AMD - Less then impressed...

[JeffG]

Well I went the AMD route for the first time in 2 years, the last AMD system I built used to hang my NT machine and I stayed away from them after that.

This time I bought the AsusA7V and a Duron 750, 256PC133 with the Asus V7700 vid. It looked like the bridges were connected, so I left them alone and installed. Life was fine at 750, installed the OS and some of my software.

Last thing before bed was to try some soft menu adjustments. I dropped the CPUx down to 7.0, bumped the clock speed to 110 and the voltage to 1.65

Toast. No POST, nothing. I've switched between the default factory jumpers and the jumperless mode and it does absolutely nothing. HD spools up, power comes on but zero dispay or beeps. Anyone else seen this?

 

[Gunbuster]

Hmmmm setting components out of spec. and having problems, lets burn AMD at the stake

 

[noxipoo]

umm, reset the bio duh. seems like users fault regarding OC.

 

[Grendel99]

Um...last time I checked the 750 Durons did NOT come factory unlocked. And 110 FSB on the KT133 chipset is pushing it.

So you probably need to unlock it. Or Leave the multiplier at 7.5 and raise the FSB and voltage. 1.65 isn't that much. Try 1.7, 1.75, 1.8, and 1.85.

Also you might want some better cooling.

 

[JeffG]

I would love to adjust the BIOS per Grendel's suggestion, but unfortunately it's a bit difficult as it's dead as a door knob.

As far as setting the BIOS out of spec and the stunned amazement that someone would actually try this... duh. I read the articles on this site as well as Tom's - I'm sure you are aware of them. Prior overclocking of my Celeron resulted in zero problems running 24/7.

Cooling should be adequate, I purchased an larger aftermarket sink and fan.

<< It looked like the bridges were connected, so I left them alone and installed. ... I dropped the CPUx down to 7.0 >>



The L1 bridges do not come from the vendors connected. Some of them have been laser cut according to your CPUs multiplier. You have to manually connect them yourself using a pencil, windows defogger kit, or conductive pen before you can change the multiplier using the bios.

As noxipoo said, you may have to reset your bios at this point. Check your motherboard documentation on how to do this.

Also, when overclocking, start off with smaller steps and work your way up until it becomes unstable, then back off. You don't need to apply the extra voltage unless your system becomes unstable and you want to continue trying to overclock. With AMD systems using the VIA KT133 chipset, like your ASUS A7V, the FSB overclock doesn't work that great. 110mhz is pushing it. It's much better to just change the multiplier. In your case, first connect your L1 bridges on your Duron. Then, change your multiplier in bios from 7.5 to 8.0 and keep going up from there checking your temprature and stability. You should be able to reach 9.0 (900Mhz) easy if you are using a good aftermarket heatsink.

Here is something to try out, try flashing your BIOS back to defaults via the jumper near the battery. Perhaps if you put back the BIOS in the default setting, you will post again. I've done this before to my own system and only by wiping the BIOS back to the defaults was I able to get back onto my machine.

[soulm4tter]

you are going to have to clear the CMOS, which is really lame with Asus boards. Get out your manual and start reading.

 

[newbiepcuser]

Your judging AMD based on your lack of knoweldge on how to setup an overclocked machine. Screw AMD then, they should included manuals on how properly connect the bridges, and throw in Tornado Case while they are at it. Heck, how about Hedge Hog Heatsink for that toasted Duron of yours. Intel is better choice for you then.

But besides that: set the jumpers clear out the BIOS, power up if you still can and then shut it off. Remove the power cord from your machine, (read this somewhere in some A++ book) to gurantee the BIOS is cleared. Give it 3 mins. Power up again, set your bios back where it was stable. Think about getting a new heatsink, fans for the case, etc. Then you should be good if your processor isn't toasted.

Dude clear the CMOS! You don't need any power to do that! Man I hate to be mean but you can't blame AMD for your lack of OC ability. If the CPU is overclocked too much, the machine shuts down and you hve to clear CMOS first. Just hope those PRIME95 lovers don't come and bite your head off!

 

[sak]

Man look i have to same problem when i tried to do the same thing to my chip. but this was not the chip fault. i mean your are setting the chip outta bounds than what it is setup as in default...

if you do this you expect to see few problems...
I will have to reset the CMOS chip on my motherboard...not all I have to do is to figure out out to reset the darn thing my my asus a7v133..

 

[JeffG]

I read the manual several times looking for a reset on the Asus. The only thing I found was a reference to an automatic reset if the board fails to POST. Switching over the jumpered mode with the factory defaults for the 750 would have cured the problem (I thought) but it did not. I'm going to dig around on Asus's site later to see what I can find. I was hoping someone here had already discovered how to reset the board manually.

Yes - I certainly expect things to not go smoothly when running out of spec, but I don't expect the chip to pop when someone sneezes. I made what I felt was a fairly small change.

I have the conductive ink pen, but after looking at the bridges through a magnifying glass I really thought they were connected. Plus it was my understanding that if they were not connected, the bios adjustments wouldn't effect much, and I thought it would be smarter to try a small adjustment to verify that the CPU was unlocked.

 

[Duvie]

Trust me buddy it is you!!!!Many have this duron (maybe one of the best ocers around) and can get it to 1000mhz with great air-cooling alone...I agree many can't seem to get to 110 with ASus mobo...107 may be closer to what you will be able to achieve...

Start messing with fsb and you were likely oc'ing your memory too much as well...what brand...what settings?

Locate the northbridge chipset and the pll clock...get some cooling on that as well...it may help you irk a few more out of fsb...When I oc'd my fsb past my memory's ability and it didn't post I pulled the battery on mobo for a few seconds, placed it back in and I was back to defaults....

When you get it up leave at default 7.5 and run fsb one at a time..I bet soft oc you can get 107 for 803 mhz...My biostar I can run 7.5x112 for 840, memory jacked to highest settings.

Otherwise you can go back to your inhell celery at 66fsb...

 

[JeffG]

Memory is Corsair 256 PC133 CAS2

The battery pull on the MB is a great suggestion - thanks!

 

[ToBeMe]

I agree! Don't blame AMD for this problem!...................but on the other hand........no reason to crap on this poor soul either! He's just P.O'd because of his troubles........geeze, give the guy a break! Jeff, just do like they said and pull the battery........let it set for 10-15min., replace it and try booting! let us know how it goes and don't be down on AMD......it's not their fault the way it sounds........don't be to worried about the flames either.......everyone makes mistakes dude......just get it straightened out and you'll be fine! (might want to change the thread heading though.....)

 

[jaygayPayCash]

yeah thats for sure .... Long live AMD souls

 

[Duvie]

Yeah sorry if I was rough...I would change title though...say something like &quot;amd oc'ing problems&quot;...

Memory looks great...I am pretty sure that memory can do 110 fsb with settings jacked...that would make the pc133@146mhz.

Look at northbridge chipset pll chip cooling if you want to go soft oc route...

 

[Noriaki]

wow you guys calm down...he's just asking for help....
So he's a little disturbed that a seemingly 20Mhz overclock messed up his system...I think you'd be to...I'm sure we can help him just as well with out telling him he's an idiot.

Anyhow, JeffG:

The Via KT133 chipset was piss poor at overclocking FSB wise....

110Mhz FSB is risky on a KT133 chipset Stupid via...
I highest I've ever seen is about 115....120 would be astounding...

You want an A7V133 for 133Mhz FSB if you are going to try that way.

You should be able to unlock the duron and overclock by the multiplier but do not overclock the FSB on KT133 chipset.

Try pulling the battery or resetting the CMOS...

Unforatuely after messing things up in jumperless mode simply switching to jumpered mode might not work, because you have to set in the BIOS that you want jumpered mode as well...(I don't get it...there is a jumper for jumper/jumperless mode, but there is also a BIOS setting for it...stupid I know...)

And clearing CMOS on Asus boards is a whore....it has two solder points you have to short...not a jumper usually

Sorry I can't bring you better news :frown:

I hate Via as well...I feel for you man.

 

[Rectalfier]

I can't even get my KT133 mobo to 106, what makes you think your's should handle 110. What you are doing is the same as an AMD lover trying to set the multiplier on an Intel chip.

 

[TravisBickle]

if you will attempt things like overclocking you might as well do as much reading as you can. the clear cmos jumper and removing the battery are pretty basic. i would be very surprised if anything is damaged here. did you have the chip in the right orientation when you looked at the bridges?

 

[Boonesmi]

i have the same motherboard, when i was first setting it up i tried some different overclocking combo's, a couple times the same thing happened to me as what happened to you, i just had to clear the cmos (by shorting the two pins on the motherboard, the manual explains how) and then i tried a dif combo till i found something i liked.

for me i didnt end up overclocking the fsb (the darn kt133 chipset isnt very good at it) so i run my 650 duron at 900 by way of 100fsb and 9x multiplier

 

[JeffG]

Boonesmi - thanks for the input! I looked high and low for a MB reset but haven't found it yet. I've just downloaded the lastest manual from ASUS and I'll look for it in there.

The dead blank screen and lack of any noise from the case sort of leads to a bit of depression...

 

[JWMiddleton]

Hi JeffG! Guess you step into a pile sh!t here...pi$$ed off a few AMD fans! Oh, well!

Risky does not mean that it will harm your CPU. I am sure things will be just fine once you clear the CMOS. I bought an A7V133 and a t-bird 750 for my step-son. I was VERY impressed with the performance! They make a great product and one that seems to overclock very nicely.

Good luck!

 

[Sugadaddy]

Asus boards usually don't even need to have the CMOS cleared by removing the battery. Just unplug your computer, set the power supply switch to OFF, and press the Power button on your case a few times. Wait a couple of minutes, and the CPU settings should have set back to default.

Now for overclocking, you should have done a little reading before you tried it as AMD overclocking and Intel overclocking is very different. First, I'm almost sure that your Duron is multiplier locked, so you'll need to close the bridges with a mechanical pencil. After that, your best bet is to change the multiplier and leave the FSB to 100, since your motherboard won't get very high overclocking the FSB. (110, especially on Asus boards is too high) My mobo doesn't even boot at 107... So increase the multiplier 0.5 at a time, and if it gets unstable, increase the voltage.

And next time, do a little research before blaming things on AMD...

 

[madbitch2001]

It is not a clear cmos jumper, you have to short to soder points. Use a flat head screwdriver, and it is most likely by the battery.
