Hello,

F2-8500CL5D-2GBPK
BIOSTAR TA790GXE 128M
AMD Athlon II X4 620 Propus 2.6GHz 4 x 512KB L2 Cache Socket AM3 95W Processor
Antec Earthwatts 430 watts

I built a new rig and cannot get the memory stable. I am getting BSOD, random restarts and freezing in Windows XP. I might have bad sticks cause even if I manually set the settings or auto it fails memtest86+ on test 5 & 6.

Below are my current settings:

VOLTAGE CONFIGURATION

CPU Over Voltage [START-UP]
Memory Over Voltage [2.10V]
Chipset Over Voltage [1.20V]
HT Over Voltage [1.20V]
Side Port Voltage [1.80V]

MEMORY CONFIGURATION

Memory Clock Mode [MANUAL]
Memclock Value [DDR2-1066]
DRAM Timing Mode [DCT 0]
CAS Latency (CL) [5 CLK]
2T Command [2T]
TRCD [5 CLK]
TRP [5 CLK]
tRTP [3-5 CLK]
TRAS [15 CLK]
TRC [24 CLK]
tWR [8 CLK]
TRRD [4 CLK]
tWTR [4 CLK]
tRFC0 [127.5ns]
tRFC1 [127.5ns]
tRFC2 [127.5ns]
tRFC3 [127.5ns]

Please let me know if my settings are off. Thanks in advance and I appreciate the help.

Might lower tRFC to next setting down

Thanks for the response Tradesman!

Would this be 105ns or 195ns?

[GSKILL TECH]

Try the following settings:

CPU Over Voltage [START-UP]
Memory Over Voltage [2.10V]
Chipset Over Voltage [1.20V]
HT Over Voltage [1.30V]
Side Port Voltage [1.80V]

MEMORY CONFIGURATION

Memory Clock Mode [MANUAL]
Memclock Value [DDR2-1066]
DRAM Timing Mode [Both]
CAS Latency (CL) [5 CLK]
2T Command [2T]
TRCD [5 CLK]
TRP [5 CLK]
tRTP [3-5 CLK]
TRAS [15 CLK]
TRC [30 CLK]
tWR [8 CLK]
TRRD [4 CLK]
tWTR [4 CLK]
tRFC0 [127.5ns] if no go, try 195ns for all 4.
tRFC1 [127.5ns]
tRFC2 [127.5ns]
tRFC3 [127.5ns]

Thank you

For 2GB I'd try 105

[loyah1]

I tried it with 105ns and 195ns and still errors out at test # 5 & 6 in memtest86+ 2.10. But, in memtest the settings are 433(866) CAS 0-5-1 / DDR 1 (128 bits), does this make a difference if it does not recognize the RAM correctly?

Any other suggestions?

[Tradesman]

It can, yes, memtest is designed for the x86 architecture, you could try a different version or two.
