Looking for assistance in boosting the X5650 processor using an Intel DX58SO?
I recently assembled a PC using an x5650 and an Intel DX58S motherboard. Overclocking isn't possible for me at all. Whenever I attempt it, it fails to boot and reports instability. The cooling system is excellent.
I suspect the issue relates to the RAM configuration—specifically, a 12GB module with CL 11 1600MHz. The automatic profile lists it as CL 9 1333, but changing it to CL 11 1333 or using 1600MHz doesn't resolve the problem. Even leaving it at the automatic profile and attempting overclocking fails. The RAM operates at 1.5 volts.
I cannot enable the CPU multiplier (capacity is 20), so I'm restricted to using the base clock only. I tried setting the CPU voltage to 1.3 during an overclock attempt earlier, but it would have needed to be adjusted further down.
All power-saving features are turned off; I've configured it for low Vdroop. The only adjustable voltage is IOH Voltage, which remains at the default 1.1. The BIOS is up to date.
Consider enabling the XMP profile to address the RAM configuration issue. The 1.325V setting definitely leads to instability since it's under-voltage; also, the voltage should be increased rather than decreased. Your RAM is rated at 1600MHz and 1.5V—if you need to adjust manually, try 9-9-9-27 or 9-9-9-28 (not 9-9-9-24). For 1333MHz at 1.525V, if instability persists, raise the voltage by 0.025V until the system runs smoothly. It's recommended to use the XMP profile instead.
When overclocking an Xeon CPU, you should not rely on the CPU multiplier setting; instead, focus on adjusting the BCLK value. The Xeon model also supports speeds up to 1333 MHz, meaning you can't go beyond that, but increasing the BCLK can allow you to reach around 1400 MHz. I included a link with instructions for overclocking the Xeon (specifically the E5620) so you can achieve the best results.
Adjust RAM frequency from 1333 to 1066, then raise BCLK to near 1333, turn off auto profiles and manage manually. Boosting BCLK by 10% should result in around 1173MHz (with RAM at 1066), while a 20% increase brings it to ~1280MHz and 25% to ~1333MHz.
what cin19 mentioned about x2
i own a 5960x and couldn't overclock until i adjusted the ram to 2133, which matches the maximum supported by intel according to their specs—i didn’t realize that when i bought 3200 oc ram. after setting the ram to 2133, i could overclock up to 4.2 and might go higher, but i’m content at 4.2—it’s quite stable there.
The bios doesn't correctly compute the frequency, displaying a value around 3.8 instead of the expected 3.6. It seems to use the base clock multiplied by a factor.
It seems the intel MB might not officially support the x5650 despite having lga1366. You can run the CPU but the MB will treat it as a different processor. Check the compatible processors page for more details. You might need to update the chipset driver for sensors so the CPU-Z can read the correct specs. The driver may not be suitable for your MB, but you can still install it. Remember to add base clock * multiplier.
Updated the chipset driver with the official update for this board.
I'm still facing issues with stability. The voltage is set to 1.325, but CPUz reports values around 1.266/1.277. It's hard to get anything consistent.
I've tried different RAM options, manually adjusting settings to 9-9-9-24 at 1.62v and keeping the clock under 1333mhz. This helps with overclocking in Windows but causes crashes afterward.
