To have access to more than 3GB in Windows, please do some research on the /3gb and /pae flags for boot.ini. Windows 32-bit (depending on version) can handle up to something like 64GB.

There are a couple settings in the Linux kernel configuration that control memory access. "High Memory Support" and "Memory Model". High memory support can be "off", "4GB", or "64GB".

Didn't know about /PAE, I'll have to try that, thanks.

there is a great tool called BoincView that I use to moniter my comps on a lan not sure how or if it workes over the net Im sure others can help you on that.

Yes, it works well over the net, and you can run it over ssh tunnels too...
It is a fantastic tool to have.

Andy.

My main machine(AMD Opty 165 (overclocked) with 3G ram(stupid windows not liking the 4...)).

Umm... this isn't simply a "stupid windows" thing. It's a 32bit thing. Windows will only recognize whatever the system tells, and most of the last GB is reserved for hardware resources (a large portion of which is the AGP address space, if I'm not mistaken). 64bit Windows (or any other 64bit OS) doesn't have this problem.

My, 32Bit linux machine(not on Seti as it's needed for other uses) will recognize all 4G, but the 32Bit XP doesn't. I know windows reserves it for hardware resources, still don't like seeing 3G of RAM, install 4th stick and still see 3G of RAM...

Does your Linux machine actually allow you to allocate all 4GB or does it tell you that some of it is allocated to hardware resources? Because this is/should all be handled by the BIOS more than the OS.

I know it varies depending on BIOS settings, for instance I have 4GB of RAM on my system that XP would only recognize 2.GB, but when I fiddled in the BIOS, it recognized up to 3.5GB. I can't imagine this is strictly a Windows thing otherwise changing the BIOS should have no effect if Windows only works with 3GB.

By a series of fortunate coincidences I have been able to update the other 2 machines to SSE2. May not show right away as both machines are presently off line. Also got 2 more machines in my sights. I think it may be some time before I can install onto them but the more the merrier. :-( (It's a long story).

Now yet another question. Is there any way for me to tell if the other machines are running or online?

Thanks for the help you have spotted the things I missed. :-)

Thanks to all for the feedback. I will do my best to attend to these things over the next week or so.

I have the SSE2 app on my machine but the other 2 are running the MMX app because they were just setup with a clone of the old machine which didn't have SSE.

Yep, dual core 4200+, 2GB RAM @ 800MHz DDR.
My machine is named Graeme-1.

Oh yes irrelevant but nice, a 22" wide screen monitor. :-P

Going to the SSE2 app should speed you up a little bit more. My main machine(AMD Opty 165 (overclocked) with 3G ram(stupid windows not liking the 4...)) generally averages between 2 and 3 hours for WUs.

Also irrelevent but nice, A 20.1" Wide screen on the linux box next to me and two 22" wide screens plus a 20.1" wide screen on this windows box. :-P

So you should really use CPU-Z or something similar to find out what your CPU really supports.

Since you modestly didn’t mention it, I’ll point out that there’s a nice auto-install package available from the lunatics.at site that will test the CPU specifically for compatibility with each of the optimized apps before installing the most appropriate one. I’ve only used it a couple of times, but it seemed to work fine; one of those installations was on an AMD-based system.

Um,

no, please don't try the SSE3 app on the Sempron. It's an AMD chip and will only run the SSE2-generic application even if it supports SSE3 because of the compiler used (it's by Intel, go figure).

However, AFAIK there are Semprons that support only SSE (no SSE2, even), the first models marked with that name which were really Athlon XPs with less cache.

So you should really use CPU-Z or something similar to find out what your CPU really supports.

HTH,
Simon.

After a very long time I have upgraded to a better computer, the old one was a Duron 950 :-P

Also, running on two other machines. They are not on 24/7 like this one but they are owned by females who spend many, many hours a day in chat rooms and doing PM.

Now what I am after is informed opinion as to whether this is a serious crunching setup.

I don't expect to get into the top 100 or anything like that but I don't know a lot about CPUs etc.

All I can really say is that what used to take 1 hour 20 minutes to crunch a Primegrid WU now takes 13 minutes and what use to take 24 hours for a seti WU now takes about 3.

So those of you in the know want to give me some feedback ?

If I looked at the right machine ( the semperon )I think you are useing the wrong optomised App looks like you are using the MMX version you should get better results with sse3.

If the results output is correct, it does show SSE3 in the specs for that processor. I would run cpu-z to verify, and if so, the app could be upgraded.

Well, looking at the machines you have under your profile, I see 2 AMD X2 4200's and a sempron machine.. If these machines were on 24/7 say crunching strictly seti, you would see a rac of around 2000 - 2200 a day. Not to shabby I say. Like I said above, if these machines were running 24/7 strictly seti.

Bax, yes, he is using chicken's apps..

3 hours is respectable. What CPU are you using and how much ram? Are you using an optimised client?

To provide a comparison, I am running a Core 2 Duo (overclocked) with 3 gigs of ram and I process one WU/hour.
