Are you sure I cant place a xeon X5XXX as the xeon x3363 costs 3x more than an X5XXX, I live in a country where everything is 4x more expensive than in USA >

Hmm, e3323 (771 with adapter) and x3220 (775) don't work on my 755 USFF...
I read, that the BIOS would support these... But i got "Unsupported CPU. System Halted"... what can I do? Have the newest BIOS
...i am requesting a bios microcode based on the LGA 771 mod
Post is for LGA 771 NOT Q based processors for reference Confirmed CPU support by dell other sources. Specifcations regarding Q550s CPU (For Reference)
Bios download links (would prefer Serg008 for mod) the CPU i want support for: (Core 2 Quad Q9550s\SLGAE\06) i would like to add microcode support specifically for USSF\Q35 motherboards What happens? motherboard powers on fine with my Q9550s CPU, however, i can't pass post (System Halted, Unsupported CPU!) i also have many 755 units to attempt flashing, Bricking these units isn't an issue. any other specifications you require, please post reply... *i will post motherboard snapshot tommorow

Your native BIOS already has microcodes for CPUID=1067A, version A0C, date 10/03/2011.
Your revision of motherboard don't support this CPU due hardware limitation - the number of voltage regulator. Error Unsupported CPU and warning Incompatible Processor has different reasons.

I need screenshots of first (CPU), third (Mainboard) and fourth (SPD) tabs of CPU-Z.
I think your motherboard can run any Core 2 Duo, but can't - any Core 2 Quad. Core 2 Duo E8600 is best CPU for your motherboard. User datahog from DELL Community has this sign: Quote:

I still have my X5460 from when I did the Inspiron 545 mod on here.
I have a Dell Optiplex 755 full tower with a q35 chipset, does this support the X5xxx processors? My Dell Precision only supports the X53xx and X51XX processors.. X5460 mod for that too? |
