AMD Zambezi news, info, fans !

[Smartidiot89]

I've switched CPU's many times in my own system and not switching TIM For example when my short patience runs out as I can't find my tube I just don't give a damn. Sure I gain like 3-4 degree's C when I use new TIM but it's not the end of the world.

Fixed

Yepp again, my tube of my favorite TIM disappeared so I didn't put on any new as i changed from a Corsair H50 to H70 Temps are still alot better than with H50 :P

In case ou haven't seen yet,
More info on Desktop Bulldoser...

AM3+-confirmed-support (this was obvious...)
Insteresting part - "Finally, we’ll share some interesting tidbits from our conversation that you may or may not know. The Bulldozer architecture (complete with eight cores) is being designed to be highly multithread-capable. The pinouts on AM3 and AM3+ are different. However, AM3+ CPUs will physically fit in an AM3 socket."

ATI-Forums-Pics-of-Bulldozer Looks like the pins will fit AM3 after all... that is, if this is what production chips will have.

[FlanK3r]

yes, but u must to have electricaly activ pin contacts to the motherboard at AM3 and 13MB flash memory. Zambezi has 940 pins (u can calculate it from screen ). AM3 socket has 941, but not all contacts are activated standardly (Thuban and AM3 Denebs has 938 pins)

That is true, but at least this might help settle the aspect of it physically fitting Still can't wait till launch and can try one out on the CHIV....

But I think, we will see some diference between AM3+ 990 and "hacked" AM3+890

I believe so too. I will be getting 990 series board when they come out, since I can't resist..

[FlanK3r]

hehe, Im too, looks at Crosshair V Formula or so :-). Hope, I will be lucky as with my x6 1090T :-D

I believe that too!
But I'm also curious to see the difference between:
new revision am3+ 770/ 870 and hacked am3/890fx!

I cant think an entry level (50€) mainboard could be better of a crosshair IV only for different socket...

[Smartidiot89]

But I think, we will see some diference between AM3+ 990 and "hacked" AM3+890

Main difference will most likely be that most(if not ALL) AM3-motherboards with "hacked" support as you call it won't be able to utilize Turbo Core 2.0 in Bulldozer.

and second maybe full HT link (Zambezi will be think min with 2600 or 3200)

[BeepBeep2]

Since it's running HT 3.1 the max you will see is 2600, I doubt we will get that high though. Current AM3 boards can pretty much all do 2800+

I recall chew* saying max stable and highest you'll see gains is like 2.7ghz.

and from what I've read HT3.0 top speed is 2.6ghz so maybe that will be stock for bulldozer.

and maybe we can Over clocked 3.3-3.5ghz

[stangracin3]

iirc the first to do 3ghz was actually an athlon II

Trust me we can already do that
Here's my 965/890GX doing 2.9 in 3D
I just had my M4A89TD at 3.38 Ghz, I went for 3.4 but CPUNB is very unstable at that point and I locked up.

iirc the first to do 3ghz was actually an athlon II

I can not recall if I hit 3 Ghz on my 965 or not, if I did it wasn't stable due to CPUNB instability...

Here's 30 min P95 Blend - I'm not gonna stay up for 3 hours so test ends here

Yes thats 79 processes, install couldn't get dirtier

In addition to supporting previous HyperTransport interfaces, AMD Family 15h processors support a newer version of the HyperTransport standard: HyperTransport3. HyperTransport3 increases the aggregate link bandwidth to a maximum of 25.6 Gbyte/s (16-bit link). HyperTransport3 also adds HyperTransport Retry

So...If I understand correct, this is up to 3200 MHz...

[SkullCracka]

not sure if this is old news but first i have seen for am3+ with 880/850 chipset. http://www.newegg.com/Product/Produc...490&Tpk=am3%2b

I guess you are right...

HT 3.0 is what is on current boards, HT 3.1 is what you are talking about...but I can't remember if Zambezi will use 3.1 or not.
I'm confident I can get 3200-3400 out of my board easily, my run at 3100 I was running 1.25v when stock is 1.20, it was just a set and run, didnt test for lowest volt. Remember, HT must be equal or slower to uncore speed, so unless AMD ships a 3000+ uncore speed I think we will all be very safe.

As far as the Turbo -
ASUS Beta BIOS 3012's had two Turbo options I have a feeling "Turbo 2.0" could also be implimented on these boards

[Manicdan]

which is uncore? HT or NB?

While my 555BE wouldn't, this Athlon II X2 250u (1.6GHz) I had would let me boot with a HT speed higher than my CPU-NB, on a Gigabyte 890GX-UD3H (like F3 BIOS, long time ago). I've done it from Windows on that config too, using CPU-Tweaker and AOD. That was my first new system from S939, and I was learning everything fresh, so I made a note of the fact that with that 250u @ 2.9GHz, the CPU-NB at 2175MHz and the HT @ 2355MHz had better memory performance than 1:1.

As for 'Dozer talk... I'm bummed that my ASRock 890FX Deluxe3 won't support AM3+ At least, it's highly highly unlikely it will, considering they released Deluxe3 with black socket and marketed as AM3+ :\ Then again, black socket doesn't mean everything I guess. MSI's 890FXA-GD65 is white and the board is silkscreened with "AM3+ Support" above the NB heatsink.

[FlanK3r]

for me is AM3+ socket now the next future. Need max performance, not compromise...Remember, AMD had long,long, long compatibility. They can not be still on one socket. ANd still we have part compatibility (AM3 CPU to the AM3+ socket). Look at Intel. Last years again and again new LGA ...

[XRL8]

Flanker, AM3+ IS in 99% percent the same socket as AM3.They messed around with one pin to have less headache support wise.It uses the same architecture,same HT topology, same chipsets,and is compatible with am3 cpus.So its the same damn thing.Theres no new breakthrough technology behind it.
Maybe youre talking about 9xx chipsets and not am3+ socket alone.However, it looks like at least northbridge will be exactly the same, we will see about southbridge.
In essence, with 90% probability, there wont be any difference performance wise if you plug the chip to crosshair IV or a 990FX board.

Define stable?

What you consider stable and what AMD is diff.

Add 4 way gpu to the mix and 3d benches will crash at specced voltage.

Last but not least they're HT bus is more than ample and does not show massive gains except in IGP clocking due to the fact that the HT bus is not saturated even in heavy 4 way crossfire.

Ithink, we will see some diferents. UEFI bios. No, seriously, I dont know how about Turbo core 2.0 and Cross IV and how about some OC potential against 990FX+AM3+. We mus waiting at Computex or E3 (hope for launch this days)
