The difference is bigger than you think thumb.gif



Bogus. I shun you for this. doh.gif This review is hugely irrelevant to here. This was made in the Core 2 Duo era. Basically what I'm saying is: 1. at that time pretty much all DDR3 ran generic timings which were at times a lot worse than the equivalent DDR2 generic timings, 2. Memory controllers had not matured to fully utilise DDR3 yet 3. They don't even test DDR3-2000.
Interesting...

So on the one hand, we see people who find absolutely no difference with different ramspeeds. On the other hand, we see people who find a 33% increase in FPS. What's the difference? When or why does ramspeed become a bottleneck?

Not if it can be used in the future... if there is no real-world difference between 1066mhz and 1600mhz, then it wouldn't be a benefit. And if there's a miniscule difference, I'd rather have more ram for the future. I'd say if there's a 10% or greater difference, it'd be worth it. Beyond that, I'd just as soon get more ram instead of faster ram.

Besides, 3GB is silly small. tongue.gif I recently upgraded my desktop from 4GB to 12GB, just because I had the extra ram, and I definitely notice a difference in general system "snappiness".
post #22 of 30
I recently went from 4GB of DDR3 1333 to 4GB of DDR3 1600 and I can say for a fact that my programs load a little faster and the system feels more responsive/snappier.
Adding a Quad Core soon after made things run even faster...but that is to be expected.
I have not seen any change in FPS from getting faster RAM but I have seen my games, programs and OS loading a smidge faster.

Personally I recommend DDR3 1600 if possible just because it balances speed, timings, ease of overclocking and price. But in my experience RAM speed and timings do not have much to do with game performance. It can, but in general unless you make a massive upgrade like DDR3 1066 to 1600+ there really isn't an increase.

I have seen (and experienced) heavy overclocking being easier on faster RAM. the difference between heavily overclocking a computer with 1333 and 1600 seems to be pretty noticeable when the total time spent overclocking/stabilizing is looked at. I spend much less time getting Stable and getting to the OC I need to be at with 1600 and above. For some reason faster RAM seems to be a little easier to overclock with, but it is by no means a barrier. Ive reached 4Ghz on computers with 1066 and 1333 several times. It just seems to take more fine tuning.

I don't think recommending anything over 1600 is valid. And when I see people doing it I want to call them on it. But aside from my personal experience I dont have any data that I can point to.

Duckie does have a valid point though. If you have less RAM, being able to access and utilize it more quickly is a bonus, even if its not really noticeable on the user end of the screen.

Thhis is actually a very good question the OP has brought up

How come nobody that has commented that has say 2000mhz RAM running tube own rig to 1600 or less and run somme bechies?

I would have done it a while ago but as I stated erlier my RAM is in for RMA

Mikrouwel

You mean underclocking 2000mhz to 1600 and running some benchies and comparing?

2000 had a little higher read/write/copy speeds. If I loosened my 1600 timings the difference in speed would be much greater, but I tightened the timings at 1600 and brought the 2 close to the same speed, but 2000 had an edge.

The Comparison was between 2000 8-7-8-20-1T and 1600 6-6-5-15-1T. 2000, again, a little faster, but the tighter timings made quite the difference.

Really depends on what timings you have though.

EDIT:

These were my results, take them for a grain of salt if you will.

With the information presented here thus far, I wish people would stop recommending higher speed/lower timing ram to new builders. IMO, it is much more valuable to buy MORE ram than to buy faster ram. I'd 10x rather have 6GB of 1066mhz DDR3 than 4GB of 1600mhz DDR3, but that's probably not the recommendation that would be given on these forums if I asked the question... sad, really. People need to understand the benefits (or lack thereof) of higher speed ram vs having more ram.

When i first joined OCN & asked about memory purchases, enough people recommended the corsair dominator 1600Mhz cl8 kit that I went & got one.
After that I started benchmarking a bit & liked it, then discovered just how badly the memory kit sucked for overclocking.
I kinda wished that more people had recommended something better, would have saved me some monies since I had to go get another kit that could handle the overclocks I wanted to throw at it. Getting MORE of it just would have been a bigger mistake.

It is interesting. I think there isn't much difference between any of the high end ddr3 ram, I think HDD and CPU are proving to be more important components, my SSD upgrade was the most noticeable. Gaming is purely GPU and CPU based, so I would be surprised if higher clocked/better timings would increase FPS. Would be nice to see some real world tests though.

i saw some testing between 1066 and 1600 and 2k rams on x58. and the difference in gaimg was noticable between the 1066 and 2k ram. it was like avg 10-15 fps difference in gaming. in some rendering, coding etc it was even bigger gain from faster rams (but this is obvious lol). however i dont know what site it was with this test :S but the more power you got with your cpu, it will be always better to go with better ram. also keep in mind that ram is only a small part of pc itself. the 2k rams will not magicaly unleash the +100% of computation power compared to the 1066 rams xd

Obviously you're gonna see differences in benchmarks. I think the OP is referring to real world applications, though.

If DDR3 2000 Cas 6 RAM is gonna decrease your video encoding times by 20% over DDR3 1333 Cas 9, then hell yea it'd be worth it. But if it's just 2-3%, that's negligible.

A real word app would be After Effects. There you make a RAM-preview so everything that is rendered is pushed in the RAM. The more RAM you got the longer you can make a RAM-preview. The faster the RAM the faster the rendered frames can be pushed into it.
But you need a funky a** CPU that renders fast enough to benefit from the faster RAM speed. MaxMem says I can write into my RAM /* DDR3-1333@1452MHz */ with 8730MB/s.
I don`t think my CPU is able to render 8,7GB/s to fully use the "high" RAM-speed!
