Safe to run 2x2GB with 2x1GB DDR2?

post #1 of 9
Thread Starter 
Hi!

On my Max2Form, I'm currently running 2x2GB PC2-9600 OCZ Blades. I bought a set of 4x1GB OCZ Reapers (also PC2-9600) off ebay mistekening them for 4x2GB, as a replacement for the Blades.

Now instead of them lying around doing nothing, would it be safe to fill the two free memory banks on my mobo with 2x1GB, or would it cause instabilities?

The system is running at 3,6GHz with 400MHz FSB and memory running at 1066MHz.

yes that should be fine, not recommended, but fine.

It seems the system became very unstable. It was worth a try though smile.gif

Mixed RAM will work, but tends not to overclock as well. Also having more slots populated hurts the overclock, so you're taking a double hit there.

If you back off a bit you can probably get it stable.

The weird thing is: The memory is "underclocked" as it's supposed to be able to run at 1200MHz but is only at 1066. I'm presuming the NB is somehow damaged, as I'm not able to get the memory stable at the stock speed in any way, even with the CPU underclocked. So adding more memory to it, different ones of all things, doesn't really work out.

I need a new board frown.gif

Have you tried increasing the NB voltage?

I'll try that next. Two days ago I did a TIM overhaul on the board too, since the NB was reaching 60°C. Now it's 15°C cooler thanks to Liquid Ultra smile.gif
Leaves more headroom for voltages. I never thought about upping that tongue.gif

Thanks for the reminder!



EDIT: Heh... Increasing the NB voltage from 1,1V to 1,2V made the 1200MHz possible! biggrin.gif
Now let's try adding the other RAM again...
