7970m in a M15x....Why yes

I can see that some of you got the 240W adapter (from the M17xR3 right?)

Has anyone ever tested the M17xR2 240W psu on the M15x ? Need some input about it

@ King of Interns and Mexic00ls
Do you manage to overclock both XM and 6990m for gaming with your PSU ? If that's the case, what are your stable settings for demanding games?

 

I'm using the R2 240W psu, regarding overclocking gpu and cpu at the same time, you'll need to find the sweet spot for each application. E.g. for BF3 forget about OCing the cpu when using a 6900m series card, in fact forget raising the gpu clocks as well.

As I already explained a couple of times, the gpu voltage supply circuits on the mobo are not designed for such high end cards.
Funnily the CPU can get cranked up to insane levels (30x and more) without issues (except for the voltage drop on the gpu)

 

@svl7

PSU M17XR2 No problem M15X

PSU Delta ? or psu Flextronics ?

 

I have the slim Delta 240w psu, i dont overclock the gpu while playing games as i can pretty much play bf3 on high setting at good fps, i only oc the cpu while encoding. But now 90% of my time is on the Aurora, i have only oc both the cpu and gpu while benching.

 

Slim Flextronics 240W here.
No issues (just disable the POST warning in the BIOS), but also no real gain. The only few times I really needed this PSU was for hardcore overclocking on the CPU, for everything else the standard PSU worked perfectly fine.

 

Thanks guys

 

M15x and M17xR2 are both Flextronics, either Delta or Flextronics 240 watt PSU should work.

 

guys, Is the GTX260M heatsink compatible with the ATI HD7970M ?

Gentleman,

Currently running with 920xm and 560m in the m15x. When 7970m becomes more easily obtainable, is it a simple plug-and-play card? Unlike the 560m you had to mess with modded drivers, is there anything else special about putting the 7970m in? I heard some people were experiencing significant issues with the card and this particular type of CPU (throttling, voltage). Thanks in advance.

 

As explained to me from another thread, only the X plate needs to change. The heatsink should still work from your 260M.

 

Hello

Thk

 

I don't OC the 6990M cause the temps are already high enough, plus like Mexic001s stated BF3 runs on max settings at stock clocks.

I did however play the game with the CPU OCed to 25/25/23/23 which really helped fps. The 6990M never throttled even under high load for hours, while the CPU was pushed to nearly 90% load at some point according to core temp running in the backround.

I personally am not sure if every M15x board has the voltage drop problem most experience. If I had the cooling I am pretty certain I could happily OC the GPU in games too and have no problems with throttling.

I have run furmark and prime 95 simultaneously before with high CPU OC and GPU OC and the gpu didn't throttle then either...also I ran folding at home on CPU OCed and tested with furmark at GPU OC: again no throttling.

No question therefore that the CPU OCed at load simply has no effect on my GPU's voltage in my machine. Maybe I am one of the very few lucky ones!!!

 

Hello

Spoiler

First test

Guys I might need your help with a very strange issue in my M15x with the 7970M. After upgraded it, everything was fine till I noticed that I was losing the display everytime I touched the keyboard, touchpad, sensor, basically all the laptop areas I can lay my hand on...when I then re-touch the laptop, the display gets back - this is a real random issue, sometimes it happens even when I don't touch anything...funny enough it happens only with the 7970M, I put back my 6970M and everything was fine...
Anyone ever heard or experienced this issue ?
Cheers guys

 

i would say it is a power issues the combo of your 940xm and 7970m might be too much to handle for the m15x. but we cant say for sure as you are pretty much the lone test monkey here. this is one of the reasons i decide not to go with the 7970m and will rather wait for the release of the 7950m for the m15x

 

Firstly have you installed drivers for it yet? The above screenshot shows you haven't. Without doing that first of course your card isn't fully stable. Besides it is important so that you can monitor your temps. Maybe it is overheating and you wouldn't know.

GPU score is looking fine, but your physics score is low for a 940xm:

 

Hi svl7, it's me again...how exactly u can get a physical score @7330 with 920xm?!
I must say it's a miracle man, absolutely unbelievable. is it contributed by ur hard modification of 920xm which u posted in T|I?

could u share ur set of 920xm : )

Preset TS ?

 

Hahaha, simple - crank up the multi guys!

No voltage mod applied, else the score would be significantly higher, but I'd loose my GPU performance.

 

Where are people obtaining these from? I rang Dell and was told that they are unavailable unless purchasing as part of a new laptop.

 

Will the m17x r3 heatsink work with this card inside an m15x? Also will the standard PSU be enough. This looks a fanastic card but I'd rather use my old 5850m than have an unstable laptop.

 

The 7970M uses only fractionally more power than the 5850M. The upcoming 7950M will use less power than the 5850M while still performing alot better than even the 6990M!

If you really are worried hold onto the 5850M and get the 7950M when it releases. Or get the 7970M and undervolt it at stock clocks and voila it will use no more power than your current 5850M (perhaps even a tad less!)

Interesting. Thanks for that. It sounds like an amazing little card for sure. Makes me want to purchase one.

 

Indeedy! The price is a little steep however you will benefit hugely from this upgrade considering the 5850 is now 2 generations old. This card steps up from the 6000M series very well in both performance and power efficiency the 5850M is basically mid range in comparison lol!

 

Not much info has come out on the 7950m, but the m15x is designed for a gpu tdp of 35-65. The 5850m was a 40w card so is well with in the range, the 7970m (per dell) operates at 100w, while the 6990m is a 75w card. Im hoping the the 7950m rates at about 55-65 and that it will also preform better than the 6990m. That will be about perfect for the m15x

 

100w card? I always thought the M15x PSU capacity wasn't much higher than that!

 

The psu is 150w, the 7970m will work as some users have proven, just dont expect it to run flawless on the m15x

 

do yuo think it would run better with a high powered dual core like the 620m instead of an extreme quad?

 

Extreme quad all the way. The i7 620M will be a major bottleneck!

Also yes the 7970M has official TDP of 100W like the 6990M HOWEVER in tests done by many on here the 7970M runs MUCH MUCH cooler even at an overclock.

SLV 7 a M15x user here runs his 7970M and gets 40C idle temps in 22C ambient and the card maxes around 70C! The official TDP of 100W therefore is very misleading this card is closer to power consumption of the 5850/70M than the 6990M.

Also you can use the DELL 240W PSU too. It works flawlessly

I shall be joining in with the 7970M fun very soon! Card purchased!! It is a Dell QS card with blue PCB so will be interesting to see how well it works in the little M15x

 

Hey M15X 7970m owners. Would one of you mind doing me a favor? I am curious about how much CPU power you need to not bottleneck a 7970m.

MSI is coming out with a GX60 which is a Trinity A10-4600m + 7970m for pretty cheap (hopefully around $1200 or less). The CPU performance of the A10 is very weak.. around the same as an i3-2310m.

For example Meaker ran metro 2033 benchmark tests with 7970m + i3-2310m vs 7970m + 2820qm

Metro 2033 @ 1080p, very high, 4xaa, 4xaf DX11 (no adv physx)
i3-2310 = 33fps
i7-2820 = 43fps

It is pretty hard to tell at which point between here the CPU stops being the bottleneck.. and well because you original i7 guys can OC and UC... I was hoping someone could play a little detective.

If any of you do happen to find the general area where performance shifts to the 7970m, would you mind doing a few benchmarks at that speed to give an idea what kind of performance is needed? (Cinebench 11.5)

IF TL;DR What is the lowest end CPU that would not bottleneck the 7970m a lot.

Thanks and many +reps.

 

It depends on the game and such. However the 920/40xm will never bottleneck this card. Otherwise I wouldn't go below a 840qm.

Considering the extreme chips capabilities with an aggressive OC it is possible to get performance at around 2820 -2860qm performance. At max OC somewhere between those two chips.

Basically speaking it would take a 2920xm OCed or 2960xm stock to BLOW away the old 920 and 940xm OCed to the max this is how good they are. Sure at such an OC these chips run hot but the raw performance is still there.

 

Any chance of someone testing draw at the wall with a Killawatt?

 

I have a 7970M in the post and a killawatt to hand. I shall try to do some tests on it. Although it seems to have problems working on Japanese mains voltage as I bought the killawatt in the UK.

 

Hopefully I will have a 7970m arriving next friday and a 920XM, I have also ordered the 240w power supply and an plug in watt meter, this will be my first major upgrade. Really looking forward to it, all going well i will put some pictures up. More than likely though I will be trawling through the threads for help.

 

I have the 7970M now but with major problems. Hope to get it fixed soon and start being able to play games again!

Edit: It is now fixed

Nice one. Now with a 920xm you might be able to break 7k

This card is great. With same settings red alert 3 uprising runs 20-25C cooler on the 7970M than on the 6990M !!!!!

I cannot run 3dmark11. Says that it can't have exclusive access to screen and or keyboard so aborts test...Even after I close all programs no go!

Also HWinfo causes instant black screen! Seems programs to avoid with this card are HWinfo, Furmark and GPUz for now.

 

Interesting, but as long as them games are running fine, nothing to worry about huh?

 

I am about to try 3dmark11 again. If I remember there was some update available which I ignored. I shall install it this time.

As for Hwinfo and gpuz I hope an official driver release from AMD will fix that.

Furmark runs fine but it seems pointless as all it does is heat the card up to point of shortening its life. I have got rid of it and many here agree with this viewpoint.

On the other hand WEI has dropped from 7.7 to 7.1 a score that I hope can be disregarded considering the non absence of Whqrl drivers from AMD.

Red Alert Uprising set to max settings at 1080p gets to max temp of 65C. The 6990M undevolted to 1V and stock clocks ran into the mid to late 80s C at the same ambient temp of about 27C! This card is really efficient.

Ok I have messed big time lol. Tried to reinstall 3dmark11 and it wouldn' run. Tried to fix net framework 4 and do a system restore and now everything is a mess.

Time to do a fresh win install. What a pain!

I really wanna get the 7970m but I was just wondering if anybody has had any problems from getting theirs at upgradeyourlaptop on eBay such as fan control or audio through displayport

 

The question you need to ask is. Is it a Dell card. Whether it is ES, QS or OEM Dell the fans will work. No idea about displayport though. Probably will work fine though. At least when decent drivers are out.
