Hi, I'm looking for some advice on this systems inability to overclock. I'm not an experienced overclocker but am reasonably confident on most of the settings etc. I have the following :
Allendale E6300 B2 revision
Abit AB9 Pro w/ BIOS v1.1
Geil 2 x 512mb PC6400 Ultra
AC Freezer Pro 7 cooler
Coolermaster case
X Pro 460w PSU
7600GT graphics
WD 250gb SATA2 drive
I'm getting reasonably cool CPU temps - 40 degrees under 100% load. 32 at idle.
I am running the CPU at stock volts. The memory at 2.1v with 4-4-4-12 timing @ 800mhz.
I've had it up to a maximum FSB of 350mhz with a memory divider set for DDR2-667 resulting in a memory speed of 875mhz, and loosened memory timing of 5-5-5-15. It starts and runs Windows perfectly fine, but locks up after maybe a few hours. CPU temps are maybe just 1-2 degrees higher than at stock speeds. It also gets errors in Super Pi.
After some further experimenting, I've come to the conclusion that anything over an FSB of approximately 300 results in errors in Super Pi and therefore quite probably stability issues, regardless of what I do with the memory, including running it at lower than stock speed. I've not tried overvolting the CPU yet, but considering people have had 3ghz and more on stock voltage, I don't think I should have to increase voltage for just over 2 ghz!
So, any ideas? Is there a big variance in these chips or am I doing something fundamentally wrong. Is anyone else using this mainboard?
Cheers
PS the PSU is about a year and a half old and is using a 20-24 pin adaptor so its not an ATX 2.0 spec. But all the voltages seem to be within spec and "rock solid" within the uGuru monitor program.
