4x1gig sticks and machine will not post


Recommended Posts

This is a plea for help.

 

In short, my machine will not post when all four sticks of OCZ Platinum Edition 1024MB 3200 memory (OCZ4002048ELDCPE-K) are inserted. With power, it beeps of memory errors -- of course, no display.

 

All sticks have been tested individually under memtest without any problems. I can run a pair together in dual mode with no problems. I cannot get all four to run simultaniously.

 

Some quick notes:

 

This was a machine running a single gig spread between two TwinX sticks. It was overclocked. Since that time, I've upgraded the bios to the 11/14/05 version, cleared the CMOS both the jumper, battery removal, and sitting without any power.

 

I'm really not certian what course to take at this point.

 

Thanks for your help!

Wow. Many thanks for the quick response!

 

Unfortunately, the problem persists.

 

Trying the advice of the optimized settings and using the 2-3-2-5 timings of the chip for the other properties, with CPC Disabled, the machine still would not post.

 

I've also utilized the detailed timings from OCZ:

 

FSB Bus Frequency............................. 200

LDT/FSB Frequency Ratio....................... Auto

CPU/FSB Frequency Ratio....................... Auto

PCI eXpress Frequency......................... 100

 

CPU Voltage .................................. Auto

LDT Voltage .................................. 1.20

ChipSet (NF4) Voltage ........................ 1.50

DRAM Voltage ................................. 2.60v

+0.03 if not 3.2V ............................ enable

 

Memclock (DRAM Frequency) .................... 200

1T/2T Timing (Command Per Clock).............. 1T

CAS Latency (Tcl)............................. 2T

RAS# to CAS# delay (Trcd)..................... 3T

Min RAS# active time (Tras)................... 8T

Row precharge time (Trp)...................... 2T

Row Cycle time (Trc).......................... 10T

Row refresh cyc time (Trfc)................... 16T

Row to Row delay (Trrd)....................... 3T

Write recovery time (Twr)..................... 3T

Write to Read delay (Twtr).................... 2T

Read to Write delay (Trwt).................... 3T

Refresh Period (Tref)......................... 3120

DRAM Bank Interleave.......................... Enabled

 

DQS Skew Control.............................. Auto

DQS Skew Value................................ 0

DRAM Drive Strength........................... Normal 3

DRAM Data Drive Strength...................... Level 1

Max Async Latency............................. 8ns

DRAM Response Time............................ Normal

Read Preamble Time............................ 6ns

IdleCycle Limit............................... 256

Dynamic Counter............................... Disable

R/W Queue Bypass.............................. 16x

Bypass Max.................................... 4x

32 Byte Granularity........................... Disable (4 Bursts)

 

And again, BIOS beeps of memory errors, only a single LED goes out -- and the computer is in limbo until I remove one set of sticks.

 

I would have expected to be able to enter the bios with a screwed up memory configuartion, but just have and inoperable machine as soon as it tried to execute some code. Any other ideas?

 

Again, many thanks for the help!

And regarding the system speed -- yes, I know the base machine would be slower with the 4gigs than with 2, but this is not a gaming machine and the memory is required for the application it will run. A loss of some performance is a gain when you don't have to swap constantly ;)

Maybe you're not listening very carefully as to what needs to be done.

First, I want you to clear your cmos. A simple move of the jumper with no power to the system (ie, turned off at the power supply). Make sure it's discharged to prevent any shorts.

Clear it for about 15 seconds, and I want you to ONLY use 1 stick of memory in the top orange slot, furthest from the CPU.

 

When you boot up, go into bios and set THESE exact settings.

 

FSB Bus Frequency............................. 200

LDT/FSB Frequency Ratio....................... Auto

CPU/FSB Frequency Ratio....................... Auto

PCI eXpress Frequency......................... 100

 

CPU Voltage .................................. Auto

LDT Voltage .................................. 1.20

ChipSet (NF4) Voltage ........................ 1.50

DRAM Voltage ................................. 2.80v

+0.03 if not 3.2V ............................ Disable

 

Memclock (DRAM Frequency) .................... Auto

1T/2T Timing (Command Per Clock).............. 2T (Disable)

CAS Latency (Tcl)............................. 2.5T

RAS# to CAS# delay (Trcd)..................... 4T

Min RAS# active time (Tras)................... 8T

Row precharge time (Trp)...................... 3T

Row Cycle time (Trc).......................... 8T

Row refresh cyc time (Trfc)................... 16T

Row to Row delay (Trrd)....................... 3T

Write recovery time (Twr)..................... 3T

Write to Read delay (Twtr).................... 2T

Read to Write delay (Trwt).................... 3T

Refresh Period (Tref)......................... 3120

DRAM Bank Interleave.......................... Enabled

 

DQS Skew Control.............................. Auto

DQS Skew Value................................ 0

DRAM Drive Strength........................... Auto

DRAM Data Drive Strength...................... Auto

Max Async Latency............................. Auto

DRAM Response Time............................ Normal

Read Preamble Time............................ Auto

IdleCycle Limit............................... 256

Dynamic Counter............................... Disable

R/W Queue Bypass.............................. 16x

Bypass Max.................................... 4x

32 Byte Granularity........................... Disable (4 Bursts)

I've actually followed the instructions as presented. When requested to put in only one stick, I threw it in slot one, not slot three. I cleared the CMOS. I entered in timings of 2-3-2-5, with CPC Disabled. That did not work.

 

I went through the same process, using the detailed timings from the OCZ site -- again, CMOS cleared, one stick in slot one. Used the OCZ timings as copied above, but with CPC disabled. No worky upon populating all four slots.

 

Attempted the latest advice. Cleared CMOS, put in a stick in slot three. Entered the exact timings as presented. Upon populating the other three rows, the machine would not post.

 

Tried the latest advice again, but with an extended power drain for CMOS clearing. Again, no worky.

 

:confused:

Any more ideas?

 

I have two LAN Party NF4 boards -- with different processor models. Same behavior in each. I also have a Dell Poweredge in the basement; its not the easiest machine to get to, but, of course, all four sticks were recognized and came up in dual channel mode without any problems.

 

Thanks

Hi, try placing two sticks in the orange slots and booting up. If that does not work, try them in the yellow slots if you have not already. I tried the 1 stick in each bank and never could get it working. I placed the other stick in (memory is matched pairs) and the system booted up.
