I have been having consistent trouble going beyond 360 MHz (2.88 GHz) with my setup. I thought temperatures were the problem so I lapped my Tuniq to a hazy mirror finish and lapped the processor to a dull mirror (copper). I also didn't use much AS5. The spreader and sink are flat now and temperatures are well within safety ranges.
If I go to 3 GHz I get errors in Orthos or spontaneous reboots in Orthos. I get reboots or black screens more quickly if I quit all other programs, including CoreTemp. I've tried turning the voltages up for every part. The only thing that seems to bring stability is Gigabyte's automatic voltages setting, but that's much too hot. It certainly shouldn't be necessary to go from 1.25 to 1.39 volts just to go up 200 MHz, eh? I also worry about how many volts that setting is pushing into the chipset. I've been able to run the processor at 3.2 GHz with auto voltages but heat was a problem and stress testing with Orthos wasn't viable. I haven't tried anything over 3 GHz since the lapping. I don't think temperatures are a problem anymore. Is it my power supply being too weak? It seems really strange to be able to run everything at stock voltage (as well as the processor under stock) and then suddenly have no luck with much higher voltages after just 200 MHz of increase.
Fans:
I have a 140mm fan pointed at the northbridge/ram/Tuniq, plus a 120mm exhaust fan right next to the Tuniq. I have a 120mm intake fan and no drives in the upper area of my Antec P-180. I even removed the lower drive panel, the plastic covers on the top two panels, and the middle cage and plastic slide holders, to let the 120mm and 140mm fans suck in more air. I have a Seasonic 120mm 380 watt PSU and a 130mm silent wheel fan blowing on it. So, I have a total of 5 fans, plus the GPU fan (which is a Zalman 700 copper).
Parts:
Seasonic 380 watt 80 plus PSU. PSU fan is at 715 RPM, according to Speedfan, I think.
e2140 MO (currently 1.3v in BIOS 2.88 GHz. Says 1.248 in CPU-Z)
Gigabyte P35-D3SL 2.0
Two 1 GB sticks PQI Turbo CAS 4 DDR-2 800, dual channel running at 1:1 ratio 4, 4, 4, 12, 2T
eVGA 6800 GS PCI-e 256 MB DDR-2 stock
250 GB Seagate IDE HD 7200 RPM
160 GB WD SATA HD 7200 RPM (idles at 54C unless put right in front of a 120mm fan!)
Tuniq tower cooler with internal 120mm fan. Set to 1023 RPM.
Cheap firewire PCI card. Two port.
Antec P-180 case.
Speedfan gives me the following:
Vcore1: 1.25V
Vcore2: 1.87V
+3.3V: 3.25V (Speedfan) 3.248V (BIOS reading)
+5V: 5.00V
+12V: 4.22V
-12V: -16.97V
-5V: -8.58V
+5V: 5.13V
Vbat: 3.22
Right now, with Orthos running 8K FFT (priority 7):
Temp1: 30C
Temp2: 37C
Temp3: -2C
Local: 29C
Remote: 37C
HD0: 35C
HD1: 36C
Core0: 41C
Core1: 40C
When I had the system at 3 GHz with a voltage of 1.375 (or something similar), heat wasn't a problem but the system went to a black screen as soon as I quit CoreTemp while running Orthos with priority 9. I have tried giving the RAM more voltage and relaxing the timing to CAS 5. I get reboots, errors, and black screens. Every time I think there's a pattern, there isn't one.
