Undervolting also doesn't allow me to OC as high as I want.
It's more like a CPU downclock versus a GPU stutter. Very apparent when doing the CPU test in 3DMark06. If the GPU stutters I can usually tweak settings to fix it.
-
-
The cpu will underclock and undervolt by itself after heavy load and when the cpu does so then the stutter will kick in. After awhile the fan will goes off and the stutter is gone. That is what I'm experiencing with quad core.
-
I have my 3870s back in and I'm going to do a stock run and OC'ed run to see if I see the same issues.
-
so the processor has enough power but stutters when it ramping up and down.
,,,, so its like manual car going from 1st-3rd and missing 2 -
Ya for me there's no stutter when either it is underclocked or overclocked. The stutter only comes in to play when the processor switch state. I have my p8600 in the machine now because the stutter is really annoying
-
The issue is still there just not as apparent. When I run the CPU test by itself there is no issue.
-
Mandrake, i've noticed the 4850 in my machine stays at full clock if its on dual screen so maybe occupy your machine with an external display? (unless since its two cards they operate in low state.)
-
I'm trying to prove first that it's actually happening.
-
Yeah its a fairly strange issue, if you are having a small time case of stuttering though, check the 4850 temps of the memory diode (everest might show, did for me) but when i was hitting like the 88C margine i believe i experienced slight stutter, although if its happening while your setup outside, that would be quite strange indeed.

It's the quads that seem to get it, not the duallies! -

Wasn't Mandrake also testing with a T9900 though?
-
-
I don't know but I need a break from this before I go insane. This makes me really appreciate the M17x.

I'm out of thermal paste anyway. I have more coming Wednesday. Sounds like a good day to try again.
-
im still benching...lol
damn, benching all my old stuff i had laying around
sounds like your right...might need to relax a bit before getting back to it. -

I am ready to go full blast if this stutter stuff ever gets fixed......hard to get excited for it though when stutter keeps ruining my efforts
-
all the stuff seem to be fixed for now i played all day no lagg stutter or slowdown hapened i only needed the right voltage for my cpu
-
everything seems to be at a stand still...do you get stutter at 1280x1024?
-
cookinwitdiesel Retired Bencher
I still stutter yes
And I am referring to my M17x of course (all I got at the moment) -
even with c1e, speedstep and thermal throtling turned off with the 4850's my freinds is still stuttering with both b14 and .29 has to be something with the 4850's
-
well this is a bad....turn of events.
-
i had a system in hand last night with the 4850's... from a local friend i have let me play with his system last night i had the SAME issues you are mandrake with the 4850's i opened his up and put his old 3870's back in and none of this garbage with them... this sucks. i am totally unsure what at this moment is causing this from the 4850's they really should not be acting like this.. he has crazy stuttering with them. NONE at all with the 3870's and he has the copper shim as well. his system is smooth as can be with the 3870's but even WITH THE COPPER MOD stutters with the 4850's... what the heck is going on here im not sure yet
-
voltage...would be my guess...as usual...
-
yeah as i have said many times. the 4850's are not that much more hungry then the 3870's were though. i would have taken my best guess to say they should have been okay but are not. thats why when slightly undervolted there are no issues at all as i found myself. even WITH .29 installed with just a small notch down on the gpu's we had basically no stutter especially compared to what we saw when we first had the issue. with dual 3870 and the .29 with the qx9300 overclocked to 3.06 and the copper mod his system was totally stutter free without issue. i could not even get the 4850's to run stutter free at STOCK speeds without lowering the voltage
-
Just found my benchmark screenie
-
TURN THE DISPLAY BRIGHTNESS DOWN! lolol
Its really strange why its being quite inconsistant,
good run there adam, have you done any vantage? -
-
What kind of temperatures were you getting on the 4850s z?
-
dondadah88 Notebook Nobel Laureate
adam
what is your cpu at?
z
have you tried to undervolt the cards?
or try another cpu in it??? -
only a few degress higher than the 3870's nothing to worry about.. i dont remember exact numbers but when we were watching temps last night we were suprised actually that they were not higher
-
Thats good, i wonder if its something were completely leaving out the picture then,
-
dondadah88 Notebook Nobel Laureate
not really when you think about all the other things we have tried.
the only thing that is different now is the cards being swapped...
which can say two things
bad cards
to much voltage
try it with one card and see what happens... -
So my issue isn't common. Do you still have the system z?
Temps can't be an issue here because I was doing a lot of the testing in the cold, bottom off the computer and on top of a cooler. -
one card still stutters!!!! we tested that also
ill have it again tonight. but no shinj has stuttering he has 4850 at stock speeds even it stutters, this system did, yours and someone else here also i dont remember who it was had 4850's also with stuttering. seems this one difference is the cards. and i worked the .29 bios with the 3870 cards so i didnt see any thing from the 4850's so i could of course not have known -
-
-
we tried b14, .28 .29 and even a couple older aw bios' with the 3870 .29 was perfect. with 4850 sadly was not. his system stuttered even with b14 though at stock speeds with BOTH 3870 and 4850, so far one person has undervolted the card and said his issues went away but the cpu was stock speeds...
and yeah this all sucks -
dondadah88 Notebook Nobel Laureate
swap cards then????
i don't believe one card would draw so much power unless it is the socket it self not giving the power out.
downclock the cards
put the cpu to 6x which is 1.6ghz and undervolt the hell out of it.
if you use rmclock and can't go any lower but don't bluescreen, use cpugenie and uncheck the vid settings and you can go lower with undervolting.....
running what ever you was testing with 2 cores or posible one core and see what happens
maybe a bad bios on the cards....
someone without stuttering regardless of what cpu you have with the 4850 link there bios on there and they can see if it is different... -
dondadah88 Notebook Nobel Laureate
z do you have any ideas other then the motherboard is better on the np9262???? -
-
-
cookinwitdiesel Retired Bencher
those voltages have to do with the power circuitry on the MXM card itself Don, not the motherboard. Just like Intel and AMD CPUs will take different voltages.
And yes, the motherboard was undeniably better on the np9262 -
dondadah88 Notebook Nobel Laureate
yeah mines to but i had a dual and one card so it didn't have any problems compared to the w840 and the w850
-
TurbodTalon Notebook Virtuoso
So these 4850s are a bust, no matter what CPU/Voltage?
-
cookinwitdiesel Retired Bencher
starting to look like it
-
TurbodTalon Notebook Virtuoso
DHC bought those 4850s from Kcuk, and I haven't heard anything negative there yet.
-
I got no problems with my current M17 at all....from what i read most got problems in combination with a QUAD...yet Maximus has no problems with his Quad M17 & 4850's...hmmm strange
.
-
TurbodTalon Notebook Virtuoso
Right. It's impossible to track down a problem that is inconsistent. I got rid of my Quad for an X9100 two weeks ago, and the stuttering is GONE. I would have to put a vote in for the quad cores being an issue as well. Not that this is the first time that has been mentioned.
-
yep ill second that no issues what so ever ( except ive forgotten how to mobility mod it seems)
ive had no issues with bf2 codmw2 pro evo grid dirt 2 nothing and ive only got p8400 in my laptop at the moment.
witing for the sales next year and to see if youlot can fig out whats up with qx9300
as it is having problems with other laptops i cannot belive its bios motherboard related as theirs a few with the qx9300 stuttering problem
my 2 cents is that its the processor driver thats comes with windows. its dated 21/6/2006
