M17 OC Benchmarking - The Next Generation!

I recon so, how will you be overclocking the 4850s?

 

I'm flashing them. gputool has been unstable for me.

 

Mission accomplished. Merry X-mas all!

 

Nice scores mandrake!

Pretty sure I am going to just stick to my M17x for now though, just throw some 4870s in it (done fussing with nvidia drivers!)

Of course, at the moment my SSD is dead

 

Ahh nicely done mandrake, what clocks were you running the cards at as the screenie for some reason is showing 500/800.

 

510|1050. Didn't notice the app was updating the clocks.

 

Dam, just goes to show the clocks can be pushed fairly hard, from what i can tell core clock effects the first graphics test more, and memory seems to effect the second one.

And you can get some extra marks from an optimised CCC setup .

 

Yes the 2nd test is memory dependent while the first is core. Same with nvidia cards there

510 core?! That seems VERY low for those cards.....I was running my 3870s in my whitebook at 745/1055 lol

 

3 series is revamped arch if i recall, they can stand the core being pushed, but the 4850s are dreadful when it comes to core pushing, mine decided to bug out at 560/950 (and that isn't even that much!) can run overdrive max 550 stable though.

 

interesting about the clock differences. But arent the 4870s in the M17x (Exact same GPU - M98 XT) able to run at 650 just fine? Guess it is that power deficit kicking in again

 

Well if they are m98 xts then they are built to handle the higher clocks anyway, i think there was once someone that had achived a 580/1125 clock before with his 4850 but ill need to check up on that.

 

I am pretty sure that the M17 4850s and M17x 4870s are both ATI M98 XT chips on the boards, can you verify this Mandrake?

 

Hmm interesting, well according to GPU-z (if thats accurate enough,) it seems fairly certain that the MSI 4850 is plain old m98.

 

Don't think that will show it, on the actual die it is laser etched with the model. In GPU-Z it wont show whether it is XT or not, the 3870s just show as M88 when they are in fact M88 XT cores

 

Interesting, then we indeed need a peek at the core!

 

That is why Mandrake is our man....probably one of a handful of people on this planet that have both a 4850 CF M17 and a 4870 CF M17x haha

 

great job!

did you try booting it in another computer?? or better yet...try it in your desktop. if you haven't this stuff already.

yes, but they would need more voltage...(speculation of course)

 

Tried the drive via enclosure on couple other machines, they see it as an unkown device but not a storage volume. Still working on it, but for now loading Win 7 onto a loaner 120gb 5400rpm drive we had lying around, cant sit here just doing nothing after all!

 

no the 4850s of m17 are m98
the 4870s are m98xt

ive had 4 now and all of them have been m98 they have all been lazerd onto the core chip

 

I see, thanks for the response!

That would explain the significantly lower clocks

 

man that stinks!..i have been freezing my drive while benching and it's been holding steady...so much so that i never even thought about the temps being to low for it..since the chips on your cards are pretty much the same chips...

the only thing i can think of why it doesn't work...is a drop of condensation landed on one of the chips inside..(speculation of course) you would have to open it up to verify.

 

condensation is all i can think of as well

currently have it on top of an AC vent to dry it out if there is anything in there, but not hopeful, it already had all night to dry out and it is not exactly overly humid in wyoming....

 

if it's not a chip, it's the controller board....which...i guess is the samething...just looked at the cover of mine and it has the sticker right there..else i would break it apart and look.

 

Same, if the warranty stickers were not there it would be apart and inspected

 

Awesome, kcuk, are both cards also using the same memory? Just curious, you dont have to know/check either hehe.

 

its the same chip but the MXM 3.o provides more juice and increased stability


that would be why

 

soz cat i cannot vouch for the memory for sure i did look and i (think) the memory is the same but i know deffo that the prozzi is different.

90% sure the memory is the same just clocked different

 

my 4850 can go to 610 and above just need to increase the voltage.

 

what voltage do you have yours at?

 

do you have separate voltage as well?..core and memory?

dt cards have this...was wondering if you guys have seen this with any of the ati cards.

 

i know for nvidia. you can't control the memory voltages just the cores. but i know in desktops you can control both and becuase you have a much better cooling for the desktop you can reach much higher numbers in those.

 

I use the flash method from Mandrake and it can go above 600 core when you crank the voltage up till 1.7v. The temperature doesn't change for me, it still idles at 47c and load at 70c+.

 

holy cow, 1.7? Ati cards sure go high.

 

yeah. ati uses more power then nvidia's. my belief is because of the old g92 core they keep on reusing.

 

True, the G92 has been heavily optimized voltage-wise at this point

I know my desktop GTX 275 cards use 1.18 volts stock on the core

 

The 4850 stock voltage is already on 1.5v. And I could only go up to 550 core any higher will cause crash in 3dmark and games.

 

if only the system could supply that kind of voltage and the voltage to the quad cpu's without the stuttering...

 

What's the easiest way to flash ati cards voltage? (im only experienced with flashing nivida cards)

 

Follow Mandrake's thread. It's has all you need to overclock and flash the card. http://www.notebookforums.com/thread230061.html

 

It's 1.05, big difference.

 

So he went from 1.05 to 1.7? wow....

 

I think its 1.07 sorry for the wrong information. I could not remember the exact voltage sorry guys

 

that sounds a lot better. 1.7 sounded insane for a notebook card. 1.07 sounds great and easily doable.

 

Regarding the clocks and voltage, I've learn from the 4870s that the memory clock can be OC'ed without affecting stability much. The core on the other hand is much more finicky.

 

It's the chase to 12K all over again.

 

with that dual getting p10k is very hard.

 

which nividia card has dual voltages. 1 for core and one for memory??? i had dual gtx295's and i used the evga voltage tuner for that. it can go as high as 2mv, but the average user is around 1.25mv


was looking at 1.7 about to say...yeah right...lmao!! you mean 1.07, but the ati cards can be up to something like 1.1 and run...ichime seems to be the king of volting in this respect.

 

I can't overclock my GPU at all. Once I overclock it, the screen goes blank. I even tried disabled the Crossfire first but doesn't helps at all. I'm using 4850. Anyone has that problem?

 

How are you overclocking?

BTW, Alienware has put some M17s back up on eBay. None look like a good deal at the moment.

 

I use GPUTool CTP1
