Angry Asus P4C800 Deluxe crash problems

A few months ago I upgraded my system to a P4 3.0C, Asus P4C800 with two 512 mb PC3200LL TwinX modules. Despite a warning that the PC3200LL was incompatible with the board from the place I bought it from, it ran great for about three months. Now I get random crashes all the time for no reason whatsoever. Seg faults, the whole system shutting itself off all of the sudden, every error under the sun. There is no discernable pattern, nor a certain amount of time passes before they occur.

I have tried many different BIOS settings that I have read as recommended in this forum (with the latest BIOS as well: 1010)

I tried another memory module: 1 Corsair 512 PC3200 CAS-2 CMX. With both types of modules I get a hefty error count in memtest.

It cannot be as a result of the OS (I have reloaded & reformatted windows XP pro several times and Linux 2.4.20 only has slighter problems due to better memory management :) ). It cannot be another piece of hardware, I have tested the memory and tried running my system with basically nothing but a graphics card and a hard drive (different working hard drives, as well).

So, to sum all of this up, I am really fairly certain that this has nothing to do with my RAM. However, the warning from my retailer that the RAM modules I had purchased were not compatible with my motherboard still linger in my memory. My question is: Does anyone have any other ideas before I scrap this motherboard?

I am sorry that you are having trouble, But can you tell me a few more details about your other hardware like the Make and model of PSU you have and the CPU speed you have installed and the Video card you have?

Default exact same issue

I have had *exactly* the same issue with the ASUS P4C800-E Deluxe, except I started having problems after about two weeks. Using the TWINX3200LL as well.

Initially, everything was perfect. Good os install, perfect app running, everything seemed smooth (and sooooo fast!), but then the bsods started (winxp pro). I tried every possible combination of memory timing, to no avail.

So, I rma'd the board and got an Intel D875PBZ. Upgraded the bios to p09, so it would see the ram as actual DDR400, and set the latencies at 2-3-3-6. Couldn't installed windows without crashing. memtestx86 showed numerous errors after running for quite some time. I then clocked the memory bus at 333mhz, and was able to install XP, however I *still* get oddities and memtestx86 issues. Even setting the latency at 2.5-4-4-8; doesn't help. Tried dropping the memory bus to 266, and still no joy.

Tomorrow I try testing each module one-at-a-time to see if I can identify where the problem is. The very interesting point is that with the ASUS P4C800 I had NO problems for two weeks. I'm wondering if the higher-than-spec memory voltage on the asus could be responsible for the damage? Now, I never *set* the voltage high on the board, but I've read in a couple places that the p4c800 bios misrepresents what true voltage is being used.

Regardless, I plan to rma the corsair modules, but I need to wait until I can purchase replacement memory (can't be without a box). I think I'll go with the "vendor approved" Kingston modules for the Intel board, as I have just read about too many horror stories with corsair and i875p chipsets.

You really need at least a 400 watt PSU with this combo of hardware. I would suggest testing the memory one module at a time on another MB if possible with www.memtest86.com.

I will try a new PSU then. It is close to three years old and I have quite a few devices: 1 AGP, 4 PCI, 4 IDE devices and 8 fans. I suppose that could be a significant drain on my power.

Thanks!

Please lety me know and we will be happy to replace the modules if needed. But I would try testing them on another Mb if possible first.

Exclamation TWINX1024-3200LL on Asus P4C800-E Deluxe

I think I may be in the same boat. Here's the system I'm running:

Power: Thermaltake Silent Purepower 480Watts
Motherboard: Asus P4C800-E Deluxe
CPU: P4 3GHz, 800MHz FSB
RAM: TWINX1024-3200LLPT 1GB DDR400 XMS3200

OTHER Stuff:
Video: ATI Radeon 9600
Audio: SoundBlaster Audigy 2
Other PCI: old TV tuner card
Hard Drives: 4 IDE disk drives
Optical Drives: 1 CD-R/RW, 1 DVD
Fans: 7 case fans

My problem: For the first couple days I had my new system put together, it ran perfectly with Windows XP Professional. Then, yesterday it started freezing. At first I thought it might have something to do with Windows power management or problems coming out of standby. So, I disabled all of that. Moreover, it freezes at random. Additionally, on some of the boot ups the motherboard beeps twice, signaling a parity error. But, it doesn't always do this.

I'm running Memtest86 as we speak, and we'll see if it reports any errors.

Does it seem to be the case that this RAM and Motherboard simply don't work together? Any advice on what I should do? Should I tweak the settings in the BIOS? Upgrade the BIOS? Move the RAM from the blue channels to the black (though I plan to add another GB when I can afford it)?

Thanks in advance for the helP!

andrew82, Please test the memory with www.memtest86.com, But I think you may find the issue is with your Creative card and or the TV Tuner card. for this MB the PCI card should be PCI 2.1 Spec. If you get errors I would remove all of the cards and then please try setting the timings to BY SPD and set the Dram Voltage to 2.75 Volts and I would Disable USB legacy support as well.

Ram Guy,

I checked and the Creative Audigy 2 sound card is PCI 2.1 compliant. It could be my TV tuner card, which is a piece of junk.

The Memtest86 has been running for over 11 hours now. How long is the thing supposed to take?

Could you elaborate on what you mean by "setting the timings to BY SPD"?

Once the Memtest is completed, I'll take out the TV tuner card and make the "BY SPD" and voltage changes. Hopefully that's all I need to do!

Well www.memtest86.com will not stop untill you stop it. Its made to do nothing else but test/stress the memroy.
If there are no errors listed on the bottom of the screen then I would think the memory is fine especailly after 11 hours.
I would try the system with out the PCI crads installed and make sure there are no drivers loaded for the on board sound and see if the system is stable with out the cards in the slots.

:)

My board is a Asus P4C800 Deluxe and i use two pairs of 256mb
Twinx 3200LL
The board runs with no problem settings are 2-3-3-5-8 and
i set the voltage to 2,75volt as Ram Guy says.
PAM is enabled and Performance mode is set to Standard.
I noticed that the ram sticks are rev 1.2.Have the Twinx 3200LL
sticks been upgraded Ram Guy?
Im not a mad OC so i'm happy with my rig.But i have only had it
for a week.Lets hope it keeps up the good work.

Default Parity Issue - Cause = ?

OK, so I took out the TV tuner card and was still having problems. I found it highly unlikely that the top of the line sound card was causing my problems. So, I decided to go ahead and wipe the hard drive and start all over. That has seemed to solve the problem of system freezes. I decided not to put back in the TV tuner card and not to install my parallel port zip drive in case either of those were causing the problem.

However, after intalling Office XP (and this may very well be a coincidence, since I can think of no logical reason for this) my motherboard began reporting a parity error upon boot up. I thought, "ah ha...now I'll catch the RAM error" and went and ran another memory test with Memtest86. But, after 8+ passes it didn't find anything.

So, what could be causing my motherboard (see above posts for specs on my system) to report a parity error? Should I worry about it? Surely it's not linked to Office XP.

What it's telling you is that you have a parity error? Are you just getting 2 or 3 beeps? If so the USB controller will give a beep for each device connected and sound like a parity error that the manual describes. Please try disconnecting any USB devices to test.
