Overclocking Asrock G41C-GS

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   RAM
Compatibility with 4GB sticks

CPU:
Q9550

MB:
G41C-GS

Cooler:
Zalman Performa 

Graphic:
GT 610

I
purchased this MB from Newegg several months ago, and have had no issues
running it with DDR2-400MHz. The FSB has been running stock at 1333MHz since
installed, with a BCLK 333MHz.  I
purchased this board to replace an old Asus P5GZ. So I needed the ability to
drop in existing components and have a running computer. Namely CPU and DDR2,
now I am trying to get the 1333MHz(OC) ram running, because I am trying to max
out the ram to increase performance for kids games (Minecraft and the
like).  

I am
running the beta Bios 1.40C that I flashed from the Asrock site, allegedly to
increase DRAM compatibility. I have moved the jumper to the 1333MHz side, and
it will boot with DDR2 fine, at stock speed and OC(BCLK 340 FSB 1360). However
when I install any DDR3 stick I get the black screen issue with fans etc. And
before anybody starts posting about QVL, Asrock does not have any 4GB
DDR3-1333MHz modules listed on the QVL for this board.  

Ram
stick I have tried:

Pacific
Sun  x51642133P

Patriot   PSD38G1333KH

Corsair
XMS3  CMX8GX3M2A1333C9

I have
also tried raising the PCI clock from 100 MHz up 108 and still nothing has
worked. Not sure what the upper level of safety for the PCI clock is, and I
would prefer not to have to OC the PCI clock if possible.

So what
is the process for getting OC ram to run in general, I assume it is something
like:

1: OC
computer BCLK or Multiplier (achieve a stable point and test)

2: shut
down and install OC ram 

3: boot
into BIOS and adjust ram clock setting if necessary

4: load
OS and test again

Am I at
all close on this, I know that people say you should flash CMOS, but then it
removes all BIOS setting and then you have to start over again.

Please
help

thanks

	Welcome to the forums. I need to clarify here, are you trying to install DDR3 and DDR2 RAM on the same board? Your post makes it seem that way, if so, that is why you are getting a black screen. You cannot install DDR3 and DDR2 on the same system. If you are not using both DDR2 and DDR3 then it may be that your RAM modules are not supported. Do the DDR3 modules boot if you do not set the jumper to 1333?

	No, Using DDR2 to boot to BIOS and adjust settings. Then remove DDR2, and install DDR3. With DDR3 installed it will not boot with jumper in either setting. The CPU fan comes on and hard drive spins up but then it will not boot. And I get the black screen issue. Sometimes it resets itself like it is registering the ram but it never finishes the POST/boot. The XMS3 ram is supposedly compatible with G41 chipset. But maybe not I really don't know at this point. Thanks

	Ok great, I had to be sure you were not trying to run both types at the same time. Have you tried simply installing the DDR3 RAM then clearing CMOS? You say you are inputting manual settings using the DDR2 then installing the DDR3, this could be part of what is causing the problem. Manually inputting the settings prior to installing the RAM is not advisable, it can make the system try to initialize the DDR2 slots rather than the DDR3 ones. It is usually best to clear CMOS (I prefer the battery removal method) when ever you install new RAM as it forces the board to redetect the RAMs settings and voltage. DDR2 and DDR3 use different voltage so if the board is retaining voltage settings it would explain why the DDR3 won't post. Good luck.

	Hello, Ok, I tried flashing the CMOS with the DDR3 , as you suggested and still get the black screen issue. I tried it with the jumper in both positions., and nothing worked. tried both sticks in both slots. Is it possible for the DDR3 side of the memory controller to be bad but the DDR2 side to work? Question, How does the board recognizes the OC ram, if it requires the CPU to be overclocked to run ram at that speed. When you flash the CMOS all setting go back to stock speed , how can it load into the bios if it cannot operate the ram? thanks for all your help..

	I did a little research and it seems that your board is very picky about what DDR3 RAM it supports. There is a thread on the Tweaktown sponsored ASRock forum about this same issue. You should find all the info you need there. Hopefully this helps resolve your problem.

	I can't really hope to see 1.5 bios with more memory compatibility ... Kingston HyperX 2x4Gb 1333 Mhz CL9 Nothing works, even after switching FSB1 plastic thing set. I have currently Q8200@1329.73 Rated FSB, as default value. Maybe it's an option that i missed ? Or it's really compatibility issue ?
