Abit AI7 or Asus P4C800-E Deluxe

[ri3eboi]

If money isn't an issue, what would you get? thanks a lot :D

[All Kill3r]

Hi i have had both of those and like my Ai7 best. If you can solder go for the Asus.

Ai7 gives 3.2vdimm
Asus give 2.8vdimm

Ai7 has stable vcore
Asus does not.

Ai7 has room to remove/install ram without having to take out the AGP. Asus AGP blocks dimm #1 and has to be removed before its accessible.

both of these things need solder mods or smd grabbers so i sold mine for the Ai7 :D

[The Runner]

note: the asus with mods will achieve a higher FSB than the ai7. But the AI7 is a good board also.

[Kanavit]

yea, it looks like AI7 has better ram voltage options. i guess it's good if you want the best performance from ram.

Huh?
I don't have that problem with my P4C800-E.. I can easily remove my memory sticks from the DIMM slots, without having to remove the videocard.

I'd go for the P4C800-E. Once, VDimm and drop modded, it's the best board around.

[ri3eboi]

I don't think I will be doing any hard mods to my motherboard. I never done any hard mod and never worked with soldering iron :(

So without modding, the AI7 will be the way to go?

I got the AI7 from newegg refurb for $55, and I just grabbed a P4C800-E Deluxe for $75. I thought the P4C800-E Deluxe would be a much better board since it retails for $179, while the AI7 only retails for $105.

[All Kill3r]

with a 9800pro and ddr ram i couldnt use dimm #1 unless i removed agp to intsall/uninstall on the Asus board....

n3eboi, Ai7 >P4C800 unmodded.

[SPQQKY]

Well, I didn't have a P4C800, but I did have a P4P800 and I gotta say with the vdimm mod on the P4P800 is was an excellent board. I just like my AI7 better due to the adjustments for voltages being right there in BIOS, no opening the case or leaving it open to adjust pots. I like my system in a case where it belongs. Plus the AI7 OCed better and more stable for me.

[eva2000]

AI7 unmodded with the right ram (BH-5/6, CH-5/6 or OCZ EB) is better than P4C800-E check out what's rank'd #5 at BE Memstat contest http://www.bleedinedge.com/forum/memleaderboard.php beating alot of P4C800-E and IC7 series boards!

[ri3eboi]

Thanks for the info guys, since I am not gonna mod my motherboard, I will go with the AI7 :D.

Damn it I guess I am stuck with Abit :(. All of my performance motherboards are from Abit except one Soltek :(. I have never had an Asus board :(

[a5h]

why not get the Asus then ...for extreme FSB, its wayy better.

whats the highest FSB these AI7's can go? on average.

[ri3eboi]

I have no idea lol.

Actually I am not really planning on overclocking my P4 3.2, at least not for now... I do not think its very overclockable anyways hehe.

What speed do you guys think I can reach if I am to overclock my system?

I am getting a Thermalright 948U Heatsink (Will this have any problem fitting on either motherboards?) with Panaflo or Tornado 92mm fans, and Antec True550W PSU.

Btw is the mod hard to do on the Asus?? Man I am again feeling the urge to overclock ;) Can someone link me to a guide to the aforementioned modding to the Asus board? Thanks a lot

[All Kill3r]

slk-947 fits my ai7 fine, dont know about asus as i used a diff heatsink on it.

Asus mods - http://www.xtremesystems.org/forums/showthread.php?s=&threadid=13402

[SPQQKY]

SLK947U works fine on both boards. The vdimm mod on the Asus is almost too easy. I used grabbers for the pin and just attached an old fan header to the other end of the wire and plugged it into the mobo for ground.
AI7 reaches some phenominal fsb's. The chip is the key, though, a poor OCing P4 will hold you back.

[Karnivore]

Never saw any indications of the AI7 being FSB limited, have had almost every 865/875 board there is, AI7 is a great board, and compares well with any of the others. Here is a shot of the AI7 under a halfway decent processor..

[ri3eboi]

dang 4500... crazy! What kind of cooling you have? And is 4500 stable for everyday operation?

[SPQQKY]

LOL...halfway decent???????? I would say all the way decent! I mean 4.5GHz is about as much as you could ever hope for.

Unmodded Mach I cooling, and yes it is stable.

[Slickthellama]

AI7 has problems over 250FSB. If you plan on going higher get the P4C800 but below that get AI7.

Slick, My AI7 has no such problems, not board specific anyway, It does however suffer from the same problems as most other 865/875 boards (RAM related) however the same problems exist on the Asus boards. If you have specific incidents in mind I would love to see links.

As you can see from my screenshot, 302 fsb wasn't to much of an issue, far as i know 302 is a bit more then 250:confused:

[Tedinde]

I had my AI7 to 290fsb before my CPU crapped out. Mosfets are smaller on the board and run cooler. The mem scores arent near my original IS7-e. "Pat" is not there I dont care what anyone says.

I used to be able to his 6.6-6.7k over a year ago with my IS7 and i have screenies. Best i could get with the AI7 was 6.2-6.3.

But right out the box i've been using the AI7's for customers rigs. Stable as can be.

And the AI7 has no problems above 250fsb. If you search the forums Me and EVA2000 had the first 2. These forums and overclockers. Both of us were way above 250 fsb with the first releases of the boards.

I will not buy another ASUS after getting burned w times on their crappy Rdram boards years ago. After they sweared they were "overclocking boards". With no PCI lock.And paying way over $200+ for them, only to swtich back to my TH7II. But that's another story.

[SPQQKY]

I have absolutely no problem hitting 275 fsb on my AI7 w/ a 2.8C.

[eva2000]

yup no probs with my recent 2x 2.8C SL6Z5 MOs both reach 280-281fsb on AI7 and P4C800-E (at a higher vcore than on AI7) both boards unmodded

in Aus AI7 is $157-190 still, wish it was as cheap as US$99 ~AUD$130

I think AI7 would make a very decent budget board sub US$99 hehe

[ri3eboi]

awesome! I can't wait til all the parts come in so I can slap this AI7 in and play with it.

[computerpro3]

go p4c800-e deluxe and get hellfire to mod it for free. Much better board. This is on AIR with my 2.4C. mwhahahahah

I've also got 4ghz with water on it. AS well as 534mhz 2-2-2-5 memory.

[Karnivore]

Yep and its also almost twice the price...

With Abit AI7:

[computerpro3]

not on air though, is it? If I tried that chip with water while I still had it or prommie or whatever cooling you have on that one, I'd blow right by you. Besides...

[Mace]

No, it's water cooled and this one also:

http://sivut.koti.soon.fi/macce/pics/pifast33P4.png

Mem 1:1 2-5-2-2

[computerpro3]

Are you serious, 4300mhz watercooled.....thats got to be the highest overclock on straight water I've EVER seen. Even 3.4ghz EE only do around 4ghz-4.1 on water.

Anyway, looks like the boards are pretty much equal up to a point in terms of OC ability (I say up to a point because we aren't in the realm of 4.8ghz dual cascade yet) but I guess 4ghz/267mhz 2-2-2-5 + is good enough for most people.

What about performance wise? What do you get in SANDRA unbuffered?

The Ai7 certainly seems a great board for the price...

Yes, I'm serious cooled by water...mean cold water ;)

Sandra unbufferd: ~3750/both when FSB is 250MHz.

[computerpro3]

LOL I thought it was straight. My bad. Performance wise, with my 3.0C at 260mhz 2-2-2-5 I got 3900 unbuffered on the dot. Thats with turbo and performance mode off though. my system is outta comission right now as I am awaiting the new 2-2-2-5 corsair memory to hit the market; i sold my bh-5.

What temp is your water at?

It's straight. As you probably know we had cold spring on Finland in this year ;)
Water temp ~+-0ºC

[computerpro3]

by straight I meant normal, room temp water.:)

nice temps. I'm hoping to get a waterchiller started myself...will be aiming for -20C water temps. Then I will add a TEC to my gpu and cpu. I'm hoping for 4300mhz at least. I can't wait :D .

Good luck :toast:

[a5h]

Do these AI7's handle a prescott well?

i heard they can't handle them well, or is this wrong?

[Mace]

As far as I know AI7 is socket 478 mobos one and only that can handle Prescotts w/o trouble. Correct if I'm wrong.

my IC7 handles my 3.0E ES no problems at all. though i am interested in buying this AI7 for the higher voltages for the memory. just one question does the AI7 have the PAT? ive heard mixed results on this. some say it doesnt and some say it does?

peace perc,

[eva2000]

AI7 full PAT enabled when

1. NB Strap 667fsb 1:1 or 5:4 is set with GAT minimum A-A-A-D-D
2. NB Strap 800fsb 1:1 or 5:4 what GAT minimum F1-A-A-D-D is set

when this occurs cpuz cpu/ram ratio is buggy and reports wrong ratio but it works so 250mhz 1:1 with FULL PAT cpuz reports 200mhz 5:4 although the system is 250mhz 1:1 which shows in benchies

this is 2x 512MB OCZ PC3500 Plat LE BH-5 @ 250mhz 2-2-2-7 at 3.18v vdimm on AI7 with 667fsb strap and GAT = A-A-A-D-D with FULL PAT enabled

unbuffered = 3828/3801 !

[CrashOv3r1De]

I would go for the AI7 unless your going to be using a Prommy or a Vapo on the board because you will have to do a mod. The socket is angled 45deg

Id trade my 3400+ and k8npro for a AI7 with 3.4E anyday :) Intel ownz meh
