ASUS X58L CPU Upgrade to T9500

[DylRicho]

I was successful in trying a Penryn 45nm-based Celeron 925, which works.

This may mean that any other Penryn-based Core 2 Duo, Celeron DC or Pentium DC will work too.

i have x58L, bios 203, x3100 video and i upgraded my CPU from T1500 to T6400 (core2duo 2GHz)

That's good to hear.

My system is identical. You may be able to use any Penryn up to the T9500, even though I'd suggest a T9300 for the best performance to price ratio.

The 203 BIOS appears to have Penryn microcode to support them. 0676 must be the associated CPUID.

My Celeron 925 worked fine and it has the CPUID 067A, which is also in the BIOS.

Hi guys,

I just thought that I would inform you all that the Core 2 Duo T9300 does indeed work, with much better thermal and processing performance, thanks to the Penryn redesign (I guess, Intel's "tock").

So, anyone looking to upgrade their X58L, please read below for the highest configuration that works!

• Intel Core 2 Duo T9300 'Penryn' (2.50 GHz/6 MB L2/800 MHz FSB/35 W TDP)
  
• 3 GB DDR2-800/PC2-6400 RAM (chipset downclocks it to 667 MHz)
  

Using 4 GB RAM will cause blue screens upon start up. The only thing that hasn't been tried for RAM yet is a single 4-gigabyte module, which is proving to be quite an expensive option, hence why I haven't done it yet.

If I or someone else does, I will update the thread once again.
