Trying to Mix ram

John James Walker · Feb 4, 2016

Hi On my pc i have some no named ram in it and it runs at 800MHz But right now i have 2 2gb Corsair Dominator ram that runs at 1600MHz Should i try mix it or will it just fry my motherboard

800MHz is DDR2, and 1600MHz is DDR3. That's two entirely different types of RAM and not compatible, even if you did have a motherboard that allows either DDR2 or DDR3 to be installed.

It won't fry your board or anything, but..

It sounds like the 800MHz RAM is ddr2. The 1600MHz's sound like ddr3.

It's most likely your motherboard only supports one or the other. So it's possible that the 1600's will not physically fit.

I wouldn't recommend mixing the ram. It's unlikely to work. Rather stick with one kind of ram.

Where are you seeing that the ram in your PC is running at 800 MHz? It could actually be 1600MHz ram and you are not seeing the DDR rate correctly.

Best policy: NEVER mix ram. It might work, it might not work.

It is DDR3 Ram but it shows up as 800 MHz

John James Walker :

Oh NOW I see, lol. DDR of course means *double data rate* so whatever your MHz is showing, double it for your true RAM speed. My DDR3 is showing 933MHz even though it's 1866MHz RAM in CPU-Z. Didn't even think about that until you showed me the pic. I assumed you had DDR2 based on your Core 2 Duo hardware referenced.

Yeah That was an old pc i had got a new one now haha so basicly i have 1600 is that what your saying

John James Walker :

Yep! Here's a link to more detail about what's going on. You are good bro as far as the actual speed of it being effective 1600MHz.. If they work nice together and you get no errors, you are lucky. It doesn't happen to everyone when separate RAM makes, even at the same speed, work well together.

Yeah sadly i don't think they will work together because i just tried to install them and just as i was about to stress test it. It blue screened and by the looks of it CPU-Z Says its Crucial Ram

John James Walker :

Yep, it's more common they do NOT work than the other way around. You really need to buy memory in kits (2x or 4x) as those have been tested to work together at the factory before packaging them together.

As crazy as it sounds, even if you buy two separate 1x sticks of the exact same memory, same make/model, they may not play nice due to slight manufacturing tolerance differences on different days. One day the silicon may be better than another day as just one example. There are very complex molecular reasons for that...but it's enough of a reason to screw up electrical signals just enough.

Yeah I'm looking at some 2X8 GB Kits to buy later on in the year because first im saving up for a DFGT Wheel

It is actually Double Data Rate, not density.

Oops, yep, of course it does. I was multi-tasking on another topic discussing something entirely different. I'll edit just so as not to add possibility any miss-information for future thread seekers. Thanks!

John James Walker - what mobo, CPU (is it the 6300 in sig) and the model of the DRAM - if going to try and mix, best to start with only the new sticks, go into BIOS and set the sticks to spec, if all OK, back to BIOS and raise the DRAM voltage + 0.05 and raise your CPU/NB voltage to 1.2 and give that a try

He had his old C2D hardware listed when he posted the original question. He updated it apparently.

Thanx, read it 3 times looking for it

Thought, how am I missing this
