Question about ASUS P4S800D-X Motherboard

1 Answer

Need to find timing and voltage on my memory to make correction to stop overclocking failed, need help please.

Hey there everyone I have call Asus company and ask them about the overcloking faile. They said its because of my memory. I have to find out the voltage and the timing of the memory and then make correction in bios.
I went online to check out the website on corsair vs512mb333. What I found is the voltage is 2.5, but I can't find the timing but instead I found latency 2.5-33-7-2T. The tech says to find timing and voltage and go to the bios and make changes to fit with the memory. How can I do that? I call Fry's electronic and they want to charge me $70 and BestBuy $59. Can I do this myself? Can anyone show Me?

    the corsar vs512MB 333 CL2.5 will function in your board.

    Use your manual incert your memory into DIMM A1 (blue) & DIMM B1 (blue). Set everything in your bios for memory to Auto.

    You will never see the difference in preformance by over clocking your memory. Want to increase speed run 4GB of PC3200 CL2.5 Dual Matched memory. That will kick it in the pants.

Mobo Compatibility and tech/spec variations

All Asus P5GC-MX/1333 mobos are "X-series" boards.  

If you put higher speed ram on that mobo, it will just run the ram at lower speeds.

The board will not take 1333 speed DDR3, because it is only DDR2 compatible.

OVerclocking is complicated and risky, here is neither the place to teach or learn overclocking.

Some newer core 2 chips will automatically overclock, when all but 1 core is in hibernation (which will never happen if you are using vista). Other than that overclocking involves setting the bios to increase the memory buss speed, as well as slightly increasing the cpu and ram voltages as needed for stability. There is a great risk associated with manually overclocking and adjusting voltages, and should not be attempted by beginners on machines they value.

Overclocking FAILED

This could be a number of things, memory, video card, communication promblems, I suspect its the voltage droping below the tolorance if it happens every once in a while. I would try plugging into surge proctor first.

I am trying to add (2) KVR400/1GR to my ASUS K8V-X motherboard. They register fine but run at 169 hz not 200 hz. WHy is that? Can I force to run at 400?

Kingston KVR400 MHz memory will not run correctly on your Asus MB.
The bus speed of the MB can't handle over clocking memory to 400MHz Just because the CPU can handle 533/400MHz doesn't mean the memory can. You should be able to over clock the PC2100 memory up a bit to maybe 276MHz. Personnaly, I wouldn't even try it. Overclocking the CPU is much safer. Even if your board could run 400MHz memory, I doupt you'd even notice the higher data transfer rate.
The Asus P4V533-MX only supports, 2 x 184-pin DDR PC2100 / 266MHz or PC1600 / 200MHz non-ECC memory. Thats why your memory was lowered by the bios to 169MHz.
You would have to raise the voltage and speed on the memory. Odds are you'd fry the memory if you do so.

Hope you find this helpful.

Overclocking is set from the BIOS configuration. Not all BIOS allows overclocking, it may need a BIOS upgrade.
Check the ASUS WEB site for your model motherboard.
Overclocking the CPU (ie running at a higher clock speed) and increasing Frontside bus speed will give better performance BUT there is a downside too, if you overclock too high you could overheat the CPU and it could fail.

Asus Maximus Motherboard memory problerm with Corsair Dominator 1 GB DDR2 x 4

Hi XaaX,

Sorry to hear about your troubles. I have built over 100 machines using ASUS MB's and I've never run into a problem like yours. I'd suggest that you check a couple of things: 1) Make sure that all your BIOS/clock settings are correct, not just the memory frequency. As I'm sure you know, you need to check the CPU settings (voltage and clock speed), FSB settings, memory settings, and voltage settings, as you could be overclocked without knowing it. Also on overclocking it is sometimes a bit of luck of the draw, as some CPU's out of the same batch will overclock 20% or more and some will not overclock at all (if you haven't read about how Intel and AMD decide what speed to market the CPU's at as they come off the line, you should; I think you'd enjoy it!). The second thing I'd do is to get memtest (you can Google where to download). Make sure you get the version that runs at the system level, not the version that runs inside Windows. It is free. If you let it run for a couple of hours, it will tell you EXACTLY what, if anything, is wrong with your memory.

In any case, you should be able to run any ASUS board at 100% of factory specs and never have a HW related crash. If you can document your saga to ASUS, I'm pretty sure that they will MRA the board for you, assuming it's still in warranty.

I hope this is helpful. If you think it appropriate, I'd very much appreciate a Fix Ya rating on this solution. Good luck!

It sounds like you're trying to overclock your CPU, and you have exceeded what the CPU is capable of, under the current conditions. When you start the computer, enter BIOS setup (e.g. press the DEL key), and adjust the CPU settings to default. If you're not sure how to do this, choose the "LOAD OPTIMAL SETTINGS" or "LOAD DEFAULT SETTINGS" option from the main BIOS menu. If you are not getting this error until after Windows has started, then there is software installed that is trying to overclock the CPU for you. Uninstall it. It may be a program provided by Asus, or may be a third-party program. It will probably have "tweak" or "overclock" in the name. Overclocking can achieve an increase in performance, but will void the warranty, and does reduce the lifespan of the parts, and tends to make Windows crash more often. It can cause immediate failure of the parts. It should only be done if you understand and accept the risks, and have decided the reward is worthwhile. For most users, it is not worth it.

Overclocking failed

Hi, If you have overclocked: 1. CPU or motherboard not up to it - run at default speed; or 2. Memory - try using other memory; or 3. Video Card - see if you can run the Video card at default speed and not with overclock speed; or 4. You may need to up the CPU B+ a bit. If not overclocked: a. Set BIOS/CMOS to default settings; or b. Disable any overclocking feature (even if not used); or c. Lower you CAS latency. Hope this be of some help/idea. ood luck and kind regards.
