CPU Frequency Problems - P4 2.53 533 bus and Asus P4T533-C

[ProfessorFate]

My buddy had this same problem and fixed it by switching positions of the Crimms and Ram.
He is running the P4T533-C, 2X256 Kingston, 2.4 Intel chip. Since the switch his sys has been rock solid.

 

[Shagga]

I have the ASUS P4T533-C and a P4 2.4(B)GHz CPU along with 2 x 256MB of Kingston RDRAM (PC800). I have not experienced any instability problems whatsoever. However, it may be because you are running PC1066 different to the Spec recommended in the Manual (SAMSUNG).

Have you tried updating the BIOS. My mobo came with Version 1003. I flashed the BIOS to 1004 Beta 7 the other day and have experience a much faster boot time. Perhaps this may solve some of your problems you are experiencing. The EZ-FLASH works a charm by the way.

Same problem - I cannot get my new rig to run correctly. Posts and runs good at 1.7GHz, but will freeze during post when i try to get it to run at 2.26GHz!!!

I have heard about this problem elsewhere - let's solve this because ASUS support has no idea!!! Your help and expertise are GREATLY APPRECIATED!!!

Hmmm, i got the same setup ordered, a P4-2.26 + Asus P4T533-C motherboard, i will probably get it by the end of the week, hopefully. I wonder if there are problems with this Motherboard, i plan to run this on Win98SE since although i might want to switch to XP if it is unstable.

 

[sao123]

Does anyone have WinME running stable on the Asus P4T533-C board?

Here is my configuration... I need help. System Bluescreens randomly when I use DirectX Game or Application.

P4 2.4B 2405Mhz
Asus P4T533-C 533 FSB (33/133)
1024MB of PC1066RDRAM running at 1066 (x4)
Visiontek Xtacy G4 TI4600
SB Audigy Gamer
Dxr3 DVD Decoder Card
US Robotics Performance Pro 56k Modem
Maxtor ATA 133 IDE Card w/ 3 Maxtor 80GB ATA133 drives each cooled by 2xHDD plate Fan.
ATAPI Zip 250
Plextor 40x/40x/12x CDRW
Creative 12x DVD
400w Power supply
6 Case fans.
No overclocking, use of all manufacturer driver (CD's included)

Any Ideas

Just curious but where are you finding the 1004 beta BIOS? I can only see a 1003 beta 002 on ASUS's FTP. I'd like to see if the newer BIOS solves my problems (looong POST time when Kingston 32ns RAM set to 4x and inability to disable serial/paralell ports without WinXP refusing to boot).

Thanks in advance,

 

[Zarach]

Thanks all for the advice. I have looked into BIOS flashes and have been a bit apprehensive about flashing to a beta BIOS version.

I have been on the phone with ASUS AND KINGSTON tech support and what a farce that is. ASUS technicians haven't even dealt with this motherboard nor were they even aware 1066 RIMM's were even on the market.

The guy at Kingston seems to think it's a memory issue so he has apparently hand picked me two RIMM's that he tested with this particular motherboard. I should receive these tomorrow.

ASUS upon return call thinks it may be a power supply issue, however I highly doubt that since I am running a 350W supply and have previously had 300W with the same peripherals installed.

I will post more tomorrow when I get my final verdict with the new RIMM's.

That's a lot of stuff. Did you try booting with all the PCI cards and IDE/ATAPI drives disconnected? See if you can get to the part where it tells you it can't find an OS. If it does, I'd suggest adding the SCSI card and one hard drive and seeing if that works. Then add the rest of your peripherals one at a time. Of course if it doesn;t work with just the MB/CPU/RAM and a video card, I'm stumped. Also, is your power supply sufficient for all that hardware?

Maybe try it with two memory modules instead of four?

 

[Dru858]

- BIOS freezes during post (and IntelliMouse Explorer blinks rapidly)

Does the BIOS freeze or does it jsut take a long, long time to POST? Because mine appears to freeze but if I wait a good 1-5 minutes it will boot from the OS. Maybe go grab something to eat then come back and it will be booting.

 

[jbond04]

This blows my mind...

I guess I am among the lucky who have experienced nothing but speed and stability, since there seem to be so many people who are having a problem. The only thing I can think of is this: what is the voltage to your processor? My 2.53GHz P4 (which is supposed to run at a default voltage of 1.5v, I believe) is actually running at 1.6v VCore! I don't know why it would be doing this, since I have the VCore setting in the BIOS set to "Auto", and have even tried to decrease the VCore to 1.4, but my only conclusion is that my mobo is over-volting my processor. Now, this may not even make any sense, and is a huge shot in the dark, but what if the problems that everyone is experiencing at higher clock speeds are caused by the processor not getting enough voltage?

I don't think that this is a RAM issue, otherwise, you could set your processor to run at full speed, then decrease the RDRAM multiplier to 3x to get the system to work (of course, that isn't necessarily a solution). And I highly doubt that this is a power supply issue, since it seems that so many people (who probably all are using different power supplies) are experiencing this problem.

Here is some more information about my RAM/Processor:

RAM Model Number: Kingston 32ns PC1066 RDRAM (KVR1066X16-8/256)
Processor SL Code: SL682 MALAY

Good Luck!

 

[Dru858]

Antec PLUS880 Case w/ True430 power supply (Mikhailtech recently did a review of the 330W version, and it got good ratings)
P4T533-C BIOS Revision 1003 Beta 002
Pentium 4 2.53 GHz SL682 MALAY
Kingston KVR1066X16-8/256 (2x of course, in RIMMA1 and RIMMB1, C-RIMMs are in RIMMA2 and RIMMB2, I've tried reversing the config and rearranging modules and no improvement)

BIOS Settings are all setup default except:
Floppy=None
CPU=Manual
FSB/PIC=133/33
RDRAM=4x
Boot off floppy=Disabled

ASUS Probe reports my Vcore as being consistenly 1.536, and I have the BIOS set to Auto and it indicated 1.50 as being the default. I have absolutely zero stability problems within Windows XP. The things runs so rock solid you wouldn't even begin to think for a second that it gives me problems when it POSTs. For instance I rebooted tonight and it took 1-2 minutes to POST instead of the traditional 15-30 seconds that I was used to on my old CUSL2 + PIII 733 computer. Also when I disable the onboard serial and parallel ports Windows XP and the Windows XP boot CD will not load it just sits there at a black screen.

The only thing I can think of is a BIOS issue. Everything runs so stable once the system POSTs it's rediculous to think that it'd be a CPU, memory or power supply problem in my opinion.

 

[Scipionix]

jbond and dru, you both have the same memory modules I do and after five days I still don't know why your systems aren't working right. All I can figure is that there might be some compatibility problems between your Northwood B processors and the board. The four of you who are having serious problems are running 3 2.53s and a 2.4B between you. I don't know if anyone besides me has tried this board with an "A" processor, but that is the only difference I can see between me and the people with all the problems. I did notice that the SL682 processor is sold in both the OEM and boxed versions while the SL685 is only sold in the retail box. As for what to do about it, I don't know, but I have a growing suspicion that there must be some reason why the 2.53Bs in particular are having the most trouble that doesn't have anything to do with the CPU or FSB frequency. I'm disappointed that this many people are having trouble with an ASUS product since until now I believed that ASUS boards were by far the highest quality boards around.

 

[Scipionix]

Have you folks tried UNDERCLOCKING to the 120/30 setting in BIOS? That would be 2160 for the 2.4B and 2280 for the 2.53. Leave the RDRAM multiplier at 4x. I suspect it will work.

 

[jbond04]

Scipionix, I don't have any problems with my setup. I'm just here to try to diagnose the others...

And Dru, the BIOS detects my VCore as 1.5v also, but the Probe is reporting it at a little under 1.6v. Weird. Oh well, no POST or stability issues here at all.

 

[bmd]

I've had my P4T-533C system up for about a day now and I've had no problems whatsoever. Processor is a P4 1.8A and it's running rock solid @ 2405Mhz with the retail HS/F (I did bump the voltage up a bit though). My RAM is Kingston PC800 but it's running fine @ PC1072 speeds. Sorry to hear you guys are having trouble... anyone try upping the voltage on their processors and seeing if that works yet?

 

[Den]

I am having the same problem you guys had. I bought Kingston PC1066 (2 of em), the ASUS P4t533-C and a retail P4 2.53. Whenever I tried to POST I would get the one long beep (repeating) indicating memory failure. I tried it with Kingson PC800 and it worked fine, so I have RMA'ed the memory. We will see later this week if it was the RDRAM or if my particular MB will just not do PC1066. If it does not work, maybe I will send JBOND my RIMM's and see if they work for him

Dan.

 

[jbond04]

Den, have you tried setting your RDRAM multiplier to 3x in the BIOS? This should see if your RAM is defective or just can't run at PC1066 speeds. In this case, it sounds like this isn't the motherboard's fault, so I would try to see if you can just decrease the speed of the RAM (this isn't a solution, just a troubleshooting measure) to see if that helps any.

 

[Den]

I will test the PC1066 at both x3 and x4 when i get it back. Does your PC1066 work at PC800? If you set it to x3 does it boot and work just fine? If so, you are right this will be a good test, since I know my MB works fine with PC800, it PC1066 is supposed to work at 800mhz speed as well, then I can know pretty well for sure if the ram is good or not.

Thanks,
Dan

 

[jbond04]

Den, my board works fine at PC1066 speeds, with my 2.53GHz P4 and my Asus P4T533-C. I haven't been experiencing any problems with it whatsoever, so I am just trying to throw out some suggestions. Therefore, my board will work absolutely fine no matter what my RDRAM is set to (3x, 4x, or Auto). You, on the other hand, are having boot up problems with your setup at PC1066 speeds, which is why I am suggesting that you lower the RDRAM speed, that way we can figure out if the entire module is defective, or if it is having trouble hitting its rated speed.

 

[Den]

Like I said before, I RMA'ed the RAM so hopefully when I get it back all will be well. I just wanted to confirm that you have sucesfully run the PC1066 at PC800 speed, I knew it worked at PC1066 I am currently using it with PC800 and it works fine, so with any luck when I get the new PC1066 back it will work at 1066. So you just ran it at PC800 speed for fun? Guess it would have been cool to see the difference in benchmarks...

Thanks For the help,
Dan

[Den]

Ohh, just realized my last post was not clear. I have some other memory, which also happend to be Kingston. It is normal PC800 sdram, when I run the board with that memory, it runs good and stable at 3x or Auto (PC800). I never did try the PC1066 at x3 becuse I could never get to the bios to set it, and I do not know how to change that with jumpers. Now that I have the PC800 ram, I can of course use that to set the bios if I need to try the new ram at both speeds.

Thanks,
Dan

 

[Bozo Galora]

the other PC1066 thread here has found the problem - its not the RAM
its the bios resetting to auto each time

 

[jbond04]

Just to elaborate a little bit more on what Bozo Galora said about the source of the problem:

It's the motherboard's fault. Apparently, it will not boot in some cases unless 40ns PC800 RDRAM is inserted. Kingston is said to be working it out with Asus right now.

 

[t0pher]

UPDATE!!!

BIOS 1004.007 fixed my problem. I'm guessing it's either the combo of 40ns PC800 RDRAM st 533 or a USB 2.0 problem. Either way, it boots fine at Auto or 3x memory, but i get s STOP blue screen when set to 4x. I guess PC800 40Nns is not the same as PC1066. So i'll get that later when Mushkin and Corsair come out!

Hope this helps!
