Phenom doesn't support DDR2-1066?

[KTE]

The admin at MSI HQ forum says Phenom does not support DDR2-1066 and everyone is wrong who says it does.

You can read my thread here: http://forum.msi.com.tw/index.php?topic=112788.40

It's pretty fuinny and stupid at times. Bas (admin) pointed out something I overlooked.

What is this: http://www.amd.com/us-en/Processors/...E15334,00.html

"Upto 12.8GB/s @ DDR2-800"

"Supports PC2-8500 (DDR2-1066*); PC2-6400 (DDR2-800), PC2-5300 (DDR2-667), PC2-4200 (DDR2-533) or PC2-3200 (DDR2-400) SDRAM unbuffered DIMMs
*Pending JDEC approval and release of DDR2-1066 specification"

So only SPD programmed DDR2-1066 is supported and not until JEDEC spec is finalized?

I'm not in the best of moods honestly. Someone clarify this for me before I end up selling my chip or my board or both.

It was my understanding that AM3 chipsets (like the AMD RS780) will have 'official' DDR2 1066MHz support due to the JEDEC standard. It will also support DDR3 1333MHz.

KTE as far as i know there is no JDEC standard for 1066

http://de.wikipedia.org/wiki/DDR-SDRAM

so it is normal that you run the 1066 on SPD settings. To my opinion that is exactly the same on any nvidia and intel chipset.

now you are stating that you are unable to get it running on MSI but you can on dfi/gigabyte?

[KTE]

I'm aware that JEDEC hasn't even finalized/approved 1066 DDR2 spec yet.
RD 790 chipset supports DDR2-1066 perfectly.
MSI Platinum cannot run 1:2.66 divider which gives DDR2-1066 at stock HT ref for Phenom.
Gigabyte boards run 1:2.66 divider fine with RAM that is not SPD DDR2-1066 prigrammed, so you get DDR2-1066 at stock.

Crucail Ballistix Tracer that I have are not SPD programmed 1066 but EPP 1066 (attached). Like most people.

According to MSI HQ admin Phenom does not support PC2-1066 RAM (stock HT ref) which is not JEDEC approved/finalized. Which means no DDR2-1066 available yet is supported.

How can this be if I've seen people run DDR2-1066?

[LIKMARK]

I would understand the info as this: The MSI board don't support 1066mhz...

[destsh]

The gigabyte board does, I ran @ 1066 with 2 sticks of 8500 ballistixs ... till I added 2 more and it stepped down to 800

KTE is right. There is no JDEC standard for 1066 PC-8500. However, you will notice that Phenom and 790FX support the EPP (Enhanced Performance profile).

If you have your DRAM sticks in the correct slots on your motherboard for *Unganged Dual Channel Mode and set your bios to Optimal, it will default to 1066 Mhz SPD. My Gigabyte MA790FX-DS5 does. Since Bios F2. I will post a screen later if you request.

*see my thread on Gigabyte MA790FX-DS5 about the dual channel slots. Gigabyte's mobo manual is incorrect, you have to have the DIMM sticks in both the same color slots. not 1 orange, 1 yellow. but both Orange or Both yellow. The bios would always default to 667 Mhz SPD on auto, UNTIL I did this.

EDIT: Here is a youtube video of me doing in LIVE! (yeah baby)

Then can you http://www.xtremesystems.org/forums/...&postcount=420

And you too dehx

Please

Officially the CPU supports the 1066 mode with the true-1066SPD DIMMs (and at 1.8V +-100mV). the MSI board works fine @1066 if a 1066SPD module is used.

there will be a BIOS fix to allow 800SPD modules to be manually adjusted to 1066Memclk mode. this is not guaranteed to work and usually requires using higher than spec Memory voltage. So its an Overclocking option.

there are some 800SPD / 1066rated @ 1.8V DIMMs out there though

and yes, certain board makers have the manual 1066 mode working already.

[KTE]

Thank you for the feedback guys.. and macci.

It's very valuable and time saving to have you around.. or we'd beat each other to death over these issues as noo-one knows them factually. All is clear now.

1066 =1E or something else?

[destsh]

Done ... posted

[KTE]

LOL! Excellent work guys, thank you.

[Cooper]

MSI Platinum does not boot up with RAM @ 1066 even if it's raterd at that speed

[KTE]

Yep. Check the MSI link above out. They banned me for proving them wrong.

[Russ_64]

KTE - Mate, I can't see that they banned you.

I understand your frustration having bought the Plat MB and DDR2-1066 RAM but it's early days and these technicalities will cause head-aches. Hang in there, once people start using Phenom (there are not that many with MSI yet - mine is still in the box) there are talented BIOS tweakers around like SideEffect who may help us out one day.

[KTE]

The guy nicked Bas (admin) there sent me a PM full of personal abuse out of the blue when we proved him wrong here in this thread and after he abused posters here he banned me. First time I've been banned but I don't care becaue he's a "Chief moron" as he perfectly recognized himself.

I was trying to help other users like here because I'm more familar with how Phenom runs on this board and can explain and test rigorously. So much for "user to user" forum.

I'm sure with time there will be better developments. The board is very good otherwise, the design and layout is fab.

[dehx]

Hey, Gigabyte MA790FX boards are fab too honey bunch.

[KTE]

dehx: did you just call me "honey bunch" ? .... .....

If so I hope you're a woman... sincerely.

KTE - I feel your pain.

I got the MSI for the 4PCIE slots and teh 1066. I clearly saw online that 1066 was an avilalbe mem divider. Something that wasn't present in the nv590. When I popped in my memory and didn't see the 1066, I was a bit frustrated.

Hopefully they will get this fixed w/ a new bios.

The divider is there. It's just not working - can't boot no matter what the mem settings are. Though I've been using an Opty and on Gigabyte DS5 board with F1 BIOS 1066 divider was not available at all. Maybe opterons do not support 1066

everyone listen very closely.

If you are unable to run at 1066 on your 790FX chipset, WITH a phenom processor, try putting your DIMM sticks in the same color slots. this seems to be affecting more boards and I am finding out.

Try this, then tell me if it works or not.

I am making a list of motherboards that this is affecting.

I am not going to hate on MSI for this one mod and crikey, that is lame. Unfortunately, that is a user to user forum so you aren't speaking with folks who work for MSI.

[R3d]

specs are below.. memory's only running at 6400
2x2gb crucial kits.. paired modules in the same color slots on my Asus M3A board.. gone into bios and manually set it.. boot into windows.. back to 800.. check the bios.. still set for 1066..
