Can I mix these two RAM modules. The only difference I can see is that the timing on one is 8-8-8-24 and on the other is 9-9-9-24. Is this a problem? I already have 8 GB of the 8-8-8-24. I thought I had ordered 24 GB from newegg but they only sent me one and now they're out of stock. I could buy the 8-8-8-24 off of Amazon but it's $54 more expensive...

My processor is a CORE I7 980 3.33G R.

Thank You!

Generally the answer is no, but I'm gonna say yes, it will be fine as long as you match the timings.

But seriously, why in the hell do you need 24GB of ram?

So I can match the timings in the bios or something? I haven't done this in a while.

It's for video editing...:-)

Yes, in the BIOS there should be an option to set timings, if it's not done automatically. Set them both to 9-9-9-24 to be safe. But if you feel like OCing (idk why you wouldn't) you can bump them all to 8-8-8.

The links show dual channel kits , which is kind of weird since you should be looking for triple channel kits to start with

I think you will be alright mixing what you have . BIOS will almost certainly just run them all at the slacker 9-9-9- timings

But you have 4 sticks and will be forcing the board in to dual channel which really negates a big advantage of socket 1366

Send them back and buy a 12 gig triple channel kit [ or two]

Great! If it's that easy I wonder why they charge 50% more for the 8-8-8-24 RAM. I mean I have enough invested in this computer that I don't mind spending a little extra to avoid headaches down the road but if you think the 9-9-9-24 RAM will work I'll just go ahead and order it now.

It's frustrating because I know I ordered 24 GB from Newegg but when I submitted the order they said my order needed to be changed but they didn't tell me what was changed and for some reason I couldn't find the discrepancy at the time. It's annoying because I live in Germany and the shipping for the build was $150 and I had to wait a couple weeks to get it.

I basically just used the DIY8 hotrod build listed at the end of the below link on When I did a search on Newegg for the RAM they suggested I came up with the RAM that I bought. But you're saying it's not even the right stuff for me? I'll follow your advice and return it, but can you suggest a specific RAM module for me?

Well, you can make due. If you get a total of 3 dual channel kits, you will have your 24GB of ram, and it SHOULD run in triple channel.

In the end I'll have 6 sticks (4gb x 6). Does that change things?

Yes it does , but you would be far better off with triple channel kits

I would find a site local to you and buy RAM there , designed for the mb

This is the Motherboard I have:

Any specific recs for triple channel RAM?

I'm not going to buy RAM over here because I'll just get killed on the exchange rate. I don't know why the newegg shipping was so much (since it shipped to an APO address) but I'll use Amazon for this RAM purchase which should be free since I'm a Prime member.

Would this work for instance?

That is the kind of kit you should be looking for .

The cl9 timing is not that special . I believe you would see performance gains in encoding and editing by using lower timings , but they will cost more so its really a matter of budget .
You can also check the supported memory on the Asus page

But in practice its very rare for memory [ of the right spec] not to work , even when its not on that list

Mixing RAM is never recommended and often will not function together. It's a crap shoot.

At the low current prices of RAM you would be smarter to buy a Tested, MATCHED RAM kit instead of mixing and hoping that two different RAM DIMMs will work together as they often won't even with the same timings.

The gSkill RAM is really old stock , the other one is outrageously expensive .

Beentheres advice is !00%

OK well I appreciate the advice on what not to get, but can someone make a specific recommendation on what I should get?

The best is the Mushkin blackline, simply because of price. HOWEVER, they are all quite expensive, IDK why.

These G.Skill Snipers would do the job:

Or some Vengeance:

Or some HyperX:

Basically, just get some cheaper stuff! I know it's CL9, but it won't make much difference.

Thanks for the advice Striker. I bought the Vengeance RAM that you listed. I did a little research and found a Tom's article that suggested that expensive RAM really isn't worth it. I wouldn't have minded spending a little extra if it would have made a real difference but it's always nice to save money. Thanks again for your help!
