8350 + CHV FSB Throttling up

post #1 of 6
Thread Starter 
overclocked to 4.6ghz with 250x18.5
all epu and turbo stuff disabled. installed the hotfixes.
Tested with prime95 and itll pass through fine with around 65C but for some reason itll throttles up to 260x18.5 for a moment well before any high temps
Why does it do that and how can i disable it?

I'm not really sure about FSB overclocking, but maybe try disabling CPU Spread Spectrum? I have almost the same setup as you but I use multiplier x23 and 200FSB

Can't help you there then. Never had an issue with my FSB throttling 10mhz suddenly. The most I've seen my FSB throttle is like from 200.6 to 200.8 haha. You might want to consult some experienced FSB overclockers for this issue. Btw, have you tried with just multiplier and leaving FSB at 200? Does the FSB throttle up suddenly as well?

I presume CHV bios layout is about the same as CHV-Z bios, so heres a brief summary of my parameters:

AI at Manual
Ratio - 23
FSB - 200
PCIE - 100
Memory Freq - 1600 set as XMP Profile (as my RAM is 1600)
NB - 2200
HT - 2600
CPU Spread Spectrum - Disabled

Digi+ Settings:
CPU LLC - Ultra High
CPU Current -130%
CPU/NB LLC - Auto
CPU/NB Current -130%

Voltages:
CPU Core - 1.44v (this will vary depending on silicon lottery)
CPU/NB - 1.3v
DRAM - 1.51 (for stability)
The rest of the voltages are on auto

C'n'Q - Disabled
C1E - Disabled
C6 State - Disabled
APM - Disabled
SVM - Disabled

Maybe you could somehow match these? Just my 2 cents worth.
Anyway, did you update your bios to the latest?
