First of all, I absolutely owe a big
”Thank you!” (although delayed) to all you who have posted replies with very valuable advices to my questions about how to choose parts for the ultimate 15” T60/T61/p UXGA FlexView/IPS ThinkPad. I don’t quite know what is happening, but sometime I do receive an e-mail notification from the Forum that a new post has appeared (in some thread I have posted a reply to), but often I don’t receive any (and, yes, I have
checked the ”Always notify me of replies” in my profile). Wonder what’s the reason for this? Anyway, now I’m all up to date on this thread!
There seems to be a general agreement that an integrated GPU is recommended (not surprising), to achieve the objectives discussed in my initial post (especially low fan-noise). However, in this relation, George raises a very important question: Whether an integrated GPU will actually also support UXGA?
Looking in the most recent ltwbook
(official title: ”Personal Systems Reference, Lenovo ThinkPad Notebooks, 2005 to present – withdrawn, November 2008 - Version 348”) and seeing which integrated GPU’s are (/was) available in 4:3 (non-widescreen) T61’s I only find the ”Intel Graphics Media Accelerator X3100 (GMA X3100)” listed. It is used in T61’s having either XGA or SXGA+ resolution LCD’s (and is also in the wide-screen T61’s running WXGA and WXGA+). According to the Intel GM965 datasheet
the X3100 is said to: ”Supports a QXGA maximum resolution (2048 x 1536) @ 60 Hz, 32-bpp” so this kind of indicate that UXGA with at least 60 Hz should also be supported... but who know if Lenovo both implemented the drives and also enabled support for this in the BIOS? I have tried to find the answer to this in a bunch of IBM T61 Announcement Letters
, but no luck…
According to System service parts - ThinkPad T61, T61p 14.1inch standard screen
there only seems to be one single motherboard using this GPU, being the FRU = 42W7648
– so the question now simply is this:
Will this Intel Graphics Media Accelerator X3100 (GMA X3100) actually support an internal UXGA LCD? If not, not much fun in getting this mobo and trying to get it to drive a 15” UXGA FlexView/IPS? ! So, anybody would happen to know the answer to this: GMA + UXGA = go
Whether mobo’s with NVIDIA GPU’s should be avoided or not (potential reliability issues?), that’s however a bit unclear, to me, but since NVIDIA’s are all discrete, and we want integrated, this issue solves itself!
What exactly is ”Intel AMT”? (Intel Active Management Technology - iAMT)… anything I need or want? (if I even have a choice?)
What CPU is recommended?? (wanting the muscles, for peak-power applications, but also and even more wanting it to be quiet and low-noise under idle/light use). This question perhaps more or less answer itself… the T61’s coming with GMA/X3100 according to the ltwbook
support (at least) T5270, T7100, T7300, T7500. The newer T8100 & T8300 seems to require 14.1 wide-screen mobo’s with the PM965
(as what I have been able to detect from the ltwbook
and various announcement letters). On the other hand, some T61u
(yes, ”T61u” whatever the ”u” means?) also uses the GM/PM965 chipset and support both T8300 and T9300!! According to the Personal Systems Reference - Intel PC Processors, December 2008 - Version 349
both the e.g. T7300, T7500 (page 7) and the T8300 and T9300 (page 8 ) are ”Socket P/Micro Flip-Chip Pin Grid Array (Micro-FCPGA) requires 479-pin surface mount Zero Insertion Force (ZIF) socket (mPGA479M socket) or Micro Flip-Chip Ball Grid Array (Micro-FCBGA) for surface mount (479-ball)” and are all supported by the ”Mobile Intel 965 Express Chipset family” – and all are 800 MHz FSB and 35 W TDP so this could seem
to indicate that a 14.1” GM965 motherboard will actually work with Penryn T8300/T9300’s (and perhaps even T9500) – does anybody know whether this hold true or not??
Stay away from T61 mobo’s at all?? This advice comes from dr_st
, and is interesting, although a few more detailed reference as to why
would have been appreciated! But, surely, a T7600 (667 MHz FSB) would probably only run slightly slower (at max. speed) compared to e.g. the T8300/T9300 (800 MHz FSB)... but even if choosing to go the T60-GMA route, the same question as asked above stands: Will the T60-GMA support an internal UXGA LCD??
Subsequent update to the above:
According to the thread WTB and FS
) T60's with the GMA 950 "seems" to be support UXGA on the internal LCD, although a solid, definite confirmation to this has still not been found.
The most quiet fan?? I also can’t figure out the answer to this; if, say, T61 fans are a generation more quiet compared to T60 fans, then this would be a good reason to lean towards a T61-based machine. I should add that a recent ”for sales” thread on the Marketplace in this forum holds quite some interesting information on this very subject: FS: Loaded Custom T61p with UXGA Flexview
In that thread, describing this T61p, freddy418 wrote:

About the T61p fan there, it was asked:
Would you mind to elaborate (the more, the better!) what is actually being said in red here:
...Intel T8300 CPU with T61P Fan and Heatsink (quiet)??
Does your fan e.g. never run or does is only run under heavy CPU and/or GPU load, and in any case what exactly does "quiet" mean? I am potentially interested, but I am very (very!) picky to noise, and in my vocabulary "quiet" meas "no noise" = fan always off (under light use)! Does this hold true?
.. and this was the reply:
I am defining Quiet in this context as much more so than the T60P fan, which is an automatic headache inducer. "Quiet" also means in a competition with hard drive noise, the fan produces less.
… which seems to indicate that a T61p discrete fan is very quiet?
Replace the mechanical HDD by a no-noise SSD? Absolutely tempting; absolutely the way to go (costly, of course, but…), and this once again emphasizes the question: Which model is most low-noise; a T60-mobo w/T60 fan or a T61-mobo w/T61 fan? I really can’t answer this, as the only T6x fans I have heard is one in a 2007-QPG
(T7200 w/discrete 128 MB PCIe ATI Radeon X1400). That fan (FRU 41W6407, ”Thermal device and fan - Discrete”) is certainly audible, even at lowest speed. I would absolutely be unhappy to have my ultimate ThinkPad arrive with that fan inside!
OK, enough questions for now! I started off this thread a while ago in one
American way, and since back then things have happened, and the World has changed, so if anybody would ask me today if my Forum friends and I are able to see this project through to a success, I’d surely say: Yes, we can!
Thanks in advance if anybody can shed light on the above questions!
I just noticed that this is my post no. 1000 on this forum, and although I have learned a few things since my post no. 1 I have surely also learned that there is much
I still need to learn to become a true, expert-ThinkPad’der!
