DDR3, DDR3l & DRR4

[Zed95]

What the difference in performance wise
Is it worthy to upgrade to DDR4 Memory

Thanks

Only a few processors support DDR4, so you can't "upgrade" to it, you ahve to build a whole new PC. DDR3L is laptop RAM, so unless you have a laptop, you can't "upgrade" to that either.

DDR3l is not limited to laptops it comes in desktop sizes too. its just ddr3 that uses 1.35v.

DDR3L is DDR3 Low voltage, whose standard is 1.35 vs the accepted 'norm' of 1.5 and not tied to laptops

Edit: bignastyid beat me to it


Performance wise wise (at the same data rate and timing, no difference to speak of. Most DDR4 runs with higher comparative CLs at a given data rate than does DDR3 due to the reduced voltage

Question is Will it support Intel 4th gen processor and motherboard?

4th Gen is considered the Haswell CPUs that only run DDR3, 5th Gen are the 2011v3 CPUs and 6th gen are Skylake (socket 1151). The 5th and 6th Gen are the ones that run DDR4

So that means due to high voltages in DDR3, LGA 1151 won't support DDR3 but can support DDR3l.
Then if we overclocked DDR4 RAM, then won't the voltage reach over 1.5V?

I (and some of the mobo makers) don't really agree with that approach, there are Z170 mobos that will run DDR that they advertise right up through 1.65 DRAM, Intel's official stance is no on DRAM over 1.5, but that was also their stance on the P67, Z77, Z87 and even Z97 (1600 and up to 1.57 or whatever)

You are a mobo maker. :O
Nice

Have a question
Do you guys plan on releasing a Z170 mini itx ROG motherboard?
I am planning to build a mini itx build since I have a unopened phanteks enthoo evolve pro itx case

I'm not a mobo maker, just a builder among other things 😉, and not sure on a ROG ITX, might send a PM to raja@asus, he's the Asus rep here on the forums 😉

aah I just noticed. You have 3 Rigs.. AMAZING

Also one more question. Is it possible to lower the voltages in DDR3 memory on an other computer and then insertit in LGA 1151 motherboard?
If so would you recommend it?

Sig is a bit out of date, have sort of finalized the AMD rig (for the moment 😉 ), and I have a Z170 Hero/6600K I'm playing with now. I have a systems consultancy so the rigs are generally in use by someone 😉

Nice
My rig died due to some fault in the PSU and guess what, it took down everything (it was pretty much outdated now)
i5 750
gtx 560
500 PSU i think

Frustrated I was and started saving money.
Been 2 years now

Always invest in a good PSU 😉 Many don't think about it, but if and when they go, they can take alot with them 😉
