R52 15" Intel XGA -> SXGA+ Question

[dcfbf]

I have an R52 1860-CAU which is a 15" with intel graphics that was originally optioned with an XGA panel. (currently shelved to avoid southbridge failure. I'll fashion some sort of a copper heatsink out of a 100x100x1mm copper plate in the future)

I'm thinking of swapping in an IDTech N150P3-L01 into it, an SXGA+ IPS panel.

I have found all of the parts I need, SXGA+ cable, the display panel itself, and the inverter for a pretty good price on eBay. ~$40 total(tax+shipping included). I was about to purchase all those parts until some last minute researching brought me to this thread: viewtopic.php?t=70813

Another thing to consider: R52 units came with a couple of different Intel-based boards. Only the ones that were originally enabled to support SXGA+ LCDs will do so. And the one that OP has acquired doesn't seem to belong in that group...

Does this mean that this upgrade will not work even with the correct trio of cable+inverter+display?


(Yes I was the one who asked which R5x series to get. Ended up getting an Intel R52 model to avoid the ATI GPU failing since I was told it could support SXGA+, but depending on the replies to this post, I may be regretting my decision.)

AFAIK all R52 with Intel graphics can do SXGA+ (but 15" only).

What is the FRU (or P/N) of your R52 motherboard?
R52 was available with 3 Intel-chip versions on it: 910GM, 910GML and 915GM.
Don't know about the 910GM, but 910GML and 915GM definitely do SXGA+.
Ex-factory your 1860-CAU had 915GM and FRU 39T5648 or 39T5558.
So unless the mobo was replaced with an incompatible one, you should be good to go.
Once you have the new LCD installed, read also this.

Thanks and also, what would be a good Southbridge temperature to aim for when I make the heatsink? Right now, it is at 43C according to tpfancontrol. Though I do have my wlan card disabled.

Pursuant to the adage to use the Forum search, I've attempted to find anything else about quantifiable Temperatures of the Southbridge, but superficially nothing numerical appeared. search.php?keywords=t43+southbridge+temperature&x=0&y=0

From the reports of other Forum members like kzfhu, generally just putting a heatsink on the Southbridge is effective to keep it going and the riskiest point of failure shifts to the GPU. You're already taking steps in the right direction by disabling the WLAN and installing a heatsink. Well done.

I am as a matter of coincidence also taking delivery of a T43, albeit with Intel GPU, in the coming days. I'll be removing the WLAN card and will probably YOLO it from there out.

I installed it! It works!



I can see that it's a bit yellowed but for a $15 panel, it's not that bad!

It does ghost a bit though, is that normal or am I missing something?
