2133 vs 1600. Is it significant? - Page 2

post #11 of 21
And cas 9 2133 is faster than cas 7 1600.I have tested it myself with maxxmem those are the results.

Not to mention I have seen a lot of results from benchmarking here that back up my claim.

Here is one of them

So virtually after 1600 Cas 7, it's not applicable to anything but benchmarking?
post #13 of 21
Pretty much. It's the best bang for buck at that point.

No, hell no. If all you're doing is gaming, photo/video/general web browsing, etc. the difference between the two will be indistinguishable. However, if you are a hardcore benchmarker and benchmark continuously, then perhaps. In short: you won't see any real-world difference.

Tom's Hardware showed a slight real world benefit of 1866mhz over 1600mhz on a socket 1155 Sandybridge chip, but even then it was almost neglible.

The point that they were getting at is that with socket 1156 and 1366, we were saturating the imc with bandwidth at 1600mhz. Thus the tighter timings gave a more tangible benefit than simply oversaturating the memory bandwidth which was already saturated at 1600mhz.

With socket 1155, the controller seemed to be fully saturated at 1866mhz, which means that the little bit of extra speed did give a benefit, but even then it's not that much.


In conclusion, I would go with the 1600mhz cas9 set for $100 on newegg. Spending double the money for 2133mhz ram is a waste in my opinion as paying an extra $100 for a <10% performance boost is wasteful. The ripjaws-X should be able to be pushed to 1866mhz with a little bit of extra voltage or maybe the timings could be tightened to 1600mhz 7-7-7-21-1T (it's a maybe but it's alot cheaper and it's the point of overclocking).


The arguement going on above is in my opinion is simply the wrong arguement. It's not timings over speed. It's more of saturating the speed and then tightening the timings. Even then, this arguement is pointless as we won't see a difference on socket 1155 above 1866mhz and the difference in timings is almost solely found in benchmarks rather than in real world usage.

tl;dr save money and get a 1600mhz kit. overclock it.

8GB 2133 for 199 w/ Ram Fan.

That being said, is the 2133 worth 85 more?

2 sets of 4gbxh and oc them to 8-10-7-27 2133

I actually research my answers before trying to tell someone they're wrong.

Cas7 at 1366 is faster than cas8 at 1600.

I knew I had seen that chart before, but could never find it. Thanks for reposting it!! cool.gif

Get these and save your money. They're not very good OCers as I can only get 1648 out of them at the stock 6-8-6-20 timings. And they won't go any lower then that either. (3X2GB i7 sticks, your 2X2GB are 6-8-6-24 stock) But with CAS6 @1600 they're very fast. Like the old 6-8-6 Mushkins. Most i7s can't go above 1850 any way so stick with the tighter timings. I tried 2 different sets of 2000s, Super Talent and Corsair and either one wouldn't go any higher then 1850. But they did do 7-7-7-20 @1750.

Actually it's the opposite. Intel does better with higher frequency generally, and AMD does better with tighter timings generally.

Anyway, there is going to be no real world difference between 2133 and 1600; and RAM fans are pointless. If you are an enthusiast and want those extra few points in SuperPi then go for it. If you're the average user then no, I would not recommend it at all. Running faster memory means you have to give more voltage to the memory controller, and in the case of Sandy Bridge that's VCCIO voltage. More voltage to the memory controller equates the CPU running a little hotter.

This is a old post. They don't make/sell Elpida chips any more. I and everyone else here wishes they did but they were to unstable and didn't last very long. The old Mushkins I'm talking about in my post were these chips. Along with Elpida Hypers which were even faster and more unstable then the Elpidas. They stopped making them 8-10 months ago. About the time of that post.
