hi all i have a just started overclocking and have got a little way but am getting stuck now. here are the stats that i think you need.

MB - Asrock 960gm/U3S3 FX
RAM-2GB (waiting for 2x8GB 1600MHZ)-Ram running at 1.6v current
CPU-AMD phenom 560BE (unlocked to B60 3.3Ghz X4)
PSU-750W
GC- Gforce 8600GT
OS- win 7 64bit
My processor is running at 3514 MHz
frequency 200
multiplier raised from 16.5 to 17.5
core volts 1.320v (CPU-Z)
cpu-nb 1.1875v


HT link 2200

I can run prime all night with no problems. cpuid says my cputin temp is max 51c, from what i read the top end is 70c so im safe.

if i raise the multiplier to 18 i get bsod during prime but will boot. I hve tried raising volts a little but still get bsod. CPU-z says TDP is 143W is there a volts conversion.

sorry im new so all help appreciated.
 
Who told you top end is 70C? For Phenom II it's 62C and anything above 55C is not really going to be stable. It's probable that your CPU is going over 55C and crashing.

Also your HT link should be set to 2000MHz, if you have to set it to some divider because you're bus clocking make sure it's below 2000 rather than above.

Honestly with a 70mm fan on a heatsink the cooling isn't going to be stellar, especially with an unlocked quad core. You really need to upgrade to something with a 120mm fan such as this:

oh and i tested my temps of the 560 as a x2 and cpuid said the the cputin temp was around 6c more than the core temp so i worked out a approx that as per my last post 51c would mean approx cpu core 45c
 
Can you download HWmonitor and read off the actual core temps? An I am assuming you're using the AMD stock HSF which really isn't sufficient for cooling an OC quad core.

They way you describe it is telling me you're CPU is overheating.
 
i will be upgrading from the stock heatsink the the slightly larger one. although the fan is notmuch bigger that the stock the heatsink is of better quality. i will be installing this when my ram comes, and will see if it makes a difference
 
my core was 6c less that the socket temp that was after 30 mins of prime on the x2 stock. at my current setting per post 1 it maxed at 51c after 4 hours of prime
 
Right that makes sense now. Essentially all you need to do is raise the clock until it crashes and bump the voltage up if it does. You can go all the way up to 1.55V, but with the stock heatsink it'll probably top out at about 1.45V.
 
Do i nees to up the cpu-nb as well or just the cpu. I will also tomorrow try the other heatsink and fan with coolmaster thermal paste. After i fit i will roll it back to a x2 and see if there is a change on the core temp vs socket temp and then get back to you. Thanks for your help so far. Any other ideas let me knpw
Cheers
 
I'd leave the CPU-NB at stock for the time being. The only time you might need a bump in CPU-NB volts is for 1600 RAM.

I'd also actually advise against running your RAM at 1600 with a Phenom II Deneb in any case it taxes the memory controller and the performance gains are negligible. I instead run my RAM at 1333 but with tightened timings, which gives comparable performance but reduces heat on the CPU significantly.
 
my ram should have been here today but it has not not turned up. gonna do another quick stress test as a x2 write temp down then change fan and heat sink and see if there is a difference. every little helps.
