Notes: I am not an overclocker. I use all listed hardware at stock/default settings. I update all my drivers religiously, I am kinda OCD about it.

Situation:

I have been fighting random restarts for quite awhile now and have tried numerous fixes to no avail. Today I stumbled across info regarding the need to increase the North Bridge voltage when using (2) 4 gig kits.

Question 1: The bios of my DP45SG allow me adjust the voltages but for both MCH/ICH not just MCH, can I change it anyway? Most things I have read said NEVER change the ICH voltage.

Question 2: Are there any memory timing settings that I will also need to adjust? I am using stock speeds of 9-9-9-24

Question 4: DRAM voltage is on auto at the moment, should I manually set it? should it be increased?

Question 5: Am I missing anything?

Thank you in advance for any advice.

1. It would be fine, but in your particular case, you should not have to raise MCH right now.

2. 9-9-9-24 should be fine.

4. Try 1.550V or 1.60V to see if that can improve stability.

5. Make sure each kit is in the same color slots. Since you are attempting two separate kits, it is necessary to make sure they are in their respective dual channel slots. That is your best chance at compatibility.

Thank you

Thank you for the quick reply.

1) I have ensured the matched sets are together via the batch number listed on their tags

2) I manually increased the DRAM voltage to 1.55v to start, if I get any restarts after reboot I will try 1.6v before I do anything else.


If I were going to increase the MCH, should I go directly to 1.4v or step it up by .05? Also, what would be the min/max for tRFC with the default being 48?

again, thank you for the assistance.

UPDATE:

1.55v froze up within 10 minutes of rebooting and 1.6v lasted about an hour.

Check that you have the latest BIOS, if not upgrade that first and try. What is your FSB, could try raising it a hair along with the vCore (CPU voltage) a bit. Think you'll want about 88 for tRFC for 4 sticks....if still no joy try the MCH/ICH up by 0.05

[Tiny4409]

Bios are up to date per Intel.

FSB voltage was default so I increased it to +0.1

MCH/ICH was 1.1 now 1.15

tRFC was 48 now 88

Memory Voltage is left at 1.6v

I will report back.

We'll be waiting to hear
