Yonah results on OC!

[WeedJunk]

Anyhow, even if it won't be the best motherboards, for me, it's more important to be able to overclock your cpu until it's still stable and you can use the overclock 24/7...

[lowfat]

Might be able to clockgen higher maybe? hopefully.

[WeedJunk]

Only thing we can do is wait, wait, wait

i had a really nasty dream this night :P i did see an dfi 975x s479 enthousiast board :P

That'll be all those LN2 fumes doing that to your head Waus-mod

this is not over clocked but i thought i would share.
we just had a rep with a asus napa platform laptop and yonah 2ghz.
i ran some super pi tests to compare it againts 840d dual core pc's i tested in the past.

the system has ddr2 533 ram running at 5-5-5-15 nothing optimised
this little laptop out performs 840d with 2gb of ddr2 800 on all 4 tests
but running both cores the bus and ram speed of the yonah limits it's performance (i think) and the 840d is not that far behind on the 2x 8m pi run.

1x 1m pi



this is 10 secounds faster that a 840d with ddr2 800

2 x 1m pi is 5 secounds faster than a 840d which was the same time as a single 1m pi run



1 x 8m pi the 840d took 7m 08S



and 2 x 8m pi the 840d took 7m 23.

[Supertim0r]

I want one

[DaWaN]

30s @ 2ghz
They are very fast, now let the good boards arrive

[wittekakker]

Well, yeah, but that's only one core. I wonder how well it performs in 3d mark then. I hope the FSB isn't going to hold it back that much with high spees.

[leejsmith]

the laptop has intel on board graphics so no point running 3d mark on it.
I hope to have this for a couple of days next week and was planning on running benchmarks on every multi to see how the cpu scaled and perhaps show a nice performance curve.

[Frodin]

Hmm, is the Vcore- reading in CPU-Z correct? Isn't 1,4 a little high for default on 65nm process?

[alexio]

It's wrong. I'll lookup the specs of the Yonah cpu now and put the real vcore in this post.

EDIT: it's 1.3v

[alexio]

I was just looking at the tech docs at intel.com and saw something that I have a bad feeling about. I think Yonah will only have upto 1.5v vcore on any motherboard unless somebody hacks the bios or something.

In the Voltage Identification table the voltage goes up to 1.708v with Dothan and only to 1.5v with Yonah. I'n not sure what this exactly means, but I just hope this won't cap the vcore at 1.5v without mods. I'm not sure it's a real problem with normal cooling because it's 65nm and even Dothans don't do much more at above 1.6v vcore with normal cooling.

[Bogi]

@ leejsmith
thx for your test

[leejsmith]

It's possible cpu-z does not know how to read the vcore correctly
when idle the cpu drops down to 6x 166 and 1v.

[lawrywild]

hey Lee,

reckon you'll get your mits on a Aopen board before most people? if you do, I want to see some results

[leejsmith]

Hi Mate,
still trying and the asus rep knows some one at aopen too said he might be able to help.
i think the yonah could not be the best system for me i need to compare it againts the 920d i have @ 4200 for xvid encoding using autogk. with the high fsb of 300 and ddr2 @ 800 4-3-3-4 it will encode an hour of mpeg2 in 35mins.
When i get the laptop back next week i will do some more testing and see how fast it encodes the same file.

I hope the FSB isn't going to hold it back that much with high spees.

You won't have problems with FSB I think because with a i975 chipset you'll be touching the 200mhz FSB easily

Also Alexio are you scared for a soldering iron That'll fix every vcore issue

2xsuper pi on the Yonah will need more time than 1x, because of the smart cache..

Do you know abut CRCW PRAM? Yes it will, but not that much.

[crotale]

the laptop has intel on board graphics so no point running 3d mark on it.

Can you try the CPU test in 3DMark06?

[leejsmith]

@crotale sure i will give it a try


@Kjaks what do you mean 2 x pi will need more than 1x ?

[cirthix]

@crotale sure i will give it a try


@Kjaks what do you mean 2 x pi will need more than 1x ?

what he means is that 2x pi will be slower on the dc yonah than a single pi on a single core yonah because the cores share cashe.

[zbogorgon]

any info on that 3dmark06 cpu score?

[leejsmith]

not until i get the laptop back from the asus rep should be monday

any info on that 3dmark06 cpu score?
