[QUOTE=Mark Rose;460138]I suggest the Arctic Freezer i11. I'm using 10 of them on various systems. Its fan is quiet and has a fluid-dynamic bearing that won't wear out for a long time. It's inexpensive and will fit in most cases. Most other <$25 coolers have cheap fans that will die in a year.[/QUOTE]

If the fan is detachable, and it appears to be, that would be a great help with cleaning. The dust here is terrible. I won't go into the floating cat hair that goes everywhere. :smile:

[QUOTE]You really do want dual rank memory. You'll get about a 10% performance boost. Many (all?) 16 GB DDR4 sticks are currently dual rank. From what I've observed it matters more than using slightly faster clocked memory. It seems dual rank memory can fetch and store memory faster since it is interleaved across more chips. Dual rank modules will almost certainly have chips on both sides of the PCB. CAS latencies, etc., don't matter.[/QUOTE]The Kingston [U]Fury [/U]lineup states dual or single rank in the spec sheets

I am running 8 GB modules, which are rated 2666MHz, at 3200MHz without problems.
Unfortunately, the spec sheets are not coming up on some parts.

[QUOTE=storm5510;460103]I found a single 16GB Corsair DDR4-3200 module. Perhaps a good place to start.[/QUOTE]

Remember to get at least 2 RAM modules and place them in slot 1 and 3 for dual channel memory. That is a lot higher speed boost from dual channel than from dual rank. If you only want 16 GB total, then get 2 x 8 GB if you can find it.

Yes, it comes off easily. You'll need to take it off to install the heatsink.

[U]I just ordered the i7-7700. This was the "big bite."[/U]

Any heat-sink and fan combo I've had in the past was always a pain-in-the-rear to clean. It usually involved taking all of it off the CPU.

Finding DDR4-2400's have not been an issue. I'll change it to two modules. I can, and probably will, add two more later on.

[I]Kingston Fury[/I]. I remember seeing those while I was digging around. I'll take another peek.

Thank you all for your input! :smile: :smile: :smile: I will be back with more later on.

I like Noctua coolers, which do well on tests and IMO are designed thoughtfully (unlike some of the cheap ones I used to use, which work fine but were a nightmare to install). But they're not cheap.

For cleaning, I've found our Miele vacuum cleaner useful, as it allows the tube to be connected to the exhaust side as well, which allows an air stream either direction. After using it normally, I set it to blow air and it gets a whole lot more dust out, including cleaning up between the cooler fins. An alternative might be one of those [URL="https://www.amazon.com/Giottos-Rocket-Blaster-Blower-Large/dp/B00017LSPI"]rocket blowers[/URL] (I used to have one for photography, but lost it). They're not very expensive and it's useful for lots of things like keyboards as well.

And it does look like a rocket. :smile:

I looked at some Noctua coolers after doing a web search. Yes, they are a bit pricey.

I've done a lot of shopping around today with my parts list and compared costs on everything. It's a mix of vendors. However, I was able to save roughly $60 USD. As a result I can say that [B]everything is ordered[/B].

I received a partial shipment today. The case is designed to hold five 120mm fans. Two in the front, two on the side, and one in the rear. The air filter in the front cover can be removed for cleaning. It will catch things like lint, but fine particles like dust, will go through. I have something here on a roll that I can supplement that with. Spun nylon, I believe it is.

I have the CPU, the CPU cooler, PSU, and the RAM. The main board will take a bit longer. It is said that one should frequent local businesses, and I did, for this. The owner and I went to the same local college. He doesn't keep much stock in the way of motherboards, I gave him the brand and model number and he gets on a phone and calls his distributor. Two days, he told me. He calls me this morning and says his distributor was out-of-stock on that particular model. They are expecting a delivery next week, from the Far East. I won't be going local again!

[QUOTE=Prime95;460087]The Z motherboard lets you overclock memory. The B does not. Since prime95 will be bottlenecked by memory with that CPU, I'd go with the Z and some DDR4-3200 (or whatever the sweet spot is right now).

Though I have no personal experience, several have reported benefits from dual-rank memory. You'll need to do some digging to figure out if memory is dual rank -- the info is not easily accessible.[/QUOTE]

Is the DDR4 also the bottleneck at that cpu at FFT sizes needed to prove 5-6 mbit numbers?

On the PSU realize that PSU's get their optimal efficiency at around 50% load.

So if expectation is you are gonna burn 200 watt, then a 400 watt gold 80%+ rated psu is ideal.

A 800 watt psu however is far far from optimal for a 200 watt eating system under fulll load. As the efficiency underneath say 40% of the psu goes down quite a lot.

I do own platinium psu's here as well as gold ones and there really is hardly difference.

Most efficient is keeping the CPU at room temperature (that usually is easiest with simple watercooling and hanging a fan above the motherboard blowing air onto it.

At temperatures like 50C+ the cpu eats easily 10%+ more power than at room temperature. Identical number of degrees underneath room temperature it also eats 10% more power for modern CPU's.

Very old CPU's had no problem getting cooled at freezing temperatures. Modern ones do.
