jhites, you're using the house brand RAM in that system, right? Is that pc4000 or 4200?

BTW, I have the 2.8C MO running at 242FSB, turbo and pat enabled, 2.5-3-3-7.

AsusProbe shows "Max speed 3600MHz", does that mean anything?
 
It means your CPU is running @3.6ghz. But that doesn't make sense since you're running a 2.8 CPU @242mhz bus which is 14 x 242 which is 3388mhz. Maybe the Asus Probe can't work for CPU's above 3600mhz/3.6ghz?

John's memory is a "house brand" that uses Hynix chips, but I can't recall if it was 4200 or 4000.

As for your USB Dave, good question. Are they both USB 2.0?
 
kona, I don't think those numbers are the voltage ratings. USB+5V is the positive pin, where the red wire connects, for port 5.
The headers are there in case you need additional USB ports or for front panel connectors.
 
computer, the information tab of AsusProbe has the "Current speed 3406MHz" and "Max speed 3600MHz". Just wondering what the detected "Max speed" is on your 2.4C.
 
Even the "3406mhz" speed doesn't make sense, that's still not 3388mhz which is what it would be if indeed you're running a 242mhz bus with a 2.8C 800mhz bus CPU. I don't have the Asus program installed on mine right now, I just started it up and checked. Guess I didn't install it 2nd time around. Temporarily change your bus and see if that changes the #'s in the Asus Probe. I can install mine again when I get a minute.

Yes, it is the house brand PC4000 from Hardcore Cooling. Just because the fsb is set to 242 in the bios does not mean that is the actual. Most of the P4C800 boards run 1-2Mhz higher than what is set in the bios (ie: 242=243/244). For a 242Mhz setting in the bios 3406Mhz is about right for this board. Asus has always done this to try for a little better comparison test with other boards. 🙂 The Max Speed indicator in Asus Probe is a cpu indicator that shows what the processor max range is supposed to be capable of achieving and not the actual speed that the processor is currently running.

edit: My 2.8C MO also shows that same Max speed 3600Mhz in Asus Probe.
 
computer & jhites:

i'm back again. 🙂 thanks for the help before, but i have another question.

as a refresher:

3 weeks ago i got a 2.8C, 2x256 Corsair PC3200 (XMS C2s, not the TwinX LLs and not matched pairs). On another forum I asked about lowering the memory timings and trying memtest out. i was advised to:

--

- Set the FSB to 210 and MEM to 400
- Set AGP/PCI to 66/33
- Set VCORE to 1.525
- Set VDIMM to 2.55
- Set VAGP to 1.50
- Set the PERFORMANCE MODE to STANDARD
- Set USE SPD SETTINGS to DISABLED
- Set the timings to 2-3-3-6 (BIOS order)
- Set PERFORMANCE ACCELERATION to ENABLED
- Boot a MemTest86 floppy and let it run for at least 2 hours.

If OK, repeat test with timings = 2-2-3-6 (BIOS order)

If OK, repeat test with timings = 2-2-3-5 (BIOS order)

If OK, repeat test with timings = 2-2-2-6 (BIOS order)

If OK, repeat test with timings = 2-2-2-5 (BIOS order)

Use the timings that passed, with FSB = 200 instead of 210 and you will have the best performance setup with maximum component durability/reliability. Overclock at your own risk.

If you want some eventual extra performance, set MEM to 320 (actually this means that your memory will run at 4/5 of your FSB, and not the real memory speed) and FSB to 225 & up. At FSB = 250 your memory will be again at 400MHz but your CPU will be running at 3.5 GHz instead of 2.8.

--

so i set the settings and Memtest crashed - every time. it gets to about the 4th test and just sits there. i have to reset or shut it off. and usually i get a "Overclocking failed!" response when I reboot.

i've tried running Memtest with:

1 stick at a time in each slot
2 sticks dual channel
2 sticks not dual channel

i even took those 2 sticks back and got new RAM (from the same place and the same model) with the same problems.

no go. i'm not having any problems with the computer - but it's really bugging me that I can't get through a Memtest without it locking up. i even try NOT OVERCLOCKING and it's locking up.

so yesterday I bought another 512 of the Corsair to give me 1GB total (not to replace the others, but to complement them). When I took them home, I realized I got the LLs (this time i got a matched pair). so i now have:

2x256 C2s
2x256 LLs

both running in dual channel

I put them in, set Overclock to 5% and it posted! before, it always failed whenever I tried to use the "Auto overclock".

So i bumped it up to 10%, and it posted again. Checked with CPUZ and I believe it said i was at 220MHz @ 10% (but I can't remember the memory timings.. 2-4-4-7 or something at 5:4 i think). I watched the Asus probe utility temps (on one monitor) while I played a heavy round of Unreal Tournament 2004 and watched the CPU temp shoot up to 114 F from 85F and it stayed under 120F with the stock HSF.

now, my questions

1) what the heck is wrong that I can't run Memtest without it crashing, even when i'm not overclocking

2) is that temp OK for extended periods of time?

3) i probably shouldn't have mixed and matched timings because it'll use the loosest timings right?

tonight i'm going to try Memtest with just the 2 LLs in dual channel with the memory settings suggested above, unless you have any other suggestions.

thanks guys.. this is frustrating!

try turning off usb in the bios and run memtest and also go to MemTest86+ if you are not using this version.

2) is that temp OK for extended periods of time?

that temp is OK for load. 46C is pretty normal for stock cooling under load.

3) i probably shouldn't have mixed and matched timings because it'll use the loosest timings right?

Your timings will be whatever you set them to in the bios when using manual settings for all sticks. There may or may not be some issues since the spd timings on the sticks are different.

tonight i'm going to try Memtest with just the 2 LLs in dual channel with the memory settings suggested above, unless you have any other suggestions.

Definately use manual timings with those LL sticks. The default for auto on the board is 2.5-4-4-7, I believe. That will most likely cause problems with those LL sticks. I would also suggest that you set the vdimm to 2.85 volts.

the auto SPD settings are currently 2-3-3-7, according to CPUZ.

i tried a single LL stick (before you posted this) and i'm still having the same problems. i'm going to try your suggestions now..
 
good news: disabling USB worked for Memtest - thank you! i ran through for about a half an hour, and all seemed well. i'll test more later.

bad news: it's failing to overclock. i tried with all 4 sticks, then went down to just the 2 LLs (which are rated 2-3-2-6).

here are my settings:

CPU External Freq: 210 (or 200, neither work)
DRAM Freq: 400
AGP/PCI: 66.66/33.33

CPU VCore Voltage: 1.5250v
DDR Reference Voltage: 2.85v
AGP VDDQ Voltage: 1.50v

Performance Mode: Standard (or enabled, neither work)

--

CAS Latency: 2
DRAM RAS# Precharge: 3
DRAM RAS# to CAS# Delay: 2
DRAM Precharge Delay: 6
DRAM Burst Length: 8

Performance Acceleration Mode: Enabled (or standard, neither work)

anything i'm doing wrong?

ack.. i forgot the BIOS order is wrong. i'm running at 2-2-3-6 (BIOS order) and it looks like i'm fine at 1:1.

now, if i wanted to overclock, should i follow the advice given on the other forum as i posted above?

I would just start increasing the cpu speed in 2Mhz increments. Assuming that you want to keep those timings, you may find that you reach your peak quickly. Especially, using 4 sticks which are not optimal for overclocking.

 
I've been reading some comparisons between the old Raptor and the new Raptor (WD740GD) and something confuses me. I know the old one didn't have tagged command queuing, but the new one does have it (TCQ). The reviews comment though on a controller not being available for TCQ, so what's the point in having it? Does anyone know if the P4C800-E Deluxe supports TCQ on either the ICH5(R) or Promise controllers? (BTW, the new Raptor smokes the old Raptor, in fact it even beats 15k RPM SCSI drives in all except multi-user server tests). Obviously what makes the new one faster is something else besides TCQ. Buffer is the same, RPM is the same, areal density is the same, so it's something else that makes it so fast.
 
Have you figured out how to get the Intel SATA controller to show up when booting? As yours, my Promise controller finds not drives but the SATA1 ICH5 doesn't even see my SATA drive!

Kind regards if you have any pointers..
 
I got that same 'chipset not supported error'. Are you really required to install the IAA (which version) during the f6 intallation prompt?


How do you set your BIOS settings to get P4C800 Deluxe to even recognize my Seagate 120 GB SATA drive?

It saw it once.. I RMA'd the drive.. got a new one and it STILL does not see it. Read manual, installed Intel's latest configuration utitility, etc.

I'm NOT running RAID, I'd just like to connect one SATA HD to SATA1 (I'm told controlled by Intel ICH4 875P chipset) that's all and it does not see drive. Drive is alive as it makes noises as if searching and it is connected properly..

ARE THERE JUMPER SETTINGS on drive that I am missing? I'm told Seagate SATA drives do not have jumpers.

I've tried Enhanced, Compatible, S-ATA, P-ATA + S-ATA, etc. under IDE CONFIGURATION (manual says to leave it at S-ATA, Enhanced) for XP Professional systems.

Enable or Disable Promise controller in BIOS as it never sees my drive anyway when I am booting up. How do you get a fresh SATA hard drive to be seen by the BIOS?

I've tried to hit CTRL + F on boot-up, F2, etc. and I can't get into any of the BIOS utilities.. I cleared CMOS and removed battery to start afresh to see if it would see it.. nothing.

Did I not install 3rd party drivers on the F6 prompt when installing XP?

What are the steps when installing XP to get the P4C800 Deluxe to 'see' the drive with exactly what drivers and when to install? Drivers are installed in my Device Manager so it should see it. No yellow question marks.

Kind regards if you can offer any suggestions..
 
lament I never heard of having to disable USB in the BIOS for Memtest to work. Legacy USB, yes, that should be disabled, but I never heard of ALL USB being disabled. A few days ago I did some memory tests and benchmarks using 4 sticks instead of my two, and new two were OCZ Gold. I did this for the heck of it since I knew odd things may happen mixing two different memory brands. For one, the max O'clock was only 265mhz compared to 281mhz with Geil alone, and 288mhz with OCZ alone. Also, these were all 256mb single sided modules, yet PAT would not work!! What's up with that? Why would PAT show disabled with 4 SINGLE sided sticks?? I heard it gets disabled with DOUBLE sided, but not single sided. Could be PAT became disabled due to the sticks not being matched. ??

Usually using 4 sticks, even matched, will not give you as high of an overclock. Many times, 4 sticks of even matched memory will not overclock as much as a single Dual-Channel kit since it's very hard to perfectly match in every way 4 sticks, and Dual-Channel kit forms unfortunately do not come in 4 stick sets, only 2. This makes upgrading by adding another DC kit not a very good option. For the best results, if one wanted to go from 512mb total to 1gb total, you'd have to get the 1gb kit and "eat" or sell your 512mb kit.
 
surrendered, the IAA will only install if you have a RAID array installed. I haven't tried it, but it may work if you you setup RAID in the BIOS temporarily, then install the IAA, then go back to the BIOS and set it back to IDE instead of RAID. Has anyone tried this?

I never had any problems installing an SATA drive. I posted details on it in this thread somewhere, see if you can find it. The bottom line, is you're not going to get anywhere until the BIOS sees the drive. If it's connected to the Promise controller and it's not being seen in the Promise screen BIOS, then something is wrong somewhere. Then and only then will you be able to install it once it's seen in the BIOS. Also, it's best to let the HD's CD format the drive first, once you get it to be seen in the BIOS of course. If you let XP have to format it, that's when things can be more difficult and take longer.

Try another cable. Since the HD is new and the second one you've tried, it's probably safe to say that's not the problem. Could be a bad mobo. See if the HD can been seen on the ICH5 SATA controller. I don't know why you see, or say ICH4, this mobo uses ICH5(R). I think in the first BIOS screen at the bottom of the drive list is some kind of "IDE configuration", sounds like you've been there. All I can say is to set that "configure SATA as RAID" to "NO" which you may have already done. That "Enhanced mode support on...." cannot be set to include PATA if you want to boot from an optical drive. So, when you boot from the HD maker's CD or XP CD, that must be set to "SATA" only.
 
Hello All, new to this forum. Scanned through the posts on the P4C800-E Deluxe and didn't catch anyone having similar problems as I have. What is going on is the system will freeze at no particular time or processor temperature. What I have for components - P4 3.4 ghz with hyper threading, 2 gb of Crucial ram, 500w power supply, Asus radeon 9800 xt video card. There are 2 maxtor 120gb SATA hard drives. The video card is the only thing installed on the mother board. I have updated all the drivers, and the bios is 1016. I am running windows xp professional. The system runs awesome when it is working, just freezes up and nothing will respond, not even control-alt-delete. I have to press the reset button and it restarts. When it does freeze, the display stays where it was, doesn't go black, but my optical mouse light goes out. Which tells me something is going on in the motherboard, but I am getting no help from Asus. I have read about this problem in other forums but no one seems to have a solution. Some have brought up that the hyperthreading is causing issues, I did download the chipset drivers direct from intel and tried them, but still no help. Sometimes it will go 24 hrs and run fine, other times it will do it in a couple of hours.
 
Is the entire system freezong, or just you mouse.

If it is just your mouse, and you are using Logitch drivers, I had a similar problem and had to deactiviate fast initialization in the mouse properties.
 
Its the entire system. Screen freezes at the whatever point it was at, nothing moves. It is a microsoft mouse. Screen will stay at its frozen position till the reset button is pressed. No error ever comes up from windows, that why I believe there is something going on with the motherboard, possibly needs a bios upgrade. Have notified Asus, but no response.
 
I am using the intel heatsink, but don't think its a heat issue. I have an alien case with two temp sensors. One is placed on the cpu, temp stays around 29-32 deg most of the time, unless I playing a game. Computer freezes a lot of times just sitting having nothing opened but email. What is strange though is after it freezes the cpu temp climbs up, possibly because the fan isnt controlled by anything anymore? It is aggravating because I love the way this motherboard performs, this freezing up just stinks.

What do you mean by the fan not being controlled anymore, does it slow down or stop? How high does the temperature climb? What is it after you reboot? Just wondering, how do you know that the temps go up after it freezes and not before? I'm not familiar with the alien case temp sensors or how quick they respond to the change in temperature.

Was the heatsink hard to lock down? This board has an issue with the Intel heat pad. I've tried two other P4s with no heat pad and had no problems buckling down the hsf unit. I broke the plastic tab when I tried to lock down my 2.8C with the pad.
