Finally nailed 4Ghz + turbo and power savings.
needed to connect the floppy power connector just under the PWM's to prevent my system from crapping out under sustained loads. This also completely nullified my vDroop with vDroop control disabled. (checked with DMM, voltage is solid as diamond now)
Currently 6hours into OCCT and already passed 10 LinX's and a HyperPI 32M
Ambients are 28°c, Radiator/Case temps are mostly around 30°c. Unnaturally sunny for this time of year and my room has constant sunlight, so its really cooking in here.
Core temps go up to 77°C under LinX with a Swiftech GTZ, bah... I wasn't very lucky with my Xeon (3851A), it's hot and it needs a lot of vCore. Decent VTT and memcontroller though.
PWM temps go up to 78°C under LinX load with my NB wc'ed by a EK-MAX-Acetal. (not too happy bout those, but meh, rated up to 105 so anything under 90 that's stable is good for me :p)
=> hot pwm's are also due to the 2x8800GTX right below them. Their PCB's radiate heat like there is no tomorrow and the backplates are constantly @ 55°c with nvidia's new "DirectCompute" drivers... I don't know WHAT they're doing, but they're heating up my case significantly...
I'm thinking about swapping out the GTZ for a Heatkiller LC. It's way less restrictive and also offers better temps, that might bring down my pwm temps too then due to better flow trough my NB-block... But meh, we'll seeCode:[CPU Feature Set VR Current Limit Max: Enabled Thermal Management Control: Enabled EIST Function: Enabled CxE Function: Enabled Execute Disable Bit: Enabled Virtualization Technology: Disabled ***** Logical Processor Setting ***** Intel HT Technology: Enabled Active Processor Cores: All DRAM Timing Channel Interleave Setting: AUTO Rank Interleave Setting: AUTO Memory LowGap: 17XXM (8800GTX in SLI so over 768x2) DRAM Command Rate: 1N CAS Latency Time (tCL): 7 RAS# to CAS# Delay (tRCD): 7 RAS# Precharge (tRP): 7 Precharge Delay (tRAS): 21 REF to ACT Delay (tRFC): AUTO Write to PRE Delay (tWR): AUTO Rank Write to Read (tWTR): AUTO ACT to ACT Delay (tRRD): AUTO Row Cycle Time (tRC): AUTO Read CAS# Precharge (tRTP): AUTO Four ACT WIN Time (tFAW): AUTO Ch1 Round trip latency: AUTO Ch2 Round trip latency: AUTO Ch3 Round trip latency: AUTO tREFI: AUTO Voltage Setting O.C.
