P4T-533 / 32bit rdram overclocking :

[fkloster]

Considering that Intel decided not to validate the i850E chipset for use with PC1066 memory, we had our doubts about the P4T533?s headroom. Nevertheless, we were able to increment the front side bus until resting at 150MHz as the most stable overclocked setting. Of course this resulted in an equivalent 600MHz system bus and PC1200 memory speeds. Our 2.4GHz Pentium 4 rested comfortably at 2.7GHz, though we suspect the memory modules limited our overclocking attempts, since extra CPU voltage had no effect on system stability above the 150MHz bus setting.

Link here.

Mmmmmm PC-1200 speeds... Mmmmmm....

Overall, we drove our P4T533 Quake III score from 232.6 frames per second up to 255.8 frames per second. That's a nine percent improvement gained by running a 600MHz front side bus and a 2.7GHz processor!

Interesting thing is, the P4T-E with overclocked PC-800 to PC-1066 edges out the rimm4200 rig in some synthetic benches....

The P4T533 is the first motherboard we have seen from ASUS that incorporates the benefits of RDRAM along with features like IDE RAID and NEC's USB 2.0 controller. On top of that, the board delivers performance currently unrivaled by any other platform.

ASUS has stepped out onto a limb as the first to adopt 32-bit RDRAM and we'd like to see the technology succeed, not only because it is blisteringly fast, but also because the ongoing battle between RDRAM and DDR SDRAM results in lower prices and an increasing number of options for the end user, you.

But its the rimm4200's potential to go beyond pc1066 that's so attractive. I've seen two places showing the rimms getting to 158-160fsb @4x speeds.
+ the 1Mhz increments up to 200fsb of the p4t533.

Gotta love Samsung and Asus.

But the RIMM 4200 was also ECC and the PC-800 was not. Having ECC does have about a 5% performance hit on it. So it can only get better!

how about 4037 Sisoft mem at 161 FSB

In the old days it used to be beer that could do that to you.

From the same article - here is what disturbs me:

The most notable omission from the included Award BIOS is the AGP and RAM voltage setting, which often helps coax stubborn hardware into successfully overclocking.

I understand that they were only able to get 150FSB stable. How does this compare to the DDR boards? - especially those that get 160FSB and beyond (DDR "400") for a more attractive price.

This is important to me since I will "only" e getting a P4 1.6A - not a higher clocked chip.

apoppin I thought you left this thread so that we could get back to bashing each other

huh?

I think you are mistaking this thread for another.

Thanks to the "other" thread - and partly your input - I am considering this Asus MB and 512MB hi-perf RDRAM if it is in fact ~$300. Also, my last comment in "that" thread was a comment you evidently approved of ("if Rambus is found guilty of anti-trust violations and manufacturers no longer have to pay them royalties, won't that make RDRAM a more inexpensive and attractive memory solution?")

I think you have been on the defensive for so long that you mistake an honest question for a "bashing".


Now, can you or anyone else answer this question?:

That is probably a limitation of their cpu, although they claim its the ram. I personally think it's their cpu because they were using a 2.4 to get up to 2.7 which is about right for those cpu's and retail cooling.

If you wanted to go beyond 160 you can use the 3x multiplier for the ram. But even with the 1.6 I think you would be better off just taking the higher memory setting of 4x and staying in the 150-160 range.

Thanks.

However, If this board is missing the AGP and some RAM settings, will you still be able to change the RDRAM multiplier?

Also, Tom's Hardware found this same Asus MB lacking performance wise compared to the Gigabyte Board. Of course, Tom also evidently got it worng about the amount of RAM included with the Asus MB.

The clear winner of the test was Gigabyte: rich in features and high on performance, the board takes first place in most of the tests. The manufacturer prices the board at $225 for the complete package, which is not unreasonable when you consider all the features that it offers. By contrast, the Asus board is offered at about the same price, while offering a meager number of features and marginally lower performance.

Don't reply if any of you are offended by my questions. I am considering buying one of these boards and need all the info I can get.

Tom quotes-

In the performance benchmarks, the Gigabyte GA-8IHXP lands ahead of the Asus P4T533-C, and thus takes first place

Notice the -C, this is not the p4t533.
Notice that the p4t533 has the highest memory benches, cpu bench, and multimedia in both sisoft and pcmark?
I wouldn't even consider looking at the fps categories. Most of the boards are within 1/10 second of each other.
And as far as feature rich, I can't see what the Asus p4t533 board doesn't have compared to the others. Tom please explain.

Not to mention he doesn't mention anything about the overclocking potential of the p4t533.
The agp/pci locks, the mhz increments, nothing. You can get more information about these boards from the manufacturers than his write-up.

From what I have read, apparently RDRAM does not take to voltages other than specified, since it utilizes different states of "readiness" that are very voltage sensitive.
I dont think RAM is the holdback, most people that seriously overclock note wildly varying voltages during CPU usage, indicating problems there. Perhaps electronmigration, need for a humongeous PSU (like 650W) or even perhaps we have reached the limit as to what a house line can input reliably. I have seen people who mitigated problems in this regard by utilizing a 1025VA UPS!
I have seen RDRAM posting at 708 (that Macci guy)
Asus has found the ICH4 chip less stable than the ICH2, and the MSI has the 4.

If ASUS does not start selling that board soon, I will explode!

 

[Bozo Galora]

I might also note that ASUS is on their third bios for the P4T533, and i'm pretty sure the reviewers are using the first shipped bios.

Heres screenshot of the PCI/AGP "fixes"

[apoppin]

Thanks for all the info. Uncle Tom was evidently a bit sloppy (again).

Unlike you guys, I don't mind waiting a bit for the Asus MB as I save my pennies. Notice I am again leaving early for work . . . "I owe, I owe . . ."

Peace and aloha,
Mark

Nice review over at tbreak.
p4t533 review

However, our resident overclocking expert Naser managed to leap ahead of me and got the system up and running at 161MHz which is simply amazing. When we reduced the multiplier to 3X, we were able to go as high as 181MHz which we think is the limit for our 1.6GHz Northwood. Pretty impressive.

:Q

I just got goose bumps.

 

[fkloster]

Can anyone say...: "Bang for the Buck" ???

 

[Trashman]

looks nice.....
when can we expect to see these boards w/memory? anyone have an idea.

 

[JackBurton]

Hey fkloster, where did you find that link?

From the "other thread" - in a few weeks.

And yes, if it's ~$300 for 512MB memory and MB, it's excellent bang for the buck (enough to keep a Ferengi like me waiting for a deal and working OT).

So far, I am studying and have bookmarked 4 reviews of this MB. Where is Anand's?

 

[FishTankX]

Hey Fkloster, looks like you got done with your catchup work on RIMM4200. hah..

A quick question. Who'd you mistake me for in the first round of that PM flaming? Zakule?

And, I take all credit for bringing this board to Fkloster's attention. *chuckle*

 

[Trashman]

thanx apoppin, was considering going DDR but, i'm going to hold off a bit longer.

 

[Akaz1976]

So ASUS is gonna be selling this board along with 512 MB of 1066 RIMM for ~300? Thats a pretty good deal when coupled with 1.6 to 2.0A P4s.
