Help with memory benchmark

Aha, nicely found sgil, i'd estimate your ram like a 7.3-7.5

 

Windows estimates it at 5.9 and I would have to agree since I get frequent low memory warnings resulting in unbearable lags when running memory intensive apps.

 

you can also try Everest Ultimate memory benchmark which could show mem read/write/copy/latency, i found winsat data is lowest rate than all data of read/write/copy from Everest:

 

Posted an Everest Ultimate memory read test on the first page of this thread...

 

sorry i forgot that... what's your mem latency on this benchmark?

 

vostro1400user,

Looking at the Everest list in your second thumbnail, I see that my VAIO's raw scores are not too far off: 5262.05531 MB/s vs. the MSI with P8400 at 5496 MB/s.

Just curious as to why my WEI score is 'only' 5.9 with 8GB of RAM? The system seems responsive enough - PS CS4 opens in less than 10 seconds with fresh reboot (and no eBoostr running currently - actually not even installed).

 

It depends on the FSB setting--@311mhz it can be as low as 61ms, @stock267mhz it can be as high as 94 ms

 

I would look at the memory portion of the winsat xml code and try to find an imposed limit--outside of that I am baffled as to why your score would be 5.9 when others with lower bandwidth and lesser amount of memory score higher.

 

Already checked that (twice, after deleting and re-running the assessment again), but no limits are indicated.

This is just another 'benchmarks' don't work example for me!

But I am curious to see what is holding Win 7 back from giving it the 'proper' score (and, if it will make a noticeable difference in actual use too).

 

WEI is really weird, my vostro 1400 RAM get WEI 6.1 while vostro 1320 RAM only get WEI 6.0 (all shared memory with integrated intel video card), BUT the winsat data as well as everest ultimate benchmark in 1320 is much better than 1400:
vostro 1320 winsat:5247 MB/s; everest read/write/copy: 6230/5528/5330 MB/s
vostro 1400 winsat:4164 MB/s; everest read/write/copy: 5362/4208/4504 MB/s

 

vostro1400user,

Yeah, I'm not too worried about it (its not like I noticed a drastic drop in performance or anything)!

Just an update, (went back to double check I didn't miss anything in the xml code sgilmore62 suggested I look at) although when I type in cmd prompt winsat properties and it shows 7.96GB available, inside the mem.xml file, it says total Memory 8GB, available Memory 7GB.

Does this give a clue? Is the nVidia 9300M using a GB of system memory and 'robbing' some performance from the memory subsystem?

 

You can run this elevated command prompt and review the xml file...
winsat mem -mint 4.0 -maxt 12.0 -buffersize 32MB -xml memtest.xml

 

Okay, ran the above command (thanks sgilmore62) and after I tracked down the location it saved the file (had to move it to another folder to be able to read it though!) it now says 6GB available.

See:

PHP:

<Memory>
- <TotalPhysical>
  <Size>8GB</Size> 
  <Bytes>8555393024</Bytes> 
  </TotalPhysical>
- <AvailablePhysical>
  <Size>6GB</Size> 
  <Bytes>6888865792</Bytes>

 

IDK tiller, there has to be something about a limit somewhere in there no? You have plenty of RAM and a high bandwidth score compared to others with higher scores?

 

Just ran it again, no limits in the generated xml file.

 

I'm stumped tiller, and since I don't have access to your xml files probably not going to lose -- yeah, I'm gonna lose sleep over it...

 

lolololol....

sgilmore62,

I'm sure you'll sleep like a baby! But thanks very much for trying to track this down with me.

 

Here are my scores with my 4GB (Dell standard) 1333MHz CAS 9 I guess (FSB @ 1285 instead of stock 1066), NVidia chipset, W7 64Bits, 1 X GTX260M 1Gb, onboard 9400M 256Mb DISABLED in BIOS, Q9000 @ 2.4GHz.

Sorry for some french here and there, but I guess you guys get the picture anyways...

Interestingly, I did get 6.8 memory score with the FSB stock @ 1066MHz; and I do get 7.2 when overclocked 1285MHz, so WEI actually calculates (computes) the NUMBER of Operations that can be calculated in memory per second, NOT just the AMOUNT of avalaible RAM...

Hope this can be of any help !

 

If you enable the hybrid graphics in Alienware BIOS (I'm assuming you are on the discreet option) and rerun WEI assessment do you still get above 5.9? Toshiba Qosmio and Alienware M17X both have 9400m g chipset but Alienware M17x can disable 9400m g in BIOS by selecting discreet option in BIOS where Toshiba has elected to leave out advanced BIOS options. The 9400m takes 256mb of system memory when enabled putting the system at the less than 4gb of RAM on 64bit system -- limit score to 5.9.

 

Hey !

Yes, I still get above 5.9, as far as I remember, however, if I do that (enabling the onboard 9400M that do have INTEGRATED, DISCREET 256Mb ONBOARD, not shared from System's RAM, but which does share over 1GB of system's RAM ON TOP OF THE 256Mb integrated to the 9400M), well, I can't overclock my FSB to 1285Mz because it gets too hot in there and, while I could then cook some bacon&eggs on my keyboard, I get BSOD's, so it's useless.

So, basically, for me, it's not a god idea to enable the 9400M onboard because I then can't overclock as much as I do now, and overclocking the FSB also boosts RAM's speed, because it's the FSB that is overclocked, not the voltage nor the CPU's multiplier.

Again, from my understanding, WEI mesures the amount of data the system's RAM can handle, the NUMBER OF OPERATIONS PER SECOND the RAM can calculate, compute, which is obviously limited by the amount of RAM in the system, however, my very own common sense tells me that the speed the RAM works at might be more important to consider related as to how WEI mesures the effectiveness of the RAM.

Makes sense to you ?

 

In other words: If you overclock your FSB, will your WEI give you back a higher score than 5.9?

 

Your theory sounds good, but in practice it isn't borne out.

As sgilmore62 said, if video ram is giving you effectively less than 4GB of RAM, then the WEI score is capped at 5.9. With me, even with 8GB of RAM, running at close enough to other systems (about 5.3GB/s) I'm still capped at 5.9 WEI score. Other factors at play, overclocking notwithstanding.

 

Hi again !

There's absolutely no contradiction between what we all say.

1. WEI calculates how many operations per second one system's RAM can compute, enven MS states that, just besides the score.
   
2. The more RAM you got, the more operations per second the RAM can compute;
   
3. The fastest your RAM, the more operations per second the RAM can compute;
   
4. All in all, WEI's score regarding memory, because what is measured is the total operations per second the RAM can compute, the score therefore depends on how much AND on how fast one's RAM is.

Don't we agree ?

 

Wheres the catch

 

If Microsoft don't lie to uss, yes. I've also found this information now while researching. Confirmed!

 

lol, sorry, I had typed in my reply (soon after your post) and never hit submit! Duh!

Really quickly:

1. We agree!
2. We agree!
3. We agree!
4. We agree depending on the algorithm that the WEI scoring systems uses. This is the area/part where we disagree.


If I keep running winsat mem, my GB/s score goes lower and lower. I've made it hit less than 4GB/s (with a reboot, it can hit 5.5GB/s).

If I delete what is in the winsat folder (forcing Win 7 to recalculate the WEI scores), I can see that it benches at 3.9GB/s, yet my score is still 5.9.

If I delete again teh winsat folder, reboot and run the WEI assessment, I can see (in the xml files) that I hit 5.3 to 5.5 GB/s but the WEI scores still stay at 5.9. (See how this is frustrating? )

All the above, of course, with 8GB of RAM and 33MB 'reserved' for the system.

Now, I'll make sure I hit 'submit reply' this time!

 

does WinSAT from the command line actually update WEI without having a parameter like ... updateWEI?

maybe not? maybe you tried around all the time for nothing, tiller?

 

WEI memory =5.9 but bandwidth is more than doubled:

 

I upgraded to 6gb so now my score is no longer capped at 5.9 due to "less than 4096mb available to 64 bit OS". My memory bandwidth is about the same.
