Screw Turbo Gear! Overclocked my C90S with ClockGen!

:: DISCLAIMER ::

I take no responsibility for anyone using this information at ALL!! I do not guarantee ANYTHING!! Use this information at your own risk!!

I don't believe anyone else has figured this out yet, if they did then I apologize for posting it again.

I overclocked my C90S tonight using ClockGen instead of Turbo Gear. Unfortunately, I can't go any higher then 2.71Ghz right now. I'm starting to think something is wrong with my mainboard because both TurboGear and ClockGen cause a BSOD when trying to overclock to 2.9Ghz.

To get ClockGen to work use version 1.0.5.3 ( http://files1.extremeoverclocking.com/5de9dc290b07559db869932b201a87f6/motherboard/utilties/ClockGen_1.0.5.3.zip) and under "PLL Setup" select "CY28551". This is the PLL of the C90S.

I'm very curious if other people who can't get TurboGear to work can use this to overclock to the C90S' limits. If this works for you please post! And if you feel friendly, rep would be nice too : )

 

It works I will definitely give it that. But it is not as good as turbogear. I was able to get to almost 15% OC when my computer crashed. Turbogear for me allows for a full 20%. I have a 6420 so I'm only at 2.13ghz as opposed to your 2.66.

BUT

This would be great for non-C90s laptop owners who want a little extra kick. If you can find and list the PLLs for laptops like the G or V series I'm sure this will see a lot of use.

 

Surprisingly this works quite well. Nice find. You also gotta remember that Turbo Gear changes the VCore as well which is probably why you gained instability, as well as heat dissipation.

 

Glad to here it's working nicely for everyone so far! I'm still doing some testing but at least I'm able to overclock a LITTLE with this.

Even running at 2.71Ghz my idle is still 51* Celsius and 65* under load. I should definitely be able to reach 2.9Ghz.

 

At the moment I'm working on determining what program reads the proper vcore LOL. So far I think Core Temp is reading correctly.

 

First off a big nod to you for pointing this out.

I decided to test the potential of barebone laptops to come and the C90s by seeing how high I could go using clockgen instead of turbogear.

Asus C90S
E6700
3GB Corsair Ram (2GB+1GB)
8600M GT 512MB GDDR2
Windows XP 32 bit



Removed ACE door and placed in on boxes with house fan under it on medium speed:




For each test i would first increase the cpu speed in clockgen by one "tick", apply, open speedfan to view temps, open cpu-z, and then open and run prime95 to put the cpu in full speed (non speedstep). I was stopped when I hit 2981. It froze immediately after I click apply. I restarted and tried it again fresh but it locked up just as before. For the final test I ran prime95 through the 2nd loop. It was not my intent to test for stability as I know the temps would be outrageous if it werent for my fan test setup. Here are the results:





Nice to see that the C90s at least allows further overclocking than 2.93ghz...although its not much. Great way to kill some time!

 

On another though....could it be that my 90W power supply could be holding me back??? Hmmm...

 

That's what I'm thinking, or rather hoping, at this point! If it's not that, then it looks like I'm going to have to RMA my C90S : /

 

Nice thing, I'll try it tomorrow.

How is you HDD running at 37C? Wich one are you sing. Mine stays at 55C! (at least my left hand isn't gonna be cold)

EDIT: You got the monster fan, nevermind

 

Your also stuck with a 10x multi. I would be capable of pushing my FSB further to match my ram since my e6600 is 9x instead of 10x. Very nice though, love the pictures and ideas. Tonight when my girlfriend goes to bed I will be popping off the ace door, getting out the soldering iron and popping a switch inbetween the lines of the fans and leading a 12v source to it, switch between laptop control and straight up 12v.

 

We really need someone to do my method but with a 120W power supply...

 

swoley2k, I will do that tonight with a box fan if it makes ya happy :]. Sadly my only camera is my cell phone and it will have to be in a while because I'm going to lay down with my GF will she is asleep :]:].

 

Yeah, if you can do it with the 120w and get higher than 2.93ghz it at least means it can go higher with a e6600. Be careful though. Dont jump from 2.4ghz to 2.93ghz...probably want to work your way up. you can do a picture by just doing a printscreen and paste into pain.

 

Ziggo,

Where are you going to tap the 12v supply from? As specific as you can please : ) I've got a similar idea and I can't figure out a decent spot yet.

 

I haven't completely looked yet, but until I find a suitable spot I'm going to take a lead off the + of the battery. I've tested this with fans, water pumps and so forth and it works perfectly, even when its in the laptop. I'll let you know if I find a good clean spot.

 

Hmm interesting idea. Since I'm lazy and you seem to have done this already, how fast does the fan spin with a solid 12v being applied to it? Full speed?

 

I hit 3 ghz

 

halfhalo thats great news. even though its only an increase of 66mhz from 2.93 it means your ram is running at the CORRECT 667! You have to be descriptive though. what os are you running? did you run it with a house fan and the ace door off? what were your temps? most importantly do you have the 120w power supply or the 90w?

 

Running 32 bit ultimate, with the laptop sitting on my carpet. Fully assembled. with the 90w. ill redo it with temps tomorrow. Its sleepy-time for me.

 

I can't even get this thing to stay stable at 2.71Ghz! I just don't understand what the heck is going on. Besides not being able to use my Intel 4965 card on battery mode and this overclocking issue my C90S works great.

Looks like it's going to need an RMA afterall : /

Anyway, come on guys, i found the key! So get to work and let's see the highest stabe overclock the C90S can handle!!

 

Guess ill keep at it tommorrow also since i have a e6700 and the 90w then halfhalo. i hope it isnt due to the fact that i have a 10x multiplier though vs. the 9x in the e6600. I would settle for just running my ram at 667. I vowed I wouldnt even use turbogear after installing ALL my games and testing them in standard then gaming mode and deciding it didnt do jack for me....But if I can get my ram at 667 it may be lookin into again.

 

Clockgen has problems here

In the PLL control, it reads the clock as x6800 huh

 

How is your memory out of sync? What BIOS are you running?

 

For those interested, and for reference, here is a picture of the PLL Chip:

 

My memory runs at 533 even though it's supposed to be 1:1. I'm using 902

 

Thats strange as hell...it should stay in Sync. I'm using 801...maybe I should try 902 tonight. Hmmm.....

 

No I've always got it at 533, even with the stock bios that came with it.

 

Can someone post a new link for Clockgen? gonna try doing some overclocking on my C90S with it, but the link seems dead.

 

Try this one... http://download.freewarefiles.com/files/ClockGen.zip

 

I just hit 3.1Ghz with my e6600, but it crashed shortly after. I was running the 3DMark06 CPU test a few times with 3Ghz, though. I had the Ace door fully assembled without any extra cooling and I was running Vista Ultimate 64Bit. TurboGear lets me overclock to only 2.71Ghz for some reason.

 

Ok, my machine just freezes the moment I hit apply and it doesn't matter how much the FSB is. My system is perfectly stable at 2.93Ghz, but with Clockgen it refuses to even go there, perhaps this isn't compatible with all C90S?

 

Overclock to 2.93Ghz with TurboGear and then change the frequency step by step with Clockgen. Don't make any big frequency jumps!

 

Does this program allow different modes of clocking?

Would be nice to have a turbo gear effect, 1 setting for gaming, 1 basic use, 1 for power save.

I don't think so I have looked but can personally only use it effectivly to do an extra overclock on top of the "turbo gear OC". I have been able to boost the standard OC of 2.76 to 2.86 Ghtz stable for over 6 hours in orthos small ffts, and 3 Ghtz not stable in orthos so pointless

 

What about t° during your extra overclock ?
Do you use a notebook cooler, or so ?

@+

 

Temp reaches 70 degrees but after a few minutes stress testing drops to average of 68 degrees , ran orthos small ffts for 6 hours before I stopped it. I don't use a notebook cooler and haven't done the vicious mod, sits on wooden table. I have however bought the new copper heatsinks from asus but found after much effort that only the copper heatsink for the GPU fits and after physical modification(they have done away with the southbridge heatsink in the C90P so the new heatsink is too big had to be cut in half!!) - especially effective when fans spin. Lowest temp so far is 67 degrees(drops to 50 degrees during stress test) with computer on idle on GPU but new cooper heatsink only been in for a day! Gonna pick up some faster 11,00 rpm fans soon and then a cheap x6800 and push over 3ghtz
cheers for seeing mistake with the and sign!!
