How to connect dual channel ram on a msi 865pe neo-2 plat.edition ?

hi....
can any one tell me how to connect the RAM as dual channel on the MSI 865PE Neo-2 p Platinum Edition ?
i did like what is written in the manual but nothing happened it only works as a single channel....
the RAm is 2x512 spectek DDR400 PC3200....
pls help me.............

Franknputer is right.
All systems that I build for my gamers runs in Dual Channel and the combo is 1 + 3 or 2 + 4 or 1 + 2 + 3 + 4. 1 x RAM in Channel A and 1 x RAM in Channel B minimum will give your Dual Channel Linear Mode message during startup and you know that you are running Dual Channel.
Next, it is always recommended to have the same make and model and capacity of the RAMs if you want to run in Dual Channel.

Dual Channel Ram in w510

I've got a w510. On Lenovo's site it says that it's capable of dual channel. i've got 2x2GB right now in my system at 1066. i ordered 2x4GB at 1066. my question is
will i still be able to run dual channel?
and if so, how do i arrange the ram being that two slots are in the back and the other two are on the other side underneath the keyboard.

Ram came in this morning. got lucky on the first try with getting it to run dual channel.
when i opened the ram slots on the back of the pc i placed a a 4gb stick on the left side.
then i lifted the keyboard for the other ram slots and they're placed on top of each other. i took the one on top out and placed a 4gb stick in there. then i placed that 2gb stick that was there and placed it in the only slot remaining. booted my pc and on the start up it said it was installing some stuff and something about dual. and then to make sure i checked cpu-z and it showed i was running dual.
this helped a bit on how to install the ram

went from a 5.9 to 7.2 on the windows index score. now my lowest is the harddrive which is at a 5.9. probably going to wait until SSD becomes a lot cheaper to get one.

K8T Neo2-F MS-6702E Error using Dual Channel RAM slots

Hello
with RAM banks on slot 1 & 3 or 2&4 as recomanded, the PC doesn't start up
on the D-Bracket 3 red leds signs memory error!
The Ram is Kingston kit 2x512 KVR400x64C3AK2/1G
Someone can help me?

I thought you may be interested to know of my experience with memory on this motherboard. I had 2 x 256MB of Geil Value PC3200 DDR Ram on slots 1 and 3 for months and months with no problem at all - they were identical modules but NOT a matched pair - and ran in dual channel mode @ 2.5 3 3 6 and 400MHz according to CPU-Z ... absolutely no problems at all. These are double sided memory modules.
I wanted to upgrade and bought a matched pair of 2 x 512 Geil Value PC3200 DDR RAM intending to upgrade to 1.5GB ... I thought that I should put the two 512s in the green (DIMMS 1 and 2) and the two 256s in the purple (DIMMS 3 and 4) ... all I got was 3 beeps ...3 beeps, etc ...so I put the two 512s in DIMM 1 and 3 .... no problems!!!!! ... then I emailed MSI and got a reply ..... put the two 512s in slots 1 and 3 and the two 256s in slots 2 and 4 ... works fine!! ... now I have 1.5GB memory.
One other thing - the memory now (exactly as the manual says it would!!) runs at 333 on 2 3 3 5; this is 2 clock cycles for the CAS latency (???) ... instead of 2.5 .. so although the bus speed is slower, it takes fewer clock cycles for this to happen (whatever it actually does - something to do with the Column Address Strobe - how quickly/regularly the columns in memory are strobed. ...).
I don't pretend to be an expert but 2.5 clock cycles at 400MHz is equivalent to 2.5 nanoseconds per cycle which is 6.25 nanoseconds for 2.5 clock cycles .... 2 clock cycles at 333 MHz is 3 nanoseconds per clock cycle ( at first glance slower ... but) so 2 clock cycles take 6 nanoseconds ... so this has to mean that 2 3 3 5 at 333 MHz is faster than 2.5 3 3 6 at 400 MHz doesn't it?

How to Enable Dual Channel?

Hi,
I have an MSI K8N Neo Plat, with a Newcastle 3200+ cpu, and two sticks of Kingstone DDR-SDRAM PC3500 - 256Mb.
Anyway, according to CPU-Z the memory is running in single channel mode...
Is there any way to get it to run dual channel?
I've tried it in slots 1&2, 1&3 and 2&3, but all report single channel.
The CPU and board are not overclocked in any way, and it is running stable and has no other issues (aside from the incorrectly reported CPU temperature).
Thanks for you help...

Ok, I'm probably just getting DDR and Dual Channel mixed up
So, on bootup it reports...
DDR400 Memory Clock : 200Mhz
TCL:2 Trcd:3 Tras:8 Trp:3 (1T Timing)
Which is what should be expected for this kind of ram on this board?
(I know 1T and TCL:2 are both good values, I presume the DDR memory clock at 200 gives a 400Mhz throughput?)
Also If I were to add a 512Mb stick into this would it still run at DDR400?
Thanks....

Gaming 3 motherboard not working with dual channel ram

Hello,
Whenever I try to put the RAM in dual channel (slots 1/3 or 2/4) in the motherboard Gaming 3 (z97), the motherboard stops working, and starts a loop of getting power for two seconds, and turning off again.. untill I kill the mains.
This doesn't happen when the Ram is in single channel (slots 1 and 2)
The ram is Corsair Value select 4 GB x2
My specs are:
Intel i5-4690k
Nvidia Gtx 750 Ti
MSI Gaming 3 motherboard
Corsair Value select 4 GB x 2
Samsung Evo 128 GB SSD
The bios version is 2.3
Any help would be great. Is it a motherboard specific problem? Or voltage issues?

Hi,
can you refer to manual and check which DIMM slots are default? As far as I know, they're 1 and 3.
Test each RAM stick individually, by going from DIMM #1 until #4. Working fine? Test the other same way. Also look around CPU socket and RAM slots for any scratches or other unusual stand offs. Also try to lower RAM down to 1333 and try again.

Z97 Gaming 5, Dual Channel RAM not working?

Here are my specs for the moment , Windows 7, Intel Core i7 4770k, 8,00GB Single-Channel DDR3 @ 666MHz (9-9-9-24), Nvidia GeForce GTX 780 (EVGA)
As the title says dual RAM is not working, when I put all 4 RAM sticks in their slots or even just two in dual channel mode my monitor will not respond and the screen is just black, can't even go to BIOs.
The BIOs settings are at 1333 MHz and 1.5 v, I've tried raising the volt and lowering it, anyone have any ideas?
I've tried the 1-3 and 2-4 slots with two 4gb sticks and it does not work, but the 1-2 and 2-4 works fine, have also tried all the individual sticks so none of them are faulty.

Please clarify. You mean a single stick works in 2 or 4 but not 2 and 4 together? So that means DIMM slot #3 is the only one that doesn't work at all? My suspicion is a grounding or short under the mainboard by an errant standoff, or the DIMM slot has some debris in it, or the slot is just plain faulty. Other possible is a pin problem in the CPU socket.

K8N Diamond SLI with FX-55 (San Diego) and 2 sets dual-channel RAM @ 400MHz ?

I currently run this with Patriot 2048MB DDR PC3200 DUAL KIT 1024MB x 2, 400Mhz, CL2-3-2-5 (PDC2G3200LLK). I plan to buy another kit like this and would like to run the system with 4GB at the same RAM-speed as with 2GB. Is this possible?

ap1978,
It comes down to how well the Memory Controller on your CPU can handle 4 sticks of RAM.
Btw, could you tell us what you will be running that needs 4Gb of RAM?
Take Care,
Richard

How to connect dual monitors

Hi, I am not very computer literate, so I apologize in advance. For my job, I need to connect another monitor to my HP Touchsmart Desktop all in one model 310-1000, but do not know how or if it is possible. Can you please tell me step by step what I need to know/do in order to connect another monitor? Thank you in advance!

Thank you for the additional information. I changed the link in my first post to show examples of USB 2.0 to DVI adapters. You will have to make certain that you buy the correct one. It has to match the connector on the monitor. I suggest that you contact StarTech Customer Service for help with choosing one that matches your monitor. You don't want to have to pay for return shipping if it is incorrect. StarTech has good products. Please click the "Thumbs up + button" if I have helped you and click "Accept as Solution" if your problem is solved.

Need Help with deciding 2x512 mb dual channel ram for k8n neo4/sli plat

Ok well i was hoping someone here could help me out, I want to get 2 sticks of 512 of ddr 400 ram for under 150 dollars i was thinking corsair xms or Ocz
these are the 2 links i was looking at
http://www.newegg.com/Product/Product.asp?Item=N82E16820146883 (tighter timings)
http://www.newegg.com/Product/Product.asp?Item=N82E16820145466 ( i like the lights lol )
If you could please comment on these 2 products, or if you have better choices please tell me
Andrew

Damn! Those are some great prices!
If I had only those two to choose from I'd go with the OCZ.
Myself, I'm a Mushkin fan, it's a little more $$ but at those prices, I may even pick up some more for my new build. I've paid over 200 for mine each time, so 166 is a great price.

How do I unlock the AGP/PCI for MSI 865P Neo?

I tried to overclock my P4 2.8GHz by changing the FSB. I noticed that the frequency for AGP/PCI and memory will change together with the FSB. I am unable to just change the FSB only. How do I unlock the AGP/PCI frequency so that only the FSB is changed? If not, i can't do overclocking.

Hi msklee,
I dun think that we can unlock that in the features as it is BIOS controlled... If you find that after you o/c and things are too tight and system will not boot up, juz lower your o/c specs and it should do well.
By the way, I hope that you do not spam the forums with the same thread repeatingly juz to ask something similiar , so I will close the rest of the similiar post to ensure pple dun answer here and there, and you dun have to go so many threads to get solns too... In the future 1 thread will do all .
All the Best... :D!!!

Random Reboots with dual channel

Hi,
I just bought yesterday the following system.
Intel P4 2.8 Northwood HP enabled
MSI 865PE/Neo 2 Platinum Edition
Maxtor Diamond Star 9 200 GB 8MB Cache 7200rpm
Elixir 2x512MB DDR 400 CL3
Toshiba DVD 16x
Creative Geforce 4 Ti 4400 128MB
Logitech Cordless Keyboard connected and a logitech cordless optical mouse
19 inch belinea monitor.
The power supply is a no name product LPK2-30 with the following specs.
420W
3.3V 28A
+5V 36A
-5V 0.5A
+12V 17A
-12V -0.8A
It says that is P4 ready, i know which does mean nothing
Operating System:
Windows XP Professional SP1
All Hotfixes and Updates applied
Newest drivers for all the system parts
The errors during the windows crashes are irq not less or equal or page fault, which looks for me pretty much like a problem with the memory.
Ok what i tried so far.
Single channel with 512MB works fine.
Single channel with 1GB works fine except one strange thing restarting the machine and it got stuck during the bios loading worked fine after i pressed reset.
Dual channel 1/3 1 GB get random reboots.
Dual channel 2/4 1 GB even worse but i think at this point my newly installed died.
I tried to set memory voltage from 2.65 up to 2.8 but did not change the behaviour.
memtest with one modules in slot 1 no errors
memtest with dual channel 1/3 1 gb no errors running 30 minutes
i will try now a memtest with the second single module in memslot 3.
No MAT or dot ram settings are 3,3,3.
I am bit running out of ideasö
before i forget i updated the bios from 3.3 to 3.5 but did not change the problems.
Maybe you guys have some ideas what else can i try.
thx a lot in advance. i hope i provided all informations which are necessary.
greetings faxe

Hi,
i tried a few more things which make confident that i have the problem narrowed down to the memory.
i tried to install windows again with only using the third memory slot single channel and it worked fine.
now i tried to go down with the memory speed to ddr333 and using dual channel and so far that seems to work too.
so i think i will go for other memory.
if you think i am wrong please correct me
greetings markus

W530 dual channel

I upgraded RAM on my W530 and it's working only in single channel mode. How to enable dual channel in BIOS?
Here is screenshot about my RAM
http://imgur.com/ilbCUil
Solved!
Go to Solution.

I did some testing earlier this year and did a short write-up and decided that the advantages of dual-channel, frequency and cas latency were more theoretical than practical. I was using a laptop with 2 slots, so it isn't quite the same, but it was an i7 Ivy Bridge CPU, so there should be more similarities than differences. This is what I wrote:
Probably more often than once a week, I see or hear a question regarding advantages of buying faster memory or using matched pairs of DIMMs. Obviously, using memory that is rated faster than the bus speed yields no improvement, and I always believed that advantages of "matched pairs" was more theoretical than actual. For no good reason, I decided to run a semi-scientific test. I have a T430s machine here, which will run at DDR3-1600 or DDR3-1333 mHz, depending on the memory installed. I also have 2 matched pairs of 8GB DIMMs. One pair is Corsair Value memory (DDR3-1333 CL-9) and the other pair is Corsair Vengeance, their "better" memory (DDR3-1600 CL-10). My idea was to test the memory 3 ways: 2 faster DIMMs, 2 slower DIMMs and mixing one of each type. My expectation was that the fast memory would run at 1600 bus dual-channel; the slow memory would run at 1333 bus speed dual-channel, and the mixed configuration would run at 1333 bus speed, but not use dual channel operation and be the slowest. First, I ran the windows7 "windows experience test". The faster memory gave a "memory operations per second" score of 7.6, while the slower memory gave a score of 7.5. The mixed option was the same as the slower memory.
I then ran Memtest86+. (the free memory tester I use) First, it became obvious why the mixed set ran as fast as the matched pair of slower memory. The mixed set was using dual-channel operation. I now assume that "matched pair" really means any 2 of the same size. When I ran the full memory test, the faster memory took 1:20:45. The slower memory took 1:21:55. I ran one more test to look at single-channel vs dual-channel operation. I ran just one of the faster DIMMs. If it were running at the same speed, the test would have taken half the time taken by the pair, or 40:23. It actually took 41:52, and the windows experience score fell from 7.6 to 7.2. I was going to complete the test by running 2 4GB DIMMs, but the only PC3-1600 4GB DIMMs I had were the ones that Lenovo includes with systems, and it is slightly slower that the DDR3-1600 memory I used (CL-11 VS. CL10).
It seems clear to me that one would never be able to notice any difference in any real application, but there was a measurable difference that would allow someone to win a "mine is bigger than yours" contest
