AOD HTLink information

[keithlm]

Below is a screen print from when I press the HT Link button on the "Diagram" page of the newest AOD.

The HT0 looks good... but HT1, HT2, HT3? 200Mhz? 8Bits? Are these 3 additional links not used or perhaps this is where the Gigabyte DS5 motherboard is screwed up?

(Anyone with another motherboard... do you see the same thing on your HT Link information page? 0 being used and 1-3 not used? OR do your 1-3 look the same as your 0?)

Thanks.

Mine looks similar Keith, this is off of the MSI K9A2.
The numbers are a little higher since I run my HT Ref @ 269

I'm curious as to why my LDT Stop Tristate shows "disabled" on Link 0.

I think I figured out the problem with the DS5 though... IT SUCKS!! :horse:

Sorry, couldn't resist... ;)
Nice find though, I'll have to dig a little deeper myself...

Thanks for the reply!

LDT Stop Tristate:

Yours is DISABLED. Mine is enabled... on the F6 bios. I just reverted back to the F5 bios... because it was more stable... and it is disabled on that bios....

For F6 I must run GANGED, AUTO VOLTAGES, and NO TWEAKS; and 1.8Ghz on the NB/HT. (Or things are VERY unstable.)

For F5 I can run use defaults for everything except 1.8Ghz for the NB/HT and all is well. (un-ganged and tweaks on doesn't really affect the stability.)


Yes... I will ditch this MOBO as soon as I can get a 790FX/SB750. I was thinking about DFI... but actually the Biostar looks really good.

YOU KNOW.... it is SAD.. because the DS5 is fairly well BUILT. But of course if it doesn't WORK... it doesn't matter how well they made it.

Phenom is built on a Barcelona design with a total of 4 HT links for MP server systems. On Opteron 1*** and Phenom, three of the links is disabled. :)

I wonder...

SB750...

"magic"...

3 unused HT links....

Could that be their "secret"?????

Maybe they originally disabled them because they figured that they didn't need them... at least at stock... and then later discovered that actually using them allows for a better overclock... so now they've re-enabled them???? (Or at least are now using them in some other manner....)

[Daveburt714]

You guys have got me curious now... I'm going to watch it while the system is loaded (Wprime sounds good) and see if anything changes...

Lol. That's pretty far fetched :D

One link for communicating with chipset, and three links for communicating with other processors on MP systems, Opteron 8***, or one link for communicating with the other cpu on DP systems, Opteron 2***. Hence the price difference too :) Can't see what difference the HT links should make for oc'ing :)

I know... it was a stretch.

But you never know... it is "magic"....

[Daveburt714]

I'm buzzed again guys, so I should probably just shuttup, but you know how that goes... :rolleyes:

Anyway, I tested it with that page open under load and nothing changed, although I did get a pretty good WPrime score (13.188 Seconds)...

Here's a link with a little info on the SB750 that I found tonight (posted in another thread).

Sounds like it's all starting to make a little more sense... Looks like Mobo manufactures will have to get thier stuff together though...

Hmmm, maybe to enhance signal strength:confused:

*disclaimer, Ive no clue about this all though, just trying to understand/help understanding.

I mean, using a single HT-link because it's one socket makes sense, but AOD is mainly aimed for 7 series chipset. But there's no multi socket board around using that chipset. So why would they include that information?

DP/MP socket G34 is supposed to come with AMD chipsets RD/RS890 or something (in a future far far away...)

Love your avatars btw keitlm and daveburt714 :D

Edit:

Just to spin it further, maybe AMD has rewired all the Ht links to resemble Intels QPI, using all the HT links to communicate with the chipset with lower latencies :shocked::fact:

[SocketMan]

Don't forget that it's all linked thru HT:
CPU-NB
NB-SB
NB-PCIe
the tri-state is disabled by default (usually)
unless you've got a gigacry :rofl:
sorry could not resist, they do make good PS I have to say:yepp:
I've posted the slide explaining the SB750 magic in the AOD
2.1 is out thread

You can blame Daveburt.

I was sitting there last night... seeing his zombie girl with pancakes... and it made me hungry. But zombies don't eat pancakes... so I found a different one.
