I thought E7500 2,93ghz would easily go beyond 4,0Ghz but it stopped at 3,9Ghz!
3,70ghz at stock voltage: 1,3625v
3,90ghz needs 1,400v
3,96ghz needs 1,4625v
4,00ghz is not stable even at 1,500v
Its a pity considering that I can push my MB bus to at least 400mhz which would give a OC of 4,4Ghz!!!
Can you give me a hint?
Here is my latest stable configuration:
At 4,0ghz, full load = 59°C with RealTemp (still long way to the 74°C limit)
Prime95 does not give any error during that time. Computer simply reboots after lets say 10min of full load!
WHAT DO YOU THINK IS LIMITING MY SYSTEM?
My computer:
E7500 @11*360mhz Vcore:1.46v, “+12vâ€=12.51v
BUS: 360mhz (MB can do 390mhz+ tested by me previously on E6300)
RAM: 2.1v, 360mhz, 1:1 ratio, Latencies [auto] (all within manufacture limits)
FSB: auto (it has been in [auto] in my previous OC on E6300, which had higher FSB)
MCH: 1,60v (have tried the max 1,65v of the MB and didnt help)
ICH: auto
PCI-X and PCI are locked at 100 and 33 respectively.
MB = P5W DH Deluxe, latest bios2901 (people have reached 420mhz of bus speed on this MB, I have manage 400mhz on my old E6300 and now I cant pass 360ghz on E7500)
PSU = LC Power 550w, Could that be the problem that causes the computer to simply reboot? Here is the rest of the hardware:
HDD = 2x western digital velociraptor on Raid 0 Matrix
HDD = 1x Maxtor 320gb
VGA = Nvidia GeFoce 7600GS 256mb passive cooling (I am not a gamer, I am a photographer that needs a fast single core to work on LightRoom with good response)
DVD = 1 plextor
Sound = 1 creative 5.1 player (a cheap one)
TV = Leadtek 2000xp
Thanks in advance!
