Dell :: D830 With T7300 Multiplier Issue
Feb 7, 2010
Laptops been working great for years.
Finally put Windows 7 x64 on the other day and I didn't notice at first but after a few weeks I started realizing the thing just isn't as fast for normal tasks as it used to be.
I remember I used to run speedswitch for XP back in the day and it maxed my CPU clock all the time. It obviously doesn't work for 7x64. So I loaded up CPUZID to check things out.
Basically the key reading is:
Current MHZ: 1595.54 Current Multiplier: 8x
Original MHZ: 2000 Origina Multiplier: 10x

I heve T9500 penryn processor with 2,60 GHz and the CPU-Z is showing sometimes 13.5x multiplier =2.7GHz (without any undervolting software or lite that)
The RMclock showing 14x multiplier like IDA and CPUgenie only 13x multiplier
what that means, Is it possible to have 2, 7 when it is only 2, 6 GHz?

I have a D630 running vista basic x64, 4gb ram, 500gb drive and currently have a T7300. On specs it seems like the T7300 07' & T6400 09' are basicly the same. I'd like to know if there is any reason to make a change since I have one available.

it came with 2gb of ddr2 ram ( 2 banks of 1gb)
i recently upgraded to 4gb
the pc knows it is there but only appears to recognise 3gb?

My aspire is as per topic title a 7720 T7300 (2.0ghz ,800mhz FSB , 4mb L2 cache)
I am running a recent Bios flash so up to 1.43 spec.
Is a CPU upgrade to a T9300...simple just a case of processor pull and new CPU refit?
Will it be of benefit or worthwhile in the firstplace?
As i can get a Intel®Core™2DuoMobile Processor T9300/2.5GHz/800MHz/6MB

My Envy has the i7-720QM processor. I noticed significant reduced performance when running on battery.
RealTemp, Sandra, i7Turbo, Intel turbo boost monitor, cpuid, etc.. all report the multiplier at 7 (~930MHz), and won't move from there no matter what I do on the machine.
The multiplier seems locked/fixed at 7 regardless of load. As soon as it is unplugged it dives to 7.
I've changed the power plan to high performance and set min/max power management to 100%. This made no difference.
Is the BIOS forcing this? I believe 7 is the low frequency multiplier but shouldn't this kick in only is there is no activity (to save power?). If I am doing work, I expect the processor to at least run at the minimum frequency specified.
This behavior has been confirmed now by other members of the forum. Previos BIOS releases (F.05 and F.06) have been tested and showed the same issue.
I attached two screenshots, one the system running on power, and the other one on battery. Both running prime95 small FFTs.

So for the past month or so, my D830 has been getting incredibly hot - something it has never done before. In fact, I used to 'brag' about how cool and quiet it was.
Now, about 20 - 30 minutes into computing, it's fans whirl at full speed and the entire bottom and right palm area get very, very, hot - even when the notebook is on a hard, flat surface.

The Dell D830 comes equipped with one powered USB port at the rear.
The powered USB port is compatible with USB 2.0 connector. When used with a powered USB connector that looks like a bloated RJ45, powered USB port can supply 5V (beige), 12V (blue), or 24V (red)..
They are color-coded and connectors are keyed to distinguish between them..

I'm getting headaches from my 1680 x 1050 display, it's a matte finish and has a very narrow viewing angle.
I run it at 1280 x 768 for best size and aspect, but it's then a bit fuzzy, too. Is it a reasonable change to go to a 1280 x 800 high-gloss display to get crisp text and wide viewing angle?

I had a D620 with the nvs120m, and I was very disappointed by graphics performance. I'm told the 140 is build off of an 8400, which should be much better than the 7300 the 120 is built off of. Also, my D620 had 64mb dedicated, and I'm told the D830 has 256mb dedicated. Does anyone who actually HAS the laptop have any input on how the thing handles games? I'm not expecting it to do well, but my D620 couldn't run anything even with the lowest setting on.

I'm starting to get some weird video symptoms on my Latitude D830 with the Nvidia Quadro NVS140M video. Fairly random at this point, maybe once or twice a week, the screen does something weird in terms of displaying stuff that it completely shouldn't, even during boot-up.
Don't know if this chip is a member of the family of Nvidia chips that suffers from the bugs, but has anyone else experienced this with a heavily-used Latitude D830 yet?
If I have to get a new motherboard, has Nvidia actually implemented a solution, or are they still shipping the same parts? I have ~3 years of warranty left (plus the bonus year), but I don't look forward to a motherboard replacement every year or so.

I've just bought a used Dell Latitude D830 (UK, XP SP2) and find the touchpad won't scroll. Otherwise pad, trackpoint and buttons all work ok.
I went into Control Panel assuming that the scroll areas weren't set up. Not so - unlike on my old C640, there are no separate Synaptics set-up tabs. Nothing - and it claims there's a Microsoft mouse plugged into PS2 .

Will the Dell Latitude D830 have any trouble supporting an Intel WiFi Link 5300 WLAN card?
I know its a generation newer than my laptop but the interface is the same so it should work without any issues, right?
Im basically looking for a wireless g stable, low power, wlan card that will work with this laptop and think the wifi link 5300 may fit the bill.

Dear All
I've been using Dell Inspiron for more than 3 years. It had a nice touchpad driver with which i could assign shortcuts to all the four corners of touchpad (e.g., Maximizing a window, minimizing, closing, and running a special application etc.). Now i m used to those shortcuts but they are not available in the new drivers of Dell Latitude D830, that i recently got. Can anybody point to the D830 touchpad driver having this facility or any free third party utility for that?
Thanks

i've recently purchased a 2nd hand dell D830 laptop. it was running windows vista and everything was working fine. but i need to have it running XP, so i formatted and installed XP PRO.
entered the service tag on support site, downloaded the "shipping" drivers. most of them install, some terminate with errors, others tell me that the hardware isn't found. no audio, also wrong display drivers, points me to intel drivers, but that doesn't install, nvidia one does the trick... just endless problems, but when i revert to VISTA, it all works again.
i need this machine to run xp.

I have owned a 10-month-old Latitude D830 (w/1680x1050 screen) for about 8 months now. It's a great machine, but I've decided to sell it in favour of something smaller.
Since I bought it, it has had a very small black speck on the screen that does not wipe away when cleaning it. To me it looks like dust behind the LCD surface rather than a dead pixel .....

my motherboard just crashed on me and I need to get a replacement for it and would like to catch two flies with one hit and upgrade my cpu while I`m at it but the d820 motherboard doesn`t support the better newer ones and i feel the d820 computer i own is still perfect for my needs.
Therefore I was thinking if the d830 motherboard has the same fit as the prior since after some looking into it they look very much alike but it would kinda suck if it didn`t fit.

I just got a new Dell Precision M4300 here in Israel (refurbished, not directly from Dell) with the following configuration:
CPU: Core 2 Extreme X9000
LCD: 15.4" WUXGA
Graphics: Quadro NVS 140M (apparently)
HDD: 160GB SATA 7200RPM
My question is as follows:
It in fact says Precision M4300 on the front of the laptop near the keyboard,
But when I turn it on it identifies itself as a Latitude D830.
I bought the laptop thinking I was getting a Quadro FX360M (it is CAD certified which is important to me as I work with their program).
What is going on? was I fooled in some way?
If I apply the latest M4300 BIOS update will it change the names of the laptop model and the graphics card?

does anybody know how to get the Windows 7 built-in screen brightness control to work with the D830?
Manual brightness control via FN+Up/Down works perfect, but Windows 7 does not offer software brightness control in energy options.
My second notebook (5 years old Toshiba) offers this (you will see a brightness slider when clicking on the battery/energy symbol in system tray).
As a result Windows is dimming (not turning off) the display automatically after a few minutes idle time.
System is Latidtude D830 with Intel onboard graphics and 1680x1050 screen

I've got an E6400 that got crushed and an almost unused D830. I want to cannibalize the E6400 and install it in 1.8 MHz 512 MB D830. I've zeroed the SSD, checked the processor and RAM and was wondering if it is possible to use a 1066 MHz FSB processor in an 800 FSB system,if it would recognize the 800 MHz memory and if there is a BIOS modification to allow the SSD to work to it's potential?

I have two Latitude D830 laptops.
They are mostly identical, but with two exceptions.
1. One has a but faster processor than the other.
2. One used shared memory for the video (Intel Driver) and the other has an nVidia Quadro video card with respective driver.
I would like to be able to swap the hard disks between the two computer.
My question is, can I install both sets of drivers and assume the respective computer will know what to do?

Windows 7 32-bit upgrade CD (not SP1), from XP. no anti-virus yet. Windows Updates current to SP1.I have always had my DELL mouse plugged in to rear port, but for unknown reasons it is now dead to all USB devices?
Mouse is now recognized by side USB port, but I like to keep them free for bulky flash drives..I tried uninstalling all ports/refresh from Device Manager, but rear port is still dead to all USB devices.I then tried a repair install from desktop, but still dead (1st time HD light flashed for 1sec, then nothing from then on).

Here's my story and, let's say, my analysis:
I bought a generic 2 HD sata2 RAID1 enclosure based on the chipset Silicon Image SteelVine 5744. It can be used in USB or eSATA2. This embedded chipset (named SiL5744) is known (understand "claimed") to auto-handle Sata I/II and host sata2 controllers that not support the port multiplier feature. The HD are two Samsung F1 1To. There's no jumper to rollback to SATA 1.5Go on them, you can only do it by flashing the HD's bios, however we don't need to do it as I wrote just before, the SiL5744 supports SATA 3Go natively.
The enclosure works pretty well with USB, but *not* in eSATA : the E6500 freezes/hangs just after the POST step (a potential driver issue with the installed vista 64bits is not the reason then). As soon has I disconnect the eSATA cable, the system recovers and continues as normal.
What I've tried/done so far :
Both E6500's BIOS SATA mode AHCI and IRRT mode were tested,
Intel Matrix driver and software was updated to the latest 8.7.0.1007 version (AHCI and IRRT),
The SiL5744 chip was upgraded to its latest firmware as well (in case of...)
In order to verify the esata cable, the HDs and the enclosure itself, I succeed to :
- Use the enclosure's RAID1 feature when using the USB connection, I could partition,format, and read/write on the logical volume
- directly connect *one* HD (Samsung F1 1To) to the E6500's esata port -(I have a sata2esata cable), Vista installed it and I was able to use it as normal, even the hotswap feature seemed to work fine (I unkindly removed it). I could so test both HD individually this way... On the enclosure hardware side, everything looks fine then.
An IMPORTANT thing : The E6500's ICH8/9-M sata host controller seems to support the Port Multiplier feature *ONLY* on sata port 0 -as a bubble message from the Intel Matrix soft sometimes shows up-, but this is exactly where the internal HD is plugged on the motherboard I found nowhere you can change the internal sata port ID (switch,bios,ect...). I think this is the key of the problem that seems to be a dumb port conflict, because the esata port is in fact the port sata 4 (the DVDRW drive is sata 1, dock's esata is 5 for instance). If somebody knows how to swap the sata port ID, I think I won't be toasted !

I'd like to replace the fan in my laptop (Dell's Latitude d830) with a faster/better one. From what I've seen, most people seem to think that this is impossible.
I, however, find this hard to believe that Dell would have included the only possible fan that's compatible with this laptop, or that this particular fan is the best possible cooling option.
Why is it so hard to upgrade in the first place? I'm sure it can be done, I've opened up my laptop a few times in the past and it's not exactly rocket science .....
