Did anyone find any Windows application that allows me to mange the multiplier/voltage in similar way like RMClock. I know that RMClock is currently beta testing new release that might finally support Phenoms, but are there any other apps that have been updated to support the Phenom? I'm stuck on AM...

Worst case.

If there is no sub 4x multiplier, downclock the fsb? But not sure what type of performace hit that would be..

New unannounced chipset, AMD 740G http://www.pcper.com/#NewsID-5998 From the look its a 55nm shrink of AMD 690 (80nm). Checked some internet shops in Poland, and area already available. The greatest strength of this platform is likely the power consumption. At idle, with 2GB of memory, a 500 GB HD, ...

Outside of the "fire" look of the IFX cpu cooler. Its lighter by 30grams and now accommodates 80cm fans :) Now we just have to wait for a review (and hope its not as bad as the CPU cooler (IFX-14 that is) Also these coolers look to be already available at polish store www.zenfist.pl Do the guys/gall...

Overall Gigabyte is out as it is simply a tad to big, it uses full 244x244 format. I need something smaller.

I'm just thinking. Should i go for the 90nm 35w version (safe bet it will work) or 65nm 65w version and undervolt it. (but then it totaly depends on the motherboard - or Linux Kernel Mod)

Suffice it to say, this board is high on my list. But as luck, one of the local shops started to carry X2 3800+ EE SFF 35W version :) So that brings lots of options without even undervolting. I'll will double check if any of them carry the X2 3600+ (65nm version) as most seem to have the 90nm EE ver...

Techreport.com had a nice article showing that price/performance the x2 3600 was the clear winner. Watt wise its hard to say, there aren't that many reviews showing that. Generally, AMD690 is decently power efficient compared to equivalent intel platform. CPU wise some sites show about the same, oth...

Interesting concept.

now just PicoPSU mem and heatpipes tho cool the CPU and it will become nice silent invisible project.

Can't wait for more progress.

OK. I tried to investigate the issue of software undervolting in Linux, and in general, though not as easy as windows, there are possibilities. So since there aren't many options, I'll have to just cross my fingers and hope i don't mess anything up. Still in general undervolting via BIOS is more com...

That is just the info that was provided. But it would be interesting if the source site performed this test on other boards to determine what type of VRM is better. Either way, i looked that the Asrock boards, size wise they won't fit. :( Everything else is :) Size being an issue. Again, with regard...

To tell you the truth, the information was posted here on the forums. It showed that the 4 phase power regulator was not as efficient as ASUS 3 phase. A German site performed direct measures of CPU power consumption. And with the two boards above, it ended up that the ASUS was much better. Top end w...

I posted a inquiry in System Advice under Silent Cluster post, but as expected, no one replied :P So generally what i hope you guys/galls can help me with is the selection of the board. I live in Poland so access to all the board manufacturers is difficult, but I hope not impossible. Platform will b...

intresting thought... I might try something out when i get back home. Next Thursday. Current experiment is to run the picopsu from the ATX Power supply 12v line. My system should excede the 120W limit, so i guess i can check with the risk it will "Blow up" :P But the main problem is that once i run ...

It is possible that the efficiency of the power supply has changed. Since removing components does not add but remove load. Remove the hauppage pvr 150 and check the power consumption when its removed. This would permit to exclude or include it as part of the increase of the power. As for the new PS...

OK, i see not much intrest in this project. No worries, that was expected. Generaly i would like to just find a good motherboard. AM2 Requirements. Undervolting. matx under 224 x 220 option to disable everything including onboard vid to reduce power to just CPU/MEM/NIC. edit :: gigabit nic for netbo...

I tried to experiment. For my project, phase one was 75% successfull. I used a regular PSU, from one of the 12V i connected the PicoPSU. The P412v was dirrectly form the PSU. ANd system worked. When i shut down the system, only picoPSU turned off, main system was still a go :) (one step closer to cl...

Ok, thanks. So now i have to find the P412v power addaptor. Wonder if the PCIe would work.. Either way, back on to the subject. Ant6n What happens when you remove the 7600gs, i'm guessing you don't have any older, much older pci card you can test with? as with regards to the P4s you have. what type ...

Intresting results.

But looking at the available data its hard to judge if its a strait line or a curved line.

Is it possible to run more samples?

But i have to say, this approach is quite intresting in checking power consumption of the CPU. Well done.

Thanks for the info. So that covers the Window machine. But my project will involve 4 nodes running on Linux on a matx board (not sure which one yet) and 1 master node, running windows and linux (ubuntu to be precice). Anything equivalent for the linux environment? And again thanks for the info. So ...

I'm going to guess that undervolting sacrifices C&Q? I know that DFI and most other boards had overvolting with C&Q by having voltage adjustmen like Vcc 104% etc. It be nice if there is a board that permits undervolting with C&Q. But from what you are saying, most people easly reach near 1.0V for 36...

Did the standard kit, PSU without the ac-dc brick, come with additional cables like atx 12v 4 pin plug? Or is that extra?

I live in poland, and just recieved 4 nice picopsus, but only they picopsus without any additonal cables. And board won't boot without the additonal atx 12v 4 pin.

The idea of the "psu calculators" is that you can estimate how much power you might need. Were as the wattage meter is for when you allready have the system at home and running. Small difference. I guess when it comes to accuracy. You can estimate, buy and measure and submit the results to the devel...

Got the Seasonic energy+ a month ago, and now this.

Still would be nice to know how much better the S12 II is compared to S12. Can't wait for silentpcreview of it.



Additional website where you can get it is:

now to add more spice to the project, and hopefully some help with dual channel/single channel question. Generaly each node (CPU/MEM/MB) will run of a picopsu connected to a seasonic 550W 80+ 12v rail. :) And cooling will be passive (i hope) for each node. Generaly i want to fit 3 or 4 nodes in one ...

Want to build a small cluster (all fitting in a standard case). My current case is just around 19cm wide. main board will be ... well not sure yet which one. Generaly speeking rendering cluster is my concern, so keep that in mind. Generaly speeking Core2Duo has overall best performace/watt ratio. So...

First of all, impressive comparison. As with regards to the techreport total system power consumption benchmark. They used a nvidia 590SLI chipset wich is.. quite power hungry. ATI would should the AMD cpu in a better light. Even though I'm awlays rooting for the little guy, this time Core2 Duo is q...

Thanks. I am considering the C2D and AM2 system.. Most likely an mATX or smaller board, mainly CPu and memory. Current idea is to run a PicoATX power supply of a main power supply, most likely a Seasonic 650W+. i just have to find more info on how much power do components take to see. Also the new f...

First of all, Yes I did use the search engine. Usualy they don't like me much so I didn't see anything similar. So. What are the issues/problems one might be faced with running two system boards running off single power supply? Currently i have an DFI lanparty with X2 3800+ and 4gb ram Looking into ...

There are a few simple solutions. one power supply manufacturer specified its powersupply as being able to run in pair. How, simple ATX cable that automaticaly turned on second power supply. Not sure if it actualy was able to link the power lines of both ATX lines for single motherboard, but morelik...

I've seen here on SPCR that there was a single reference to 240VAC test on a powersupply, and there was a difference, would be nice if SPCR could do a single test, taking the most efficent powersupply and see how much better it performs on higher voltage.
