Asus P4T533-C & 1066 rdram

[Den]

I am having exactly this problem. When trying to post I get one long beep repeated over and over. When I took it back to the place I bought it they tried it with PC800 (since they did not have PC1066) and since that worked, they concluded the memory was bad. So, I RMA'ed the memory with Kingston, but if you are correct, it will be just as bad with the new ram. If so, I guess I have to try and get them to swap the MB.

Bummer.

Everyone also may have heard of people who have been having POST problems with the Asus P4T533-C, PC1066 RDRAM, and the P4B processors. Right now, no one knows really what causes the problem, but I am relieved to report that I have experienced nothing abnormal from my system. As far as we can tell, the problem is not caused by the manufacturer of the RAM (both Kingston and Samsung have been in culprit systems), and it is not limited to any specific processor frequency (2.26, 2.4, and 2.53 are all affected alike). The only thing that we can conclude is that the problem most likely lies in the motherboard.

Actually Den, it looks as if my original assessment of the motherboard being at fault may be incorrect. A few people have now tried their system with PC800 RDRAM, and it has worked, so it appears as if the PC1066 speeds of the RAM are causing problems. My guess is that the new RAM (PC800) will work in your system. Why don't you try lowering your RDRAM multiplier to 3x (using your current PC1066 modules) in the BIOS, and then booting up. If my new assumption is correct, it should work just fine. My new train of thought is that the problem is with the PC1066 speeds, but then again, no one really knows at all.

MY PC1066 is currently being RMA'ed (its in the mail). I am currently using the machine with PC800 and it works fine. It will be interesting to see if it works with the new memory (new sticks of PC1066) or not. If it does not then I have to wonder who can't handle PC1066, the MB or the RAM.

 

[jbond04]

Well, Den, it's impossible for your processor to not be able to "handle" the RAM, since the processor has nothing to do with the RAM at all. It could care less what speed or type of RAM it runs on (of course, performance will vary), as long as it runs at its intended frequency. If I remember correctly, you are getting to hand-picked PC1066 modules, correct? If those don't work at PC1066 speeds, then it is obviously the fault of the motherboard.

And for the rest of you still reading this thread, here are some benchmarks for my overclocked 2.7GHz P4:

SiSoft SANDRA:

2.53-4919 MIPS, 3120 MFlops
2.7 -5236 MIPS, 3297MFlops

2.53-10083 it/s ALU, 12053 it/s FPU
2.7 -10723 it/s ALU, 13072 it/s FPU

PC1136 RDRAM-3578 MB/s ALU, 3573 MB/s FPU :Q

3DMark 2001:

2.53-8120 3DMarks
2.7 -8395 3DMarks

Temperatures:
49C full load
35C idle

It really baffles me why my processor won't overclock to 2.85GHz. My RAM should be able to hit PC1066 speeds, and since I'm hitting 2.7GHz at default voltage, I should easily hit 2.85 with a little bump. My processor temps don't look abnormal, and I only have one hard drive and a videocard in my system, so I don't think the PCI or AGP buses being out of spec are causing the instability. When I get home from work tonight I will push it further, and test the limit.

I'll update then (I promise )

try setting your HDD's to PIO mode 4 in bios, dma disabled
take out any nic card

 

[Scipionix]

Doesn't crippling your hard drive kinda defeat the point of clocking higher? Oh right, it's about the benchmarks

 

[Den]

Obviously it is not a processor problem, I have never mentioned that I thought it was. I am not getting hand picked PC1066, I just called up my vendor who had me call the RMA number at Kingston. They said they will send out the same parts I sent in. You are confusing me with someone else. I sure hope it is not the MB cause I know my vendor will just say, "it works with PC800 it is fine".

I went to Kingston this morning and they worked on my PC for about 2 hours, I did not have the long beep problem untill I cleared cmos, after clearing it the PC could not see the ram. My 1066 Kingston ram was fine. In bios you need to set X4 and not auto but the problem is it keeps defaulting back to Auto. If you have the P4T533-C and 1066 ram of any type DO NOT CLEAR CMOS because it will not boot again unless you have PC800-40NS ram sitting around to use to boot it back up. This is how Kingston rebooted my PC.
Kingston is talking with Asus about the fix. It is the board and its a factory setting that needs to be fixed with new bios.

 

[Bozo Galora]

Thank you, excellent info, and nice job at taking it right to the source.

Of course, that begs the question - DONT THEY EVEN TEST THESE THINGS BEFORE THEY PUSH THEM OFF ON THE PUBLIC???
ASUS used to be top notch, now they just rush everything out like everyone else, and hope for the best.

Sorry about the confusion. There are about three threads that I am trying to follow at once all on this exact topic.

Yes, it does. I don't plan on compromising any other part of my system for a few more megahertz. *cough* DDR Users... *cough* j/k

And sppsr, GOOD WORK! Thank you for helping to solve this problem for everyone who is affected! It's good to know what causes the problem, and I'm sure Asus will come up with a BIOS update for it (they're usually pretty good about fixing problems). Great job!

Hi bozo
I would agree it was a rush to be first on shelf, and they ended up shooting their self in the foot and making a lot of people mad.

I was going to ignore you again, because you seem to want an argument all the time, but since jbond picked up on something you actually addressed to me:

I DIDN'T RECOMMEND JBOND RUN HIS MACHINE IN PIO MODE 4 FOR THE REST OF HIS LIFE - JUST TO TRY IT, SINCE IN BOOTING PROBLEMS THIS SOMETIMES HELPS TO GET INTO WINDOWS!!!!!!!

Is that O.K. with you?
The fact you thought I meant otherwise says a lot about your knowledge about this stuff.

Edit: If you want arguments - go beat up your kid sister.

sppsr:

yes, thats my take. you are to be commended for taking your box to "the peeps" themselves and saying "you figure it out".

the very reason for the ASUS board IS TO RUN ON PC1066!!!!

 

[ManojM]

I have the Asus P4T533-C and I must say that it is the best motherboard for the Northwood in the market now.

It is 100% stable. I have my Northwood 2.2Ghz (ES) clocked at 3Ghz (20 * 150mhz fsb) with no problems. My Kingston PC 1066 rams are running at PC-1200 speeds without a problem.

I can also run my system at 152mhz fsb at 4x bus mode but 3DMark 2001 SE is not 100% stable. It gets me back to the desktop near the end of the benchmark.

However, I am glad that at least 150mhz fsb at 4x bus mode is 100% stable.

Now I am planning on using the Turbo PLL on this motherboard and setting higher FSB settings for more fun at 3x bus mode.

This motherboard just rocks!!!!!

 

[jbond04]

It's so unfair when people get engineering samples. :|

 

[Bozo Galora]

Damn, I would kill for an ES.
Uh, where'd you get yours?
What month is it?

Since I'm waiting for the P4T533, I'm at a disadvantage here - what are we talking about here on PLL Turbo?
This????????

I would be REAL interested in your results!!!!
First post since Feb registration? - c'mon in, the waters fine.


Edit: Also: Does everyone here have the 1004c - 7 bios for trial?
here

 

[ManojM]

The Asus P4T533 supports 32bit Rambus and I am not sure about the overclocking potential of the motherboard. Asus P4T533-C only supports up to 150mhz fsb in the bios but 152, 154 and 156mhz by dipswitch.

With the Turbo PLL modified to the motherboard, I can set higher FSB setting with nice PCI and AGP dividers. It will be like running the Abit TH7II with the new DRCG.

I also don't want to get the 32bit Rambus since they will cost more than the current 16bit modules and also not many motherboards will support the 32bit modules and soon DDRII will release.

I bought 2 sticks of 256megs Kingston PC 1066 for only $105 each.

OOps, you posted while I was typing

The latest info on DDR-II I've seen is LATE 2003 (but who knows)
by then we'll have RDRIMM 9600

Looks like SIS 658 chip (RDRAM) might keep Rambus "alive" after Intel drops it. (Man, I never thot I'd be pimping RDRAM)

 

[Bozo Galora]

I personally think that while kingston uses Samsung chips, I'd rather have "FULL" Samsung - PCB and everything - they are really making the best ram today (IMHO)
Also noticed Corsair PC1066 rated at 30ns - have to call them about this.

Keep posting man, locked AGP/PCI really would make this the perfect board. I could actually be happy for a few months.

Actually I think it says more about your sense of humor. If you think for some reason that I like to start arguments with you in particular, there's not much I can do for you. If you would like to continue this in private, go ahead.

 

[Bozo Galora]

O.K. If you were trying to be humorous, I missed it. Maybe I'm just dense.

Sorry then

 

[Bozo Galora]

And BTW:

Doesn't anybody on this forum ever sleep???

 

[Scipionix]

I'm always trying to be humorous. Except when I want to beat jbond's benchmarks, whicih I think I'll do right now.

 

[ManojM]

Intels' offcial motherboard with true DDR300 or DDR400 will release in August.

 

[Scipionix]

Manoj, do you have the switch settings for fSB settings over 150 MHz? They're not in the manual.
