Kingston HyperX Predator DDR4-3000 16-GB Kit Review

[Crashman]

The X99 platform is already pretty expensive. Does a 16GB quad-channel kit of DDR4-3000 memory really need to cost more than $400? Kingston takes on our previous DDR4-3000 test sample with its newer, lower-priced HyperX Predator.

Your benchmarks compare the DDR4 ram to other DDR4 ram.
Is there a way for you to give us any kind of number comparing it to fast DDR3 CL9 ram? I know you can't do apples to apples benchmarking, but some idea of the performance increase, if any. would be more helpful I would think.

Due to the different CPU, the only thing you can really compare to DDR3 articles is Sandra Memory Bandwidth. It's lower for DDR4, even when set to similar timings at the same frequencies. This is mostly due to longer secondary and tertiary timings, it appears, and will only be solved as DDR4 continues to get faster and lower-latency versions.

Pricing update at the end of the article. Expect more pricing volatility by the end of this month.

Again, DDR3 to DDR4 gaming comparison is what everybody wants.

Fudge the CPUs then (down-clock if needed), get as similar CPUs as possible, or use two high end CPUs that make the two systems GPU bound hence making the difference in CPUs irrelevant.

I'm beginning to get this feeling that there is no performance improvement between DDR3 and DDR4, and that there might even be a performance decrease in DDR4 when it comes to gaming because of the crappy DDR4 latency. And I think that because of this, sites that receive a DDR4 sample to test are told not to test against DDR3 (or no sample for you!)

Sooner or later, somebody will do this test, and we'll then learn the [UGLY] truth which the ddr4 manufacturers don't want us to know.

Linus already did it. Take a look: https://www.youtube.com/watch?v=utWnjA4NzSA

He just disabled come of the cores on an X99 chip and clocked them the same. Not 100% identical, but very (very) close.

That is one gigantic heat sink on those RAM chips. I'm taking it conventional cooling won't work with those heat sinks as tall as they are?

too many factors to consider (whether the inner slots will be filled, how close the closest-filled slot is, etc. But for huge coolers that overlap the DIMMs, no.

 

[SteelCity1981]

well this is why you don't adopt to the new gen ram as soon as it comes out because of the high cost and high latency.

 

[Hupiscratch]

It's amazing to see how fast these things became. I'm still using a PC with DDR 516 that gets only to about 2.3 GB/s. I think my head will blow when I finally buy a new PC.

I have to admit, when I first looked at that it almost looked like laptop memory.

No. Superfluous. Period.

Both are now below $350

So we should not spend megabucks on DDR4, buy instead go for more channels of RAM.

Can anyone beat my 6 channels of eBay surplus DDR3 ECC with their fancy 4-channel RAM kit?

 

[RElectrons]

Sorry about that...I was reaching over my KB for my mouse so I could ask CPU-Z for my memory timings, and somehow submitted my comment.

I meant to ask:

Can anyone beat my 6 channels of eBay surplus DDR3 ECC 1066MHz, CAS 7 (in my ancient Dell Precision T7500) with their fancy DDR4 RAM? Anyone?

MY conclusion is that, we should look at the number of channels, and ignore the allegedly low-CAS stuff.

I've never seen a 6-channel memory controller. Ever. Even in multi-CPU systems that have two 3-channel controllers, which still do not make a six-channel controller.
