Very good news!
I'll be using one with my 2.66 to see if the Canterwood architecture will help me hit 3.9+. 845PE has me up to 3.8+
With Prommie...maybe 4gHz...

[Chong345]

Hehe. Good luck. I hope you get there. There might be limited quantities of the ABIT board though at first. I would rush to get one if you find one.

I just know I'm going to be the last guy here to get the IC7-G .. Damn canada sucks for getting the NEWEST I still can't get a 9800 pro until the 25th...Oh well, sit and wait I shall...

[calantak]

somebody care to answer my question
can we async 133 mhz cpu's on the canterwood boards,
because running a 3.06 @ 166 fsb would happily need a divider to get some bandwhith...

[Chong345]

I have no idea what the BIOS options are like for this board. From what I have heard there are divider options like the ones you are describing. As for which board, the person I was talking to said he could not comment on that.

I read the reviews and such but it's too much cabbage for me atm to go with canterwood


I'll probably wait for Springdale

[Xenogias]

I'm almost sure that there are dividers. I looked at screenshot of Abit's Bios on Geil's website and they showed an option to set dividers, just not which dividers. I would imagine that you would get async dividers from the Taiwanese chip makers to run rma faster than FSB. Surely, they have dividers to run it slower! Even intels board will have that.

As for Springdale: Isnt that geared less at the performance/enthusiast market and more for the mainstream and small business?

[Zroc]

There are dividers to run the memory less than 1:1 (such as 5:4), but not to run more than 1:1 (like 4:5 or 3:4), as there really is no need to give the P4 more bandwidth than it can use (at 1:1, the memory and FSB bandwidth are equal).

[calantak]

a p4 can use more bandwhith at quad pumped 133 mhz then 133 mhz on the ram...

[Zroc]

Single-channel, sure (FSB 133x4x8 is 4.2GB/s bandwidth, DDR single-channel 133x2x8 is 2.1GB/s). But dual-channel DDR at 1:1 matches the P4's FSB bandwidth exactly (FSB 133x4x8 is 4.2GB/s bandwidth, DDR dual-channel 133x2x8, x2, is 4.2GB/s). For the new parts, it's FSB 200x4x8 for 6.4GB/sec of bandwidth, tied together with dual-DDR 200x2x8, x2, 6.4GB/sec.

This is why you see Sandra typically use in the high-90%'s with single-channel DDR, because the memory is not providing the FSB with enough bandwidth (even at 4:5 or 3:4 single DDR ratios). Many people refer to this as 'efficient', when in fact, it is really showing that the memory bandwidth is quite insufficient to allow the FSB any breathing room. With dual-channel 1:1 (or RDRAM 4x), the mem bandwidth is more than sufficient, and you'll see the FSB only using in the 70%'s of the available bandwidth (the FSB can't use 100% of the bandwidth because of overhead from other operations).

Adding even more bandwidth at that point would do next to nothing (less than 1% difference, if not in fact SLOWER due to asycronous operation, as you see in nforce2's).

So all u guys are saying Abit IC7-G, Hoo-Ra, Abit IC7-G, Hoo- Ra, but what if the gigabyte or Asus Canters outperforms Abit are u still goin to remain Loyal to Abit IC7-G.

[calantak]

hehehe

well, we'll see, the asus looks extremely performant and hi-fsb minded

[Raptor]

i'm just looking for my Epox!

uhhmmmm

no ?

the bus will always be multiplied by your multiplier, no way around that.

[Raptor]

it seems Epox 4PCA3+ will be released to stores worldwide next thurday!

I can hardly wait!

[taco]

any idea how much the 4PCA3 will cost? im guessing this is the one without raid and some other goodies.

[Jupiler]

Around 199€
The cheaper version would be about 30€ less.

You got my point

I have an asus right here next to me, I'll try it out and see what I can do with it

Same here!

Thanks for the update Raptor, best news I've heard all day.

I like this one because I plan on running RAID5 with four drives. If I go the Asus or Abit route, I'll be into it almost double the price.
True the EPoX HPT374 PATA RAID5 is software controlled, but with a fast processor, the overall system performance should really rock.

You did notice that they added the P4 power connector back that they did without on the 4T4A. The Techs said it wasn't necessary, but popular demand proved otherwise.

I'd laugh if it takes the OC lead over Asus and Abit--not holding my breath, but it would be funny.

[ScissorClaw]

Okay, where on Gods green earth can we actually GET one of these chips? I got the money, just can't find the chip!!!!

Dog, you actually won't want to do that...you'll get better performance from two SATA drives and ICH5R than you would with a PCI card.
Refer to my earlier post...

Wow! Thanks Zroc. I had my mind made up and would have wasted some bucks--had no idea that the PCI bus posed that much restriction on throughput. That certainly explains why most 4 channel RAID cards use either 64-bit or the run at 66MHz.

So do you suppose the EPoX solution for 4 channel onboard PATA RAID is DOA?

[Zroc]

Purty much...it has to use the PCI bus, as ICH5R is only two-channel.
It would still be useful for RAID 0+1 or RAID 5, if it's capable. But if you're like me, I'd rather use the three drives in a RAID 0 + one drive for Ghost/imaging backups scenario. Then you have the speed AND the backup.

[Dog_One]

Not sure what they were thinking with the design of this board. One site indicates GbE via the MCH (which should be CSA) only the board has a Broadcom GbE controller. The other site makes no mention of CSA or MCH Ethernet. Hmmm...

I was kind of hoping that the EPoX engineers found a way to connect the Highpoint controller to the CSA bus and then had to use the PCI GbE solution. Now I'm not sure what to think.

Maybe it will be a great overclocker. It seems to be the last one out of the shoot, it better have something going for it that the others don't.
