Quick Question on Ram. 1866 & 1600 together?

Inori · Sep 30, 2013

Hi.
I have 2x4gb of 1600mhz in 2 slots and was wondering if i were to put 2x4gb of 1866mhz in the other 2 slots if it would cause some sort of compatibility issue. I'm pretty sure it wont but wanted to make sure before purchasing. The thing is that my 1600mhz ram is oc'd to 1866, don't know if it matters.
Oh and in case you're wondering, the 1866mhz ram is on sale and is cheaper than the 1600 model, so it makes no sense to purchase the model clocked at a lower speed.

It can and is not recommended although it will probably work in around 90% of the cases if the rams are the same voltage.

I'm pretty sure they're the same voltage, since they're the same brand, corsair vengance pro. Geez ram prices have gone up so much.

1866: Click!

I know! You realize as well that if you go to 4 sticks you most likely will have to set command rate to 2T and many boards limit speed as well. I always recommend just upgrading t 2 x 8GB instead and sell of the 2 x 4GB kit. That will ensure that there are no compatibility issue's.

Not a good idea to mix DRAM sets, even of the same exact model, can be problematic, even more so with different brands, different freqs, different CAS.. Best to buy a single set of what you want, that way they are tested to work together, XMP (which is programmed by the set, for the number of sticks) will work, i.e. with two sticks the advanced timings will differ from a 4 stick set, i.e. tRFC for 2 sticks may be 208 and with 4 it may be 314)....also with different freqs in particular it will prob take additional DRAM voltage and MC (memory controller voltage)

okay, thanks. This is for rendering so i was actually looking for a very "well" priced 32gb kit, do you know one?

rolli59 · Sep 30, 2013

It is on back order but the price is right http://us.ncix.com/products/?usaffiliateid=1000031504&sku=77517&vpn=994074&manufacture=Mushkin%20Enhanced
Here other options http://pcpartpicker.com/parts/memory/#z=32768&sort=a8

Thank you.

Tradesman1 :

Thank's a lot. I will just sell my 8gb kit and buy a 16 or 32 kit.

What mobo and CPU? First that comes to mind is the GSkill SNipers, in 1866, $290

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231612

which is $10 less than the same 1600 set

Tradesman1 :

Asus Z87 Pro
i5 4670k

Tradesman1 · Sep 30, 2013

With the 4670K, for 32GB the Snipers are still a great choice, if in the budget, might look at the GSkill Tridents, though they are pricier

Inori · Sep 30, 2013

Tradesman1 :

the budget is limitless, just dont wanna spend 400$ on dominators

Tradesman1 · Sep 30, 2013

(wish my budget was limitless, I went 32GB of 2666 on my 4770K, 2800s and up then were just a bit out of reach

) here's a link to the Trident sets, with the 4670K should be able to go 2400 anyway, if you have a strong 4670K maybe 2666-2800

Tradesman1 :

i can't even imagine the render speeds! aha. I'm running 8gb at 1866mhz

Tradesman1 · Sep 30, 2013

Can also speed things up even more by placing the data in a RAMDisk initially

Inori · Sep 30, 2013

Tradesman1 :

What is ramdisk? Sounds interesting.

Tradesman1 · Sep 30, 2013

You allocate part of your DRAM to be used as a harddrive, DataRam has a free 4GB version you can run and play with, also more info on it here:

Tradesman1 :

Thanks, im gonna try it out

Tradesman1 · Sep 30, 2013

Comes in handy for lots of things and having 32GB or more makes it easy to play with
