Ok heres the Setup.


System #1
-=-=-=-=-=-=-=-=-=
Duron 700 (Blue)
Asus k7vA
128meg PC133 seimans

Maxtor 46gig ATA100 7200RPM

~~~~~~~~~~~~~~~~~~~~~

System #2
-=-=-=-=-=-=-=-=-=

Diamond S3 PCI Video
Maxtor 35gig ATA100 7200RPM

~~~~~~~~~~~~~~~~~~~~~


Ok been having some overclocking problems.
I have not played around with System #2 that much, mainly messing with system #1, Once I have it like I want it I will do system #2.

I have tried almost ALL combonations in cmos to over clock this duron (Yes both cpus are unlocked)

The BEST combo I have found is 8.0x 103fsb w/ 136mem CAS 2-2-2-2

Respectiable results from that setting.

But when just messing around with the sytem #2, I hit 8.5x 105fsb w/ 140mem CAS 2-2-2-2

I BELIEVE its the video...

Why?

The ASUS (System #1) if I push it TOOOO hard, it will reboot (Exit Cmos) and then will not turn the monitor back on (loss of video signal).

BUT!!! If I power down, then back up and tab insert it will revert back to 700mhz and alow me back in.

BUT!!!

If I take the no video screen.. tap Delete, hit F5 (Restore Cmos defaults) F10 (Save and Exit) Y enter. It reboots and I get back in.

Is there anyway to test this besides getting a new vid card? I am currently saving up for a GOOD GeForce MX, and would rather save my cash for that card.

Any thoughts?

Well...as far as the video card, why don't you take a peek over here to enter our SLContest for a brand new GeForce2MX?

Second off...It sounds like you're probably using 7.5ns RAM. You can tell by looking at the RAM module itself - At the right side of one of the chips, you should see it ending in either 75 or 7. It may be by itself, or at the end of a long part number. This tells you the speed of the RAM, and what it's actually capable of. To find the maximum normal speed the RAM is capable of, divide it into 1000 (EG - 1000/speed). Also, you're using it in CAS2 mode right now (2-2-2 latency). 2-2-2 is much more sensitive to timing issues. If you back it down to 3-2-2 or otherwise, you should find your results getting better.

Third and lastly, are you running the HD from the motherboard? IDE controllers have a tendency to be rather sensitive to off-timed PCI buses. Running at 103MHz for instance, your PCI is clocked at 34.3. This means that your peripherals should run faster, but some devices (SCSI and IDE controllers particularly) don't like to do this. If you're really after that extra bit of overclock, you may want to drop $35 and get an ATA-100 PCI controller. They tend to be more resilient than the onboard chipsets (Particularly the Highpoint chipsets, which is what the Abit KT7 uses).

Hope that helps!

Thanks...

Im at work right now, but will try that when I get home tonight.

Have you increased the I/O voltage yet. It might be worth a try. My two systems seem to like the I/O voltage at 3.5v. I know the Abit has the option in the Bios, but I dont know about the Asus. I think you have a jumper on the Asus mobo to increase the I/O voltage. What Bios version are you using on the Abit mobo?

Is this an Abit motherboard or a different brand? The Abit board should actually be the KT7, not the K7T, and Abit never made a "Pro" board, but they did make a KT7-RAID. And as for the 2, perhaps the KT7A or KT7A-RAID?

Sorry they are

Asus - A7V133A
Abit - KT7A Abit Socket A 266FSB UDMA100 VIA KT133A

Yes I have increased the voltage to 3.5 and 1.85

Last night I got the Abit up to 980 but UNSTABLE, so its back down to 700@901 w/133mem and stable under win98.

I did not get a chance to test a pci vid on the asus (was messing around with Win2000 Server) but I am ordering the GeForce2 GTS this week.

Until then I am going to do a case mod on the Asus and modify the heatsink/fan combo.

I will post results.

Have You Tryed Updateing your vid. card drivers.

It is DEFINATLY not a driver problem, as for when the system cycles after a CMOS change, the monitor losses the vid signal and goes into sleep mode.

I tried a Riva 128 that a friend let me borrow last night and there was no differance.

Oh well.... I guess when I get the GeForce2 GTS next week I will try again.

Peace

What multiplier and FSB are you using for those ratings? You say 133MHz, but does that mean that your RAM is only certified for 133MHz or that you're actually running it at that? I doubt that, since 901 into 133 is something like 6.7...and I don't think that the motherboard has a 6.77 multiplier... :-)
It's quite probably your IDE devices suffering here. You're probably tossing the PCI bus up further than it can go. Make sure your PCI bus isn't tied into the memory timing in the BIOS so that it's locked to 33MHz. Good thing the Abit can do this.

If you do this, then you shouldn't have to worry about which video card you have, as they'll be more or less unaffected by the changes to the FSB/multiplier. By the way, I'm sure you know, but multiplier overclocks are generally safer, since they keep memory timing in sync. If you are having trouble hitting a multiplier, though, see if you can find a PCI bus between 30 and 33, and then factor it up to whatever FSB you're using (For instance, if you pick 31, and you were running at 133, you'd now be running at 125). Once you do this, your PCI bus will be underclocked (Which is safe, but not the greatest thing in the world), but you'll be able to crank up the speed and hit higher without the peripheral dependency.

In other words, if cranking up the FSB doesn't work, throttle it back and jump a multiplier. Then try again.

Also, as I said, you can get more stable overclocks if you don't use 2-2-2 latency. The lower latency means that the memory is more sensitive to timing errors in the system. If your system is cranked up and busy doing stuff, you may need that extra margin for error.

Here is some of the settings that I have gotton to be stable.

850mhz - 8.5x 100fsb 133mem 1.85cvlt
864mhz - 8.0x 112fsb 112mem 1.85cvlt
876mhz - 8.5x 103fsb 136mem 1.85cvlt
892mhz - 8.5x 105fsb 140mem Auto voltage
896mhz - 8.0x 112fsb 112mem 1.85cvlt

None of these will allow me to reboot. what happens is windows shuts down, the monitor hits sleep mode, I hear the system restart but the monitor never comes back on.

If I hit Del then F5 (restore factory defaults) F10 (save and exit) the machine reboots and the monitor comes back on.

If I can figure out what is doing this I could possibly get up around 1gig (I hope)

Thanks for your input.

What happens if, instead of going in the BIOS, you unplug the monitor's signal cable and plug it back in?

Make sure everything in the BIOS related to monitor standby (DPMS) is all disabled.

You said that system #1 uses an AGP card, but system #2 uses a PCI card. What about that Riva 128? Is it PCI or AGP? Have you used all three of these cards in the system at some point?

I have not tried the unplug/replug monitor yet
Everything in cmos about the monitor is off

the Riva was an agp

No I have not tried the pci vid on the asus yet, that is in my wifes machine and she uses it all the time. Tring to get time to snag the card is all most impossible.

Thanks

The "Init Display First" option in CMOS...but since you said you got the same results between an AGP and a PCI card...that's prolly not it...

Let me know how the unplug/plug thing goes.
