Settings for F3-10666CL9D-4GBRL and GA P55-UD3

[Parampi]

When I got this computer with 2 sticks, I had a stable machine. But recently I bought 2 additionnal sticks, increasing to 8gb. I could use the computer during few days before having BSODs, then when I go back to 2 sticks there is no problem anymore.
I have run memtest during couple of hours without having any problems.

How should I configure the bios to get a stable computer?

Model of the motherboard: GA P55-UD3 (bios version : f4l)
Model of the memory: F3-10666CL9D-4GBRL (4*2Go)
Model of the CPU: intel i5 750

With the extra sticks you'll have to raise your tRFC to around 195 (if in NS, if in clicks may need to go about 88)

[Parampi]

After raise my tRFC to around 88, I could use without any problems my comp during few days until now. I had 2 BSODs type Memory_management and PFN_List_Corrupt and froze twice on windows, unable to do anything but reboot manually.
How could I fix that?

[Tradesman]

Raise your vCore just a hair (maybe .05), and drop tRFC to 86

Tested yesterday (european time) without any problem but today had a BSOD on the first boot of the day, after shutting the computer off during around 15 hours.
How can I fix it?

please try to raise the cpu vtt voltage a little to 1.3v
the loading of memory controller is much heavier while running with 4 sticks installed, so you may need to raise the voltage to the memory controller to improve the stability
thanks

During few days, I just used 2 sticks (waiting for a more mature bios to use the 4 sticks) but even with two I had BSODs today type Memory_manager with both default(auto) or custom BIOS settings.
I don't know what to do now, memtest gave me no error.

Hello Mr Administrator,
I got the same motherboard, CPU and RAM, but just 2 sticks.
Should i use the same settings you recommend, even if i got 2 sticks?
Thank you

[Siegel]

i didn t say it, but of course i got the same problem..

[GSKILL TECH]

Use the same settings, except you will not need to change the QPI Voltage. Once everything is set, your computer should be running smoothly.

Thank you

I did it but my computer didn t run smoothly...
I updated my bios to f5 and it seemes ok now.

[Siegel]

my pc seemed ok, but it wasn't !
Sorry it was too early for talk.

Nevertheless wth the settings you provide and F5 bios, it really seems better. We will see in a few days.

I didn t change CPU Multi Threading and Extreme Memory Profile (X.M.P) settings, because i didn t find them in F5 bios.

Thank you

[Siegel]

After being shut down during 1 hour my pc could reboot without problem.
After a whole night, he cant.

May I have others settigns to fix this problem?

Thank you

[G.SKILL]

we don't think it could be solved by some setting
would you like to try one stick at one time?
thanks
