RAM Voltage

post #1 of 6
Thread Starter 
Hey, making a new rig and I've done some googling but I'm not quite sure I've come up with a straight verdict. I plan on running them w/ a ASRock Z77 Pro4 i7 3770k.

I want to pick up this RAM : http://us.ncix.com/products/index.php?sku=52621
It's incredibly cheap and seems like solid RAM but its running @ 1.65V vs 1.5V which I know is above intel's recommendations. Is it a wise decision to pick these up or should I go for the $90 1.5V 12gb kits?

Most people here would say that there's really no inherent danger in running 1.65v RAM on the Z77 platform.

Be advised that the aforementioned RAM is a triple-channel kit designed for the earlier i7-9xx Bloomfield/Gulftown architecture, and as such you won't get 100% of its performance running it in the dual-channel memory setup that the Ivy Bridge i5-3570K has.

Is worth grabbing the more expensive RAM for the performance gain? Everything I've read tells me that RAM makes a minute difference in performance unless you don't have enough of it. Running a 3770k btw.

The current consensus is that 2x4GB is enough RAM for 99.44% of gamers.

As for timings, DDR3-1600 @ 9-9-9-24 is the lowest advisable, while DDR3-2133 @ 9-11-10-28 is about as good as it gets before getting into the zone of diminishing returns...

The above post is exactly what I've found from my ongoing RAM experiments.

With Sandy Bridge, RAM seemed to stop being of any real importance in terms of overclocking, as the FSB/BCLK was left alone and the multiplier simply cranked up.
However, SandyBridge-E is reminiscent of the X58 days, and Ivy Bridge has an IMC so strong it's kinda ridiculous. Both of these platforms bring memory speeds back into focus.

I have done most of my testing so far on my 3930K + RIVE setup, but I have been working with a 3770K + UP7 as well recently.

The bottom line is that IVB LOVES RAM SPEED. The difference between a good kit of 1600 with say 8-8-8 timings, and a good 2400 kit with 9-11-11 timings, is extremely pronounced. Every single thing is snappier, games run much smoother and with a minimum FPS that's 5-22fps higher, and so forth. Considering the difference in cost, I absolutely recommend getting 2133 at a minimum, ideally with good timings (9-11-10-28 is the best I've found that is available off the shelf). However, if I were buying for a 3770K setup, I would go for the G.Skill Trident X 2400 9-11-11 kit (2x4G) as it's $100 and is plug&play.

Hmm, everything I've read has stated RAM timings / speed translate to literally nothing when it comes to gaming. So I pulled the trigger on today's shell shocker and picked up two of:

I need around 12-16 GB as I have multiple games up at once; typically 5-7 at a time.
