I searched a bit on google about safe DDR3 voltage values and got a bit scared because some ppl sad that you can damage your CPUs memory controller if u run a memory with 1.65v.

So as i have KHX1600C9D3/4GX witch runs on 1600mhz and 1.65 i thought it would be safer to downclock it to 1333 and 1.5v so i first used aida64 to check the voltage and to my surprise it was 1.5v but i thought it was an error and booted into bios to adjust it and even the bios showed something 1.485 don't remember the exact value but it was below 1.5 a bit , there was a option besides auto and it was extreme memory profile when that was checked my ram voltage went up to 1.65 but i changed it back to auto , so am i safe running 1600mhz with 1.5v is there and degrade in performance ? I dont care much if my ram dies its not really expensive but i don't want to buy another CPU because it wasn't cheap at least for my budget.

Here is a SS of aida and cpu-z

EDIT:
My system
CPU : AMD FX 6300
Motherboard: Gigabyte GA-970A-DS3P
GPU Nvidia 450gts
DDR3 ram : 1 stick 4gb Kingston HyperX KHX1600C9D3/4GX
PSU Chiftec 750w

They will run OK, big thing is there should be no need to run 1.65 with entry level 1600 sticks, it can be indicative of them using weak memory chips better suited for 1066 or 1333 sticks.....about 85% of all 1600 sticks run at 1.5, even the high performance CL7 and CL8 sets


Hi there!

Straight to the point here, don't worry about the voltages they are absolutely fine at 1,65v. Kingstons HyperX Genesis ram is fully compatible with Intels XMP and it isn't about to die or anything. First of all, for clarification on XMP and how it works, see here http://www.intel.com/content/www/us/en/gaming/extreme-memory-profile-xmp.html

The Intel® Extreme Memory Profile

Intel® Extreme Memory Profile (Intel® XMP) allows you to overclock compatible DDR3 memory to perform beyond standard specifications. It’s designed to enhance the gaming features built into Intel® technology–based PCs. If you like to overclock and squeeze as much performance from your PC as possible, then memory based on Intel XMP gives you that extra edge you need to dominate—without breaking a sweat.1
How Intel XMP works

Predefined and tested Intel XMP profiles can be loaded via BIOS or a specific tuning application through a computer’s operating system. Often the easiest way to load Intel XMP profiles is using a tuning utility, which may be available depending on the particular board manufacturer. To learn whether a tuning utility is available on your system, you should contact the board manufacturer.

And taken from the Kingston webpage for your ram found here http://www.kingston.com/us/memory/hyperx/genesis

Compatible with Intel XMP auto-overclocking function (available with selected models)
1.7v–1.95v voltage range for dual channel applications for AMD based systems and Intel chipsets older than X58
1.65v voltage for triple channel Intel Core i7 9xx series applications
1.65v voltage for dual channel Intel Core i5 7xx series and Core i7 8xx series applications

So you see, there is nothing at all to worry about with your ram running at 1.65v :) I hope that helps to ease your worries.
 
Thanks for the reply , i am not scared of my ram dying but my CPU . I read on some forums that the lifespam of your CPU will be much shorter if you use ram with 1.65 voltage and that safe value is 1.5v but atm my ram is working on 1600mhz and 1.5v but the CL is 11 instead of advertised cl9, now the performance of CL11 and CL9 inst probably noticeable but is my CPU and motherboard safe by running with 1600mhz 1.5v CL11 instead of CL9 1.65v whats the safer option to use.
 


On Sandy Bridge and Ivy Bridge tests have been run that say that up to 1.65v has no detrimental effect on the CPU 's lifespan. You can feel free to run your ram at whatever settings you like as long as you don't exceed that limit. :)
 


Ah I see. I gotta be honest and say that I don't have any personal experience with AMD chips, nor the effects of overclocking nor voltage increases on them. However, having had a good thorough look for any issues cropping up for other people, I cannot find any evidence of such voltage increases having a negative impact on the day to day operation of, nor the life span of the AMD 6300 processor.

As I say though, I have no personal nor professional experience with AMD's products, so you may wish to consider checking the AMD section of Toms Hardware.

Yea its a bad ram and i didn't really know about it much , i wanted to buy a 1333mhz 1.5v but the dealer convinced me that the 1600mhz 1.65v was better, so its labeled as cl9 1600mhz 1.65v but if i use auto voltage on my mobo it runs with 1.5v 1600mhz CL11 when i turn on extreme profile it runs on 1.65v 1600mhz CL9 speed , so what do you suggest i do ? Leave it on 1.5v CL11 or use extreme profile and run it 1.65v so i can get CL9? I don't have much money and i want this system to last as long as it can .

And guys thank you so much for your replies, your a great help, on my previous forum i got just insults but no help.

 


Toms is an awesome place to be :) My advice, if the system isn't too old, would be to go back to the dealer and get different ram if it will make you feel more comfortable (and to be honest he shouldn't be trying to push sub standard stuff anyway), but other than that I'd stick with the 1.5v CL11 and save yourself the worry.
 
Thanks for your replies again , hard to pick just one as the best answer , so i should be safe with 1.5v CL11 i am still scared to run it on 1.65v but i will probably try it soon , i cant return the ram the store doesn't accept that i already asked 🙁
 
Ah just tried to run it on 1.65v for CL9 and used aida to bench it , 71ns latency is with CL11 and 64ns with CL9 not a big difference i think, but when i tried aida stability test with 1.65v cl9 my PC restarted 🙁 so 1.65v wont run stable , i hate the dam PC shop owner and i hate myself for listening to him. The worst part is that i will need to expand my ram soon and buy additional 4gb, but i don't know what ram to buy if i buy a different ram will it work ok with this one , i will probably buy the same one i currently have it was 44euros and even if a buy a better ram it wont work faster then this one because the dam cl11 will hold it back. Anyways thanks for your help guys i am off to sleep now good night.
