After reading all the great reviews/bench results about the P4T533, I placed orders at NewEgg and GoogleGear this morning.

Later today I found this little thread - Asus P4t533 w 4200 rimm arrives ! ("only" 33 pages so far)

Reading a 33 page-thread might be a bit too intimidating, so I'll try to make it simple. Oh and before I go for it, let me tell you that I was going to cancel my orders after reading those 33 pages. And guess what? My orders were already processed and couldn't be canceled (I wanted to kill myself cause I asked for rush-processing). That being said, according to many (or everybody except those at benchmarking sites) in the thread, this board is turning out to be a nothing but a garbage. Below are the foundings from them. All the symptoms didn't happen to everyone, but we could draw a big picture from what they've gone through.

1. The board doesn't function well/at all at its stock FSB speed (133Mhz). Sometimes it doesn't even get you to the POST screen.

Possibly the most ridiculous event in the motherboard history. What the **** is ASUS doing here? Almost all users are reporting system/testing failure at FSB 133Mhz. I thought they're joking at first, but they weren't.

2. It's almost impossible to find a stable FSB on this board.

Symptoms vary. A user says he was able to run the system stably when he overclocked from 1.6 Ghz to 2.4 Ghz, while another users says he had to "underclock" his 2.4 to 2.0 for stable running. Here is a quote from a user.

The problem is that today it may fail at 165 and 167 and run ok at 166, but tomorrow after the room temperature changes a few degrees you'll find it may pass at 165 and fail at 166 and 167. Do you want to be testing for the "stable" frequencies all the time?? I can take a small fan and blow a little air on the ram area and move the stable and failing frequencies. The only frequency I found I could really run at was 172X3, since when I first tested I found that 171/172/173 were stable and 170/174 failed. The next day 173/174 were failing. 172 still worked since it started out in the middle of 3 "stable" frequencies and the failing frequencies hadn't "drifted" down to 172 yet. Being able to work at "one" magic frequency isn't what I call acceptable. Heck it's not even stable at 133X4. If people still want to keep buying this board and ram then fine, that's their business. Anyone that's aware of this thread and still buys the board and ram has only themselves (and ASUS) to blame if/when it doesn't work reliably.

3. Some users reported the instability of the motherboard when used with nVidia's graphics cards.

Would you believe this?

4. Stability issue with the new 32-bit modules

A recent founding showed the modules used for all the benchmarking prior to the board's release to the public were all ECC-rams. And this type of rams are not currently available on the market. In the meantime, many online retsellers are selling non-ECC modules bundled with this motherboard. It seems obvious that Asus knew about this, and I don't know how they're gonna deal with this. Other problem with the memory is with the FSB. Since the default FSB isn't stable, people try to find a stable FSB for their boards (At this point, "how high can it go" becomes meanigless). And of course it causes problems on the rams.

arghhhh.. I'm so angry and can't believe I didn't find this thread while I searching before ordering. Anyone with this board, please post your experience or fix information here. My packages will be here this Wednesday... :(

Well I just saw the thread a few lines below and here everybody seems happy with the P4T533?? I'm so confused.. Can anyone share the experience in detail? Like I said, my board is coming on Wednesday... :eek::frown:

Usually with any new hardware/technology you just have to try it out and see what happens. In this case it could cost you time, headaches and maybe money.

I?ve not used or have any thoughts about building any more systems based on RDRAM. Not since my second RDRAM system (Abit TH7-II), and I have no intentions of building any future system based on RDRAM (unless the SiS 658 proves to be super exceptional).

One thing to consider is that a lot of them over at HardOCP forums are overclocking to some extreme fsb?s.

If this board is having problems running at stock speeds then I would be very concerned!

I woudnt bother with those error u found on the forum. Asus produce quality board. Since you couldnt cancel your order, why not give it a try? be optimistic ! Try everything on default, no overclocking until u find out everything is fine on default. Read the menu , specially the ram part. Check is there any update bios ... one of the saleman from retail store have this setup, and his mobo is running fine. SO not to be so worried ..... ppl always told me not to get a abit mobo because abit mobo seems to have lots of trouble ...but from celeron 366 to p3 1 ghz i am still using abit mobo SA6R ...BH6 ....be62 all abit mobo running fine on me. good luck !

From my experience, albeit a very limited one, Asus motherboards are great products and if there are problems with it, they usually fix it in a bios update. Don't give so early man, I'm sure a bios update will be posted up soon :).

I have 2 P4T533 rev 1.03 boards running since 2 weeks and a total of 5 (256MB) RIMM 4200 moduls:

(a) there is no stability issue whatsoever with both boards
(b) maximum FSB in x3 is 179 Mhz which brings my 2.26 to 3043 Mhz, aircooled
(c) maximum FSB in x4 is 168 MHz
(d) maximum achieved bandwidth is 4500 MB/sec, that the highest bandwidth I have ever seen. A real killer board.

I have not found a single issue with this board so far. The following I would critizise though:

- the layout could be better
- Vdimm voltage would be good (can be modded though)
- the BIOS 1.02 is HORRIBLE, but all problems were solved with 1.03

Regarding the stabililty of the RIMM 4200 moduels: as I said, I have 5 of them, and have tested them all with RAM testing software:
goldmem, docmem, and memtest86. All of them (with 1 exception) are 100% stable and fault free at 160Mhz MHz at 4x and 170Mhz at 3x.
Like any other RAM they start to produce faults when you push the envelope to the maximum. But even at 179 MHz I can still boot into Windows and can take benchmarks.

Probably some ppl who complain about 170 MHz, have no experience with RAMBUS. This memory is not like DDR which have to push insanly high to get a reasonbale bandwidth. Rambus delivers at low frequencies.

Well I didn't get the parts I just built the computer, The guys son-in-law gave him the processor and memory, Other parts from Newegg, I ask him about it and he said he would talk to his son-in-law but I haven't heard from him on it,

Where did you find 512mb R-4200 modules?

I believe there is no 512 R-4200 released to public yet.

What he has is only 256Mb modules

First of all, thanks for all the inputs, guys.

I finished building up my new system (2 days ago) with this board (P4T533), and it was overall successful. I'm saying "overall", partly because it was my first try to build a system on my own, and partly because I had a similar issue that other people seem to have. (at hardforum(?).com, link at my first post)

Speaking in short, my system wasn't stable at FSB 133MHz (!). CPU is 2.26B, and got 2 pieces of 256Mhz RIMM4200. I booted the system, and installed the Windows XP, then upgraded the bios to the version 1.03. XP installation was successful, and I toyed around with XP for a bit (with updates and sh*ts), and installed WC3 and played it a bit. Things looked OK to that point. I did sandra which gave me just about the right score for the specs. Then, I ran Prime95 - and nightmare began.

My Prime95 test failed within 10 mins. I tried like 20+ times - normal one and torture test, results were all the same. It always failed within 2~10 mins. At the last try of torture test, my system crashed and auto-rebooted (I was almost panicking). I changed the FSB to 134MHz, and my machine runs like a charm. Prime95 has been running for over 24 hours, and the Asus PC Probe says everything is fine, and my CPU temperature is around 40C (100F?). Just to let you know, when I had FSB at 133MHz, I had the memory clock at x4 (manual), and turbo RDRAM enabled. I still have the same settings for 134MHz FSB, but someone at hardforum mentioned it's better to leave the memory clock setting at "Auto", and disable the turbo ram thingy.. can someone confirm this?

I may try overclocking a bit later, but it looks like gambling to overclock with this board/ram combo.

Thanks!

And a quick newbie question for you.

What does Prime95 do? (I just ran it although i don't know what the h*** it is) I'm asking this cause my system was ok with other bench/testing programs EXCEPT Prim95.. Does it do anything special?? Also, what's the difference between the "standard" test and "torture" test and what are the acceptable results (in terms of stability), respectively?

OK, guys.. I really hate to say this, but I'm just about to break this system..

This motherboard/memory (P4T533/Samsung RIMM4200) combo doesn't work for me. I've been struggling all weekend, and it's a waste of my time. I'm going to call Asus as soon as they're available on the phone, then decide on either replacement or refund.

Sadly, my system turned out to be extremely unstable. I thought I passed the Prime95 for 24 hours, but it was my mistake that I didn't catch there had been one error in the middle and the test had restarted. I tried the Torture test, it fails within 2~3 mins everytime. If I put the test on loop, it causes the system crash or froze within 30 mins. Just to make sure, I'm NOT overclocking the CPU at all, leaving everything at "auto" or "default" by the BIOS. I once had the FSB at 134MHz, but it couldn't pass the Torture test. In fact, it couldn't even start it. So I changed everything to auto/default.

It's really mysterious for me cause I can't seem to find out why. Everytime I test I leave the Asus PC Probe open, just to check the system's condition. I don't know how accurate it is, but everything looks fine from the information it gives. For example, idle CPU temperature is around 32C, and max CPU temperature is somewhere around 40~44C, which I believe to be pretty normal. It doesn't give me any warning before the system crashes or the OS freezes.

Only thing I tried other than the default is setting the FSB at 100MHz, which turns my CPU to be a 1.7 GHz one. Surprising, then it looked ok while torture-testing. However, this is absolutely not acceptable cause my CPU is marked as 2.26GHz. I paid for 2.26GHz CPU, not for a 1.7GHz one.

I know there are other folks have good experiences with this motherboard/memory, but I guess I'm just not that lucky.. :(

I may try replacement before return (damn things are so expensive and I really don't want to pay for %15 restocking fee.. I'm so poor.. :( ) with the new ones, but at this point, I'd like to ask other users with experiences of this mobo/mem combo. Has anyone tried the Prime95's torture test on your system? or CPU Stability Test? or, Sandra's Burn-in test? was your system able to keep running for at least 24 hours??

Desparate,

lopri

Have you tried setting your Rdram settings manually (4X) and not on auto? And make sure you have the latest bios, 1.03 or something like that is the one you want, not 1.02. Just a suggestion, since I read at Asusboards.com that some people had to do this to make their rig stable and also put the jumpers to 134 instead of 133 (but of course you said you tried that). If this doesn't help then I'm out of ideas, sorry.

Just called the NewEgg & GoogleGear and got RMA #'s for the board/modules. Enough of wasting time...

Sadly,

DId u try increasing the voltage, i know this guy had similar problemw ith defaults, he needed to increase voltage and it was fine.
