2133MHz, c9 vs c11?

post #1 of 7
Thread Starter 
Just curious how much of a practical difference there is between these timings.

I'm considering upgrading to a 4x4GB kit since I've been regularly hitting 6GB+ usage in PS, and the two sets I'm looking at are 2133MHz w/ 11-11-11-30 and 9-11-10-28 respectively. The later being $25 more expensive.

The price difference isn't a lot, but it's my understanding that 1155 cares more about raw MHz than timings, so if the two perform about the same I may as well save the cash, right? Any thoughts?

You won't notice anything irl, only benchmarks. Also, keep in mind that some games actually runs greater with 1866 than 2133. smile.gif (this is my own experience, but I don't have an article to proof it, I remember reading abot it somewhere) smile.gif

more/additional memory will give you extra bandwidth and few FPS gaming in some of the games , i would take C9 over C11 any-day especially for $25

I was going to originally until I read that xbit article. Looking over their charts, timings don't seem to have much effect on performance. They even say:

What benefit do you see from tighter timings (besides higher bench scores)?

If you're planning to use 4x4Gb with the 2600K in your sig, note that in many cases CPU's IMC (integrated memory controller) won't be able to hold 16Gb at DDR3-2133 so you'll be limited to DDR3-1866 anyway.
Besides, memory has very little affect on the actual performance so unless your rig is worth thousands, spending extra $25 on memory might not be worth the 1% gain it yields.
That is, I suggest you go for the cheaper option.

This pretty much sums it up as for .."what Ivy should roll" ..for SB you are limited to 2133 so i would just get 1866/2133 fairly tight and call it a day

The Ivy Bridge memory controller is largely the same as the Sandy Bridge one and delivers similar performance at the same settings. So, the influence of system memory settings on practical tasks is rather low. However, the new CPUs have brought about certain changes, the most important of which is the opportunity to choose a very high clock rate for DDR3 SDRAM. Such clock rates were not possible even with overclocker-targeted systems of the previous generation. As a result, the range of DDR3 SDRAM offered for LGA1155 systems has been extended, increasing the gap between configurations with slow and fast memory. By changing the memory clock rate alone, you can see a performance boost of 5-10% while applications that need large amounts of data (such as games) may get up to 20-30% faster! So, choosing the right kind of memory for you LGA1155 platform is important. We must note, however, that such benefits can only be achieved after a twofold increase in clock rate whereas a single 266MHz step up leads to a mere 2-3% increase in speed.

So, the rational approach to choosing system memory is in looking for the optimal frequency/price ratio. Modules up to DDR3-2133 SDRAM may be recommended for Ivy Bridge platforms, but not faster ones. Up to that frequency, the price remains reasonable while the performance in everyday applications grows up. Faster memory modules are considerably more expensive without providing tangible performance benefits, so they can only be recommended for enthusiasts who want maximum speed no matter what.

You shouldn’t bother about memory with low latencies, by the way. There are fewer such products on the market nowadays because low timings do not offer much in terms of performance on the modern LGA1155 platform.

Spend the extra $25 and get the 2133MHz kit. If it don't run the 2133MHz spec, downclock to 1866MHz with tighter timings. Tight high frequency ram helps in 3dmark11 benchies as FTW 420 pointed out a while back. I would assume it would help also in FPS in your favourite games too.

Another point is to buy the best sticks as you can so that you can carry the ram sticks to your next build when 2133MHz is alot more standard. And maybe later you'll want to overclock/bench your ram one day, you never know!smile.gif

So it doesn't hurt to have some pretty good timing sticks.

I myself notice a snappier system with faster ram.
