Overclocking the P-6831FX

Starting a thread for the overclocker in the bunch. I was curious to see where other have been able to OC the 8800GTS in their FX.

I was able to OC to 620/920 GPU/Mem. My temps were stable after 40 min of stress testing at 65C and with no artifacting. My 3dMarks with the stock CPU was 7307

Just a small OC of +40/+40 returned a 3DMarkc of 7122

I use nTune from NVidia to OC my GPU.

So the question is.. How far did you push your 8800GTS and what was your 3dMarks after Overclocking.

 

I would like to OC, but I want to replace the TIM of the 8800M GTS to AS5 first.
Seems this is a difficult task that you have to take apart the whole laptop.

 

I don't think overclocking on FX is worth it for few reasons. One being the BIO isn't OC friendly. I know we are talking about GPU, but we have 0 control over FSB, voltage, fan speed etc. Because we can't control the fan, OCing the GPU slightly will cause slight temperature increase. We all know more heat isn't good. Plus, there is the question of whose going to be first rip apart this notebook to access the GPU?

I don't think its worth the risk OCing the GPU to gain 1-2fps in Crysis.

 

While you bring up some good points I don't think the fan speed is going to effect anything, laptop gets hot fan goes on >.>. The part about voltages however is a concern that I've posted before. The adapter that comes with the laptop seems to be specifically designed to support the laptops stock settings and nothing higher. When I tried to overclock it ran great, till my adapter started literally srceaming. When using my m9750's adapter I had no problems at all and when returning to stock settings my fx adapter worked just fine.

 

The settings I've been using are 640/940, which have been running very stable with no artifacts at all.

Even going to 650/960 and beyond, I did not have artifacting issues, although I did get the "You're video adapter has stopped responding" message, and the clocks were set to 200/200, after running the first GPU test on 3dMark06. I'm wondering if this is due to exceeding the voltage capacity.

With respect to heat, this laptop has an extremely effective GPU cooling setup. Using a 640/940 overclock, according to NVIDIAmonitor, the temp never went above 71C, and that was for a 3 hour gaming session. Extremely impressive for a laptop, to say the least.

 

My adapter makes a decent amount of noise with everything at stock out of the box. I've been a little bit concerned by this.

 

Mine does as well. I'm not too worried at this point.

 

Yah they make noise, like put it right up to your ear and you will here some strange chirping sounds. When you overclock it though you can have it a few feet away from you and here those sounds. When using my m9750's adapter almost twice the size it didn't do that.

 

Does that other one make noise when the laptop is stock?

 

If held it to my ear I could hear some noise, but it didn't sound like anything to worry about. The only thing that had me concerned was the stock adapter when I tried to overclock.

 

When / If you switch to Penryn and/or SSD drives, overall laptop temperature will drop, allowing you to overclock GPU back to stock temperature.

 

Cool. I was also a bit concerned about the little noise coming from the power adaptor. I guess this is normal.

It's not that loud, but I'm rather new to personal laptops and I'm used to my adaptors not making any noise at all. With the exception of one adaptor, I know, which was meant to delay an accidental power shut down. I guess the one for the laptop has the same function.

 

You can always go a 150 watt AC/DC supply like Dell uses on it's XP line. Try on-line to check the plug/jack size.

 

Hey reading all about the power issues (like the hissing etc) I want to pick up a power adapter for my new lappy, I plan on OCing it a little and was looking at the 1730 adaper like this:

http://accessories.us.dell.com/sna/products/Power/productdetail.aspx?c=us&l=en&cs=19&sku=310-8537

think that should work alright?

 

yah that should work just fine. As long as the adapter can can put out 19.5V and is at least 120+ watts it should work just fine.

 

Sweet. How will I know if the connector to the laptop is the correct one though?

 

Good question! Wait till you get your laptop and compare. I ran a core 560 for two hours with no noises coming from the supply.
Not very scientific. YMMV

I have no simple way to measure current without cutting wire on the DC side.

 

one question I have (I love to OC) I thought that as long as you didn't up the voltage you were just increasing the core/shader/mem on stock voltage, how is it affecting the power since its only running on higher clocks with stock voltage?

 

high clockrate needs more power.

2 things in OC needs more power:

1. raise voltage
2. raise frequency

 

Well, voltage is only part of it - higher clocks will draw a higher current (wattage) regardless.

 

Absolutely, I raise small amounts as to not stress ac/dc adapter or thermal GPU loads.

I like using the nTune utility. Unlike flashing the card on my Dell, the nTune does not set your clocks in stone in case of a hard crash.

Some Dell users ended doing blind re-flash to try to salvage blank screens.

When we get enough users we can start an OC thread.

 

I forgot to mention that our 1705's and FX notebook plugs do not match. You will have to find a web site that is specific, or buy, cut cord and find a matching plug at radio shack or other.

150 to 180 watts at 19VDC, at best price, should work fine. It appears we have 120W supplies at 19VDC X 6.32Amps. Our 1705's had only 90watts.

 

I swapped out the stock chip for a T9300 and 2 7200 rpm segates in raid 0.

3d mark 06 8798
mem bandwidth 4200

file system benchmark 77mbps.

want to find a way to OC cpu on this board. cpu idles at 37 so not worried about heat of OC'ing CPU some. This machine is memory limited now. anyoneone know if i put 800mhz sticks in here will they run at 800mhz? with the new T9300 cpu?

thing is fast. loaded vista in like 17-18 minutes

 

I am wonder the same thing as well raydaddy. I upgraded mine to a T9300 and I am toying with the idea of picking up 4gb of DDR800........

 

Supposely, the intel chipset GM965/PM965 only support upto 667mhz/DDR2-667/PC2-5400. Thus adding DDR2-800 rams will underclock to 667mhz.

There were few guys who upgraded to DDR2-800 but hasn't confirm if it clocked higher or not.

Adding 2gb x 2 will be more efficifient then running 2gb + 1gb, even in Vista 32bit. Will just register as 3.25~3.5 gigs instead of 4gigs. Also will score higher in WEI. Even 1gb x 2 is more efficient then 2gb + 1gb.

 

CPU-Z is showing mine running at 667 (I have 4gb of 6400) so I'm assuming it is underclocking. If anyone figures out a way to overclock things besides the GPU let me know!

 

I do believe that the chipset itself cannot run the ram at anything faster than 667..it really is a physical limitation.

 

Hm... That's rather disappointing; I thought the Santa Rosa Penryns would allow DDR2 800...

It only makes sense too, since Montevina Penryns will be supporting DDR3, which already makes DDR2 800 obsolete...

 

Ya...I'm showing it has the Intel GM965 revision C0 chipset. I'll keep researching.

 

What is there to research? Gateway themselves say it is the PM; there is 0 reason to use the PM in this laptop. For the love of god though - will somebody just take off the heatsink again, and get a picture?

 

You may have to pay someone to do this.

1 - People in real excitement will forget about everything and install in hurry to see the outcome.

2 - No one is going to try to attempt to 'risk' removing the heatsink and apply $5 Arctic Silver 5 again. Just isn't efficient.

But if you paypal someone $2 perhap, they will do it

 

my 4-4-4-12 comes today results tonight.

 

Will be looking forward to your result.

Regarding OCing your CPU, you can use simple program that changes your FSB. I don't recommand this, so I won't post any links. But that is only way I see at the moment. Best ofcourse is through BIOS.

 

I understand But I am a hardcore Oc'r and can't raise the voltage on the cpu anyway so what's the harm. only thing stopping me now is that i do not know PLL of the chipset i believe. anyway put in 4-4-4-12 and worked fine. timings recognized memory bandwidth went from 4100 to 4600. 12% gain. will further bench and get back

 

Do we know what PLL the FX uses? Sorry if its old news, I have not been following lately.

BTW: T9300 CPUs should be in Canada any day now.

 

ROTFL, sorry I tried when updating the CPU, smeared numeric then M965

Hi!
After a few hours of gaming on my P-6831FX, my GPU temp goes up to 79c...
is there TIM puted on the 8800M GTS at this moment? If I put AS5 on it instead, what would that mean in temperature?

 

AS5 will theoreticly drop your temps by 3c-10c. The problem at the moment is getting at the GPU to apply the AS5. From everything I've seen posted in the forums, no one has been able to do it yet without a complete system tear down. The CPU is the only item that can be easily accessed and have AS5 applied to it.

 

I plan on buying one of these when BestBuy gets one in stock near me (all OOS now). There's nothing more satisfying than booting the laptop up to make sure everything works, then completely voiding the warranty and stripping it completely down to nothing to customize it.

Soon as I get it, I'll be doing a full teardown with pictures. I'd love to find a service manual first, but if not I'll wing it.

I already have a T7300, 4GB OCZ RAM, and 2 Hitachi 200GB 7K200 drives either laying around or in my Acer 5620 to swap in. Pity the Acer is only a couple months old, I wish I'd have gone for GPU right out of the gate instead of deciding I wanted more horsepower later. That's what the B/S/T forums are for, I guess!

 

Yea, PM965....was there ever a question...lol

 

X9000 runs at 2,8Ghz on default...how the hell does this run on 3,0Ghz?

 

In the bois , with the xl version that comes stock with the x9000 you can set the cpu to 3.0, google it and look for the reviews

 

XL comes with x7000 not x9000. You are right about bios unlocking the multiplier for the extreme cpus.

 

Opps, my mistake I wish x9000

 

Is it possible to set the speed of an Extreme CPU in the bios of a P-6831FX?

 

Yes, there is a setting in the oes I guess, you set it x1 or x2, I rememer seeing it when I googled the x7900

 

i got 3dmark to run for the first benchmark at 700/1100!! but it would not finish..left my window open for while and had more door closed as well as my fan on high, it was about 8C in my room I think lol.

The highest i can get mine stable it 600/945 and The temp never changes from stock temps.

 

How much are the temps on 600/945? Did zou use anything special including cooling? (For example notebook cooler pad, or AS5 on the GPU, etc)
On default clocks, my GPU temp is about 78c after few hours of gaming.

 

has never ever gone above 67C.

I just have it on my desk and I have a ceiling fan above it.

It idles at 44C-51C at 600/945 and tops out at 65C playing games.

Hit 67C on 3DMARK06 once.
