W3V Undervolting Advice

Having gone through the very comprehensive tutorial here on the board for undervolting, I'm very pleased with the changes. I have a question about the the creation of additional states using RightMark CPU.

I've created two different states, 0 and 1, with an FID of 6.0 on the low end and 14.0 on the high end with voltages of .700 and 1.004, respectively. I've configured RightMark to automatically manage the processor performance in both AC and DC modes.

My question is, with this configuration, will my processor only run at 1.86 Ghz (14.0 FID) AND 800 Mhz (6.0 FID)? Stated another way, is the processor either floored all the time or throttled back all the way? If so, should I create additional states in the middle (with multipliers of 7, 8, 9, etc.) so that the processor will run at a range of different speeds?

Sorry if this is a stupid question, but I'm brand new to the concept of undervolting. Thanks!

 

Depends on what applications you use. The way you have it configured is the way the default driver is set up when using XPs own system. If you use software that will allmost, but not quite, run adequately at the lower setting, then adding intermediate steps may be beneficial.

Video decoding and playback may be an application, depending on what filters you use and type of content, where such a stituation may occur.

 

I haven't used rightmark, but CHC allows you to set any number of multipliers. I have mine set in intervals of 2 (6x, 8x, 10x, 12x, 14x).

 

Write down the numbers that you have for the max and min voltages then, in the use p-state transition window where you originally set those voltages look for a button on the right that says 'default' Click on that and it will automatically create 9 states for you and audjust them according to the max and min. Now set the '0' state to the low voltage that you had before and the 8' state (max) to the high voltage that you had before, it should automatically adjust the states in between.

 

Awesome- that worked perfectly! Thanks!

Anyone have any input on whether I should use the "on demand clock modulation" on the management tab? How does this differ from the p-state transitions above? Now that I've set up 8 different states, the processor changes its speed according to whatever activity is going on. So what does the "on demand clock modulation" change? Thx for any input!

 

Disable ODCM because it basically does what p-state transitions is doing, just not as efficiently. Also, close power4gear because it will just interfere with RM Clock and clock your cpu down way lower than you want it to. I uninstalled power4gear on my w3v.

 

After you have 'optimized' the volts on your w3v. Could you give me a before and after. Both heatwise but foremost noisewise.

Does the fan turn on during normal windows use(web browsing etc.)?

 

My cpu is around 10 degrees celcius cooler after undervolting. Before undervolting the cpu was around 68 C when just idle or doing like work, now it reaches 68 C only under heavy load. Generally when idle it is in the low 50's and high 40's. The fan is always on no matter what, however, after undervolting the fan is always on low. This is very noticable because if I close RM Clock the fan will go on high after a couple of minutes and when I open RM Clock again it promptly goes back to low.

 

I'm using RightMark CPU V1.6 with only the upper and lower limits defined.

The CPU operates at the various steppings in between the two limits. This can be seen by looking at the Monitoring page in the software which shows how the voltage and frequency change with time.

I have seen a drop in maximum temperature of about 10°C since undervolting. My HDD is the hottest component during normal operation.

I've had similar undervolting results as everyone else here, I'm using a Z63a though. So far I've noticed that the fan never goes above the lowest setting unless I'm at full load. Before the fan would get louder after about 10 or 15 minutes of websurfing or light work. I'm pretty happy with these results.

 

Just wondering what ppl feel is better... CHC or Right mark for undervolting

 

That to me is really strange? I mean laptop hard drives are (generally) cooler then the CPU/GPU. Does anybody know exactly what HDD is in the W3V and Z63a?

Anybody who has tried to change the HDD?

 

I like CHC, but I keep getting the notification that my HD is hot. And its only 55c. I'm sure there's a way to turn it off, but i'm lazy.

 

To clarify: I'm using a Seagate 5400.2 100GB (not the original, which is a Hitachi Travelstar 80GB 4200RPM). The HDD is currently at 52°C and the CPU is at 47°C. The room temperature is 28°C.

The maximum rated operating temperature is most notebook HDDs is 55°C and I find it easy to exceed that temperature if I give the HDD some work to do. I once ran the full Seagate diagnostic software and the temperature reached 61°C.

For reference, the same HDD used to be in a Sony S series and ran about 10°C cooler. It seems to have better ventilation.

There was discussion about the relatively high W3 HDD temperature 2-3 months ago, but it went quiet. The Active SMART software predicted that my HDD would die by the end of May, but it is still running.

I have a Hitachi 7k60 which I put in the z63a myself. So far It's been running in the low 40's according to Motherboard Monitor. I havent seen it get above 50c yet. I have the air conditioning on at a pretty decent level though. I do notice that the panel underneath covering the HD gets really hot, like almost enough to burn. The palmrest stays nice and cool though.

 

I am using CHC and I was wondering if it matters what we set our voltage as when pairing it with our multiplyer. I have mine set 1->14 and i dont know if the voltage has to increase by a specific amount from 1->2 and from 2->3 etc... Does it also matter what speed our cpu is? I have a W3V so my cpu is 1.86ghz.

 

My W3V with the original Hitachi 60GB5 5400 RPM drive typically gets up to 45-50 C during normal use, and if I'm gaming, after a while it will reach 55C. 55C is the highest I've ever seen it get, even after several hours of gaming. (CPU temp sometimes gets just over 70C). I'd be worried that the HD life would be decreased if the temperature goes over 55 often. Has anyone with the Hitachi 60 GB seen a higher temperature? Or does it only get over 55 with a higher capacity HD?

 

Ok, intresting. Is it easy to change the HDD? I guess it would be the same as changing HDD on the W3V?

Did you use the original HDD? Was it hotter or cooler then the 7k60?

 

I actually ordered it without a drive so I don't have any comparison. It's easy to swap out a drive in this unit but a little different than other notebooks I've used. This one has a little IDE ribbon connector thingy that must be proprietary to ASUS or something. Also there is no hard drive "cage" or anything to screw the drive into, you just sit the drive in, connect the ribbon and put the panel back on, only 1 screw needs to be undone for the whole process and that's the one that holds the external panel on. It seems pretty snug though , the inside has a bit of padding.

FYI if you change out your drive It'll probably void your warranty, I wasn't too worried about this since I have the z63a which is "built on ASUS" and doesnt come with the 3 year warranty like the W3V.
