MSI GT72 memory upgrade/dual channel question
I just recently purchased a GT72 2QD laptop which has 12GB of ram installed (with 1x4GB module and 1x8GB module). The RAM is shown as running in dual channel, but it is asynchronous and I'm getting inconsistent memory bandwidth results when testing bandwidth with AIDA64. My question is, would I be able to buy an additional 4GB and 8GB module (I'm looking at the Kingston value ram), put them in the two free RAM slots inside the chasis and run the RAM in synchronous dual channel mode? If so, which slots should I put each module in to get the ram to run in proper dual channel mode? I would appreciate any help y'all can give me.
hope this information will help you...

quoted from Intel website above:
Rules to enable dual-channel mode
To achieve dual-channel mode, the following conditions must be met:
Same memory size. Examples: 1 GB, 2 GB, 4 GB.
Matched DIMM configuration in each channel
Matched in symmetrical memory slots
Configurations that do not match the above conditions revert to single-channel mode. The following conditions do not need to be met:
Same brand
Same timing specifications
Same speed (MHz)
The slowest DIMM module populated in the system decides memory channel speed.

Memory and dual channel problems
Hi
Can someone help me?
1- I have 2x512 MB DDR 400 Twinmos CL 2.5 and amd xp 2600 (fsb 333) and Msi K7n2 delta L. I have tested separatly my sticks, one of them woks great, if i put dram clock at 166 or 200 the sytem is always stable. The other stick is not so great , if i put him at 200, most of times the sytem doesn´t boot and the lights in the d-bracket display memory problems, when it manages to boot, when i get to windows i´m always getting blue screens with error messages. If i put to 166 it´s more stable, but sometimes hapens the same, but less frequently.
I have run memtest, but it shows no errors in both sticks.
2- When i use both sticks together in dual channel dimm 1 & dimm 3 sometimes windows only displays 512 MB, but if i reboot the sytem, i get 1 GB as it should be.
It is not frequently, but sometimes it hapens.
3- How can i detect dual ddr is working or not?
I´m asking this becouse the two sticks i have are similar, but there is a little diference, one of them has twinmos chips and the other has M.tec chips. But both are from Twinmos. Sisoftware sandra shows them as equal.
I have heard that this mobo, on the boot screen should display something like this:
Memory Mode: Dual Channel
or
Memory Mode: Single Channel
But in the boot screen it only says DDR 400 or DDR 333 acording to the setings i have put in the bios.
My bios version is 5.1 (4/18/2003). Do you think i need to flash the bios?
Thanks

Single Channel Dual Channel Question, K8N Neo4 Platinum
Just putting together a machine for the Daughter. Using MSI K8N Neo4 Platinum board 7125-010, MSI NX6600GT PCIE 128 Video card with AMD64 3700 CPU SD and a 1 GB stick of Crucial dual sided memory, CT12864Z40B, DDR 400 3200. The rest of my parts arrived and just got it all together and booted into the Bios. The boot screen tells me the memory is DDR Single Cannel, 64 bit running at 3-3-8-3 and 2T timings. I have been into the Bios setup, but had let the memory boot at Auto settings. Is what I am seeing on this screen OK because there is only one stick of memory installed? Or am I just confused as normal? I was thinking it should read Dual Channel, but I am hoping that is just my backwards thinking at times. I wish all a very Merry Christmas and a Happy New Year. Thanks in advance for the guidance.
Pop'sJayBee; Thank you very much for the quick response. The Daughter decided to go with the 1GB stick to begin with so as to possibly add another 1GB stick later. I don't think she will need it myself, judging by her computer use. She does no gaming or multi-tasking, so there probably will be no need to add more memory in the future. I was just wondering if there is any noticable performance hit by using a single stick vs a pair of matched 512's?? I used the same MB as in my sig, but noticed the new one has an upgraded BIOS. I hope it is an improvement, because I have yet had no problems with my machine which has the V1.6 BIOS. This new one which is about 2 months newer than mine has a BIOS V1.A in the bios screen. At bootup it is identified as ( 6A61FM49C-OO ) what ever that means. I read the forum daily and have noticed you are very active and consice in helping folks out. I very much appreciate your time and effort that you give freely. Hope you have a very safe and happy holiday season and SANTA is very good to you. I think we as a group need to get SANTA up to speed on gift giving in the computer upgrade department.

Hi everyone, i am new to this forum and this is my first post. I have, however, been reading posts for a bout a week or so as i have benn trying to find answers to some of my questions.
Here is my spec:
K8T Neo2-FIR pro motherboard
Athlon 64 3800+ CPU (venice core)
512mb kingston ram x 2 (in sockets 1 and 2)
Geforce fx 6600gt graphics card
First of all, i just wanted to say that this motherboard (in my opinion) is FAST!
I can only run my memory in single mode as i now know i don't have the right BIOS ver. I am too scared to flash it manually so i will stick with ver 3.3.
However, i had the chance to swap all my components into another brand new Asrock motherboard. The duel channel work straight from word go. I ran Aquamark 3 and i was getting a score of 25,000. Yet, on the MSI motherboard, in single channel mode i was getting 52,000.
So i swapped back to the K8T Neo2!
The plot thickens ..... a friend of mine also has this board but he doesn't have the venice core and therefore he can run it in dual channel, but, he only gets a score of 48,000 and that's using my components, same ram, graphics etc.
So here's my question:
Is it worth me flashing my bios to 9.2 and will i get better scores in games and better frame rates in games? .... the manual flash seems complicated and risky. I used the live flash to get 3.3a when i first got the board and that worked fine. If only they let you select which ver you wanted to live flash.
Last of all, i wanted to say that some of you have taught me quite a bit about my pc and i may even attempt overclocking (a little) one day. Tiresmoke you deserve credit for your help and work on this forum.Quote from: Killawife on 19-November-05, 06:48:13
Im sure its the safest but didnt work for me. The winflash works fine as long as you know what you are doing and dont have a windows that does things you dont want it to.
Yabbot Killawife, consider what redfox62 said:

You still think that's good advice considering red's trepidation? I can understand if you could be there to look over his shoulder and direct, but you're not unfortunately.

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 -
Hi,
Just want to know.....i have 2x512(matched pair) DDR 400 , how can i be sure that im working in dual channel ?
And if i add more 512 in the third ram slot ill still work in dual channel ?
ThxQuote
to use dual channel you MUST have the same amout of memory in slot 3 as you have in slot 1 and 2.
Well if so then why is it that before I got my second lot of 512Mb of ram I had 512 in slot 1 and 256 in slot 3 and it was running in dual mode.
Then later I put 512 in 1,256 in 2,and 512 in 3 and it was still dual mode.
I have even had 256 in 1,512 in 2 and 3.
Regardless of where I put them it still runs in dual channel mode. -
Hi
I've recently tried installing a single stick of 128Mb PC133 RAM on to my 6178 but it only detects it as 64Mb. All the chips are on one side of the stick.
I was hoping to flash my AMI BIOS (ver 1.9) with a Award 2.1 BIOS, but i keep getting a "The program files part number does not match with you system" message.
What am I doing wrong? Am i going about this the right way?
Any help would be most appreciated.
Cheers
JigsawI have the same problem with MS 6163by master. it is very difficult to find a sdram that will work good on our old pcs. I tryed so many different rams... now i have 512MB working ram. I was hope to get more but...without sucess. If you look in your book of motherboard you will find the information which rams are supported and how many chisps it must have attached on it.
Good luck ! -
645 ultra - Dual Channel Memory?
Just Finished Building my system about 2 weeks ago. I was wondering if the MS-6547 is capable of running memory in dual channel mode?

Full system virus scan, and clean out.
Clean Boot,
Re-Set Ram CPU ratio down to give 266Mhz.
Turbo Ram Timing.
Ram Latency CL2
Ras/Cas Normal.
Al of which I was backing off, but rightn now seems to hold up
I was able to wind the FSB up to 118Mhz, clocking me at a mear 2.85 Gig (which for some reason is higher than 118*24)
the good thing here, is when the system did crash at 120, the bias did not re-set! which was happening in the past.
At 120 I got quite a lot of graphical artifacting, but my gcard was running hot since the air temp here is at about 25/26C with sumer approaching (don't help does it!)
Anyway, I'll be ticking off a few more tweaks tonight.
I did notice that this did NOT improve Aquamark, but added 1000 points to 3dMark2001, from taking it from 11500 to 12500. Benchmarks moving more from CPU/GPU to GPU only dependant. Codecreatures is a good bench also -
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.

Ok, here is the story
My notebook is HP Probook 4520s
with Windows Windows 8.1 (6.3) 64-bit (Build 9600)
Please refer to the end of this post for CPU-Z report of specs.
Currently I have 3GB of memory installed -had to install them back after upgrade failure-.
Please refer again to the CPU-Z report for the memory module specifications.
I bought the following Corsair 2x4GB memory pack

When I installed the memory module onto the notebook, I basically couldn't go beyond the POST stage. That is the HP logo appears on the screen, and that's it.. that's it.. nothing beyond that stage.
When I went to the BIOS settings, the memory successfully read 81xxMB, this is basically 8GB of RAM.
I tried to reset BIOS settings, failed again.
I removed the 2x4GB modules, put back both original 1GB and 2GB modules -the ones that came with the notebook-, everything worked again.
What went wrong here..?
P.S. please do not reply with lame replies like "that's weird" "that's strange", I know it's weird and strange. I want specific and clear suggestions.

MacbookPro will not wake up from sleep after memory upgrade
I am restarting this topic as I have read thread after thread (many years old) and they all just die off with out any definite solution.
I have a 13" Mid 2010 Mac book Pro which originally came with 250gb HDD and 4gb memory
I have recently upgraded to a 256 SSD and a 1TB HDD optidrive replacement along with a 8GB memory upgrade and I am now running Lion 10.7.4
If I close the lid and open within approximately 1 minute it will wake up quickly as normal, if I leave it asleep for a minute or 2 it will not wake up with out holding the power button for several seconds and then I still need to wait a several seconds for it to respond and actually wake up. Sometimes I will need to completely shut down and restart. If I wanted a computer that takes forever to wake up I would have a PC!
The last thing I upgraded was the memory so I am sure it is the cause of the sleep problem and not the SSD conversion which was working fine with the original 4GB mem before upgrade.
I have read about resting the PRAM, resetting PMC as well as executing a line in the terminal, but all of these seem to have variable success. I have tried every thing but using the terminal to adjust the hibernate mode setting as I am not proficient with terminal and don't actually understand what changing this setting does (sudo pmset -a hibernatemode 7).
Has anyone resolved this sleep problem and what did you do? I would greatly appreciate some knowledgeable insight on the hibernation settings, and what running the line in the terminal is actually doing... even better what is the default so I can change it back if it doesn't resolve the problem.
A simple memory upgrade causing such a issues is very irritating.... Any help would be greatly appreciated!But still, the sleep issue persists, so it is a more subtle timing issue. I upgraded my MBP with a Corsair 8GB kit ( http://www.corsair.com/us/corsair-mac-memory-8gb-ddr3-sodimm-memory-kit-cmsa8gx3 m2a1333c9.html ) and it indicated it had 9-9-9-24 CAS timing. It has worked flawlessly till now. Note that my Mac is a Late 2011, whose memory runs at 1333 MHz.
As far as I can tell, the 13" Mid 2010 models used 1067 MHz memory with 7-7-7-20 CAS timing: http://www.corsair.com/us/corsair-mac-memory-8gb-dual-channel-ddr3-sodimm-memory -kit-cmsa8gx3m2a106c7.html -
Can't get Dual Channel mode to work
Hello,
I have a pair of 512MB DDR400 ram sticks (listed in my sig).
The Memory Slots are arranged like this:
1 2 3
[cpu] | | |
I put each stick in slot 1 and 2 and no workie, still Single Channel Mode.
I put a stick in slot#2 and #3, no workie.
I put a stick in slot#1 and slot#3, no workie.
Is there something else that I'm missing or did I just buy the wrong memory for dual channel operation? It was not a matched set, but it is the same no-name brand of memory I bought from newegg.com. They both have the same 3225804T-5 marking on them...
They are supposed to be 2.5CS and that is what my bios is set to. I don't have any special settings in the bios that I know of..
Let me know if you have any ideas or if I need to post more information.
Thank You!K7N2-V
Not sure about this but is that motherboard based on the Nvidia nForce2 400 chipset?
What does the manual specs say?
If it is then it doesnt have 2 memory controllers and can only do single channel.

K8t Neo2 won't run dual channel with Opteron 165
Hi,
I have a K8t Neo 2, and was running a Newcastle 3500+ on it, with 2x1GB PC3200 memory sticks (Buffalo memory) in dual channel mode (ie DIMM 1 and DIMM 3 populated) without any problems. I replaced the 3500+ with a new Opteron 165, and the system would not post. One of the red lights on the D-bracket was red, the rest were out.
To troubleshoot, I removed one of the memory sticks, and the system booted fine. I then put the 2nd memory stick in a non-dual channel setup (DIMM 1 and DIMM 2 populated), and it booted fine. If I try booting the system with the RAM in any dual channel enabled configuration, it will not post. I verified that it isn't a RAM issue, because I have 2 sticks of 512 MB ShikaXRam, which has always worked fine, and I got the same behavior as I got with the Buffalo RAM. I have tried changing the RAM clocking in the BIOS, and that also doesn't help, because it seems it reads the speed automatically no matter what you set the DRAM clocking page to.
Does anyone have any suggestions? Is this board not Opteron 165 compatible with dual channel memory?Alright, I tried all of the steps mentioned, setting optimized defaults, even tried changing all memory timings to the most conservative available. The only way the system will boot with 2 DIMMs installed is if they are in the two slots furthest from the CPU. It will also post with 3 DIMMs installed in any configuration.
I also have a generic 500 w PSU that is rated 32a on the 12v rail that I tried quickly plugging in (just plugged the 2 PSU connectors to the motherboard without hooking any of the IDE devices to it) It still exhibits the same behaviour. With no hard drives, optical drives, etc plugged in, wouldn't that pretty much eliminate the PSU as an issue?
I don't want to just spend $100 on a new PSU if it's highly unlikely to be the issue. Does this sound like something I'd need to replace the motherboard to fix? Is the performance difference between dual channel and single channel enough to even warrant buying a new board? The reason I want to avoid replacing the board right now is because I still have an AGP card, and don't want to replace it right now as well as the board, and getting another AGP based board seems to be stupid. Also, AGP boards are really hard to find now, and most of them available locally run on the ULi chipset -
[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 p4n diamond and memory module setup for dual channel reading
hi,
ive just built my mum a pc using a msi p4n diamond mainboard which has 2 gig of ddr2 667 mhz memory, just wondering how to go about setting it up to dual channel as its currently showing up in boot post screen as being single channel.. Now correct me if i'm doing wrong but it has 2 green slots and 2 orange slots, should there be 1 stick of ram in green and one stick of ram in the oarnage slot to show dual channel or both sticks as they are situe at present in green slots please..
system spec is below..
mainboard - msi p4n diamond
cpu - intel pentium 4 @stock speed 3.0 ghz HT
geforce 8800 gs @ 512 meg of ram
500 gig s-ata hard drive
600 w coolmaster psu
2x1 gig kingston ddr2@667 mhz
first release bios
thank you and hope you can advise me..It's in the manual, if you don't have one you can download from here:
http://www.msi.com/service/download/manual-4385.html
If both sticks are in green as you say then yes it's single channel. For dual channel you want to leave 1 stick in DIMM1, green slot nearest CPU & move the 2nd stick to the orange DIMM3 slot.
From left to right DIMM1/2-green, DIMM3/4-orange, dual is 1 stick DIMM1 & 1 stick DIMM3 or 1 stick DIMM2 & 1 stick DIMM4 or 4 sticks all four slots filled. Single channel is 2 sticks in green slots or 2 sticks in orange slots or not recommended is 3 sticks in 3 of the 4 slots.
