6970m into the Clevo W860CU/W870CU or Sager NP8690/NP8760

Compare what to what?

 

6970 vs 5870 in the same machine.

 

Hmm, I'll try. Not at the top of the to-do list but I'll put it on there

The difference is at least 20W, as I had a 140W reading for the HD6970.

 

so the 6970m wont be able to sustain stability at stock under 3d with out a 140 psu, are there custom 140w watt psus? or we're you just using a volt meter on default 120w to test it's current draw, also i seen you modified the heat sink, is this absolutely necessary or was that just an issue with a faulty card? i don't feel like cutting up a heatsink with a dremel =|


edit: can you confirm a w870cu 5870m heatsink would work on a 6970m with out any issues? i don't want to cut anything up, also if you could post some temps of it or give a quick heads up that the heatsink would fit with out having to mod anything.

 

Any updates on MSI GX660?

 

Has it been mentioned whether powerplay is functioning correctly on these cards?

 

The heatsink rework is mandatory for the GTX280/285 machines. Maybe not for the 5870 machines but Í can guarantee that untill someone tries this.

Power play works for the core but on the ES cards not for the mem. Should be fine for MP cards.

On my machine, the 120W works stable, but long term reliability can not be confirmed.

 

Just checked a W860CU HD5870 heatsink. Close, but no cigar.

Accidently, I have both W860 and W870 heatsinks available (from HD5870 and GTX285 machines). I can rework them for those purchasing a HD6970. Not for free, obviously.

 

Hey guys just to give you some information I found out while doing A LOT of research and questioning regarding putting the 6970m into the W860CU. The 5870m heatsink is close but it doesn't sit right on the core where it needs to. The MXM way to mount it using a 285m heatsink is good but you need to do some cutting. The other thing of course is psu, you will need to get the 180w to run it properly. In terms of running it at stock to even maybe a slight overclock you will need some small memory coolers all over the heatpipes and heatsink to keep it reasonable when gaming OR get a cooler with a powerful fan that sits right under your GPU fan and feeds cool air at all times or you will overheat it after a couple hours. I just wanted to put my input since I was really considering this after my 280m went of me and have to buy a new card. I opted to go with the 470m since its plug and play and no modding needed. Can be overclocked like CRAZY, just check the 470m overclock pages, runs at good temps and get very impressive scores, near 15000 vantage score.

EDIT:
Forgot to add the reason why it get very hot is not all because the heatsink on the NP8150 is better with a memory cooling pipeline, that has very little to do with it, same with space in the notebook, both laptops have about the same space for the GPU. The issue lies in the drivers since the W860CU officially does not support the 6970m or the 485m and therefore the software does not know how to run them efficiently. Someone has to release some modded drivers to support both of these GPUs (and future ones as long as they are 3.0 compatible) and they should run on our comps with some heatsink modding just as good as they run on there respective machines.

 

so has anyone here make NP 8690 workable with 6970m yet? i'm interested in the work and the result as well. Don't let this thread going down yet.....

 

gearofware: Check the np8690 owners lounge a couple of pages back. Forummember kingkong9 has installed this gpus. No new heatsink or bios needed.

Now that we know the 6970m works in the w860cu/np8690 what do you guys hink about the new 6990m? It offers great performance, but there could be a power problem I guess.

 

I'm not sure if the vbios supports it, but the 6990m is the same 100w TDP as the 6970m for what it's worth.

 

But is the 6970m in fact a 100w card? I thought it was a bit lower than the 485m.

 

6970m is rated at between 75-100w. 6990m is solidly 100w.

Get a 180w adapter and you're fine on power. The card is so similar to the 6970, it should still work as far a vbios (I think the 6970 uses the vbios for the np8150).

If you have a 5870m, you can use the heatsink since the two have the same physical layout.

I plan to do this once a reseller has one to sell. I'll write a how-to for giggles as well.

 

My concern is that if the 6990m is 100w, the w860cu wont be able to run it. The 485m was tested in a w860cu but it would oly boot with just one memory stick (2gb) installed.

 

That is an excellent point... Dang it. Was that test with the stock 120w ac/dc adapter or a 180w version?

Edit: On second thought, I'm not even sure it's worth the head-ache if that's the case. 6970s are still floating around, so I might grab one of those with a manageable 75w TDP.

 

It was tested with a 180w psu. Also, the poster mentions the 480m working in this machine. What us the tdp for the 480m?

Here is the original post:

http://forum.notebookreview.com/sag...le-2gb-ram-succeed-other-ram-size-failed.html

 

Notebookcheck says the 480m and 485 both have a tdp of 100w. But that is more of a class of cards (ie: big, hot, energy intensive) than an exact power draw. Especially because the 480 must be using less power with less shaders and a lower frequency.

I would err on the side of optimism and argue that his results were due to an incompatible vbios, but the ram thing... That makes me think it's more of a power issue.

So... whether the 6990 consumes less than a 485 might be the deal breaker. Of course, it would need to consume A LOT less to do more than booting.

 

I've done the change from gtx280m to hd6970m in my Clevo W860CU.

Everything works pretty nice for now. GPU Temp in idle: around 60 degrees and under load around 88 degrees

No blackscreens (ok it once apeared in heaven dx11) or shutdowns under normal gaming load. Tested so far with the witcher 2, LOTRO and AoC.

Atm im searching for a new heatsink. Does anyone know where i can get one for the hd6970m? I found this on ebay ( ATI HD5870 video card Heatsink Kit for the W860CU | eBay) but it doesn't look like the stock hd5870m heatsink....

greetings

Frickeladmin from Germany

 

Congrats on the successful upgrade!

60C in idle is pretty hot. Might want to hurry along on getting the 5870 heatsink. There is no w860cu heatsink for the 6970, but the 5870 is supposed to be a perfect fit. My 6970 should arrive on monday, so I will know more then.

The 5870's heatsink looks like this: . (Though I have removed the sticker).

 

Actually, if you have the new revision of the 280M heatsink (6-31-W860N-023), then it's exactly the same heatsink that is shipped with the 5870M, so no need to buy a new heatsink.

 

60C is pretty hot? My old GTX280M was in idle at 54C...i think that 6 degrees more is ok for the new card. But im not an expert for notebook hardware.

I've orderd the heatsink from my eBay link and found out that the seller is Eurocom^^
Hope that the new heatsink is doing there job a little bit better then my modded one. In order to fit the heatsink, i've followed the guide on mxm-upgrade.com ( http://www.mxm-upgrade.com/W870.html).

Till now i dont get any blackscreens, shutdowns or artifacts while gaming.

 

Ok, just got my first blackscreen. Crysis 2 did the job. It has quit at 87 degrees GPU, 190 degrees memory temp.....

I hope the new thermalpads and Heatsink can solve such problems

 

what is your actual heatsink part number?

 

Ok i got great news for everyone ho's planning to upgrade.

I've buyed a new heatsink for the HD5870M from Eurocom eBay shop. I've asked the seller if it fits for the HD6970M because the pic in the auction looked not like the stock heatsink.
So he said that he's doing a custom mod for the W860CU to fit the HD6970M perfectly.
I've paid 28 $ + international shipping. So i've you plan to upgrade to HD6970M, ask Eurocom if they can do a custom heatsink for you.

Greetings.

Frickeladmin

 

where can i find the part number? But its the stock heatpipe from the 2009 W860CU with GTX280M inside.

 

You will find it in a sticker on the heatsink. The thing is the there is 2 heatsinks for the W860CU: 6-31-W860N-022 is the old one and not too much efficient. 6-31-W860N-023 is the new one and it's what you will receive from Eurocom. If you already have the new one then I'm sorry to tell you that the heatsink that you bought will not help you too much even modified. But if you have the old one then you will definitively be beneficiary from that heatsink upgrade.

 

Thanks for the info. I've just opened my notebook again and found out that its the old one (6-31-W860N-022).
Looking forward to receive my 17W/mK Thermalpads and the new heatsink.

Heatproblems should then be under control.

 

I could see myself upgrading to the 6970 sometime down the road. I've got a 5870, so no worries there. But would I need to do something about the BIOS or vBIOS?

 

According to the discussion here, you only need the new heatsink :
http://forum.notebookreview.com/com...970m-brand-new-free-heatsink.html#post7583483

 

Actually, I just recieved my 6970m, and (at least this version of the card) is not quite fully compatible with the 5870 heatsink. The bottom right has a lone capacitor that sits at least a millimeter too high and is not in one of the raised areas. I think I can shave the heatsink down sufficiently to compensate, but this may contribute to others' higher temps.

I plan to toss up a new thread with pictures and all the steps for my install, just might take a while longer than I had hoped.

 

Does your 6790M card is a Clevo one ?

 

Hope so. Part number 288-1e188-000eu.

 

this doesn't seem to me a Clevo part number. Do you have any stickers on it?

 

That number and :a110800101885. Sorry, typing this into phone, as the laptop is disassembled. Bought from eurocom, board is blue, with those soldered mount points, told them it was to be put in a clevo w860cu.

 

No, Clevo's are green and part number is 6-77-X720L-D02

 

Well, let us hope it is compatible then.

 

It should be compatible but the Clevo heatsink will not fit perfectly.

 

Yeah, that's a fact, but it appears that the only problem is one chip at the bottom with a + sign. Thank goodness for rotary tools.

 

@ll
sorry guys for long come back. Just too busy from work..

Heres some photos STOCK 3dmark11 and vantage scores:

 

I'm a little bit jealous about your temps.

Witch heatsink do you use?

 

I used heatsink from my old GTX 280m.. No modification done, i just put thermal pads all rams surround DIE.
sometimes idling at 43(my lowest)

Whats your idle temp??

 

can you give us a pic? because it seems that i have to do the same modification for my heatsink...

 

Then you must have the new revision of the heatsink. my idle temp (with my old gtx280m) was at 54 degrees and with the 6970m at 60 degrees

 

Here is a pic of the modifications i have done to fit the heatsink for the card.

Sry, doublepost

 

No! my w860cu is the first revision release (yr 2009 w/o usb 3.0). Check if heatsink properly in contact with 6970m die. Be sure all ram chips have thermal pads. Heatsink must have little pressure on die and used better TIM. I used shin-etsu at the moment.

 

currently i am using office PC. ill send photos when i got home. Perfect Mod!! For that modification it should be lower than mine??.. are you sure HS properly contact with dye??

 

Im sure that there is enough contact. for now im very confused....especially because the temperatures of my GTX280M were higher then your 6970 temps.

Here is a screenshot of my HWINFO32

can you check the fan speed? what % when idling?? I modified vbios of mine thats why i got a liitle lower temp.
From 20%@50C to 30%@45C -----------100%@100C to 100%@70C
