    Speedstep will keep your CPU throttled down (by lowering the multiplier) until such a time as an application demands more juice. Enable Speedstep (EIST) if you're concerned with energy conservation and/or the reduction of wear and tear on your CPU. Glad you got your earlier problem sorted...

    Nope. There are essentially no performance gains. Now, if you wish to enable SATA hot-plugging, you will need to have the drives running in AHCI or RAID. Otherwise, the only other feature you would get in AHCI is NCQ, which appears to offer nothing in the area of performance gains in a single...

    I have an E6600, as well, and I stopped updating the BIOS at 1901. Later BIOSes appear to be geared more toward the quad-cores. In any case, you'll want to check the AI Overclock area to see what your FSB is set to. It should read 266 (stock Core 2 Duo FSB). You can access the AI Overclock...

    I see no reason why the board would not be perfectly compatible with 1333 FSB CPUs. Overclocking a E6x00 to FSB 333 (1333) is essentially the exact same thing as a E6x50 running at FSB 333 stock. -phil

    Asus P5K Deluxe Disaster - really need some help...

    The easiest thing to conclude, here, is that the board is faulty. Ultimately, though, it's too early to jump to any conclusion. This could easily be a memory or PSU issue, or simply a compatibility issue that manifests itself with whatever settings you're using when configuring the BIOS. The...

    You will only get full use of 4 or more gigs of RAM with a 64-bit operating system. 32-bit operating systems have a 4GB memory address limit, some of which will be allocated to hardware devices, like your videocard, PCI bus, etc. This is not BIOS related. -phil

    Seems to me that is a fairly widespread issue, as many people with different brands of memory, are having the very same problems. Have you tried running with SPD timings, with both Hyperpath 3 and DRAM Throttling disabled? Also, make sure the memory remap option is also disabled, when using...

    I recall reading something a while ago that suggested one needs to loosen memory timings when running 4 DIMMS. If everything runs stable with DRAM Write Recovery Time set to 5, I would not necessarily see that as a bad thing. -phil

    Another user recently discovered how to properly convert the Ez-Raid ports into a single non-RAID port. IIRC, you need to completely remove the Ez-Raid jumper. Better you scan back until you find the post in question. -phil

    Option #1 is pretty-much how I have my machine configured. A raptor for OS and apps/games, and two 7200 rpm drives in non-RAID, for storage. RAID1 in a home, single-user environment seems like a waste of a drive, to me. Just periodically backup your data using an imaging application like Acronis...

    Yeah, I just read through your posts, and you seem to be having similar issues as myx. As with myx's situation, it's hard to know what's going on with your system. Unless you can consistently reproduce the problem, it's hard to diagnose with any certainty. Hopefully, both of you will have better...

    Are you running Vista x64, by any chance? I ask because CoreTemp did exactly that when I tried running it under Vista x64. I assume the problem is due to the fact that CoreTemp does not yet have a signed 64-bit driver for Vista, which is a requirement unique Vista x64. In the future, should you...

    For starters, the memory remap option should only be enabled when using a 64 bit OS. As for this board supporting 4GB of memory: whether using 4 x 1GB or 2 x 2GB, it should be just fine. Since, you're only having issues when using slots 2 and 4 together, I don't see how it could be OS...

    I don't know, I'm quite stumped on this one. Just out of curiosity, what are the memory timings set to in the BIOS? Is SPD enabled, or did you disable it and manually set the timings? If it's the latter, try running with SPD timings. Perhaps, you should also try running at stock CPU settings -...

    Glad the rig is running smoothly. If you wish to further overclock, I'm afraid it's all trial an error. You can certainly search around for complete BIOS configs for certain overclocks, but there's no guarantee that they will work. We may both have the same CPU, but each of them will likely...

    Interesting problem. Are you absolutely sure that these problems only occur when running with 4GB? From what you wrote, your problems seem to only occur when doing video or audio intensive activities, while CPU/MEM intensive activities cause no problems. I'm not sure what that suggests, but I...

    P5B Deluxe - how do you enable NCQ on SATA drives?

    Raid requires an array of 2 or more HDDs, and would require wiping all the drives in the array. AHCI is precisely for those that wish to enable all native SATA functionality, without building a RAID array. Anyway, it sounds as if NCQ is automatically enabled when available. -phil

    P5B Deluxe - how do you enable NCQ on SATA drives?

    In order to enable NCQ on your SATA drives, you need to run them in either RAID or AHCI modes. If you already have the Intel Matrix Storage Manager driver installed, you can go ahead and set SATA as AHCI, in the BIOS. Once in windows, open the device manager and right-click on the drive. There...

    CoreTemp 0.94, and now 0.95, have worked perfectly for me, in Vista. You just need to run it as adminstrator. Judging by your core temps, you likely have a bad mating of the heatsink to the CPU heatspreader. If you're not planning anything more than a moderate overclock (20%, or so) you could...
