Maxed out at 2.3ghz, and vcore stability ques.

[Sprocket]

Well, it seems 2.3ghz is the highest OC I can get stabley. I've booted into windows at 2400mhz and higher, but none were stable even at 1.85 volts, and the temps rose to 52C once, also... soooo, I guess I'm pretty much stuck here at 2.3ghz, which really isn't all that bad I guess. ;) but, I'd like to go higher. :D I've got a 2500+ Barton I haven't tried out yet. Hopefully will get to do that soon. Even if I can only make it to 2.3 with it, at least it'll have better performance at that clock. :cool:

couple of days ago before I started pushing it past 2.4ghz with higher volts, I was running 2.3ghz (200 X 11.5) set at 1.7 volts in the bios and it was stable. But today when I dropped it back to 200 X 11.5 with the 1.7 volts I had used before--it was unstable (if I remember correctly, it was freezing in 3dMark). So, I upped to vcore to 1.75, and ran prime95 for a couple hours and it seems to be stable now.... Why isn't it stable at 1.7 any more? Did it get somewhat dependent on a higher voltage or something, since I was giving it more at the higher clock?

I dunno. but, I was able to make it through 3dmark with my cpu at 200 X 12 and 1.85vcore. But it inly ran prime95 for about 14 minutes.

Another thing I'm going to have to do is lower my multi and start experimenting with different fsb's. But right now, my main ques is about the voltage--having to increase from 1.7 to 1.75.

thanks!

2.3ghz is the average oc for a 1700 and air cooling.
you need better cooling to get it any further.

yeah... well, I am pretty content at 2.3, but I would like to up my fsb. and that's what I need help with now. I just lowered the multi from 11.5 ro 10.5 and upped the fsb to 219, still 2.3ghz, but 3dmark just practically didn't even start. I've got twinmos winbond pc3200 256mb X 2 BH-5

how much vdimm get the BH5? mine get 2.8 Bios (2.9 real) and make 225 2-2-2-5

yeah, I haven't tried to up the voltage to the ram. guess that's what I'll have to do later. I'm not too woried bout it right now though. where's a guide to memory timings?

[sandman]

I've hit kinda my limit as far as reasonable overclocks go. Mine did slightly better than yours, but your barton will probably do better.

My 1700+ maxes at 2424mhz, and 1.725vcore.

Sprocket, what memory timings are are you at right now? At 219, it could be either your memory or your NB that is causing the problem. Don't you have an NF7-S? If so, try raising your vdimm to 2.9v, set your memory timings very relaxed (like CAS 2.5 8-4-4), lower your multiplier to 8, and try 219 again.

If it doesn't work then, try raising your vdd in the bios to 1.8v. Try again. If that doesn't work, then I'd say it's your NB. If it does work, keep going up on the FSB until you hit another wall.

[Sprocket]

thanks Brainstorm. I'll try that. ;) yep, I've got the NF7-S v2

[BrainStorm]

Hmmmmm....you may not be able to set the vdimm any higher than 2.7v it appears. Anyway, set your vdimm as high as you can and do what I said above.
