GeIL 2GB pc6400 with P5N?

I have 2gb GeILpc 6400 ULL.

What do i need to set my timings and voltages at?

Rig
E6600
Asus P5NE

Edit: There are advanced settings for the P5N below. It has been suggested these would need entering for the RAM to work. Who has this board and what did you set your timings to?

lol :p

Ok go into the BIOS.

If you go over to the advanced Tab, it should come up with a page called JumperFree Configuration. Go down to AI Tuning and select Manual, then go to Voltage Control and change the Memory Voltage to 1.9.

Now you need to find where the Memory timings are located, this i dont know, so just have a look around.
You need to get to a page that should look something like this:

Once your their set the timings as follows:

tCL (CAS Latency) to 4
tRCD to 4
tRP to 4
tRAS to 12
Command Per Clock (CMD) to 1

If you have any Memory related problems, up the voltage to 2.0 if that fails up it once again to 2.1 then 2.2 then 2.3, since 1.9-2.3 is what the manufacturer saids to put the voltage at 1.9 to 2.3.

I had a go at changing the timings.

Strange this strated to happen!

I kept getting prog error and the comp was freezing up sometimes!

Changed all settings back to AUTO for now and its all fine!
 
Does your BIOS have lots of timings for memory, a section for the 4-4-4-12 (example) bit at the top then a second section below that with tRRD, etc.? (as per example image in post above).

If so it seems with the Asus P5N boards you often can't leave those values on auto unfortunatly if you change the top settings... if this is the case your going to have to research the exact settings for your RAM... not easy...

Yes boss thats correct!


There was another section underneath with about 10 more settings!!

I just need to find someone with the knowledge :)

I am an total noob when it comes to RAm timings etc....only thing i know it the lower the better!
 
The problem is probably the 1T setting (Command Per Clock) - set that to 2T and it should be ok...

_IF_ you are happy with resetting the CMOS if things go haywire, want 1T timings (and have a bootdisc with memtest86+ on it - never boot into windows til your RAM has done atleast 3 OK passes of memtest)...

Then give these settings a whirl...

VDIMM: 2.1 (Might need more on some modules)

4
4
4
12
1

3
15
5
7
1
6
27
2.00nS

You might be able to tighten these up a bit later - but these should work...
