Hotdeal on a T9900 for $339 for my P-7811FX!

I will let you know how the cpu works for me, you have good stock 3dmark06 score. How is your score so high? Since I have installed programs and all my score has dropped from the 8700+ to around 8300 and I only have a few programs running in the background.

 

Well I think you remember Idiotpilots thread on 7805u 3Dmark posts. Its here:

http://forum.notebookreview.com/showthread.php?t=374381

I am on there twice and have the info attached to thread(Page 4).

 

Okay so I installed it and used ArticSilver's Ceramique Thermal Compound and at first my temps for my TZS0 where around 145F and my CPU went around 130F, I ran it though 3Dmark06 and got a score of 9709 and my computer has been running for about 30mins and my temps are dropping. Right now my TZS0 is 117F and my CPU is 100F and I haven't undervolted it yet, will do so here shortly. I didn't apply the ArticSilver to the chipset because there is a thermal pad on there, should I have taken it off and applied it to there? I'm using everest for the temps.

 

Sick!!! My CPU arrives this Thursday, got a tracking # and shipment confirmation. So glad I had a little patience with SparePartsWarehouse because my grand total with shipping for this processor is $307.50! Got my eye on SSD as my next big upgrade.

 

Anyone else get there's? I havent gamed on it yet but I notice things run way smoother.

 

Glad to see you got it.LOL. If your gpu is OK for temp's I wouldn't change out the thermal pad. LMK how you make out "undervolting" it. I haven't had a cvhance yet.

 

Right now I have it undervolted to 1.0875V and haven't had any blue screen of death. I haven't gone any lower but I'm sure I can take it down lower a few more times before my system crashes.

 

Got mine yesterday. I will install either today or tomorrow.

 

Undervolting? Looks like I'm gonna have to read up on this...am I correct to assume this should reduce temps and perhaps extend battery life?

 

Yes and yes
here is a link to undervolting, My T9900 is undervolted to 1.025V

Wow! Never heard of undervolting prior to this. Thnx for the link very informative and convincing...I will be doing this as well once I get that puppy slapped in there (probably tomorrow or sat). I'm curious to do a before and after just like in the thread for undervolting and see how significant of a temp drop is achieved. Cheers on getting from 1.0875V down to 1.025V!!

 

I saw a big temp drop so it's worth it, there really isn't a down side to undervolting.

 

Mine has shipped and I have a tracking number. They are telling me monday. Can you guys post your idle temps on AS5 versus the stuff in the HP package. I'm just curious.

 

What are wanting xarthos?

 

20C or less, depending on your ambient with the Shin Etsu. It may be slightly lower with better compound.

 

Ok...I think I may go ahead and tackle the CPU upgrade tonight sometime. One thing however has got me a little concerned. According to the "teardown" thread there is a gap between the NB chipset and the heatsink assembly that is bridged with a TIM pad. Any body have an idea about how wide this gap is in millimeters? I'm concerned that I may render the current pad unusable when I pull off the heatsink, so I need to consider what I may use if that happens. I have AS5 left over from my desk top builds for the CPU and I cannot find IC7 anywhere locally but the local electronic surplus actually sells these types of pads...just would like to make sure the thickness is OK. Any ideas?

 

No load -30C-32C with thermal grease sent with processor. (Haven't undervolted yet) I have noticed my multiplier go up to 12x for 3197MHz under load. So that would put it at 3.2MHz and not 3.06 MHz? Anyone else see this. Using CoreTemp and CPUZ 1.52 64 bit for temp's and info.

 

I left the thermal pad that's on the chipset, not sure if I should take it off and add articsilver there like I did the cpu. What do you guys think?

 

thanks man. It really sounds like that stuff works great. I've got a lanparty starting next Friday and going all weekend with some buddies and I want the new chip to up and ready for it. We will see if the Monday estimate was right I guess.

 

I don't think I would put it on the chipset, unless you messed the pad up when changing the CPU. Just did everest on the CPU. Yup. 4% overclock on the CPU running at full load. 3197MHz. I thought this couldn't be overclocked?

 

Banjo
Using everest what kind of temps do you get on avg for both gaming and just playing around on the computer? Thats kinda cool the CPU is overclocked 4%

 

Think I'm just going to be real careful with the pad when removing the assembly. Also was thinking about using the Shin-Etsu that came with the processor but decided I will use the AS5 instead. According to Shin-Etsu's website http://www.microsi.com/packaging/thermal_grease.htm there are 4 versions. Cannot tell which one is included with CPU.

But according to this TIM performance test http://benchmarkreviews.com/index.p...k=view&id=150&Itemid=62&limit=1&limitstart=12 AS5 and Shin-Etsu's best are tied for top honors, so going with the for sure thing.

 

Got it in! Been messing around with laptop for a while and Yes! it does feel overall more responsive. Between this and the Win 7 upgrade seems almost like a new system. Thanks to the info provided by strife1013 I will play around with undervolting and temp differences over the weekend.

 

you could download cpugenie and give the trial version a whirl. its a good program and not very expensive but if you prefer a free undervolting program then use rmclock but in order to make it easier for you use cpu genie trial to find your lowest voltage using the voltage optimization wizard it has on the program. then just slap those results into rmclock.

(the voltage optimization wizard can take awhile so be prepared to leave it alone for awhile.)

 

Sounds like a good method...I will look into it. Thnx. BTW how far off performance wise is this T9900 from your x9100?

 

Since you can't overclock an X9100 in the 7811/7805 series the performance should be identical, the T9900 is effectively a locked X9100.

 

The the more important differences is that it runs much cooler and uses less energy.

 

"Since you can't overclock an X9100 in the 7811/7805 series the performance should be identical, the T9900 is effectively a locked X9100."

Oh, I see. Yep I am extremely happy with the performance gain from observational point of view (w/o any benchmarking etc).

@ citizen panda, are you using an overclock program or something to get 3.4ghz out of this?

 

You have basically the baddest CPU you can get your your laptop, and it's a fine performer. As for overclocking, the 7811 is locked so no overclocking for us, his G60vx is overclockable, I think you can use setfsb or similar on that laptop.

 

Sounds like a fairly open bios. I'm used to this within a desktop environment, but even then rarely if ever OC just simply because I get enough juice for my needs...although I do like seeing how far other's can push their rigs.

I think I'm gonna try the cpugenie method of undervolting...and let it run overnight. The more I read about undervolting the more impressed I am with the potential benefits.

 

ok guys mine is arriving this afternoon. Seems everyone has had good results but I will get back to you guys with some test results once I get it in. I have a lanparty this coming weekend so I will probably put it in tonight.

 

U should be happy with it, I am. Temps are a little warm but the computer runs so much faster.

 

Box and everything looks fantastic. Exactly like the previous picture in this thread. I'm working on it now. I'm going to use the stuff that came with it. This package is outstanding.

 

Im interested in hearing your 3dmark06 score and seeing your reaction to the new CPU, also I would love to know temps and seeing if I made a mistake going with the ArticSilver over the thermal grease that came with it. Also let me knoe if you use all of it on the cpu or only like half.

 

I'm running really cool in hwmonitor under windows 7, max so far has been 25C as far as I have seen. It's been five minutes since I booted. Windows 7 detected and installed as T9900 and said I need to reboot. I haven't rebooted yet since looking at the temperatures using the shin etsu is so much fun. I did what it said and tried to use all of it. I used almost all of it just like the directions said. At the moment I have to say this stuff is better than AS5.

So this is the easiest damn thing I have ever installed. Really easy.

Check this out:

 

Holy crap ! Are those temps for real...you're averaging about 8-9 degrees cooler than I am with AS5...of course I got a long cure time ahead of me...but with temps like that I amy be changing over very soon! Hey is there any difference between the cooling pipe in the 7805 vs the 7811? If not I don't see any reason to continue using AS5.

 

I think I might switch out the thermal grease, my temps are no where near yours. I run on avg. 100F for the CPU and the TZS0 is in the 130s just under normal condiations. Did you do anything to the chipset? There is a thermal pad on there, did you replace it or just leave it there?

 

Temperatures are all holding about the same. I'm going to leave it running at least tonight and I think somewhere it said 72 hours but I don't know. I went and did some benchmarks. Battleforge has a built in benchmark system. I went from 50-60fps max to 140FPS max in the benchmark at 1680 by 1050 same settings on my external monitor which I game on primarily. It does a min, a max and and avg. They all doubled or tripled. I'm blown away by the differences so far. If I had more of this thermal grease and I was skilled with taking apart the laptop I think I would go hit everything with it based on the current temps. I haven't gone over 45c running benchmarks.

I followed the directions in the kit. Shin etsu from the kit right on the middle of the chip. Nearly all of it. As much as I could fit neatly. Made sure it looked neat. Plopped the heat sink down and booted to windows 7. I'm running 21c on both cores at the moment and it's been like 2-3 hours.

I believe the TIM being used is Shin-Etsu MicroSi’s G-751.

 

Those are real good Temp's. I use CoreTemp to check mine.

 

Those were temps I got when I had my 7805 (see my post on page 12). The T9900 now sits in my Asus @ 3.5ghz (29C idle).

 

You should not have spread it with anything - since now you contaminated the thermal compound and reduced its thermal conductivity properties. Thermal compound should only ever come in contact with 3 things out of the tube - Heatsink, CPU & atmospheric elements.

 

spread isn't really the correct term. I had a bit hanging over the side that would have gone on the chip. I swiped that off with a screwdriver. I should probably edit that post.

 

Interesting, my temp range actually increased by 1-2 degrees. Not only that but the temperature seems to fluctuate while idling quite often, whereas with the AS5 it pretty much consistently stayed at the low end of the range during idle. I guess I'll keep an eye on this for a few days and see if I end up changing back.

 

I changed out the thermal grease. My temps seem to be lower. I am getting 110F with the TZS0 and 85F with the CPU. What is the TZS0?

 

Yeah see...that's about where I was before, 29-30 Celsius (idling on the low end) with AS5, now about 32-33 celsius (also idling) with more fluctuating. Do I remember right that you were using AS ceramic or something and not AS5?

 

I was using AC Céramique and I'm getting better temps with what came with the CPU although I put all of the thermal paste on the CPU. I'm getting a drop of like 20F from the TZS0 and CPU which is huge, was running idle at 120F for the CPU and now it's like 85-90F idle, huge drops in temps. I'm also undervolting.

 

I too used all the TIM that came with the CPU...and it seems that our temps are in line with each other. Although I am not undervolting yet. So far I am liking what I saw with the AS5 better but I will wait the 72hour cure time of this stuff to see. I am surprised however by the large temp difference between yours and xarthos system being that they are the same model now using the same TIM. There must be some other variable accounting for this.

 

I'am like getting the same temps, it just his CPU runs way cooler than mine for some reason. These temps are way better than what I was getting with the AS Céramique.

 

Maybe a good cooling stand/pad? But congrats the significant temp drop you've achieved.

 

I have that foldout targus thing that you can use as an elevated stand. I use it flat folded on itself under my laptop so it raises the computer but thats all I do. It's elevated maybe half an inch but I still went from Idle in the 35C to 40C range to 15-20C range.
