CPU-Overclock and RAM-Settings

[Tia]

Hey all,

i've got interested in overclocking my cpu to get some better gaming experience. I've watched the tutorials on the channel and got to the results of 4,3GHz@1.225V on my i5-4670k.

There are several different questions now.

 

1. I've tested the system stability for 120 minutes with Aida64, half an hour with prime95 small fft v266 and  played Black Desert Online and Overwatch several hours straight without any crash.

what i noticed is, that the VCore gets pulled up to 1.3V sometimes while playing. I have set adaptive Voltage with LLC on "Regular" (Asus z97-k Motherboard).

 

Q: is 1.225 / 1.3V reducing the lifespan of the cpu already? if yes, by how much? is there anything to eliminate the 1.3V?

 

Also about the temperatures, as i have a sh**** case with some old case fans, the airflow isnt rly that good. so the temperatures whith the benchmarking (Aida64) got me around 70°C core temperature and close to 50°C cpu temp. While playing i got temps of mostly 70-80°C Core temp. The Cpu sensor says its at about 60°C while playing.

I'm cooling with a Katana 4 Air cooler.

 

Q: are these temps to high? do they reduce the lifespan of my cpu, or by how much do they do? should i better reduce the clocks to be able to apply lower vCores?

 

 

2. While i was in my Bios i had a look at my Ram bec. everywhere i read to take into consideration of overclocking my ram for more performance. So i have a set of old ram, and a set of kinda new (2years or so) ram. i have 2 of each in the slots. https://www.kingston.com/datasheets/KHX1600C9D3_4G.pdf http://www.kingston.com/datasheets/khx1600c10d3b1_8g.pdf

Q: As the rams have different specs. how should i set my rams? the one module states its tested for 1.5V, but i ran it with 1.65V bec. of the xmp profile that was loaded. My system is actually running with 1.65V and 9-9-9-27 timings for these 2 years without any problem. I just thought the 8GB rams would get hot, to hot, or anything bec. of the 1.65V? should i better take out the 2x4GB? should i rather set them to 1.333GHz with these timings? or let them stay at 1.6GHz with some higher timings? What should i do about the Voltages? do they run to hot with 1.65V? whats the best method to check that? do rams also have thermal safety shutdown or will they just break if they run to hot?

 

 

(the html is a list of cpu/ram information in my system)

 

If you need any additional information, i will reply as fast as possible.

You need to get those temps down either a new cooler or lower volts

Ok im running the rams with 1.5V now, i made a 20 minutes stresstest with aida and played a few hours and no crash so far, think its stable with only 1.5V. I think its correct that the ram doesnt take any damage from to less Voltage, right? so as longs as i dont get a crash, i can reduce the voltage from RAM and CPU?

ok i got back to my pc and continued tinkering. I put the clocks down to 4.2GHz bec. im not sure how warm the cores are allowed to get without killing the cpu within a few years^^

having 4.2GHz@1.155V, it crashed after 5minutes with 1.15V but i havent tried anything between that yet.

10minutes stresstest for the temps got me:

prime small FFTs with closed case: cores ~82°C, cpu 53°C

Aida64 with closed case:                 cores ~65°C, cpu 47°C

still looking forward to hearing advice from a pro here ^^

 

Also update on the ram with only 1.5V and the said timings: still no crash when gaming or rendering/converting video
