1.65v RAM dangerous for 3770K?

Hardware Other Hardware
#1

I've been looking into buying some new RAM, and this is what I found:

http://tweakers.net/pricewatch/282503/mushkin-redline-8gb-(2x4gb)-ddr3-pc3-17000-cl9/specificaties/ (be warned, it's in Dutch)

It's some Mushkin Redline 2133 MHz. 2x4GB DDR3 with a CAS latency of 9. It's not that expensive, so I really want it for my rig. (3770K, GA-Z77X-D3H(Rest on profile)). Only thing is, the voltage is 1.65v, but Intel says you shouldn't go above 1.5v (1.575v really).

Should I do it, is it safe?

1.65v ram on 1.5v channels will work. Just do some though testing, if its a little flaky - drop the volts in the bios to 1.5 ~ will most likely have to drop the frequency down a little as well.

Id be looking at this kit > https://tweakers.net/pricewatch/317410/kingston-hyperx-khx16c9k2-16x/specificaties/

or this https://tweakers.net/pricewatch/312932/patriot-viper-3-pv316g213c1k.html

You'll have more luck running 2 sticks at a high frequency along with a cpu overclock then that of having 4 at high frequency plus the oc.

BTW there is not much to be gained by using high speed ram on a z77 platform.

2133 MHz isn't exactly "High speed" seeing as how its the maximum specified JEDEC standard for DDR3. Anything over 2133 MHz I would consider "High speed" as it is overclocked RAM DIMMs. 2133 MHz ram at 1.65v indicates that it's using 1600 MHz chips in it overclocked to 2133 MHz

My advice is to seek 1.5v 2133 MHz RAM if that is what you want to run on Intel.

1.65V is perfectly safe.

Source: I have run 1.75V on Ivy before.

I've found something: http://tweakers.net/pricewatch/310278/geil-black-dragon-gb38gb2133c10adc.html (again, be warned, it's in Dutch)

What do you think? Should I get it or not?

GeIL is a reputable company and ASUS lists quite a few of their RAM on their QVLs for various motherboards. I would buy it, it's priced pretty reasonable at ~$100. I did the conversion to make sure the price was reasonable compared to USD.

#7

Thanks man, I will. I love that you actually gave me a definitive answer ;)

#8

Just noticed that in my post, I said that it was a kit of 4x4GB, when it really is a kit of 2x4GB. My apologies!

#9

That doesn't impact any of the answers previously given.

Cheers :)

 

#10

I know, but I thought I'd just point it out.

Last question: I've found something even better! (I think ;)) 

http://tweakers.net/pricewatch/346836/corsair-vengeance-pro-cmy8gx3m2b2133c9.html

Corsair Vengeance Pro 2133 MHz. CL9. (lower CAS, way better looking, a bit more expensive (€8))
What do you think?

If it's a yes, I'll buy it.
