2-2-2-5-1t

[Aino]

I also have an Asus A8N-SLi Deluxe and the TWINX1024-3200XLPRO, XMS3200, 1024MB, 2x184 DIMM, with funky LEDs and all.

 

I want to set it to 2-2-2-5-1T because it is supposed to be able to, it is the reason why I got them, only I am not able to because I have no idea how. :biggrin:

 

My system:

Antec Lanparty case

Tagan TG530-U22 (530W)

Asus A8N-SLI Deluxe

Athlon 64 Processor +3700

Zalman CNPS7000B-AICu LED

2x Asus Nvidia Extreme N6600GT 128MB

2x Western Digital raptor 68GB STRIPE

and of course 2x 512MB, TWINX1024-3200XLPRO

 

I was hoping Plug-n-frag was going to automatically optimise my ram for me, but when I check in my BIOS i see the following settings:

 

Timing Mode AUTO

Memclock index value 400 Mhz

CAS# latency (Tcl) 2.5

Min RAS# active time (Tras) 5T

RAS# to CAS# delay (Trcd) 3T

Row precharge time (Trp) 3T

Row cycle time (Trc) 11T

Row refresh cyc time (Trfc) 14T

Read-to-write time (Trwt) 4T

Write recovery time (Twr) 3T

1T/2T Memory Timing 2T

S/W DRAM Over 4GB Remapping Disabled

H/W DRAM Over 4GB Remapping Disabled

 

:eek:

 

Ehm looks far from 2-2-2-5-1T to me :roll:

 

What does the 1st "2" of 2-2-2-5-1T stand for? I presume CAS# latency?

And the 2nd "2"? and so on?

 

I have put my DDR voltage to 2.8 volts, it was 1st on AUTO, but with no change to performance it seems.

 

Could you please advise me what settings I shoud change?

 

Thanks :cool:

Please follow the link in my signature for the tested settings and just load setup defaults and then set the memory voltage to 2.75 Volts and set the tested settings manually!

Try these settings:

 

Timing Mode: Manual

 

Memclock index value: 400 mhz

Cas latency (TCL) : 2

Min ras active time (TRAS) : 5

Ras to Cas delay (TRCD) : 2

Row precharge time (TRP) : 2

Row Cycle time (TRC) : 16

Row refresh cycle time (TRFC) :22

Read-to-write time (TRWT) : 3

Write recovery time (TWR) : 3

1T/2T memory timing : 2

S/W Dram over 4gb remapping : Disabled

H/W Dram over 4gb remapping : Disabled

 

Hyper transport frequency : 5

Amd K8 Cool'nQuiet : Enabled

 

Jumperfree Configuration:

Overclock profile: Manual

CPU frequency : 200

PCI Express : 100mhz

DDR voltage : 2.7

Chipset voltage : 1.6

HT voltage : 1.25

CPU multiplier : 11

CPU voltage : 1.550

PCI clock syncronization mode : 33.33mhz

 

Test your system for stablity. Use Prime95:

Test for stability for ~8 hours. You can use the computer while you test but I advise not using system intensive tasks such as rendering video, burning cd/dvd's or gaming.

 

If you are stable at this setting then I advise you to enter your BIOS and set:

 

1T/2T memory timing : 2

from 2 to 1 and retest once more. If you are stable at these settings and 1T, then you are good for the go.
