DDR2 memory config help please

ZoSoSwiM · 02-17-2012, 06:30 AM

I recently upgraded my system from XP pro32 to Windows 7 x64. I also purchased some new RAM for my machine going from 2gb Corsair Dominator to 8gb of Gskill F2-8500CL5D with 4x2gb sticks.

System info:
Intel Core 2 Duo E8500
Codename Wolfdale
Specification Intel(R) Core(TM)2 Duo CPU E8500 @ 3.16GHz
Package (platform ID) Socket 775 LGA (0x0)
CPUID 6.7.6
Extended CPUID 6.17
Core Stepping C0
Technology 45 nm
TDP Limit 65 Watts
Core Speed 1999.9 MHz
Multiplier x FSB 6.0 x 333.3 MHz
Rated Bus speed 1333.3 MHz
Stock frequency 3166 MHz
Northbridge NVIDIA nForce 650i SLI SPP rev. A2
Southbridge NVIDIA nForce 650i SLI MCP rev. A3

Running with 2x2gb sticks set as so my computer runs fine..
SMBus address 0x52
Max bandwidth PC2-6400 (400 MHz)
Part number F2-8500CL5-2GBPI-B
Number of banks 2
Data width 64 bits
Correction None
Nominal Voltage 1.80 Volts
EPP yes (1 profiles)
XMP no
JEDEC timings table CL-tRCD-tRP-tRAS-tRC @ frequency
JEDEC #1 4.0-4-4-10-16 @ 266 MHz
JEDEC #2 5.0-5-5-15-24 @ 400 MHz
EPP timings table CL-tRCD-tRP-tRAS-tRC-CR @ frequency (voltage)
EPP profile #1 (full) 5.0-5-5-15-48-2T @ 533 MHz (2.100 Volts)

When I put the 2 other sticks in the machine simply sits at a black screen. If I pull the sticks it boots fine. I've tested the sticks and all 4 are in good shape. I've tested the slots as well.

Anyone have any ideas to help me get this running with all 8gb?
I'm just looking for a stable system here nothing over the top.

Thanks!!

What motherboard are you using? Maybe does not support 8GB of ram, for example my old motherboard with 775 socket supports only up to 6GB ram via dual channel.

It's a Dell XPS 630i with an nVidia 650i mobo.. It's supposed to be able to support the full 8 gigs.

Try increasing the RAM voltage in the bios with only 2 ticks to 2.1v

Shutdown then add the remaining RAM and see what happens.

It may very well support 8GB total RAM, but like alot of NForce 650 boards, it might not allow the full speed in ALL DIMMs. I've seen this on quite a few boards where the fastest supported speed was only allowed in 2 out of the 4 DIMMs. Usually motherboard makers have a BIOS update for this issue.

Install your old RAM, or just 2 DIMMs of your new RAM, which ever works well ATM. Then update to the latest available BIOS version, which for your Dell system is v1.0.13 (5/19/2009)

After this is completed, try populating all 4 DIMMs with your new RAM. Your RAM seems to support 533 (1067Mhz) but your board only supports up to 400 (800Mhz), so please be aware of that.

Well.. I re-updated my bios and then manually set the clocks to 800. I installed the extra ram after that. Happy to say my computer booted right up with no problem. It's currently running well so we shall see if I have any trouble. Thanks for the help!
