My RAM's stable at 1600MHZ CL8.
On an AM3 set up the TEC won't kick in..
Really need a new cooler XD.
It's a shame you can't adjust the TEC to kick in sooner

I'm still shocked that with the size of that thing it still can't handle it just as a fansink

I've ruled out me not mounting it correctly..
As I've tried several times..
On an i7 set up or whatever, it'll be fine..
On an AM3, it's not great..
On an X4 it might be better I suppose.

Might be worth giving this a go:

Not the butcher job at the end, but changing the thermistor to one that'll feed the TEC power at a lower temp.
PCZ - No idea why you are getting throttling then, as you are no where near the throttle temp for the CPU, and you have beefy power reg and cooling on that board.

My CPU doesn't throttle :S
Soldato
Was talking to PCZ
He's getting throttling, but he's got a top end mobo and his CPU temps aren't anywhere near the throttling temps.
Caporegime
Was talking to PCZ
No, I mean..
I've got a Crosshair IV Formula, and my CPU's been at 70C (Due to TEC not kicking in) and I don't throttle.
obviously every chips IMc will be different.
PCZ - Try to lower your CPU-NB to 2400 and then use 1600Mhz - thats what works for me. I can easily pass prime stable for just over 12 hours with CPU-NB @ 2600 but it causes problems after 12hours so I've reduced mine down to 2400Mhz (4x2Gb sticks of DDR1600 @ 9-9-9-24/2T)

if some peeps are running NB@2600 and some NB@2400 ... is there gonna be a noticeable drop in performance ? ... would it be better to run a lower NB as long as its fast enough to supply the cores/ram than have too much headroom
is NB@2400 enough to supply the grunt to the cores @4Ghz ? .. just wondering as a lower NB is gonna need lower volts and result in lower heat
me showing my noobness again .. lol but these questions need asking
by the way i got cpu-vcore prime stable @1.425 bios reading (1.445 cpu_z reading) for the first time with lower ram frequency but tighter timings

I finally have a day to play about with this 1090T
Going to be running tests to see how NB speed affects performance at 3.2, 3.6 and 4 GHz.
Im using a Crosshair IV Formula, 1090T and 1600 MHz ram, and it works fine. No throttling.

Would be good to find out what triggers the slowdowns.
Obviously it is temp related but what component throttles back.
When i noticed it i had the NB at 2800 and a fairly high vcore.
To run the NB at 2800 i had to increase the MB volts and the CPU-NB volts.
I have already tried the RAM at 1600 with the NB at 2GHZ to see if i still run with low vcore but couldn't
Need to see if that is also true when i try with different RAM this evening.

Just read the first page of this thread, can it really get 4GHz on stock voltage?
Associate
Technically yes, as the cpu voltage for turbo core is 1.475v.
Most if not all of us can do 6 cores @ 4 gHz for less than that
Have you tried overvolting ram slightly? Mine is rated at 1.35v, but on auto is 1.4v. This ram is on the Asus QVL, and ive found forcing it back down to 1.35v makes things unstable

That with the AM3 bracket, would that be my best bet?

Things are a lot better now i have swapped the RAM out.
The GEIL RAM is running nicely at 1600
What is worth noting is that initially i had the RAM voltage set to 1.65V and i was getting errors running IBT.
Thinking the RAM needed more juice i upped the volts to 1.75, this made things worse..
Dropping the MEM voltage down to 1.5v sorted everything out.
Just doing 50 runs of IBT on high to be sure.
Then a long P95 blend test if it passes IBT.
Edit:
I have discovered why i was experiencing throttling.
Loaded up the ASUS AI suite and looked at the CPU temp.
There is a very large discrepancy between the AI readings and those of Coretemp.
Looks like the thermal protection is trusting the same sensor readings as AI suite is displaying.
Might explain why mid 50 readings in Coretemp are on the throttling point.
Screen below shows my PC running small fft's at 4.2GHZ with 1.488 vcore.
This is a bit below throttling point but serves to illustrate the discrepancy in temp readings.
Coretemp is reading 49C (0.95 and 0.96 read the same)
AI Suite is reading 68C

Im having a problem with my 1055T , sometimes it doesnt goto full power mode from its power saving state, its very random.
Heard a few others having the same problem with different motherboards on extreme forums.
Thing is , is it the chip or the bioses? hmmmm
