matja Posted December 17, 2004 Share Posted December 17, 2004 I bought a new system 2 weeks ago and built it from components, ASUS P5AD2 premium mainboard Intel Pentium 4 540 (3.2GHz 800FSB) 2x Corsair 512MB DDR2 XMS2-4300 TwinX (TWIN2X1024A-4300C3) Sapphire ATI x800XT PCI Express 470W Enermax Noisetaker PSU (24pin ATX + 6pin PCI-E connectors) The first time I powered-on the system, I got this : R423 XT 113-A31904-104 BR#7984 A12 DDR3 BIOS Rel 18.104.22.168 Boot block compatible version ver.012 Bad BIOS Checksum. Starting BIOS Recovery... Checking for floppy... Checking for CD-ROM... It then repeatedly kept checking the floppy and CD drives for a BIOS recovery disc. From my external speakers, a voice can be heard from the BIOS saying "system fail due to cpu overclocking", this was the first time I powered-on the system so I havent even had a chance to change the CPU settings. There was no beep from the motherboard to identify an error. The motherboard manual says that you can use the CD which comes with it to re-flash the BIOS in the event of a problem, so I tried that, rebooted, and got the exact same message. I thought this was a motherboard problem, so I returned it to the supplier, and bought a replacement of the same board. Had the exact same problem, replaced that one too, same problem. So I'm on the third board now. I have tried using just one module, swapping them, using the other module, etc, to the same effect. I've tried using them in another board too (i think it was an ASUS 915x-based, with ddr & ddr2 slots) and it didnt even boot or come up with a BIOS screen, no beeps, nothing. Do you think I have bad RAM or some kind of compatibility issue? Link to comment Share on other sites More sharing options...
