7970M Problems

Note, that even at stock voltage, when you raise the clock frequency you are putting more load on the voltage regulators, and that may or may not cause issues. I highly doubt it would and when I get my 7970m I WILL be overclocking it I believe these things will be able to overclock a lot, stock I believe is 850Mhz, and I have little doubt you can see 1Ghz on a good overclock.

 

yup, 1Ghz is no problem whatsoever. highest stable clocks ive see so far were by halogod2012 with core 1020 and mem 1660

in numbers: thats a whopping 6.84k in 3dmark11 and 24.05k in vantage!

cheers

 

are you using the free version of 3dmark11?

 

yup. either way, it has what i need.

 

Is there any fan issue with the 7970m on the Clevo P170EM?

On my P170EM/7970M the fan doesn't reduce the speed after ending a game.

 

I would just give it a small OC like 10% and get to 920mhz or so; beause honestly why not haha. Your temps will still be below 75C even. A GTX 675m or 580m STOCK will hit 80C if you live in an area where ambient temp is 75-80F. So if this stays in that same heat range whiel OC'd you are perfectly fine, a 10-15% OC is not going to do any damage at all. Then again; you can probably max everything out without the OC. haha.

 

There are no known issues with the fan controller or speeds on the 7970M equipped Sager laptops to our knowledge.

Does the fan just not reduce speed at all or do you think it is taking longer than usual? If it does eventually reduce speed, how much time does it take?

It really depends on where you live, the fans are set at a certain RPM for a given temperature and won't wind down until they hit the target temps to trigger that. Considering that summer is here and it is warming up, your ambient room temps will play a role in how long the fans stay running.

 

The fan doesn't reduce its speed at all. Only a reboot can solve this problem.

Also by installing the actual AMD driver from the DVD again or by trying out all BIOS versions (1.00.03, 1.00.03b, 1.00.04) there is no speed reducing.

I tried to install MSI Afterburner (also with unlock), but this program constantly shows the fan speed with 0 rpm, the GPU temp is not shown at all.

I am rather confused by this issue.

 

hm wasnt there a thread about this exact problem just weeks ago,only with one of the 81x0 sager models? pretty sure i saw this exact same fan issue. u should go check the older threads or google is (search function here s u c k s ) maybe theyve solved it by now

Thanks for this tip.

But I am not able to find a matching thread.

 

For some reason MSI Afterburner is saying my max clock speed is 850 MHz and I can't set it to anything higher

so much for that....

 

My experience with overclocking video cards is the first 50% of the stable overclock results in a noticeable boost in frame rates. The last 50% is mostly diminishing returns.

 

did u follow slicks OC guide to the latter? and did u check ur clocks under load? it usually just shows u stock clocks until u put some load onto the gpu.

cant generalize it like that, depends on if a specific application is bottlenecked by either gpu core or mem throughput and that only if ur gpu is the actual systemwide bottleneck.

That's just my personal experience but I've been overclocking since Voodoo 3, GeForce 2 days. I do recommend verifying what your actual frame rates are in game to see how much overclock is worthwhile.

 

been OCing since voodoo 1 days, still holds true

Seriously this Enduro is crap, can't wait for AMD to fix this.

 

It's certainly true overclocking won't yield any benefit if your GPU isn't the bottleneck. The point I was making is that increased benchmarks have not correlated well with increased frame rates in games for me personally when you get to the upper ranges of the max overclock. I haven't done much overclocking of late but that still appears to be the case based on overclocking reviews I have read. However the 7970m seems to have truly exceptional overclocking headroom so it will be interesting to see how it pans out. I will probably even overclock it some myself although I won't overvolt it.

 

yep same here i only go as far as the stock voltage would let me, had some bad exp with a fried gpu ^^ and tru that, its funny how well the 7970m responds to mem oc altho that normally doesnt really do much in terms of benches! if the initial 680m benches hold true ill go amd all the way this year

I read today that 7970m is soldered to the motherboard of Clevo P170EM. Meaning I can't change or upgrade the GPU in the future.
Is this true? I thought P170EM was an upgradable laptop.

 

huh? where did u hear that? source?

definitely not true btw, aside from minor changes the EM and HM series are all the same,thus support mxm gpus.

What? No it isn't. It's definitely possible to remove it

 

Dude we already replied to this in the other thread, please refrain from spreading false informtions.
As long as u do keep asking the same question, ure helping that ignorant troll.
No offence, just sayin'

 

Hi there.
I thought that those stock temps of 72°c were the max. You said this is well below the max temps the cards are capable of handling. I don't think that's true. The core may register a temp of 72° but other areas of the GPU would be at 100°. So 72° is the max for the core itself. If it exceeded that, then other areas of the card would exceed 100°. Not a good scenario.

 

No the core is the hottest part and it is rated to at least 105c. 80-90c is hot but NOT A PROBLEM. READ THE SPECS!

 

I was reading somewhere, either in this forum or on a review of the HD 7970M that people were confusing the core temp of 72° with the max temp. It was said that when the core reaches 72°, other parts of the card are at 100° and if it went higher, those other parts would also go higher above 100°.
If my reading is wrong, I apologise.
