Stuck at 1266

[srwven]

I am a newbie and recently unlocked my Athlon tbird 1133. It wont even let me post at 10 (default is 8.5). Without unlocking it, my highest FSB that was stable was 144 for a speed of 1224. Now at 9.5 the highest fsb I can achieve stable, is 133 for a speed of 1263. My system is as follows: Shuttle ak31 v3.1 mobo, 256mb micron ram, powercolor geforce 2 mx400 video in the agp, a motorola modem in the pci, with swiftech mcxc370 hs/fan. I raised the cpu voltage to 1.8 with no differences. Before unlocking the cpu, I had tried to raise it above 1.8 and it wouldn't post. I have a cheap 300w powersupply. Could this be a power issue? Should I go to a 400w antec power supply?

hey there - welcome to the forums!

how did you unlock your athlon? if you used pencil, I recommend using some other form of conductive paint. My experience, when I tried to unlock with pencil I was only about 80% successful - using defogger paint (picked up at a local Auto-parts store) I was able to change the multiplier to anything I so chose.

it could be your power supply - install some monitoring software and configure it to display your 5v line (perhaps use MBM, mottherboard monitor). Then when you boot into your OS with 12xx speed, check your 5v and see if it is too low out of spec.

Sorry I assumed you were using a Windows OS - let us know which OS you are using. Also your temps - maybe you are runninng too hot?

I am running winxp. My temps are at 40 and 43 under load(unreal tournament). I unlocked using the window defogger method. I do have mbm, and my mobo shows the 5v as well, can't remember what it was the last time I checked it. I have had problems where my cdrom won't work after clearing the cmos, almost like it's not getting power. I shut it down, play with the connection in the back and reboot, it works. I have moded the case with 2 intake and two exhaust fans to help with temps.

i just noticed that you have been in the forums since dec 2001 - so perhaps you have already been welcomed before I did. :-} sorry about that.

um, yea check that 5v line. To tell if your PSU is bad you would need a voltage meter and check out the connectors. Strange about your CDrom - when you say play with the connection, is it the power connection or the ide cable (assuming it is not scsi). So you are saying that it does not get power after your clear the CMOS? that is strange. Does your BIOS detect it but XP does not?

try running UT in a window and watch MBM as you go (maybe play as a spectator), this way your computer will have good load and you can watch your voltages (and temps).

unless you are already doing this - then just tell us the voltage variance.

I hate to say it but they 1133 Athlons were never good overclockers, For some reason or other they just are not.
Any other Athlon does better then them...Except the 950 and below...they had aluminum interconnects which didnt take to overclocking to well. the 1ghz tbirds do very well. My 1266 is doing very good as well. But the 1133 never did...and nobody seems to know why.

Ok, I ran the cpu multimedia benchmark while watching the 5v in mbm. The 5v dipped to 4.76 under load. Idle was 4.84 This is within +/- 5% but, under load it is close, need more power?

More power would be great, but not necessary. My 5v dips to 4.78, and I'm still able to o/c. I think it was brought up before about the 1.1 not being a great overclocker.
