X7200 with SLI GTX 680m - how it works, Impressions, Benches

Because my buddy thought the 675m was a better choice than the the 680m

 

Hm, if we are talking about 1:1 yes, absolutely! But as I field both variants and tested them on stock settings I realized that the 675m SLI runs smoother in Games and is slightly above the 680m in Benchmarks. I already posted the results earlier in this thread.

Maybe a single 680m is more overclockable than the 675m's, that I cannot say. Eventually I will try out some Overclocking, let's see....

 

1: A single 680M is way more over clockable.
2: It's one card, leaving him plenty of upgrade space. Which you lack when running 2 675M's
3: And single card setups always run better than dual/tri and quad card setups from my personal experience. More fps? Sure. More efficient? Not even close. Example: Meaning adding a second card directly doubles performance. Which is not true. (Yet. But getting closer as the years pass buy)

And we checked on 3dmark and hwbot.
And when you go up in resolutions it gets even worse.

That's why I ask in the over clocking community, because these are the people who find out what products are really made of. Example. When Meaker posted his world record thread. And right after that, everyone said dell cards were no good and that clevo was king. And that a single card kicked the 580M in the behind. Had he not went out and found out what his card could do, then we would all asume they all were junk. Although that has since changed and dell cards seem to be far better in sli now. Still working on clevo in sli. It's coming along though.

But if you can point me to someone that has "over clocked" results for the 675M. That would be great! Since he has no plans on running stock.

 

The 675M/580M reaches around the same core clocks as the 570M when pushed, about 800-825mhz, but it has a tendency to die at the higher voltage IIRC.

An overlocked 680M can maintain a 40-45% overclock if taken care of it and at that point it still keeps ahead.

 

Hi @ all,

back again! But unfortunately with bad news....

I've tested my GTX 675M SLI in oc mode via EVGA Precision 3.0.4 (I was afraid that oc via flashing the vbios would be too risky as a newbie), when my X7200 was immediately shutting down while running 3DMark 11.
My actual overclocking rate was 750 Mhz Core clock and 1725 Mhz Mem Clock, which I thought that would be absolutely safe!
I experienced no artefacts or other bad reactions, temperature was about 77° while showing the demo movies. As it came to load up the first testing mode it suddenly "crashed" down. All went down and my power brick wasn't showing the green light. So I waited for several minutes and try to restart my X7200 again. But the only result I got was that the notebook went on but the screen remained black. I am also pretty sure that Windows didn't load up because the volume lights as well as WiFi lights didn't show up/turn on. Fan's are kicking up to 100% at the beginning and then they slow down after a while.
What also seems strange to me, if I turn my NB on the power light is blinking a few times and then switching from orange to green. What could that mean?

So my question is: What have I done???
I really hope that I didn't toasted my cards or something else. Did you experience similar effects while overclocking? What can I do to restore default settings and get my X7200 working again?

Thank you for assisting me in that. I really hope that I haven't to face the worst case....

 

P.S.: I overclocked my GTX 680M with no problems at +135/+600Mhz with the same tool which was the reason I thought, I could do the same with my 675 cards. Safe mode/reference data's for the 675m were 800/1800Mhz from what I was reading in other threads.
So I have absolutely no idea why my cards crashed down at 750/1725Mhz? Aren't software tools like EVGA Precision not able to maintain such "high" overclocking rates? Could it have been a voltage problem?

 

What powerbrick are you using? IIRC clocking should only be done with the dual 300w setup.

 

Maybe it´s the power brick as meaker said, look at what Myrsprett wrote some time ago:

 

Hm, stange! I think it's the standard brick with 330W. I've never heard of a 300W dual brick. Where can I get that?
Do you think I "grilled" my power brick? That would make sense as I only get a black screen after switching my Notebook on. No Windows, nor Bios screen at all....

 

I don't mean to sound alarmist but a brick going pop is perfectly capable of taking everything else connected to it with it.

 

Hm, I think 300W is the standard.
This is the box you need (plus another adaptor):
CLEVO Power Converter Box for Clevo X7200 Notebook : AVADirect Custom Computer Component

Just ask your reseller if he can sell you one. Everyone who sold X7200 should have it... In Germany you could contact Clevo at Goldenstar Computers.

 

Ähm, you're just about to scare me to the bones! Okay, let's play this worst case szenario: how can I check which components were grilled too, if it is the case? Or is the only thing I can do throwing the whole notebook away???

 

Do you all field 300W dual bricks? Is this standard for overclocking components for X7200's?

 

I just had a look at

Clevo Germany

but they only sell power bricks up to 150W, and it comes with 75 €. Oh dear, what a mess!

 

No, they sell almost everything - they have almost everything. They do the RMA in Germany for many resellers...
I bought from them graphic cards, heatsinks, screw sets and many other things. You just have to write them. Sometimes you have to remind them, often they reply only after the second "reminder" mail, but the deals are perfect and they ship fast.
Motherboard for X7200 is 200 Euros if you buy from them (netto).

 

BTW, did you try remove the battery?
Or start on Battery only? Or on AC only?
And try remove the battery and RAM and plug off AC, then press the power button for about 30 seconds... might help, too.

 

After the third try I noticed that after switching on the NB not even the SSD was responding/working. So I presume that at least the mainboard could be defective.
Is there a possibility how to check which components could be defective? Without knowing ordering spare parts won't make sense.

Puh..., to be honest: At the moment I do not really know what to do. Any ideas are most welcome.

 

I tried only with battery, with the same result. But I will try the remaining alternatives too.

 

Didn´t see that before...
I personally have only one adaptor... never had problems before.

 

You only can check each component after each component. Take out 1 RAM, then the other and so on.
It could be the CPU, too. I couldn´t start my X7200 two months ago - screen stood black. It turned out that my CPU was defective and 1 RAM slot, too.

 

Would anyone have videos with BF3?

Hello all, I've been lurking on this thread for a long time now. If I'm to understand correctly, 680m's in sli on Windows works fantastically well with some excellent overclocking. Now, I have mainly switched to Linux and am wondering if sli works in an ubuntu system. I use it for gpgpu processing and stuff. Also new Steam beta on Linux.

It can easily work if you incorporate it within the vBIOS. Linux gives you loads of other options for OC too

 

Yes! That's what I thought and was hoping for. Perfect. I just wanted to double check and make sure before I drop $1000-$1500 for some 680m's.

Edit: I'm also jealous of your speeds jaug1337. Very jealous.

 

You are most welcome

Oh you will be fine, it's my school network at it's peak, hehe.

Do you have a Windows OS right now? I would rather do a dual boot to be safe.

 

So I had the time now to go after the defective component. I checked the RAM's and the graphic cards. They are okay. As I don't have another CPU to check I don't know, if it could be the defective part, nor do I know, if it could be the mobo too?
What I was also trying was to remove the CMOS battery but I didn't manage removing it. How do I do that? Do I have to remove the plastic frame first? There is nothing mentioned in the manual or somewhere else how to remove the battery safely without damaging something? For I am afraid that I bend the bracket too much and it seems that it doesn't touch the battery anymore.

 

Okay, problem quasi solved! The notebook is running again.
It seemed that it was in some sort of "sleep-mode" and it turned out that by accidentally disconnecting the cmos battery from the mobo the correct settings were restored, et voilá!

If someone can tell me now how to remove the cmos battery safely, I would be able to bend the bracket back into the right position and all is fine again!

I will order then a second psu and see, if oc will be safer then.

 

Glad to hear your X7200 is living again !
Let us know some new oc´s when you´re ready!

 

Hi Tirenz,

yeah I'm happy too! :thumbsup:

Do you eventually know how to dislodge the cmos battery? May be you can have a look on my post on this thread:

http://forum.notebookreview.com/sager-clevo-reviews-owners-lounges/486713-clevo-x7200-sager-np7280-owners-lounge-635.html

 

All is fine now! I finally was able to dislodge the battery!

Thanks to Meaker again!!!

 

Always happy to help Glad you have it sorted.

 

Anyoen tried the new 1.05v vbios from slv7 and can link 3dmark score?
what OC are you guys using as stable gaming clocks? been away for a while and need updates

 

I tried it, it was performing nice, but didn't add much to the stability, couldn't go higher than 1040/2400 and even that crashed at the last 3dmark11 test. I noticed I could game @980/2400 stable with the 1,05V vbios, but the few fps more are not worth the extra heat (+5°C) in my case.

But I'm happy with the performance at 915/2200 which I apply for almost every game 24/7 (and I'm using the "old" .33 revised 01 vbios that has no voltage tweak.

 

Interesting that the voltage did not help as most 7970M cards seem to scale pretty well with it, I guess all cores are different. The card can be pretty picky about power delivery though.

 

Ive been trying the 1.05 vbios for some days now and I must say im pretty happy with my results.
I can game stable at 1006/2500, I tried to put it higher but resulted in artifacts. In 3dmark 11 I score 8k singel and 15,5k with sli. I may be able to score higher by oc more but it will not be stable in games.
My gpu reatch 82c at max with no fn1 when gaming crysis 3 for 2 hours. Some people claims to reatch 1100/2500 with the 1.05vbios whitch is insane overclock and hit 8,7k in 3dmark 11.
But to reatch that kind of score you need to win the gpu lottery, whitch is extremely difficult when you go for a sli system.

 

Very interesting results!
In a few days I will have some time to try the 1.05 volt vBios and put some Benches online .

 

1.05V is only giving you 1006mhz? Did you check your load voltage when in a game?

 

Newest Beta driver, SLI

What I did? I just installed the new driver with modded inf, and did the SLI Hack for 310.70 again. Worked for that driver, too .
(I tried that with the old hack before, that didn´t work)

 

Hello, dear Sirana!

Can you ask guy from one.de - can he adapted bios from w870cu for GTX670M?

(my email [email protected])

 

Is that the song in the 5th element ?

Hello!

We I are can download bios x7200 which support GTX680M?

 

Just use the latest one of this website: Clevo x7200 / Sager NP7280 BIOS MODS With Unlocked Overclocking Options

Direct Link of 728BV13S.ISO: 728BV13S.ISO

 

Yes, use the one sirana showed you, but remember the GTX 680m is NOT officially supported. Using one GTX 680m, you have to use modded infs (there is a very good guide from sirana in the first post of this thread) and if you want to use SLI you have to use the "different SLI hack", as described in the first post, too.

 

Yes I did check my voltage in game. But with stock voltage I was not able to put it higher than 900 mhz.
I may be able to put it higher if I lower the memory clock. I know my gpu`s are not the best compare to others,
but 1006/2500 is still a pretty decent overclock if you ask me.

 

One of my GTX 680m just died .

First at a Benchmark, there was an error, followed by the slave GPU showing an error code at the device manager.
When I reinstalled the driver, there was a bluescreen about some clock interrupt and then black screen.
Turned off the X7200, and on again; black screen, no bootscreen, nothing.
Took off the cmos battery and started again; same black screen.
Tried the RAM, nothing changed.
Now I took off the slave GPU, and it starts again without problems. When I put it back in, black screen from the beginning...
So I think it´s pretty obvious that my slave GPU just died... will contact one.de...

 

What really?? So soon? That's a ton of bad luck
Was that with the 1,05V Vbios? Did you watch the temps while benching?

 

No, it was the .33 1V vBios.
Was just benching the new 3DMark...
Temps were all right. They never ever got over 82°, no matter what game/ bench was running.

 

That sucks man.. Did you try flash slave card back to stock?

 

I can´t. When I put the slave in the screen stays black... and think there is no boot or anything in the "background" to blindflash...
