Asus mobo for 2.0a p4?

Man a lot of this stuff is over my head. I want to buy a p4 2.0a ghz, cause the price would fit perfectly for me (right under $200). Lots of these threads have good overclocking stories with different asus boards, so I'm wondering, which asus board should i buy for this chip. Moreover, how high can i overclock this, with your suggested mobo.

One unrelated question. According to asus, as far as I can digest, their cards support 2100 ddr ram. What about 2700 and 3000? Are they unofficially supported? Sorry for the questions you guys have probably answered plenty of times, but hey, I'm putting my first system together by myself and need guidance, which I'll unleash on the next person in my opinion! Thanks for any info.
 
if the P4B533 series turns out to be as good as it is on paper ... it will be "THE" DDR board to get.

DinoGucci just got one to review and i have one coming.
 
Hey thanks, I'll be waiting for the reviews from you and dino. I've looked a little bit at that card myself... looks promising. Will it support pc2700 and 3000 ram (unofficially)? Thanks
 
I just picked up the Asus P4B533-VM and love it. It uses the 845G chipset, supports:

ASUS P4B533-VM Motherboard for Intel P4 478 Specifications: Processor Socket 478 for FC-PGA2 Pentium® 4 1.4GHz to 2.2GHz+
Chipset: Intel 845G Chipset North, ICH4 South
FSB 533/400 MHz
Memory 2 x DDR DIMM Sockets Max. 2GB unbuffered PC2100 /PC1600 DDR DRAM (PC 2700 Max. to 4 banks only)
Expansion Slots 1 x AGP 4X 3 x PCI
IDE Ports 2 x UltraDMA 100/66/33
Audio Realtek ALC650
Intregrated VGA
Intregrated LAN INTEL PHY
Form Factor: Micro ATX

Hell yea it does! That's what the 3:4 setting does. The only question is how to keep the 3:4 setting alive above 132 fsb. Looks like thugsrook got it but....hehehehehe...he can't enter his bios without losing it, lol. Kudo's to my pal thugs for figuring this out though!! 🙂
 
Sounds very good guys....

badthad wasn't he talking about P4B266 that he bumped up 132 fsb? I'm gonna get a P4B533 definitely, but does anyone have a suggestion on the model? Thanks!
 
I still have not heard if the P4B533 has the same 132 FSB 3:4 mem limitation as the P4B266. I would hold off on buying one until you know FOR SURE. IMHO, the bios/dipswitch hack is "ok" if you already own the board, but not if you are looking to buy a new one. There are plenty of boards that have 3:4 @ any FSB without having to do some hack.
 
If you can wait, wait for the SiS 655 boards to come out, it'll only be a month or so. (It's release date says "Mid-summer")

It's going to be dual channel DDR333. I'm hoping they'll finally include an AGP/PCI lock on their boards, too.
If they would just do that, they would have Intel chipsets beat without it even being arguable. 🙂
 
Or you can just buy an EPOX 4BDA2+ TODAY without the limitations the Asus has. It has:

3:4 mem @ any FSB
Better Vcore range (up to 1.85 Vcore) no wire trick needed
PCI/AGP lock
USB ports that work when overclocked

Erm, the SiS 655 will be more powerful than the Epox.

It'll be dual channel DDR333, if you can get it to 120fsb with the 3:5 divider, it'll be:

120/3*5=200*2=400mhz

Then to figure out bandwidth:

3.2*2=6.4gbps

Let me know when you can get your Epox at 6.4gbps with such a minimal OC. 😉
 
Thanks for the info on the new SiS and the Epox. I'm not sure if I can wait off until that new SiS mobo, or even if I'll actually use that kind of power/can afford it. Since everyone is raving about these Asus boards, and I haven't heard much about the epox, what the differences? I'll definitely wait for Thugsrook's word on the 3:4 of his new P4B533 board till I get one. Thanks yall!

I always like it when people compare stuff that is not available with what you can buy now. Note how I said TODAY in caps. Tell us about it when its out. The 845x boards outperform the SiS boards that are available now. There is always something faster/better/cheaper available tomorrow. Nothing new there.
dvdaction, don't get me wrong. I like ASUS and have probably owned more of them through the years than most people here. The 845 boards they have are limited in several areas compared to others. I came very close to buying the P4B266 for my P4 setup until I really looked at them. The lack of a 3:4 ratio, lower Vcore, and the "turbo" setting compared to a true PCI/AGP lock steered me away from it. I looked around and saw the EPOX 4BDA2+ that had none of those problems. 3:4 ratio and PCI/AGP lock work perfectly. USB ports work when overclocked and there is a higher Vcore available if needed.

It really depends on how you set your system up. If you get a really good CPU and go up past 160 FSB it doesn't really matter as much. Past 150 FSB, you are over DDR400 with a 3:4 ratio which is beyond the limits of available ram. The performance crossover varies depending on the app. Id say a 1.6A @ 2.4 Ghz DDR400 is ~= to a 2.5 - 2.6 GHz with a 1:1 ratio. Using the lower clock speed and higher mem speed means less Vcore, less heat, more stability, no need for a non stock HS/Fan. Different philosophies I guess.

Not really, the P4S533 is the fastest current stock mobo.
You can look on any review site. It OC's well, too. You can take it to over 150fsb with the 4:6 divider, IIRC.
(DDR450)

Which Samsung true DDR333 can handle at 2.7vmem.

Not from what I have seen. The SiS533 is not faster than a 845x at the same clock/mem speed. It slower, and has lower IDE and AGP performance to boot.

Says who? DDR450 is a very tall order. I have that ram. It can not do DDR450. I have not seen anyone do it on any board. There was one guy @ [ H ] OCP that got close. He got DDR448 on a 4BDA2+
 
I'm getting a 2.0a ghz p4, and probably pc2700 samsung ram. In anyones opinions, which should i go for, if people get the P4B533's 3:4 and agp/pci lock and if the usb's work after oc'ing? Epox or Asus?
 
I've yet to see Original Samsung pc2700 hit 450ddr !! Your doing very well to get it stable at 400 , and NO WAY with only 2.7 volts .

If the ASUS has all of that, it should be an excellant board. BTW, the correct EPOX board to compare the P4B533 to would be the EPOX 4BEA, 4BEA+ or 4BEAR which aslo use the 845E chipset with USB 2.0. Flip a coin. BTW, with a P4 2.0A, you may not get to 133 FSB anyway. If so, 3:4 above 132 FSB is a non issue.
 
Thanks oldfart! I realize now that I shouldn't worry about getting a 2.0a ghz over 132 fsb with 3:4. I'm definitely looking into the Epox's now, so thank you! If anyone else has some advice/performance tips with the Epox let me know
 
Actually, if you are not going over 132 FSB, getting the EPOX over a board without 3:4 at 133+ is not as important. At 132 and below, most of the boards including the P4B266 are good choices since they will still have the 3:4 mem speed available. Its when you go over 132 FSB you have to be more careful.

Key words "At the same clock/mem speed."
That's lowering the P4S533's performance by lowering its suggested dividers to the slow speed of the i845 chipsets.

Perhaps that's due to the fact that the majority of the people on this site own P4B266's? :Q

Who would've thought? Checkout www.sharkyforums.com there's people there running their RAM past 400mhz.
 
Well the problem with P4B266, for me, is that it doesn't support usb 2.0, nor will support 533 fsb if I ever want to buy a better chip. I'm really liking what you suggested, the EPoX EP-4BEAR Intel 845E Chipset 400/533MHz FSB ATA133. It's $118 usd from www.ocsystem.com (only 9 bucks more than the P4B266-c from newegg). Anyone buy anything from www.ocsystem.com before? don't know anything about them, as I normally buy stuff from newegg and mwave, and neither of them have a good selection of EPoX mobos. Thanks for all the info so far.
 
dvdaction, I recommend Asus just because I think their boards are among the best in sustaining adequate voltage and temps inherent to overclocking. Asus is very much aware of its competitor's overclocking plans. You will certainly hear about or see other boards overcloking (Abit, Epox, MSI and others) better than Asus but they come short of meeting Asus standard voltage and heat levels in major board components such as psu rail feeds, cpu, ddr, NB/SB, PCI/AGP buses etc.

Apparently, Asus does include overclocking processes while designing their boards like everybody else except they just to trim those features before shipment. If you find an Asus mobo where the lock can be broken such as in the case of the P4B266 with 3:4 RAM ratio above 132 (btw, I highly recommend you check that thread out to get an idea of what I am talking about) then consider that board before anything else.

The above are my own opinions so they have a bias towards Asus and I therefore recommend you check for yourself statistics compiled from other people in this database to determine which vendors lead the pack.

As for DDR450, that is probably the present ceiling for DDR333/PC2700 Samsung chips, just like 180FSB might be for the Intel 1.6a. But, don't let anyone of us stop your sense of adventure cuz DDR450 has been broken into with Samsung PC2700 chips.

Peace.
 
CRAWLINGEYE - THANKS for that link. I will NEVER EVER order from them. Every single msg on that site for OCsystem was slanderous. Looks like I'll play the extra for reliable, on-time shipping for newegg. So it looks like the P4B266-C for me.... I'll forget about usb 2.0 (i don't use any devices that would severly need it), and if I buy another 533 fsb cpu, I'll buy another 533 fsb compatible mobo. Now I have to finalize my case, heatsink, and cpu fan. One last question, I want to buy the ALPHA PAL8942T heat sink, so will the intel fan that comes with my processor work for it or what? Thanks.
 
You can run a 533 Mhz FSB CPU just fine on the P4B266 or other 845D board. I'm running 600 FSB on mine. BTW, if you are still thinking about an EPOX, MWave.com has the 4BDA for $94. They are a very good dealer.
