle timer - DRAM refresh rate - ICH Delayed Transaction - MPS Revision - How do CAS Latency, RAS Precharge, RAS-CAS delay and Precharge delay affect each other? Where are gains made with these settings? ....and finally, SMBus 2.0... what is it and should I move the jumpers on the mainboard to enable it? Any info or links would be appreciated! |

There is a thread on the overclockers website that explains some of them: http://tinyurl.com/2c22m I have the non deluxe version of the P4C800 and have disabled ICH delayed transaction, hasnt affected stability or anything so not sure what difference it makes.

Another place to find updated info is the free BIOS Optimization Guide at

ICH is the I/O Controller Hub inside the chipset. It is the interface
between the PCI bus and the cpu. I believe his ICH Delayed Transaction is the same as PCI Delay Transaction (PCI 2.1 compatibility). - Robert - "Lee" wrote in message ...

That's basically it. All the settings are explained in the bios guides at www.rojakpot.com and there are some good articles on memory compatability and "memory holy grail" settings at www.anandtech.com. |
