Adjusting performance beyond 3ghz on a xeon e5450
Hello... That appears to be the ultimate limit... 3.6GHZ / 10 equals 360fsb... I recall B) Q9650 here... Now I E3 1240 V2

and don't worry about trying to overclock. B)

Locate a new or used 1155 Mb and your setup will be ready.
I just upgraded my mobo to an asus p5g41t-m lx, which offers a much higher FSB wall of 391mhz and lets me add up to 150mv. My new overclock reached 3.52ghz, which is close to what I wanted. The benchmark score is a bit lower than expected since I'm currently running memory in single channel. I'm satisfied with my micro ATX form factor.
The feedback mentions that on a S775 board the FSB speed is quite restricted, currently set at 9x, which limits performance. It suggests increasing the multiplier to 9.5 or 10 for better results. Also advises adjusting the memory clock speed when boosting FSB, as mismatched settings can cause sync issues. The responder notes they’ve reset the BIOS and changed CPU bus speed, but higher voltages still prevent booting despite increased bus speed. They mention trying to raise MCH/north bridge voltage, adding cooling, or modifying heatsinks, though these changes may not yield satisfying outcomes. The user also shares a link to a video showing similar overclocking success on another board and provides their own setup details.
Alphadogg123 shared their experience with a modified Xeon E5450 system installed in a standard 775 board to replace their older Conroe E6600 Core 2 Duo. They aimed for an overclock between 3.2 and 3.6 GHz but only reached 3.078 GHz, which they found disappointing. Setting the bus speed above 342 MHz in the BIOS caused boot issues. They sought advice on potential bottlenecks. The system runs Micro ATX and uses a GA-G41MT-S2P processor patched with Xeon microcodes for SSE4.1 support. Their RAM is Corsair memory purchased years ago, which they believe might be the issue, though they're unsure if it's related to overclocking. They have three power supplies: a 550W XCLIO Bronze rated one, a cheaper ATX-500 (non-rated), and a 650W Corsair Gold rated unit. The cooling solution is a POC air cooler with fresh thermal paste, operating at 65-70°C under stress. They also mentioned using the built-in graphics since they don’t have a spare card. A benchmark link was provided to help improve performance. They suggested possible causes such as RAM or motherboard issues and expressed frustration.
The issue isn't related to RAM being insufficient, just the absence of BIOS choices. I purchased a G41 board with a micro ATX design that supports DDR3. While DDR3 was important for older SSDs, it didn't matter at the time of release. There are P45 boards with many BIOS options, but none in the micro ATX form factor.
