PC Build

Postby M0GXZ on Tue Jun 12, 2018 10:20 pm

It’s been years since I built a PC but I think the time is right for a new one.
I’ll re-use my old case and PSU ( after hoovering the dust out).
Think I’ll go for AMD this time.

You might want to check the connectors and current ratings on your PSU, they've changed a bit over the years. Not sure how old this box is.

Luckily I bought a decent PSU last time as I’d realised the only thing I’ve ever seen to break on a PC was the cheap PSUs that come with cheap cases.
Previously I’d used the 4 pin CPU cable but it has an 8 pin cable for the new motherboard.
Don’t need gaming grade graphics so I think I’m going to be ok on that front.
I’m choosing a cpu that isn’t too hungry for watts.
Reading about M.2 modules- astonishing read & write speeds.

Yeah M.2 is definitely the way to go, don't even consider anything else.
If you really need lots of storage get a second spinning hard drive but definitely use M.2 for your main disk.

One thing people often fail to consider when buying hard disks is that the power consumption difference between SSD's and HDD's is huge. Any money you save by going spiny instead of SSD will be lost to electricity bills, not to mention spinning disks have a ~10% failure rate in the first few years.

One of my motivations for building a new PC is that I just happen to have a 500GB SSD needing a home.
So maybe a modest sized M.2 for booting and programs and the SSD for data.

The m/b I’ve chosen can take 64GB of RAM over 4 slots,
that would cost over £700 to fill but I’m thinking 16GB will be enough.
I will be using it for SDR so more memory will mean more virtual radios subject to CPU.
The CPU I’m looking at has 6 cores/12 threads.

Ahhh, depending on what you have the jump to M.2 may not be worth it. If its a Samsung 840/850 or a SanDisk Extreme I wouldn't bother with the M.2. There is a difference but they will be plenty fast enough.

With reference to RAM yeah 16GB is the sweet spot IMHO. I run virtual machines and everything in that, I am using Linux to be fair, not so sure about Windows these days but I think 16GB is still a good number.

Although saying that if you can have one disk for data and one for the OS it makes life a lot easier at re-install time :)

Just adding a vote for 16 GB RAM being a realistic maximum you should aim for.

If you were being tighter on budget 8GB is actually more than enough for most use cases - whilst leaving you with an obvious upgrade path if needed.

Depends what you use the machine for.

[Use windows on my machine with 8GB and i push it a lot and have no issues - to be honest I would only use 16GB if using virtual machines or some memory intense graphic work etc... also +1 for linux - if it could just run a few more games i would use it all the time - all non gaming machines in the house have it]

Yeah I totally agree, if you don't run VM's or do heavy video 8GB is fine. I have plenty of boxes still running 8GB without RAM issues.
