Hello,
I'm new to this forum and not sure if this is the correct category, so I apologise in advance.
I have a problem and any advice or suggestions are appreciated.
Here's my current hardware, I'm using an (Gigabyte) Intel GA-G31M-ES2L motherboard with an E5400 CPU and 4Gb of Corsair's XMS2 @ 800Mhz. And I'm running Windows 7 64-Bit (Not that it matters because the problem starts before the OS even loads.)
And I had my CPU at a stable overclock of 3.2Ghz with the bus at 240 and 13.5 multiplier, I recently decided to reduce my SPD on the RAM to 2.66 (It was at 3.33) and attempt to increase the frequency of the CPU even higher. So I had the SPD to 2.66 and I needed to reduce the bus back to it's stock at 200 because it would fail to boot unless I went from the stock settings first (an annoying issue but not the main problem). I then tried to increase the CPU frequency and first set it to 250, however, the system failed to boot and the BIOS reset to it's stock settings allowing it to start up, this time I only tried increasing it by 10 (from a default 200, it was now at 210) and unfortunately the same thing happened, it failed to boot. After that I decided to increase the voltage to the FSB by +0.1 (The CPU was already at a voltage of 1.4v (although I checked the current voltages from the BIOS and it seemed the CPU was only at 1.38v) from the previous overclock and the DRAM was at 2.1v, so the only thing that would of needed to be increased was the FSB) and still this did not resolve the problem, I decided to increase it to +0.2v, again it failed to boot! I was very hesitant about increasing it to +0.3v but I chose to do it anyway, the same problem occurred and it failed to boot, I gave up trying to change the settings for now and attempted to change them back to the stable overclock I had before. I reverted the voltages back to the auto settings (which changed the CPU voltage to 1.36v and the DRAM to 1.8v with the FSB at it's normal voltage) which is what they were before, changing the SPD to 3.33 was successful but once again I could not increase the CPU frequency any higher than 200, and now a new problem developed, I changed the frequency to 205 and saved it, the system rebooted and the initial screen for windows-based systems showed up detecting the memory and HDD's etc. and also displaying the current CPU frequency, multiplier and clock speed, this displayed the frequency at 200, but, when I loaded the BIOS it showed the CPU frequency was enabled and at 205. I restarted the system and this time booted into Windows, I ran CPUZ to check the bus speed from that and it was also stating that it was at 200. I restarted the system, launched the BIOS and it still said it was at 205, I then increased it to 210 and the same thing occurred, the bus speed didn't change but the BIOS states that it has. I changed the frequency to 250 and rebooted, this time the BIOS had reset meaning that it couldn't boot with the previous settings, so I changed the frequency back to 250 with an increase of +0.1v to the FSB, the computer stayed turned on but the screen had turned black (it had a signal but nothing was being displayed) I left it for 10 minutes and still nothing was happening, I decided to turn off the system by holding the power-button. Since then I have been unable to successfully change either the CPU frequency or the voltages without the system "freezing".
I have tried to resolve this problem by updating the BIOS directly from start-up (using Qflash included by Gigabyte in the BIOS) and that has not helped, I have tried 4 different versions.
I've also tried many different settings throughout the BIOS including different SPD multipliers, again to no avail.
I'm really at a loss as to what I can do, if anyone has any insight or help they can give me I would highly appreciate it!
Thank you in advance.
P.S. Sorry for such a long thread.
