Motherboard confusion

I'm sorry i have been asking a lot of questions lately, but i'm buying a new computer and i wanted it to be perfect :X.
So, i heard in Paraguay that Motherboards only support DDR3 1600 MHz speed when only one memory slot is used.
So, if for example, two Memory Sticks are inserted, it would slow down to 1333 MHz.

I wanted to know if thats actually true, or he is just trying to sell me a 1333 promoting that it is a 1600.

The motherboard was : Intel X58SO

(I am on the right section, right?)

Thanks,
Alex.

I don't have the Intel board, but my Asus board uses the X58 chipset.

The manual states "Due to Intel spec definition, X. M. P. and DDR3-1600 are supported for one DIMM per channel only." There are three channels, so three identical DIMMs can be used (in triple channel mode), one *per channel*, with full performance.

However, I have all six DIMM slots filled with 2GB DDR3 1600 RAM. I'm running the RAM at the 1600 MHz frequency.

To get it to run reliably, I had to manually set the RAM voltage (1.65V) and timings in the BIOS setup. The nominal timings are 8-8-8-24, but I backed off to 9-9-9-24. (I could use the 8-8-8-24 timings when I only had 3 of the DIMM slots filled.)

I hope that answers your question.

All things considering, I wouldn't worry about it too much. Unless all you are going to do is run benchmarks all the time, you will be hard pressed to see much if any difference performance-wise between the two.

What memory did you buy?
And i was going to buy a P6T Deluxe v2, will it work with the memory you bought? Or i can use any memory i want?
Does the P6T Deluxe have 6 DIMM Slots too?

Thx

The RAM that I used was:

OCZ Technology | Products | Memory | OCZ DDR3 PC3-12800 Intel® i7 Triple Channel

(I used two of the 3 X 2GB kits.) That it worked for me doesn't prove that it'll work for you, but I'd hope that it would be OK.

I believe that the P6T Deluxe V2 is nearly identical to the original P6T Deluxe (which I have), except that the V2 deletes the Marvell SAS controller. (No great loss.) The BIOS updates for the V2 may be more timely now, though, if the original was discontinued (as it appears).

Maybe your wisest route should be to buy RAM from the QVL (qualified vendors list) for the mainboard:

The RAM I use isn't on the list, but there are some 6GB (3 X 2GB) kits that are spec'd to work with all 6 DMM slots in use.

well said..
real-time testing shows that there is very little noticeable difference
you're actually into the realm of nano-seconds..

Does the RAM adds up?
Example
4x2 GB RAM 1600 MHz = System Recognized - 8GB 6400MHz

thats what my tech said.

You SERIOUSLY need to get a new tech.

That would be like saying that 4 CPU cores at 2 GHz each equals 8 GHz. The 4x2 GHZ equaling 8 GB is correct at least.

Almost sounds like someone from the Geek Squad.

AlexRD - I am not joking.

You really need to find a new local provider of tech support, computer services and supplies.

Run, don't walk.
