UX43VD Geforce GT 620M 64 bits !!

Hi guys,

I went from Asus UX32VD 3001v to 4002h. I also upgraded the HDD and put samsung 830 ssd with corsair CL11 8gb of ram to reach 10g. My pc is supposed to be more powerful that the one before. However, It seems the nvidia GPU is less powerful and i have doubt instead of putting a 128bits Geforce 620m in the 4002h they put a 64 bits (i could see it with Asus Gpu Tweak soft). Could someone verify it the 3001v has 64 bits Geforce aswell or confirm my expectation of a 128 bits one ?

Well, there's this for affirmation: GeForce GT 620M | Specifications | GeForce

From what I see, the 3001 has a 620M, which supports up to 128-bit bandwidth.

 

Thank you for that but for sure if i bother you to check it for me with a soft like GPU-z or asus gpu tweak it is because i want confirmation so that i can get reimbursed by Asus. A screen capture would be perfect.

I have a 4002 so supposed to have 128 bits but as you can see it is not the case. I feel less powerful video performance than my previous 3001 so just want to check it and see if i pointed it out well

 

Here is direct GPU-Z link for someone who would be nice to help me :

If I can get my hands on a working unit, I'll try to get a screen shot for you. Which CPU do you have? If you have an i5 or i7 (which I believe are the only options on the ux32vd) then you SHOULD have no problems with 128-bit support.

If your drivers are fully up to date and you are still encountering this, I would say: Contact Asus.

 

how does one know if its 3001 or 4002

oh ok looks like its a european model u have there, so cant verify for you

for the record mine is 64-bits but mine is the north american mode so i cannot really help u here.

but how are you positively sure that asus has ever offered a 128bit version in the first place for both 3001 and 4002? i mean, nvidia says "UP TO" 128bit but can also mean 64bit you know...

 

Hi,

I'm sure of it cause my video performances are less good than before however i have more powerful unit cause i went from 3001 to 4002 and did SSD and RAM replacement to improve it even more. Everything is smooth except my video performance (i'm using a video mixing soft). All drivers and codecs are exactly the same and i spent several but SEVERAL hours trying to tweak everything because i came to that conclusion

 

Do you need the 128 bit bandwidth for gaming? I would think you only need the wider memory bandwidth for engineering software. The clock speeds play a bigger role in performance for gaming.

"up to" 128 bits means that the card can alternate between 64-bit and 128-bit, also (as Chroma kind of pointed out).

But if you really want those 128 bits, then I would say look for a different NVidia driver, and/or see if the system board supports 128 bits. You may need to contact Asus for that info, and to see if there's a patch to allow for unlocking it so you can get past that bottleneck.

 

The 128 bits it's about the RAM speed. It can make a huge difference as with 128 bits it can treat 28,8 G/s vs 14,4G/s for 64 bits. In my software it had huge impact i can say it. Have a look at the link you sent me before they say it also that it can affect performance . I could verify it . It's not about drivers it is really the RAM which seems different

yes i read that too but it doesnt automatically assume that asus offers a 128bit card by default, and looks like you are trying to find proof that UX32VD did have a 128bit offering, if such a thing exists

but that said i think you will have a hard time convincing asus to reimburse you; nowhere did they guarantee or have an obligation that they will offer a 128bit version of the GT620M for UX32VD (though yes who doesnt want a better performance card)

 

I'm not there to be in a fight with them but just understand my position and how it was a bad suprise from going to :

Asus UX32vd Intel® Core™ i5-3317U Processor (3M Cache, up to 2.60 GHz) with hybrid 5400 rpm HDD and 4 go RAM

to

Asus UX32vd Intel® Core™ i7-3517U Processor (4M Cache, up to 3.00 GHz) with SSD samsung 830 and 10 go RAM

So when you observe a loss in graphic performance (playing and mixing two H264 1080p at the same time made my fps going from 60 fps before to 20-25fps now) you might be disapointed !

 

Which software is that?

"The 128-bit version of the GeForce GT 620M (with turbo) performs similarly to the older GeForce GT 540M due to their similar clock rates and core architecture. Therefore, modern and demanding games are playable in low to medium settings at 1366x768 pixel resolution. The rumored 64-bit version will likelysuffer from the reduced bandwidth and offer slower performance in comparison."

From their wording, it sounds like there is a 64-bit version of the 620M and a 128-bit version. Perhaps that's why NVidia's specifications on their site for the card state "up to" 128 bits.

 

is it just me or do i also see an upgrade in processor?

also, are you 100% sure you got your system to be in the exact condition, such as drivers and updates......and i dunno what kinda ram u added. i think its too early to jump and blame the video card

and what kind of footage do you have anyways that deserve a 60fps performance, taken with a high speed camera?

 

I went from R3001 to 4002 so the processor is i7 in 4002 vs i5 for the R3001.

I'm using Djing software call Serato video ( Serato.com | Serato creates world leading software for digital DJing). It can be downloaded here :

I tested with the clone settings regarding drivers version, soft version and video codecs. I also tried with different newer drivers as well cause i spent many days working on it to try to find a solution before caming to the conclusion that i don't see nothing else that could explain my fps is lower. The 60fps is the pipeline. When you process and mix 2 1080p videos it uses a lot of ressources of the GPU. If you get under 30 fps your video isn't smooth anymore. It becomes stuttering and slowed. In night clubs it's obvious to the eyes of the customers. Sometime it goes under 20 fps !! Before it was playing aroung 60 fps pipeline so no lag at all

 

Time to overclock the GPU?

 

I got my 32VD one week ago. I forgot were I found out it is the 64bit version. I just looked for an hour with utility apps and such. No luck in giving proof.

It is what it is. While looking for stats I overclocked for kicks. No rhym or reason to my OC but I pushed my 3DMark06 from 7600 to 8300.

Someone already said but to make clear 64bit vs 128bit is hardware limited not a driver issue. I also wonder if the 117 28nm lacking it's own port limits in any way. I have not had a working notebook or used Windows for over a year so still getting back in a groove.

 

Hi guys. Thanks for your help.

I figured out the problem. In fact I had written to asus who asked me an output with the soft speccy. I could see in it that my RAM was turning 1333 Mhz vs 1600 Mhz. This due to the Corsair 8gb RAM which was CL10 and not CL11. I made it replaced with a Transcend CL11 one and my FPS went up !!

 

The memory bus width will be determined the configuration of memory chips and detected by the bios. No amount of software can change it.

A 64bit DDR3 memory bus will hobble any dedicated chip these days.

 

So do you in fact have a 64-bi or 128-bitt dedicated GPU? And did your fps jump up to ~60?

 

I have little to offer to what might be by others described as a circular dsicusion. In the vain of moral hazard
I did get my 620 upto 9000 with the simplist of effort. MSI limits my clocks to 873Mhz and RAM 1150Mhz. I could push 1200Mhz RAM but artifacts. I don't want high scores I want stability.

What was the question again?

I get almost 7600 on 3DMark06 tweaked I am getting 9000.

Anyway that is all I have guys. Not sure 64 vs 128. I can't tell yet.

 

Hi,

I have a 64 bits GPU and think all the UX32 use 64 bits GPU and none of them use 128 bits. It is weird cause many tests on the net say that 1333 Mhz ram doesn't bring lots different than 1600 Mhz, however in my case it did ! I have around 20 fps more which is a lot !

 

Wow, that IS a lot! Even with the data rate difference in your memory, that's too bad that you have the 64-bit version card (although it sounds like you're not suffering a lot with the newfound increased performance).

By any chance, do you know your system bus? Sometimes that bottlenecks the DRAM, although you can overclock it to compensate.

 

I think apple produce only zenbook with the geforce 620m 64 bits card.........

Regarding my system but i don't know it.

Glad i solved my trouble anyway

 

Hi,

I'm coming again on that. Could someone install GPU-Z on its UX32VD and tell me if he has a 64 bits Geforce 620m ?

I have made many many many many tests and don't understand why my FPS is lower than before..........

For the record i had a UX32VD-3001v core i5 @1.7ghz, 500Go HDD and 4g RAM @1600 Mhz
now i have UX32VD-4002v core i7 @1.9ghz, SSD 256 go and 10g RAM @ 1600 Mhz (i also tried to put back the 4gig ram and hdd but didn't give me better results (lower)).

Their might be an explanation ?

Also with the 3001v i had to install Nvidia PowerMizer Manager (NVPMManagerUni-1.01.zip) and applied max performance and activated the overheat slowdown override so that i could have good performance. Otherwise after a few minutes the FPS would just drops. I think it was heat issues that perhaps had been improved in the 4002v ?!!!

Now really the only trail i have is that on the 3001v it is a 128bits GPU instead of 64 bits on 4002v

 

Hi,

I have a ux32vd-db71. I have 10GB RAM and Samsung 830 256 upgrades. Windows 8 Pro.

 

Thank you.

I forgot to precice that i would need someone with the i5 and non full HD screen. Cause i think it is the one with a 128 bits GPU

 

Your GPU is data starved so is using your system bus memory too so by increasing the speed of that you are getting a GPU speed boost too.

 

I didn't understand what you mean ? What can i do ?

I'm french speaker sorry

 

I was simply explaining why system memory frequency will be impacting your benchmark scores more than others, my 680M with its 256bit GDDR5 wont use that technique for instance.

 

ohh alright

 

You could see if faster memory would help, if you feel adventurous there are programs that can program your memory with high speeds, but there is risk involved if you don't do it properly.

 

I've been looking for this kind of program but never found it. Can you give me some names ?

At the same time with my old UX32VD-3001v i had less memory at same frequency but better perfs (i also tried to put back the original 4go RAM in the new one but nothing changed)
