lol not brown town

Oi careful, NM is the capital of violent crime in Derbyshire (apparantly), you never know who you might be insulting....

I will give that a read, although I doubt it'll help much, I have a 965BE C2, it's very rare for one to go over 3.8ghz.

1.6v is a bit high for my liking really...

El Gappo · 2 Sep 2010 at 19:03

Yeah it's wayyy to high, wasn't exactly running it 24/7 tho, it only took 15 seconds lol, gotta get it done. That thing goes at 4.2 with 1.475 volts day to day.

Mine would, but your's is a C3 so I dunno. Mine wasn't stable at 4.0ghz with 1.6v being forced through it. (Chronic vdroop to contend with though).

30 minutes gone still going temps at 51'c

Muel · 2 Sep 2010 at 20:41

If I'd done a bit more research, waited a couple of weeks for the C3s to come out, I could be joining in now.

Turned on ACC to see if it works... Already an hour of prime 3.825ghz seems stable on stock volts. Strangely enough, on the Crosshair III LCD screen, it reports the CPU temperature as 53c.
Will run it over night, fingers cross

Muel · 3 Sep 2010 at 13:30

How come you're overclocking the FSB instead of the multi?

Good result though, an hour of Prime at 1.400v is pretty good going.

Doubt my C2 would do that at stock, it needed 1.525v to be stable at 3.800ghz...

Orcvader · 3 Sep 2010 at 14:52

Tried 19x multiplier before but Prime didn't seem to like it...

Seems FSB ocing is more stable here...

Martini1991 · 3 Sep 2010 at 15:21

Erm, you've exceeded your maximum temperatures... (62c max).
Also, you're looking at the wrong temperature reading.

Orcvader · 3 Sep 2010 at 15:39

Opened up HWMonitor, cores are 62c, TMPIN0 is 53c (This changes with the CPU workload and is the only TMPIN there). Now I'm confused about my CPU temps

Martini1991 · 3 Sep 2010 at 15:40

The core temps don't exist.
Lets have a look at your HWmonitor

Orcvader · 3 Sep 2010 at 15:59

Had to quickly stop Prime for a sec, hence the 43c on the min.

Martini1991 · 3 Sep 2010 at 16:25

TMPIN0 be your CPU temp then.

Orcvader · 3 Sep 2010 at 16:48

Oh thank god... you scared me making me think the 62c was my CPU temp

I'm going to leave it there. Prime fails after 30 mins with FSB at 230mhz. Temps hit 55c overnight so don't want to fiddle with the voltages.

Hopefully picking up a AMD® Phenom™ II X3 BE tomorrow so will be posting some results in this thread!

Here's my shot at getting the best SuperPi 1M score I could, not stable at all. I then tried upping the FSB to 202 to give me a clock of 4.040, but it wasn't having it.

Next plan is to run it with a vcore of 1.575v and use the AMD Overclock utility to up the multiplier further, hopefully I can make it stick at 4.1 or 4.2ghz long enough for a run.

This is on air cooling by the way, not that it matters as it's only under load for less than 18 secs.

My stable overclock is all the same settings as that, but with a multiplier of x19 to give 3.8ghz.

EDIT: I tried booting with it at 1.6v and then using AMD Overdrive Utility to bump the multiplier to 20.5 to give 4.1ghz, but it was reading it as 1.5v so I upped it to the max that program offers, 1.55v, applied it and it died almost instantly. Giving up on that now, don't think I'm ever going to break 17 secs. Not bad for a C2 anyway! I'd like to see what someone with a C3 and a posher motherboard can do. (Mine's only a Asus M4A79XTD Evo).

Mines stable at 4GHZ with 1.45v (Phenom 2 555 C3 unlocked) temps around 51c underload, haven't tried higher than 4ghz.

BogEyes · 30 Oct 2010 at 03:43

Hey guys, just done a fresh windows install on my system;

Phenom II X2 550 unlocked to a X4 B50
Gigabyte GA-MA770T-UD3P
Saphire HD5770
4GB OCZ Obsidian DDR3 1600MHz

and need a program to monitor the cpu temp. I know that with the unlocked 550 phenom II's you can't check each cores temp, but you can check the overall temp? I was doing it when I first built up the system at the start of this year, but can't remember what program I was using! I thought it was Everest but that doesn't seem to be free anymore??

Cheers for any help, borgia.

SeraphX · 30 Oct 2010 at 03:53

HW monitor from cpuid is pretty good

Screenie?

And you don't happen to know the batch number of your chip?

BogEyes · 30 Oct 2010 at 05:27

Cheers mate.

I can remember now why I never tried overclocking the chip. The temp seems VERY high just running as a quad. Think I definitley need to invest in a better cooler, as I'm just running the stock one! If I do though, I can't imagine I will have much room for overclocking? Would be nice to get it up to about 3.6ghz running as a quad, but not sure if thats too optimistic!

Zaim, I noticed you've got the zalman peforma cooler, would you reccomend it? Seems a good price at £26.99.

Can anyone else reccomend a good cooler for me? Cheaper the better! I've got an antec 300 case with 1x 120mm rear fan, 1x 140mm top fan and a 120mm front fan.

it's not a smart idea overclocking on stock heatsinks and fans,
i'm guessing the 78c temp is your processor? you might want to ditch the overclock until you get uprated HSF

as for a cooler, i use a arctic cooling freezer 7, it does the job very well
and it's cheaper than most
