overclocking ram? Is it safe?

[Terabyte_272]

I have pretty generic 1600mhz ddr3 ram and was wondering if I could over clock it and to what speed safely and what power amount. if you are wondering what ram it is exactly here it is https://www.amazon.ca/Samsung-PC3-12800-DDR3-1600MHz-Unbuffered-M378B5273DH0-CK0/dp/B00BZ9ZE9C

Overclocking ram is perfectly safe, you should look up some how to guides online to get a good idea of what to look forward to.

You could overclock it, but how much is difficult to say because every stick is different.

 

create a bootable version of memtest86+, make sure you can boot into it before you start

 

Try 2133 since it's a Samsung stick, then increase the numbers for the primary timings (tCL, tRCD, tRP and tRAS) to a large number, say 20-20-20-60. Also change the memory voltage to 1.65V. Test with memtest86+ (better use multi-thread mode). If stable, lower the first 3 numbers by 1 each. Keep doing this until it crashes or pops errors, then return to the last stable number. Start touching each of the 3 numbers individually and find out how low each of them can go. tRAS, the big number, should be about the sum of the other 3 numbers minus 3-5, since this number doesnt affect performance anywhere near as stability.

So 1.65v is a safe voltage for running the ram at 2133? I mean my oc cpu is at 1.45v at 4ghz

The Reason I want to over clock my ram is because my systems ram is preforming really far bellow average on user benchmark and on there it says its running at 800mhz even though my bios says its at 1600mhz.......

DDR ram sends data twice per clock cycle, so 800MHz is the clock cycle, 1600MHz is the data rate
