Gigabyte EP45 DS3L & F2-8500CL5D-4GBPK

[Harmakhis]

I'm having serious problems with my new package of DDR2 memory.

It's a F2-8500CL5D-4GPK on a Gigabyte EP45 DS3L (Bios vers. F10) with an Intel C2D E8600 @ 3,33 Ghz with Windows Vista Business SP2.

So now I get random BSODs. Mostly when just surfing on the web or doing some office work.

The last one displayed STOP 0x000000C2 (0x00000007, 0x0000110B, 0x00270001, 0x9E272948).

All the settings (timing etc.) seem to be in order. Any idea where the error might be?

[Tradesman]

Are your base timings, speed, DRAM voltage and command rate loaded manually? If on auto, load them manually (Command rate 2T, timings 5-5-5-15, voltage 2.1, speed 1066/533 (Depending on how shown)....also check tRFC, should be about 68...if still problems let us know along with NB voltage, CPU voltage

[Harmakhis]

All the values are loaded manually. Right now I can't look into CPU voltage etc. as I started the Windows Memory Diagnostic Tool (don't know the exact English name: German system - it's the one u can start during boot-up) and it's stuck at 45% like forever. The bad thing is that it already says that there are some hardware issues. So maybe the memory modules are faulty?

[Harmakhis]

Okay, I couldn't complete the test cycle with this windows tool... just restarted.

So the values in BIOS:

CPU Clock ration: 10x (manual)
CPU Host Frequency: 333 Mhz (auto)
System Memory Multiplier: 3.20B (manual)
Memory Frequency: 1066 Mhz (dependend on above)
CAS: 5 (manual)
tRCD 5 (manual)
tRP: 5 (manual)
tRAS: 15 (manual)
tRRD: 4 (on auto)
tWTR: 4 (on auto)
tWR: 13 (on auto)
tRFC: 68 (manual)
tRTP: 4 (on auto)
Command Rate (CMD): 2
CPU Vcore: 1.25 V (auto)
CPU Termination: 1.2 V (auto)
CPU PLL: 1.55 V (auto)
CPU Reference: 0.805 V (auto)
MCH Core: 1.1 V (auto)
MCH Reference: 0.76 V (auto)
ICH I/O: 1.55 V (auto)
DRAM Voltage: 2.1 V (on manual)

[Tradesman]

Believe I'd raise the vCore to 1.28-1.3 and the MCH Core to 1.2 maybe a bit higher

[Harmakhis]

Hmm... that didn't seem to help. Random restart during Windows Boot-Up. After that a BSOD saying something about possible faulty memory.

Could it be that the modules are just not working right and/or are defective?

[Tradesman]

Can run memtest on the sticks, individually , then if no errors, run memtest on both at same time. If you have sticks in slots 1-3 might also try it in 2-4

Set tWR 8, MCH Core 1.20V, otherwise everything look spot on.

Thank you
