M17 OC Benchmarking - The Next Generation!

in benchmarks or real world though....cant ignore the architecture advancements

 

ok then lets compare the 4850 vs the 3870 stock then. anyone has dmc4, fc2, or any games. prefer the 4850 since they are rare.

 

all i know is they said that is one reason for them dropping the system if you may know who i mean now said after testing them pre release wise they were very dissapointed i think if you remember me telling you that a long time ago also don

 

Only a few guys have the 4850s. Hopefully they'll post some benchmarks. Are DMC4, FC2, SF, etc. considered a real-world benchmark?

 

yeah but i was able to play with them pre release a long time back as well as the people i personally know at ocz were....i didnt get to see them to long since i had to send them back as they were for testing only. but the person at ocz said he was dissapointed with them

sucks they are basically gone from ebay now.. guess im out of luck since i passed on the ocz deal i had

 

what notebook are you going to go after now then?

 

That is interesting, given the performance they should be capable of

Is it just because they have to be so downclocked for the notebook cooling?

 

well 500/800 is very low for stock.

 

because the desktop 4850 is roughly the same performance as a desktop 3870x2

 

Mandrake is still having technical difficulties I think. When he's got things all sorted out, he'll no doubt post a bunch of benchmarks. That's when I'll make my decision.

 

yeah me as well i do hope they worked these more than the pre release ones were hence the reason i wanted them but unless they are better than this i dont think they did much

 

We have known for sometime they were not twice as fast as some people claimed they would be against the 3870s .. All my benches against Alexrose's machine showed about 15-20% if that... They should shine though in certain games like Crysis under DX10 where the 3870s just crumble, but for most games they were just marginally faster...

 

hmmm, all this talk is making me alot more ok with just 3870s....if any M17's ever come on the market again

 

If you can get the 4850s for the regular cost that Alienware charges then it would be worth it IMHO but not for $800-$1000 thats for sure ... For the regular price you can sell your 3870s and only pay a small amount to upgrade which was my intention before selling my M17 thinking i could never get the 4850s...

 

I may do that, but can the 4850s be OC'd at all? And you have to be the original owner to order the 4850s, or know one you trust.

 

i sold mines cause i couldnt wait any longer for the 48xx cards. so i didn't even know what performance the 4850(suppose to be 4870 with gddr5) had. but paper always seems nicer then real testing. 800sp vs 320sp. that alone made me sold. lol then double them for crossfire 1600sp vs 640sp... the 3870 in crossfire still doesnt have the same sp as one 48xx

 

Im sure they can but to what extent im not sure.. I know Alex did some OCing on his but i cant remember how far he got.. I imagine if you have some massive cooling or are standing out in the freezing cold you could make some nice headway ..

 

They OC similar to the 4870s. You cannot push the core much but the memory is a different story. My problem is the inconsistency and I cannot figure it out yet. One run I'll score 17.8K and the next with the same settings it will be 14.1K. Very frustrating.

 

How much stuttering are you seeing during those runs because that sounds familiar to what i saw when getting the copper set just right on the NB .. Could be a power issue as well as id imagine the 4850s require abit more juice...

 

Let me know when they go up for sale Mandrake.

 

that just sounds like the usual stuttering haha

are you seeing any?

 

The copper mod I did with the NB seem fine with the 3870s.

The the GPU stuttering I can control easier than the CPU slow downs.

 

you run and hit this

try again


then try again and hit this


so depressing sometimes.

 

It's the exact same thing. SM2 and CPU are affected much more than SM3. I did NOT see this with the 3870s.

 

Have you reseated the CPU and NB since you put the 4850s in ? Might be worth a shot just to redo everything and i only say this because i had many different results with my scores till i found the sweet spot getting that copper just right... Don can vouch for that ...

 

yeah i can.

it will make a big difference on how your system responds.

 

Yeah I did when I first installed it and again today. Still kind of hard to believe heat is an issue when I was doing a lot of the testing outside.

 

Have you tried it without a Quad cpu?

 

Yes, I tried with a T9900 earlier. Wasn't as obvious but still there.

 

undervolt the card then try to eliminate over draw on power

 

it will seriously suck if the limiting factor is indeed the power supply for the machine

 

M17x powersupply works great on the M17 FYI .. I used it all the time ..

 

sounds like you need a ups or kill-o-watt meter to gage your wattage.
run just one gpu and compare it to the msi thread gpu runs...and we can get a better perspective on it all....

edit:
no, that would be a good thing..because you can have one specially made for about 350 bucks. they have a place out here in irvine. that i know of...

a guy had one made for his d901c. original power supply was 220 watts...his new one was 350 watts...i think his name is gangsterone.. i think he is still around.

 

I've been thing along the same line you guys have. Except for john, I have a kill-o-watt meter at work but not home. I also tried the M17x adapter and it would shut off early on during 3DMark06.

 

Hmm that weird as it puts out more power and i did tons of runs without issue..

 

Sounds to me like your system is failing ...

 

I'll give it another go.

Yeah I can see that tech call right now, me complaining about stuttering every time I bring my CPU over 3.4Ghz. What do you think the outcome of that would be?

 

Just saying .....

The m17x psu does work perfectly I have both at my disposal as well

 

Not the same situation.

 

nope...it's not enough power for some reason...

does it shut off with the cpu at stock and the gpus running full on?

and the m17x was designed for this where as the m17 really wasn't...(now this can go either way, but wont know till you either waste or invest in a built power supply with more watts..... this is where things start to get interesting in the benching world...lol....the bencher will buy..the casual will say..to hell with it...hummmm...lol...)also...the adapter is power regulated and will rise and fall with how much power the laptop uses.

so ...the m17 can actually be starved of power and the m17x can more than likely run better with a few more watts at it's disposal...decisions...decisions....i know what i would do...lol

 

ummm, keep testing before doing anything drastic?

Could be something stupid like a crappy power strip I'm using outside.

 

but of course...

also...go ahead and pull one card out of the machine...that should answer your questions pretty damn quick. that's a 75 watt power drop alone.

 

easiest thing to do would be run power measurer with the 3870's stock then the 4850's stock

see the difference

 

I would imagine with that CPU cranked like that it is pulling down some serious power

Probably near 100W alone

 

killawatt meter is at work and I'm off of work for 2 weeks. Maybe I'll hit a hardware store tomorrow.

 

any decent meter should work to see. and what i would do is get your self a ac to dc inverter like we use for testing even the aries ones while not great would do a great job and not to bad price wise.

 

Can't find my kill-a-watt here, must be at my dorm. I remember testing my whitebook with it though when I had that, it maxed out the rating I believe with the QX9300 and 3870s. So the machine should be able to take at least that much juice. Again, next time I am at my dorm I will check on my desktop to see what my whitebook pulled from the socket

 

i thought you would work tommorw

 

Well it is the holidays coming up Moo, normal time for family men like Mandrake to take some time off

He can not spend EVERY night outside with his laptops while his family is watching movies

Although I am pretty dam eager to get outside in wyoming next week (lows in the single digits )

 

you can't max out the kill-o-watt meter with a laptop...lol
i have about 2200 watts going through mine right now..lol

and my d901c pushed it up to 310 watts. and that's when my stuttering started. the kind don was talking about in the other thread.

220 watt power supply maxed out at 310 watts...minus all that conversion loss stuff...which im sure someone will explain...
