Vostro 1400 overclocking, its crazy.

Good stuff! Considering the temperatures you measured were of the heatsink, it's quite probable that 90-100C under load is a correct reading for others. You also had the laptop sideways, increasing airflow compared to having it lie flat on a surface and the cover was removed, further helping temperatures.

 

More good news everyone, this is directly from an NVIDIA rep...

"The GeForce 8400M GS graphics card has been tested up to 145C core temp. The normal temperature of these GPUs will be like 65 -70C under load in a 72F / 40C environment. I request you to please contact your laptop manufacturer for exact temperature details about your graphics card."

Sounds like we have some headroom in the temperature department as well...

@Manzi - I'll have the Bioshock results for you Wednesday.

 

Hmm... I find it curious that my readings from various programs still seem higher than most peoples. It could be my configuration and other system components that are contributing to the high temperature. I borrowed my friends 1420 today and the chipset temperature ran on average 5-8 degrees celcius lower than my own but it could just be that I'm running the 2.2ghz. I'm glad someone finally got a thermometer reading though . I may have to get my own to test, unless someone else with the same config as my computer also is getting similar temperatures (that seem to higher than most of the other ppl posting here)

 

I saw this come up within the forum. Quick question, and an answer (or a definitive opinion) would be greatly appreciated!

Is the 8400m gs in the Vostro 1400 gddr2 or gddr3?

As far as I can tell, the facts seem to point that it's gddr3;

1.) The m1330 uses gddr3, Dell would cut costs by using the same component in both rather than having two slightly different components, hence two different items to *attempt* to always keep in stock.

2.) The clocking on this forum is outrageous! I believe gddr3 is 9.6GB/s = 9600MB/s = 8(bus width in bytes) * 1200Mhz(mem clock). As I have found in another forum. So some of your clocks on the memory are close to a 750 * 2 = 1500Mhz clock.

Am I right to assume this is gddr3?

DISCLAIMER:

*My reason for this insanity: I had a 1520, but found it too large. I want a graphics card that can come close to the 8600m gt (gddr2) in a 14.1" (and affordable ie. under $1500) Perhaps if this 8400m gs on the Vostro 1400 has gddr3, I can overclock it reaching speeds close to the 8600m gt I once had *

 

The card should both be GDDR3, although until someone looks at the model number on the chips themselves, we can't know for certain. The clocks people are hitting (800MHz+) would indicate GDDR3.

You may get to 8600M GT memory bandwidth levels, but there's just too much shader power that you can't make up for. You may get to ~2/3rd or possible 75% of the 8600M GT's (DDR2 version) stock performance but not much more than that.

 

come on man, look at the model of the chips, i already dismantled my 1520, and you've already dismantled youre 1400, what under there???

 

Interestingly, my 1500 is the same as yours (400/400 defaults). And, I tried 600/750, and within 30 seconds of applying the setting, and just sitting at the desktop, my XP just crashed and burned...

Apparently, the 1400 uses a different 8400GS than the 1500?

 

3dmark 3795 I'm using ATI tool to keep my notebook from downclocking. I also see 107 max temp using rivatuner. Without overclocking, it runs 104 max temp...really bad

 

Considering the Vostro 1400 can overclock the 8400M GS RAM at amazing speeds, yet the Vostro 1500 cannot get past 500 on the MEM speed, but the CORE on both can get to at least 600 and further, doesn't it seem that the 1500 is possibly using GDDR2 and the 1400 is using GDDR3?

 

That's an interesting take lancorp.

Is it safe to assume that what the Nvidia rep said above a couple posts, would also carry over to the Nvidia Quadro 135M in D630 laptops? (i.e. core temp could get to 145 deg. Celcius?)
