Final clarification regarding Conroe MB support

[freecableguy]

Progress....

[freecableguy]

FCG, can you confirm that P5WDG2-WS would be not compatible with Merom although I make a bios update ?

Thanks

Merom is not the right socket for that board....

[georgesod]

Progress....

Ok i bet you can do more. Let's see 3000 for start

[proth]

EDIT: Let me change one thing that I said in the first post. The Intel Bad Axe board is the only 975X board that has a compatable buck controller.

-FCG

You might want to add "IMO" to your statements....

Correction #1, but who's counting

@ FCG!!

On another forum this guy has some questions, Im just going to post a quote of what he says. This is simply a quote from his post. Maybe you can explain to him in detail.

Ok, where is this guy getting his enlightenment from?

The whole VRM is as much a rumor as everything else. Can you provide me a link to Intel saying that their is a VRM problem? If you think about it logically, you would realize that Conroe uses more than 1.1V, which is the lowest that the P5WD2-E offers. Also, desktop motherboard that support the Core Duo have the 975X, the same one that is on the Conroe. If they support Core Duo, they support Conroe. Also, ASUS did not include its famous 8-phase voltage regulator, but rather a weaker 4-phase one. No won really understood why, but it seems to fit Conroe specs.

FCG... what revision board is that? is that your modded 302?

[Rovtar]

Further clarification:

Intel D975XBX (revision 304 and greater) motherboard with latest BIOS ("0618"/1009) supports Conroe:



Timings at stock 533FSB (4-4-4-12) with 1.9v VDDR2. No optimizations. Actual vcore is about 1.175v. So far I have gotten a little lower to 19.028 sec SPI 1M.

is this mobo comp. with crossfire/sli?

[jmax_oc]

Merom is not the right socket for that board....

I would say conroe
Is the Work Station compliant with conroe .

[FischOderAal]

is this mobo comp. with crossfire/sli?

CF, no SLI support

[Waus-mod]

fcg... how does the board clock in youre expirience? like what brand can you compare it?

[jmax_oc]

Read his first post, no.

I read his post but I found every where a different version : yes for the WS motherboard

[Salvador]

I need one of those boards, and a Conroe, if someone want's to sell it and ship to Norway to me :P

[WildEye]

Salvador,

Checkout Sneaky's thread about the badaxe groupbuy.

I'm on the list. Maybe we can get up to 40

[Salvador]

Yeah, but I wont bother to buy the board unless I get a Conroe

[vengance_01]

I was like number 4 hehe. I be using a nice 805 for the time being.

[Sneaky]

check out this thread for anyone interested in a conroe supporting mobo:

i will ship worldwide as long as the buyer pays for shipping

Nice, u also got a Conroe to go to that, that you'll ship aswell? hehe

Is it very odd that people is a little bit frustrated..?

@ FCG: What mobo do you use now?

Does it clock good?

That guy doesn't have a clue.

VRM = Voltage Regulator Module.
VRD = Voltage Regulator-Down.

VRD 10.1 = old specification used for Pentium D. Covers the voltage range from 0.8375 to 1.6000V in 12.5mV steps.
VRD 11 = latest (yet unpublished) specification which prescribes use of VRM capable of chagning voltages in 6.25mV steps -- required for Conroe. It is not about the range, just about the step size.

So with VRD 11, what will be the total Vcore range from lowest to highest ?
Is it the same as older VRD 10.1 ?

OK.. maybe he doesn't "have a clue"..
Could you explain why changing the regulator "step" from 12.5mV to 6.25mV makes a Conroe work in a given MB/Bios combo.. and not work when using VDR 10.1?
For those of us that only care about maximum clock/performance we want the VCore to stay *stable* at the highest VCore the MB/CPU can handle (with a given cooling solution).
That's why the "guru's" do voltmods on the board to "overrule" such "functionality" (regulate VCore up/down during load/idle)....

[Rovtar]

This mobo is ing expensive

[EmineM]

Can one use the Merom on the Aopen i975Xa-YDG board?

[cirthix]

Can one use the Merom on the Aopen i975Xa-YDG board?

1: not the place to ask this question
2: yes, use the latest bios

So then if it's possible to mod a 10.1 to use 6.25mV it would work?
