So how does lowering the voltage affect memory performance of memory rated at 1.65V?

The Patriot memory I bought runs at 1.5V at 1333 speeds with the advertised 9-9-9-24 timings...Should I just adjust it down to 1.6V?

1.6v is higher than 1.5v

But you said your memory runs at 1.5v 😕

It's better to run at a lower voltage if your memory can run stable there.


Who's on 1st, What's on 2nd and I don't know is on 3rd

It runs at both voltages which is why I asked which voltage should I run at?

Will the memory perform better at 1.65V at the risk of decreasing the lifespan of the chip? If so, is this performance gain even worth running at 1.65V over 1.5V?

Or would running at 1.6V give me some increased performance over 1.5V and minimize any possible damage from running at 1.65V?
 
The "performance gain" is binary: either the 1.5V is sufficient for the memory to function, or not. The only reason that anyone increases the voltage for is to make the memory stable.

In other words: no increased performance. Stay at 1.5V.
 
Another question for those in the know ..

What applications actually benefit from 1600 vs 1333 ?

Wasn't there a detailed article by Anand that showed very little difference most of the time ?

also of note, G.Skill is selling kits of "Ripjaws X Memory" which they say is specially tuned for SB, but im assuming this is just marketing. does anyone know what the difference is between these modules and the standard ripjaws? i already have 2 kits of the Ripjaws memory in different systems and if there is no difference i may consider looking at these specific kits again for cross testing purposes in the future

It's hard finding any info about whether or not the ICs in the Ripjaws X series are different (better) than the regular Ripjaws. G.Skill is pretty tight lipped on the whole thing, but I sincerely doubt they perform any better since they're still less expensive than their 40nm ECO kits and those ones don't perform vastly better than the regular Ripjaws. I would have really liked to try the kit, however the height of the stupid fins makes it impossible to fit under my cooler.

how is this ram? is this any good? its rated at 1.65 v

Why not go for these ones? Same brand, frequency, CAS but 1.5v. The tall heat spreader might be a problem if you have a large cooler though.

Since this thread is already on the topic, what kind of memory requirements does sandy actually have? i havent seen any mention of it specifically requiring 1600MHz vs 1333 the way Lynnfield did, and the best 2x4GB kits right now that im looking at are 1333 C7-7-7-21 1.5v (both G.Skill Ripjaws). now right now most of the kits i'd consider paying extra for are out of stock, or out of my price range currently anyway, and im trying to do this upgrade as cheaply as possible since im a little strapped for cash at the moment but my main system's board is beginning to show signs of early degradation from the extreme stress i generally put it under, so i need to decide what memory im going to get now, and jump on it within a few weeks when i have the cash if the price is right.

i am also wondering this. why 1600 vs 1333 besides it being faster of course!! how about running the memory at 1 to 1 ratio? will that be possible with sandy bridge? sorry for noobish questions!!! 😀
 
So how difficult is it to adjust the settings properly for 1600mhz if I have zero experience with bios tinkering and OCing or anything of that nature? Also do I want 2x2GB or 2x4GB if my typical use will be gaming + ventrilo + 5-10 tabs open in firefox or chrome at once?

That's odd that whole tuned for SB wasn't there when I considered that memory a week ago. I ended up going with GSkill Ripjaws 1600 @ CAS 7 for $159. So far this system is stable and smooth @ 4.4ghz
 
i have not seen a 4gbx2 DDR3 1600 kit with C7-7-7 timing, they simply dont exist it seems? 2gbx2 has plenty, but it seems the bigger 4gb sticks can't handle a CS7-7-7 timing @ DDR 1600? DDR3 1333 have em in spades (and even @ 1.5), but not @ 1600. Do they exist?

Would DDR3 1600 C8-8-8 be equal in performance to 1333 @ C7-7-7?
 
http://www.bit-tech.net/hardware/memory/2011/01/11/the-best-memory-for-sandy-bridge

i can't see how the hell 1600 is recommended for SB.

If you skip every retarded synthetic benchmark

and go to the actual REAL benchmarks


you'll notice the gains are minimal or non existant...would i be willing to pay extra then? It depends - I got 16 gigs of 1.5v 1333 DDR3 in the SuperTalent sale....let us see 1600 DDR3 approach those prices.

even if you look at their faux 'real world tests' where they create a point system, you are looking at ~5%....


I would think that data CLEARLY suggests, "with sandybridge, unless you want to max/min every last ounce possible, don't waste your time and just get DDR1333"

Can someone explain to me otherwise because I simply don't get how so many of you are saying that it is clear DDR3 16000 should be used

I Was deciding between the corsair vengeance 8gb 1600 cas 9 and cas8 ram....on Newegg it's a $25 price difference. Since I ordered 16 gb worth, it made a $50 difference...so I ordered the cas9 version.

Good, bad?

I do mostly photo and video editing on my machine

Good. CAS 8 wouldn't do anything.
