Disabling SpeedStep not working

[xCxStylex]

I'm trying to overlock my E8400.

This is my MB and Ram

In my BIOS, I've disabled both Intel SpeedStep Tech and also "CPU TM function," which was suggested in my Asus MB manual but CPUZ shows my multiplier going between 6 and 9 often, 6 when idle.

Isn't it disabling this supposed to stop windows from lowering the multiplier when idle, or did I completely miss something?

Or is some Asus utility that I installed (I installed just about everything that came with the MB and also updated them) taking over when windows loads up?

Any ideas as to why the multiplier won't stay at max? (9)

Disable C1E support also.

Don't disable CPU TM (Thermal Monitor), that's what saves your CPU from dying if it gets too hot.

Disabling C1E worked, thank you.

Ooh, thanks for the tip, I need to re-enable CPU TM :X

I ran a prime95 torturetest for about 2 hours and my cpu went from 30-33 idle up to 56 C before I stopped it. Seems to be ok, thank you for your tips

no DON'T disable thermal monitor, ever!

Disable the other two, they are good to disable, the thermal monitor auto down clocks your CPU if it goes over 105 degrees Celsius, and WILL save your CPU, there is no reason to EVER disable it, even if over clock.

The ONLY POSSIBLE reason to disable it is if you have a faulty CPU that incorrectly detects its own temperature and engages the thermal protection incorrectly (never heard of one, please not that if you get a wrong temp reported inside windows that is a different type of thermal monitor, and it is also usually a software issue, not an issue in the hardware).

Sorry to revive an old thread, but I am having similar issues.

So before I get into it here is my build:

- Intel Core 2 Quad Q6600 Kentsfield 2.4GHz LGA 775 Quad-Core Processor Model BX80562Q6600
- ASUS P5KPL-AM/PS LGA 775 Intel G31 Micro ATX Intel Motherboard (cheap, I know)

- FSP Group Blue Storm II 500W ATX 2.2 SLI Ready Active PFC Power Supply
- Kingston HyperX 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Desktop Memory
- Vista 64 Ultimate SP1

In an attempt to prevent my Multiplier from changing I have made the following changes:
- Selected "Higher Performance" Power plan in Vista's Control Panels
- Disabled Intel Speedstep Tech in BIOS
- Disabled C1E support in BIOS
- Set CPU Ratio Setting to 9.0

I have overclocked the CPU to 2.7ghz. It idles at 40deg C. When I stress test the build the Multiplier is reduced from x9.0 to x6.0 (2.7ghz -> 1.8ghz) as shown in CPU-Z. This happens when the cores reach about 60deg C (CoreTemp 0.99.4 and RealTemp 3.0). It will then bump back up to x9.0 when the temp has dropped down to 53deg C or so. How do you stress test a build when the multiplier will just adjust downward to make it stable?

The only thing I can think of is to disable CPU TM Function. I have received mixed directions on whether this is a good thing or a bad thing to do. Some guides say that this must be disabled to OC properly. Others such as in the posts above, say never to disable it. At what temperature is CPU TM Function supposed to kick in? 60C seems a bit low (and no where near what the 100C stated above) for it to start throttling. Right now I simply can't do any meaningful stress testing as the second the cores get to 60 deg C the multiplier gets cut from 9 to 6. See my dilemma?

Any Ideas from the community?

To see if you are thermal throttling, load RMClock. It will show you a graph when you throttle. You should not be throttling at 60C. If you are, something is seriously b0rked, and you might need a CPU RMA.

Disable EIST.

EIST (Intel Speedstep) is disabled.

I decided to disable CPU TM Function and stress test....I let Prime64 run for 1.5 hours and was at a steady 67C. No errors. I will be doing heavy x264 encoding on this machine which will probably max out all4 cores for several hours. Do you think 67C is too hot?
