Gordy!

I think a GA EP45 UD3P would have been a good option also, it's a beast at overclocking X5470, but you already have your board so...

Using information from here I've been able to implement the upgrade from Q8200 on a P5QL Pro to an E5450 Xeon while using 8Gb of OZ Reaper DDR2 RAM. I haven't tried to push much of an overclock. I had it booted all the way into windows a few times with 3.6Ghz and 3.1Ghz with less RAM, but wasn't able to get it stable with the full 8Gb until I tried the settings shown above. Maybe I'll push it a bit later on.
Thanks for this thread!

Hey, I have a question to ask: Have any of you faced issues to boot into windows 10 because of FSB overclocking?

I can't seem to push my Xeon E5450 to 4.7Ghz because when I do, it always says ntoskrnl.exe (or whatever else.sys, it's random files) is damaged. Anything over 520 on the FSB gives me this error. Tried 1.5V on the MCH (which you shouldn't do but, might as well give it a go) but didn't solve anything, nor did VTT at 1.46V, nor did Gigabyte's AUTO voltage settings that completely exaggerate them. Clock Skewing just makes it crash at 50ps and 100ps doesn't even boot.

Now you'd think I just simply broke my windows install, but no, 4.6Ghz boots fine. RAM is running at 1040Mhz and it's a 1066Mhz kit, I have it at 2.28V and still fails to boot. Tried loosening up the timings, nothing. Still hangs at the boot screen with the same error message. (system doesn't crash, just refuses to load windows). CPU is at 1.68v (because my board doesn't support LLC).

I'm kind of lost here. Have had a Google around, nothing seems to help.

Specs:
Intel Xeon E5450
Gigabyte EP45-EXTREME
OCZ Gold 1066Mhz 5-6-6-15
Raijintek Tisis @2600rpm
Sapphire HD 7950
LEPA MaxGold G800M (800w) 80+ Gold
Windows 10 Pro 64bit

Thanks in advance.

you can try to push 3 things for more stability:
1) increase MCH to 1.62V
2) increase PLL voltage to 1.64V (those 771 xeons love PLL)
3) if your boards has thoe GTL reference ****, set em up at x635 and x670 multi (this help a lot when you push high VTT voltage)

if any of this or combination of all of em doesnt help, well, then you are screwed.
pushing over 500 FBS for stable use depends more on silicone lottery than anything else

Hi,

I have a Dell Vostro 230 with a 775 socket motherboard and I modded a Xeon x5460 to use it with this motherboard. I also added the corresponding microcodes to the BIOS which is an AMI BIOS.
The cpu is correctly posted and works perfectly but I have a problem with the scaling governor.

The scaling is perfectly done in Windows 7. I can monitor the multiplier using CPU-Z and it changes regularly keeping the temperature around 40 degress if no operations are done, even lower.
But when I use debian, the multiplier seems to be always at the maximum value and the temperature is around 10 or 12 degrees higher than windows.

I installed cpufrequtils but apparently none of the drivers is compatible with this cpu. I tried manually to load the drivers I think might work with this CPU using modprobe: acpi-cpufreq and p4-clockmod. but I always get the same output:
modprobe: ERROR: could not insert 'acpi_cpufreq': No such device
modprobe: ERROR: could not insert 'p4_clockmod': No such device

Also there is no directory called 'cpufreq' in /sys/devices/system/cpu/cpu0 (same for cpu1, cpu2 and cpu3)

Does anyone have any clue of what is going on? There are no compatible drivers for this cpu? It sounds to me a bit odd as the scaling works fine in Windows.

Thanks.

I bought a Dell Optiplex 380 for $20. I picked it because of the G41 chipset and 120W CPU support. I've seen X5460 running in them at userbenchmark.com This gets me past the Q9650 limit most Optiplexes have.
So far Q9505S 340fsb 2.9GHz., 8GB DDR3 1066,GTX 1050TI, 120GB SSD. BIOS A05 (to avoid the digitally signed A06,A07).
I modded the socket, I have a couple of X5470s and the sticker. I see a modded BIOS at BIOSmods.com but it removes LGA775 support.
I would like to get X5470 microcode added, and if possible QX9650 support also. I will probably pinmod a Q6700 to 3.33GHz too, so I don't want to lose LGA775 support if possible. The C2X issue isn't just 130W related, it rejects the X6800 75W 2 core also.
Here's a link to the BIOS download if anybody wants to take a look at it. Be careful it comes with a loader that will install it from Windows if you let it.
Perhaps best dissected from a Linux live DVD.
https://downloads.dell.com/bios/O380-A05.EXE

I posted something here about BSEL, and VID pinmods being the same for LGA771 and 775. I did find out that not all LGA775 use the same Voltage chart. The older chart for 65nm chips is called VR10, the newer one for 45nm is VR11. There are probably older ones for LGA775/771 P4 chips also.
They can be seen here. Pg. 47.
https://www.intel.com/content/www/us/en/power-management/voltage-regulator-down-11-0-processor-power-delivery-guide.html
VID7 is not listed in VR10, VID6 functions very differently in the 2 charts. in VR10 it alternates, In VR11 it has large blocks of settings.
Between that and the different base Voltages you may encounter this means you can't just look for VID maps to copy. You will need to know your base VID and map it out, then get the correct chart and plan your mod.

I bought something today that might be of interest. 2-2 core X5270 3.5GHz Xeons for $14 each. 10.5x 1333fsb.
This seems to be the same as the mythical E8700 that Intel never released. There was a 43 page thread about somebody getting one of these back in 2010, He said it went 4GHz on the stock 1.18V. I'm going to try an OC on a 2 CPU workstation so they'll be interesting there. But I think I'll try one in an Optiplex 380 first and see what I can get out of it.

Will keep these in mind if I give it another try, for now the board is back on the shelf. Haha. Thanks mate.
