Why? The limit is 70 for Tctl and Tctl is way more accurate. Who cares what the *real* temperature is?

I never rely on technical documentation, but rather user experience of the masses. Myself and some other uses noticed throttling down to the x7 multiplier when the socket temperature reached close to 70 C even if the individual core temps were still only at high 50's.

- Different frequencies across cores: APM is still active, update BIOS or use Overdrive on every reboot to enable/disable
This one was solved early on with BIOS updates on most boards.

- Frequency throttling to ~1.7 GHz for split seconds in TMonitor: VRM is getting hot and throttling speed
Seems to be an issue on a few boards that have poorly designed heat sinks on the VRM's like the Fatal1ty 990FX. It's been reported that some lower end boards don't throttle even with high VRM temps though and simply crash.

- Multiplier dropping to x7: Socket temp is high and throttling CPU
This problem was solved as soon as I put a fan on the back of my motherboard socket that dropped the temperature by 10 C.

- Black screens or crash during Windows loading: Might need more voltage on core
Issue was always solved by upping the VCore

- Screen freezes but no corruption: CPU-NB, HT, VDDA voltages need tweaking
Issue was always solved by upping the other voltages

- Screen corruption and crash: High core temperatures and/or needs a voltage bump on DRAM
Normally just needed an additional voltage bump. these crashes usually happened when stressing the memory in Prime95 or Linpack testing. Upping the VDRAM helped sometimes.

This is my 24/7 oc wich im very pleased with,i will soon replace the H100 ( because of the grinding noise ) for an EK kit to try and get a better oc,especially since i want to bump up the nb speed aswell but at stock it already gets pretty warm.

Btw i love this cpu + mobo,ive never been able to oc a cpu this high,easily and keep it so cool,except for the NB.

CPU Cooler Thermalright 140 True Spirit with single fan
CPU overclocked base to 4530 Mhz and turbo boost to 4830 Mhz on 1.413v
FSB 2317 Mhz
Ram 1680Mhz on 1.65v (8gig)
NB 2317 Mhz
LLC on NB set to medium (50%)
LLC on CPU set to Optimised
CPU core temps do not go over 40c
CPU socket Does not go over 50c
MB stays around 38c
VRM spread is on
Everything else in the Cool n Quite section is on. TPU and EPU is on
Game FPS increased a few frames with this overclock from the standard over clock I had from 4600mhz with turbo off. System boost faster and loads programmes and games faster with this overclock. (Interresting)
