    Default new R0 stepping for Pentium Dual Core E5200? BIOS support not far away?

    I picked up an E5200 and GA-EG41M-S2H, and had checked the compatiblity list before purchasing. However, the CPU I received was a newer stepping E5200 (R0) instead of the current (M0) that's listed on Gigabyte's site of supported processors. I didn't even know there was an (R0) E5200! and it appears Intel are in the process of changing over to this new stepping for certain Pentium D-C CPUs.

    The current F3 bios does seem to detect the CPU and seems to do so correctly. At a guess, is this because the current bios supports other Pentium Dual Core (R0) stepping processors like the E5300?

    If it's not officially listed anywhere, how safe is it to use this CPU with this board? I'm only operating at stock frequencies and won't be OC'ing.

    Thanks

    It should be safe. Your hardware isn't at risk. Data integrity might be, as if the chip has compatability problems with the board, data corruption might result.

    To check your CPU is happy and stable on the board, you could download Prime95 and run a blend test for 12-24 hours. Any errors will show in that amount of time. If it passes without error, I'd consider your PC stable and your data safe.

    Thanks, I think I will do that now.

    Regards.

    Well, it passed 12 hours of prime95. I also found Linpack and LinX (GUI) and ran that for about 12 hours too with no errors in either.

    Also found out that these E5200 (R0) and a new E6300 (blast from the past anyone? first time I've seen Intel recycle a processor name) are apparently not officially released until May 30th/31st... so that might explain why no boards currently have E5200 (R0) stepping support (though I see the E6300 is supported in some betas). However, I'm sure Gigabyte are aware of impending product releases and are probably testing it in the background.

    Hi I'm glad it's working for you because I'm in the same boat. My e5200 came in today with R0 stepping. My motherboard is the EP45-UD3R which doesn't list R0 stepping as supported. Hopefully it'll work too like yours. I'll post back my findings for others in the same boat.

    yeah i think as long as your board recognises R0 CPUs it seems to work OK. It appears to detect alright even though the cpu still isn't listed as supported.

    my guess would be that it was probably included in the current bios, but perhaps they never got around to updating the CPU support list..
