Asus P5W64 Pro 470FSB out of the box

[goreblast]

Question for you guys already runnig this board. Can you run crossfire graphics (both at x8 I know) in slots 2 and 4? I have an Areca 1230 on the way which runs at x8 and I wanna use it and crossfire. The only way it will work is if I use the 8,8,4,8 config with the Areca in slot 1, the master x1900 in slot 2, the slave x1900 in slot 4 and my Xfi in the bottom PCI slot.

Or will I have to go to one graphics card? I which case is it best to go for a Nvidia 7950x2 ?

thanks This is my future mobo

mine too

there are two different configs for pcies, 16-0-4-0 or 8-8-4-8, so CF will work with 8x-8x in 1-2, 1-4, 2-4 combinatios, so your config will work.

What he said

Assuming you're using double-slot graphics cards then your choices are either:

Areca (8x), Master (8x), Empty (blocked), Slave (8x)

or

Master (8x), Empty (blocked), Areca (4x), Slave (8x)

Areca seem to think there would be negligible performance difference between using a 8x or a 4x slot - and it will work in the 4x speed slot. Using the Areca in slot 1 will leave very little room between your two graphics cards (assuming they're double slot), something to bear in mind.

little more tweaking, still both cores on

How high can you go with 1:1 divider?

My board maxes out at 495FSB with 1:1 divider and 4-4-3-4-26 settings.
The MCH is watercooled and slightly overvolted, 1.86V.



Crappy 975X made in Costa Rica
All of the previous 975X chips have been made in Malaysia.

How can you tell where its made?

How can you tell where its made?

They have batch codes just like cpu´s.
Code starting with:

L = Malaysia
3 = Costa Rica
7 = Philippines
5 = China
Q = Malaysia
etc.

for spi 1m i was at 510, but I am quite sure that rams were the problem, at the moment i don't have rams that would be able to follow

but i put cpu on SS, help a lot with max fsb, and i was able to validate at 543

respect,zbogorgon!that was with vmod or without?

[Exedy]

543fsb on 975X, wow now this is freaking...

[Dumo]

Here we go...The fun part with high Mhz and high FSB (with this board)..

Awesome run there Stilt and Zbogorgon

Do all the memory dividers work on this board ? Im thinking of replacing my DH with it.

[techstyled]

I haven't even played with my P5WDG2 WS yet! It's still in the freakin' box.

More stuff to buy...

Is this board lookin _that_ much better than the rest of 'em? What am I saying. Let me rephrase, is this board lookin' to be the best of 'em?

EDIT: Plz excuse the noob for not reading the whole thread before he posts (me). Ordering board now, thanks all for posting results.

[Dumo]

Yes, performance wise.

Except Vcore OVP @ >1.7V.

[Supertim0r]

we need an ovp bypass mod
getting this board this week

[sierra_bound]

My CPU feels rock solid on this board at 4GHz and air-cooled.

Has to be really really good 6800 to run >4.8Ghz with 1.7V

Nice one there Sierra. What week?

[sierra_bound]

Thanks. It's an L623. Still on air.

The main ratios (4:5 & 2:3) work, but not as well as on the P5B Dlx.

[techstyled]

May I ask what memory you are running there sierra?

[sierra_bound]

I'm using Corsair 6400C3. Not many memory kits will do DDR2-1212 @ 4-4-3.



This was on the P5B Dlx

Hi Sierra. What voltage did you set in the bios to acheive this result? I've installed this board and am slowly working my way up to around 4ghz if possible, but I don't want to apply unnecessary voltage sine this board overvolts a good bit as it is. Thanks and excellent results as always.

[zbogorgon]

Yes, performance wise.

Except Vcore OVP @ >1.7V.

dumo, have you done vcore mod, can you post a pics ?

[catscit]

sierra: any idea what's holding you back with the x6800?
365 isn't that great fsb?

You have to register at the following forum (OPB's) but it's worth it...
