[MOD] LGA775 Support For LGA771 Xeon CPUs - Page 267

post #2661 of 12378
i used this motherboard with Q9450 and worked well.
I had the same problem with fan but you can go on bios in Hardware monitor set CPU Q-FAN Control Enabel and Chassis Q-FAN Enable, put both of them on standard.
My problem is that if i Load Bios default it doesn't start. I don't want to overclock it just to start evry time, but it start for back-up bios.
I tried set bios default settings after that i made youre sertiings and doesn't works. Do ypu have anything else changed? i have DDR3 1600 but i can't make it see it on 1600HHZ just on 1333.

Somebode posted a BIOS for a EP45T-USB3P with xeon microcodes too here some pages back.

@dvdbackuper
So you don't plan to overclock that Xeon on your board? Although I don't know if and how good of an overclocker that G45 chipset / ASUS board is anyway.
All the Xeon E/X54x2 CPUs have a FSB of 400MHz already and kind of a low multi so overclocking these to much higher GHz will only be possible on very good boards (that hit 500+MHz FSB).

Anyway with the latest official BIOS the board should boot up with an Xeon 54xx but it may not have all the features like SSE 4.1, VT-x and full EIST support.

I inserted the latest microcodes to the 2102 BIOS here:
P5Q-VM-2101-Xeon5400.zip 661k .zip file

Use at your own risk

EP45T-USB3P. Oh, ok, thank you very much for that info. I wonder if adding sse 4.1 will boost some of the benchmark scores.

ofc I have Q-fan enabled smile.gif

There was someone having similar troubles with EVGA 790 SLI . His didn't post at all with Xeon installed until he reflashed bios again.
Try my Bios, maybe reflashing will help. It is latest bios from Asus website and I have modified it myself.

For flashing I used Asus Update V71802 under Windows (don't turn it off it loads slowly, like 30 sec per operation, but it got the job done)

Try it, it should work.

@JohnnyN
Strange. So I guess you have to trial and error with some BIOS settings.

Here we go, found it. Thank you bucho.

edit: Not getting SSE 4.1 or VTX in cpuz after updating the bios. Ok, I see what the problem is. Bios does not have latest codes for Xeons.

Thank you, i tried to downgrade it, upgrade it, i even put an update fot 2008 and the same. I'll try your bios and i hope it's ok. I'll try a 5450 too, i want to see if it's a problem with FSB1600 or maybe i have bend a pin for the soket when i cut the plastic protection. I'll se tomorow after work. Thank you.

Did this mod a couple weeks ago, everything has went well besides a few things.

- Bought a Xeon X5460 off of Ebay along with the adapter.
- Installed it onto an older Dell Studio 540 board to replace the Q6600 it came with stock.
- Booted computer, had to reseat the adapter once due to it not posting.
- Everything seemed to be working fine, except for one thing.
- X5460 shows up as a E5450 in CPU-Z, also only does 3ghz instead of the 3.16ghz it should be doing.
- Image related


- BIOS shows CPU as X5460@3.16ghz but every OS has it clocked at 3ghz.
- Tried some different stuff to get it to run at the full speed, but to no avail.

- It would really be of great help if somebody figured this out, I'll continue to see what I can do.

Your motherboard seems can't handle the 0.5x multiplier, on the picture shown only 9x, the processor has got 9.5x333Mhz=3.16Ghz

Sorry I wasn't referring to my post, somebody else posted a working BIOS for the EP45T-USB3. Should be somewhere between my post with the BIOS and now.
Somehow I don't get the search function on this forum working ... when I try to search for EP45T-USB3 in this thread I get every post as results.

And yes I think you will benefit from SSE 4.1 if it is detected. That is only if the application supports and makes good use of that extension. As far as I know a lot of regular programs and games are programmed and compiled using a generic feature set so that the program works on most processors. Sometimes a specific x86 extension is required for a program to run, that's when the minimum requirements say something like "needs at least a Pentium 3 to run". Just like when a game needs a (for example) DirectX 10 compatible card to run.
How much of an improvement that SSE 4.1 is heavily depends on how much these features are used (and if they are used at all). In case of SSE 4.1 what I've read is just a minor 3D graphics improvement.

So bottom line - I would want that feature set to be enabled and used if deteced.

@KingSnake377
Yes I think dvdbackuper is right, your mainboard doesn't seem to support or use the 0.5 multiplier, at least for your Xeon CPU. I think that's a BIOS issue since I saw some really old mainboard (ASUS P5B with P965 chipset) even got support for that half multi in their latest BIOS versions. The first CPUs with that half multi were the Core2 E7xxx and Pentium (Core based) E5xxx models. So maybe these CPUs also run with reduced MHz or maybe it's just not recognized for the Xeon on your board.

What motherboard? You might have to manually set the 0.5.
