[MOD] LGA775 Support For LGA771 Xeon CPUs - Page 1183

post #11821 of 12058
Can you please stop creating all of this off-topic?! Makes no sense at all bringing a complete different platform over 771@775, specially if it is AMD... You have loads of threads on AMD side and if not just create one...

In meanwhile I was able to decrease my Vcore and get my E5450@4.0Ghz with 1.28V.... Dont need to push it further for now...

As for your PentiumD, lol, Annnnndd? Did U miss my post a while back about my dell ? http://www.overclock.net/t/952543/how-long-will-we-775-brothers-stick-together/750#post_25382361
http://www.overclock.net/t/952543/how-long-will-we-775-brothers-stick-together/750#post_25405293 <--- Compaq upgrade from celeron to PentiumD to E4700 with Windows10 free upgrade 64bit.
For the record,I believe the requirements I quoted came from a post for windows 10 pro. Also,I've since found requirements as low as 1GHz,sse2,XD,&PAE along with upping ram to 2Gb for anniverary edition.rolleyes.gif

I wanted to point out that Xeon Clovertown wasn't first CPU to support VT-x since my Pentium 965 already has it (CPU-z) smile.gif and yes, I did missed Your post on Pentium D update you did - but "so what ?".

As for new "minimum requirements" :
1) There are no 1GHz CPU's with SSE2 only support (even Atoms don't go that low and low power stuff that does has SSE3+ at least, ARM - of course - can't support SSE).
2) SSE2 by itself is also false, since there is no way to find out if it's true.
There are no "XD capable" PAE only CPU's, without at least SSE3 instruction set support (Prescott).
I think SSE2 requirement is used out of convienience (ie. compiler used), and not hardware that is/was actually available.

Basicly : Guys who decided on them don't know what the world looks like (the PC hardware one).

Minimums.... As in @ least sse2 (sse1,sse2,...GEt IT??) Yes,there are earlier xeon's.The cloverton's were a mistake. for better info, here's a fair listing.https://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#.22Irwindale.22_.2890_nm.29
Granted,1GHz nowadays have newer instructions,such as the AMD C-50 that's in a notebook I have running Windows10 home 64bit. LOL, But you can see WHY they had to put the 1GHz limit? As for PAE & SSE2, those 2 requirements keep the AthlonXP cpu's from being used again. LOL, lots of people still use them for emulators and DOS boxes for old gaming. (some flavors of linux are designed for those lower specs.) http://www.cpu-world.com/CPUs/Bobcat/AMD-C%20Series%20C-50%20-%20CMC50AFPB22GT.html
Now,I've said MORE then enough on this subject. Who needs help with a mod??? smile.gif

"Minimum" means you can run it on SSE2 CPU, that supports other features.
Problem is, there are no SSE2 only CPU's to check if that's true.
If that's the case, how can they know if it will run on procesors that doesn't exist (SSE2 + PAE + XD-bit + CMPXCHG16B + ) ?
Having SSE2 as requirement when only SSE3+ capable CPU's are on market that support other required instructions... what's the point of that ?
I think they should simply go for SSE3 limit and be done with it, because the easier to explain XD-bit requirement "kills" both Athlon XP and early Pentium 4's (Willamette/Northwood, both P4's have SSE2 support by the way).

Yes, I see that C-50 and I feel sorry for you, but that's why I think they should go for at least 1,4GHz for minimum CPU clock speed.

In short : Minimum spec M$ cooked up is confusing and that's why I hate it so much.
I hope you understand, EOT.

Well, I posted a week or two ago requesting help getting microcode for my Xeon inserted into a Lenovo ThinkCentre M57 BIOS. Got some very helpful pointers and I'm happy to report I've finally gotten it working, and figured I might as well share how. I was originally going to give up and just deal with the missing functionality, but I discovered Windows 8.1 refused to boot with it in its current state and decided to try again.

First of all, I recommend that anyone doing this with a ThinkCentre avoid using the Phoenix BIOS editor. I don't know why, but my M57 didn't like it at all (even though all I changed was the microcode, and no errors/warnings were reported in the build log). It flashed OK but no matter what it would freeze at boot displaying "INTEL (r)Q33/Q35/G33 PCI Accelerated SVGA BIOS, DECOMPILATION OR DISASSEMBLY PROHIBITED". The standard Phoenix BIOS recovery tutorials did not work (Win+B had no effect), but thankfully Lenovo published official instructions for recovering the BIOS of a ThinkCentre and that got things working again for me: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&LegacyDocID=MIGR-45385

What did work was simply using a hex editor on the official BIOS and overwriting the microcode for another (unnecessary) CPU that was the exact same size. It was a simple matter of using intelmicrocodelist.exe to determine the offset/size of the donor/destination microcode and copy/pasting appropriately (in overwrite mode). Flashed it using phlash16.exe and, to my disbelief, it worked!

Now Windows 8.1 is running fine, and I have all the previously missing functionality (like VT-x) enabled. There's probably a better way of doing what I did, but I'm just glad I got it working at all without bricking my motherboard.

Attached is the modified BIOS I used, figured I might as well include it. image2R.zip 750k .zip file



EDIT May 2015:
I've noticed a few people may have gotten confused by my CPU-Z screenshot and thought I was running an E5420. The real CPU is listed lower under "Specification" as an X3323.

No microcode will be able to make the 5xxx series Xeons work on the M57.
The M57 is the Intel Q35 chipset, and according to this compatibility chart only the 3xxx series Xeons work: http://www.delidded.com/lga-771-to-775-adapter/2/#motherboard-compatibility

---

2nd EDIT Jan 2016:
A couple people contacted me wondering which version of phlash16 and what parameters I used, and unfortunately at the time I couldn't recall (while I was messing with this, I used both Lenovo's and a generic phlash16 executable). I recently had to go through this again and I found it will ONLY work with the non-Lenovo version, which you can find here. As for parameters, as long as your phlash16 is new enough (I found some older version refused to accept /FORCE as a parameter) these should work fine: /MODE=3 /R=3 /S /X /FORCE /Z /EXIT

Note that using the non-Lenovo phlash16 erases your model number, serial number, and UUID... I ran into that last time as well and, of course, I can't remember exactly how I fixed it. I know I used the parameters in phlash16 to set the model and serial, and regenerate the UUID, but that just isn't working for me now so there must be something more to it that I figured out by accident the first time. In any case the UUID/model/serial aren't that important and I'll probably just use it as is.

Thanks. guy your M57 Q35 bios mod is great work on my 6068 type mobo.
-I Flash using usb dos phlash16.exe
here for the proof....my X3363
