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

Copper or aluminum? My fin is 0.9mm and it's perfect. How many degrees you get under load? What thermal paste did you used?

 

I ordered it there on Thursday the 16th and I have not recieved it yet, so that's why I was wondering when you placed the order?

 

I ordered mine on the 16th of last month also and I haven't gotten mine yet either. They emailed me to let me know that it was sent my way on the 3rd of August and that it should take between 7 and 12 days to get here. That has to be the longest I've ever waited for something I've ordered online. Needless to say, I'm really itchin' to get this thing already.

 

Meaker why you ordered a HD 4650 DDR2. I mean your 9600M GT performs the same or even a little better. Some Ocing expectations maybe ???

 

Originally it was for my 5520g which the power connector gave out on me (the 9600m was not fully compatable and I thougt the 4650 was worth a shot). So yes Ill try them both and see and keep the best one.

I've not even had the email about them recieving it yet. If it takes much longer i'll demand a refund for unreasonable waits.

 

Just got my 4650. Installation went fine. I used the thermal pads I found with the crazy 50W/mk rating. I cut them up for the gpu and also replaced the old pads on the memory modules. I was a little worried because they are only 0.5 mm thick and thought that the pad I put on the gpu might not be thick enough given everything I've read in this forum about a 1 mm or greater gap being present. Here are my results with no overclocking and using Catalyst 9.7 drivers (used mobility modder on the standard desktop driver package - control center works fine):
5244 in 3d Mark 06 idling temp is 49 degrees under load it seems to top out at 69 degrees.
My stock 8600m gs gave me a humble 2730 3d Mark 06 score and my idle temps used to be around 65 degrees and flaming up to about 82 degrees under load with Arctic Silver 5.
I'm guessing the thermal pads are doing their job and that the gap is adequately filled. Needless to say, I'm pretty happy.
I had to find another piece of temp monitoring software because speedfan doesn't seem to recognize the new gpu. I used GPU-z. Do you guys recommend any other good gpu temp monitors?

 

HOW MUCH CAN I PAY YOU FOR ONE OF THOSE PADS? (If you have any extra..)

 

Added another mod of sorts. Found an interesting heat sink like pad with its own adhesive designed to suck heat away from IC chips. I cut it in half which was a little tough cuz it's made of a thin sheet of aluminum with a coat of shellac (shellac alpha - whatever that is) that leave it really cool to the touch and applied each half to the memory chips on the back side of the video card. Those chips seem identical to the ones that need thermal pads to interface with the heatsink so I wondered why not have some sort of heatsink on them too. Each half covers two of the chips and it dropped my idle temps by another degree so I'm sitting at about 48 degrees idle temps now. It's not much but I guess it can't hurt. Here's a snippet of the temps:

 

Congratulations, nice load temps.

I played around with overclocking on this card and it's just incredible, I have it stable at 650/600! It now handles Street Fighter 4 at the laptops native resolution @60 fps with some minnor tweaks. It's just jaw droppingly gorgeous!

Ordered 16th July, lol all 3 of us ordered it same date...

 

For Bubble gum lolipop unicorn sake mine has not even arrived at the shop yet

Again Sewje when did you place your order exactly?

Pic of my lappy btw, its waiting to make the HD 4650 scream for mercy.

 

I'm propably going to order one next month

 

Wolfman, you should download OCCT and run the test for 15 minutes. That will give you a higher temp reading than you will ever get in game. (10-15C higher). Its the best way to stress test your GPU and its cooling solution.

 

Running OCCT CPU stress and furmark at the same time will test your system more

I find that EvE and OCCT CPU test is actually VERY punishing (using a wall power meter to measure what combination uses the most power).

 

Im talking about OCCT GPU test. Futuremark is a joke compared to it.

 

I found this, but I haven't read it yet, it's about volt modding I was just playing with my vBIOS (again ) and saw the "voltage registers" tab in RBE, clicked help and this is the link from there

 

Well, after using 0CCT and Futuremark, both for about an hour each, I got up to 84 degrees on Futuremark and 95 degrees on OCCT. Mind you that's with an overclock too - 650/550 and no undervolt. My 3dMark06 scored 5541 with the new clock speeds. My idle temps tend to hover around 45 to 49 degrees. Don't know what the temps really mean given that while gaming, I haven't cracked 76 degrees but I haven't really had much of a chance to put it through its paces yet.
What have you guys been using for overclocking and undervolting this card?
I attempted modifying the vbios and after an apparently successful bios flash, the catalyst drivers no longer recognized the card following the reboot even after uninstalling and reinstalling them so I had to reflash the old bios back onto the card.

 

Nonono, FURMARK not futuremark. Yeah if you take the voltages out of a set range the drivers wont recognise the card, how nice of them eh?

 

I don't think this will work with the 4650 since I believe the VIDs are hardwired into the card.

 

Well, bumped up to 650/600. System seems stable. Ran 3dMark06 and got 5781 points. The highest temp after running it twice was 85 degrees. Ran Furmark for 20 minutes and Meaker was right, it scorched up to 101 degrees but that seemed to be the peak halfway through the 20 minutes. Thanks for the tip about the Voltages Meaker but I'm not sure what you mean. I kept the voltages within the range provided just dropped the high by 0.1v. Or should I try to keep all three within a set at the same voltage?
Classic, exactly which settings did you change in your bios to accomplish your successful cooler undervolt?

 

101 degres what the hell...Yeah undervolting seems necessary. So you got only 500 points more with your OCing at 1280*800 ????

 

I've read them all and yes, I don't think that we have the right hardware (volterra VT11XX IC chip in there) for doing it I guess there is no fine tuning for us.

 

Yup, I got a performance increase of exactly 537 points in 3dMark06 by increasing the clock speeds from 550/500 to 650/600 at 1280x800. I'm sure that the thermal pad I got is definitely doing about as good a job as anything else could, giving me a temperature range from 45 degrees at idle to 101 degrees under the most stress I could possibly throw at it while overclocked. So the only solution I think is to undervolt, or drop my clock speeds down a few notches. I still have yet to see it go beyond 76 degrees while gaming but that 101 did worry me a tad and even the 85 degrees I hit while running 3dMark made me rethink my clock speeds. What do you guys think? Is 537 points a worthwhile increase in terms of performance?

 

I don't get why everybdoy freaks out about FURMARK and OCCT temps.

YOU WILL NEVER REACH THAT GAMING...EVER!!

In OCCT I hit 102. I'm really not concerned. Especially because the vBIOS that comes with the 4650 doesn't even throttle the fan to 100% until 100C (see pic)!

(thats one of the things I changed in my vBIOS)

Instead of telling you what I did, would you rather just take my vBIOS? Its fan speed scales up to 100% @ 90C, (instead of 100C), and works on 1V during performance 3D (instead of 1.1V). If you undervolt lower than this you blackscreen, So I think my vBIOS is as good as it gets. Everything was done in RBE.

Fan settings: default and new

Here is my edited vBIOS:

PS: WOW I love megaupload! It is BY FAR the fastest and best filehosting (no countdown, 1 Mb D/L speeds..)

 

Thanks Classic, I'll give your VBIOS a go ! I just retried 3dmark06 and it spit out 5857 this time - I just disabled autoprotect on symantec and shut down skype. So a performance increase of 613 points in total now and the temp peaked at 82 degrees during the benchmark.

 

With my 9600M GT@0,89V@600/1500/900 i reach only 71°C on gpu during a 3dmarks bench. So 85°C seems high to me now, that's all. But if you say that the 4650 can handle 100°C...

I'll give furmark and occt a try.

 

Also noticing a huge increase in battery life, tho I need a new one now since the existing one is nearly knackered.

Used to report 1h on a full charge on the nVidia card, now I'm getting an extra 30 min on top.
Brand new ofcourse it used to do 4h, so posibly an extra 1-2 hours on top at least? Can't wait to see when I eventually get a new battery.

 

Kallogan, I'm interested to see what you'll get in OCCT...run it for 15 mins and report your temps.

 

i can get to 90c while playing l4d, max temp i got on furmark is like 87.
edit: extreme burning mode as well.

 

Well, seems like an undervolt isn't feasible at 650/600. It blackscreened after about 3 minutes into 3DMark06. So I guess there just isn't enough juice for that much of an overclock.
Sewje, did you undervolt your 4650?

 

As you can see only 71°C after 30 minutes with OCing (600/1500/900).
I'm not the only one, in the 5930G thread we all undervolted our 9600M GT successfully at 0,89V. The max possible OCing at this voltage is 620/1550/900.

With my crappy and hot T5800 and the stock voltage voltage on gpu (1,05V), i used to get 90°C in very demanding games. That was too hot. I lost about 20°C by undervolting the gpu and changing the processor. It changed my life ;-). I can play 3 hours on a roll without even reaching 80°C.

 

No I had to overvolt to 1.2 for that mode. because of crashing even at default voltage, but it's stable with the overvolt so I'm keeping it. Since I overvolted the GPU I went an undervolted my CPU by 0.250 so overal 0.15 system undervolt is great for me, and temps are still lower because the CPU no longer goes up too high, upto 90c tops I've seen it. now i rarely reaches 70-80 depending on the room temps.

Could probably push it higher but I'm fine with the rounded numbers.

 

Thats really impressive dude. I wish the 4650 would run on .9V. I've tried it, it blackscreens. The next lowest is 1V, which is what I run mine at. I really wish this card could support custom voltages..I bet 9.5 would cut a solid 10C off my temp.

 

Yeah our cooling system are pretty weak and cut 0,1V off the gpu or more plus cpu undervolting can change everything. I remember when playing Mass effect sometimes i reached 93°C after 30 minutes. Now it's past.

I don't understand why manufacturers put the gpu at 1,05V while it works great on 1V or even 0,89V. I can't apply custom voltages either. My choices are 0,89V, 1V, 1,05V, 1,16V. With only 1V, i succeded in scoring 7300 points with 700/1750/850. As you can see, there is a huge margin.

My idea is that they put those high stock voltages to allow the customer to play with OCing don't know really...or they hope the lap will fry after the warranty ends up ;-)

 

Wow......1.05v?

The GTX 260M in Asus G51s can run fine stock clocks with no problems at 0.90v (0.95v stock) and that GPU should require so much more voltage....

 

Yeah but the GTX 260M has a 75 watts TDP while mine has only a 23 watts TDP (in theory). So i guess the amperage is much lower on mine.

 

My card is still not in, I have said if it's not in by the end of the week I want a refund.

 

Then why wont the 4650 work on .9V?!?!

Man I wish it did.

 

Because its design is totally different.

 

Most definitely a plausible possibility in order to gauge the potential money from customers and blame the problem on them.
Then again, as with CPU's it's also possible they choose high enough voltage that would be stable across various range of notebooks (even 2 identical notebooks might have different stable lower voltages)... so I suppose they set it to a certain standard like the cpu's.

Although it would be good if they spent some time testing various voltages automatically for each unit they put out (they'd pretty much need 10 to 15 mins of testing for each unit to know if it's stable or not).

 

The 9600m GT is a 65 nm card. It transistors should require MORE power than the 4650 (55nm). The RAM is DDR2 (DDR3 takes more) so thats not the problem. So I'm really am having a hard time understanding. I guess there's more in the mix than that though.

Edit: The default core speed is higher on the 4650...thats the only thing that is not in its favour.

2nd Edit: Also the 4650 has 514mil transitors compared to the 314mil on the 9600. Thats a lot more resistance.

 

Mine also didn´t arrive nor did i recieve mail. I ordered July 20th.

 

Yeah but if the current draw is lower the power can still be the same.

Also:
4650 = 514 million transistors
9500GT (desktop = notebook 9600m) = 314 million transistors

Therefore there are going to be more defective 4650 cores, you can increase the yields by increasing the default voltage so more cores pass.

 

makes sense.

 

I figured another way to improve cooling of my 5920g.

I noticed that the gpu heatsink has a huge gap between itself and the exhaust openings.
I cut and bend a credit card that it fits between heatsink and openings. I attached it to heatsink and chassis with tape.
It´s not very professional but improved my cooling a lot.
Before modification furmark peaked to 97°C at 1500secs now it runs all way up to 3700 secs until reaching 97°C.
Ambient temp was 20°C btw.
It seems like there is a stronger airflow out of side openings now.

I will try to so the same to the cpu heatsink gap altough it is a lot smaller and will not likely improve cooling that much.

 

Oh yeah this a proffesional outfit for sure. They don't even have my card yet after over 4 weeks so does my government have to do with it before they are even sending it to me.

 

They still haven't recieved the card from Acer?

 

Apparantly not, and I don't want to have to dance with Acer again, I won't.

(they played me around a few years ago and took 10 weeks to replace a DOA laptop offering me an INFERIOR laptop (I mean seriously, it was a P4 laptop instead of a Centrino and weighed 4.5kg instead of 3.0kg))

 

I'm really sorry to hear that, Meaker

Pics

 

Here are some pics, i was too lazy to disassemble the whole construction but i think you can see enough.
I also added some memory heatsinks.
