Do you have a functional BSEL tape version for the Q9500 CPU?
Do you have a functional BSEL tape version for the Q9500 CPU?
I've checked the area, but most items focus on the Q6600. The motherboard is an HP 3048h.
Actually there are 2 variations of the tape mod. One uses metal tape to run traces. the other just blocks one pin with electrical tape. here's the old one.

There are no experts on OCing OEM computers. There is no forum where 50 guys have done this before. There are 50 forums that will telll you it can't be done.
The only reason I suggest trying t he 400FSB mod is I saw a Dell Dimension 780 Q45 chipset running Q9650 @ 3.6GHz, and the only way I know to get there is BSEL 400.
The experts will tell you...
The BSEL mod demands that the MB accommodate a higher FSB speed than intended. There are several explanations for why you're encountering the Q6600 frequently. Previously, it was half the price of the Q6700, making modding the Q6600 a practical solution to its elevated cost. Today, the Q6700 offers superior performance.
Your Q9500 is already at 333/1333fsb and cannot exceed that unless your MB supports 400/1600fsb (which is Xeon territory). Most OEM chipsets also impose a 95W CPU limit, preventing operation above that threshold. This restriction excludes the CORE2 EXTREME models.
The Q6600 operates at 9x266fsb = 2.4GHz, so BSEL should be set to 9x333 for 3.0GHz, matching the Q9650 but with less cache. The Q6700 runs at 10x266 = 2.66GHz, making BSEL 10x333 for 3.33GHz. All Q6700 models represent a better G0 option. The Q6600 typically runs at B3 or G0, and these configurations require significantly lower voltages.
If you need additional voltage stability, Throttlestop software can assist from Windows. Regarding your query—yes, on a workstation MB, you can BSEL it to 400fsb for up to 8.5x400 = 3.4GHz. I've observed a Dell Optiplex 780 running Q9650 at 3.6GHz (9x400-3.6GHz) on userbenchmark.com. Sometimes chipset manufacturers include hidden support for higher bus speeds, though this remains undisclosed due to the 95W limit. It may also be that insufficient voltage was initially provided, leading to failure. Perhaps you might be fortunate like I was with my Dell Dimension E520. Please check the link in my profile for more details.
William P explains the reasons behind the popularity of certain models and their technical limitations. He notes that the Q6600 was a cost-effective alternative to the Q6700, while the Q9500 is limited by its MB's 333/1333fsb support. He also mentions that OEM chipsets usually cap CPUs at 95W, affecting performance. The Q6600 offers better stability and voltage options, and BSEL settings can be adjusted for higher speeds. He suggests checking software like ThrottleStop for further optimization and asks about recommended programs if overclocking isn't feasible.
The OC I tried works only with an unlocked CPU. If your motherboard supports more than 95W CPU, it might be possible. TS can adjust voltage without needing the unlocked CPU. There are older FSB programs that modify the FSB settings, but they don't handle Volts SETfsb or ClokGEN 2. TS does Volts control, but not FSB adjustments. You could attempt to combine them if you wish. I prefer Throttlestop paired with Core2Extreme. The FSBs didn't function for me, though some users reported success.

I'm not used to HP products, but I'm a Dell OC. I experimented with different setups until I found what worked. In my case, the system supported older Pentium4 and PentiumD CPUs, which gave me 130W and 3.73GHz already. This enabled C2X chips but not BSEL. With your 1333fsb setup, you could add the Q6700 BSEL with TS to adjust the voltage if necessary. It might still run. You might be able to lower the voltage slightly and try the 333 to 400 BSEL on the Q9550. It "shouldn't" work, but my Dell shouldn't be running at 4GHz either. If it does, you'll likely be the first like me. Just a bit of extra code might be needed—they didn't bother fixing it.

The experts will tell you only the X48 chipset has 400fsb. But X38 already had it. There just weren't any CPUs that needed it yet. So somebody somewhere tried it and it worked. Every expert said O/C ing my E520 wouldn't work. I'm #2 at CPUz with it now.
I'm still learning too. i found a laptop OC page. Since laptops are almost all locked with no MB options they got pretty creative over there. There is a hardware mod called a "TME unlock". I think this might allow the 400fsb BSEL to work. It requires cutting a pin on the PLL chip. All their posted results are laptops though.

Thanks but I don't think its worth the effort and impractical.
