Well, that's not exactly how hyperthreading works -- you won't get 6.4 GHz out of it, more like it'll seem like it's maybe 3.75 or 4 GHz. And raw processing apps like SETI won't get much speed improvement, and possibly even a decrease. Think of a classic dual CPU machine... If you run a single threaded program on it, you won't see much increase over a single processor. Sure, a bit, depending on what else is going on, but each thread can still only run on ONE PROCESSOR at a time... so a single thread won't be able to use 100% of both procs. It'll max out one of them, and then most of the other stuff Windows does on a regular basis will run on the other.

Consequently, a processor can only run one thread at a time... The active thread is constantly rotated by Windows itself. So when a thread blocks, it might waste the rest of the time in it's slice before Windows can move another thread in there. Hyperthreading simulates two CPU's, so two threads can be running at once - one on each virtual processor. This can eliminate the appearance of wasted time in the system, because Windows doesn't need to worry about that blocked thread as much - the other important stuff just runs in the other 'processor'.

Note, though, that this doesn't make more real CPU time available - you've still only got 3.2 GHz. Granted, there's all funky pipelining and optimzations going on, so you're usually executing more than one instruction per clock, but it's still ultimately just one processor totalling out at 3.2 GHz.

It's *possible* that the hyperthreading is actually lowering the benchmark, then - especially if BOINC is saying, "Oh, there's two processors, I should run two benchmark threads simultaneously" -- because if it DOES run two threads, they're still only going to be executing in that physical 3.2 GHz, and both be innaccurate, and then adding them together would still produce a skewed result. I don't have any idea what's happening for real, though, I don't have an HT proc I can try it on and my only other multiprocessor machine is a P2-300 who currently wants a new hard drive, so can't test it to see.

But my explanation *sounds* reasonable, eh :P

That's a really slow P4 3.2.

I'm getting 2:55 - 2:59 for 2 WUs.

Legacy, I thought the other 3.2 HT looked average. I also have
Corsair XMS 3200 or TWIN1024-3200XLPL. What are you doing to get these benchmarks?

P.S. Average time for a work unit is 3hrs. 28min. or so runnning two at a time.

I find the intel/amd debate really interesting...

I've moved to amd - looks like your average user of generic boxes should too...

I adore my 64...

Ignore the low RAC, haven't been able to keep the box (my main box) fed all the time during all the project ups and downs.

Setup:
Pentium 4 3.0E Prescott @ 230x15 3450MHz
Corsair TwinX3200XL 2-2-2-5 @ DDR460 2-3-3-6 2.85v
Asus P4C800 Deluxe Rev 2.0 BIOS 1016
That's about the highest speed I can get out of my CPU right now, it's rather warm in Singapore about air temp is 34c or 94f in the day and the CPU get up to 63c or 145f. Maybe a vapour chill would really get this thing going. Are you guys using Prescotts or Northwoods? My other box is a Northwood 3.0 and it does about 3:15 - 3:20 for the long WUs.

Northwood.

Asus P4C800E Deluxe here to.

I tried overclocking but my sound card drivers kept randomly crashing it. At least as far as I can tell. Either that or it is the the Asus Probe. Or it was both of them are ganging up on me.

At stock speeds the processor stays about 48c while running SETI.

Actually I suspect the problem is that the user dosn't know how to configure the BIOS;) When your in the bios (on the Asus boards I believe its under "Advanced Chipset") look for the PCI lock and lock it at PCI 33/AGP 66. That should solve any issues you have with devices using PCI and or AGP, when Over Clocking.

Also if its running 48c at stock speeds, you might want to look for a better heatsink before you start OC'ing. I try to keep mine under 50c under full load, and things tend to heat-up a bit when you start turning up the juice.

You have to really play around with the BIOS to find your "sweet spot". Try increasing your V-Core, mine is running at 1.5v, default is 1.4v (warning, increasing v-core is going to generate ALOT of heat, so make sure you have enough cooling and a very powerful PSU and DO NOT go above 1.6v). Increase your V-core slowly and monitor the performance, you will notice a slight increase in performance everytime you give it abit more juice like from 1.4 to 1.415 and then to 1.425, increase the v-core until you stop getting performance increase. Next up ram, low latency is very important. At the moment the fastest low latency ram you can get is Corsair TwinX XMS3200XL, they will run upto DDR433 at 2-2-2-5 and DDR466 at 2-3-3-6. Default voltage is 2.75v but I find my sweet spot is at 2.85v, which is max for my P4C800 Deluxe Rev 2.0. I could do a v-dimm mod but I don't wish to void the warantee. Squeezing that last bit of performance from your box requires alot of patience. Try it out and see how it goes.

Thanks Underground Tech and Legacy,

You were right, I found the PCI lock and set it to PCI 33/AGP 66.

The spec's on my CPU say it should be down aroound 1.4v. The lowest I can set my motherboard is 1.55. I'm not sure why. It is P4C800-E. The revision is 1.xx? The BIOS is 1017.004.

If the lowest you can go is 1.55v then you have a Northwood (P4 3.2C 512kb cache 0.13nm) CPU. The default for your CPU is 1.55v. Only Prescotts (P4 3.2E 1MB cache 0.09nm) CPU have a default voltage of 1.4v.

No problem;)
