Ocin fun

I'm havign some problems overclocking here.

Asus A7v133
AMD 1.3ghz (100fsb) Axia? revision
256mb of cheap arse ram (one stick MIGHT be micron, i can't tell)
POS Geforce 1 SDR SE (GPU clock 110, ram 143)

Ok, linux overclocks to 1.49ghz fine at 1.85v

Windows fudges up at 1464mhz and isn't stable at stock speed in 3D games, but it is in 3dmark.

Thats right, its not stable in 3D games, or any games for that matter at stock speed. I tried lowering th e fsb to 130 and 95mhz (changin multiplier too) but it still isn't stable. I have an old socket7 heatsink on my vid card gpu, and nothing on the ram.

Are blue orbs good for video cards? it seems like my 1st one was a POS. Any other good ones?

Is it me videocard, ram, or drivers?

Would it be worth it to get 512mb of crucial CAS2 PC133 to replace my other ram?

How can i check if my one stick is micron or not, any utilities?

Put a Blue orb on my TNT2 when the fan died, all ok so far:cool:
Crucial or Mushkin use em both....good stuff (150Mhz):D
HTH:D

Ok, get this, 150fsb werks at 1200mhz almost... had a registry die

gotta fiddle with my video card settings.

What are some BIOS options I should look out for? (for AGP and vid card)

[Dave S]

for the AGP i left the BIOS as it came, just played with the memory settings:cool:

[MechCD]

I'm thinking its not the ram, how would i tell?

Gee I sound like i've never overclocked before, but these VIA boards are just friggin picky/unstable with only one setting being changed!

I remember when it was like this

1 set jumpers or jumperfree mode
2 set voltage
3 test
4 if test passes yer good
5 if test fails, lower clock a lil


now its like this

1 set jumperfree mode
2 hope jumperfree mode works right
3 set multiplier, hope that it sets the right one (ive had it set the wrong one)
4 set vcore
4a test
5 fiddle with ram settings
5a test
6 fiddle with drivers
6a test
7 underclock to make sure it works ok
7a test
8 find out it doesn't work ok at stock
8a screw testing it
9 crank voltage and fsb and hope it werks
10 find out amazingly its more stable overclocked than it is at stock

[Dave S]

Have you got any other memory you can try, or nick form a mate, as for the rest not sure mine are all Intel/VP6 - good luck tho:)

[wbierman]

I have always used Matrox cards because thay could handle over clocking.

There are no garantees with OCing. Either you have hardware that can handle the higher settings or you spend a lot of time going nowhere. Make sure you have the best memory and try different video cards until you find the right combo.

[dnar]

will, how far you think the G450 can be pushed???

I have ran a G400 MAX at 150fsb on a BX mobo which is 100Mhz AGP. It ran great.

[wbierman]

pretty high

They have always had that ability going back to the Millenium and the Millenium II.

Mech, run your ram bus at -PCI and then set your fsb to 150. This will let you know whether your ram is limiting you. I am leaning towards this being a PSU issue. What wattage is your PSU? Is it working as it should? Can you swap it for another to test it?


The Geforce will not be the problem (hardware wise). I have owned a Geforce 1 and it would run at over 100MHz AGP bus on a BX board.

Also, it may be worth running 1 stick of ram at a time and then swapping it for the other....one may be dud.

[Dustin]

I think it's a vid card problem. Try running AGP 1X, or 2X in the BIOS.

There's an easy way to check your RAM. This program will tell you anything you want to know about any RAM stick, as long as the SPD EEPROM programed correctly.

Well, i really think its the PSAU, the RAm does 150, i trieds it at a low multiplier (underclock CPU, overclock fsb)

After talkin bout it with dnar fer a while I really think its the PSU. It sometimes doesn't boot. it sits there, no hdd spinup no beeps no video, but the hdd and power lights come on. Shut it off an turn it back on it starts up OK. Also happens on a warm boot.

300 watt pc power and cooling supply. Not recommended by amd :( need at least a 350 watt of same model.

Anyone got some links ofr a cheap quality powersupply thats over 300 watts? 350 or 400 sounds good. Phil mentioned 400 watt antec, but thats a lil to expensive fer me ($99)

Some of those are also symptoms of a bad vid card too. I have a Diamond FireGL1000 that does the same thing. I have to power it up and down many times to get it to boot. It does the same thing on every mobo, sometimes less on some, sometimes never booting at all.

The no HD spin up would make me believe it is a power problem.
I don't remember the Antec 400w being so high. I picked up my enermax for ~$119 at Fry's.

[MechCD]

Smooo! more than $75 is too much for me to spend.........

Der EBAY!

unless i can rig somethin with these here 200 watt AT supplies i have laying around....... But i don't wanna gut me case again to mod it so another psu will fit.

[phil]

Mech, you may get the Antec cheaper locally....the $99 price tag is direct from Antec.

[MechCD]

I'm not sure if me local storees have this kind of stuff, but i'll look around online. I might try hooking my hdds and fans to one of those 200 watt AT PSUs just to check, but that probably won't help much.

I'm not sure if the hdds don't spin up. They seem to turn on, but i can't really tell if they spin up or not. I think they do, but maybe one of them doesn't.

If the power supply were overworked (mobo needs more current than it supplies)woulnd't it get hot? From my limited robotics and electronics projects, power supplies get very hgot when you draw too many amps from them, the exhaust from my PSU is cool, and the thermally controlled fan is spinning slow, not fast (so its not running hotter to make the fan speed up)

Could it be the video card?

[pelligrini]

Could be the card.
Do you have acess to another machine to test it?

Sure would suck to spend the bucks on a new PS and that not solve the problem. Been there, done that. :(

[MechCD]

I could put the geforce in a rrather fidgity (doesn't like AGp stuff) mobo, but i don't know if that would get us anywhere :) It took me a wekk to set up a TNT2 Vanta on it.

This geforce wokrded fine when there was a 1ghz tbird in the system, the upgrade to a 1.3 is when it started gettin screwy

[pelligrini]

If you are having problems with it not posting in your current setup, see if you get the problems in another. You don't have to install it in the OS.

That is what makes me think it is your PS. You have admitted that the PS is only rated for a 1Ghz T-Bird, yet you are running 1.3Ghz+ and have 3xHDDs etc.

[Yo_Mama]

This happens to me on my A7V every boot, here's why:

I keep the voltage set to 1.65 in the BIOS (which is undervolted from the stock 1.85). 1.65 isn't enough to get the MB running. So when I reboot, the first time it does nothing - just the HD spins up. After powering down, the hardware default voltage (1.85) takes over & carries me into the BIOS, where I set the voltage for user define & 1.65V. Sounds silly to do this every time I reboot, but the extra .20V makes a big difference on CPU temp...

[MechCD]

Thats exactly it..... But how to fix? it does that at STOCK SPEED and voltages?

[Yo_Mama]

Got me there. :( Try setting the voltages using the jumpers instead of the menu. For some reason the jumpers work better.

The problem here is the CPU is booted up at it's default Vcore of 1.65 at the overclocked speed before the BIOS kicks in and switches to a higher Vcore. If the CPU won't post at the higher overclock and default Vcore, you are stuffed. Now, to make your CPU's default Vcore of 1.85V, close all L7 bridges with a pencil. This will make the mobo think that the default Vcore is 1.85V and will provide the extra voltage required during the POST. The Bios can now be set with a lower value if required and the mobo will then switch to that Vcore after POST.

Hope this helps.

I really should go and do this, just haven't gotten around to it. ;)

[MechCD]

dudes, it does this at default volatge and clock. its not cuz the voltage needs to be 1.85



1.333ghz (almost stock, should be 1.3 :) )

1.75 v stock



sometimes won't boot.



Does that t 1.3ghz too



does not do that at 550mhz 1.45 v :) (super cool, cpu temps is a few degrees away from ambient at this speed and voltage)

There's your answer then...buy a new Power Supply or run at 550MHz :p Go on, twist your dad's arm....tell him it is to save mankind ;)

[MechCD]

He's already spent more than usuall on saving man kind and curing cancer :) He paid for my water block, my bong cooler that i didn't use, the vid card for the 600mhz system that isn't up yet, half of the router costs...... he's a nice dad.

Before this, I paid for most of my stuff, he just got me a monitor or maybe something small like a new mouse.... Now I dunno what happened, a change of heart? He's gettin me all this stuff and I'm a bit puzzled, I feel like I wnat to pay him back somehow.....

Anyways. i think I'll pay for the new PSU :)
I try to pay him back with stuff like, quieting his puter down and making the colors on his monitor look right (he like to mess with the gamma and stuff and then the screen gets all cludgy :))

My dad also forked out $20 on my Pegboard Cube, he paid for the 1 can of spraypaint, the hardware (nuts and bolts etc) and the small bucket of arcrylic enamel
