G.Skill's Ripjaws 4 DDR4 Memory Hits 3200 MHz, 64 GB

By - Source: Tom's Hardware US | B 25 comments

G.Skill officially announced its complete Ripjaws 4 DDR4 lineup.

We already sawG.Skills Ripjaws 4 modules listed on OCUK a couple of days ago, but now G.Skill has officially made the announcement, detailing all of the specifications and kit configurations.

The DDR4 modules are meant to be used with the upcoming X99 platform and Haswell-E processors and will run at 1.2 V for those operating at or under 2800 MHz, while those operating at 3000 MHz or higher will run at 1.35 V. Officially, 1.35 V is outside of the DDR4 specifications, but anyone running memory at these speeds won't be too concerned with the extra power consumption.

G.Skill's Ripjaws 4 modules will be available in frequencies ranging from 2133 MHz through 3200 MHz. They come with CL15 or CL16 timings, and DIMMs will be available in 4 GB and 8 GB variants. Mind you, you won't be able to buy individual DIMMs; kits will be available with capacities of 16 GB, 32 GB, and 64 GB, although some higher-frequency memory won't have all the kit options. The 16 GB kits will consist of four 4 GB modules, the 32 GB kits of either eight 4 GB modules or four 8 GB modules, and the 64 GB kit will come with eight 8 GB modules. All of the kits should be available with red, black, and blue heatspreaders.

No word on pricing or availability yet, though we do expect the entire platform, which includes the X99 motherboards and the Haswell-E CPUs, to hit shelves on August 29.

    Well, I'm on my 3rd dying set of G.Skills Ripjaws DDR3 F3-12800CL10Q2-64GBZL. Make sure it has the lifetime warranty. Over 25 years I’ve never seen that with RAM before, kinda scary.

    First DDR4 worth buying. Need to cross the 3200mhz barrier to be viable.

    Current DDR4 timings make me less than excited for the first generation of offerings...

    From a business standpoint I can only assume its because they expect not to have to replace as much. Could be wrong.

    Timings could be better, but capacity is nice at least. Really between the two I'd rather have more capacity at this point anyway.

    Capacity is nice timings aren't too fantastic, but still good enough entry point.

    3rd set? must be something on your end. i've been using 1 set for years and so have people i know. no issues.

    Same here. I've been on my first set of G.Skill 4x2 GB 1600 MHz for 5 years without even a hint of problems.

    Viable for who? As far as I am concerned even the cheapest 8 GB DDR4 kit currently available would be more efficient, faster, and cheaper than my 8 GB of DDR3 1600 that I bought 5 years ago. For me, it will be a serious upgrade for my next PC build. It is very "viable".

    I have seen so much whining about the timing, yet even the slowest DDR4 is faster than what 99% of people have.

    Just ordered the G. Skill 32GB kit. Now the wait for MB and CPU to come online.

    Out of curiosity, what are the perils of higher than spec RAM voltages like those?

    Timing will be about twice DDR3 timing. This means the data will have a higher latency, thus slower. You compensate for this the same way it was compensated in DDR2 to DDR3, double the frequency. This means if you are running 1600mhz DDR3, you should be looking at 3200mhz DDR4.

    Timings are proportionate with base clock rate. Since this is first generation of a new technology you can expect the CAS refresh to be more lose then what will come later once the process matures. Before directly comparing products always convert the latencies from clock cycles into nanoseconds.

    http://en.wikipedia.org/wiki/CAS_latency

    DDR3-2133 CL10 has lower latency (9.38ns) then DDR3-1600 CL8 (10ns). So DDR4-2400 with CL15 would be 12.5ns and DDR4-3200 with CL16 would be 10ns. Also having a higher voltage helps lower your CAS due to being able to charge / discharge faster. I'm willing to bet the reason for the higher latency on the lower models (12.5ns) is due to them wanting to maintain lower voltages (1.2v) and thus less power usage for low power devices.

    That is not how that works. Timings are measured in cycles which is a component of the bandwidth. DDR3 has a higher base clock then DDR2 and thus requires more cycles to charge / discharge the lines. There is a physical limit of about 7ns on really good silicon with most being in the 9~11ns range for charge / discharge times. No matter how much you increase the bandwidth or clock rate you won't be able to charge / discharge the capacitor banks faster then that.

    And FYI, DDR2-800 CL5 had an absolute latency of 12.5ns while DDR3-1600 CL9 has an absolute latency of 11.25ns. The DDR3 actually has a lower latency then DDR2.

    No 16GB modules? Unacceptable!! Been waiting for those for years to come out.

    At this point DDR4 = money on the wind. Its not faster it has the same capacity and even the same power counsumption if you want it to be alittle bit faster.
    There is no point in it until they hit atleast 16 GB per stick and next I7 extreme won't support atleast 128 GB of ram.

    Well these are not 4x2 GB they are 8x8 GB, more density more problems? I don’t think I’m holding it wrong. :)  But what would I be doing to kill the RAM? No overclocking, I’m just doing what I’ve always done and never seen RAM die like this before. Others in the Newegg reviews said they had it die on them in a few months. I’m on my 3rd X79 MB upgrade, new Asus Deluxe and using default XMP settings. The PC is my work and HTPC so it gets a lot of use and I see the issue first in large 15-20GB ISO files. Everything looks and works fine for a little less than a year and then there will be corruption in the movies. I can only see it while watching the whole film as there will be just a few glitches in the video and it may be months before I watching the movie after copying it to the PC. Once it’s starts to die I can take the ISO files and make a copy and do a compare in ImgBurn and there will be random miss compares. I can put in my single 8GB test DIMM or copy the file to my old PC and copy as many times as I want then do the compare successfully.

    I think a lot of folks don’t know their RAM is going bad. Apps like MemTest86 do not see an issue but Prime95 starts crashing and I get the file corruption. If I replace the RAM and all is good again... for about a year. :(

    I'm sorry, how is it going to be better? Just because it has a 4 at the end and not a 3 doesn't mean it's better. Current DDR3 will be better at 1600, as you can get CL of 8 or 9. It will absolutely in NO way be an upgrade. It'll actually be a downgrade in performance - technically speaking.

    could be because it is so much ram. i would know if my ram was going bad though
