A short quick question about RAM>>><<<

[style69]

Hello.

I have 1 gig of OCZ premier series 2x512 DDR400 (pc3200) but i have 512MB of Kingston PC3200 DDR400 in my old computer.

Iw as wondering if i can use the 2x256 sticks in my new computer along with the OCZ ones?

thanks.

Yes, if your motherboard has 4x DIMM's, you can certainly do it. The thing though is due to the Memory Controller being On-Die, all Socket 939 systems w/ 4x DIMM's must run those 4x DIMM's @ DDR333, some people claim to be able to run @ DDR400, but AFAIK, it's unfound speculation. It should run in Dual Channel as well, as long as you put them in the write configuration (1 & 2/3 & 4 or 1 & 3/2 & 4 depending on the motherboard).

when u say "1 & 2/3 & 4 or 1 & 3/2 & 4 depending on the motherboard)"

What do u mean by that?

Some motherboards pair the slots 1-2 and 3-4, and others pair them 1-3 and 2-4.

You can generally tell which slots are paired by the colour (blue and black for example). Otherwise you will need to check the manual.

So, taking the colour example, you want to put the 2 sticks of OCZ memory in the blue slots, and the Kingston sticks in the black slots. They then should run in dual channel mode.

Hello...

I wouldn't recommend using the Kingston modules...

Before u decide to install them try and run some tests in order to see whether u will actualy gain anything from doing so, in bandwidth and in speed...

In most cases 1 GB should be fine...

I also don't have good past experience in mixing different memory modules.

Hope i helped...

Well that setup is out of question since i tried putting in the modules.....followed the black and blue. Result was the blue screen.

So i guess they dont work togather =[

Wouldn't know why... I got a 939 board 4X512 and it IS running at 400...

The Athlon 64 / Opteron CG revision (and later) may be able to run 400 MHz (PC3200 speed) x 4 DIMM slots fine, however it may require 2T CMD RATE though to work, if the DIMMs are more than 1 rank each.

Should be documented here: http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_739_9003,00.html

The early revisions required a reduction to 333 MHz (PC2700), and this was especially true of the early Opterons in particular (they predated the Athlon 64 S939 by a fair margin).

Today most purchased AMD Athlon 64 / Opteron processors should support 4 x 400 MHz. All the the dual-core varients should, as they are E4/E6 revisions. It may require a BIOS update or a more recent board design though, as the reference design may have changed slightly. (Much like the Radeon 1800 to Radeon 1900 reference design changes, Also to clock Graphics RAM at higher speeds).

Here, you see tests of 2 vs. 4 DIMMs of our standard OCZ PC3200 Platinum Rev. 2 based on Samsung TCCD memory chips. In all tests, the timings were 2-2-2-7 and the only difference was the 1T Command Rate with 2 DIMMs and 2T with 4 DIMMs:

I have 3x 512mb 3200 plus a corsair 1gb 3200 and everything works fine

Yes be sure not to put them in the draw or the scribble configurations, because that just causes problems.

Thanks jack for finding my mis-spelling (meant RIGHT) but I guess you're so advanced and 1337 you had to point it out, good job papi!

I am sorry, it was meant as a joke. Should I put that dumb LOL, after all my future jokes?

My experience with OCZ ram with Winbond chips is that you really need to up the voltage (about 2.7) for them to work properly. If you do this, the other RAM will be running at the same voltage. This may void the warranty or cause it to fail due to over-volting.
