Since the P8600 is a fairly common CPU on the XPS Studio 13/16 I thought this would be worth posting.
Stability was confirmed at each FID with Orthos for 60 minutes. I chose to disable SuperLFM and IDA. Under 100% load, at 2.4GHz the reported CPU temp dropped almost 12 degrees C. Obviously the difference was less at reduced speeds, but still worthwhile.
I do not notice any difference in the way the computer responds or performs, so as far as I am concerned this is free cooling. I was able to get 4hr 15min on the 9-cell battery with screen brightness @ 30% and low CPU demand (IE8 with wifi) so it probably modestly improves battery life too.
-Fan isn't on as much as with A09, not running on lower speed when cooling is unnecessary -Still downclocking!! Though it seems weird because the GPU doesn't go over 81c even with OC @ 600/900/1590.
Besides that all is good actually.
I installed all other new updates etc. also HDD firmware for the seagate.....there is still a weird latency problem that's picked up by dcp latency checker but for me that doesn't give any audible problems (not even when producing music
should I buy the Dell XPS 1640 (P8600, ATI 3670). I intend to use the Dell XPS 1640 for web surfing, watching movies, and play some light games online. Would my Dell XPS 1640 with ATI 3670 will have these problems like overheating and throttling?
After reading those horrible stories about XPS 1640 like overheatinga and throttling). I am not so sure about buying them.
Image you're using your notebook for things like 3D CAD, photo and video editing and of course for travelling. For my purpose I think the M2400 with its 14,1" monitor should fit perfectly. The perfect combination between mobility and performance.
Now I have to decide between 2 processors. As you know the P8600 isn't available and even Dell couldn't tell me if it will be available in the next weeks.
As you know the M2400 can only be ordered with the following processors:P8600 (2,4 GHz, 25W, 3MB Cache)T9400 (2,53 GHz, 35W, 6MB Cache)
So which one would you choose and why? The price difference is about 100$ (71,4 EUR).
Running IntelBurnTest at the highest setting for 5 times, on my HP Laptop with a T9400-2.53ghz it causes the temps to go to 105 degrees which is the max temp and this causes an automatic downclock to 1.6Ghz for sometime. System is stable though. Also the times increase for each run meaning as the system gets hotter the clock downgrade to 1.6ghz is more frequent in each sucessive run.
how to overclock the P8600 processor but had no good luck, I know I can't overlclock through the BIOS, but I've heard of using programs such as SETFSB, but I don't know how exactly how I can use this program for my processor specifically. Does anyone know how to overclock my processor P8600 (1006 Mhz)
Here is some additional information:
DELL STUDIO XPS 16 Intel Core 2 Duo Processor P8600 : 2.4GHz/1066MHz FSB/3MB Cache 1GB ATI Mobility Radeon HD 4670 Video Card 4GB OF DDR3 RAM
If there is any other information that you need please ask, I would really like to overclock make it to 2.8 Ghz or
I finally got what is the old school Generation 2 look which IMO looks better. click here if you're interested to see how it looks like. Custom parts include the slot load DVD, keyboard, Atheros card and seagate hard drive. Future plans include quadro card sticker (being mailed) and maybe an internal camera mod.
After assembling everything, I continued to do more benchmarking using 3dmark05 and overclocking under vista. I've heard stories about vista hurting performance, but my god does it murder a good amount of framerates and performance. Non-overclocked, I got a best of 8582 on XP, and 7749 under vista.
After reflashing the vid bios and playing with rivatuner and atitools, I started at 575 core and 650 mem, ran 3dmark05, scored 9320. At first, I was pretty amazed at the score considered what vista did to it when it wasn't overclocked. I thought it would go somewhere where it was under XP (non overclocked). Anywho, I decided to up it a bit to 600 core and 700 mem. This time, 3dmark05 gave me a 9110. I tried it again, this time turning off any programs running in the background, and got a similar score. I lowered both clocks back to what it was when i scored the 9320 and ran it again. This time, it gave me an 8840.
Pretty interesting how these scores came about, but has anyone been in a similar situation? I'm thinking about going back to XP or just make a double partition for it, once i figure out how to w/o wiping half my HD.
I've been attempting to undervolt my laptop following this guide The "Undervolting" Guide
Using RmClock, I reduced the voltages to the minimum and ran Orthos for 12 hours.. without a crash... It seems sort of wierd being able to reduce the voltages to the lowest amount allowed for all of the multipliers,
In looking to pick up a laptop and have it in my hands by late next week, I found that I had to go with the 2.26 GHz processor from the P-series. I was hoping for 2.4 GHz or better.
The reason I was willing to do so was that the notebook is coming equipped with an OCZ Vertex SSD at 120 GB.
My take is that the hard drive is still the bottleneck, so a mere 140 MHz difference in the presence of an SSD isn't going to be felt, and that a 2.4 GHz processor + SSD isn't going to really be snappier compared to a 2.26 GHz one with an SSD for most things.
Done some testing of chargers and charge rates. My non scientific findings as follows.
Battery start capacity 91.3%.
After 19 minute charge time -
Using 70watt charger :
Off 98% On low power 98% On full power 97%
Using 30watt charger :
Off 98% On low power 97.5% On full power 94.5%
To conclude the larger charger mostly maintains charge rate regardless of load on the computer.
The standard 30w charger maintains its charge rate on normal use, yet go to 100% CPU and charge rate drops by around 50%. It possible this could be far worse with an external USB HDD attached, 3G dongle and so on.
It seems that the computer can consume a little more than the 30w charger can output, but only of use in extreme circumstances.
Even with a larger charger the charge rate may drop if you had the computer consuming excessive levels of power, not sure what point this may occur.
Additionally batterymon charge rate indicator did not support the real world test.
I've browsed the discussions and have seen problems similar to, but not exactly the same as, my problem, hence the new thread.
Problem: I have a brand new Inspiron 1545 from Dell online. When I type text in Internet Explorer (e.g. webmail applications or this forum), even at a relatively slow speed, many of the keys don't seem to register --
that is, letters or spaces whose keys I press do not show up on the screen. As a result, I must type verrry slowly to make sure that every letter/space shows up, or else go back to re-type it. Strangely, I do not have this problem when typing text in, say, Notepad .....
I have an Inspiron 17R SE 7720 and ti works great however when I plug it into an external monitor LG W300H the resolution displayed is quite low. I try to choose a higher one but there are no options for higher resolutions. It's actually quite a bit lower than the resolution displayed on the laptops own screen.
I want to undervolt my Presicion M4400 as per this guide: The "Undervolting" Guide
A few questions as I embark!
1) Does it matter how much power my M4400 draws when I do this? That is if I later attach USB drives, add a 2nd hardrive to optical bay, should I take these into account? I assume no but just checking.
2) After doing the first stress test I got max temps of 76C on CPU, after lowering the max 10.0 multiplier voltage and running it for 10 min I got max temps of 79C. Something must be wrong?
In RMClock's CPU info page (see pic. 1) the "current" 10.0x multiplier reads 1.1250V when Im doing the stress test although I've set the 10.0 multiplier to 1.1500V (default max is 1.2500V) on the profile page (see pic 2).
Shouldn't the read outs correspond with the set max voltage? Also on the RMClock CPU info page (see pic. 1) the "maximal" 10.0x readout is 1.2500V which is again different from the set 1.1500V.
Is this normal or have the setting not been saved or something?
3) On the advanced CPU settings page my thermal monitoring is not checked (see pic 3) this differs from the Undervolting guide screenshots and is not specified if these should be on?
