K10 demo machine in Akiba

[PhilDoc]

I've asked before but didn't get an answer. In this situation, how come the memory controller is running slower that the CPU? 1400mhz MC vs 1900mhz CPU. I thought the MC would be running at the same speed as the CPU.

I think Dave was working on this. He was saying 400 for single power plane and 200 for dual. He was also saying something about a bios change helping this, but it may take a cpu revision. He's the expert and would know. For me I wonder if Phenom would be the same. Ether way, getting them clock for clock would certanly help performance.

if superpi runs like other programs like maya, there was a report done with quads i had it favorited but it wont come up anymore

that the quad has so much room with all those cores that the programs running on the quad basically freaks out and slows down if not stops because it doesnt know how to work with that much room, thats why the quads have worse scores then duals like in rendering and stuff

[kyosen]

Kyosen are you sure that CPU-z is working OK might be just a problem readying.

Not sure...
...I should have checked it by decreasing memory modules, but not yet.

[GenTarkin]

So.....Is that POST screen accurate in stating the cpu is a B1 revision?
Cuz, I know there is a lot of confusion going around about who is testing what revisions in reality. So, Im wondering is this truely the reflection of the B1 performance? ----meaning is this really a B1 or is the board confused and we still dont know...
Just wondering lol

[PhilDoc]

From what I know all reviewer got B1 revisions, which are cripped ~5%, don't know exact percentage. The true shipping revision is suppose to be BA, which is not crippled.

[metro.cl]

Not sure...
...I should have checked it by decreasing memory modules, but not yet.

maybe try a diferent app just to see what happens

[GenTarkin]

wait wait wait....whoa...I did not know that but only a 100mhz difference on a K8 yeilds 10 roughly ten seconds in SuperPI 1M?? @ that low of clock speed
Thats some crazy scaling.....
So, if the K10 scales anything like the few experiences have said...it does...then
The results of a k10 higher clocked should be some quite nice numbers no???

[KTE]

This one is of the B1 revision?

Yep, its B1.

Kyosen: thanks bro. Your pic wasn't showing up to me y'sterday.

FWIW, thats exactly double the single core P4 3400MHz total score there. BUT the memory bandwidth is way lower, although the cache bandwidth is far higher.

Why do the cores read 900MHz bootup frequency and 111.25% oc? Are you sure they were all running at 1900MHz?

[s7e9h3n]

The North-Bridge is running at 1400MHz.
It seems that FSB(=HyperTransport, I think) multiplier is restricted upto x4.

The NB/IMC is running @ 1400mhz and not the rated 1600mhz because the motherboard either doesn't support dual power planes or the feature isn't enabled. If it was, the NB/IMC could run at spec'ed speed.

Why do the cores read 900MHz bootup frequency and 111.25% oc? Are you sure they were all running at 1900MHz?

The program is probably detecting the multiplier for the wrong p-state for the cpu.

[BeardyMan]

Run 3DMark05 instead

SuperPi doesnt like AMD..

Marking your words here.

[Equil|briuM]

Wow, another pointless test.

How about testing it on -

A - A Fresh XP install.

B - FULL compatible hardware in full cooperation with K10.

[tictac]

hei... the NB speed does it equal to LDT speed?

[rfurman24]

Why not just use superpi for linux? As stated before just another worthless test.

[kyosen]

hei... the NB speed does it equal to LDT speed?

No, the NB speed is 1.4GHz and LDT speed is 800MHz = 200MHz x4 in this boards, it looks.

[tictac]

can we overclock nb speed? and if we can does it improve l3 cache or memory performance?

[dinos22]

ah nice
kyosen raiding a joint with his HDD hahah fantastic
you sir are a true geek

[informal]

can we overclock nb speed? and if we can does it improve l3 cache or memory performance?

With Phenom it will be possible,and it will give a new dimension on AMD OCing .Separate PLLs per core will make possible individual core OCing and separate power plane for IMC will make possible the higher freq. for IMC and L3 cache with independent VddNB adjustments.December can't come sooner enough

[erwinz]

go kyosen

[Thesavage]

Remember reading on the old aceshardware that a small oc on the L3 would provide a nice speed bump, not sure if that is true though.

[macci]

tictac,

HT speed can be equal to NB speed w/ HT3 chipsets..

overclocking the NB will result in improved memory performance. Can be overclocked via HT ref. clock or via NB multiplier (which may or may not be locked..).

[KTE]

Lower L3 cache latency is one benefit of that.

[IvanAndreevich]

I can't wait to see AM2+ samples tested in the wild. These crippled mobos / bios / old rev core (which apparently possibly doesn't have L2 working or something along those lines) don't mean much. But this DOES SHOW how far AMD is from actually launching this CPU on the market.

macci
Don't they want to throw some K10 AM2 CPUs your way to put on the autocascade and prove that AMD is still in the game? I think the PR stunt Intel got FUGGER to do for them by breaking WRs with Penryn is kickass.

[GAR]

Super Pi is a cache test, the more cache the faster it will go, it doesnt mean its going to perform less in games, super pi doesnt mean jack.

[tictac]

wow.. thx macci.. that would be great.. so we need to wait for rd790 board featuring ht3. im getting more confused lately with all this new stuff nb speed , l3 cache latency.. ht3 speed.. :p

[BeardyMan]

Super Pi is a cache test, the more cache the faster it will go, it doesnt mean its going to perform less in games, super pi doesnt mean jack.

I can't disagree but,
Superpi 1M is like the 100M sprint men in the athletics , queens sprint.
the ultimate speed test..
