[SOLVED] Will my system bottleneck?

[Skudd]

Hi there. Planning to buy the 2070 super and I have a i7-6700. Do you think this is a bottleneck?

Monitor resolution?
Do you have dual channel memory?
Give some examples of games.

1440p monitor. I'm planning to upgrade for red dead redemption which I know has uncertainty around it and what it will need. No 100% on dual channel memory. How do check?

 

[Phaaze88]

You don't know if you have 2 sticks of ram? Some one else built it?

 

[Skudd]

Oh I thought dual channel memory was something else lol. No I dont atm but I'm planning to buy 1 or 2 more 8gb sticks. I have one currently.

While the 2070 Super is perfectly fine for 1440p, you need to fix that one stick of memory. It will cripple cpu performance in cpu heavy games/situations - your fps lows and avgs are worse, and the cpu simply isn't running at 100% without dual channel.

-Memory is only guaranteed to work as sold
-Sticks added later, even if they're the same brand and specs, can still fail - it's simply the combo with the highest compatibility rate
-The symptoms of incompatible memory don't always show up right away: freezing/crashing, stuttering, and BSODs

 

[Skudd]

So what do you reccomend I do? Is it common for memory to be incompatible?

 

[Phaaze88]

Mixing memory is always a crapshoot. Sometimes it works, sometimes it doesn't.
The best option is to buy a new 2x 8GB kit and try to sell off the older stick.
You're welcome to try adding an identical stick, but there are no guarantees.

Awesome thanks mate. So I'll buy two new 8gb and try the three together if I have issues I'll sell the old one?

Yes, but does your motherboard support a Flex Mode for memory? If it doesn't, using 3 sticks will make the cpu run in single channel.

 

[Skudd]

I'm not sure how to tell if it does? My motherboard is the gigabyte Z170-HD3-CF.

 

[Phaaze88]

gigabyte Z170-HD3-CF

Nope, no Flex Mode. Installing 3 sticks will make it run in single channel again.

 

[Skudd]

okay thank you. So ill just put two new ones in then. Do most newer motherboards have this flex mode feature? If so how do I check? Do you think that motherboard is due for an update in the near future? (2 years)

 

[Phaaze88]

Newer motherboard do have this feature and it'll be listed in the motherboard manual, or mentioned on the online motherboard product page(sometimes).

No need to change the motherboard until your current cpu fails to satisfy you, after which you'll likely need a new cpu/mobo/ram combo anyway.

Thank you for all your help and advice. Really appreciate it! So often when you upgrade cpu do you want to change to whole lot? Sometimes if motherboard is compatible you can just upgarde CPU, Correct?

There's only one other cpu you could possibly upgrade to, and it wouldn't be a real one at all - the 7700K, which is, in all essence, an overclocked version of your 6700K.
8th and 9th gen Intel cpus aren't compatible with the current mobo - those are LGA 1151 V2(the V2 part isn't present when you're actually shopping for the cpus, but that's what they are).

Well, you don't need to replace the memory. All the current stuff still uses DDR4.
