Something curious that I posted over at the UL30Jt site:
The Taiwan reviewer's of the UL30Jt GPU-Z info sheet on his 310M:
Taiwan Review of UL30Jt
UL30Jt GPU-Z
![]()
shows his 310M VRAM running at 667 MHz.
My U30Jc's 310M VRAM runs at 790 MHz. Why the difference?

So the UL30Vt 210M & U30Jc's 310M run faster VRAM (790 MHz vs 667 MHz), have more bandwidth (12.6 GB/s vs 10.7 GB/s) and more cores in operation (16 vs 8) than the UL30Jt's 310M.
Has ASUS done something to accommodate the increase from 512MB (U30Jc/UL30Vt) to 1GB VRAM (UL30Jt) on the 310M?
Opinions, anyone?
NOTE: As a comparison, here is the UL80Vt's 210M GPU-Z specs:

I don't see more cores in operation...
As with the memory speed, they probably got a nice deal on some slower memory. It's all about moneym so I guess that is the reason why the UL30Jt's 310M is a bit slower. -
"PCI-E 2.0 x16 @ x8"?
The U30Jc & UL80Vt have:
"PCI-E 2.0 x16 @ x16"
The 310M specs at NVIDIA list 16 CUDA cores. I assumed the x16 related to that.
What does it relate to?
And why the bandwidth difference? I thought (wrongly, it seems) that there were basic speeds & specs that each NVIDIA GPU had to adhere to such as core & memory speed?
Thanks. -
That figure would be the actual PCI-E bandwidth. Before I got things fixed up, my MSI GX640 would sometimes run with "PCI-E 2.0 x16 @ x1" instead of x16, which resulted in a 3DMark Vantage score of around 5k instead of 7k. However, x8 is easily enough PCI-E bandwidth for the 310M, so as long as it doesn't drop lower it wouldn't affect performance.
The memory bandwidth difference is a direct result of lower memory clock speed. Also, Nvidia's specs are the standard speeds for a given GPU, but it's not necessary to adhere to them. That's why there's factory overclocked and underclocked GPUs around. -
So would the lowered memory clock & therefore bandwidth affect/lower in-game game play & FPS in more demanding games like Batman: AA? -
-
Since the i5-520UM has Turbo Boost up to 1.6GHz, and up to 2.13GHz factoring in Turbo33, it definitely won't be the bottleneck for gaming.
I'm guessing they're using DDR3-1333 (for the lower cost), which is why it's running at 667MHz. -
-
In the US, the ASUS U30Jc comes with the i3-350M running at 2.26GHz on two cores (4 threads), but it has no overclockable Turbo or ASUS' Turbo33 modes.
In the US, the ASUS UL30Jt is supposed to come (not released here yet but has been released in Taiwan) with the i5-520UM processor running at stock mode of 1.06GHz, but with Turbo & ASUS' Turbo33 overclocks enabled, it can be boosted up to 2.14GHz for two cores or 2.4GHz on one core.
Is that what you wanted to know? -
Taiwan has the i5 version. -
Though there is one store (and only one store so far) in Canada that is selling the U30Jc with the i5-430M processor (2.26GHz and overclockable.) -
.
-
Seen in Portugal, is the i7 possible or is it a typo?

I am curious to see how the more powerful CPUs affect the battery life. -
-
Considering the 620M eats up 35W, any idea on the battery duration?
The gfx and hdd are still lacking..for the price tag of 1000 -
When my U30Jc with its i3-350M is running at 25W, my battery life is about 3 hrs. But it rarely runs at 25W unless I am watching a HD video or game, etc. (and even then, in graphic-intensive mode, it switches power off of the CPU and lets the discrete GPU eat the watts.) Under Office apps, it scales back to 1.2-1.5GHz max and its wattage scales down to 5.5-9.7W. Then, using integrated graphics, I get 8+ hrs., esp if I put it in "Quiet Office" or "Battery Saving" mode wherein it scales down to 913MHz and draws only 5.5W.
So I suppose it depends on how low the i7-620M can scale down as to how much battery life you can achieve.

double-post.

So I've been receiving this error whenever I would turn on my laptop. I tried updating drivers, reverting to old drivers and it still gives this error. Any help?
-
So not sure what your problem is except wrong or corrupted video drivers.
A few questions first.
Since the U30Jc has two GPU's running under Optimus, do you:
1) have the correct Optimus drivers for BOTH the Intel HD & NVIDIA 310M GPU?
2) Does ASUS even provide XP drivers for the U30Jc, especially for Optimus and the graphics chips?
Due to having Optimus, you can't just put in regular NVIDIA drivers for the 310M and the default XP drivers for this Intel (9500?) GPU.
3) Where did you get your XP graphics drivers from and
4) What version drivers are they? -
I'm running the Win 7 x64 that came with the laptop and the drivers I'm using are the ones from the Asus website. The Optimus driver I'm using is the latest one that came out a few days ago.
-
so is this laptop capeable of a user cpu upgrade ? (even though it voids warrenty?)
-
That would indicate that the driver you've installed for the Intel GPU is for XP, not Windows 7.
http://www.nvidia.com/object/optimus-win7-x64-notebook-189.79.html
I have NOT tried the latest 189.79 NVIDIA "Optimus" driver for the 310M. And with two GPU's, you need to be sure that the two drivers you're using work well together.
With this Intel GPU driver problem you're having, why not first try the latest Intel GPU driver V8.15.10.2102 & the NVIDIA GPU driver V8.16.11.8964 (189.64) (both dated April 13th) available on the ASUS site? The Optimus NVIDIA latest one may not be playing nicely with your Intel GPU driver.
http://support.asus.com/download/download.aspx?SLanguage=en-us
What are the version numbers of the two GPU drivers you are presently using? -
This might be of some interest to those who are still waiting on their machine and ordered from Amazon: I just had my order changed to "order shipping soon" and it would appear my card was billed. Shipping estimate is the 11th.

Does anyone know, because I am obviously too lazy to take the screws out, if there is room for expansion of RAM without having to replace one of the existing DIMMS? I presume not but wondered if anyone had looked.
-
-
as long as its not an integrated chip
-
Okay, Tech Friends, I have a problem.
I use Windows 7 64-bit HP on my U30Jc. My two GPU drivers are:
Intel GPU driver V8.15.10.2102 &
NVIDIA GPU driver V8.16.11.8979 (189.79)
working under Optimus.
I also have an external slim USB Blu-ray drive.
I've installed PowerDVD 9.0.2320 ULTRA, but I cannot get Optimus to run it using the NVIDIA GPU at all. With blu-ray, playback is choppy. While playing a DVD or Blu-ray, GPU-Z tells me it is using the Intel GPU, NOT the NVIDIA GPU.
This did this last night even under NVIDIA driver 189.64.
I have:
1) Updated the NVIDIA Optimus driver from 189.64 to 189.79
2) Set the default GPU in NVIDIA Control Panel (NCP) to be the NVIVDIA discrete graphics.
3) Added PowerDVD9.exe to play using the NVIVDIA discrete graphics under the NCP.
4) LAUNCHED the PowerDVD9 app by right-mouse clicking the shortcut and, in the context menu, select "Run with graphics processor"> "High Performance NVIDIA processor"
Yet it still insists on running it in integrated graphics mode.
This happens even if I play a regular DVD under PowerDVD 9 Ultra using the internal DVD drive.
Weird. As if Optimus has a mind of its own. ... or might this be a PowerDVD 9 Ultra issue under Windows 7 64-bit or with Optimus?
Any suggestions?Last edited by a moderator: May 8, 2015 -

I really wanted to buy this notebook....but the deal breaker is there is NO way to use an eSATA device (my choice for backup) - no Express Card slot, no combo eSATA/USB port. I instead ordered a Toshiba U500 with all the bells & whistles ... waiting for its arrival.
-
BUT, I don't know if the CPU is clipped in or secured more permanently. -
Can anyone else who owns a U30Jc and PowerDVD 9 Ultra test it with a DVD and see what GPU-Z says as to which GPU is being utilized? Thanks.
-
@Quatro:
I see two possible issues that could cause this kind of problem:
1) Optimus might not like it if an application isn't properly fullscreen
2) Optimus' profiling might not recognise the actual PowerDVD process properly
I think you should try viewing your movie with MPC-HC to see if you can get that to work with the discrete GPU. However, from AnandTech, -
I tried PDVD 9 Ultra in full-screen, but the stutter continues.
Optimus DID use the NVIDIA GPU under WinDVD 9 Plus (for BD) ... but WinDVD 9 also repeatedly crashes! So that's not working well either. Too bad, as the blu-ray discs play perfectly with no stutter under WinDVD 9 Plus. -
Which Intel GPU driver (version # found in Device Manager) are you using? -
-
When WinDVD 9 does it & uses the discrete GPU, it plays smoothly.
Funny thing is, it plays HULU (flash doing it?) with the NVIDIA GPU, no matter what I tell it to do. -

I wonder how they are deciding who to ship to? I just went over to Amazon's site. They don't even offer the U30Jc for sale now (from my bookmarked link) and if I do a search, the U30Jc doesn't even come up. -
-
I thought it would be as obvious as first come first serve, but they're following some strange logic that no one seems to understand. I wonder how they've managed to scrape enough U30JCs to even ship out since it doesn't even exist in their search anymore.
-
Thanks for the help but I fixed the problem. What I had to do was uninstall the Intel driver and reinstall using the drivers disk that was included.
Drivers I'm using now are:
Intel 8.15.10.2102
NVIDIA 310M 8.16.11.8964
NVIDIA Optimus 189.79 -
strange,, cant even search for a U30jc from amazon,
what is that usually mean? will be OOS for a long time ? -
-
Although, at the rate Asus has been delivering these to resellers, the "next batch" will probably be sometime in June.
