My 5920g...WITH A HD 4650! (need help)

Thanks, I'll try it I have yet to order some heat-sinks for the RAM, I don't know why I delayed it sooo long, they are pretty cheap

 

You´re welcome

Btw. i had to cut them a bit down to fit between chips and caselid. Before that the lid did not close anymore.

 

The hyperX looks pretty snazzy btw:

Do you have a temperature probe? I tend to see that heatsinks actually make the memory run hotter since most aren't applied well and thus trap heat.

 

Yeah, I thought something like that

It does, but I have plenty of problems with their memory cads and thumb drives, that's why I choose Patriot

Not at all, but cooler is better you know

 

I know cooler is better but what I said is that from my experience, memory heatsinks in notebooks tend to be hotter than memory without them because heatsinks can trap heat.

 

I got your point, but stability aside, how can I check is there a difference in the temps?

 

You need a temperature probe (IR thermometer). Unfortunately the memory has no thermistors for your system to read.

 

mhh i´ve not thought of that. I´ve got an ir-thermometer at work, will check it tomorrow.

Yep, they do, but i´m mainly interested in performance. And in that sector they perform very well.

 

Going from 7-7-7-18 to 5-5-4-12 (and dropping some others) added around 5% to my CPU score in 3dmark 06.

 

wow nice
memtest86 stable ?

 

Can somebody play crysis warhead on windowed screen 1 hour then see how much Gpu temp gets hot max. ? I've seen max. 118 degrees without cooler with my 4650 on 5920g then decided to put it back on my 6930g. 105 degrees without the back cover 105 degrees with cooler.

 

What clock speeds/resolution/and detail level are you running? Haven't played warhead yet but while playing crysis overclocked to 650/550 on the 4650, I got up to 92 degrees (which was the hottest temp I've ever gotten while gaming) with everything on high at 1280x800 after playing for about an hour in fullscreen mode.
118 is pretty high though, what are you using to interface with the heatsink?

 

You NEED to undervolt that card. 118 is WAY too hot. I posted my undervolted BIOS earlier in this thread, feel free to flash it onto your GPU.

 

How the heck is the GPU not automatically underclocking if you've seen 118C?

 

5920G is like that, it can burn into your hands, but you can still play at maximum performance

Congrats, Nm1, you beat my record with 8ºC (mine was just a test run though, I'm not that crazy to play at those temps)

 

118°C ... your card will be short lived.


I measured the temperature difference between memorychips with and without heatsinks. sgogeta4 was right , they do trap heat.

I used folding@home´s memtestG80 tool to produce a lot of heat on the memorychips. Clocks were, Gpu: 475mhz Memory: 494mhz
Measurepoint was exactly the same with and without heatsink: outer right corner of the chip.

Ambient temperature: 26,5°C
Gpu temperature during testing: 80 - 82°C

Memorychip with heatsink: 43,5 - 44°C
Memorychip without heatsink: 42 - 42,5°C
Heatsink itself: 48 - 49C°

I removed all heatsinks now, hopefully this will give me another few degrees improvement over my previous test.

*****************EDIT*******************

I just ran a couple tests with furmark. With and without heatsinks. Seems like they actually DO improve cooling if there is enough airflow, in a closed case for example. Without heatsinks furmark peaks 97°C at 580secs and with heatsinks at 740secs. Also does the temperature decrease more fast with heatsinks after closing furmark. Ambient temp is 26.6°C. btw. the new furmark version is giving higher temps than the previous v. 1.50 i used before.

 

Got my 4650 today. So far highest temp in furmark was 93°C at 800secs.
Idle is 49-50°C. Card is on stock clocks.

 

Does this "heatsink traps heat" apply to the memory chips on the video card as well? Let's say you are using a customized/modded heatsink for the video card, would it be better to leave the ram chips without a copper heatsink?

 

hm no i dont think so, see ---> EDIT : i made a couple of tests and somehow they do improve heat dissapation when high airflow is applied but they do trap heat when there is no or little airflow,for example when idle.

 

I can´t overclock my 4650 .. atitool isnt applying any changes.
How did you guys do it ?

 

okay i found a better tool than atitool, gputool. All those TOOLS
managed to overclock my card to 710/600. Got 6168 3Dmarks. Stock Voltage. Max temp in 3Dmark06 78°C.

Max temp in furmark is 105°C at 400secs though.

 

Right well mine has now shipped apparantly, no email or anything. So we will se how it handles in my notebook.

Are your guys modules double sided mem? My GDDR3 9600m is not but by the looks of it yours are, my notebook came with a backplate/heatsink combo that I should be able to fit to the 4650m and cool the rear chips (my gfx chip is as they are traditionally, facing up).

 

Mine was double sided... unfortunately my card stopped working. All of sudden pixelated and bluescreen, at stock clocks though. Now even the startup Acer Logo is pixelated. I´ve send it to RMA today. Hopefully this wont take so long as the first shipment.

 

owwwwwwwch.

That sux.

 

Wow, that really does suck dude. Were you gaming at the time? Did you ever overclock it more than that 710/600 you mentioned earlier? I thought that those clocks might be too high. I haven't gone beyond the 650/600 though I'm worried about even what those speeds are doing to the card.

 

It does indeed.

No i have not gone further up and 710/600 was just for testing purposes. It ran only 5mins at those clocks. I think it must be something else. I was playing anno 1404 when it happened, at stock clocks.

 

that is what happens when u use a card in a laptop which is not supposed to hold the card.....

 

I wonder what would you say if it was Sager or Alienware, with upgraded GPU and same troubles...

My condolences, Nuke.

 

I got mine today, the back is more crowded so the original backplate does not fit, oh well. I'm at work on my break atm so I wont be able to install or test it untill later.

 

No, thats not what happens. Mines been running fine..for longer...why don't you just stay out of things if you dont understand them? There's no secret "OMGHAXD L33t chip" that this laptop lacks that makes it incompatible with the 4650.

"That is what happens..." as if you have any idea...

If you know of some ACTUAL legitimate reason that this upgrade is faulty or likely to fail after time, please share it with us.

@ MEAKER:

What do you mean "too crowded"? it won't fit? I don't understand.

 

I guess you pushed it pass breaking point, a hard lesson to learn and a reminder that just because it is an amazing card they still have there limits.
I would never have pushed the GPU clock past 675 since thats the speed of the 4670, if it could have handled it, it would have been called the 4670.

Lets hope it was just a bad apple.

 

Congrats, Meaker. How comes that there is no enough space? Don't you have space between your 9600M and the back-plate?! Mine has at least 0.5cm space between the memory and the back-plate.

 

Maybe. But i´ve never ever seen a card doing such things after overclocking it too much. All Cards, notebook and desktop, i´ve overlocked so far never died on me this way, even the ones i hardmoded to get more voltage. It seems to be more like a short-circuit like behaviour, although i can´t imagine how. I have assembled and disassembled my 8600m GT so often i can´t count it any more. But it never had any issues, and overclocking was also very high.

I hope so too.

 

It has a lot of surface mount componants on the back and the back plate uses a larger mounting area so it cant sit flat to the PCB and does not make contact with the PCB so I will use the smaller one on my current card so the rear memory wont have heatsinks, not that the plate does much.

 

Wow 58C max temp at load at stock running 06.

 

Wow indeed.

 

How are you guys overclocking this card?

 

I can't rationally believe that

 

I managed to get the rear heatsink on:

So when I change the clock settings GPU-z first window shows the new clock speed but with powerplay enabled or disabled in 3d or 2d it does not show the new clocks in the real time clock speed window, only my stock clocks which is odd since I don't have a profile with stock clocks anymore.

 

So I downloaded the modified bios here for voltage and tried changing the clocks on that one profile (keeping the voltage at stock) and it will still only stay at stock clocks....

 

Where can i order this card!! omg! I can't find it..

Can anyone help me find one? I REALLY need it!

 

We got it from ipc-computer.de

The results are IN!

Stock clocks I managed to score 4972 points, max temps were around 58C running the benchmark.

Overclocked I reached 6081, that was achieved at 680/626, max temps were around the low 60C mark. The heatsink is very well designed in this machine obviously.

Btw I tried notching the voltage up 1.2v and the core clocks were testing stable at 750Mhz! Then the machine shut off So I think i'll leave it at 1.1v, still nice clocks and the memory managed a healthy 25.2% OC which is not bad for already high clocked DDR2.

Do I keep it? I think so, yes I have lost points (more on that in a bit) but it runs SO much cooler.

So have I really lost points? I am going to try vantage next!

 

It looks like it has been removed from ipc-computer site or notebook-doctor site
They still sell the 4670 though. Unfortunately Acer is not making the 4670 card in MXM type II form but in MXM 3
You can try at this shop
Acer Parts
But the price they give is £9,487 which is insane so I think it's better if you email them and ask them for a price. Generally this site is more expensive so don't expect the same price as the notebook-doctor. I would say £100 more.

 

why was it removed?

 

Probably Acer told them so.

 

VG.M9606.005 and VG.M9606.006 are still on their site they are just now non-special order items and are slightly more expensive.

Put the codes in the search box to find them.

 

(GPU scores)
Vantage GPU OCed 9600m = 2005
Vantage GPU OCed 4650m = 2262

So in vantage its 15.5% faster than the 9600m.

 

OK, I was inspired by Meaker! So I went out and got some new thermal interface material for my cpu hoping that in turn it will help bring down my gpu temps. I got a liquid metal pad and replaced the arctic silver I then cranked up the clocks to 680/625. I got a score of 6039 in 3dMark06!! Cracked the 6000 mark on a 5920g!!! The temps still took a huge hit though as I peaked at exactly 90 degrees. It hit that ceiling twice over the course of the run but the fan kicked in to full blast thanks to classic77's modified bios and dropped the temp back down 3 or 4 degrees. I don't know that I want to try furmark at these clocks as I can just imagine how high the temps will go but on the plus side my T9500 CPU now runs a good 10 degrees cooler on average. Went from idling at 45-47 degrees to 35-37 degrees on average. If only the gap between the gpu and heatsink wasn't that wide, I would totally throw in one of those liquid metal sheets. I think I'll try that credit card mod mentioned earlier and see how it affects the temps.
Update:
So just ran furmark and at these new clocks, I peaked at 101 degrees after 500 seconds and it didn't go beyond that for 100 seconds after so it's actually running cooler now than it was at 650/600. Though it ran hotter under 3dMark06 - go figure! Looks like having a slightly cooler cpu definately helps. I guess I'm keeping the new clock speeds!
