go yonah or is conroe worth the wait

[leejsmith]

yonah is looking very promising but boards are limited and from past desktop mobile platforms the aopen boards have been week.
granted the i975x boards should be good but is this going to be a one chip yonah board only or will it support future chips.

I have a p5wd2-e at work and have sold most of my dothan stuff ready.
bought have some ddr2 fat body d9 and x800gt02 which is good for both systems.
i want it for video editing , xvid compression , dvd authoring tv stuff recorded from my sagetv box.
maybe the odd game but i have an xbox360 which is filling my games needs very nicely.


will conroe work in the p5wd2-e should i stick with that and a 9x0 dual core until conroe is out or should i get the aopen board and a yonah and stick with that.

it's possible both the p5wd2-e and aopen boards will be of no use on another year anyway so either path would be ok .

what do you think ?

[Waus-mod]

Buy a aopen 975x and yonah... when conroe is out sell it and enjoy conroe!

[onewingedangel]

the problem with that would be that yonah isn't socket 775. Compatability of current socket775 i975 boards and conroe is not yet confirmed either.

[leejsmith]

so you dont think the p5wd2-e will be ok with conroe ?

i guess thats the key point in my choice is will the p5wd2-e support conroe.

if not then go with yonah and stick with that for 1-2 years i think.

yonah will require the new VRM so we need new revision boards to support it )

[leejsmith]

do you mean conroe will need a new vrm to work on the p5wd2-e ?
which from my testing droops very bad.

i'm pretty sure,conroe will not be supported by any of today mobos ;)

well after playing with the p5wd2-e this weekend i think the very bad vcore droop it has makes it a bad choice anyway.

playing with a 920d the fsb was no problem at 320 x 14 4480 vcore was set to 1.45v in the bios and @ idle it would show 1.50v and running 2 x prime 95 load it dropped to 1.38v
i have the northbridge water cooled with a dangerden zchipset block and cpu cooled with a storm g4. cpu temps never went over 51C with system at 29C
ram was to at 800mhz ddr2 4-3-3-4 2.2V fatbody d9's
i tested the ram with memtest and after 30 mins of test #5 everything looked ok.
tested in windows no problem single pi 1m -8m and dual pi 1m-8m
cpu stability test for 30 mins.
ran 3d mark 2005 and it failed cpu test #2
then it started to act strange and pi would fail unless i set the affinity to a single core.
then that didnt matter.
so i decided to try prime 95 using the small test to test cpu only.
at my original settings of 320 x 14 1.4 vcore it failed prime 95 once i started the 2nd instance.
i increased the vcore to 1.465 but this didnt help. so to get it 2 x prime 95 stable i had to drop fsb to 310 but at the same time could drop the vcore to 1.42. this would run 2 x prime 95 no problems for 30 mins but no super pi very strange

i think the problem is with the vcore droop but also something else is getting warm and unstable over time.

i am going to go back to a p5wd2-premium to see how that works but unless the aopen i975 board sucks big time i will go yonah as soon as i can get the aopen.

i will post some picks later.

unlikely

take a look at this.

what was told OFICIALLY is that yonah cpus WILL need a new VRM...
the voltages the require are lower and the need to be changed in smaller steps...

lol. I swear the not wasn't there before :confused:

I can't read..

Yonah might be a short transition, these mb will be availlable in March I hope, then next mobile chip will be out in June? or July?

hopefully Merom will use the same S479 pin layout as Yonah.

[cirthix]

hopefully Merom will use the same S479 pin layout as Yonah.
Socket 480 i beleive, with 478 pins and 479 holes.

I've heard that there's a good chance for that :).

I'll be switching to yonah then merom most probably.

I guess these 2 articals on xbit answer my questions on motherboard lifespan.

975x mobo's need new vrm's for conroe so the p5wd2-e i have wont work with conroe/

http://www.xbitlabs.com/news/cpu/display/20051019183430.html

memron to be pin compatible with yonah.

so the aopen board could be good for a while with yonah then upgrade to memron as long as that wont need updated vrm's too.

[flakpyro]

Anyone heard any more news about if memron is backwards compatable with Yonah stuff? I am going to have to choose between getting Yonah now, selling it and getting Conroe or just waiting for Conroe.

intel is in the chipset business too.
i have yet to see them release a chip that didn't require puchasing a chipset with it ;)
