PK5 E5450 Overlclock Issues

[Ashy98]

Just put a budget system together for my bro to play some older games

Specs are -
Mobo - Asus p5k (Latests Bios With Injected 771 Microcode)
Cpu - Xeon e5450 (C0 Stepping)
Gpu - GTX 460
RAM - 6Gb Corsair XM2 800mhz 2x 2GB 2x 1GB
PSU - OEM Delta 500w
OS - Windows 10 Pro 64Bit
Cooler - Generic Tower Cooler

I'm having issues with getting the system to post with any overclock at all in windows 10
It doesn't mater how much voltage I give it just doesn't seem to like any voltage & fsb increases I've changed many different settings increasing other voltages messing with ram timings etc And no change, however before I initially installed windows 10 I was running windows 7 pro and I was able to boot into windows 7 fine with overlocks did some cinebench runs and it seemed to pass great around 65c on the temps I would have obviously ran thurther stress tests to ensure the overclock was stable but reverted back to stock settings in order to get windows 10 installed and proceed after that .....I had a boot cd laying around so dialled the overclock that I wrote down booted from that did Memtest86 first with ram at 801mhz CPU 3600mhz which passed with no errors ...also booted into windows xp from the disk and ran some tasks in Aida64 which all passed...which leaves me to believe windows 10 is the issue?

Any help would be appreciated
This is my first post so really hope I got it in the right section

Cheers
Ash

Was going to say ...

P5K uses the P35 chipset which IIRC isn't so well suited to overclocking the 771 Xeons, though some people do manage to get them up to 4G+.
A P45 based board is what you really need to get the most out of the chip.
Same goes for the processor really. E0 stepping is your best bet for high frequencies and lower power consumption.

... Until I read your post properly and noticed Windows 10 may be the issue.

Only thing I can suggest is reset the CMOS, plug in the minimum number of components, eg 1/2 sticks of ram, video card, one hard drive/SSD, give it a fresh install of Win 10 and go from there.

FWIW, I'm on Win10 Pro 64bit here with an E0 stepping X5460 and an Asus P5Q Pro (P45 chipset) and have no problems overclocking it well beyond 4G.
Only issue is managing the power consumption/heat/temperatures as you go beyond ~4.2G
It's actually down at 3.6G at the moment just to avoid spinning up the PSU fan in some more intensive games.

So installed a fresh copy of windows 7 running everything out of the case posted at 3.4ghz @1.3v ran cinebench 5 times everything seemed fine temps weren't going over 65c started prime 95 up did large FFt test instant fail on 2 cores. So took the chip out stuck it in my 780i Sli board hit 3.6ghz easily tried the chip that was in that pc a q6600 and began to overclock made it to 3ghz did prime 95 everything was good after a hour ...so I'm going to put it down to the board being weak as you said i found out it has only 3 phase power regulation :/ oh well...worth the £5 I payed for it was better than using a OEM board cheers for the help anyway
