Wrong RAM MhzÑ Bought 4Gb 1600Mhz, Want 8Gb ¿x? Mhz - (DH67BL)

Hi: I recently replaced a very slow laptop with a far superior desktop to edit videos and general use. Eg. Even by not "maximizing" I feel like a rocket. I live in Peru, and this weekend a friend will bring me an additional 4GB RAM (and maybe a video card.... but I dont know).

I need to know if I should "halfway correct" my RAM mistake or "100% repeat my RAM mistake"

I recently purchased, and am now using:

MBO: Intel MB DH67BL
Chip: I7 2600 (3.4 Ghz, LGA 1155, 95w)
Video Card: Presently None, And have no $75 +/- ideas.
RAM: 4GB (1 piece) Kingston Hyper X 4GB 1600MHz DDR3 Non-ECC CL9 DIMM (KHX1600C9D3/4G)

- According to Intel literature, the DH67BL has a max ram speed of 1333Mhz. By error, my current (and non-returnable) RAM is 1600mhz.
- According to my former understanding of RAM, one always wants (wanted/needed?) to remain "parallel" in brand, size, speed and number of modules etc.

In light of my error, I would be grateful for any reccomendations (and adore any explanations!)

a) Should I buy and additional IDENTICAL 4Gb. RAM stick, or
b) Should I buy a 1333Mhz 4gb Ram Stick (presumably from same maker etc.).
c) Any $75 video card comments?

NOTE: Throwing original 4GB away is not a $$ option for me. Greetings from the DEEEP south, and thank you very much.

The speed is not a problem.

But the voltage is. U need 1.5V and u have 1.65V and that voids the CPU warranty.

Make sure they have the XMP profile! So u can select the 1600MHz speed : )

My favorite is ->> I recommend CORSAIR Vengeance 99% of the time, quality RAM and low profile with XMP profile. And if u will get an aftermarket CPU cooler, low profile is the worry free remedy with perfect fit with any large cooler.
CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
Vengeance Low Profile heat spreaders have a reduced height of 1.03" (26.25mm). They're designed for high-performance systems with extra-large CPU coolers, small form factor system builds, or any other space-constrained application where standard Vengeance memory might not fit.

You could lower the voltage to 1.5v. It might not run at 1600MHz if you do and you could then need to reduce the effective frequency down to 1333MHz, but no serious harm done there if it's what you need to do. Running the memory at 1.65v can reduce the lifetime of the CPU (that's why it voids the warranty), so you should lower it, or if you need help, maybe your friend can help with that.

1600mhz ram is perfectly fine, it was just overclocked from the factory. As long as your ram is 1.5v it should be fine, also get a dual channel memory kit, it will run better than a single stick of ram.

The problem is that it's not 1.5v RAM. It's 1.65v RAM. He's getting a second module for dual channel from a friend.

The voltage should be lowered from 1.65v to 1.5v and if necessary to keep the machine stable, reduce the effective memory frequency from 1600MHz to 1333MHz (the RAM might not be able to run at a higher frequency such as 1600MHz after the voltage is lowered).

If you can get the voltage down to 1.55v or so (1.5v isn't the maximum, 1.55v should be fine too), then it should be safe. Otherwise, it probably won't last long because the CPU will probably damage itself because it can't handle the RAM at 1.65v.

Technically there is some other setting that can be raised (needs to be raised from 1v or something like that to about 1.15v or 1.2v) that will allow 1.65v RAM to run fine, but that would void the warranty and I don't remember the setting's name.

Wow! I am reluctant to write anything for fear of interrupting so many helpful and well intentioned comments! Thank you T.H. Community so much. ANyway, I will write:

A) Yes, it is in fact 1.65v. I had no idea of this, and would have never known until (maybe) the post mortem of my CPU, so my goodness THANK YOU ALL!! I bought such a powerful machine (for my level) since I don't have the money to replace it..ever! Therefore I put in fans, bought a very ventilated and large case and bought a 630w (real) power supply (and sacrificed a video card $$) all in an effort to NEVER let it heat up, or ask the machine for too much.

B) Therefore, since only your great grandmother is LESS tecnical than I am, I think I ought to sacrifice this fancy pants RAM and forgo a video card again to buy 2 DIMM of 4MB good quality, factory approved 1333 Mhz - 1.5v RAM. since BIOS and all of those words spells DISASTER around me, as I have no idea how to "over-under clock" things that smart engineers designed. Remember, I'm the guy who bought 1.65v without even knowing it!

C) Is my childhood memory of "always buy identical RAM in Pairs" still true? Eg. should I permanently top out at 8GB (4x2), since I will never buy/need 16 GB, making 12 GB (3x4 an "odd number" Perhaps even 8 is more than enough (my max & typical uses is some 20-24 www pages open at a time, while working on a big Powerpoint or someday Adobe Premier). My newest game is Age of Empires from 2006!!!

D) Depending on the RAM decision, does a $50-$75 video card exist that is worth my money and would "add" to the I7 HD grafics 2000 onboard rather than "canceling" it?

Again, thank you and I wont be offended when you tell me to "buzz off" as I have to think these questions are pretty boring for you guys, you have already helped a LOT ion teh 1.65v / 1.5v issue!

B) get 1600MHz, but still make sure that it is 1.5v, if you can't change the settings of your current RAM.

C) Get a single kit that has two 4GB modules for a total of 8GB. Identical pairs are still the best possible way to go and getting a kit that has two modules that come in a pair is the absolute closest to a gaurantee that they will work together as you can possibly get.

D) No graphics card can work with the HD graphics. If you get a discrete card, then the HD graphics will not do anything except for work such as QuickSync. The HD graphics can not work in tandem with other GPUs like AMD's Crossfire or Nvidia's SLI.

Don't worry about us leaving just because your first issue has been more or less explained to you. We're here to help you and I can at least speak for myself when I say that that is what I intend to do, to the best of my ability.
