Oc stops at 1470??

[Doror]

Hi you guys, I´ve tried more but then windows screws up. It said windows preotection error when I tried 150 * 10. Now I´m running it at 10,5 * 140. Seems to be stable. What is holding me back??? I´ve got 512 crucial 133 set to 2,2,2. And a geforce 2 pro card....
I would really like it to go above 1500...

1) what kind of chip do you have?
2) what stepping is it?
3) what kind of mobo do you have?
4) can you bump up the voltage?
5) what kind fo hsf do you have?
6) what kind of power source do you have?

1. Tbird, 1333 ayhja stepping
3. Asus a7vk133a
4. Yes I can.
5. I have a global win wbk38 6800 rpm fan with al. heatsink. Heat is not an issue, runs now at 47°
6. 300 watt enlight.

Try going for a 14 multiplier with default fsb, then slowly increase the FSB in 1mhz increments until you cannot post anymore. than you will know how fast you can get that puppy going.

 

[Doror]

Already did that, would not go over 140.

I would set the multiplier lower and increase the fsb. But you have to lower your ram timings. You probably have them set too aggressively. Try user defined and 3-2-2. If that doesn't work, try 3-3-3. I have the same mobo and an AYHJA. The FSB seems to be the biggest OC killer, as the board seems like it isn't stable beyond ~150mhz. Also, your RAM might be a limiting factor, if it isn't good it'll crash ya. I put Ttake heat spreaders on my 256 micron pc133, used the 3-2-2 ram timings and I have mine running close to 1.6 gigs at 10.5x152. I'm having problems going higher on AYHJA-Y b/c of my PSU and the pci bus (need a 1/5 divider!!!!) any higher than its set now. I could probably get over 1.6 with a better PSU, but I don't feel like shelling out $80-100 bucks on a good 400+W PSU. Good luck. Oh yeah, I also bumped up my Vcore to 1.80V...make sure you have good cooling as this will raise your temps by at least 3-6+C depending on your current cooling solution. Check my sig for the rest of my specs.

Damn double post....anyway, I have an enlight 300W too, also, don't jump your FSB so high so fast. Go by 2's or so, then when u get unstable, back it down one. Mine is stable at 10.5x152 now...ran 3dmark in a loop last night and woke up and it was still fine....now...the 1005a bug where it fails to restart sometimes is annoying....anyone try 1006beta yet?

Hi, and thans for the help. The best I can get is 9,5 * 156 = 1482....
This is with my memory at 222
Even if I change it to 333 it wont run windows at 9,5 * 157???
Weird

 

[Doror]

Bad news it wont run 3dmark at this setting

 

[Doror]

Could my 3dcard be the problem??
It wont run 3dmark at anything above 1470 mhz.

 

[chizow]

I doubt its your vid card unless you have it OC'd as well. If you have your card OC'd, I'd un-OC til you get your CPU stable. If you can get it to boot at @ 150 fsb, I'd stop there. I'd try upping your multiplier to 10x150, then 10.5x150. If you don't want to go much further with the multiplier, then creep back up on the FSB, but again, 153mhz seems like point-break on the A7V133. Also, you will probably have to up your vcore voltage, as well. Try using your previous settings, but increase your V-Core and see if it'll run. If you can't run 3dmark, its probably not a speed you'll want to stay at for very long. Also, knowing your stepping is very, very important. It gives you a threshold u are confident that you will hit. I have a 1.4 AYHJA Y, so I knew I should hit 1.6 easy. I'm also gonna try putting betterThat being said, I'm not sure how much further I can go 'til I get a 1/5 pci divider in the bios or I get more power/cooling.

what voltage are you running the cpu core at to go over 1470 with my axia i have to bump the voltage up to 1.88

 

[heffe734]

You need to bump your voltage more...and you need to change that 300 W PSU.
