Motherboard confusion

[AlexRD]

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:

http://support.asus.com/download/download.aspx?model=P6T Deluxe V2&os=8&SLanguage=en-us

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.

 

[stormy13]

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.

You SERIOUSLY need to get a new tech.

Almost sounds like someone from the Geek Squad. :sarc:

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.

So basically, what he told me, is bull**** :X
I kind of thought he was talking about something he didn't understand.

Then, if i buy one of the listed RAMs on that Asus's PDF, it will run the Full Speed?

Like, all those Slots?
Btw: How many slots are there for RAM in the Asus P6T Deluxe v2?
And how the heck did alienware managed to get 24 Gigs of RAM at 1333?

I see your question. No time right now. Will be back. Someone will be able to help you if I do not return soon nenough. I will read your manauls and do the necessary homework before replying.

Six slots on the board,

ASUSTeK Computer Inc.

And how the heck did alienware managed to get 24 Gigs of RAM at 1333?

Easy really. The specs for the ram say it all,

6 x DIMM, Max. 24 GB, DDR3 2000(O.C.)*/1866(O.C.)*/1800(O.C.)*/1600(O.C.)/1333/1066 Non-ECC,Un-buffered Memory
Triple channel memory architecture
Supports Intel® Extreme Memory Profile (XMP)
*Hyper DIMM (DDR3 1800MHz or above) support is subject to the physical characteristics of individual CPUs.
**Refer to ASUSTeK Computer. Or user manual for the Memory QVL (Qualified Vendor Lists.)

Anything over 1333, at least as far as the bios and the memory controller (that's where the first * above comes in) has to be overclocked (increased divider or FSB) to achieve the faster speeds. Alienware didn't do anything other than running the 1333 MHz ram at stock speed.

I presume that what im going to say now is another tech's crap.
He told me that 4 GB's of RAM ( Complete, no 2x) is only for Servers and it is slow. Is that right?

It's sort of true. Not long ago, the only 4GB DDR3 DIMMs available were buffered, intended for servers. I'm not familiar with buffered RAM, but I believe that the buffering must increase its latency. Desktop boards can't use buffered RAM at all, so it's irrelevant.

4GB unbuffered DDR3 is becoming available, but if I check my favorite online source (www.newegg.com), I see only one product:

Newegg.com - Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model KVR1333D3N9/4G - Desktop Memory

($469 for a single DIMM. Free shipping, though.)

Oh, thats too expensive for me.
500 dolars for a single dimm is a ridiculous price

but thx for helping ^^
ill try to rep everyone
btw: this is my 100th post, i should get a cake
