Undervolting Penryn?

[flipfire]

Do I need to test the other lower multipliers (9.0x, 8.0x, 7.0x...) at 0.9250 with Orthos?

Do the same thing you did for 10x-12x. Set the voltage slightly lower than the previous multiplier and test stability with ORTHOS.

Dont worry about If you BSOD, it wont save your settings when you restart it will return back to the previous stable settings. You can always go to safemode where RMclock doesnt load and disable it from there if it wont boot up. RMclocks settings doesnt actually load till windows load so dont you worry

As for SuperFLM im not quite sure how to set it properly for penryns. My (2.2ghz T7500) 6x multiplier is 0.937v @ 1600mhz and my SuperFLM is set at 6x 0.850v @ 600mhz for superlow idle and voltage. What the lowest voltage SuperFLM will go for yours? Mine is set to the lowest which is 0.850v and its rock stable

Keep your idle at 0.950v, theres no reason to change this. Just hope superflm will be able to make it go lower.

Your 12x undervolt is so low that im expecting your other multipliers voltages to be very close from one another.

Since your 12x is unbelievably uber low i suggest putting it up by 1-2 voltages to make sure its 200% stable but if your really confident about it then stick to it.

flipfire, I've attached a screen of RMClock and CPU-Z side by side. How can I tell which voltage is in effect using CPU-Z because I see a Core VID of 1.038 close to the top but I don't have that voltage selected anywhere in my RMClock profile. Just want to make sure the voltages I've selected in RMClock are running.

Thanks again...and I promise, I am running out of questions!

Its a glitch.. you dont have the latest CPu-z thats why its not showing the same thing as rmclock.. Ive read somewhere about a glitch on cpu-z not showing exactly because superflm isnt supported yet

38c idle, awesome.

Edit: If you start getting weird/random BSOD's after you completely done the stability test let me know. Also tell me what you were doing (what programs were open)

[rtrdogs]

Hmm... I didn't have CPU-Z before. I just downloaded CPU-Z 1.44.1 from the CPUID Web site to take that screen. Is there a more current version?

[flipfire]

Your right, my bad you do have the latest version. I read somewhere in the RMclock forum about CPU-z giving inaccurate readings.

Not too sure to be honest, i still think its a glitch. Ill double check mine when i get home. I only remember my CPU-z saying 1200mhz even though im on superflm @ 600mhz, dont remember if the voltages were correct.

Yeah, it's a problem in the newest version of CPU-z.

The last version to display the correct voltages was 1.40.5

It should fix the problem you are having.

Also, for SuperLFM, set the voltages to .850v

op your thread kicks ! now i can really see what my chip can do..

[d94]

currently im down to 1.05v on full fload, 49C full load after 20 min of orthos

d94, glad the thread has been a help to someone else too. It's been fantastic for me!

illmatic8, yes, 1.40.5 did the trick. Got a rep for you. CPU-Z is now showing the right voltage (0.925 using the 6.0x multiplier on SuperLFM). My lowest SuperLFM value available is 0.925.


So here are the final results (for now). I may bump up the voltages a couple of notches like flipfire suggested just to be extra safe but I'll keep it like this for a while to see if there are any problems.

I played some games for a few hours last night. I did some work in Ulead Video Studio 11 and PaintShop. No BSOD or any errors encountered so far. I changed my SuperLFM multiplier from 8.0x to 6.0x so here's a screen of everything:

Ok, so after doing some testing my lowest voltage @ max multi 12x is 1.0125 and @ load my temp = 49C w/fan on med/quiet after about a half hour WOOT..this is about an 11c drop from where it used to be!
and idle id down to 24C
