[MOD] LGA775 Support For LGA771 Xeon CPUs - Page 274

post #2731 of 12376
Which one?
Cause as I said I thought I updated the gigabyte P35-DS3R with my bios but I updated with one I had found eventually, as it was a mess up in that folder and was mixed up with some same naming files but in different zip.

It has a Dual bios, so anyway, any bios should be fine. If something goes wrong the other takes over.
But it did worked (the first version I uploaded was installed)

After all my OCing i tried to reduce power usage by enabling C1E and EIST again in my bios, but my cpu is not really down clocking when idle. I also tried it with bios voltages at auto, but the same thing. I can see in realtemp that it is reducing the multi from 9 down to 8.3 or so (it varies, but never below 8). My old E6600 would reduce its 9 multi down to 6 during idle/low load.

I also keep having the problem that sometimes in cpu-z i see SSE 4.1 and VT-x, but then i reboot my pc and the instructions are gone in cpu-z. But more often than not i do not see the cpu instructions in cpu-z.

So i am wondering if this all has something to do with my bios. Now i do not know if i have to get a modified bios (never done myself) with cpu microcodes to fix this or not. Because sometimes i do see SSE4.1 and VT-x, so aren't they already in there?
And is this low/no downclocking maybe related to my bios too?

-edit-
I just checked in Everest ultimate and it shows SSE 4.1 and EIST not being supported atm.
C1E is enabled though.

So i guess its something with my bios afterall.

I can confirm compatibility with Asus P5G41T-M/CSM Motherboard, 0901 Bios flashed with the Xeon Microcodes, and paired with a Xeon E5450 CPU.


IT'S AWESOME!!!!biggrin.gif

If xeon microcodes are the following entris (and i think it is true)
cpuid 10676 platform 2
cpuid 10676 platform 6
cpuid 1067A platform 2,6
than
1st version looks o.k. (here xeom microcodes are dated 2008)
2nd version = 1st ver. + microcodes dated 2010 (so it has microcodes doubled)
maybe you messed the files and added microcodes to bios file that you found earlier?

I heard that Dual Bios in Gigabyte's boards sometimes doesn't work how it supposed to.
System only posts from main bios and in case of failure the backup bios is copied to main bios, but sometimes this fails and mobo won't post.
You can be forced to physically detach one leg of main bios chip from mobo to make it work again.
On some boards Gigabyte is using something called virtual dual bios which is even weirder.

what is your motherboard?
EIST should work, except of lowering voltage if voltage is set at a fixed value and not in Auto.
Also in Asus boards if FSB is raised a lot then even if voltage is set to Auto then EIST does not lower it. Only if FSB is raised just a little.

Well, the right Xeon microcodes are dated 2010.
In any bios I have modded I have added 2010 dated microcodes.

Gigabyte has multiple types of bios failsafe. They are supposed to do this, prevent board get bricked in case of bad update. But, yes, I can`t know if it actually works all the times.
Asus has also some types of bios failsafe. Most have bootblock lock, so even if corrupted then you can re-update. My Deluxe (or is it the Premium) has a Dual bios too, as Gigabyte`s.

Been reading about the cpu microcode stuff and checking the bios with HxD hex editor and from what i can tell (with the limited knowledge i just gained) the microcodes are not there. At least i cannot find any 7A 06 01 00 (or 76 06 01 00) in the BIOS.

Now i wanted to try myself to add the codes to the bios, but i get stuck at the 2nd step.
I was following this guide (it is similar to the one below the opening post, but with screenshots):
http://www.overclock.net/t/1431723/mod-lga775-support-for-lga771-xeon-cpus/1400#post_21602046

cbrom195.exe BIOS.BIN /nc_cpucode NCPUCODE.BIN
When i run that it just gets stuck or something. It loads the first line just as in the guide:
cbrom195.exe V1.95 [12/14/07] Phoenix Technologies 2001-2007
and then nothing. I don't know what i am doing wrong.

Nvm, stupid me didn't extract the bios right, got it updated now. Will try to flash it and see if that fixes it.

F12 bios is what im running.

When I updated my gigabyte bios to include 1067a microcodes for L5430 I had to save the original unmodded bios using the @bios tool as a .bin then mod the .bin file and then flash that file. I could not get it to work with the file as downloaded from gigabyte. f1,f2 etc.

See this post http://www.overclock.net/t/1461699/xeon-l5430-vt-x-speedstep-and-ssse-4-1#post_21952334

Thanks for the help.

But after i figured out what i was doing wrong i flashed my own modified bios and it fixed all the problems i had. Feels good to figure it out yourself smile.gif. Got SSE 4.1 and VT-x all the time now and the cpu now properly lowers the multi to 6 when idle/low load.

The file i downloaded from gigabyte's website was motherboard_bios_ga-ep45-dq6_f12.exe
And i was so dumd not to unpack that first. After extracting i got my bios ep45dq6.f12
This f12 bios file could be modified without any problems with CBROM195.exe. So i did not have to save it as a .bin file first.

I did everything this guy did, except for the .bin file part:
