Great you have it running somewhat now @Leemarvin - can't believe that about the X vs E CPU!


You'll have to order one of those cheap 30g tubes of paste for $3-5 on ebay, I use those all the time for testing, swapping in/out CPU's, works fine and lasts LONG time!


Yes the mod BIOS you were trying previously did not even had the microcode at all for your CPU, I added latest for all.
I don't remember, your CPU needed 1067A or 10676, and the BIOS you showed me only had the other one which wasn't your CPU, so that's why it wasn't working at all with that BIOS.

Hi everybody, I have an Asus desktop V3-P5G31 with an Asus P5KPL-VM as motherboard. Now the cpu is an intel E5200 and I would like to install an intel xeon L5420. I’ve installed the latest 0610 BIOS version.

So, first of all, is it possible to install an L5420 ? Which steppings will be supported ? Could anyone help me updating the BIOS microcodes ? You can find the original BIOS HERE.

Also I’ve noticed that I can’t flash the original BIOS of Asus P5KPL-VM but I can only flash the original BIOS of Asus V3-P5G31 even if we are talking about the same motherboard but the first one is the piece standalone and the second one is a desktop (with that motherboard). Is it normal ?

Thanks in advance

The l5420 has been tested on the ASUS P5KPL-VM mobo and worked. Both steppings should work,I'd use the EO as it's newer. Asus may have a different code on the pc bios then the Mobo bios which would cause it to only flash the pc bios using the bios flash software.(preventing flashing wrong bios).
Here's the bios you linked to with the microcodes for the xeon's added and the 45 & 65nm socket 775 codes updated.

Ok, I've flashed successfully the modded BIOS. Now I will buy the L5420 and have to wait for some weeks to receive it. I will let you know the result. Big thanks schuck6566

Just out of curiosity here, my main rig is currently in my signature. I've done this mod before successfully on old Gigabyte boards (965p, P35 and P45). My CPU in my sig rig isn't fully up to date yet, that's the planned upgrade path.

My question to you guys, is this Q45 HP DC 7900 Slim Tower motherboard going to work with say a BSEL 400FSB modded, vmodded (slightly overvolt to allow 4.0GHz), Intel Xeon X5470? I happen to have one laying around, but I'd have to order the sticker, and I have no idea if this BIOS will even work with it. The Gigabyte boards were stupid easy, cut the socket, put the sticker on, good to go. But this HP, I have no idea how to even save it without a floppy.

But how cool would it be to have a 4GHz C2Q, 8GB RAM, and 750Ti for a "retro rig" for Windows XP and Linux? I could play every game possible for XP old and new! And Linux, I could play more modern titles (that I can get to work).

The Q & X series chipsets tended to have issues with the 5xxx series xeon cpu's. For more on that & a possible reason why, see here--> https://www.delidded.com/lga-771-to-775-adapter/2/

I have a big doubt about one of the Xeon L5420 that I bought. On one of my pc I notice that this CPU when stressed with tools like Intel Burn Test, the temperature reach 66° celsius degree (idle 35° C). For most of the other processor with TjMax 85° C or 100° C, this temperature under load it's quite normal but with the L5420 with a TjMax of 70 celsius degree it's near the max supported temperature, so I'm very worried about that. I've used the Noctua Nt-H1 as thermal paste in combination with an intel stock heatsink. I've attach a photo with the recorded temperature. Did other users have the same problem with this CPU ? What can I do ? Thanks

When U say U used 'an intel stock heat sink" can U be a little more precise? There are several different ones for the socket 775's. They had the plain aluminum body,short aluminum body with copper core,larger aluminum body with copper core,all of these had different cooling abilities. U may also want to make sure U R getting enough fresh air flowing through the case. As a trial, try running the test with the case open laying so that the heat rises out of it. Finally I'll say that intel burn test is an INTENSIVE test. See if it does the same running Prime95 for example. Prime is also intensive,but not quite as extreme as intel burn IMHO. Images below show the common intel coolers.A lot of people either use 3rd party coolers,or some are using the 1's from the servers.

The intel stock heatsink and fan with the biggest copper cores were the Pentium 4 XE series followed by the Pentium D XE series. I had a few D 840 XE's and the copper core was massive!

Hi, the heatsink model is Intel E33681-001 F09A-12B9S2 02AC2H3 (CX) and has a completely aluminium body. It's the small version. I think that the airflow it's quite decent since there is an 80mm fan on the rear but anyway I restarted the Intel Burn Test with open case and the result it's quite the same. In your opinion, which original Intel cooler is the best for 775 socket ? I'm just wondering how intel thinks to keep the temperature so far from the 70° C when it's under heavy load with an air cooler...
