[MOD] LGA775 Support For LGA771 Xeon CPUs - Page 127

post #1261 of 12329
So X5460 is working on DFI P45-T2RS with added Microcodes.

And the performance increase is just crazy compared to my old E6550 biggrin.gif

Thanks for all the help thumb.gif

Hi, has anyone tried 1600Mhz Fsb Xeons ( E54x2 and X54x2) on P35 or p45? My P35-dq6 supports QX9770, is this equivalent to X5482?

thanks!

Hi,

I was wondering if somebody can help me.

I've done the socket mod on my ASUS P5Q SE/R and got hold of the adapter for a LGA771 cpu.

Managed to get two e5450 CPU's for £30 ($50), my previous CPU was a Q6600.

I have installed the CPU, and my machine boots and works, I've even managed to overclock it to approx. 3.9Ghz (1.3125v) and it's stable etc..

However I have noticed that I appear to be missing some capability from this new CPU.

I have flashed my motherboard with the latest bios from Asus Rev 1005.

On boot up I get a message that states I need to update bios to unlock full potential of CPU, with a count down and then it boots normally.

However I have noticed that I seem to be unable to run 64-bit VM's any more.

I have checked in my BIOS and VTx is enabled, however when I look at the CPU flags on CPU-z v1.67 I see that it's missing both SSSE4.1 and the VTx extensions, which this CPU should support.



Looks like I have something not quite right with my BIOS.

Does anybody know if a custom BIOS exists or can be created for the ASUS P5Q SE/R that supports the Xeon correctly, and enables VTx?

Thanks,



IpD.

Hi all,

Sorry should have read this full post, have now modded my BIOS with the tools mentioned earlier.

And VTx & SSE4.1 are now back :-)



For those who have an ASUS P5Q SER motherboard and want a Xeon Compatible BIOS you can get it from HERE .

Speed Step, SSE4.1 & VT-x all working as they should :-)

This has to be the cheapest bang for Buck Upgrade I've ever done, feels nipper now that it did with my Q6600 @ 3.2GHz.

Thanks,


IpD.

Finally the stickers have arrived. Now I am stuck on the post screen. L5420 and Gigabyte EP43-DS3L running bios F9e(latest, but its beta). I have seen them work together in this thread, first one I found was bios F7, a lot just say latest bios(genarlly on gigabyte boards) and they work. Now am in a pickle.

IpD.

And now sell the Q6600 for about as much as you paid for the Xeon + sticker tongue.gif

Maybe you need to create yourself a modified bios using the instructions earlier in the thread?

Got it working, Guess the sticker was the problem.

My 790i FTW is really proving itself worthy. I purchased a 3x2gb XMS-3 1600 kit, I've only been using 2 modules until i could find one more matching module for a complete set. I managed to find someone selling a single module of the exact memory. I got a killer deal on it as well($10 shipped after Ebay coupon).

I received the 4th module last night...popped it in expecting a BSOD. Man was I wrong...I then proceeded to linked the memory @ 1700mhz with the FSB with pre-meditated defeat. Anticipating a de-bug post code followed by a long beep i saved to CMOS...voila'...it posted and booted just fine. Once i got into windows i ran a passmark memory test with great results as well (1327).

Now normally with 2 modules I have to relax the timings for 1800mhz. Again, I'm thinking to myself this board has to give up the ghost with 1800mhz...just no way possible lol. I plugged in my normal settings for 1800mhz and away we went. My passmark memory scored jump to 1377 at that speed and my previous passmark cpu score jumped from 6901 to 6952 at 4.5ghz

Now I know this isn't a benchmark thread but for those who really want to make their Xeon shine then the 790i boards are where its at. I will attempt 1900mhz once io get better cooling as right now my highest load temp is 72C which is a bit too warm for me. A corsair H110 will hopefully fix this problem as 4.5ghz for me requires an even 1.4v for stability.

P.S. my current rig with the 750i FTW that is pictured in my avatar will be going away sometime in early february so if anyone is looking for a complete system minus a HDD then keep your eyes peeled for that.

I am sure 790i is very nice, but honestly for the price they are going at you could get a sandy setup already. I honest suggest people to buy a $30 E5440 and recycle their existing board. Any more money spent on 775 would be against the whole point of the mod.
