SMP or seperate instances...???

[Deadbot1_1973]

I'm currently running 2 instances of the console under Vista on my C2D Lappy. Would I be better off with the SMP client? I'd like for it to be as transparent as possible to me. I know that running the SMP as a service isn't recommended, so how would I set it up if it's better to go that way?

Thanks for any help.

I run mine as a service, but as you know it may not be best for everyone. I haven't had any problems yet though. For duals, 1 instance of SMP client seems to work best. I'm sure the guys that have been doing this longer can give you more detailed advice than me though :)

I run Win SMP on my Vista 2.0 GHz C2D laptop using Affinity Changer for maximum production. 1253 ppd on p2653.

Thanks for the help guys. Up and running as a service. Holy cow for PPD:eek: Holy cow for heat...145f and climbing at 100% usage, had to cut it to 80% now steady at 141f:mad:

Guess it's time to crack open the biznitch and reexamine the heatsink setup:beer:

You have to blow the dust out regularly!

Brand new lappy (well, a display model from Worst...er I mean Best Buy). Should be fairly clean. I need to take it down and apply better TIM and maybe get a cooler pad.

I'm thinking about getting a cooler pad myself.

[Deadbot1_1973]

The stock battery that comes with this one(Vaio ar520e) is pretty crappy. 1 to 1.5 hours run time max. I'm actually considering building a combo battery pack/ cooler pad to sit under the base. I plan on using a gasket like herehttp://www.overclockers.com/articles1519/. still doing research into it. Not sure what type and size batteries to go with yet, and deciding if I want to set up a separate set for the fans or slave off the main set. I keep trying to figure out how to crank a bit more oui of it,but Sony's bios is VERY limited(read OC options nonexistent).

was just checking PPD. I'm getting at least twice the PPD for the same time as running dual instances of the standard console:)

I'm wondering about this as well - having trouble making deadlines and considering switching to two singles but not sure how much of an impact this will have on my production.

For reference I use a shortcut to start FaH and my temps go pretty high too...

JESUS. Yeah I would cool that down, because as you are well aware when the CPU is hot, that also spreads out to the rest of the system in one form or another.

[Deadbot1_1973]

David,I would try one of two things. First I would make sure your cooling solution is up to snuff( AW come...on! Your a mod...of course it is:bday:). Second I would throttle the client to 80%. If you are having trouble making deadlines then option 2 is probably out and you may need to go back to dual instances.

IMHO I don't think SMP vs. dual instances makes that big a difference...100% usage is 100% usage. I don't think my temps went up because of the client switch.I found very dried out and crusty cheap paste and a thermal pad in there. I had noted that my temps dropped about 10F when I throttled the clients before, and have yet to try it since switching and cleaning/reseating the heatsink. I saw a HUGE jump in PPD going to the SMP client. An average of 200 with dual instances, and 800-1000 with SMP.

As an experiment I'm going to throttle my client for a bit.
Currently around 65F ambient.
100% gives a temp of 143.6F on both cores according to PC Wizard 2008.
80% gives a temp of 141.3F (and still uses an actual 85%:confused:)
60% gives a temp olf 140 (and is still using around 70%:confused::confused::confused:)
I changed the value in the config file and stopped/restarted the service after each change. I guess that 4F isn't worth the PPD loss. Kinda wondering about the results of this short test...:confused: Guess I'll have to do more testing next week out on the road.

one final editfor the night...I think I see whats going on. I just tried 10% and the usage is actually 20%. 5% per thread x 4. At any setting above 50% on my C2D i'm getting close to 100% usage, as long as nothing else is using cycles.

[Deadbot1_1973]

overnight set at 40% in the config file. Acual usage as shown by task manage is 17% on 3 theads and between 8-15 on the fourth. Temps are sitting at 132.8F. Looks like with my nice clean, re AS5'd heatsinked lappy I get about a 10F drop from throttling with about a 30 PPD loss as reported by FahMon. I'm gonna open her back up and squeeze her a bit to get the AS5 settled in.

A solution!

When I first started folding on my Mac Mini(T7200 proc) I noticed core temps of 80 C(176 deg. F) and was concerned. I subsequently found information that the Mobile C2D's(eg:Merom) run hot, and can take it, for a maximum of 100 C(212 def. F).

I know this thread is a couple months dead, but I ran across it while searching for some help running SMP and thought i'd throw this in! :beer:

You guys with laptops that are folding and running hot should try undervolting your CPUs. I do it with my T7500 in my lappie, and it has dropped my temps from over 80C running Orthos to about 65C loaded with Orthos. The stock voltage for a C2D T7500 is 1.25v and mine runs perfectly fine at 1.075v. Aside from dropping your heat, it also increases your battery life, although not by a gigantic margin. I use RMclock v2.35 and followed this guide at the notebookreview forums. (http://forum.notebookreview.com/showthread.php?t=235824&highlight=undervolt) That guide is geared for C2D laptops, but RMclock works with AMD CPUs too.
