1070ti bottleneck or other issue

[Shreyash_1]

Hello
I just purchasef a 1070ti liek yesterday as my 970 died, not while playing rainbow six siege, my gpu performance drops from 120 fps to 60fps (between this range) with my settings same as that of the 970which gave me constant 970 . Also my cpu usage goes 90% close to 98%.
And ram also is used 70%
Wanted to know the cause of this do i need a cpu upgrade or a extra ram

Specs
Gpu-strix 1070ti
Cpu-i5 6600k(not overclocked yet)
Ram-1X8gb corsair vengence(other one lended to my brother will be getting it back soon)
Game on samsung 850evo 512gb

Please help

do a complete reinsall of nvidia drivers.

you may want to oc your cpu to 4.3-4.5 range and ram looks fine for at the moment.

Ram usage is not what you think.
Windows keeps unused code in ram in anticipation of reuse.
If you truly have a ram quantity issue, it will show up as a hard fault page rate that is significant. Perhaps > 1 per second.
8gb should be enough unless your are multitasking while gaming. 16gb is almost certainly good.

More importantly a single channel of ram will slightly reduce your cpu performance.

If you have a z chip motherboard, go ahead and overclock. You are leaving some 25% cpu performance on the table.

90% cpu usage certainly indicates a cpu limitation.
Why your performance drops with a stronger card is a mystery.
Have you reinstalled your graphics card drivers?

No I haven’t reinstalled For that matter I just got the card yesterday ya and yea my motherboard is a z270f strix version . And is oc of the cpu safe ? Like wil it harm my cpu over the long time? Also my gpu is a day old , and have installed the latest drivers from GeForce experience yesterday. I do use hyper 212 led for cooling so will this effect the oc cpu temp ?

 

[zyh1987]

for drivers, you want to manually removed it, and reinstall,
i found nvidia experiences tends to be problematic from time to time.

as for oc, you can safely push it to 4.2 with no issue, i have a 6600k with hyper 212 led, 4.5ghz. with reasonable temps.

How well you can OC a 6600k will be determined by your luck in getting a good chip.

As of 12/04/2016
What percent can get an overclock at a somewhat sane 1.40v Vcore.

I5-6600K

4.9 14%
4.8 38%
4.7 67%
4.6 87%

The easy thing to do is to gradually raise the all core multiplier from the stock 35 to higher number, leaving all voltages on auto.
Stress test with something like OCCT, realbench, prime95 or whatever.
Monitor your temperatures and vcore.
CPU-Z is good to monitor vcore. The key to longevity and safety is to keep vcore under 1.4v.
A stress test should not go past 85c.
When you feel you have reached your limit, back off a couple of notches.
Under normal heavy usage, you will never reach the stress test limits.
Lastly, implement speedstep.
That will reduce the multiplier and associated vcore when the cpu is not busy.
When you think

Someone told me since I had changed the gpu a clean install of windows with reinstalling or updating of the drivers will solve the problem? Wil it actually solve the problem?
