P-7805u GPU Overclocking Guide for Newbies

I started to get that on 186.03 after a while, so i scrubbed the driver and then installed a new one. There might have been an easier fix, but that was the quick and dirty way to solve the problem

 

i tried the old driver and a new one but the samething happens what driver r you using

 

Was the back of your laptop elevated at all? 87 is HOT but generally still in the "acceptable" range for a laptop GPU (90c is usually the operating limit). Raising the back of the laptop to open the vents up more can easily drop temps 5c or more on the GPU.

 

So what would happen if I maxed out the sliders on the Nvidia control panel for overclocking?

 

You would have a good chance of instantly going into thermal shut down or your chip would fry almost immediately.

OCing is a step by step process... not something you just try to max out and hope for the best... thats what kills hardware. While a good OC can be ran almost constantly, things like you're talking about give the whole process a bad name

 

I bet there is some kind of watchdog timer that will cause the notebook to lock up or shut down when you try that.

 

Allright, I need some help with a problem. About five months ago I posted here about a DRIVER_IRQL_NOT_LESS_OR_EQUAL BSOD I was getting. I was on Vista x64 then, and using the Dox drivers, and I just gave up on overclocking. Now, I'm running the normal nVidia drivers after a fresh install of Windows 7 x64, and I thought I'd try my hand overclocking again, but I am still getting the BSOD. I've narrowed down what causes the BSOD: whenever I apply the overclocking profile (710,950,1750) and start a game, the game runs for a minute then BSODs. If I play the game without overclocking, no problems.

I have already reinstalled the drivers, but no luck. Please don't just say "don't overclock" or "google it". I have a P-7805u, like everbody else, and the only upgrade I've made to it as adding another harddrive (identical model), and I keep the laptop elevated at all times. Please help. In the minute the game runs I've seen the boost in performance, and I would like to keep it.

 

Have you tried overclocking it LESS? Not every machine is going to be stable at the overclock someone on the interwebs posts about, going straight to 710/950/1750 is a pretty big leap...

 

Yeah, I tried that. Any overclocking at all, even just by 1, "triggers" the BSOD once a game loads.

 

Have you tried overclocking with different drivers?

 

Yeah, I've tried with the Dox drivers, no luck.

 

What program are you using to overclock? Sounds like a bad setting or something. Personally I'm using the latest MS Update pushed driver with Nvidia System Tools w/ ESA without issues. I used to use ATITool but it hasn't been updated since the dawn of time.

 

I scored a 8900, overclocked 720/970/1850 on my P7805u, it seems a little low though...

 

eh? i cant come anywhere close to those clocks. Count yourself lucky.

 

Yeah LoneRaven you are lucky. I use 660/1650 for core/shaders because 670/1675 is completely unstable. As for mem I use a conservative 850MHz, but I tried 900 once and it might have been slightly unstable.

 

Let it be known that I had to part from this awesome machine and got a Asus G73JW-A1 Much better OC capabilities, but I'm gonna miss my P7805u!

 

I have a 78u5 with t9400 cpu , Corsair Force 60 SSD drive ,Windows 7 32 bit

I get 10600 without OC

Hell there, I figured I would post this here because you guys seem tech savvy and have the p7805u fx.

So after using this computer for about 1 year the quality of the games has dropped. They basically get waves of lag. Even if I turn the graphical settings down I still get lag. The CPU runs around 80 C when I game so I figured maybe that is causing the lag.

I took my computer apart and I am not very technically savy but I learned that you need to use thermal compound to replace the heatsink, the part that is confusing for me is that I thought there were 2 processors, so why does the heatsink mainly rest over one, and what I believe to be the other processor has a what I believe to be a TIM pad on it. Why are they not evenly made, or maybe I don't really know what the difference is.

Are these temperatures too high? Am I going about this the correct way? I am only replacing the thermal paste on the one that does not have the pad. And I figured cleaning out the dust might solve the issue.


Anyone else with a similar issue who fixed it? I did a factory restore thinking it was software issues, and MW2 online now doesn't really lag, yet ME2 lags in single player still and so does MW2, while when I first used the laptop it ran fine.

I don't think it's the GPU because the temp is about 60C when I game.

Any help is super appreciated.

 

There is only one CPU (it has 2 cores but you wont see that, you just see one CPU).

There is also a GPU.

And there is a northbridge.

I'm guessing the northbridge is the chip that has the TIM pad on it.

I would replace the paste on the CPU and GPU, but leave the TIM pad on the NB.

EDIT: I have attached what I think is an image of your CPU, GPU and NB:

 

Yea thanks, you are correct. My CPU temperatures dropped by about 40C from cleaning out the heatsink and applying some new thermal paste. However the game I am playing recently is Crysis and I get lag during gameplay at the top resolution 1440/900. I get no lag when I put the resolution down to 1280/786(or w/e it is). But when my computer was running fine I could run games like ME2 and MW2 on top settings fine. Now it doesn't seem so. The GPU temp doesn't really go over 60C when I game.

I can't figure out what the issue is. Does the computer simply get this bad overtime?

 

Sounds to me like your CPU is throttling.

Download throttlestop, it should help.

 

What should I change using throttlestop? Which settings and to what level?

 

Tick the box for clock modulation and set it to 100% and tick the box for chipset clock mod and set that to 100%.

I think there is a file that comes with throttlestop which will explain how to use it.

I dont have throttling so I'm not sure.

If throttlestop doesn't help, I can try to mod your dsdt for you.

 

Thanks for the help, I did the thing with throttlestop, on 1440/900 resolution the game is considerably less able to perform than when I play not fullscreen on 1280/768. I feel like my computer should be able to play it fine given it ran ME2 perfectly.

What exactly is modding the dsdt?

 

Modding the dsdt helped in this case:
http://forum.notebookreview.com/gateway-emachines/298342-7811fx-new-heat-issue-acpi-tzs0-25.html

Not sure if your notebook has that same problem.

 

No, I fixed any CPU heat issues by cleaning the heatsink. While gaming the temp of the CPU is less than 40c and the GPU doesn't go over 60c.

I even have the GPU overclocked a bit to help with performance, but I just can't seem to get it to work how it should, and I don't really know what else to do.

 

What about your TZS0 temp, hows that?


To increase the multi above stock with throttlestop you need to have an extreme CPU (or one with an unlocked multi). And yes, it could help.

 

Could you point me in the direction of a program that gives that info, I can't find one.

How would you unlock the multi, do you think it's recommended on the p7805ufx?

 

Download CPUID HWmon.
That should give you all the temps (I think).

If you want to increase your multi, you need to buy an X9100 (or any other extreme CPU).

 

Using speedfan I see normal temperatures, it gives the temps of the GPU, HD, both cores, and 2 other temperatures simply called temp1 and temp2. All are normal temperatures.

The lag in 1440/900 is evident even when I start playing, so I don't think it is caused by overheating.

 

If you lower the res and lower your cpu frequency, do you get the same lag?

 

I don't know how to change the cpu frequency. It does not lag on 1280/768 versus it does lag on 1440/900.

 

You can lower the multi with throttlestop.

 

Doesn't that lower the output of the CPU? Wouldn't it cause it lag more? The setting is at 9, how low should I set it?

Thanks for the help.

 

Well I only suggest that you lower the performance of the CPU just to check if that is your problem.

If you lower the multi to 6-7x and lower your res, do you get lag?
Is it the same as 9x with the high res?

If you do, that might mean that the lag you see is because your CPU is too weak.

 

If it was once capable of playing games like MW2 at max settings, but now unable, can the CPU get weaker over time?

And yes, if I lower the multi I get lag in the 1280/720 resolution, and with it at 9 it lags at the 1440/900.

I still get a very small amount of lag even at the lower settings sometimes.

 

I missed that part.

You should be able to get it back to normal, though I don't know how.

System restore maybe?

 

Did a factory default restore, I feel like there was improvement, but not to how it used to run. Basically out of ideas, except overclocking the CPU which I don't really know how. I overclocked the GPU already just trying to get it to run how it used to.

 

Well I'm out of ideas, but I just looked at your user name, nice choice lol.

 

lol thanks.

 

So get this, a guy in a different thread mentioned upclocking, so I googled it, read through a different thread, and basically all I needed to do was in nvidia control panel change the power management mode to prefer maximum performance.

Wow after all that, such an easy fix. I think you may have been correct about the throttling, he called it "not upclocking properly" but regardless thanks for the help.

 

As a side question, during all this I did a factory restore and during updating windows I noticed some of the updates add things that run like the .net optimization and other windows programs that tax the CPU usage so I restored to the point before any windows updates to try to get the computer running well.

My question is, is it a pretty bad idea not to get the windows updates even with Comodo firewall set at high settings and running malware bytes periodically?

Anyone else get lag from the updates or is it a good idea to stay current?

 

hi guys,

i dl'd the NVIDIA System Tools with ESA Support Version:6.06. It should be the same or better, right?

i havent tried OC'ing a laptop before, does the cooling of the p7805u sufficient for additonal heat that will come from this OC?
And on average, what FPS gains do you get from games?(sc2, civilization V,crysis,da2,etc)

Stock WEI with ocz agility 2

 

what driver version are youm using? Also is this the WEI after video OC and what settings if so?

 

hi again tanware,

i will be updating it now to 267.76(the one recommended by nvidia system update).

these are WEI for the stock settings. i want to OC it since i'm playing crysis 2 now on "very high"(mid 20s-mid 40s FPS) settings and wanted to play on "extreme" settings if possible with an OC of the GPU. thats my only concern now really, with your OC's how much gains did you get?

****i play with gamebooster premium(theres a free version too)

 

Hi, I'm new to this kind of stuff and have tons of questions , I read around but still got a few questions... (And boy am I glad to find this forum, it help me a lot lol)

First of all about video driver... even though I've been a gamer for a long time I still am not sure what exactly the difference between one driver to the next. After trying a few I can say for sure that newer driver doesn't give out better performance... in fact I took a hit from my gateway's original shipped driver to the new one gateway has on their website or the new reference driver that nvidia have. The good things that new drivers give is the ability to run directX10 which the original driver can't. So new drivers means more feature that can be used for newer games rather than faster speed I'm guessing? I'm hoping to be able to find a driver that can run as fast as the original driver but can use some of the newer features too xD... or am I out of luck lol.

Secondly I just ran 3DMark06 with an OC (oh btw I'm using gateway p-7805u with everything as original except updated drivers) which give me a 8900ish score... which is... about the same when I first run it without overclocking strangely... but what concerns me is the temp, I'm running speedfan in the background and it says at peak testing the core temp reach 100-105 degree which sounds scary to me ... My core regular temp is in the low 70s (about the same as my room temp) and for it to shoot up so high when running 3D... is that normal? I'm getting a zalman NC-2000 for a cooler in the next few days to help with the temp but still I can't see it drop too much... is there a "safe" temp that the gpu should be running? I'm looking at various screenshots in this thread and there's no way even with cooler I could achieve temp like 50s or 60s that some people have posted :O

 

what are the OC settings?

 

Aloha guys,

Been playing around with OC'ing my CPU and GPU to safely juice as much performance out of my P7805U as I can.

I've been tweaking my settings for the GPU using nVIDIA control panel with performance tools. Current settings:

Core: 685.7 MHz
Memory: 891 MHz
Shader: 1600 MHz

Driver Version: 275.33

These settings yield a 3DMark score of ~10730

My core and memory clocks are fairly close to what I expected. If I go up to the next setting on either of them, 3DMark will crash.

I'm a bit disappointed with my shader setting though. I was hoping to get it to 1700 MHz. It steps @ 50 MHz, and at 1650 it will crash 3DMark at the CPU test, which I found odd. The first two graphic tests run fine.

Anyone know why this may be happening? Have I hit the cap? I had my fingers crossed hoping to get over 11K 3DMark, but if that can't happen... Oh well

I am running 3DMark06 with ThrottleStop as well with CPU multiplier set to 13x @ 1.250V (3.46 GHz). I haven't tried changing this yet under the mentality that it should be helping, not holding the system back.

Any help is appreciated.

 

For anyone who happens upon this post, seeing as this is an old thread, I'm running stable at 700mhz core, 950mhz memory, 1800mhz shader. I've obtained a score of 9699 on 3DMark06.

My temps go too high at anything above these settings and the video card driver crashes. I'll be removing and cleaning all heatsinks and applying new thermal paste (IC7) to the GPU, chipset, and processor. That should drastically reduce temps and allow me a higher clock.

I'm on a stock P-7805u.

 

What is a safe operating temperature for the GPU? I'm idle at about 70*C and I peaked at 99*C during MSi Kombuster GPU stress test.

I'm on a stock P-7801u FX.

Thanks.
