Hey Everyone,
First time OCer here and I would greatly appreciate any help/advice that you folks could provide me. I recently managed to get my hands on a Core2Duo processor that someone was getting rid of. So I decided to build myself a cheap new rig with it. Let me start off by detailing my system specs:
I am aware that the memory, motherboard and heatsink are "budget" components, so I shouldn't expect too much in the OC department. However, I'd like to find out if I am at the limit of my Mobo/Memory combo or if I can do better.
As of now, I have managed to get my FSB (CPU Frequency) to 400MHz, thus pushing my processor to 8x400 = 3.2GHz. My RAM is set to 1:1 (2.00B multiplier, ie, the 333MHz strap) to achieve the native 800MHz rating at 5-5-5-15. I have posted the details of my BIOS setting below but the main change that I made was to set Vcore to 1.35V.
My system is Memtest86+ stable (10 passes), Orthos Prime (9 hours) stable as well as IntelBurnTest stable (8 passes, Maximum Setting).
CPU idles at around 30C and under Orthos Prime/Most other applications inducing full load it goes up to around 53-55 C. IntelBurnTest is much harder on the CPU and brings it up all the way to 69C.
While I am very happy with what I have achieved so far (and my current system performance), I do feel that I could get a bit more out of my CPU/RAM. However, whenever I try to increase my FSB past 400MHz (I lower the CPU multiplier to 7 to prevent the CPU affecting the OC), I start having issues such as Memtest errors or failure to bootup. Am I basically at the FSB limit of this mobo or are there some settings that can help eke out higher FSB speeds? 425 MHz fails to post, and I have tried changing between B and D straps with no luck. While it could also be a RAM limitation, a bunch of Newegg reviews had people running this RAM at 900MHz at 5-5-5-15 without any trouble. I figured that 850Mhz (425 FSB) shouldn't be too much of an overclock so I do feel I am being limited by my mobo.
Thanks in advance for your help and suggestions.
Cheers.
