F2-8500CL5D-4GBPK x2 & Foxconn A7DA-S

[goatgonads]

I just installed F2-8500CL5D-4GBPK x2 in a Foxconn A7DA-S, updated my bios. Based on what info I could find for other Foxconn users, attempted to run at:

Command Rate: 2T
Cas Latency: 5
TRCD: 5
TRP: 5
TRAS: 15
TRC: Auto
TWR: 13
TRRD: 4
TWTR: 4
TRFC0: 195ns
TRFC1: 195ns

Ram Voltage 1.9
Every other setting on MOBO put at default

Bluescreen when loading windows. Tried to increase CPU and NB volts by +.075 but made no difference.

Ram runs stable at auto detect speeds of 400mhz with stock settings, but I would like to run at advertised speeds.

System Specs:
Foxconn A7DA-S
Phenom 2 x4 940
4x2GB F2-8500CL5D
ATI 5870
Alienware 1KW PSU

[GSKILL TECH]

TWR: 10
DRAM Voltage 2.10V

If that does not work, try these settings. They should actually be faster than DDR2-1066 CL5.

Command Rate: 2T
Cas Latency: 4
TRCD: 4
TRP: 4
TRAS: 12
TRC: Auto
TWR: 8
TRRD: 4
TWTR: 4
TRFC0: 195ns
TRFC1: 195ns

Ram Voltage 2.0

Thank you

Further Information

I am unable to set it to those settings because some of them are not available, let me show you what I have available:

Bios Version: 81BF1P09

Command Rate: 1 or 2T
Cas Latency: 3 thru 7
TRCD: 5 thru 12
TRP: 5 thru 12
TRTP: 2-4 or 2-5
TRAS: 15 thru 30
TRC: 12 thru 42
TWR: 5, 6, or 8
TRRD: 4 thru 7
TWTR: 4 thru 7
TRFC0: 75, 105, 127.5, 195, or 327.5
TRFC1: same as above

Memory Hole Remapping: yes/no
DCT Unganged mode: auto=ganged, always=unganged
Power down enable: enable/disable
Power down mode: channel, or chip select

Memory speed mode: Auto/Limit/Manual
Memory speed adjust (if not using auto): 200mhz thru 533 mhz

voltage is only adjustable +/- 50mV increments, so the closest that I could come to 2.1V was either 2.128 or 2.078

If there are any additional settings such as spread spectrum or advanced clock calibration that may need to be adjusted or affect performance, let me know.

Here are the best settings for your system:

Command Rate: 1T
Cas Latency: 4
TRCD: 5
TRP: 5
TRAS: 15
TWR: 6
TRFC0: 127.5
TRFC2: 127.5
TRFC1: 127.5
TRFC3: 127.5

Memory Hole Remapping: yes
DCT Unganged mode: always=unganged
Power down enable: disable

Memory speed mode: Manual
Memory speed adjust: 400mhz

So it will not run at advertised speeds? Also, there are some unspecified settings, including voltage, what are they to be set at?

[Tradesman]

Might try

Command Rate: 2T
Cas Latency: 5
TRCD: 5
TRP: 5
TRAS: 15
TRC: Auto
TWR: 13
TRRD: 4
TWTR: 4
TRFC0: 195ns
TRFC1: 195ns

Then OC your CPU and add voltage to the CPU/MC, the MC in the 940 needs a little extra to push 8 GB, depending on the individual board may not be able to hit the full 1066, though should go at least 900-1000 - it's not the RAM it's those AMD CPUs that are weak on the MC and the mobos that have trouble integrating with the AMD MC

The Foxconn A7DA-S has no IMC voltage control in the BIOS.
