*OFFICIAL* M17x Benchmark Thread - Part 3

A 1920x1200 run only adds about 3C-4C. I'm sure it would hit mid 90s easily in xtreme burn mode though. I don't even bother with that mode since I haven't come across a single game that ever pushes the GPU's like that.

 

word, I had some on my GPUs and this was on my cooler with the fan set to high(if you can call it that lol), so this is what you can expect if you applied it.



Uploaded with ImageShack.us

room temp was 79F. Took a few minutes for the fans to kick on high.

 

I'm hitting 106° in Furmark at 640x480 in Stability mode. I'm OC'd to 750/1100. I even have a laptop cooler with a 120mm fan that my laptop always sits on. How are you guys only hitting 80°?

 

WOW! That is an incredibly high temperature. Something is not right with your cards/system

 

Another thing I noticed is that my average FPS is way higher than any of the other screen shots. Like my cards are rendering more FPS, therefore working harder.

 

Yeah but you shouldn't be pushing them to that high of temperatures. You could boil water and then some with those temps

 

Looks like an older version. Get the newer 1.8 release.

 

the 100+C temps are the ram temperatures, not the GPU core temps

 

I got the newer version and now I'm sitting at 100°C. Maybe I need to turn that OC down to stock.

 

@lozz
No that's definitely gpu

 

ORLY? have you ever opened up AMDGPU tool where it acutaly has descriptions for the probes? Have you ever seen how poorly the GDDR5 in the 5870's is covered up? Or how big the gap pads are?

 

The air coming out of the vents is very hot, indicating that there's good heat transfer. The cooling system is doing it's job. This thing could use some better thermal grease and probably needs the clocks backed down to stock. Like Lozz said a few pages ago, Furmark is worst case scenario. Nothing will really get them that hot.

 

Well gee when you put it that way why did I even comment

 

well let me guess. those guys run air conditioning too. even for my own M17X i notice too much difference because weather conditions changed dramatically during the latest weeks and i dont have air condition.

all notebook coolers only slightly reduce temps when talking about benchmarking conditions. thus if they are connected to usb they may also increase the system temp a little bit while they also reduce it at the same time or they may reduce stability at those extreme benchmarking tests.

 

you're not going to increase temps while running some sub 500ma fans on the port, that's nonsense. That being said, I do use a notebook cooler and so did joker, they're definitely not by any means designed to cool well, but it does make a big difference still. I connect mine via an A/C adapter, just so I can run the 4.5V fans on 6V to get a few more rpms.

 

i thought they would burn if increase the volts. anyway i didnt know this can be done. i am searching for an A/C adapter for the cryo NZXT. is there anywhere to buy?

 

the Cryo comes with a 5V 2000ma adaptor. I just use a universal 500ma one I got @ bestbuy. over-volting anything will decrease life expediency, but not dramatically unless you really crank it, and I only ever do it while benchmarking. The cryo NZXT uses a 2amp PSU, which is a lot... if you can find a 6V 2amp PSU you could use it for some extra kick, but I would just replace the 120mm fans with faster ones since the 5V PSU it uses is huge anyway. 2000ma is enough for three of these

and that's a combined cf/m of 330.

 

all those look like chinese. as i dont live in US i cant order from newegg. i just need an ac to usb adapter? if you could recommnd me something from ebay it would be nice.

 

Do you have any old AC adapters laying around? I tend to collect junk, so I had one from an old set of computer speakers. You'll have to do some simple splicing though.

 

nothing that fits the cryo NZXT really. i think i found something

http://cgi.ebay.com/EURO-AC-DC-Powe...tem&pt=LH_DefaultDomain_2&hash=item1c13e71677

it says 5V 2000mA

does it fit the nzxt?

 

OD: 3.5 mm
ID: 1.1 mm


that's the size of the plug, you'll have to do some searching to find out the plug size on the NXZT.

the power output limit on a USB2.0 port is 500ma, so you *have* to use the AC adapter if you want to run the fans at the high setting.

 

ok i took the ruler. i think its exactly the nzxt dc input dimensions. but i cant find the dimensions officially anywhere

 

The best way would to look at the adapter on the newegg page or try to find a picture of it online and attempt to look up the official specifications of the adapter to see if it has the dimensions of the plug. I'd check real quick for you but newegg isn't working for me atm.

 

newegg site works for me. i dont see newegg has the official dc adapter as a part. specs for the adapter itself are the same as i can see from the pics.

http://www.newegg.com/Product/Image...er w/ 3 120mm adjustable fans Model CRYO-001B

however i cant see them describing the dc adapter diameter anwhere . if you can search for it too it would be appreciated

 

What I am thinking of doing is making a battery pack for my Cryo so it does not have to plug into either the wall or the laptop. And then it can charge off either of those. Probably wont happen though, would be a pain to make.

The fans are regular 12v 120mm case fans so they can take a higher voltage, it is the power circuitry between the plug and the fans that may be limiting.

 

There is a thread concerning the cryo lx and the M17x
http://forum.notebookreview.com/alienware/408831-m17x-cryo-lx-3.html

The current thread is for benchmarking

 

obviously and the other thread is one years old which means that most dont have the adapter as it came with the cryo nzxt long after.

 

Yea guys please keep it on topic.

 

To get back ON topic....anyone know any registry tweaks for ATI drivers to boost performance?

 

there's a bunch you can do with rivatuner, but it's been so long since I used them they probably don't work anymore, or I wouldn't know where to modify the .inf files..

 

what are you up to now..mr cook?

 

I am just fishing for ideas to boost performance. Seemed like the next logical place to go

 

that or see what else you can put in there to bench....
in your position...i would start finding other cpus that will work in there...to bad the 3870s dont fit or do they?

 

Please stay on-topic in this thread, thank you.

 

well I just pretty much confirmed the 4GB DDR1333 samsung modules Dell uses are just maxing out @ ~1560mhz... using 1 module at a time I can get an extra 4mhz FSB and take it to 1600mhz but it's still not stable getting there. Are there memory timing programs that work the R2? If I could loosen them up a bit I'm sure they have more, CAS 9 @ 1600mhz is asking a lot, even @ 1.7V.

 

cpu tweaker might work for you.
Tweakers.fr

give it a try

 

awsome, thanks, Can't change CAS, but can change everything else, which is better than nothing.

 

if you can change the first one in the bios that would be super.
if not
then run a:
7-8-7-18 thru 27 and 59 thru 88
7-8-8-18 thru 27 and 59 thru 88
8-8-8-20 thru 27 and 59 thru 88
8-9-8-20 thru 27 and 59 thru 88
8-9-9-20 thru 27 and 59 thru 88
9-9-9-24 thru 27 and 59 thru 88
9-10-9-24 thru 27 and 59 thru 88
9-10-10-24 thru 27 and 59 thru 88

this should help loosen it up for over clocking ram higher.

 

I tried shifting it to 11 and 28 with a 2T rate and it did absolutely squat. Either 1600 is just it's absolute maximum with CAS 9 or there's something else going on that's giving me the brick wall. Granted it was on both sticks, but if a 2T command shift and 2 extra timing didn't even give me another 4 mhz with 1.7V... :/

disappointing to say the least, as well as since a lot of times just setting the registers 'too quickly' locks the system.

there are no ram timing adjustments in the M17X BIOS, and the CAS timing is not adjustable with the utility you provided. The one time I managed to get a linpak out of 160mhz it was actually 1GFLOPs lower than 156mhz lol..

 

what did you change?
and what version is yours

 

ras to cas, ras precharge, and command rate I believe. I think I changed cycle time but I can't remember. I could probably get a little more with CAS 10 but it probably wouldn't be much anyway if I get 0 more with a 2T command rate.

 

The Cas has to be set at system boot. That is why it cannot be manipulated from Windows (without a restart if you do manage it)

The BIOS determines an appropriate Cas latency based on the JDEC settings for your ram. If I boot at 1066 FSB/Ram the ram will be cas 6, at 1333 it goes to cas 7. I would not expect to get better than Cas 9 at 1600 on standard dimms. If you buy some performance ram, MAYBE but even then. My desktop has top of class performance ram and it is DDR3-1600 Cas 8 (the cas 6 or 7 stuff is about $200/2GB).

If high speed ram is a concern of yours, try playing with the 1600 hyperx stuff (even though it uses nasty XMP the ram is at least rated that high)

 

you should be able to change just those and leave the it at 1t
check my prior post

refresh may need to be 88 or even higher than that.

side note:
i got 75.4 points so far scook9

 

it's the latest they had avaliable for download in the link provided.

the Samsung Modules Dell gave me has is set to CAS 9 @ 685mhz but has no presets past that. Since i'm overclocking using setfsb, it wouldn't change it to accommodate FSB during boot anyway. I'll just have to buy some kingston modules later on I suppose

 

but it doesn't mean you get better performance...this is good in some case while in others..it's better to go lower cas. and if the ram is that flexable, then it's not hindering anyones over clock...that's for sure.

also looking at it..you may need like 1.75 to 1.80V to hold a low cas....(speculation of course)
and those codecs are guidelines for the most part.....

 

If I can't change the CAS value then the only course of action would be to upgrade the ram to something that can handle it better so that I can up the FSB some more which will give me better performance. I doubt another .05V or .1 V will make a difference. .2V over stock does absolutely nothing. Either way it's frustrating since It's just a guessing game mostly in this system using a BIOS that's restricted this much. It could be the ram, or it could be the PSU, or the Gap Pad that's not making great contact with the mofsets, or the 3 phase power system, or the fact that it doesn't look like it locks the PCIe bus..

the kingston ram is ratted @ CAS7 @ DDR1333, so if all else fails I can run it lower. I'm not sure I'll buy it though, the M17x just isn't fun to overclock, and then what's the point?

 

I'm glad everyone has given up benching, gives me more of a fair chance when I start up my machine once I'm back from my travelling. Heyoooooo

 

The futuremark servers were down for more than a week Is why I'm guessing there haven't been any developments.

 

I have just been benching other laptops we got lying around to get more hwbot points haha

Will get back on the M17x shortly to get my 01, 03, and Vantage scores up. Then I will see if the M17x can accept a T7200 (667 FSB) and bench that some (assuming it does not hose my motherboard)

 

I havn't even begun. I think tommorrow I'm going to set up my benching 40GB Intel SSD. Just saw your location and I met a beautiful Aussie girl recently in London. Love the accent
