REGARDING AMD AM3 CPU's and RAM SPEEDS ???

[scjet]

 This is more conversational, and probably more against ALL the Memory-manufacturing companies who are "still" so obviously biased towards Intel-based (P55,...) memory contorllers. In fact, we all know they "tweak" their memory crap for Intel....

 In fact, most of theses manufactures obviously "LIE" about any of their DDR3's,  ...,  being "AMD ready" -huh?
-ya right !

Maybe AMD should do what they did (to a Memory-chip maker) when they decided it is time to BUY a Video-chip maker, namely "buy/own" ATI.

In other words, I wish AMD would do the same and buy a a mempry-chip maker, or better yet, design/make their own DDR3/4/5/.... Memory modules
 Then we would NOT have this problem, (Lieing memory chip-makers and their products) EVER AGAIN !!!!!!!!!!!!!!!!

 If nuthin' else it would scare the crap outta these mem-chip makers, who OBVIOUSLY forgotten about how to build memoty DIMM's properly.
 (that was a pun BTW, get it ?  Memory and "forgetting" ? )

 

[scjet]

 And, the reason I am saying this is becuase I also own a:

MB: GA-890FXA-UD5 (Hardware Revision 2.0), yes with latest useless BIOS (F5)
CPU: Phenom II 1090T Black Edition  -and this CPU Rocks ! -I'm very happy 
Memory: 2-Kits of Patriot Viper II Sector 5 (2 x 4GB per Kit) -8 Gig Kit, "PVV38G1600LLK-DDR3-1600Mhz"
(all 4 Banks are filled for a total of 16 Gigs)

 Anwyay, what a waste of $%#!!!@$ money on Patriot ram, I cannot even get that Ram to clock at 1333, in fact,
it is "locked" at 1066 MHz. wow, I paid for DDR3-1600MHz Ram that can only run at 1066MHz ??

I have checked dozens of OC'ing techniques and all to no avail.

I am definitely NOT pleased with AMD memory contollers or this Patriot memory.
 

 AMD should have solved this Memory-contoller issue a long time ago _ I blame AMD
 why?, becuase in the end its the "coach" who has to burden blame and not pass it off to his players' !!!

 Anway, Hey Gigabyte and AMD, would you people mind getting all this fixed soon ?

Thankyou.

Rick.

Don't hold your breath.

AMD decided to set the Memory Controllers on the AM3 for 1333 MHz or slower (depending on CPU and motherboard) at the design stage because they noticed issues with RAM running above that speed. Only hope is that the new AM3+ Processors, when they come along, will have this particular issue sorted out, but I'm not convinced that they will.

[scjet]

Don't hold your breath.

 I was hoping not to hear that, but ya, u're right -> @absic  "...don't hold breath...".  

 The 1090T is the best bang-for-buck hands down, I know, 'cause I own Both types, and I need to run Adobe Premiere Pro CS5-64bit, for 1080P video editing/encoding.  and ya,  So you might think, well then, what 'da heck is my problem ?  
 I got none,
except, why should we "The CONSUMER" pay for memory that can't even run at it's rated speed,....

 It's just a shame to make this AMD 6-Core "Ferrari" race on country roads with potholes <-like these MEMORY issues are !!!!

 But this is an extremely important issue for amd to deal with (U would think eh ?!).  And, as long as Intel is top-dog then Intel will "pay" memory manufactureers to make Ram work on their controllers better than on AMD memory-controllers -like DUH !!!

 Like I said, I'm sry for going politically/conversational on this issue, but AMD will have to do "1" of 2 things.
Either they work, more tightly with mem-makers along the AMD mem-controller issues,...
Or,
 AMD designs/builds/ and makes Mem modules for us.

 I actually hope for the latter, 'cause then that will END the final "IBM/Intel/...PC" stronghold on the "x86" architecture-based PC's ....

 And, lets face it, Its a Home-"Server"-based world now, and NOT just a "Windows-only-subservient" client-based PC world.

Cheers,
Rick.

 So do any of the AMD Guru guys/gals here have a "GOOD" DDR3/memory recommendation for me, other than trying to call the CEO of AMD and/or Gigabyte ?  

It's For this setup:

MB: GA-890FXA-UD5 (Hardware Revision 2.0), yes with latest BIOS (F5)
CPU: Phenom II 1090T Black Edition  (-and this CPU Rocks ! -I'm very happy)
(Right now, I have this crap): Memory: 2-Kits of Patriot Viper II Sector 5 (2 x 4GB per Kit) -8 Gig Kit, "PVV38G1600LLK-DDR3-1600Mhz"
(all 4 Banks are filled for a total of 16 Gigs) trouble is -it only runs at 1066 MHz ?

 Anyway, I will NEED to fill ALL 4 DDR3-memory banks, for the maximum of 16-Gigs.

 Should I go for this ? :

( this is according to Kingston ram recommendations for the GA-890FXA-UD5 MB, but, I mean who can you trust right ?)



Any suggestions at all, will of course be greatly apreeciated.
Thanks.
Rick.

Click on memory support list and you'll know what will run for sure. Mind you, most RAM out there should run on your board fine. I mean, I have OCZ Intel XMP DDR3 sticks running in an AMD build. Overclocked, actually.

Now that I thought about it - I'm not sure about Thuban but, at least early on, the max speed for 4 sticks of RAM was 1066Mhz for AM3. If it still holds true then it'd be normal for your RAM to clock down.

 thanks for the reply "byetheway_r"
  I'm deciding to go for the "stable"-recommended Kingston DDR3's, 'cause I'm filling all banks. But, this crap better work at atleat 1333 MHz !!!?

[scjet]

 Sadly, I actually followed Gigabyte's so-called OVL Memory list, which is why I bought those crappy Patriot Ram in the 1st place.
 Gigabyte, is unfortuantely, no better than all the other "Lieing" MB maker's as far as memory compatability for "AMD"-based MB's go.

and SHAME on Gigabyte for this !!! yep, that's all I can say.

Personally I think you have been going about this in the wrong way. I would have used the Crucial or Corsair websites and found what memory they guarranteed to work with the motherboard and then if there is any problem you have more recourse.

This is actually making it even more likely that there's a bios caused limit for 4 slots filled. Try taking one or 2 sticks out and see if it'll be possible to run it at it's rated spec. You may need to set it in bios but it should be able to run at 1600Mhz.

I'll agree that all 3 - RAM, MB and CPU makers should be up front about these things but that's just how it is in this world. You have to do your own research before buying things or be prepared to have problems later on.

[Dark Mantis]

I do agree that there is a lot of underhanded work going on especially from AMD regarding the capability of their chips to handle speeds in excess of 1333. Even now they do not make it clear to prospective purchasers.

[scjet]

 Thanks for the tips, and ya, I guess now I am not going buying this:
http://www.ec.kingston.com/ecom/configurator_new/partsinfo.asp?root=us&LinkBack=http://www.kingston.com&ktcpartno=KVR1333D3N9K2/8G

 I have to fill ALL banks (I need the 16 Gigs for Adobe Premiere Pro CS5 64-bit application....)
  even with these Kingston 1333's, I am now afraid with all 4 banks filled it will clock down to 1066, just like my present Patriot Rams.
I guess the best thing is stick with my (4x4Gig-1600Mhz) Patriot Ram

 AMD's am3-memory controller can work at 1333 with 2 sticks, but if you put 4 sticks (ala fill all banks) then it will clock down to 1066 ?
ahh well,  It just doesn't make any sense whatsoever. ?

Hi there,

If you are using 1600MHz RAM then it should default to 1333MHz that's what my 8Gig Corsair Dominator has done and I'm using all 4 slots on my Motherboard. I think you should be able to run at that speed even if using 16 Gig.

Have you tried manually setting the speed to 1333MHz? You may need to up the voltage a bit on the RAM to get it stable but the 1090T CPU should be able to handle all your RAM without a problem.

If not, do what I did and telephone AMD directly and speak to one of their Technical guys. They are very helpful and also you can tell them exactly what you think of AMD's advertising strategy! 

[scjet]

MB: GA-890FXA-UD5 (Hardware Revision 2.0), yes with latest BIOS (F6)
CPU: Phenom II 1090T Black Edition
 Memory: 2-Kits of Patriot Viper II Sector 5 (2 x 4GB per Kit) -8 Gig Kit, "PVV38G1600LLK-DDR3-1600Mhz"
(all 4 Banks are filled for a total of 16 Gigs) trouble is -it only runs at 1066 MHz ?

-ok, I removed DDR3 banks 1/2, and left the 3/4 installed.
I was able to set Mem/clk to 1333MHz,and it booted fine,
 but if  I fill all the banks again, bios complains (hit F1 / Del) and I have to let it Auto-set back to 1066Mhz ?

 I haven't tried turning up the DDR voltage, but in Bios right now it is 1.51 Volts, and my Patriot memory is rated at 1.65V. Is it fairly safe to crank that up to say 1.6 Volts ?

 Anyway, you have 8 Gigs of Ram when all 4 banks are filled on your MB. The reason I ask is becuase I'm wondering if that may be partially my problem, Maxed out memory on this board is 16 Gigs. ?

Thanks again

[absic]

I only have 8Gig of ram 4X2Gig sticks.

Voltage can be cranked quite safely up to 1.64V and even a little higher although you shouldn't need to.

If still having trouble try loosening the timings. My RAM is rated at 8,8,8,24 but is actually running at 9,9,9,27.

Make sure you're running in Unganged Mode
