DDR2 1066 work with AM3 CPU?

Am I too stupid or what? Will an AMD Phenom 2 550BE work with a DDR2 1066? From what I understand the site listed "Supports Dual DDR2 667/800/1066 (1066 for AM2+ only)". But AM3 CPU will fit in an AM2+. It makes no mention of what AM3 memory will be supporting. Then I contacted MSI and got this response:
Thanks for contacting MSI Technical Support Team!
Regarding your concern,kindly please pay attention to the following link:
http://asia.msi.com/index.php?func=proddesc&maincat_no=1&cat2_no=&cat3_no=&prod_no=1443
It highlights the following information:
Main Memory
• Supports Dual DDR2 667/800/1066 (1066 for AM2+ only)
- 4 DDR2 DIMMs (240pin / 1.8V)
- Supports a maximum memory size up to 8GB.
Therefore,DDR2 1066 RAMs only support AM2+ socket.
Kindly please pay attention to the following AMD official website.It highlights that the socket of AMD Phenom™ II X2 550 is AM3:
http://products.amd.com/en-us/DesktopCPUDetail.aspx?id=560&f1=&f2=&f3=&f4=&f5=AM3&f6=&f7=45nm+SOI&f8=&f9=&f10=&f11=&f12=True
So I am a bit uncertain here.

Simple answer: YES!
Support for unregistered DIMMs up to PC2 8500 (DDR2-1066MHz) OR PC3 (DDR3-1333MHz), but 1 stick per channel!
DDR2 or DDR3 depends on the board.

My MSI KT3-ULTRA2 doesn't work with my CPU cooler!!

My MSI KT3-ULTRA2 doesn't work with my CPU cooler!!
I've got an MSI KT3-ULTRA2 mainbord, and I have a NEOLEC VENEZIA TB Cooler. But when I attach my NEOLEC cooler and I start the machine, the machine shuts down within a couple of seconds, and I get nothing to see on my screen. The weird thing is when I turn the PC on, the cooler starts rotating so it can't be broke, but then the pc shuts down i a couple of secs. So pleezze anybody help me!!
The weird thing is that I also have a coolermaster cooler, and that one works fine. But the problem is that this coolermaster is designed for AMD XP 1900+, and I ahve an AMD XP 2200+ that's why I bought the Neolec Venezia TB cooler.

one easy thing to watch for... see if the heatsink or fan is in contact with any part of the motherboard, like... if it is too big and touches something that normally wouldn't be in contact with a fan or heatsink. If so, it could be shorting it.

Haswell specific linux-ck doesn't work with Haswell CPU - Intel G3258?

I tried to install Haswell optimized linux-ck. Systems always freezes at boot, after kernel and init ram disk are loaded. After some time of troubleshooting I've tried generic linux-ck kernel and it works.

Despite being labeled as such, it doesn't have the full Haswell feature set. Among other things, AVX and AVX2 are missing. If the compiler generated code which uses AVX/AVX2 instructions, their lack can definitely cause the kernel not to boot.

Will Zalman's passive VGA-cooling work with their CPU-cooler on K8N?

I'm thinking of getting the
¤ Zalman ZM80D-HP VGA Dual Heatpipe
combined with
¤ Zalman ZM-7000A-CU
Will they both fit on a K8N? EDIT: What I'm asking is wether there is enough space to fit them both, not compatibility.
What other passive VGA-cooling will work/won't work?
Thanks!

OK, I'll think about that and read some reviews. I've allready read good stuff about it, just haven't considdered it, cause I thought 'why go low-noise if you can go no-noise', but since this cooler draws air out of the case, other fans could possibly spin slower, so it may be a contestant.

The 9800 Pro doesn't have any temp reader, but with the fan @ 5v it got really hot to the touch, now days I'm using a potentiometer controlling all the fans in the computer, and surfing the web etc it doesn't really matter if the GPU get's a little hot.
That was innovative! Don't have the guts to do such a thing though. Since I haven't bought my stuff yet, I'll rather play safe and try other solutions.

K9ND Speedster board won't work with opteron 2212

Hello,
Does anybody know if this board is compatible with opteron 2212? I am building a computer and when I plug both cpu's all I get is a black screen. If I plug in one cpu (it does not matter which one) the system boots.
Has anybody built a PC with this board using dual CPUs (Opteron 2212)? I checked the numbers and I have a matching pair. Am I missing something? I checked MSI's Qualified Vendor List and I don't see this particular CPU. They only show Opteron 2210, 2216, 2218, and 2220, does that mean that I can only used the CPU's on this list?
Please help!
Here is the link for the motherboard that I have. I have the workstation type, which does not have a built in VGA.

How are placed your memory sticks?
Do you use 8pin CPU power cable rather than 4pin?
Hello, thanks for the fast replies.
My memory sticks are placed in DIMM one and two of CPU 0 and it's working with one CPU. If I plug in both CPUs with I memory stick on each (DIMM ONE) or 2 sticks (DIMM one and two) the system does not boot.
I also noticed that If i plug in the 4 stick (4gb) of RAM in CPU 0 the system does not boot either.

Let's go simple with this one:
1. The bios is NOT the isue here. 1.3 simply works with the 2212.
2. You installed your stuff onto another K9ND Speedster and that booted. Was it a K9ND Speedster V1 or V2 that your friend has?
3. The board was RMA'd, right? Are you 100% sure that you didn't receive the same board back as you sent? Did you mark the old board in a way that you can actually tell that it was the one you RMA'd?
* Yes, I installed all the stuff to my friend's board and the same thing happened. He bought the board at the same place... :(
* Yes the board was RMA'd. I am sure that I got another one because the first board that I had before did not work with one CPU plugged in either and the new one does.
Quote from: Bas on 24-August-08, 22:22:54
You did connect all power-plugs properly did you?
Yes, I did. I plugged in the 24pin and the other next to it 8 pin.
Do you guys have any idea what could be wrong? Is it something that I have to change in the set up to tell the bios to accept 2 cpus or igb memory sticks? or is there something I have to change in the board on the board?
I really appreciate your help and effort. Thank you.

Updating Z68A-GD55 to ME8 with 32nm cpu

Board: Z68A-GD55 (MS-7681) 4.0
UEFI: American Megatrends Inc. V23.1 08/01/2011
3.30 gigahertz Intel Core i5-2500K 32nm architecture.
So my bios does not work with the gtx970, it still boots but in order to access it I need to update so it will support the card. Since I'm trying to overclock the CPU the bios could be quite useful, however I notice that on the update page msi only recommend going to ME8 with 22nm cpu. Is this simply because they see it as a redundant update otherwise or will it actually cause problems
The alternative is that I just wait a lifetime for the error splash screen to clear every time I boot and when I want to access the bios I change my graphics card over. This is obviously a pain in the ass but it's better than having a motherboard that won't work with my cpu.

A BIOS update on that board will make your overclocking of your 32nm (Sandybridge) CPU very limited to only the multiplier everything else will be very restricted and your overclock will be limited as a result as upping the voltage to it will be very minimal! (also the multiplier will be a little bit more restrictive too)
so its upto you if you want to try and update the board (NOTE: The update will make it so its impossible to roll back to a ME7 version)

K9N2 SLI Platinum BIOS v3.4 - Not compatible with DDR2 1066??

So... I've been going through OCZ Tech Support for about a month now.
I have a set of DDR1066 PC2-8500 Dual Channel ram. When I first installed it, and set it to run at 1066, I had nothing but problems and went through OCZ's tech support, went through a bunch of trouble shooting, and got an RMA on the set.
I sent it back to OCZ and it has been replaced with a new set, and I am still having problems getting this new set, to run at 1066 without it crashing constantly.
OCZ is now telling me that, since this is now two different sets of the same RAM, that is not working and refusing to run at 1066; but runs fine at 800... OCZ is now telling me that there is likely a problem with the BIOS on my Mobo not properly supporting 1066 Ram?? I'm running the latest BIOS of v3.4.
Is this possible?
I think I've read that other people are using this Mobo, with the same BIOS, and are having no problems with their DDR2 1066, correct?
Problem I am having is when I set my BIOS to run my ram at 1:2.66 for 1066; then try to run things like Crysis, Far Cry, SPORE, Second Life, etc... then the system constantly crashes. Everything else seems to run fine, Windows runs fine, internet browser runs fine, can watch TV, watch Movies and all this and never have problems.
But when I try to run a game; it constantly crashes but ONLY when I have the ram set to run at 1066.

Hello Bas.
I've tried all slots.
I'll repeat here, what I last posted on OCZ Forums in my latest thread there...
Ok.
For starters; through all the testing, the following settings never changed.
DRAM Timing Mode set to BOTH
Bank Interleaving set to AUTO
tRTP, tWR, tRRD, tWTR all set to AUTO.
1T/2T Memory Timing is set to 2T
DCT Unganged Mode is Enabled.
SLI-Ready Memory is Disabled.
NOW. The changes that were Tested.
Both Sticks in Dimm slots 1 and 2.
I've changed DRAM Voltage to v2.10 as advised. Still crashing.
Tried changing it to v2.20 next. Still crashing.
Changed it back to v2.10; and then set CAS, tRCD, tRP,tRAS and tRC to 5-5-5-18-27. Still crashing.
Left timings as previously set, changed to v2.20; still crashing.
NEXT.
Moved both sticks into dimm slots 3 and 4.
Left timings as previously set, changed to v2.10. Still crashing.
Changed to v2.20. Still crashing.
Changed to v2.00. Still crashing.
NEXT.
Left Timings as previously set. Voltage set to v2.10.
Removed 1 Stick from Slot 4; left 1 stick in Slot 3. Still crashing.
Switched sticks in Slot 3; Still crashing.
Removed stick from slot 3, placed same stick into Slot 1. Still Crashing.
Lastly...
Reset all settings to Default/Auto, set RAM back to 800mhz.
No more crashing.
At this point I do not know what else to do, and OCZ is telling me it is a problem with the BIOS that I am using. This is the SECOND set, of this same ram.

1a. I would take a look at what bios you have just new and which one is newer and update to this to minimize the risk of problems, I recommend yourself to use out
a USB memory device formatted to FAT or FAT32, and use >>Use the MSI HQ Forum USB flasher<< and do not flash with the LiveUpdate or M-Flash ... use our flasher, it still Holder a perfect track record of 0% bad flash!

DDR2 800MHz is working with G5?

Hi,
I read that latest G5 works fine with DDR2 PC4200 4200 533MHz, but in my local markets there are just DDR2 800MHz.
So is it going to work with G5???

Hi-
The G5 was made to us only PC2-4200 RAM. The G5 firmware does not look for any RAM other than PC2-4200.
Though other faster DIMMs may be backward compatible, if the SPD does not report properly to the G5 system (not properly programmed in the EEPROM), the RAM may be improperly recognized or not even work.
in my local markets there are just DDR2 800MHz.
*Buy only guaranteed Mac compatible RAM of the proper specification.*
Otherwise, expect problems.
If there are no problems, then you are lucky.

How to get new E8400 CPU to work with P965 Neo-F V2?

My old Core 2 Duo E6850 CPU died recently, but Intel doesn't manufacture that model any longer it seems and noone has it available. From the mainboard CPU compatibility list I could see that the equivalent E8400 model would work with my P965 Neo-F V2 as well, and the guy who sold it to me said it would. However, if I understand the compatibility list correctly, the E8400 CPU needs the newest 3.8 BIOS. I've never flashed the BIOS, so it's whatever version it came with (2.1 I think).
Is there any way to get this BIOS on the mainboard without my old CPU? I got a used (but working) E8400 CPU to try with, but it gets stuck at the first boot screen. I can't access the BIOS settings or get a keyboard to work.
Is there anything I can do with my current CPU and mainboard, or do I have to find a CPU that runs on the mainboard, flash the BIOS and then use the new CPU? Am I completely screwed?
Thank you.

do I have to find a CPU that runs on the mainboard, flash the BIOS and then use the new CPU?
Yes. Original BIOS would have been 3.0
Edit: This is best way to flash BIOS >> USB BIOS flash << Don't use 'Live Update'

K9N2 SLI using ddr2-1066 memory

I am about to purchase the K9N2 SLI motherboard and noticed it has a memory rating of 1.9v.
But when looking for ddr2-1066 memory to use with an AM2+ processor, all I can find is 2.1+v memory.
Msi says the board is rated for 1066 yet there doesn't appear to be any memory manufactured within that range. Anybody know if the 2.1v will work?
I didn't think you could use a higher rated voltage.

Quote from: Stu on 05-August-08, 06:25:23
Yes, it will work, if needed you'll be able to raise the memory voltage in BIOS settings.
No, it will not work. It won't even work with the updated bios version (3.3). I currently have this Motherboard and have been working with MSI to resolve this issue and one other issue.
I am currently running a AMD Athlon 64 X2 5400+ Black Edition. My memory is Crucial Ballistix Tracer DDR2 800 4x1GB. The memory is 4-4-4-12 at 2.1. The bios will not automatically set this and you have to manually set the timings and voltage and when you adjust the voltage higher than 1.9 it forces the memory to run at 400mhz rather 800mhz. So technically it will allow you to set the voltage higher, but it will only allow the memory to run at half speed. This motherboard also will not allow you to adjust the CPU multiplier. I have tried both the AMD Athlon 64 X2 5000+ Black Edition and the 5400+ Black Edition, and regardless of what you set it at, it will not take effect at all. I have tried both processors in a Gigabyte board and the Gigabyte board will allow you to adjust the Multiplier (CPU RATIO).
Also, if you attempt to run any memory that runs at 2.0 or higher, MSI will not provide you with technical Support.
MSI's response to my memory issue:
The memory you are using requires a voltage of 2.1v, the K9N2 SLI Platinum only supports up to 1.9v. We cannot assist you with this situation any further.

MSI DKA790GX Platinum and AM3 CPU - BIOS Update

Hi,
I am going to upgrade my current computer from an older AMD socket 939 setup to an AMD Phenom II based system
I am thinking of the MSI DKA790GX Platinum motherboard and AMD Phenom II X3 720 (Black edition) CPU (AM2+ Motherboard and AM3 CPU), but I need to clear up the BIOS update for AM3 issue before buying the components.
The motherboard advertisement states that the BIOS has to be upgraded to support AM3 CPU
My issue is this: I do not have an AM2/AM2+ CPU, and I am looking to jump right into buying an AM3 CPU - so will the unit power-up/POST with the combination of the newer AM3 CPU and older BIOS to allow me to update the BIOS using either FDD or Bootable USB Pen in a DOS environment?
Does anyone have any knowledge or experience of this? Any help on this would be appreciated
Thanks

The 1.74 Bios is one I got from MSI tech support. We're trying to work through a problem with my new board. nothing major, but we're not quite there yet.
I know that Nvidia was The chipset to have for several years, but I think AMD has upset that applecart a bit with the 780 & now 790 chipsets, and with Intel
getting into the chipset game as well, Nvidia could see some rough times ahead. They may even end up dropping out of the chipset game, since Intel's new CPUs have the memory controller built on die. Hence, Intel has no real need for NVidia any more, Nvidia may end up just focusing on the video card market, unless?
My board defaults to 800mhz as well and I'm running a 720. You have to keep in mind that they have to make the boards default to the lowest common denominator as not everyone runs 1066 capable memory on their board (even though Manufacturers may spec the memory so). I also have to manually bump up the voltage, as well as timings and ratio for 1066. But, my Mushkin ram plugged in and booted with no problems, but I did have to bump up the voltage and tighten up the timings even at 800.
Interesting (Abut BIOS version 1.74). I guess it is not yet available for downloads.
So now Intel CPU's have the memory controller on the die (just like AMD). So does this prove as an advantageous concept? I expect Intel to implement better memory management than AMD. AMD drops speed when all 4 memory banks are occupied... what is the use of utilizing max RAM capability if memory controller cannot sustain the max RAM speed?
I may agree with you on the concept that motherboard should support the lowest (RAM) denominator...
However if someone uses lower than 1066 MHz sticks, system should detect accordingly, and when 1066 sticks are used, auto-detect as 1066... I still do not see the issue here. On former nVidia based boards like my MSI K9A Platinum SLI (with an AMD X2 CPU), 800 MHz modules are detected as 800 on auto, no need to manually tweak anything in BIOS. I still have to see an nVidia EPP profile enabled board which is claimed to auto detect 1066 MHz capable memory sticks by default.
On my system it is also the same... I have to up the RAM voltage to 2.2V (otherwise system is not stable), as well as setting up the timings and of course the RAM/FSB speed ratio to 1:2.66.
I am running currently 4 chips of OCZ platinum 2 GHZ (for a total of 8 GB RAM, for 64 bit Vista and Linux). Also with mine (as we know Phenom II does not support 4 sticks of 1066 MHz) it drops to 800 MHz. As well as, I needed to bump the voltage to 2.2 V... otherwise in the middle of operation, system reboots. We know what this is about, dont we ?

MSI P43 NEO-F, Q9400, GSkills 4GB DDR2-1066 unstable... help!

Just built a new system with the following hardware:

Motherboard: MSI P43 Neo F (1.A or 1.10 BIOS)
Memory: G Skills 2x2GB DDR 1066 5-5-5-15 (F2-8500CL5-2GBPK) (running @ 800 2.1v only, not stable at 1066 2.1v)
Video Card: MSI ATI R4870
PSU: OCZ GameXStream, OCZGXS700 7OO watts, 4x +12V@18A outputs
Cooling heatsinks are all stock, but air flow is good with the new TT case.
Current voltage settings:
CPU Voltage: 1.335V
CPU GTL REF0: Auto
CPU GTL REF1: Auto
DRAM Voltage: 2.1V
MCH or NB Voltage: 1.328V
VTT FSB Voltage: 1.2V
MCH GTL REF Voltage: Auto
ICH or SB Voltage: 1.5
Does anyone have the similar setup or any idea why I can't get the system running at 3.2GHz @ 1600FSB and 4GB @1066MHz ?
I've ran multiple tests with PRIME95 and Memtest64, and was unsuccessful.
System actually got through Prime95's small and large FFT test OK, but failed the Blend test. So I'm leaning towards the memory.
But I got LOTS of errors from Memtest86, while memory set at 1066 @ 5-5-5-15 2.1V
What voltage should I be tweaking the CPU, NB and SB to get the RAM to pass Memtest?
I'm not asking much, but it seems these overclocked DDR2-800 RAM aren't that stable at 1066 without tweaking other components. B/C the system definitely wasn't stable with CPU/FSB @ stock speed and RAM set at 5-5-5-15, 1066, 2.1V
Don't know why they call it DDR2-1066 when it only runs stable at DDR2-800...

The P45 Memory controller natively supports only DDR2-667 and DDR2-800 modules. From the point of view of the chipset, DDR2-1066 is beyond specifications. Also, your memory modules are just DDR2-800 sticks with a permission to overclock, not native DDR2-1066 modules, built to work @1.8V.
This double overclocking makes a stable system @DDR2-1066 somewhat of a hit & miss situation.
Do you have options to tweak the DDR Reference Voltage Values in BIOS?
Nope, I didn't find a DDR Ref Voltage value.
Hmm , I thought the MSI specs posted would mean the chipsets and mainboard can sustain double overclocking...
Cause the memory module report on the MSI website actually has my memory set, and results were OK when operating at DDR2-1066.

I wonder what settings they used...

DDR2 1066 work with AM3 CPU?
