I have a FX 8350 in an Asus Crosshair V Formula-Z. Which RAM would be best with that setup. I want 2x8GB Sticks for 16GB. I have three type of ram in mind. If you all could give me some opinions on which would serve me best and why I would appreciate it.

1866MHz 8-9-9-24 1.6V G Skill Trident 2x8GB

2133MHz 9-11-11-31 1.6V G Skill Trident 2x8GB
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

2400MHz 10-12-12-31 1.65V G Skill Trident 2x8GB
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The CPU will be overclocked to around 4.6 - 4.8GHz

I would recommend getting Quad Channel RAM. The CPU doesn't have a Integrated GPU so you don't really need anything faster than 1866 RAM.

I would stay with 2 sticks of 1866 RAM and just get the best timings you can.

If you absolutely need to OC your RAM, go with AMD 2133 performance ram with the FX8350. A lot of good results coming from reviewers testing that combo.


Some considerations before you decide:

Fast RAM will be good for apps, but won't have a big impact on gaming overall. 2 sticks are usually easier to OC and more likely to perform at their highest speeds than 4 sticks. YMMV.

The 1866Mhz at CAS 9 will work perfectly for your needs. Also should double check clearance compatibility with CPU coolers unless you're running a liquid setup. Anything more than 1866 isn't really useful for gaming other than benchmarks. Also AMD doesn't support quad channel RAM, only intel's 2011 socket does, so ignore that completely.

Well, Quad Channel is just Dual Channel 2x so it's supported by almost every new CPU/MoBo.

Nope, the only platform that will run it in quad channel mode is intel's X79/socket 2011 platform. Everything else it will just run in dual channel mode, so there's no point in getting a quad channel kit.

FX 8350 can to 2x dual channel with 4 sticks, not quad channel if I have understood things right. As maddog alluded to, I am sticking with 2 sticks to make it easier on my IMC for more stable OC.

Seems like 1866MHz RAM with low timings is the way to go for ease of use and stability.

Say I get 2133 or 2400. Other than telling my Mobo what frequency to run at would I need to up the CPU/NB voltage or HT/NB speed to make it stable?

Using H100 for cooling so no clearance issues.

The only thing you would have to do is manually set the voltage and timings if they don't auto detect. If your CPU is overclocked you shouldn't need to increase your NB or HT voltage, however I would suggest increasing their frequencies. ~2500 is the sweet spot for the 8350 that most people have found. I am currently running mine at 2600 both HT and NB.

Unless you want to throw out the G34 and C32 sockets from AMD, though those require Opterons...16 cores @ 3.2 GHz anyone?

Realistically though, *not* great for gaming. It could be done, but the FX series would be much better.

Does anybody know what the max safe voltage is for these modules?

Do not exceed 1.5V

They come 1.6v - 1.65v stock..... I was thinking with a well cooled case 1.75v- 1.8v would be ok.

For RAM or your CPU? AMD CPUs come stock @ 1.35V and most RAM is 1.5V. You can run RAM @ 1.65 V and AMD CPUs should not exceed 1.5V unless you really want to shorten the life span.

I guess I should have made it more clear. I listed three different kinds of RAM on my OP. They are ranging 1.6v to 1.65v stock. I was wondering what the max voltage for the RAM is for OC purposes.

1.65V is usually sufficient for OC purposes...you could go a little more, though I would try it at 1.65V first
