Hi,
I just put together a budget performance system based on a GA-P35-S3G and an E8400. I didn't get a choice of core when I orderred the CPU, and happened to get an E0 core, as opposed to the earlier C0 core. Now normally this would be good, but I notice from googling on OCing this mobo that generally people have only had success OCing it with F3a BIOS (eg: http://forums.overclockersclub.com/index.php?showtopic=77889&st=14). Problem for is that F3a is pre-E0 core support
E0 support was introduced with F4 BIOS.
I'm starting to try OCing, and I can so far only get to 337MHz
Beyond that it double resets the BIOS back to defaults, without getting as far as trying to start the OS. I've tried Auto settings which I thought would be fine for a mild initial test OC, and I've tried setting a variety of manual voltages and timings, and all attempts get the same result
Now I expected a few difficulties, but from previous experience OCing Northwood P4C I figured it would at least try to start the OS and BSoD, or something like that, as I approached the upper limits, not refuse to try the settings at almost no OC.
I can post details later (when I'm back at home), but I'm just looking for basic wisdom on OCing this mobo with the E0 core CPUs. The BIOS seems very reluctant to take OC settings, and perhaps I need to find just the right ones. Or is there a particular BIOS version I need. I could try F5a I notice is available. What's the risk of trying F3a with an E8400 E0? Would my system totally fail to work, or would it be something less serious I might be able to live with.
Also, my memory is rated to run at 2.2v to 2.4v, but this mobo only permits DDR2 OverVoltage to +0.4. Anyone know a way to get +0.6v from a GA-P35-S3G?
I suppose my last resort would be to get a more OC friendly mobo, but I really like the feature set of the S3G - 1 PCIE, lots of PCI slots and a parallel port are just what I wanted.
Cheers and thanx in advance, Pum.
