C90s...RMClock undervolting settings?

I've always been a big fan of RMClock for undervolting....but, it's been a long time...does anyone have any tested voltage settings from low to high, options, selections, etc. that they can post here?

thanks

 

Please be aware that voltage settings for stable functioning will differ among particular CPUs of the same type. So there are no general numbers that'll work, at most some guidelines.

Also, does RMClock support desktop CPUs such as that in the C90? I'm just asking, I don't know...

You might also want to have a look at my Tips and Tricks (signature) under Undervolting.

 

Yeah, but I need starting point....hmmm...google is my friend... I was able to dramatically reduce temps on my Acer notebook, and keep it stable. But, that's why I'm asking C90s users...not sure about the desktop cpu

 

To be honest, I don't think most people would undervolt a desktop processor, so my guess this is totally unchartered territory, unless your one of those silent PC enthusiast. The question though is, can RMclock control the voltage of our C90s?

Realistically though, each processor has individual voltage limitations and you will need to test each setting and slowly test each voltage setting until you get to the lowest possible stable voltage. Of course, you will need either wPrime or Orthos to test.

 

Well, I'll look up the stock voltages at different throttles and see what I can do. Undervolting is a win-win situation. I've just been patiently waiting for a version of RMClock that was Vista Compatible

Anyone else?

 

Well it's definitely a Win-Win situation with undervolting since it can lower temperatures and power consumption. However, with ASUS's gaming mode and OC mode it makes it a little more complicated to do the testing, as you would need to do the voltage tests based on the highest OC speed. This will skew the results a bit, and probably won't be a significant undervolt unless you're willing sacrifice those modes and just use standard mode with the lowest stable undervolt settings.

 

Yes, I'm going to try it in standard mode as I never change it anyway...even gaming.

 

OK...I've set RMClock to throttle using existing power plan at start up, between the lowest req voltages. It recognized the conroe as desktop. The question is, whether I gain anything from it....i.e. lower temps. I use the performance on demand profile all the way around, and enable P state transitions. Anyone else try it? It's a fantastic program actually

EDIT: I turned off RMClock CPU throttling because I was getting some video stuttering, that stopped it. I think I've reduced my GPU temp by 4 degrees (ambient heat?) but I need to prove it further.

 

I've undervolted it to minum and gamed with it to see if it had any effect on gpu overclock. Sadly no.

 

hmmm....I'm got the voltage maxxed at 1.2250...I'm getting about 4 centigrade lower GPU gaming, same level each time....I'll keep testing....my card is the gddr3, a hot card normally.

 

But isn't your temperature the limit of your overclocking, not the voltage?

 

Forerunner....I'm running everything in standard mode, even gaming. I'm not overclocking. I need to figure this one out, on my Acer Ferrari I was able to drastically reduce operating temps, that CPU was a 2 ghz AMD Turion. This one has me a bit confused right now...

 

It seems as though RMClock is controlling the voltage. I have it undervolted slightly, maxxed at 1.2250 volts full speed instead of 1.250 stock. I'm thinking I'm seeing a reduction of operating temps by about 4 degrees centigrade. I wish someone else would do this and confirm. It properly recognized the conroe processor, and flagged it as a desktop processor. Interesting.

 

Yes RMClock is quite good and knows a lot of platforms.

For my Core Duo I have gained as much as 10 degrees lower on full blast by undervolting the CPU.

I don't know how your CPU processor will do, but the effects should be as significant.

Is that voltage correct by the way? It looks like a mobile CPU voltage... are they the same for desktop CPUs? Don't forget to load the defaults on the Management page of RMClock before editing voltages.

Can you go lower than 1.225? Is it stable in Orthos as it is now?

 

Yes, the 1.250 was shown by RM Clock as a default voltage at full blast....I'm going to try to lower the voltage a step at a time and see what happens My goal is to lower CPU temps, thereby lowering ambient temps in the notebook case which I'm trying to see will or will not affect GPU temps. Gaming I maxxed at 89 degrees for GPU without RMC, and with it 87. the CPU seemed to drop about 4 degrees. I'll see where it goes. With my Acer Ferrari which ran VERY hot gaming, RMC had a dramatic effect at lowering the temps, something like 14 degrees!

EDIT: Just lowered a step to 1.2125....will fire up the game and see what I get

 

Interesting, I already had RMclock installed as it controlled my CPU throttling. Anyhow this post has gotten me quite interested in undervolting and lowering my temperatures, I haven't been too successful for my 10x multiplier on my E6700 only lowering to 1.325, however with 6x I was able to hit the lowest voltage of 1.187 and it has significantly dropped my idle temps from 52 to 40! My ambient temperatures are rather cool though and I am using a notebook cooler with my ACE door off(this is how I usually use it unless I need to bring it on the go with me).

 

D3X...did you get your stock voltages from the CPU info screen in RMClock? It's been a while since I've use this and want to make sure I'm reading this right.

EDIT: I'm showing 1.0375 as the lowest possible voltage...how about you?

 

Um no, my selection of the 1.187 is the lowest possible selection for me, which is odd. It didn't come from my CPU info screen, but from the Profile tab.

What's your MAX available voltage btw?

 

Yeah I was wondering that too. My max is 1.35 v and min is 1.187 like d3x.

 

OK...same thing, profile tab options and cpu info....max voltage is 1.250 and min allowed is 1.0375 from the profiles drop down menu's. BTW, I had to turn off throttling as I was getting some video stutter in windows ? So I'm just controlling the voltage.

 

Interesting, so the lowest voltage is relative to the max voltage I presume? It would be nice if I could override the voltage settings....

 

Forerunner....I have the e6600....what's yours?

 

Yes, so I'm just taking down the full blast voltage, and letting RMClock adjust itself in-between at the various multipliers.

 

Yep that's exactly what I did. Though I noticed that on "Performance on Demand" mode it only hits 6x , 8x and 10x multipliers only so in otherwords, I don't think it uses the other multipliers in between even though it's displayed on the Profile tab. So I would only worry about the 8x voltage setting if you're using "Performance on Demand" mode. But since your using MAx performance, I don't think you need to worry about it at all.

 

I'm an e6600 also.

 

I wonder if we have the same motherboard revision? Ken knows. btw, Go GATORS

 

The lowest voltage I can get is 1.187 on my e6600. It just wont go any lower.

 

BTW just to make a point, throttling is a different thing from speedstepping. RMClock supports both, and I have also noticed stuttering with throttling enabled.

But that doesn't mean that you can't benefit from speedstepping, i.e., you don't need to keep your CPU running at max speed all the time, you can still use Perf. on Demand. I have never noticed a lag with that profile.

Assuming of course that by throttling you do not mean speedstepping.

To make sure that voltages are correct for your CPU, click again the Defaults button in the Profiles tab of RMClock.

I also suggest never using more than 3 multipliers with the Perf on Demand profile: the minimum, the maximum, and one intermediate. The CPU will almost always be either idle, or at max, anyway. This reduces headaches with testing (you don't need to spend X hours times 6 multipliers stress-testing, for instance; you just need to spend X hours times 3).

 

Did that (clicked defaults again). I'm using PoD profile. It gives me 6x, 7x, 8x and 9x. I have my 9x set at 1.2250 which is down from 1.2500. The other multipliers adjusted accordingly. My lowest voltage showing at 6x is 1.0375. What would you recommend changing? (EBE)

EDIT: btw, I can't get my GPU to go higher than 87 centigrade gaming at these settings. It used to go into the mid 90's. I'm running standard mode, no overclocking anywhere.

 

Well it seems you do everything right. So the only thing to do is to :

decrease the max multiplier voltage in small steps;
let RMClock interpolate in-between;
test thoroughly with Orthos the stability of each multiplier after every decrease.

And thus identify your lowest stable voltage.
Then, you will have undervolted your CPU.

 

Ok. new findings. I've loaded up both RMClock and CPU-Z and found that the voltage readings from RMClock is incorrect, at least for the E6700.

My physical max voltage is 1.237 taken from CPU-Z. Even at the setting of 1.350 in RMClock. And the lowest voltage is 1.075 even if I set it at 1.187, so it's reading the temperatures incorrectly!

What I then discovered in RMClock is the Advanced CPU Settings at the bottom of the tab there is the "CPU Type selection:" Obviously the E6700 is a "Desktop" processor so it probably will be in this setting defautly, but I checked "Mobile" instead, and this seems to change the voltage setting readings correctly and it doesn't affect or change CPU-Z readings.

This doesn't really improve undervolting, but at least it's more accurate and the numbers actually match up.

So just to let you all know, my lowest voltage at 6x is 1.075, and the lowest voltage at 10x is 1.225(down from 1.237).

 

I'm downloading CPU-Z now

EDIT: CPU-Z matches my RMClock voltages, max and min exactly Low of 1.038, high of 1.2250(my setting maxxed).....maybe we should compare our settings page by page in rmclock...?

 

OK....RMClock does indeed control the voltage, but I can't seem to "net" anything out of undervolting it. I can reduce the CPU temps by about 4 degrees C at 1.1375 volts maxxed (below that it will crash under Orthos stress test), but the GPU rises by that amount it seems! Because the fan isn't coming on as fast? My conclusion is we c90s owners are beating a dead horse undervolting due to the way the c90s is designed, unless someone knows something I don't, in which case I'll try again

 

That seems quite possible.
