there isnt an overclocking protection..

THG is stupid and there is a problem with the asus board about the throttle

dude check the front page ;)

there IS an overclocking lock, abit, asus, msi , gigabyte and other manufacturers have verified this already! and now even intel indirectly admitted it!

"Intel has done extensive evaluation of our 915G/P and 925X chipset products and have designed them to run robustly at 800FSB. Any use or operation of these chipsets beyond their specifications, including overclocking, has not been evaluated or validated by Intel. If a board provider decides to overclock their platform, they do so at their own risk, since this action will void the warranty for the Intel products. Additionally, from time to time, Intel may choose to implement functionality that helps to ensure that the Intel product experience is not degraded by those who may try to run our products out of spec."

if you still dont believe it read the anandtech article about the overclocking lock ;)

weaponx is already drooling all over his new $300 925x board....

Easy way to bypass the lock - just get a 775 mobo w/ i865PE chipset :D
Thats what I just did, Abit AS8 + 3.2E LGA775.
Did a quickie OC test and it runs SuperPi 1M @4001MHz w/ stock cooler and 1.50V

The point? you get D0 prescott (seems to run cooler than the old prescott), mobo w/ improved power supply and you can still use AGP card and tH3 BH5 RAM instead of silly DDR2 :D

OR just wait for SiS or VIA to make a chipset that doesn't support locks.....

I'll be taking these "locks" with a big grain of salt until some product gets out there and we see some reality.

I mean, Anand said they couldn't pass 248 FSB at any point, with any chip or mulitplier, ES or not, on the Asus board.

But these guys hit 270 FSB no problem on the Abit board (and DDR 772...whoa):

We'll know soon enough ;)

Damn macci...that's a sweet find! Nice work, as always...
Curious...do you see any potential in DDR2? I mean, DDR 772 out of plain first-gen Micron sticks...pretty impressive. 350+ FSB potential at 1:1?? Hmm....

you didnt read the xs news i posted :P

sis and via postponed their 775 chipsets to Q3/Q4 !!! :(

nice macci! 4ghz with 1.5v? what cooler? that huge retail hsf?

are there also i875 lga775 mobos coming out, or already available?

so far i have only heard of 865 boards, but there should also be 875 boards...

saaya, yea bone stock cooler :D

omg now we wont see there 'more than likely superb' 775 chipsets anytime soon!! :0

well would still be better than a 250$ overclocking locked intel board or a 300$+ overclocking Unlocked board from asus or abit :/

macci, does this lga 865 board give you better results at the same speed compared to a normal 865 board?
can you reach a higher oc than on a normal 865 board with the same cooling?

4ghz on air? fire up the cascade already! :stick:
:D

BTW, not sure if anyone mentioned it, Via's PT800 and PT880 DO have working PCI/AGP locks. It was proven on xbit labs I think. They used a PCI geiger and showed it.

Not like it matters to me, I'm not going to buy an Intel CPU until they obsolete the Netburst architecture and go back to a more efficient design. The only high numbers that impress me are the ones put out by 3dmark.

Well its official..I have info that states the lock is there..10%.

Abit seem the best at the mo doing better than Asus bypassing the lock. I feel sorry for the smaller guys who don't have the resorces to bypass the lock..their boards will sell a lot less.

Next question i want answered is will EE be fully unlocked and fully overclockable on the 925X? thats is the second tidbit i was given 7 weeks ago.

This doesn't sound like a likely move by Intel to me. It would be great if it were proven to be true, but I have serious doubts. Intel's penchant has always been for finding new ways to control what we do with the processors...not in permitting us to use the product as we see fit...:rolleyes:

Call me a Doubting Thomas, but I'll have to see a retail unlocked EE before I will believe it...;)

As for reports of the Taiwanese board makers finding ways around the lock, they did the same thing with PAT on the early versions of the i865 chipset...Intel then countered and locked down the chipset totally. Any success that would exist in bypassing the lock would be for naught when Intel revises the chipset in its next stepping to force the issue.

But you'd have to admit that an unlocked EE would finally add "some" justification to the price...

Anyway, let's let the Taiwan engineers do their thing and see if this lock gets cracked.

Has anyone tried clockgen? In reading how the lock works, not sure clockgen will do it really, but I have been curious and since already have a few who tried the buggers, thought I'd ask.

An EE with an open multiplier or say a range to 5 notches above default would get a lot closer to justifying the price in my mind.

$.02

You know, it's not just the lock. Moving the lan off CSA was a mistake too...

Is that a retail chip with 2 Multipliers?
Or some kind of ES?

i got to test the video card next so far on stock every coolling the gpu get 595 and mem gets 798 from 350 gpu and 550 mem..not bad there neither.

Do what I did for mounting my new 3.4 S754.:D

Heres the board I'm useing at the moment, DFI 875P-T.
http://www.dfi.com.tw/Upload/Product...P%20875P-T.jpg
The caps are about 1/8" raised above the hieght of the CPU surface so I had to shave my foam down to make the evap stick out more. Other then that, I stuffed Foam tape around the socket.

Check the picture.

And surprising to me I didn't get any condensation.

what are those large black cubes between the mosfets? i always wondered what they are. a mosfet in a different package?

How far can you go with FSB on that thing?

Jeez, they just announced that thing - how do you have one already?

Do you like the DFI board Opp? :confused:

That is likely my upgrade path, as I want to keep my nice (and expensive) RAM, AGP card, and don't like OC locks. ;)

Funny, never thought I'd own a LANParty board and a Prescott! But seems the best path for now...

Kinda interesting what can be done just on stock air, which begins to make me wonder if things haven't been quietly improving while we haven't been looking at Prescott..

Any 1M score for those stock cooled rigs?

(curious)

Nice board, I need to figuer out a few things though. 1:1 works great, runs my PC4400 solid at 285MHz, no mods.

The NB needs cooling though, the thing gets very hot.

5:4 divider seems to be giving me a problem for high FSB.

Thou doth rock PC, thankye :)

If you get a chance what are the available voltages for this board? They're on PriceWatch for $185 and I might jump on one + a 3.4ghz T cpu. :) Even though it doesn't have CSA, it seems well put together. TY :D

I know it has 3.2V memory, 1.8V AGP, and I don't remember v-core but it has plenty for these D0 chips, up to 1.9V I think.

OPP

Thanks OPP! Now it's between this and the new Abit (also 3.2vdimm), if they can hack PAT :)

He was referring to the DFI board, not the Abit.. so I would assume that the vdimm is good up to 1.6vtt, of course I dont have one so I'm not sure.

I'm hoping the abit is okay as well, it's only $110 or so, but on the 865 chipset :\

Haha true Ao, but it won't be more than a year till laptops will be quite useful for gaming. They do "ok" now, but they are heading to making things very gaming friendly for the gamer on the go!

:)


On the OC 775 side, it seems to me that air (just as a reference point) clocks on P4E's are improving. My thinking is that behind the scenes mfg is improving.
