Hi..
I've learn overclocking for about 2 weeks, and now I finally bought a computer for experiment with this specifications :
M/B : Gigabyte P35-DS3
CPU : Intel Core 2 Duo E7500 @ 2.93 Ghz
VGA : Nvidia GeForce GT 320
PSU : Gigabyte 450W
RAM : 2 x 2GB Kingston @ 800 Mhz
HSF : Zalman (I think good enough)
HDD : Seagate Barracuda 250 GB
OS : Win 7 Ultimate 64-bit
All of them are used items, so its cheap..
When I start overclock, I change the clock ratio to 11, cpu host fequency to 316, PCI-e Freq to 100, and memory multiplier to 2.00. So the clock gonna be 3.4Ghz. (All voltage normal)
But when I save this to bios and reboot, the psu seems like failed to power up for 1-2 times(not immediately) and success on the 3rd time. When I go to bios again, the "CPU host clock control" become disabled which make my CPU host freq become 266(default). I've tried to lowering the CPU host freq to 306, 296 but the results are same.
I tried to increase voltage, "DDR2 Overvoltage control" to +0.2V, "PCI-e Overvoltage" normal, "FSB Overvoltage" to +0.2V, "(G)MSH Overvoltage" to +0.1V (I use this settings after read others problems) the Cpu Voltage to 1.1375V (CPU host freq on 296). I got same result on 1.1375V but when I change the Cpu Voltage to 1.5000V the psu powered up like normal but it just stuck on a black screen after bios post message.
After do some tests on voltage control, I manage to see the windows logo(first loading), but after that it comes a sec blue screen and restart.
So I jump to conclution, the first problem (psu not start immediately) was caused by low CPU Voltage, and the second problem (blue screen, failed to load windows) was caused by memory..
I've read some people can reach high clock just with stock voltage and also when I test overclock for the first time on ASUS P5QPL-AM with E7500(not the same processor), 2x1GB 800 RAM, 480W PSU, stock HSF, with no voltage change at all (CPU Volt changing not available), it can reach 3.4 Ghz (11 x 316) and seems stable on windows(32bit).
Why I can't reach high clock on gigabyte?
- My PSU isn't good enough?
- Problem with the M/B or CPU? (because used things)
- Wrong settings?
- Memory timing?
I read gigabyte motherboard can reach higher clock better than ASUS. Am I right?
Can someone help me with proper "enlightment" to straight up things?
Hahaha..
Any help will be really appreciated..
Thanks..
