Guys i have a config of::
Athlon64 3000+
ASUS A8N SLI Prem
Hynex HY5DU121622CTP-D43 DDR400 512MBx2 RAM
XFX 6600GT 256MB PCIe
Segate 7.2K Barracuda 160GBx2 on Silicon RAID0
Odyssey-JULY05 500w 20PIN ATX PSU


Below is a list of the exact DRAM config page from my MObos BIOS setup.
I want to know the exact meaning of each of the following items.

DRAM Configuration

ITEM RANGE DEFAULT(for my RAM)
Memclock index value (Mhz) 200-600 400
CAS# latency (Tcl) 2,2.5,3 3
Min RAS# ative time(Tras) 5T-15T 8T
RAS# to CAS# delay(Trcd) 2T-7T 4T
Row Percharge Time(Trp) 2T-7T 4T
Row cycle time(Trc) 7T-22T 11T
Row refresh cyc time(Trfc) 9T-24T 14T
Read-to-Write time(Trwt) 1T-6T 5T
Write Recovery time(Twr) 2T,3T 3T
1T/2T Memory Timing 1T,2T 2T

Also i want to know how to identify the above values for RAM Modules without plugging them in (the default values) either from the model no. or any other info.

Then finally i want to know how to correctly overclock by modifying the above values.

If u could point me to some literature in the net then it would be fine too.

I am familier with CPU overclocking.

Is my RAM any good? and if not how and which RAM to buy (should not be too costly)
The above ram i bought for 2500Rs each, 20 days ago along with all the above mentioned hardware.

Thankx in advance...(Anyways how to be put in tabs in this post???)

I am not sure what you expect, but if u want to set the default values from the spd, just set the ram timings to auto.
