Upgraded computer; Now all my games crash!

CPU Clock Frequency = Default

what other choices do you have?

According to the BIOS update (yes I remember these numbers in CMOS):

.ADD CPU FSB TO DEFAULT/50/66/75/83/100/103/112/133 FOR ALL KIND OF CPU IN CMOS SETUT. <-- haha typo!


I already tried 100 just to be sure, but it still crashes. Did that help?

Holly found a pdf file for the motherboard.

Try setting your CPU/PCI Clock (CPU Frequency Clock) to 83.3/41.65 if that's available.

Then your CPU and PCI/AGP slots should be running at the right frequency all along!!

Jordan: I did try 83 Mhz as noted in my earlier post. It sets my CPU to 500 Mhz. Do I need to change something else beside CMOS' clock freq?

Did I mention this is my second CPU?

Please check the max CAS speed of you memory, for I think you have to set it higher (4 orso), as it's 100 MHz memory !!

Jordan: One problem. I can go use 2 or 3. CAS Latency timing also has Auto (already tried this). =(

OK, the .pdf file that I have is the manual for Rev. D which board neither one of us has or had, but there was no manual available for Revision A on the DFI site.

So the information is not exact, since one of the things revised was the BIOS. But the manual for Revision D of the board does say that the AGP clock should be set automatically by the FSB, and the "Default" setting of the "CPU clock frequency" menu item (in Revision D called "CPU/PCI clock (Mhz)"--at least in one screenshot, in a later one it appears as "CPU Clock Frequency" *sigh* ) takes the FSB from the CPU.

So in one respect, it would seem that you don't need to change the AGP bus ratio, but the fact that the system runs more stably at a lower FSB does imply that something on or attached to the motherboard is running at the wrong speed.

So I do wonder if we are back to the "bad stick of RAM" thing.

I would suggest running at 100Mhz with only one stick of RAM and then with only the other. This will be pretty tedious, because the most thorough way to do it would be to try each stick of RAM alone, in each of the DIMM slots.

<font size=5>HOLD THE PHONE!!!!</FONT>
YOU HAVE JUMPERS TO SET THE FSB!!!!!

from the manual (hey if the jumpers are present in Revision D, they're surely in Revision A, right?):

Hardware Installation
2.3 Jumper Settings for CPU™s Front Side Bus
Positionnement des cavaliers pour le bus frontal du processeur
Jumpereinstellungen fuer CPU Vorderseitenbus

Jumper JP3
CPU™s Front Side Bus Select
The default setting of jumper JP3 is Auto - the system will automatically run according to the FSB of the processor. If you wish to overclock a 66MHz FSB processor to 100MHz,
set pins 1, 2 and 3 to Off. If you want a 100MHz FSB processor to run at 66MHz, set pins 2 and 3 to On. Refer to the figure below.

2-3 On: 66MHz
1-2 On: Auto (default)
1-2-3 Off: 100MHz

JP3 is right in front of the DIMM slots, towards the CPU.

Check it and see what it is set to, maybe somebody changed it from the default.

<u>You also have DIP switches to set the processor multiplier; did you change those when you upgraded your processor?</u>

It's starting to sound like your PC might have a lot of reasons to be confused.....

Set SDRAM CAS Latency to 2, leave the rest at 3.
DRAM Idle Timer set to 16 (if you have it)
SDRAM Wait State on normal (if you have it)
Snoop Ahead enabled, as it will give you PCI streaming. You can try disabling it.

SDRAM PreCharge Control = Enabled
What's this?? Try disabling it.

System BIOS cacheable = disabled
As far as I know you only had to disable the Video BIOS and Video Memory cacheability, but I could be wrong.

Video Memory Cache Mode (UC/USWC) set it to USWC (Uncacheable, Speculative Write Combining) for bettr performance.

If you have an adjustable setting called DRAM are xx bits wide, set it to 64bits for non-ECC SDRAM or to 72bits for ECC SDRAM.

If you have an adjustable setting called Data Integrity Mode, try between the Non-ECC and EC-Only settings.

I was watching TV (The X-Files on Fox 11 in Los Angeles area) while fiddling my CMOS settings:

at 100 Mhz, my tv picture gets more static (not too much)
at 83 Mhz, my tv picture becomes clearer!

HUH? Does that make sense? Yes, I have the computer hooked up to the TV with a RCA cable. I even haven't boot to DOS/Windows that far! It was just a reboot :>. The TV and computers are on different power outlets. Both are on surge protectors.

I also ran a DOS diagnostic program to see if it is just Windows that crashes. NOPE! This is random. Sometimes it passes or fails. However, it only fails if I have my bus speed at 100 Mhz! No problems at 86 Mhz! Here's the log:

Man, this is getting too weird especially the TV problem! Haha! Okay, now I know it is not just Windows that is failing from 100 Mhz speed.

If you check the earlier posts (weeks ago) in this thread, you can see my whole CMOS settings. I pretty much listed everything. Most of the items you mentioned are not there.

SDRAM PreCharge Control? I don't know! It is not listed in the manual either! WTF? I alreadyt tried disabling it. No changes!

I have tried setting the SDRAM timings to 2, 3, mixed, etc. No luck! I will try the other ideas in your reply and other people's. Ugh!

Hollyberri: I will try that jumper idea . Damn, maybe that is what I needed. I think the jumpers are at default, but I am not sure.

I already tried RAM modules idea. I tried the old module by itself, the new one by itself, mixed both at different slots, etc. Nothing really improved. The memory tests I did that failed were only at 100 Mhz bus speed. I assume RAM is okay. These are the good brands, not generic ones.

I don't think this is possible with my motherboard revision A. Unless you meant 83 Mhz? But where is that 41 Mhz coming from? I don't see any number for PCI clock speed.

[antdude]

HollyBerri: I found a small information about FSB in my manual:

"Note: Intel Pentium II processor or Intel Celeron(TM) processor supports VID (Voltage Identification). The switching voltage regulator on the system board will automatically set the voltage regulator according to the voltage of the processor.

The system board supports 66Mhz/100Mhz FSB. FSB will automatically set the bus speed according to the FSB of the processor."

Umm, I don't think I can change the FSB manually. I don't even see JP3 area on the system board layout in the manual! [sigh]

Guys, did you use http://www.dfi.com.tw/download/MANUAL/P2XBLAB+PR.PDF to read the manual of my specific motherboard model and revision? This is what I have (printed copy). Except mine doesn't have foreign languages.

[Rags]

antdude,

Would you just set the ****ing jumpers like Motub asked ya to several posts ago. Jeeeez, you are making this MUCH more difficult than it needs to be. Yes, your FSB affects the frequency of your AGP slot. I am confident this is your problem.
