What's a good clock for a 1100T?

Seems to do 4.0 GHz easy, on 1.4v atm trying for lower right now. 4.2 with 1.55v seems stable and 4.4 isn't stable at all even with 1.6v.

I was hopeing for 4.4 GHz, do I expect to much? All I'm changing is the multi and vcore.
 
aint that a little high on voltage?, i would thought 1.4-1.45. would be the highest you would go with out frying your chip, or is that just me.

4ghz would be good enough to stay at IMO.
 
A lot high on volts I would have thought. Try to stay under 1.45V

With a 20 multiplier (4GHz) you could try upping the bclk from 200 in 5MHz steps. make sure you set the pcie at 100 though first. This will give steps of 0.1GHz. It will also OC the HT and NB and memory though.

Example, bclk 205MHz HT 2050MHz NB 2050MHz Mem 1640MHz (if it was 1600) you may need to reduce memory multiplier a notch.
 
Those volts are fine for Phenom II's as long as you can keep the temps under 62C.
 
I'll probably go for 4.1 then, wasn't sure if I was missing some setting that was holding it back.

1.55v is the safe max apparently? when turbo core is enabled the default vid is 1.475v.

What's a safe 24/7 CPU NB voltage?
 
There was a discussion around safe 24/7 voltages on xtremesystems a few months back & if I remember correctly 1.48 max was advised & some degredation has been seen from voltages above that. The 6 core cpus cant quite tolerate as much voltage as the old 4 cores.

1.3-1.35v should be safe for the cpu-nb.

What software are you using to measure temp as everest & hwmonitor measure the correct temps for me.
 
I'll definitely stick around 4 then, should be well bellow 1.48v then, cheers..

That's a nice OC you got there, I'm needing 1.35v for 3GHz NB and 1.42v for 4.0 GHz CPU :(

Hoped 1.35+ was ok for CPUNB so I could push for 3.2GHz, going from 2.4 to 2.8 added an extra 32FPS onto the second pass of an Xvid encode alone.

That's on air though with:

NH-D14
Corsair XMS3
Gigabyte GA-890GPA-UD3H
 
Thats a good overclock on air.

I overclocked mine by increasing the HT as I found it required less volts to overclock than just upping the multi, but generates a bit more heat.

I have multi @ 14 & HT @ 300 for 4.2 GHz with cpu-nb & HT Link @ 3000. When I was just overclocking with the multi I needed around 1.46v for 4GHz with cpu-nb & HT link @ default (2000).

Upping the cpu-nb speed makes a big difference in encoding & 3d (eg games) which most people dont know & most amd cpu reviewers ignore (or also dont know) so dont show the full potential of amd cpus. The only proper review article I have seen regarding this was one of Anandtechs amd motherboard reviews.

I tried using the bus instead but didn't lower the multi that far and have been leaving HT at 2000, just gave it a go though:

It does seem more stable at lower vcore

Core: 4.2 GHz
Multi: 14
Bus: 300
HT: 3000
NB: 3000
VCORE: 1.50 v
CPUNB: 1.375 v

Got a maching_check_exception BSOD during IBT with that, going to try a higher vcore now. Just wanted to ask if your changing any other voltages, like NB and RAM or anything else?

I was supprised by how many reviews ignor CPUNB clocking aswell, I learnt about it's benifits from reading forums.

I would try leaving HT and NB at about 2400 to 2700 by lowering their multiplier from 10 to 8 or 9, it would be more stable I think. Nice clock though.
 
you should be aiming for no less than 4.2Ghz mate

1050T go to 3.8
1090T go to 4.0
1100T go to 4.2

average good clocks - Thats what you should be aiming for with a CPU-NB of 2600Mhz minimum.
 
Can you add volts to that?

I think my MB might be holding me back or my CPU just has a 4.0-4.1 wall without lotsa volts, would help if I had finer increments aswell.
