P4 3.06 for Folding?
Does anyone here fold with a P4 3.06Ghz 533Mhz 512K HT? If so, approximately how many PPW does it produce crunching Gromacs?
Just wondering if it is at or near the 1000 PPW that my 3.0C is producing. If so I may replace the one I sold.

Hmm. Checked at MS and there's some mention of HT apparently working on 2000 Server, but no direct mention of HT working on 2000 Pro.Copper wrote:Come to think of it, HT requires Windows XP. I'll be damned before I'll buy another copy. So much for the 3.06.
Intel says, "The following desktop operating systems are not recommended for use with Hyper-Threading Technology: 2000 Pro, blah, blah." Good to go on XP Pro or Home.
Get this, though. On my ASUS P4P800-VM mobo with P4 2.8C, with HT enabled in the bios, running 2000 Pro with SP4, I'm getting frame times of:

If only I had 2000.
I'll stick with the 2.4B for a while, see how it goes. I need to experiment with my Reserator, sitting here waiting to be installed. If I don't lose my disappointment with the 2.4B I'll go with an OCed Barton mobile before I buy another OS. I'll just need to be sure to get a motherboard that has an on-board video that is compatible with Windows ME. I have ME laying around doing nothing. I assume, anyway, that Barton isn't particular about its OS.
Hell, it probably wouldn't be difficult to match or even beat the price of an OS with a Barton and board combined! ($150?)

The reason why Win2000 is not recommended is because it does not know that one of the CPUs is "virtual". Only WinXP and above knows that if you have a HT-enabled CPU then there is 1 "real" CPU and 1 "virtual" CPU and it schedules accordingly. Win2000 thinks there are 2 "real" CPUs and so scheduling might get screwy. I'm not sure what the real life consequences would be of that, particularly for folding. However, people that don't choose WinXP over any predecessor MS-OS need to have their gray cells checked. WinXP is absolutely the best desktop OS on the market if you compare it to anything MS has produced.
Re: Don't use W2K and HT.
Ok, I'll agree that there's no reason to buy w2k instead of xp. Since I already have w2k, ht seems to work satisfactorily on it and folding is the only thing that the box does, I can't get excited at all about buying another copy of xp.
W2k has, umm, other advantages, also.

Motherboard is an Intel D845GVSR micro atx. Power Supply is a Coolmax FL-350ATX(CF-350). The Collmax is one of the new fanless models.
Another small contributer over the 3.0C system is the hard drive. At least I think it is? The 3.0C uses a notebook drive and the 3.06 is using a 7200.7. If I remember correctly it pulls over 10 watts, 12 or 14 maybe. I have another notebook drive ready to go into the system but I'm still waiting for the 44 pin to 40 pin adaptor.

I'm curious as I'm thinking about getting 1 or 2 "more efficient" psu's. Rite now I'm looking at the Zalman 300a or b.
I've got 3 7200.7 pata drives and I'm going to try and see what the current draw is whilst running - on one anyway. It would seem that a running drive, with no activity, would draw little current. Just using common sense, here, I've got no evidence to back this up. Yet.

Yeah, I was just looking at the SS-300FB. Problem is, they don't seem to be widely distributed as I only found them at a few places, like Silicon Acoustics and Essential in NY.dasman wrote:I'm really happy with my Seasonic -- I got it from Mike C (he had some pre fan rev versions). If the new A3 is as good, that might be the way to go.
Compared to my Antec, draw at the plug went down about 30-40w (IIRC from around 220 to 180) measured with a WattsUp? (think killawatt).

I'm gonna contact Mike and see what the scoop is - thanks for the reminder.

A word of warning, HT on Windows XP is a blessing.mas92264 wrote:Hmm.

HT on a W2K system is a ... questionable affair. Windows 2000 doesn't know about HT - it interprets the 2nd (logical) CPU as a seperate CPU, therefor thinks you actually have a DP-system - which you do not.
Win2K is considerably less good for the benefits of HT. XP "always on", but in Windows 2000 ... try it out ... YMMV depending on the app.
Not folding related, but I happen to know a few things about HT - and Windows 2000 is a very iffy subject on the matter.

So far, this setup has produced 89 + 96 wus, machine id 1 and 2. I've used 3 different processors (2.4A, 2.8E and 2.8C) and 2 different motherboards (both #865 chipset) all running on the same hd, a Hitachi 160g sata. It has never aborted a wu.
I know it's not supposed to work right, but it does. Perhaps this application, along with the computer really doing nothing but folding (I have another box with a 2.8C and XP that is my main computer at home) just doesn't create any problems with HT.

The 3.06 undervolted Prime95 stable for 24 hours @ 1.35 Vcore in the Zen. Total watts, without monitor, folding the same work units as the 3.0C is 84, down 6 watts from the 3.0C and down 24 watts from the 3.06 at default Vcore. Moreover it's down a whopping 72 watts from the 3.06 in the other system. Same points, 72 watts less.
Seems my problem is a combination of not being able to undervolt the other board and either the power supply or motherboard, or both. I have a second power supply to try, but its a cheapy with a fan. I'll see how it does.

Actually, it's kind of a funny story. I bot the 2.8E "refurbished" from newegg for $155 with the Intel hsf. I was getting folding temps of about 65 to 70C and the folding performance was pretty much the same as my 2.8C which was running about 10 to 15C cooler. So, I found a 2.6C "refurbished" at newegg for $144, iirc, and I ordered it and returned the 2.8E.
What I got was a 2.8C in the retail plastic bilster pack, never opened, but no retail paper box. Weird. Anyway, I was tickled pink.
IMO, a 2.8E would be fine in an office setting or file/app server, but, it's just way too hot running for a home/trying to be quiet system. I still have the 2.4A, folding away, and will likely replace it soon.
