7970m...how high can it overclock?

Title says it all how high can you OC it without voltage changes.
Then how high can you overclock with voltage changes...anyone got an idea?



BTW I thought i had more than 3 line sin this post....weird maybe another thread....ah it was the 680vs 7970 i had updated.

 

@ stock voltage on a dell card, for me, its 1ghz core 1.5ghz vram

Geo was able to take his 1020mhz core, 1.55 ghz vram

For everyday, i game at 950/1375. however, even the stock 850/1200 will produce very playable fps in every game out there

The clevo cards typically come with slower vram, so those cards may not be able to pump up the ram as high...and although pumping up the ram past 1100mhz in the 6990m didn't make much of a difference in benches, i'm seeing huge differences going from 1200 to 1450mhz. The 7970m can make use of the additional bandwidth

 

Got benchmarks in my sig, don't think this card can be overvolted..

EDIT - It can be!

 

That's just SICK Geo....SICK!

oh i asked somewhere else and no one answered the dell m17x r4 has the 7970 and what not but what mxm board does it use? Will i be able to upgrade to the next card or two? I would plan on upgrading my graphics card 2 models down the road if i can

also why can't you up the voltage?

 

it uses mxm 3, dunno about the variation though.

regarding upgrading in 2 years its up to nvidia, since they are the ones that make the mxm standard.

 

i personally thought the 7970m used the mxm 3.0C standard

however, according to this source:

2GB GDDR5; AMD Radeon Mobility HD7970M (Wimbledon); 1280 Stream Processors; 256-bit; GPU 850MHz; VRAM 1200MHz; MXM 3.0b; 100W

Currently, the bios on the 7970m is locked...so you won't be able to up the voltage on it. Its also protected by the drivers which prevent it...so says the author of RBE

now we were able to extract the 7970m vbios using a bootable USb and ATIFlash, some values were editted but at the time we were too chicken to flash it back.

Maybe geo has more insight...did you try something recently Geo?

 

Benchmark tessellation load modified by AMD Catalyst driver, result invalid. Check your video driver settings. (What is this?)

 

^^^ that just means its with tess off

 

I know but it's still invalid .

 

well...perhaps, but its still nice to see that ridiculous number lol.

Geo scored 6800+ with tess on in 3dmark11. So this is valid:

I'm pretty sure anything can be overvolted. Have you seen this?
[Mod] AMD 6970m voltage mod (*working*)

 

svl7 is a tech wizard. ya, i've seen that before, but i'm not doing that on my 7970m lol

 

I didn't know this is the case, hope it isn't true when Clevo gets 7970m

ya, the dell cards come with hynix ram that clock really high.

The clevos generally come with lower spec Samsung ram

 

We'll see.. after all it hasn't been tested yet, as you said...

Well, I don't blame you, hahaha, wouldn't have done it either if I were you

Hope I can find some time during the weekend.

 

If anyone on this forum can update and flash a new vbios on the 7970m, you can. I have my utmost faith in your svl7

 

yea i am going to take you can over volt it by flashing so thats good news for me 1-2 years down the road when i want to explore that option. So any more info on the upgradeable? I would hate to buy another laptop like my g51j lol. I know people have replaced the dell m18x with 6990s with this card so what does that mean on mxm board? Is there any other way to find out about mxm board info and if its going to be replaced....i will be so pissed if i can't get a new card in 2-3 generation because that'll make a huge difference in this things life. I plan in 2-3 years to get the ivy bridge XM for super cheap and get a new gpu and it would be like a brand new laptop!

 

mxm is done by nvidia, there is only one way to know if its going to change or not, if you are working for them in the mobile area

 

is there a reason to change it? isn't it already PCI express 2.0? so its not like a bandwidth issue will arise

 

the pcie lane is about 8x in my laptop. So as the cards get more powerful, we'll need to increase that.

 

8x? are you sure its not 16?

 

Did you know that those drivers that you are running on has PCIe 3.0 enabled as default specifically for 7970m. As I remember the new Panther Point boards support native PCIe 3.0. I will try test turning that on and off when I receive a Clevo (I believe it has native PCIe 3.0 support as well as the rest of this year models)

Often, the board shares with other stuff, 2x for this, 4x for that and what you have left is one for GPU

1?....1x??? Seriously? I thought there was a 16x pci for gpu 1x/2x for wifi and so on. Not 16x total and thrown around for everything. How can it be shared? They are all on different slots. You got 3 pieces of hardware daisy chained to the gpu port?

 

Would the PCI-E lanes on the pm45 chipset bottleneck a 7970m?

 

from AnandTech - Intel's Sandy Bridge Architecture Exposed

 

I meant the lane not the speed..

 

yea 16x 16 lanes is there a difference wildkid? So a laptop only has 16 lanes total for a combined 16x speed? why would they do that?

 

Interesting! when are you getting your clevo? I'd love to see the results of your testing

 

PCI-E 3.0 helps several setups:

Optimus
8x/4x/4x on z77
8x/8x xfire/sli (a little bit)

 

2 months brooo lol...

Intel HM77 indeed supports PCI-e 3.0 1x16 or 2x8 with ivy bridge equipped.

If you modded 7970M bios, what values did you replace and by how much? If its decent, then i wouldnt be afraid to flash it with atiflash. Even if it doesnt work, you can always flash back the original bios with intel IGP enabled.

 

HEre are a list of overclocked dell 7970m vbios'

So far, you can undervolt, and set the core and ram clocks, however, you can't overvolt. SVL7 sent me this:

AMD 7970m - modified VBIOS

 

pm45 chipset may be mxm II or mxm III standart not mxm b. I know two types of Ati 4650 mobility cards some are mxmb some are mxm II. First be sure it is atleast mxm-b. And some people say 7970m have mxm c type. If you can fit 7970m, yes possibly I think you will have some power and bottleneck issues.

 

lmao this is insane, but it doesnt look like we'll even need to OC the 7970M to play games at ultra setting below 30 fps.

 

Apparently, the voltage can now be tweaked for maximum overclocks.

Arrghhh, the wait for my new toy is unbearable!

 

i believe mxm3.0b is backwards compatible with mxm3.1.

 

There are quite a few Acers with MXM-A slots on a PM45 chipset that you can make room for MXM-B cards.

Also to answer niff's question, no, it's 16x Gen2 IIRC, at worst 8x Gen2 which is still plenty for a single card.

 

mxm a and b
is just if the connector are on the wide or short side
mxm 1.0 mxm 2.0 mxm 3.0 is dif connectors and they are not itershangeble
mxm 3.0 and mxm 3.1 if both are b you can use the same card in both
c conbined with 3.1 im not 100% about but i think it is the new pci 3.0 and it should be backvards conpatible

 

What is this 3.1 stuff?

Old mxm is : MXM 2.1 - I,II,III, IV and HE. All of these cards except the HE (which was practically the same as the rest just with an added power connector) used the same connector. Of course the different types were of increasing size but the connector was the same.

New MXM is called MXM 3.0 which comes in 2 sizes MXM type A (midrange and smaller) and B (bigger) both use same connector. I have never heard of MXM 3.0 C before reading this thread...

 

i was looking abit and it sems like its the new pci 3.0 but is bacward compatible with 3.0
i agree that 2.1 and up is the same connector on the 2 series but 3.0 is not same as 2... series
A and B is also one is placed on long side of the card and the other on the short side same connector but one will prob not fit in the other since cooling and the placement of the card would be totally difrent do you agree?

 

It depends if the laptop has space for a mxm B card. In this case both A and B would fit fine and be cooled adequately. For example I could whack a type A card into my m15x no problem.

MXM 2.1 and 3.0 as you say are not interchangeable.

 

if you have space and the cooling works then no prob
mxm 3.0c or/and 3.1 or if its 3.1c cant remmeber excact
i just read on one of the GPU thread that it was for the pci 3.0 but would be backward compatleble with 3.0
but in case of new card and old motherbord gpu would only run in pci 2.0
and same if other way around

 

There's no MXM 3.0 C.

Take a look at the post of the King of Interns, he got it right.

MXM 3.1 apparently adds PCI-E 3.0 to the specs, nothing more. Connector stays the same and there's still only module type A or type B.

 

thanks for clarifying that the name of the new mxm is 3.1 as i say i had forgoten
i didnt say he was wrong !

ps are you the same svl7 thats on MVK

 

The very same.

 

nice didnt you find the way to ov the 7970m

wish some one would find out a way to up the volt more in the 485m vbios over the max that nv have set

 

how?

Edit: Nevermind. I missed a few things over the weekend away

 

ok then what am i missing? What is he referring to? Also is the R4 mxm 3.1? Does it support pci 3.0? So lost. Someone needs to make a guide explaining all the types of mxm boards.

 

well what is the max overclock now that you can change the voltage ?
