1333 or 1600 DDR3?...Big difference?...or Not?

Hey,

As the title says guy's/girls....is there much of a big difference between the 2 different speeds? If so, what applications would I benefit in?...Im mostly a Gamer

Im not really looking at overclocking the RAM, mainly the CPU....I have always been a big fan of Corsair and it has never failed me yet. But I've also seen how OCZ is going really well and their memory seems cheaper than Corsair in some places I have looked....Is there any difference between the two that I should look for...also any particular models that are a good buy atm? Im after 6GB so you know.

Im looking at getting parts starting early next month for my i7 build, I got everything else apart from the CPU, Motherboard and RAM.

 

As I have stated in every thread with the same question.

 

i recken go with the 1333 mhz and save a bit of cash. As their is bugger all difference

 

The biggest difference you'll see is on a top end OC. If you are not going to be OCing heavily, then 1333 is good for most people.

 

What overclock are you hoping to achieve?

I just sold a set of Corsair XMS 1333's, they happily ran at 15XX Mhz at stock voltage. I wouldnt suprise me if they used the same ic's as 1600mhz ram just binned differently and lower voltage.

1333 "may" hold you back on an overclock if you cant get a divider for the memory to be close to stock speeds, but in most cases you will have something close to stock speed (or below if you can stomach that! I cant lol)

As for performance, aside from benchmarking such as super pi, you may see 3 or 4 fps difference when running 640x480 res (Yes I do mean 640x480 )and using a GTX295. The i7 has ample bandwidth that really the only factor is 3 or 6Gb ram and 1333 vs 1600 in terms of what overclock you want to achieve.

Obviously if you are a die hard bencher then you want every last fps so you drop $500 on ram.

 

I want to get my i7 920 to at least 4ghz, but I heard the new d0 stepping is going to be released soon which can overclock a shitload better.

 

yeah D0 should OC better, basically the like the B3->G0 Quad revision, cooler, less power hungry = more OC'able. But honestly going from 3.6->3.8->4.0->4.2 etc will currently give you nothing except a larger e-penis, I am yet to find a game that needs my i7 @ 3.8 .. however the recessive overclocker gene always seems to kick in.

1600 will always buy you a little breathing room, but with dividers you should be able to find some mem setting that is close to default.

 

i was running 12GB DDR3-1600 and getting latency of 52ns in everest and placing first in every other RAM test.
But it is unstable with hard lockups instantly.

I don't have the fan on them yet, so it might be that.
They are running at 1333 now, still get first place in everest ram scores, but latency is now 59ns.

 

12Gb as in 6X2GB? If so the i7/X58 apparently cant run 6 sticks at higher than 1333Mhz.

The wierd thing about pricing for i7 memory is the 1600Mhz is often cheaper than 1333Mhz. Probaly supply and demand as most people advise to go 1333Mhz and the poor old 1600's are left on the shelf.

ANd you pay a hefty premium for 1333 with Cas 8 timing. The corsairs with Cas 8 were like $350(3X2) but you can do what i did and buy something like GSkill 1600Mhz cas9 memory and run it easily at Cas 8 at 1333Mhz. And its half price at around $185. Also it runs at 1.5v. vs 1.65 of the corsairs.

I like Corsair ram but the price of the performance stuff is ridiculous, and they are usually the highest priced ram aroound these days. There are other much cheaper options, that perform just as good.

 

I was just reading through one of the articles posted on the main page linky link link and at then end:

 

im sure it CAN run 6 ram sticks at 1600, it probably needs a voltage boost in specific areas.
Apparently, QPI voltage needs a small kick.

Still reading into it.

 

depending on what brand you get DDR3 1600 could cost you an extra 50 bucks for a 6gb kit so go with the 1333MHz, any way to OC that ram to 1600MHz you will probz go over 1.65V and possibly fry your i7.

can anyone tell me if that is bs? cause im finding it hard to believe 6GB of 1333 ram that runs @ 1.5v would be at that price point
EDIT:
it say 1.65v on arc:
http://arc.com.au/pub.php?gid=23589&pid=35158&p=product

but corsair themselves:
http://www.corsair.com/_datasheets/TR3X6G1333C9.pdf
says Vdimm:1.5v

was wondering if anyone has had experience with these

 

get 1600Mhz if you want to run your ram between 1333MHz and 1600MHz but video about OCin ram said that to get the ram over 1600MHz you need to increase the voltage to about 1.67v (on the i7 920), you might be able to get over 1600MHz with the i7 965, But still unless you are do alot of OCin go for the 1333MHz save your money

 

It is a big oc from 1333 to 160omhz with out adding vdimm volts but there would be 1333mhz ram that would oc the 1600mhz with out adding voltage it a matter of seeing what others are clocking and with what.
Need more answers

 

Im not overclocking, just default settings will crash after 20 mins with 12GB of 1600 RAM.

Pic on LEFT is 1600 XMP defaults - Pic on RIGHT is 1333 XMP Defaults

 

You were correct when you noted earlier in the thread that you will likely need more QPI voltage. Have you tried this yet? My guess is that you will need between 1.25v and 1.4v on the QPI to run 12GB at this frequency.

Are you all saying that Dominator GT PC16000 RAM isn't worth it?

Blasphemy.

 

Just bought a set of those corsair 1333 6gb 1.5v kits from vtech, soon to find out if its true. Hopefully when they arrive today I'll be able to report what the packaging and sticks themselves say, but it will have to wait until friday night to put the rig together as to if they're really 1.5v as reported.

NINJA EDIT: Speak of the devil, it just arrived. And the package and sticks are definite, it's ddr3 1333 6gb triple kit with 1.5v vdimm and only $150.

Sweet deal.
