Concerns about 1.65v RAM on a 1.5v mobo

testudoAubreii · Mar 3, 2014

Hello everyone,

I just ordered this:

Kingston Technology HyperX 8 GB (2x4 GB Modules) 1600 MHz DDR3 Dual Channel Kit (PC3 12800) 240-Pin SDRAM KHX1600C9D3K2/8GX

Gigabyte Intel H81 Mini ITX DDR3 1600 LGA 1150 Motherboard GA-H81N

Intel Core i3-4330 Dual Core Processor 3.5 2 NA (BX80646I34330)

I did not read until I ordered it that the memory voltage on the mobo is at 1.5v and the RAM is at 1.65v. I am worried that I ordered the wrong RAM. Will it work? Will it damage anything if I try? Should I return it and get 1.5v RAM?

Also, I got this from the Gigabyte site. It is a list of supported memory. If you copy KHX1600C9D3K2/8GX and paste it in "Find", this memory I ordered is on the list. However, It doesn't say anything about the voltage.

Thank you in advance for your response, help and suggestions.

Though, Haswell has recommended voltage of 1.5v but you'll still be able to use this RAM on mobo and cpu without any problem. No issue there and as you are not overclocking so you are safe there.

Good Luck

I would return and get 1.5v RAM sticks, or you could drop them in the setting to 1.5v. But I'd return the RAM.

I don't want to do anything in the BIOS. I guess the path of least resistance is to just order 1.5v, correct?

You can order 1.5v RAM still you are ok with 1.65 v RAM. Choose whichever is comfortable for you. There is no issue in either selection

Can go either way, a high voltage need in what amounts to entry level sticks (1.65 vs the standard of 1.5) can be indictive of weak memory chips, about 90% of all 1600 sticks are rated 1.5 or less.......1.65 can also add more unneeded heat

this is not an answer it's a question i built my own pc this is it

processor core i5 4460 quad core 3.2 cache 6 m
motherboard gigabyte h-81 s2ph
hard drive seagate barracuda 1.5 tera
8 g ram hyper x BLACK
PSU 550 WATT

i didn't notice that the board is a 1.5 volt but the black ram is 1.65 and the returning policy in Egypt would mean that i would loss a lot of money to replace the ram >> so what do you think i should do

The 1.65 should be fine, no worries
