Hey guys! I'm going to be adding RAM to my PC in the next few weeks, but I have couple questions that Google isn't helping me with. Right now I have 2x4GB Corsair Vengeance 1600Mhz. DDR3 SDRAM, 1.5 volts, Cas Latency of 9, and a timing of 9-9-9-24. I'm hoping to buy this 16GB dual-channel kit. My original plan was to swap out the 8GB dual-channel kit I currently have for the 16GB kit, but since my motherboard (Gigabyte GA-Z77-D3H Rev. 1.0) supports up to 32GB, has four RAM slots, and I'm running Windows 8, can I just add the 16 GB kit to my existing 8 GB kit, for 24 gigs total? Is there a downside to doing this?

Thanks in advance!

Obligatory bundle game giveaway.

You should just download more RAM but I don't actually know anything.

There would be no downside, just make sure that you place them in the right order. For example, 4GB - 8GB - 4GB - 8GB

Yes, but the ram slots needs to be compatible with each of the ram.

the thing is, your never going to need 24gb RAM for anything.....the most you really need is 8gb, but whatever, do what you want.

ive got a 4gb page file to go with my 4gb of system ram and i dont do anything like photo or video editing so thats patently untrue, when games starting to ask for minimum 6gb 8gb isnt alot

I once had a computer salesman allege that I'd never need a hard drive larger than 40 gigs.

Yeah.

I remember buying a 340Mb HDD back in 1992 and I thought they wouldn't get any bigger :p

It always depends on what the person does with the computer.

I'm currently hovering around 10 GB of RAM used, and I'm not even in a game right now. I wouldn't go under 16 GB, ever.

For someone doing some large scale 3D modeling or video editing, more RAM can only help. Don't try to apply your personal use to everyone's situation. For regular Windows usage and gaming, 8 GB is probably sufficient. To me it's a baseline. (That's what I put in my girlfriend's computer, as well as my kids'.)

I have 8Gb and I really need to upgrade to 16Gb (max of my motherboard) or buy a new motherboard with 16Gb/32Gb of RAM immediately.

Why I need it myself? I'm programming and have started on 3D rendering/animation. Though 8Gb should run it, I prefer to have both my game engine open (Unity3D), the world editor I use for it (Axis Game Factory) and the 3D program (Blender).

...and yeah, I want 3 monitors as well :p

I always use the RAM that's recommended by the manufacturer. The list of compatible RAM for that motherboard is found here: Z77-D3H QVL

If the RAM you want isn't on the list you can usually cross-reference using a search engine.

The RAM you install should match whatever is already in there for best performance.

Not all your ram needs to be matched--just those installed in the same channel. For more information, see here, about 1/4 down the page (search for the first and second occurences of the word identical)

Very true. I'm using 2x2Gb Corssair and 2x2Gb ICIDU in my system. Somehow the two doesn't really like one an other when one of them is placed first (don't remember which). All banks are 100% fault free, run fine with only their own brand in the PC, and as they're setup now. But the moment I change the banks my PC gets lots of trouble and BSODs in Windows.

I just bought myself another 2 GB, it should get here tomorrow or so. I matched it with the other 2GB I have in my laptop, so it should increase efficiency as well.

Just checking: there is a reason you need so much ram, right? You do a lot of video editing while running a vm server cluster in the background?

Currently, you only need 8gb of ram for games. Games do not take more than that right now. Only need more if you are doing multible things at once.

6GB at max currently for games

Using 4Gb of RAM with FX 6350 and GTX 650Ti and haven't got any problem until now :)

I wouldn't mix and match ram sizes. Just replace the 8 gig kit you have for a 16 or buy 2 16's or a 32 of quad channel memory. Alternatively for the cheapest option buy another matching 8 gigabyte kit for 16 total. if you're mixing ram vendors and sizes you can run into a lot of memory issues like xmp profiles being disabled as well as one kit running in dual and another in single channel. Sometimes it may not work at all. Play it safe and buy matching vendors/sizes.

Thanks for your advice. I think I'll just buy another 8 GB dual channel kit instead.

Matching timing is more important than matching size. Theoretically, there shouldn't be any issue running 8GB/4GB modules alongside each others. Matching memory from different vendors however, it's always a gamble.

It's always safer to go with a matching set bought together. At least they're certified to work well together and you're not left diagnosing weird problems and memory corruption.

I can back this opinion up as well. Have had a bad experience with two different vendors on same laptop.

What if you get different sizes but same vendor & Mhz?

Different timings, sizes, vendors can all introduce problems. It's hit or miss. With the current price of ram being on the higher side I personally wouldn't risk mixing and matching. It's not that's its impossible to have completely different ram. It can just complicate things. If you already have the extra ram then go ahead and try but if you're going to buy it just be wary that problems can happen.

I've had a setup running-> 4 GB x2, Slot 1 has like PC12800 and Slot 2 had like PC10600.

It was crashing constantly. Finally was able to get a hold on identical memory to Slot 1, replaced the 2nd one and now that machine is running flawlessly.

Note to self, never ever mix RAM sticks ever again.

My advice is add new 16GB and see what happens. Just check in MB manual which slots work as pair so you would not mix different sticks.

Just make sure you're actually running a 64bit version of your Windows 8, because 32bit OS can't access RAM > 4GB (unless they've done some quirky workaround in Win8 that I'm not aware of).

"This is not an architectural limit; it is a limit imposed by Microsoft as a workaround for device driver compatibility issues that were discovered during testing."

As it says, it's disabled only because some 32bit drivers won't work with over 4GB of memory space. (Some hardware requires memory space too, which reduces the limit of RAM). You can actually use patch to disable limit.

He said he already had 8GB of RAM. I think it's safe to assume he already had a 64-bit OS.

You need 8gb of ram for gaming or 16gb for professional edition

Put more ram is one of the worst waste of money you can do rigth now

RAM is actually pretty solid in terms of upgrade. There are better upgrades (SSD for everything running off of the SSD, GPU for gaming, CPU for overall processing) but for the most part RAM is a cheap way to upgrade your overall performance for not that much more.

Memory with heatspreaders are the worst purchase. Do you want it to have a roof or to fit?

10 years ago
Permalink

Comment has been collapsed.

Heat spreaders can usually be removed by the consumer. The backlash against them often causes RAM with heat spreaders to be cheaper than comparable non-heatsinked RAM, so aftermarket removal is a great idea.

If the heat spreaders can't be removed by screws, slides, or otherwise disconnected, you can snip it off if you're fine with never being able to reattach it.

My case is huge, and already houses RAM with heatspreaders, so this is a non-issue for me.
