custom timings for Twinx-2048 (3200C2)

[micro]

Here is list of my custom timings for Corsair TwinX-2048 3200C2 modules, maybe it will help to other users of same kind of modules, I use latest official BIOS for my DFI LanParty NF4 SLI-DR:

 

Command per clock (CPC)- Enable (1T)

CAS Latency Control (Tcl)- 2.0

RAS# to CAS# delay (Trcd)- 03

Min RAS# active time (Tras)- 06

Row precharge time (Trp)- 03

Row cycle time (Trc)- 07

Row refresh cycle time (Trfc)- 10

Row to row delay (Trrd)- 00

Write recovery time (Twr)- 02

Write to read time (Twtr)- 01

Read to write delay (Trwt)- 01

Refresh period (Tref)- 3072

Odd divisor correct- Disable

Dram Bank interleave- Enable

DQS Sqew Control- Increase sqew

DQS Sqew value- 255

DRAM Drive strength- Auto

DRAM Data drive strength- Auto

Max Async latency- 05 (Auto is not bad option here)

Dram response time- Fastest

Read preamble time- 02 (Auto is not bad option here)

Idle cycle limit- 064

Dynamic Counter- Enable

R/W Queue Bypass- 16x

Bypass Max- 07x

32 byte Granularity- Disable (4bursts)

 

in memtest v1.65 (from DFI lanparty bios) I get 2825 MB/s. This value is changing if I use different refresh period(Tref):

Tref:

3120=2825 MB/s

0064=2432

1560=2719

0032=2142

0780=2719

0016=1239

3072=2825

0128-2437

 

In EVEREST home edition v2.20.405 I get these results:

Mem read:5121 MB/s 10th place

Mem write:2245 MB/s 5th place

Mem latency:47.0 ns 2nd place

 

All respect goes to THE DEFINITIVE
