AMD® Phenom™ II Overclocking Thread

What temps you getting at 3.8 eddyc? Also what temp sensors is everyone looking at in HWmonitor? My TMP1 gets up to about 50c under stress at 3.5 (TMP0 and TMP2 mid/high 30s), all cores are listed below 45c

And where is Big.Wayne at? He hasn't been on since before Christmas
 
My load temps are hitting 53 or so. Vcore: 1.375. I am looking at TMP1 in HWMonitor / Speedfan. The core temps
seem to be consistantly 10*C or so lower than the TMP1 values. Something about being software generated?

Yes, where is wayne? :(
 
ok heres me first results thus far, need to find out the safe thermal limit but reckon 4Ghz should be possible at a squeeze

It's just far far easier. You don't need to mess about changing the HT multi, or giving the CPU-NB more voltage/changing its multi.

You can just OC the core and nothing else.

Makes it much easier to stress test certain parts of the CPU and find the limits of each part of the CPU separately.
 
thanks for the info Hex will have a bash doing it that way during the week

Meanwhile got 4Ghz IBT Stable for now, ghetto modded a apache pwm fan to the back of my titan fenrir with a few ziptie chains and 4Ghz with enough headroom on the temps for slightly more maybe? am chucking the chip under water at the end of the month so, but just interested in how far i can push this one under air hehe

So I have spent the evening playing around with my chip. Not much success.

I tried setting my fan to pull rather than push - Temps same.
Reseating cooler with AS5 - temps same
Reseating cooler with Thermolab stock TIM - temps same

Oh well, looks like that really is the temp I am getting.

Also had a go OCing the nb. No luck.

I cant even get up to 2100. Not even at 1.35v

Does this just mean my chip is crappy? Or maybe my motherboard cannot handle it?
 
Aye 5 runs is good for a quick test, but you'll often find that it'll fail after 10+.

My usual tests is 20 loops @ 2048MB, if it passes that then you're golden :D


In other news anyone know when the AM3+ boards are due to come out? I've been wanting to upgrade my mobo for ages now :(
 
yeah i know guys lol, just 5 runs of IBT seems to show an unstable clock up faster for me than anything else so, gonna dig out prime laters and let that run for a couple a hours

Hex, not sure, rumour has it that AM3+ chips might be compatible with AM3 boards just with a simple Bios update? i think could be wrong
 
They won't be.
The 890FX chipset works with AM3+ chips, but that's seemingly only on an AM3+ Socket (Basically, I think AMD COULD make it so it'd work via a BIOS update, but chose not to.. An Intel type move... Annoying to say the least)

IBT/LinX are horrendous methods of looking at stability.
This is back when I had a 120.2 WC loop on my 1055T, note the load temperature is only 59C.

Nice OC Martin, wish I had a ChIV and water loop, seems to really help OCability. What volts are you needing for 3.2NB in your sig? ATM on my 1100T I'm at:

Core: 4.0GHz - 200x20 1.425v
CPU-NB: 3.0GHz - 1.40v

PhenomMsrTweaker is far better than CnQ imo.

My OC just passed 30 loops of IBT and then 1 worker failed blend after 110mins, vcore bump and still going after 4 hours.
IBT is good to quickly check for very unstable OC's but anything past that prime is needed. 3 hours is apparently the minimum because it takes that long for it to get into the really stressy part of the tests.

John - phenommsrtweaker looks really interesting. Might have to have a play with that.

Out of interest what temps are you getting at that OC? And what cooling are you using?
 
eddyc, 50C load with 20C-22C ambient using a D14, not sorted my case cooling out yet though, waiting for fan controller stock. Water would really help at higher vcore, these really like the cold.
 
Those are great temps. The D14s seem to be great. I really need to get my cooling sorted.

Although I am beginning to think that there is something odd about my chip. The temps seem way higher than other people with similar cooling...

Just because it can pass IBT/LinX doesn't mean it'll pass 24 hours of Prime.
If it does, it's not because it was able to pass IBT/LinX, but because it's truly stable.

Works the other way too.

I've had chips that'd pass Prime all day long, but would fail LinX after a couple of loops.

TBH you can't just rely on one or the other.

I tend to use LinX first, as it's a much faster test than Prime, and gives you ballpark stability.

I know that if I can get 20 loops stable in LinX (~40mins), then I have a damn good shot at passing an 8hr prime.

Comes down to external factors, where your case is, how warm you like your house, is your PC on your desk or on the floor, etc etc.

When I have my PC at home, under my desk, sat in a corner, about 2ft from a radiator, my temps are usually a fair bit higher than other peoples on here, when I'm at a LAN my temps drop massively as my rig is stood in a big open room with tons of airflow.

True, thanks for the advice HeX - the PC probably does not get great air flow (although temps do not seem to change when I pull it out into the middle of the room). But my room is bloody cold in the evenings when I have taken these numbers. Not sure exactly but probably around 16/17 *C. There is no radiator.

What do you think HeX? Am I worrying over nothing?

I swapped to the 1090t from my x2 555 unlocked to quad. On that I had:

3.7 GHz
nb: 2600
vcore: 1.45
nb-v: 1.325

Load temps: 51

Now I have:

3.8 GHz
nb: 2000
vcore: 1.375
nb-v: 1.2

Load temps (in same room etc): 54/55 (any higher and the multi reduces to 8 so not really sure what the full load temp would be)

Is this as you would expect? I know I have 2 extra cores to cool but I thought that the x6s were more efficient anyway? And I now have way lower voltages...

I would have expected to get lower temps than on my old 555.

Also it seems weird that I cant OC the NB at all. I cant get it to boot even just at 2100.
