X5460 Mod – 3.8 GHz on Abit IP-35 Overclock Xeon

Overclocking the Xeon X5460 3.8 GHz on Abit IP-35 with 8GB OCZ Reaper RAM.

Here are the settings I use for my PC build.

A few tips:

The DRAM voltage is for OCZ Reaper (requires 2.2V) yours might be different.
If you apply the sticker yourself, be extra careful to place it in the correct position, see video.
Do not to bend any pins in the CPU socket when you cut the plastic tabs, video.
Try to keep the RAM frequency bellow the rated speed. Don’t OC your RAM.
If the NB on the motherboard gets too hot when you overclock, it will need extra cooling. Too hot is when you can’t keep your finger on it for a few seconds.
Increase the CPU voltage in small steps if you need to. I didn’t really need to do this.

Hardware

CPU: Xeon X5460 LGA 771

3.8 GHz

On Abit IP-35, if the bios contains both LGA 775 and LGA 771 micorcodes, it will not work with Windows 8.1 and higher. Windows 8 and bellow still work even if the microcodes are for both platforms in the bios.

ONLY FOR ABIT IP-35 – Moding the bios – E0

I have modded the last bios(the E0 version) released for this MB, to include only 45nm processors on platform 771, removing the 775 45nm.

This can work with other processors but I have not tested it.

As far as I know, E0 is the last supported stepping on ABIT-IP35.

The last bios that was released for this MB is considered by some to be v18 but that’s WRONG. There was an E0 version that included both 775 and 771 CPU microcodes.

These are the microcodes of the original bios:

diyrno_M630A_e0_orig_microcodes_150813

The mod consists of removing the CPUID 1067A – Plat 0,4 – that is 45nm CPUs on LGA775

The modded bios contents:

diyrno_bios_771only_edited_e0771M630A_170127

Now only CPUID 1067A is on Plat 2,6 – meaning LGA771 socket and 45nm CPU.

Download modded BIOS

This is the bios file already modded, just needs to be flashed – use only after reading all warnings bellow!

Now, please, PLEASE note that YOU ARE DOING THIS AT YOUR OWN RISK!

YOUR COMPUTER MAY NOT WORK AFTER USING THIS MODDED BIOS.

YOU ARE RESPONSIBLE FOR YOUR OWN ACTIONS!

IF YOU DON’T KNOW WHAT YOU ARE DOING STOP NOW!

THIS BIOS IS ONLY FOR ABIT IP-35 AND MIGHT WORK ON IP35-E(but I’have not tested it on that MB), — IT WILL NOT WORK FOR THE I-P-35 -PRO

If it works, let me know in the comments 🙂

  Salut!
  La mine zicea undupported processor cand biosul nu avea microcode-ul corect pentru 45nm 771. Windows 8 ar trebui sa mearga. In video apare mesajul.
  Daca in CPUZ, nu ai toate instructiunile, aia e problema… bios update sau mod.
  Sper sa ii dai de cap! 🙂

      If you see in CPUZ, all instruction sets, including VTX, you don’t need to update/mod the bios.

What CPU you were using to update BIOS? I’m planning to install X5460 on my IP35 board. Should I install Xeon first and then update to your 771 only BIOS or its gonna be fine if I use regular 775 CPU (C2D E7300 in my case)?
Thx for such a useful post.

  I did the bios update before and after installing the Xeon because I tried bioses that didn’t work.
  The MB still powers on even if the CPU is not recognized but it’s better to do the bios before installing the new CPU.
  Cheers!

the BIOS works great in my IP35 with a x5470@4ghz 1.24v , now I have to fine tune and improve temps as I want a 24×7 4ghz stable setup, it works for internet browsing and such but it crashes at stress tests. Iddles at 57C in a summer day and jumps quick to 90C under ccct benchmark!!!, I will get a cheap watter AIO and try get some extra life of this 10 year old compy…thank you!

  X5470 is what you have? Mine is X5460, checked prices now. The 70 is still a good price.
  These need serious coolers. For 24/7 it will consume a lot of power 120W TDP.
  I would check the cooler first, then increase voltage a bit but it will make it even run hotter.

Can you recommend something for Asus P5G41T-M LX V2 with X5470 that shows blue screen during Windows 10 installation?
