Here's my best compromise overclock / Temperature
- E4300 @ 9x340 FSB = 3060 MHz vcore 1.525v bios (1.48v real)
- Zalman CNPS-9700AT + Arctic-cooling MX-1 compound
- ASUS P5B Deluxe bios revision 0910
- CORSAIR 4x 512 Mb DDR2 800Mhz (PC2-6400) [TWIN2X1024A-6400] 1:1 ratio (680 Mhz, 5-5-5-15-6): I didn't try to tweak it
- TAT Idle 40-43°, Load 62-65°, Ambiant 25°
All other settings are set to manual on lowest values (vNB, vSB, vFSB)
vDDR is 2.0v
Orthos stable 6h, and will validate a >16h today
Cooler is set on performance mode, so not blowing air at maximum speed
I know my vcore is high, but why not?
My temperatures are also some high, but being on air, for that vcore and speed and an avarage E4300 chip...
I'm also rock stable Orthos 16h 9x326 = 2934MHz, vcore 1.45 bios (1.40 real), DDR2 800 @1:1 (652MHz) with much less heat
Notes on the problems I have dealt with:
- ASUS bios revisions 1004 and 1101 won't POST my stable overclocks on bios version 0910
- No way to overclock my RAM any near the 800MHz
- I had temperature issues at first and had to reseat my HSF 3 times without 1°C temperature gaine. The 4th time I reseated it using more MX-1 compound (spread a virtual layer of compond on the HSF and CPU surface using a lint free cloth, thin line from MX-1 tube on the 2/3 CPU large in the middle, gently put the HSF on CPU, tighten it, twist it 10 degrees 2-3 times). After posting, I got a 10-12° drop on load for same ambiant temperature (on lower fan speed, so maybe even more drop in temperature). For a 1.45 vcore I was at 66°, now I'm on 63-65° TAT for a 1.525 vcore (Temperature at a 1.52 vcore was 77°)
Final thoughts: I'm rather lucky since many E4300 owners never reach 3GHz. I'm less lucky than thos reaching my same temperature for a much lower vcore.
Questions:
Any tip to lower my vcore to achieve that speed?
Am I safe to use on a long term such a vcore / temperature?
Many thanks
