RAM Latency question

[TigersGhost]

Hello.

I'm about to buy a new set of RAM and I am wondering one thing. 

So I'm going for a RAM that has as low latency as it can be so i'm gonna have CAS 9. I know that latency between CAS 9 and 10 is "benchmarkable".

But here is the question, while browsing for RAM I noticed that latency is shown as "9-10-9-27". So what is the difference between 9-10-9-2 and 9-9-9-24? Is it noticeable at all?

I want to go for the RAM set that has 1866MHz but that's the one with 9-10-9-2.

Which one should I get?

Also while I'm at it, Second question, What is the difference between PC3-12800 and PC3-15000?

the only even barely noticable number is the first one (CAS) and even that one, in most cases isnt more than 1-2fps important unless you are doing any ram intensive work

High Mhz and low latency is good. If your get higher frequencies, latency will go up. the only latency that really matters is the first, the cas latency. some programms prefer higher frequencies, some prefer lower latency. for example bf4 prefers higher frequencies.

Timings don't mean anything in gaming, only in statistical benchmarking is where you will see the gains. Tho to the human eye you wont really notice any improvement at all. Go for the better quality, lower voltage, and cheaper brand. The only real important number if any is the first (CL). Which is the delay time between cycles, obviously the lower the CAS the more responsive the memory. You can get 1866 MHz chips with 8-9-9-24 timings for a few dollars more than other 1866 sticks. Tho really it doesn't matter the difference between that and 9-9-9-24 is negligible. It might be even better to save the extra $3.

 

Also while I'm at it, Second question, What is the difference between PC3-12800 and PC3-15000?

PC3 means that it is DDR3. The number after the dash represents the transfer rate in MB/s. For example PC3-12800 has a transfer rate of 12800 MB/s. Or in other words is capable of 12.8 GB/s bandwidth.

Ah thanks for the help, so what makes a good RAM? I'm looking at this one http://www.corsair.com/us/memory-by-product-family/vengeance-pro-series-memory/vengeance-pro-series-16gb-2-x-8gb-ddr3-dram-1866mhz-c9-memory-kit-cmy16gx3m2a1866c9r.html

And stupidly am ready to sacrifice looks for performance since I got a huge window on my case. Are RAM's like Gskill and such worse than Corsair? 

But I think i'm gonna take the one I linked to because of its looks and it being a nice reputable brand.

G.Skill and other popular companies use Micron D9's. Which are the highest quality DDR3 chips available on the market as far as I know. So if you pick a name brand you shouldn't worry about reliability. Something like these (red | blue) are what most people will recommend you (both on sale too). You don't have to go crazy with spending money into ram, unless you like paying for ascetics.

G.Skill is everything BUT worse than Corsair.

Corsair may be a bigger name, have a large variety of products, but that doesn't make them the end all be all.

 

G.Skill provides a lifetime warranty on their memory products...which is FANTASTIC.

Their RAM heatsinks are not ridiculously large (I'm looking at your Corsair), so you don't have to choose between CPU cooler or RAM.

Plus, G.Skill DOMINATES in memory overclocking. Just look at the world records.

WOW

Now I really want to get F3-1866C8D-16GTX. G.Skill seems much better than Corsair, I don't see corsair making CAS 7 1600MHz  .

So now is the problem of getting it... I live in Sweden and I cant find it anywhere 

Also, if I manage to find it somehow, can you take the "sticker" off it so it looks better to me?

I imagine you can peel the sticker off just fine. Tho you have a lot to consider if you do. It might void the items warranty, and it will be hard identifying exactly what the stick is. The sticker tells everything about that particular stick of ram. Personally I would leave them on as I am certain it voids your warranty (can't identify item if it has no serial). Just leave them on, they aren't that noticeable once installed into a machine.

I use G Skill in everything but one computer and that has Corsair ram that proved problematic at one point.

 

I have had great success OCing most of the G skill ram kits I've had and with their RMA, exchange, and customer service. It's about as painless as it can be.

 

There are services that you can have something sent in the states and they will forward it onto you. Ram is also small so even if you did pay for shipping it shouldn't be that bad. Even a friend should be able to make it happen without much effort.

haha, I thought of saying "You won't convince to get something else than Corsair" in the first post, now I only want G.Skill.

Thanks for all your help  :lol:
