<< One thing people forget is with that the Asus P4B266 offers some of the best memory bandwith out of all the i845d chipsets. With good memory and its 3:4 function you can hit very high memory speeds. Right now with crucial DDR im running the memory at 160FSB which according to sandra 2002 is equal to PC800 RDRAM speed. Most overclocked i845d boards will have memory benchmarks from the 2000/2000- 2200/2200(high overclock) range. I'm at 2500/2500 in sandra right now and the P4 really loves that extra bandwith. >>
You are correct. But, I think that because 845 Ultra ARU hits the same fsb with all DIMM's populated as P4B266, and because he wants ATA/133 (which P4B266-E which is the only P4B266 that has ATA/133) that 845 Ultra ARU is a better value, expect for.....
<< you are wrong on a couple counts
the Gigabyte can run with 2 doublesided memory modules at over 133fsb
(the 845d chipset only supports 2 rows of doublesided memory)
the only other issue the 8IRXP has is once you manual set the voltage the system wont restart or boot once shutdown, (you have to unplug the power for 5 sec)
but then it runs strong and hard
and is the only board that allows you to run @ 1.85 volts without any modifacations
contact visionary over at vr-zone.com and he'll tell you the same >>
I stand corrected on my complaints about 8IRXP.🙂 But, IgoByte, don't weigh too much on the voltage up to 1.85 because if you run a Northwood at that high of a volatge, you will significantly reduce the life of the CPU. The "safe" voltage AFAIK is around 1.65v at the max.
<< THe MSI is the worst board you could get, >>
Strawberrymom, I too am curious as to why the 845 Ultra ARU is the worst IgoByte could get. In Anand's 845-D roundup, it was only beaten out by 8IRXP.
<< Which ASUS board is the best and why? >>
Ok. What about P4S333? Well, the real issue with it (and really every other SiS 645 board except for one, EPoX's but it doesn't have all the features as the 845-D boards here) is that they don't oc any where near the levels of 845-D and 850. Now about Asus' 845 board's. Here's they are:
P4B: Bare, no SDRAM slots. Avoid IT!!!
P4B266-C: Bare. Great ocing, no sound, ATA/133 or USB 2.0. Most common
P4B266: USB2, and Audio. In plenty of stores, but not at Newegg
P4B266-E: USB2, Audio, and ATA/133. Yet to be seen.
So, I do not know the price of P4B266-E but considering that the P4B266 is at this point more expensive than MSi 845 Ultra ARU which has all P4B266 has and is cheaper so it stands to reason that P4B266-E will be even higher compared to 845 Ultra ARU. So, to sum up here's my take for your situation (I am going to omit P4B266-C because you want ATA/133 and USB2 and I'm gonna omit P4B266-E because it's nowhere to be seen):
P4B266:
Pros:
Solid board
Prolly the best oc'er of all these by a hair over MSi 845 Ultra ARU
Cons:
Lacks ATA/133 you want
Expensive compared to some of these boards ($142 cheapest price, and not at Newegg.com)
MSi 845 Ultra ARU:
Pros:
Great Price ($136 at Newegg)
Has ATA/133, USB2 and Audio
Ocing comparable to P4B266
Cons:
None that I can see unless unless there is some serious problem with it (waits for Strawberry to respond)
Gigabyte 8IRXP:
Pros:
Same features as 845 ultra ARU plus LAN
Good ocing
Cons:
Expensive, compared to the other boards.
It's up to you. I think that from a stability standpoint all are equal, but in terms of overclocking, I really, hestate on 8IRXP (maybe Strawberrymom can tell use where did he max out on fsb when using only 2 DIMM's) because it hasn't been tested with 2 DIMM's for it's ocing. So, personally, I still stand that I feel 845 Ultra ARU is the best value for you. If you want Dual BIOS, and Audio but are willing to sacrifice a tad in ocing, and willing to pay a bit more, then go for 8IRXP but otherwise take 845 Ultra ARU, and at this time, P4B266 shouldn't even be considered when the 845 Ultra ARU has better features, similar ocing, for less money. Any Questions?🙂
