What are your CPU, CPU NB, and memory multipliers set at?

Try a CPU Host Clock Control [Manual] x15 CPU multiplier. x14 CPU Northbridge Frequency multiplier. x6.66 memory multiplier. DCTs Mode [Unganged]

In DRAM Configurations, change DDR3 Timing Items to [Manual] and enter these numbers all the way down. 8-8-8-24-2-4-90ns-110ns-90ns-110ns-8-4-30-4

For Trfc0-3 for DIMM 1-4, try 110ns-127.5ns-110ns-127.5ns if the timings above don't work after voltage changes.

For voltages, change System Voltage Control to [Manual]. DRAM Voltage Control 1.65V. DDR VTT Voltage 1.0V. NB Voltage Control 1.2V. SB/HT Voltage Control 1.3V. NB PCIE Voltage Control 1.9V.

Let me know if it works after these changes. If not, let me know the results and I will be able to further assist you.

Thank you

What should the CPU NB VID Control be set to?
The settings I have right now are:
ACC EC FIrmware Selection= Hybrid
ACC = Auto
CPU Clock Ratio = x18
CPU Northbridge Freq = x12
CPU Host Clock COntrol = Manual
CPU Freq= 200 MHz
PCIE Clock= 167 MHZ
HT Link Freq= Auto
Memory clock = x8.00
DCTs Mode = Unganged
CAS#LAtency = 8T
RAS to CAS F/w delay= 8t
Row Precharge TIme = 8T
Minimum RAS Active Time = 24T
1T/2T Command Timing = 2T
TwTr Command Delay = 4T
Trfc0 for Dimm1 = 90ns
Trfc2 for Dimm2 = 110ns
Trfc1 for Dimm3 = 90ns
Trfc3 for Dimm4 = 110ns
Write Recovery Time= 8T
Precharge Time= 4T
Row Cycel Time= 30T
RAs to Ras Delay= 4T
CPU NB VID Control= Normal (Is this correct setting?)
CPU Voltage COntrol= +0.150v
DRAM voltage control= 1.640v
DDR VTT Voltage COntrol = 1.000V
NB Voltage Control= 1.200V
SB/HT Voltage control= 1.300V
NB PCIE Voltage Contrrol= 1.900V

Thanks in advance for the assistance!

CPU NB VID Control can stay at [Normal].

Are you trying to run DDR3-1333 or DDR3-1600? With your current settings it's for 1600, but the memory you purchased is 1333. With your current settings, you will need to change CPU Northbridge Freq. to x14 and memory clock at x6.66.

Let me know the results.

Thank you

I purchased DDR3 SDRAM DDR3 1333 (PC3 10666)... so ???

**GSKILL TECH** · 07-20-2009, 10:13 AM

So if you try to run it at DD3-1600 (PC3 12800), it's not going to work...

Make the changes I posted and it should work. Your numbers aren't adding up correctly, that might be why it's not stable.

First post you said it's showing as DDR3 937 or 967. Then you post your settings, and it's set at DDR3-1600.

Edit: Deleted some incorrect info.

**BiggJake** · 07-20-2009, 10:16 AM

Thanks.

Not sure what to do, really do not want to blow up the MB or processor.. maybe set everything to Auto in BIOS and then use the memory settings you specified..

**BiggJake** · 07-20-2009, 10:29 AM

4th core

Would running the 4th core limit my ability to have a stable system?

**GSKILL TECH** · 07-20-2009, 10:43 AM

If you are not sure what to do, then try the settings I suggested. Of course I will not give you OC settings where it could damage your CPU or mobo. Your main problem right now is the NB and DRAM frequencies not matching up correctly. If you simply change it to what I suggested then it would be working fine already.

Edit: deleted configurations because I was thinking of the wrong processor.

No, the 4th core will not change stability.

You need to change NB and DRAM frequencies though!

So here is what my choices are in some of the settings you want: marked with ****

ACC EC FIrmware Selection= Hybrid
ACC = Auto
CPU Clock Ratio = x15
CPU Northbridge Freq = x14
CPU Host Clock Control = Manual
CPU Freq= (only have a range between 200 and 500 MHz)******
PCIE Clock= 167 MHZ
HT Link Freq= Auto
Memory clock = (x4.00, x5.33, x6.66, x8.00)******
DCTs Mode = Unganged
CAS#LAtency = 8T
RAS to CAS F/w delay= 8t
Row Precharge TIme = 8T
Minimum RAS Active Time = 24T
1T/2T Command Timing = 2T
TwTr Command Delay = 4T
Trfc0 for Dimm1 = 90ns
Trfc2 for Dimm2 = 110ns
Trfc1 for Dimm3 = 90ns
Trfc3 for Dimm4 = 110ns
Write Recovery Time= 8T
Precharge Time= 4T
Row Cycel Time= 30T
RAs to Ras Delay= 4T
CPU NB VID Control= Normal
CPU Voltage COntrol= +0.150v
DRAM voltage control= 1.640v
DDR VTT Voltage COntrol = 1.000V
NB Voltage Control= 1.200V
SB/HT Voltage control= 1.300V
NB PCIE Voltage Contrrol= 1.900V

At these settings I am getting a "SYstem Voltage NOT optimized" flashing red in the BIOS..

Sorry about the "DDR3 937 or 967" I was trying to remember what it was saying when I wrote that from home.. the system was at the office. Please ignore that. Assume I started from scratch and want to optimize the system for best performance and saftey.

**BiggJake** · 07-20-2009, 11:09 AM

When running METEST86 v3.4 what should be reported? This is what mine shows..

Athlon 64 (0.13) 3013 MHz
L1 Cahe: 128 K 37206 MB/s
L2 Cache: 512 K 16378 MB/s
Memory : 4095 M 9818 MB/s
Chipset AMD k8 (ECC: Disabled)
Settings: RAM: 502 MHz (DDR100) /CAS: 1-3-1 /DDR-1 (128 bits)

BIOS reports DDR3-1333

**GSKILL TECH** · 07-20-2009, 11:35 AM

The memtest86 speeds are good. The only thing that is weird is the "Settings: RAM: 502 MHz (DDR100) /CAS: 1-3-1 /DDR-1 (128 bits)"

Try a diff memtest?

Regarding CPU Freq, sorry I was thinking of a diff processor for some reason.. So keep the CPU freq. at 200. Set memory clock to x6.66.

For voltages, change to these if you won't be OCing much:
CPU NB VID Control= Normal
CPU Voltage Control= Normal
DRAM voltage control= 1.60v
DDR VTT Voltage COntrol = 1.000V
NB Voltage Control= 1.200V
SB/HT Voltage control= 1.300V
NB PCIE Voltage Contrrol= 1.900V

Save and exit and everything should FINALLY be OK now. =) Try the same memtest, if still the same weird settings, try a diff version.

**BiggJake** · 07-20-2009, 12:20 PM

Settings right now..

ACC EC Firmware Selection= Hybrid
ACC = Auto
CPU Clock Ratio = x15
CPU Northbridge Freq = x11
CPU Host Clock Control = Auto
CPU freq (MHz = 200 (system auto selected)
PCIE Clock= Auto
HT Link Freq= Auto
Memory clock = x6.66
DCTs Mode = Unganged
CAS#Latency = 8T
RAS to CAS F/w delay= 8t
Row Precharge TIme = 8T
Minimum RAS Active Time = 24T
1T/2T Command Timing = 2T
TwTr Command Delay = 4T
Trfc0 for Dimm1 = 90ns (should this be 110ns)****
Trfc2 for Dimm2 = 110ns (should this be 90ns) ****
Trfc1 for Dimm3 = 90ns (should this be 110ns)****
Trfc3 for Dimm4 = 110ns (should this be 90ns) ****
Write Recovery Time= 8T
Precharge Time= 4T
Row Cycel Time= 30T
RAs to Ras Delay= 4T
CPU NB VID Control= Normal
CPU Voltage Control= Normal
DRAM voltage control= 1.600v
DDR VTT Voltage COntrol = 1.000V
NB Voltage Control= 1.200V
SB/HT Voltage control= 1.300V
NB PCIE Voltage Control= 1.900V

Only get the red flashing "System Voltage NOT optimized" message. When both the CPU Host Clock Control and System Voltage control are set to manual. Having either one to Auto makes it stop.

I also can't push beyond the CPU NB Freq of x11.. won't load system when set above that.

BTW, read that there is an issue with MEMTEST86 v3.5 and 4 GB of Ram, the rebooting issue occurs.

**BiggJake** · 07-20-2009, 12:26 PM

What DRAM Frequency should be showing for the memory in CPU-Z program..?

**GSKILL TECH** · 07-20-2009, 12:27 PM

As long as mobo can detect correct settings, AUTO is OK, like the CPU freq.

For...
Trfc0 for Dimm1 = 90ns (should this be 110ns)****
Trfc2 for Dimm2 = 110ns (should this be 90ns) ****
Trfc1 for Dimm3 = 90ns (should this be 110ns)****
Trfc3 for Dimm4 = 110ns (should this be 90ns) ****

It is correct, but maybe too tight and causing instability. Try 110ns, 127ns, 110ns, 127ns.

With your new posted settings, is it still unstable?
