K8N-LR
Does anyone know how to unlock the CPU setting in the BIOS? In the
Advanced CPU configuration everything is there but nothing is highlited. You can not adjust. The only two things adjustable from that menu are GART error Reporting and MTRR Mapping. I have the latest BIOS from Asus. I tried the CD that came with the board opened the utilities and there is nothing for CPU. I tried the SouthBridge and NorthBridge setting also. I have Googled this subject many times but nobody seems to be using the K8N-LR. Is this Asus board non clockable? Thanks for any input. |

Server boards are intended for "reliable" computing, not for overclocking. http://www.asus.com.tw/products2.aspx?l1=9&l2=-1 If you wish to overclock, try Clockgen from cpuid.com . For at least some Nvidia chipsets, the program knows how to adjust the necessary clocks. http://www.cpuid.com/clockgen.php While testing with Clockgen, you should use a separate boot disk that you can afford to lose or corrupt. For example, make a copy of your boot disk, onto a separate hard drive. Only have that hard drive connected. The purpose of this, is to avoid corrupting and losing the real boot drive. Sometimes the boot disk is corrupted, by the overclocking experiments. Paul |

I used that program to up the PCI & the PCIE. I clocked the 64bit slot to 130mz but I never tried anything with the CPU yet. Glad to know about the boot drive and other drives connected. I didn't know that. Thanks for the info. BMAN. |

There are several possible corruption mechanisms to worry about as an overclocker. 1) Corrupted registry caused by bad RAM. If the RAM is not error free, the registry contents can be corrupted when they are written back to disk. Also, if installing Windows, corrupted files can be installed, since they are held in RAM for a short time. 2) IDE cable clock can be derived from the PCI clock. Above about 37.5MHz there can be trouble. Not all IDE cables get their clock that way, but some do. Data transfer over PCI can also be corrupted, if the clock is too high. 3) SATA disks can also have corrupted communications, if the 100MHz clock used as a source to synthesize the cable data flow is overclocked. I've heard of SATA drives being corrupted by overclocking. On some Southbridges that have multiple SATA ports, some ports are more prone to trouble than others. These things are determine empirically by overclockers. As for the BIOS design, there is a pattern to it that follows market segment. 1) Full sized ATX boards generally have the most flexible settings. If you want to overclock, a 12" x 9.6" board is most likely to do what you want. 2) MicroATX (9.6" x 9.6") boards are considered to be for the business market (commodity desktops for business use). The BIOS designers don't consider overclocking to be a priority. In fact, in the past, only a few boards had the ability to adjust memory timings. 3) Server boards are similar to MicroATX, and are very conservative. Some boards even lack options to adjust Vdimm, or use a decent value of Vdimm. There are plenty of people who have overclocked server boards (like the people over on the 2cpu.com forum), but the methods used are not always easy. If Clockgen won't work, you can always use a "wire mod" and change the BSEL pins. Paul |

I saw the overclocking menu for the pci slots in there also. I don't have anything IDE or SATA I run 3 drives all are scsi with a 29360 adaptec card. Never had any problems with them. The memory you mention does bother me because I don't have overclocking memory. I clocked my Opteron to 2.4 and it's fine but I use PC3200. I think I will get some PC3500 before I try any more clocking. Thanks Paul for the information. BMAN. |
