? about memory occupied memory slots while running HDET mobos

post #1 of 4
Thread Starter 
To start off my good ole I7 3930k is show her age. Taking a hair more voltage to hold it s4.7ghz. I actually just dropped my oc down to 4.6ghz, hoping it will hold out til Skylake-e in 2017. If not I may settle on the I 6950x(Broadwell-E). Anyways I am in the planning stages, try to see what the total cost are gonna be to get this new build up and running. At this point I am running only 2x8gb sticks in my x79mobo. I hear that is pretty inefficient but all my other ram slots are going bad(another reason i know a new build is in pretty dire need here soon). It was all i could get to work while holding a respectable 1866mhz overclock and the only other option was 3 slots and I didn't have matching memory. I figured it was just going to hurt me more than anything.

So lets get down to the question at hand. I am going pretty ballz to the wallz this time around. I want pretty much everything to be best or dam near the beast. So I am going over possible memory configurations and trying to get a estimated price. I see 3 kits that I like. My budget is 200-250$ may stretch it to 300$ if it would give me a good little boost.

Kit # 1 this one seems to have the best timings and be the most top rated yet is only dual channel.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820232206&cm_re=ddr4-_-20-232-206-_-Product -- price 264.99$

Kit # 2 this one is definitely cheaper, still has decent timings and is quad channel.

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231942&cm_re=ddr4-_-20-231-942-_-Product -- price 194.99$

Kit # 3 this one is yet again dual channel but would allow for possible future quad channel @ 64gbs of ram and holds same timings as Kit 2 which is decent.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820232091&cm_re=ddr4-_-20-232-091-_-Product -- price 214.99$

Now I do tend to run servers, sometime 2 at a time. I also do some video encoding and music encoding. Some modding i do, eats through memory resources like crazy. That is why I am opting for I7 extreme and would like to up my memory count to 32gbs. I also am a hardcore gamer so I want the best of both worlds and when it comes down to it I would prefer best game performance over the servers and encoding. I am a little more advanced than i was last build but still don't know what cas latency is or how it works. I know lower is better but not sure how that works out in my needs. I also understand lower timings is better but also don't know why or how much of a difference that makes.

Now the reason why I am asking which is better out of these kits is, I was told that on my current set up I am hurting myself and losing memory bandwidth speeds with only running 2 dimms. Is this true in regards to x99 motherboards or if my pc makes it whatever scheme they use for skylake e. So in short do I need to get a quad kit to get the absolute most performance or is a dual kit not going to make any difference.

Also I don't have to go with those kits any suggestions are welcome, as well with any suggestions on any other aspects of this build.. Just keep in mind I am looking to build the absolute all around fastest computer I can at the time I pull the trigger. I will have a pretty high budget as well when I do make the jump so if there is something a little more expensive that will give me a notable performance boost bring it on. Keep in mind gaming is priority, yet some of that requires the extra cpu horsepower, memory amounts and speeds when running my servers.

P.S. Reason I put this in the intel mobo section was my question regards to memory efficiency and performance on how it is configured on motherboards.

Quad channel is twice as fast as dual channel so going quad channel is more important than speed for bandwidth. I have had trouble running dual channel kits as quad channel kits, usually you have to relax some timings before it works, so I recommend not getting dual channel kits for a quad channel board.

X99 has quad channel memory so for X99 I suggest something like:

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231857
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231802
or
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231930

You can think of latency as timings / speed, this means that 2400 12-12-12-28 (12/2400 = 0.005) is quite similar to 3200 16-16-16 (16/3200 = 0.005). For gaming we like low latency but do not really need more bandwidth because quad channel offers a lot of bandwidth already. Running 2400 at CAS 12 is almost exactly the same for gaming as 3200 at CAS 16. Getting 3200 at CAS 14 would offer a small benefit but it is hard to get stable, especially on Haswell-E.

I am quite happy with my 32GB 3000-15-15-15-35 quad channel kit running at 2400-12-12-12-28 1T. This isn't anything special but it offers great performance, was easy to get stable and the price was very reasonable.

Just for your information Haswell-E likes 2400 a lot but some CPUs can be trickier to get to run 3000+ stable.

Well i was able to get my cpu stable again lowered cpu clock speed to 4.6ghz has ran fine with my same 1.335 or 1.34 volts vcore. Sorry cant remember which it is. Anyways i really thought my 3930k was going to die on me. I guess she is just getting up there in age and needs to slow down a 100mhz. With that in mind i am gonna hold of on haswell e and hell probably 2even broadwell e. Just get the laste 1-2 years out of here until skylake e hits. It seem to be bringing some bigger changes to the table. My pc kept bsoding because the cpu wasnt getting enough volts. I thought for sure it was gonna die here soon. Hopefully it can hold up to at least 4.4ghz til skylake e release.

Sorry i dont think i mentioned the reason i was asking about memory layouts was because i feared i may have had to upgrade soon.
