Dual channel slots

Just want to make sure i got this together right, normally this is a no brainer but for some reason im left wanting a verification. Probably because some of my older gear all used to skip a bank for dual channel.
MSI785gm-e65 , i populate dimm1 and dimm2 with my matched set, runs unganged but is dual channel?
Thanks in advance.

It is dual channel indeed. You have to match the slots of the same color. I think you have used the black ones and the memory then should be running in dual channel.

770-C45 Dual channel slots?

OK, I read the manual and it doesn't make it very clear, do I put the 2 dimms in slots one and two, or one and three for dual channel? Or in other words should I put the dimms in the same colour slots? Thanks

I think the problem is MSI can't decide how to show things.
Either they can
- let the colours of the slots show (memory bus to the processor) channels
or
- have the colours show how to enable Dual Channel.
Until MSI has decided that, they can not make a good manual.
Another option is to have one and the same colour for all slots, and have a nice description in the manual*) and some guidance on the motherboard how to enable Dual Channel.
*) Have a strong feeling MSI does not like to write too much new in each manual... Copy and paste from the last one saves their linguistic skills for another day.

K9N PLATINUM(NON SLI) DUAL CHANNEL MODE PROBLEM

hi
put a new system together with the following specs:
amd am2 3800+(2ghz)
k9n platinum 1.20 bios
2x512 kingston ddr2(667mhz)
pci video(yes not pci-e)have not decided which vid card to get yet.
500w psu 12v 35a,5v 25a,3.3v 25a
liteon dvd burner
seagate 300gb ide 7200/16 meg cache windows xp-pro sp2 with all updates.
not overclocking or even trying to.
no sata drives connected.
has never failed to post,boot windows and no lockups or blue screens.
ok,i am trying to get the memory to work in dual mode.
everytime i put the memory in the dual mode slots,the cpu clocks down to 1ghz instead of 2ghz.
verified by bios,windows and cpu-id
i have tried different memory(both ddr2 533 and 667)667 installed now.
also never had any install problems with windows and everything runs fine until i tried dual mode.
after the cpu clocks down to 1ghz,the only way to get it back to normal is a bios reset( load defaults
or press red button).
if i leave the memory as single channel then i have no issues.
also cpu-id says the chipset for my board is nforce 550,i thought k9n platinum had 570 nforce chipset?
this might just be a problem with cpu-id though.
any thoughts on the cpu down clock problem in dual channel mode?
thanks,jeff

1 assume you can get into BIOS with 1 stick only?
Go into the BIOS and manually set the timings and voltage to what your memory manufacturer recommends. Use a 2T command rate and see if it works.
Try both "sets" of dual channel slots, i.e. the two left slots or the two right slots.

Trouble with Neo4 Platnum and AMD X2 with dual channel memory

I just installed an X2 3800+ in my Neo4 Platnum board. The board had a 3500 in it and ran fine. When I installed the X2, the machine will no longer POST if the memory is in the dual channel mode. I flashed to the latest BIOS (1.8) and it still does not work. I am using 2 Corsair XMS 2-2-2-5 Dimms each at 512MB. The PC POSTs fine if I place both modules in the Green slots. It does not work with 1 in green and 1 in purple (with either Dimms1-2 or 3-4). Has anyone else seen this?

Todd,
Your last post help me understand your situation a bit better. Here are some questions for you:
1- On your old system did these memory sticks work fine has a dual channel pair? Were these 2 memory sticks bought has a dual channel rated matched pair?
2- In your own words give me your definition of POST?
3- In your own words give me your exact detailed rendition of what happens when you try to post with dual setup. (How far do you get? Where does it hang up?)
4- Can you access your BIOS if booting with only one memory stick? If so, this is only for testing purposes, set your memory as 2.5,3,3,8, and 2T and add 0.05 volts to both your CPU and memory recommended voltages. Save, exit, and then shut down your system. Re-install the second stick of RAM in a proper dual channel slot. Re-boot and see what happens. If successful posting and booting in dual channel with this BIOS config go back to your BIOS and tighten your board and memory timings one at a time until you ID the perfect BIOS config for your CPU and RAM. Do the same with your CPU & RAM voltages.
AMD CPUs encompass their own memory control devices. There might just be enough variance between your older & newer AMD chips to reject dual configuration. If this is the case you may be able to correct it by using step for above. If this does not work, you sould borrow some suitable and proven dual channel memory sticks from a friend to see if the will work in your rig as dual channel?
Just keep on trucking & you'll solve it

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.

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?

Dual channel with 4 slots on MSI Neo4 Platinum

I read from the booklet that the dual channel on the MSI neo4 platinum will only run at 333mhz when using the 4 slots with dual sided chips on the Dimms.
Anyone knows if there's a way to run them dual channel at 400mhz.
Here's the setup:

Yes, you get better performance with 1T compared with 2T - check with Sandra mem.benchmark.
A note for the above: that is for the same timing modules. But
2-2-2-x 2T would be faster then 3-3-3-x 1T,this is important to realize when considering 2GB.
4x512 2-2-2-x at 2T would be faster or as fast as 2x1GB 3-3-3-x at 1T and alot of the 1GB modules out there don't have fast timings.

MSI K7N2 Delta ILSR and Dual Channel

I just got an AMD Athlon XP 3200+ processor and 2 matched sticks of Mushkin 2-2-2-6 512meg pc3200 ddr. The computer works fine when the memory is in normal mode. But when you want dual channel, everything goes haywire. The computer reboots over and over. I have tried changing the voltage, and changing the memory timings, but nothing seems to work. Does this mobo hate Mushkin memory? I have heard of other people running dual channel memory on this board with no problems, but I have a bucketful. This board only has voltage settings for memory in the bios of 1.5, 1.6, and 1.7. This memory chooses 1.7 when I put it in auto mode. Could it be the modules are not getting enough juice? Any ideas?

Last night I was trying to find some kind of a solution to the America's Army critical error problem(yeah, got that too). I went to disable fast writes within the Smart Gart utility, and when I went for a reboot, my computer went into a reboot loop very similar to the one I got when I first tried to run these 2 sticks of memory in dual channel. It took a while to get the computer to stop it. At this point, I starting believing my problem was not a hardware problem. When I finally got the computer to boot into xp and stay fairly stable, I first ran checkdisk and had it repair any damage. I updated my video drivers from 4.7 cats to 4.8. I updated my bios, as a new revision just came out not too long ago. I reinstalled directx 9.0b. I reinstalled my chipset drivers as a precautionary measure. I then checked both memory controllers using one stick at a time, and both memory controllers checked out. Yes, I am using 2 sticks of 512 meg memory each. I then put one stick in slot one and the other in slot 3 to try for dual channel again. The computer booted up normally, did not reboot, and ran stable. I then ran 3DMARK 2003 and 2001SE, and posted new high scores in both. I am not sure exactly which action I performed was the one that fixed the problem, but the shotgun blast worked. I appreciate all the help everyone gave me.

[Other 865 Series] MSI 865PE Neo2-V and Dual Channel Mode Question

Hello, I have a quick question regarding dual channel mode with my current motherboard. I have an MSI 865PE Neo2-V and am wondering if it is possible to enable dual channel mode while having three RAM modules inserted in the motherboard.
For example, I currently have one 512MB PC3200 module in my computer. If I purchase another 512MB module and run them in dual channel mode, will it be possible to buy a 1GB module or another size module, and still have all three slots run in dual channel mode? Or is dual channel only operational on this motherboard if only two of the three slots are occupied?
Thanks.

Dual channel requires an even number of sticks.

MSI BIG BANG TRINERGY dual channel problem!

Hey forum, I just installed a newly bought msi big bang trinergy. Everything went according to plan except from the point where I installed the 4gb (2x2gb) ram dimms( I have the XMS3, 4gb kit by Corsair).
Let it be noted that i followed the instruction manual and installed the dimms in the proper slots. Then when the moment of truth came and powered up my pc, it wouldnt boot. It would go into an endless restart cycle without booting. Then i unplugged the dimm3 and started only using dimm1 and everything went well. I also switched the ram dimms (in case one of them was faulty) and placed it in dimm1 and again there was no problem.
My take on this situation is that there must be some hardware problem concerning DIMM3. I also run a BIOS update in hopes that something might change but no luck.
..So what is your take on this?
Thank you in advance for the advice.
P.S Since i had a P55 mobo before Big bang i read that format is not necessary so i didnt format the pc. Can that be the cause of the dual channel mal-function?

Quote from: Jack on 11-May-11, 22:57:43
Nope.
There are a couple of explanations for the behaviour:
1) there is a problem with the modules
2) the memory slot itself or underlying circuits is/are defective
3) there is a short circuit problem somewhere inside the case which basically blocks that particular memory slot
4) the CPU (or its memory controller) is defective
5) there is some sort of pin-contact problem [bad contacts between the board's socket pins and the contact pads of the processor], caused by bent or broken pins or by too much pressure exerted by the CPU's heatsink
I would start poking at explanation 3) by testing the board outside the case on a non-conducting surface in barebone configuration and, in case that does not change anything, go for number 5): take off the heatsink and inspect both socket pins and contact pads for any irregularities [use a magnifying glass!]
I went to a technician to check the mobo where we tried different memory modules and cpu (100% working ) on a bench table.The pins on the mobo were not bent or anything. We checked all the points you mentioned that needed to be checked but still the problem persisted so it was a memory slot problem. Thanks for all the help! Really appreciate it, the replaced mobo works perfectly

Dual channel memory mixing on a K8T Neo2

Hey all,
I have a K8T Neo2, Winchester core 3000+ and had it running with 2 TwinMOS 512 MB-DDR400 sticks in dual-channel mode. Recently I decided to add RAM, but to invest in a more solid brand. So I bought a Corsair TWINX1024-3200C2 set and plugged it in. AFAIK the right combination in the board would be the have one set in slots 1 & 3 and the other set in 2 & 4. So far the board will only post with the Corsairs in 1 & 3 (and not with the Twinnies there). But if it posts, the clock is set to 333 MHz (which is an issue of the Winchester core I understood), but more importantly the system becomes unstable: reboots etc. Even stranger is the fact that sometimes after POST I get 8 beeps from the BIOS, which suggests that the Video RAM or framebuffer is defective. Is this somehow related to the RAM I installed? Is the framebuffer mapped to the RAM at bootup for example?
I did try to change the command rate to 2T, didn't seem to help. Bios version is 3.3 by the way. Thanks for any help.
Oh maybe the vid card specs are also relevant: Sapphire Radeon 9800 pro with 128mb. Power supply is Tagan 580W so unlikely to be the problem

Quote from: Tiresmoke on 03-November-05, 23:54:30
Have you tested each stick of RAM with Memtest86 yet? You may have a bad stick. You also may want to try the new set in a different socket sety. Another words if it was in 2/4 then try it in 1/3. If the timings are different on the two sets try setting to the slowest settings of the two. You may have to exchange the set for the twin to the old set just to make it work as mixing RAM rarely works well.
Good idea on the memtesting, I'll do that tonight. I was afraid that the mixing wouldn't work well, but I thought at least if for each channel I used the same pair it wouldn't matter. Practice might indeed prove that as being a wrong assumption

• Supports four unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333/1600 DRAM, 8GB Max
• Supports two unbuffered DIMM of 1.8 Volt DDR2 667/800 DRAM, 4GB Max
With the last BIOS, it states that 4GB modules may be possible, but looking at the memory test report http://www.msi.com/file/test_report/TR10_1393.pdf it seems this was only done for DDR2 modules, as these are the only ones reflecting this.
Suggest you check with MSI technical if the BIOS should accommodate DDR3 4GB modules as well. >>How to contact MSI.<<
Do a CMOS clear, then once in the BIOS, set your DRAM ratio so that the DRAM is at 1066. See if that works.

P7N SLI Platinum Unstable with over 2GB ram and/or dual channel memory on.

Hello need some help or to report something to MSI regarding blue screens, freezes when booting Vista 64 (SP1 + all fixes installed) with more then 2GB ram. Single channel mode works (either 1 stick of 2 GB or 3 sticks of 2GB) and is rock stable. Booting with 2 x 2 or 4 x 2 yields instability and blue screens.
I read over Microsoft's hotfix KB929777 however it appears this patch was applied during SP1. http://support.microsoft.com/kb/929777 - when I attempted to apply this hotfix I got the message this update does not apply to your system.
Memory tested in other gaming system using 4 sticks of G.Skill 1066 DDR2 ram and still have the same issues. Other forums like Evga.com, Tom's hardware and 411overkill.com tend to suggest some problem with this new bios version 2.0, written by Nvidia. Some others mention possibly an Nvidia nforce driver issue.
Therefore, under duress during testing - with 1 stick or 3 sticks of ram, all tests perfect and passes all stability tests, good marks in Sandra, plays any game. With 2 or 4 sticks of ram, very unstable won't stay up but for seconds.
Any ideas? (Tested 7 ways until Sunday!)
My other rig, rocks solid and stable with Vista 64.... It's the Evga new mainboard 780i with triple SLI (132-CK-NF78-A1), 8gb of Gskill 1066ddr2, MSI 8800GT (x2 sli mode) Q6600 @ 3.2 ghz - Raid 0 on dual WD caviar 640 gb/sata 3.0gb/sec. Seasonic 700w p/s. 8gb of memory and not a hiccup. Ram 2.0 volts, cpu @ 1.36v. Will handle the memory from both systems with out fault.
Considering I can swap memory back and forth and confirm it's not the sticks, swap graphics boards (own 3 of them!) and rule out that....
Fyi. Any help is appreciated!

Dump question, but have you pickup the correct update e.g. for 64bit? ==> http://www.microsoft.com/downloads/details.aspx?FamilyId=91672C7C-614B-404C-850C-377541E93C18&displaylang=en
"This comes inside SP1 for vista 64, as noted with my other system during the build. "
Better double check it.
Install all four memory sticks and do a memory check with >>Memtest86<< 1st, ensure that no error(s) will comes during testing.
Also how about that?:
Quote from: BOSSKILLER on 07-April-08, 23:55:36
Remove your OC then see how its goes.
"When the system boots in single channel mode (only 2 or 6gb of ram meaning 1 or 3 sticks installed into the 4 slots) its' rock stable. When it boots into dual channel mode (2 x 2 sticks or 2 x 4 sticks) extemely unstable. "
That means, timings are too tight, or they need a bit more vcore help, or some of the memory stick has failure.
"MSI P7N SLI Platinum - MS-7380 - Bios 2.0 on Vista Ultimate 64-bit - all updated."
That BIOS is not for your board, you should use 1.xx

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
