Am I hitting the dreaded "voltage wall"?

post #1 of 29
Thread Starter 
Hi all just trying to figure out what the problem is here. I can 4.0 ghz stable with 1.375v. My nb is at 3000mhz with 1.35v. Ram at 1332 MHz with 1.52v. Ht link at 2750 with normal voltage. Ocing with 250x16. My only problem is, if I try and go for 4.1ghz by upping the multi, I can't get it stable with 1.425vcore. I didn't try it with 1.45, and I really don't want to push it for that. Just wondering is this rhe dreaded "voltage wall" that people say exists in amd CPUs?

It looks like your problem is your HT link, you want to keep that as close to 2000 as possible, so lower its multiplier a bit and try again

Theres not really a voltage wall on AMD chips, but they all have a point somewhere where it takes way more voltage to get any higher. What cooling are you using btw?

oh. psh, you have plenty of headroom then
If your chip is anything like mine then 4.1 wont be very stable no matter what voltage you use...

just to be sure, you have spread spectrum disabled right?

Umm not sure what spread spectrum it tbh. Sorry for my dumbness lol. Where is it exactly?

ht link =keep as close to 2000 as possible..i think with your settings..pick the one around 2100-ish..cpu/nb frequency should be around ..2750? or the next step up if your chip can do it..what are your load temps? NB voltage should be around1.28-ish and cpu/nb voltage around 1.3-1.4 (i'm looking @ settings for 250 X 16.5) ohh..and 1 more thing MOAR VCORE! ..up to 1.56 if temps allow..which with your setup..i would hope so..i was getting 48 prime and 53 ibt with a RASA

Ht link is at exactly 2000. CPU-nb is at 3000mhz and 1.35v. Nb voltage is at 1.1 which is stock. Load temps at 250x16.5 and 1.4 vcore haven't passed 32.5 (currently testing). I have noticed that if I would try for 4.1 ghz with just multi ocing and on 200 fsb that my temps would be about 7-8c higher most of the time. Would that just mean that 250fsb is my chips "sweet spot"?

And should I not pass 1.55vcore under load or don't set it past that in the bios?
