Overclocking mobo G41M-VS3 in order to make ddr3 work. How to change the frequency

[deielectus]

Hello! Does anybody know how to make a ddr3 fsb 1333Mhz work for a mobo G41M-VS3 FSB 800MHZ. It supports dual channel.

If the Bios do not have the option to set it to 1333 then you will need to set the ram to 1066, then adjust the FSB to 233. this will set the ram to 1333. you may have to lower the CPU multiplier and the NB frequency back down to stay stable.

Thanks, bgunner. Well, Actually the mobo specs said: FSB1333; DDR3 1333 Dual Channel. I did buy a couple of ddr3 fsb1333MHz but when I put them nothing seems to happen. I tried adjusting the jumpers on the mobo but doesn't work either. Finally I tried setting the bios without any luck. What is NB frequency? Should I adjust the CPU frequency to 233? How can I know if my mobo has the option to set the ram freq to 1333?

NB frequency is "North Bridge" frequency.

IN bios under OC tweek the very top selection is Dram Frequency. this is the speed setting for the ram. try this and see if it will allow you to set it to 1333.

EDIT: the cpu you have will tell you if you can run 1333. the setting you need may be the labeled as 667.

That is the System Bus. 1333MHz. I do not quite understand what your trying to OC...I am pretty sure that the G41 only support DDR3 frequency of 1066MHz.

Ok, I'll try it as soon as I got home. I'll Let you how everything was comming along..

have a look at this. The board will support the 1333 MHz ram. It just depends on if the CPU can handle the 1333 speed.

This are the values that appear in the BIOS:
DRAM Frequency: 667Mhz DDR3_1333
DRAM Command Rate: 1N
>DRAM Timming Configuration

Ratio CMOS Setting: [15]
Intel(R) SpeedStep(tm) tech: Auto
Overclock Mode: Manual
CPU Frequency(MHz):333
PCIE Frequency (MHz):100
DRAM voltage: auto
NB voltage: auto
VTT voltage. auto
GTLRef voltage: auto

I tried the values above but this didn't work....Am I missing Anything?

What CPU are you running? Obviously it is an Intel Core 2 CPU but which one? Core 2 duo, Core 2 Quad, Core 2 extreme and what model number?

Hello bgunner,

It is a Pentium Dual Core E5700 3.00Ghz.

What CPU are you running? Obviously it is an Intel Core 2 CPU but which one? Core 2 duo, Core 2 Quad, Core 2 extreme and what model number?

OK because this is an older system the memory controller is on the board itself and not in the CPU. This means that either the ram can not run at 1333MHz or the Ram is not very compatible with the memory controller or the memory, memory controller and /or the north bridge may need more voltage.

lets start with making sure the Ram modules are compatible. To do this you need teh exact model number of the ram you have. Once you know this you need to go to AsRocks web page for your board and look in the memory QVL for your ram model numbers. QVL = Qualified Vender List. In this era of motherboards the Ram compatibility was a major issue so lets make sure your not having an issue here first.

next we want to make sure when you set your Bios for the 1333 MHz speed that you also manually set the timings for the ram. These should be printed on the side of the ram on the sticker. along with the proper timings you need to make sure the Voltage for the ram is set correctly. This too should be printed on the sticker on the ram. After all of this is confirmed to be correct try to boot. IF it fails recheck everything and move on to the next step.

next IF the motherboard has a way to up the voltage to the memory controller try to up the voltage a little and restart. If it still wont boot then also try to up the NB voltage a little and restart. every time making sure the ram timings and voltage are correct.


If there is a setting in the bios you do not know what it does just try to google it. This will help teach you what each setting is for and help you understand the bios a lot better.
