AM2+ MoBo using AM3 Processor

[Nobodygood>XI<]

I normally build a computer for myself once a year, but I have been so happy with this one (built it in 2008)

I want to keep it.

I see that I can use a AM3 processor in mine with a bios update "kool"

I know I will loose about 5% using DDR2 memory, but a 6 core 3.2 Ghz processor would make a world of diff I would think

I do have a new ATI6850 graphics card, so I think this would be the ticket

I have a MSI k9A2 Platium and would have to say it has been the best motherboard I ever used and I have used every major brand you could think of

 

Question

Has anybody run the AM3 in a AM2 board?....no guessing please just those that have done it.

If so, how do you like the combo?

[Nobodygood>XI<]

so nobody has done this?

so I guess I will be the one to check it out

[Kisses4You]

can you test it,pls. I have also an MSI, the DKA790GX Board. I will buy the AMD Phenom II X6 1090T, when the price will be a lil better for me :-P

 

[Nobodygood>XI<]

yah I am looking at the 199.00 mark before I want to pull the trigger

[Gump]

Doesn't that board only have 4pin cpu power?Would a PhenomIIx6 run stable on just a 4pin cpu connector.I think max for a 4pin is 125 watts

[Nobodygood>XI<]

acording to the specs it should be fine

and the processor

AMD Phenom II X6 1100T Thuban 3.3GHz, 3.7GHz Turbo 6 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Six-Core Desktop Processor HDE00ZFBR BOX

the board list that it will handle 125 watt processors

[Nobodygood>XI<]

I just ordered one from Newegg so will see in a few days if it was worth it

[DREAD69]

Not sure about my old board the Crosshair Formula III I will have to check but I am sure the board did not support the 6 core till I updated the bios. I was a DDR3 board though. My system ran fine with the old 790FX chipset but with the new 890 I got an extra 200MHz stable in my Overall stable OC.

 

EDIT: Just checked it was a AM3 but on the old chipset.

 

HERE IS THE MOBO

Sry could not be better help.

[simplemod]

did that a couple years ago, in a single core build, it was a barebone kit that came mixed that way. lasted about a year and the mobo fried the capacitor cans right next to the cpu. was MSI brand board. don't know what caused it. was NOT overclocked, and using the fan that came with the kit. did another barebone kit to replace it, pretty sure the cpu is AM3 at the moment but cant remember for sure if the new board is AM2 or not, but this bulid is a dual core 2.66ghz, and working great still after about a years and a half. i have 4 desktops up and running, can't be exactly sure of everything, will look at specs in a little while to be sure for you.. do know Im running ddr2 and vista x64 on that particular desktop build. that is the rig i have set up mainly for tv tuner card with a VHS vcr hooked up to it for home movie ripping.

[simplemod]

ok, sorry the replacement was this proc  AMD Athlon II X2 215 which is AM3 2.71 Ghz dual core : http://www.tigerdirect.com/applications/SearchTools/item-Details.asp?EdpNo=5241622

on this asustek m2n68-am se2 which is an AM2. sure it's not a six core, and I didn't have to update bios, but its been running for a while with no probs getting a windows score of 5.0 subscore on the aero desktop with an old 9500GT 1Gb card and 3Gb dual channel ddr2 (rates 5.3 on gaming graphics), it's no power house, but it does the job for video stuff and just watching tv. hope this helps you in some way.

Nobody.. looks like MSI has a bios update on your MOBO for the AM3 1090T... but I don't see one for the 1100T. Maybe you will get lucky and it will work, but don't bank on it. Here is a link to that page (you probably have it already, but here goes)

 

http://www.msi.com/product/mb/K9A2-Platinum.html#/?div=Download

 

According to everything I can find to read on it, AM2 boards can be compatible with some AM3 chips.. when the board manufacturer supplies a bios update. Like Dread said, the 6 cores aren't supported without it.

 

Good Luck!!!

 

I bought the same exact processor you just ordered. I run it on a ASUS Crosshair Formula IV board. I love it.

 

[Nobodygood>XI<]

Well they are both Thruban processors they both are 6 core They are both 125 watt they both have turbo they both have the same L2 and L3 so I would guess at worst it might under clock

 That was a common problem with alot of motherboards a few years ago, the cheaper the board the cheaper the caps.

I had an Abit MoBo I loved years ago that the caps swelled up and died on.

The caps on this board look a little more robust. The thing is that by the time the caps cooked most people were on to their next system. I think alot of us are hanging on to our computers longer than in the past.

I used to build myself a new one every November (at least new MoBo processor and memory) When I put this new processor in I hope to run it for at least another year. keep in mind my systems tend to morf, I added a 6870 vid card about 6 months ago

[Nobodygood>XI<]

Well I must of been thinking the same because when I looked I ordered a 1090T

But it is installed and with a little tweaking I have the system running nice

I ran Black Ops on a busy server tonight and I was hovering around 100 fps, damn nice compaired to how it was running

I think my hard drives are the only thing holding this system back.

I think the next thing I do is gang a SSD drive with on of my machanical drives, should double the transfer rate

[SpitFire]

i am running the x6 t1100 cpu and a gigabyte GA-870A-UD and it runs just fine and it gives me a lot of fun runs a little warm on the standard fan and i think i will replace it with a aftermarket cooler soon

Yeah, I put the Corsair H70 on my T1100 and it hardly ever sees temps above 35C now (no OC at the moment). I was considering the Thermaltake FRIO if I was going with just fans, but I like the H70 self-contained water system.. but it's a bit pricey.

Some cool comparisons with fan units in this review.. good read if you are trying to decide on aftermarket cooling on CPU.

Well been running it for a few weeks now and I am pretty happy with it.

One issue I have not cleared up yet, I am running my 1066 memory at 800.

If I run it at 1066 sooner or later I blue screen.

I also run Vista 64... yah I know...yuck!! but for those of you that do, I have found a way to install DX 11... yah baby

[LaRSin]

you could try uping the voltage on the ram

What you need to do is:

 

Download CPU-Z and click on the Mem-Tab (SPD). In there you can see what voltages are needed to run the memory at 533 (1066 Double rated). For example if it is 2.1Volt, you go to your BIOS and check if the memory runs on that voltage. And check the latency's.

 

Mine can handle 1066, but I have the stuff overclocked  :

 

 

 

 

 

[Nobodygood>XI<]

thanks for the tip, I was going to bump up the voltage on the memory anyhow but I think I will run that ap and see

[Nobodygood>XI<]

well, tried tweaking memory voltage and timing and still blue screen at 1066,,,,, kinda pisses me off since that is what the memory should run at

[CplMOFO]

well,

 

You can always download MEMtest86+, burn the image on a disk, using imageburn, go in BIOS to set boot priority to CD drive, put the disk in, reboot....

 

It's a MS-DOS utility, so it runs before WINDOWS...it's why you have to boot on the CD to read the software first..

 

MEMtest86+ will scan the memory 100% and let you know if there is issues with the RAM...

If you need help on that let me know, it's simple.

 

You "might" have one bad stick, or a bad memory slot...you might want to try with one stick at the time to run MEMTEST86+, try with different slots, to isolate the problem...

[Nobodygood>XI<]

well the RAM worked fine with the AM2 processor at 1066 but not the AM3 processor

I think it has more to do with the processors memory controler

I found this

VERY IMPORTANT INFORMATION REGARDING AMD AM3 CPU's and RAM SPEEDS There have been a lot of instances where members have been unable to obtain the stated speed of their RAM especially if it is faster than 1333 Mhz. In an effort to address these problems I have undertaken a lot of research and testing to come up with some honest answers for those of you experiencing such issues. The following comments are not those of Gigabyte or AMD but are my own, based on the research I have undertaken and the questions I have posed to both parties in an order to gain a greater understanding of the subject and are, to the best of my knowledge, correct at the time of posting. First off you should understand that this is not due to a problem with Gigabyte Motherboards or the BIOS. Other manufacturers boards also have the same problems. It is due to the Memory Controller on the AM3 CPU's which, by design, are set for 1333 Mhz memory modules or slower. That doesn't mean that you can't run 1600 Mhz RAM or, even if you do, that you are entering the realms of overclocking (although it can seem like it) but, it does mean that you need to understand the inherent problems of running your RAM above 1333 Mhz. on these Processors. This problem is more noticable if you are trying to run with all 4 memory slots filled on the motherboard but can also apply if you are only using 2 sticks of RAM. Having actually talked to an AMD Technical Guru to establish their views on this subject, I can now state, with confidence that: You are better off not trying to run your RAM above 1333 Mhz. when using an AM3 Phenom or Athlon CPU. If you do so, you run the risk of system instability and even damaging the Memory Controller on the CPU. If, like me, you have invested in 1600 Mhz RAM, you will actually benefit from running your RAM at 1333 Mhz and tightening the timings. You also gain better performance by slightly overclocking your CPU. If, however, you do overclock your CPU, it is stongly recommended that you purchase a good quality 3rd party CPU heatsink to aid CPU cooling and also remember that officially, neither Gigabyte or AMD support overclocking of their products. If you wish to run RAM above 1333 Mhz. and your RAM is rated at a higher speed, you are not overclocking your system. However, AMD recommend that you only use memory that appears on the QVL as this has been tested for compatability at higher speeds. If you are unsure about the compatability of the RAM you have bought the safest option is to run it at 1333 Mhz to avoid damaging the Memory Controller. If you are looking to buy RAM that is faster than 1333 Mhz. and it doesn't appear on the QVL be prepared to downclock the modules to gain system stability. There are no guarantees that the RAM will run as stated and you could possibly damage the CPU's Memory Controller. THIS IS VERY IMPORTANT: If you do manage to get your RAM running over 1333 Mhz., your system can appear to be fine and might even pass Memtest and other benchmarking utilities successfully. However, AMD have discovered that, in certain scenarios, the system may fall over after a period of use, depending on system usage and if you are stressing the CPU. This normally indicates a problem with the Memory Controller and you may need to replace your CPU if this happens. Excessively increasing voltages to the RAM and/or CPU in an effort to improve system stability could cause the Memory Controller to fail. AMD recommend running RAM in Unganged mode. From my own testing, RAM above 1333 Mhz can be extremely fussy if you insist on trying to run in Ganged Mode and will often return an Overclock warning at start-up and revert to 1333 Mhz., by default. In most modern mult-threaded applications there is actually no loss in performance when running in Unganged Mode and, in some instances, Unganged mode is actually superior. Some of the Athlon CPU's have a memory speed rating of 1066 Mhz and will pull back RAM above this speed to the default setting. This is again to protect the CPU's Memory Controller and is not a fault with the Motherboard, BIOS or RAM. The lack of easily available, clear and concise information regarding the AM3 CPU architecture and in particular the Memory Controller on these CPU's has led to a lot more problems than there really should be. It is understandable that AMD don't want to shout out too loudly that their AM3 CPU's do not handle the faster RAM speeds efficiently but it really hasn't been helped by the lack of information from all of the motherboard manufacturers regarding this subject as well. I hope this helps those of you facing such issues and, if you are looking to invest in an AMD AM3 CPU, an understanding of what to expect and which memory speed to be looking for. This ties in with another thread on the forum. Please check here for more information: http://forum.giga-byte.co.uk/index.php/topic,2379.0.html A LITTLE CLARIFICATION REGARDING GANGED/UNGANGED MODES & SINGLE/DUAL CHANNEL CONFIGURATION. Ganged Mode and Unganged Mode are not the same as Single Channel or Dual Channel configuration. The Ganged/Unganged mode refers to how the RAM Modules actually talk to the Memory Controller(s) on the CPU. Single or Dual channel configuration refers to how the RAM is installed in the memory slots on the motherboard. With one stick of RAM you are using single channel mode. With two sticks of RAM you can run in either Single or Dual Channel mode depending on how you fill the Memory Slots on the motherboard. If you use three or four sticks of RAM you will be running in Dual channel mode. On Gigabyte's AMD Boards there are two channels, each of which address one of the two memory controllers on the AM3 CPU. Channel 0 normally equals the Memory slots on the motherboard identified as DDR3_1 & DDR3_3 whilst Channel 1 normally refers to DDR3_2 & DDR3_4. If, for example you have two sticks of RAM and you put them into slots DDR3_1 & DDR3_2 you are running in Dual Channel Mode, each stick of RAM talks to its own Memory Controller. If you put the RAM into slots DDR3_1 & DDR3_3 you would be running in single channel mode, where both sticks of RAM are only talking to one of the Memory Controllers. (You would need to double check with your motherboard's own manual for correct Memory Slot Channel configuration) Ganged Mode is where you utilize both Memory Controllers on the CPU as a single unit giving you a single 128 bit channel. (You may not be able to run RAM faster than 1333Mhz in this mode. I haven't been able to with either the X4 965 or the X6 1090T.) Unganged Mode is where each of the Memory Controllers on the CPU work independently and equals 2X64 bit Channels. (I can run my RAM at 1600 Mhz only in this mode) If you have any comments or questions regarding this article please post them here: http://forum.giga-byte.co.uk/index.php/topic,3061.0.html Edited: 09/10/2010 Logged Remember, when all else fails a cup of tea and a good swear will often help!

Re: VERY IMPORTANT INFORMATION REGARDING AMD AM3 CPU's and RAM SPEEDS « Reply #1 on: August 10, 2010, 08:20:56 am » Quote The Phenom II only supports 1333MHz DDR3—at least, officially—with a single DIMM in each memory channel. With four DDR3 DIMMs, 1066MHz is the standard. Such limitations are nothing new, of course. Previous Phenoms have long supported 1066MHz DDR2 memory, but only with a single DIMM per channel.

Humm...

 

seems like you pretty much narrowed it down...arent't computers lovely? A LOT of trial & errors, lot of research...
