Re: HT or no-HT Northwood Pentium 4?

Thanks washu. :) The strange thing remains though why the CnQ A64 never gets cooled down to room temperature on long idle runs if it is HLTed by newer OS (and indeed quite a few sources say HLT is embedded in them). An A64 is still using (and wasting) a lot of power even when CnQ and HLT are in use...

Re: HT or no-HT Northwood Pentium 4?

There's one more thing I was wondering. Is there any software-cooling (power saving) for HT-enabled Northwoods, or something alike? As I said before, Windows already does this automatically. It executes the HLT instruction when the CPU is idle. As long as you are not running Win98 or older you are ...

Re: HT or no-HT Northwood Pentium 4?

To answer your basic question, HT or no HT: you would have to test. A modern version of Flash will attempt to use HT (as it appears to be a 2nd core) but it may not actually benefit. Old HT on P4s is much less efficient than on modern CPUs. Running the "wrong" code on the HT core can slow down the m...

Re: Can I put an idle CnQ AMD CPU into HLT state as older on

@gamebox: Yes, XP 32 bit executes HLT automatically. Win2K and ME do as well. The behavior you see is because the KT133 chipset is buggy and doesn't allow HLT to work properly without a workaround, which VCool does. If you had the same CPUs on a better chipset you would not need VCool. You don't nee...

Re: Can I put an idle CnQ AMD CPU into HLT state as older on

Why would an Athlon 64 based system be a "power hog" as you reffer? The CPU idle consumption is about 29W, the GPU consumes 7.7W idle/9.9W decoding HD, A modern Haswell or Baytrail CPU can potentially idle at under 1W and that includes the GPU. Even when running full bore, all but highest end or ov...

Re: Can I put an idle CnQ AMD CPU into HLT state as older on

Unless you are running Win98 or older, utilities like CPUIdle are useless. All modern OSes execute HLT automatically when appropriate.

Re: I have a lot of problems with my monitor. Need suggestio

Sounds like the monitor's power supply is going. Probably bad caps. Usually it is the backlight capacitors that go, but the finicky powering on points to the main PS.

If you are good with soldering then it is fixable, but otherwise it is new monitor time.

There is the GRYPHON Z97, but it's expensive. Might be worth it to save the cost of a GPU.

For less money there are B85 and Q87 based boards with displayport: B85M-E/CSM & Q87M-E/CSM

Re: Using old Asus ATX mobo LGA775 for NAS?

Any RAID card that is cheaper or even close to a new Baytrail MB (~$100) is not worth it. Software RAID will be better. RAID 0 or 1 has almost no CPU impact and RAID 5 or 6 is still very low on any even remotely modern CPU. As always, RAID is not a backup. If you can only afford 2 drives then use on...

While your MB "supports" this CPU, the E8400's 1333MHz FSB is *VERY* out of spec for the 945. Not a good idea.

Re: 2.87gb RAM usable out of 4gb? help please.

The 945 chipset cannot remap memory above 4GB so any memory addresses taken up by your video card and other devices is simply lost. Doesn't matter if the OS is 64 bit or not.

If you are sticking with the core 2 generation, get a MB with a G45 chipset and the GMA X4500HD. That is the only Intel desktop chipset for core 2 that has full video decode acceleration for h264.
