Fear the c90's cooling! 8600 DDR2 getting ever close to stock 8700 speeds!

Man after experimenting with my c90 for a bit found some nice results.



THis is using artic silver 5 and a zalman cooler and modifying the voltage and fan controls.

Sadly enough I got it up to near 4650, but once it is was done, c90 bsod'd.

Did some other tests, like reducing cpu voltage and cpu throttling to see if it affected the gpu. CPU temp actually has nothing to do with gpu really like we all believed.

 

Zalman Notebook Cooler I assume . Very nice results, my 8600 GT can barely hit 550 core/500 memory without it Bsod'ing on me and I've tried everything. AS5, Lapping the cooler, removed heatpads etc, what are you GPU/RAM frequencies?

 

Sorry for the noob question but what program do you use to change the cpu voltage?
The ones I've got only show me the voltage and don't let me change it.

Really nice results by the way. Now forget the zalman and use some liquid nitrogen to reach 8000 in 3DMark06 and you'll be my hero forever

 

For that test I believe it was gaming mode and 600/1425/535. I can actually overclock the shader past 1500 with it being stable but have to reduce memory to prevent it from overheating. My memory if I only overclock that can reach 580. And my core overclocking it can reach about 640-650 but I'm still in the process of finding the best combo. Especially since 3dmark, the firefly test which I believe is shader intensive is the one that crashes my card. If it passes that test I know its fine. But shaders give you a nice boost in 3dmark score.

Not a noob question . I had to search myself. Its called rightmark cpu utility. (RMclock) Actually I'm somewhat confused about the relationship of the cpu temp/voltage to the gpu. It seems the fans don't matter but there has to be a voltage relationship. Since my c90 can handle those temps, there has to be a voltage issue since it artifacts with overclocking and not on gaming which is just higher clocked but same voltage. I tried increasing my gpu voltage by .1 and it did not help. Maybe if I go higher but thats risking it.

Hehe I'll try 8000 but my goal right now is 4700.

 

This is very nice and im glad there is a new post regarding c90.

I was doing some test a while back and found that the shader clock doesnt matter as much in vista as it does in xp. I tryed a shader of 1150 and 1200 and got literally the same score (4400) but the same test in xp gave me 4535 and 4586. You may try lowering the shader and raising either the core or memory to get more points.

 

FYI, I can at best get 600/1200/550 and thats with the ACE door off and the laptop sitting on a small house fan. With that I can get over my old 4400 score at 575/1150/550 but forgot the exact score (not higher than 4500). So you should be able to get much higher since your card can clock higher than mine....maybe try the info from my above post and with a house fan under it. PUSH IT TO THE LIMIT!

WoW and that's the DDR2 one. I wonder how the GDDR3 can hit.

 

Yeah, I wish I had one. THat would be great fun to overclock that thing. This thing's main restriction is heat. Even with all the mods it still overheats. Mainly the memory. The core can take it but the mem can't.

 

I heard the 8700M is quite overclockable.
I can't wait to get my hands on a new GPU.
After a GPU upgrade my other concern is the RAM since it is clocked 533Mhz in standard mode and just
612Mhz in overclocking mode (my machine doesn't go higher than 15%, 2.76Ghz).
I wonder how I can reach these 2.93Ghz in TurboGear.
Otherwise my RAM will be the next performance bottleneck.

 

On a MXM-III port though. It's 35W, ifi t comes with the C90S/P, it will only be 25W so less OCable I guess, except if it's a new revision on the 65nm

 

a 9500m GT could very well be an 8700 die shrink while a 9600m GT could be the 8800 die shrink. We might be seeing these upgrades...Holy crap! We might actually be getting the promised upgrades from Asus! And they might actually be attainable and useable! Huzzah!!!!

 

Nice work theForerunner. very good for driver-level overclock.

 

Thanks Ken. I promise I won't fry the card.

 

Don't worry about that, have fun with your new video card.

 

Ill tell you right now that pushing the voltage on the 8600m gt dosent do much. I dont think it goes above 1.3 because ive tried to put it on 1.8 volt and nothing happend. There isno program that will let me read voltages on the video card. I think youll have to acctually pin mod it to get above 1.3 volts.

 

I have a question on cooling cause my GPU sometimes gets rly hot. How can I reduce the temp, except with cooling pad? I dont have much experience with this, maybe someone can tell me what I have to do (thermal paste or something?) and maybe with screenshots.

 

Very nice results Forerunner!!

I have one question: Did you try to OC without the Zalman cooling pad or with the Zalman but no arctic silver paste? And if so, which one did you find gives the major boost for you OC?

Thanks beforehand.

 

What program did you use? I might try a few increments at a time. Hope youdid it ssafely, its not recommended that you go above .1 and you jumped .5 though but it seems it did not change the voltage. When I increase the voltage the core does go higher but the memory craps out from the extra heat.

Thermal paste is good. Umm being in a well cooled place makes a big difference. When my room is nice and frosty the gpu temps stay consistantly lower.

Well did arctic silver first because I got it first. TOok off the thermal pad and used arctic silver and saw a nice drop in temp right away. THe cooler is more of a supplement. Because it does not seat the c90 perfectly but it does help.

 

So I need to put thermal paste on the gpu, but how much/thick I need to put it on the gpu?

 

If your talking about AS5, follow this Artic Silver Application guide(PDF).

 

Im using bios overclock... is there a program that does it through software. What are you using??

 

acctually lol i jumped to test it real quick and nothing 1.8 volts! hmmm i really want to know what software you are using. I really am bummend you didnt keep the ddr3 card when you were testing it. I got mine to max at 5700 points at 90 celicius max temp. My goal is 6000. Help a brother out here. I know if i increase voltage i can do it.

 

You willl need Nibitor to edit your VBIOS to modify your voltages. I do not recommend anything above .3v the stock voltages. After the edit, save the ROM and you will need nvflash and the HP USB Flash Boot Utility to flash the ROM in DOS. Keep in mind not to make any major modifications, especially the memory timings, you can seriously brick your video card.

 

thats what i did D3X and it dosent work! Is there a program that can check your video card voltage?

 

DDR3 card? I never had a dd3 card.Yes use nibitor to change your volts. I might try steady increasing volts more.

 

Maybe the DDR2 card is better for overclocking due to the high temps form the DDR3 model.
I can't imagine pushing the DDR3 very far if the heat rises so exponentially <-- I hope that's a real word.

 

Alot of options for the C90S to gain performance, atfirst were were just ocing the video card, but when a new version of clockgen came out we were able to OC the cpu, now there are new programs for raising the voltage and thus making higher clocks more stable and even new drivers to raise performance too.

Id like to hop in and do some testing but I have a runt, my gpu past 500/500 artifacts or locks up and cpu overclocking alone wont do much (except maybe i can try for the #1 spot for wprime benches for laptop)

 

Is that a challenge vicious? After I find out my gpus max, I'm going straight for the cpu.

 

ROFL! interesting. May I join in on the fun?

 

I attached my max... but the problem is if i go aobve 650 core then my screen just goes crazy! these weird lines but I can see 3dmark or the games run fine... This only happens when i do gaming mode. I tried undervolting my processor to minimum voltages and still no scucess. I just htink that for some reason the voltage applied to my gpu dosent go above 1.35 volts. Is there a program that can meassure gpu voltage.

 

Oh you have the gddr3. I was about to say WHAT??!!? Nice scores.

I know what your talking about the lines. It has to do with the cpu clock speed and voltage. Increasing the cpu clock and fsb/ram directly affect the gpu core's ability to overclock. Thats mainly what I am tinkering with.

Actually the cpu fans blasting does help the gpu stay cool. With my c90s fans cranked up 2nd to highest the gpu never goes about 81-82 with 575/1250/530. But thats only on overclocking so that reduces the core's ability to overclock.

I'm not sure if there is a program to measure gpu voltage. I would be interested in that too klok.

D3X. Two words: bring it! Got the cpu clock to 3.05 and thats the max....for now.

 

What were your clocks here? I know rivatuner shows inaccurate clocks. Also are you on 32 bit vista or 64 bit?

 

Hmmm...I wonder what the max is for an E6420? Heh I'm willing to take bets on how high you guys think this thing can go. I think the last time I tried to use another program to OC my CPU I was using my 90w psu which has been proven to be faulty but with my new 120w well I guess I'm gonna push it to the limit!

 

did anyone try overclock not via turbo gear but via clock gen. maybe turbo gear messes with the voltage of the gpu...

 

Yeah I used clock gen and got to get 3.05 ghz.

 

had anybody tried a quad core yet that we know of? I have a feeling it will work in the c90 just not officially. I would only use it for benchmark run not my perma cpu but I definitely do not have the money to play with to try.

 

Sauce,

When ziggo first mentioned using rmclock a good while back in another thread I was able to get futher over 3ghz with my e6600 than with my e6700....so the lower cpus may actually do better with rmclock than with newer cpus. Also the psu issue is a good point. Back then I still had my 90W psu. Now I have a 120W but dont have my e6600 anymore!

Forerunner,
Sorry which cpu is that? Also do you have 90w or 120w?

Vicious,
If I wasnt so tired of messing with thermal paste and heatsinks, I would pop my q6600 in and give it a shot...I still might though...convince me.

Right now Im using my e6700 with 120W

 

Ugh, nevermind. I forgot I would have to take the q6600 out of my desktop to do that....someone else do it

 

This website will actually let you configure the C90S with a Quad Core!!!

https://www.interpromicro.com/comme...=90000263&orderConfigID=0&czuid=1200941191907

It says so in their short description, too: Asus C90S, 15.4" WSXGA+, C2Duo/QC ...

It seems to me these resellers don't even try the QC.
I think they just sell the machine with QC because it's pin compatible and supported by the chipset.

 

Yeah, be nice if there was some way of testing the rep of that.

 

For those of you interested, I have created a custom autoinstall project for Windows XP 32 bit. Even those of you not using that OS, I would appreciate it if you would check it out. Theres some good fixes in it and the readme is on the post.

CHECK IT OUT! http://forum.notebookreview.com/showthread.php?t=226854

 

Man this is bull... I want to make it 6000... just 300 more points come awn!

It sucks because when the lines do happen it dosent affect prefomance... could it maybe be the lcd?

 

stick the house fan under it with the ace door off

 

Yeah mine is e6600. With 120 W. Just got home. Spring break this week. Gonna ty increasing my vcore because it craps out at about 3.04 ish.

 

Heres the old thread. I suggest everyone reads through it for some good info. My test are in it to with both the e6600 and e6700

I just got an EEEpc not too long ago and have an extra watercooling pump lying around, Thinkin of maybe trying to install it . It wont be as portable thats for sure, but I got my eeepc for mobile so.....any thoughts??

 

sure, why not? Go for it!
