SSA-1201-12 is probably limited to 102W because of large current. I don't think it is a typo. I don't know if it is for OEMs only. Actually I emailed SeaSonic asking for availability and they sent me a datasheet and a contact to a local importer in my country. That's probably the way to get it. I ha...

I have picoPSU-160XT (because of high MTBF rating) and a Seasonic SSA-0901-12 brick. This AC-DC brick is a 80W model with efficiency of >= 87% at 25%, 50%, 75% and 100% load. Even at full power the brick is barely warn running at less than 45 degrees Celsius case power. It has no fan. http://pctunin...

Leave CnC enabled and just change P-States. The Windows will do the rest.

There is no reason for BIOS undervolting when you have control of P-States.

Leave everything as is. PhenomMsrTweaker is used to change P-States parameters. Just set new values (new frequency and voltage combinations) and the OS will do the rest. It is very simple.

I have an Athlon II X2 250u (25W TDP dual-core K10 at 1.6 GHz). The chip runs at 1.050V VID at 1.6 GHz and at 0.900V VID at 800 MHz. But it can undervolt to 0.9V / 0.75V if desired. Combined with 4 GB ECC RAM, AMD 760G mini-ATX, picoPSU-160XT and a newest Seasonic AC-DC adapter, I get just 23W at id...

Multiplier is changed by Model Specific Registers access. As far as I know it is easier under Linux to access MSR than on Windows. Details, however, are hidden under NDA (Non-Disclosure Agreement) - I can't give you exact guide how to do that. You may find something in K8 BIOS Developer Guide availa...

KM400A is KT400 like so it is reg. D5, bit 2 must be 1.

Voltage, however, can not be changed as there is no single desktop motherboard with SoftVID pins connected. You would have to make serious hardware changes to motherboard (soldering) to make it work. There was a guide in japanese how to do this.

For bridges meaning, read (the table) http://www.cpuheat.wz.cz/html/AXP_multiplier/AXP_Multiplier.htm AMI BIOS follows notebook guidelines and after start immediately switches to L6 value. AWARD doesn't do this. That link you posted focuses on Stop Grant disconnect. This can not lower your full load...

If the BIOS is AMI, then this is normal behavior as multiplier is set by PowerNow! transition to L6 bridges value. Until you change L6, you will have a max. multiplier, regardless of how you change startup L3 multiplier. If the BIOS is AWARD, you must be one of those unlucky people who got locked ch...

It has some high pitch whine. I think it is comparable to Hitachi 7K250, eg. not the most silent drive but still acceptable if you don't want to sleep directly to it. You don't have any other choice anyway as Samsung is 160GB at most and all other HDDs have some sort of this noise. SATA Seagate 7200...

I have two DiamondMax 10 drives 200GB each in RAID1 (two 100GB platters per drive). It's idle noise is comparable to Hitachi 7K250 / Seagate 7200.7 drives, little high pitch. Samsung P80 (NIDEC) are quieter, at least when they are new. Seek is clearly audiable but if you turn on AAM, it is inaudiabl...

I tried both models and they are not good. The rubber is too tough to stop vibrations hence it only changes sound from medium altitude to rumble because it stops only very strong vibrations, not regular HDD spindle and not short seek vibrations. Zalman 2HC2 is much much better than those. But if you...

Pretaktovanie: - ACB bearings with 137000 hours lifetime at 40 Celsius - Warranty 6 years because bearings don't get noiser in time - 45cm cable - 4.5cm height (= not suitable for PSUs) - only outtake - fan mounted on rubber to stop vibrations - 1900 RPM and very quiet - very quiet, no clicking nois...

http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/30430.pdf Max TDP is 67W for all of them, if this is the same 67W as the 89W for the 130nm parts was (i.e. it has some headroom for future processors) this is very good news! Min P-state at 1000Mhz didn't really improve much (f...

Maybe Intel has tighter tolerances? Considering both CPUs are performance equal (2400+ vs. 2.4 GHz) maybe just in this application P4 can profit from it's architecture to do the same task with lower power. Have you tried other applications, ideally heavily optimized for both platforms? I am thinking...

Excellent! Thanks for the info. Now, my next question: what *is* the deal with multiple DIMMs and CnQ? The CnQ article says "AMD has confirmed that Cool'n'Quiet works with multiple memory sticks." But I downloaded the manual for the MSI K8N Neo Platinum (one of the mobos I'm considering) and it say...

Thanks!

Yes, I mean "measuring". Sorry for any inconvenience.

Projects - I am now working on a PowerNow! utility but it takes much longer than I expected. We are two people who work on this and just do not have enought free time in right time. I hope I finish it in few weeks.

Hi! I will explain how I calculated those power numbers. But first a little explanation of how CPUs work. Modern processors use RISC core. x86 instructions are decoded to OPs and those are send to execution units in a way maximizing overall usage of those units. Athlon CPUs have 3 instruction decode...
