Help would be appreciated here please. I'm looking to get a PC built for me, looking at PC specialist at the moment and i have a few questions. Any comments on the below would be appreciated. (Also alternative suppliers, I'm looking at PC specialist because they built my last one and I'm still happy with it, but I'm not stuck on them)

 

I'm looking at a 7820x, with the intention of OC'ing myself, but with the build being done for me

 

Mobo wise cheapest option is an asus prime x299A, there's a couple of asus ROGs, and a couple of gigabytes available too at extra cost, but as far as i can see, the x299a offers all i need. 

 

Memory wise, DDR4 @2666Mhz is the max un-overclocked memory. My previous research into OC memory told me that memory was a minor improvement, and probably not worth bothering with, am i wrong here?

 

intel optane memory is available as 16 or 32 gig units, but I'm struggling to work out what the difference is, or how they are used differently to an SSD. Wiki doesn't seem to help much here. My best guess is its a new form of RAM, but i cant work it out. At this point I'm leaning towards ignoring it entirely.

 

The real area I'm looking for help in is cooling. with a view to OC, and the fact that the mobo appears to produce reasonable OC's by default (almost) I'm thinking more processor cooling is in order. I'm not that bothered about noise, just cooling. It looks to be quite complicated to work out how much cooling is required, especially not knowing how much heat will be produced. It is only the processor i intend to OC, the GFX can stay stock

 

Is paying extra for more expensive paste really worth it ,upgrade cost is £9 so immaterial in this build, but i resent the thought of being conned

are extra case fans worth looking into?

 

As an aside, i have built my own before, but cant be bothered/don't want the risk of getting something wrong as this will not only be for gaming, but for working on. No PC = no money earn't, big price to pay for a bit of fun :S

 

many thanks all :)

assuming you need a 7820x over a 8700k. i think you;d be better off with at least an AIO loop to cool it if you plan on overclocking. Defo get a double slot if your case can hold one a nice 240mm rad and dual fan will be fine. coolermaster ml240 has had good reviews for the price, or if u got a massive case look for a triple slot design. but it'd have to be at least a 2 slow cooler and defo not a HSF air type.

Now back up, put the gun down, and get me a pack of Tropical Fruit Bubblicious. And some Skittles.

So i have the Aio cooler, and have a OC of 4.3Ghz, and all seems fine, i think.

 

normal temp of the cpu package is about 54C, with max at 65C, hit today with ambient temp of 26C. What is a sensible top temp to aim for, can i go faster?

that's not half bad. im genuinely surprised by those temps for a 7820x. which AIO cooler did you go with in the end ?

Corsair H80i. What are your thoughts on reasonable cpu temps Dibbz?

with the base turbo clock speeds for mostly every CPU anything under 60c even with slight dust collection it should be bellow 60.

 

but you are using a 120mm AIO cooler id say roughly 74c is the threshold id feel for that CPU. considering its threshold is 99c

just to add a bit here i find 32 to be a pain in the ass to overclock don't think its needed for games without memory leeks 

 

also when i went 32 i had to upgrade my os to pro i think

might push it up a bit then Dibbz, cheers

 

mixe, you have lost me with "32" ?   But I'm genuinely finding the OC useful in big Stellaris solo maps, much faster to play hence thinking about going further (Stellaris maxes out a single core, with maybe 5% use of the other 15...)
