fought with the camera, I think I got it this time... to clarify, it's either "L" or lower case "t"

You're right of course. The thing is, your board is different from the P5K/EPU. The Realtek audio chips are the same, but the supporting parts in the audio circuit are different components. That part is unlikely to be the same as the one @Robert B needs. Having looked at photo's elsewhere on the net, I have yet to find one that is high res enough to show the transistor in question, but I'm still reasonably certain that an A1P is the correct part.

 

[Robert B]

@xrror - thanks a lot for the picture and your help. Much appreciated! I have only one more request from you. Can you tell me the markings on those two transistors that I have circled? If they also are 42t then I might be on to something. There is no problem for me to solder another transistor if it is necessary.

@lexluthermiester - in the past I usually found clear pictures with stuff on ebay in some of the seller photos. In the case of the P5K/EPU I also wasn't able to find a clear picture of the whole area. I mean who would take high res pics of such an unimportant area. There is a 50/50 chance that 1p/A1p is the correct part as that is the conclusion that I also draw. We'll see.

Thanks for all your input guys!

I'm still not going to power up the board until I'm absolutely sure that I soldered the right part. I have an itchy finger but I won't scratch that itch for now. At the very least I'll remove the transistor and power up the board to see if she's at least alive as @kiriakost suggested. I got ahead of me and I jumped straight to soldering.

I'll also have to read some spec sheets to see what are the vital statistics of the 42t transistor and 1p transistor. More digging is required.

Also I looked at a couple of dead boards and I didn't find a 42t but I'll dig up more corpses from the organ donors inventory. I might get lucky.

I'll keep you posted have no worries.

So that seems to confirm what I've read that this board simply won't POST at 1600FSB. I kind a wanted to try an LGA771 Xeon E5472 (3GHz, 1600FSB, Harpertown core) in this board but after my research I decided to play it safe and stay 1333FSB. Honestly the capabilities of this system surprise me.....with a little tweaking it plays Metro Exodus, Far Cry 5/New Dawn, and Wolfenstein New Order just fine (30FPS is my acceptable standard - low budget gaming heh!) on my low resolution TV/monitor! A better video card like yours would be fun, as my card is quite low end.

The pinmod from 266 to 333 works on the $5 E7500 to get 3.67GHz 2 core. I've seen evidence of the 400fsb pinmod working on the Q9550 but only on X38 or X48 chipset machines that support the 400fsb. That mod is performed on a different pin. I have an Opti 380 X5470 swap and the E7500 mod outperforms it in single thread by about 10% at Geekbench. The only thing stopping the E7600 from being modded higher is lack of Voltage control which can be done by VID pimods also. You seem like the kind of guy who could pull off a VID hardmod if you wanted to.

@xrror - Can you tell me the markings on those two transistors that I have circled?

 

[Robert B]

@xrror Thanks a lot for the time you took to help me! Indeed that transistor is 42t - I'll have to remove the 1p/A1p. Good thing that I didn't power up the board yet.

 

[ThrashZone]

Interesting, the board I saw running 16GB had 4 matched JEDEC standard Hynix 4GB 2Rx8 PC3-10600U DIMMs. Odd that GSkill wouldn't work unless it was performance memory and needed more voltage or XMP timings?

OK, I read about that pin mod and wanted to try it but I'm too lazy to figure out which pin it would be on my LGA771 Xeon as it's rotated in the socket compared to a standard LGA775 CPU. If you try it and it works please let me know!!!!!

HI,
Pin mod did not work just kept restarting
But ek evo water block did work with the hyper 212 evo back plate and ek magnitude mounting screws lol they were the same thread as the 212 evo black plate holes
So yeah no pin mod but is water cooled so batting 500
Also scored a dirt cheap 980ti

 

[Retrorockit]

I had some Gskill DDR3 that was working just fine in my Opti 380.. 1 module failed so I returned the kit for a replacement and the new ones wouldn't run. Same part#. Apparently they switched from low density to high density at some point.
What pinmod did you try? There are only a couple CPUs where the stock Voltage is high enough to run the new speed.
Q6600 G0 stepping, and the E7500 are usually good going from 266 to 333fsb. But the 3Ghz Q6600 is slower than the Q9550/Q9650 CPUs.
As far as the Xeon goes. Look at the triangle in the corner, and mark the LGA775 notches on the CPU. Using those as a guide it's the same as theXeon then. But Xeons all start at 333fsb, so you would need an X38 or X48MB to try it, and it's a different pin.

Hi,
Must be on one page back
Here is another link

E8xxx/Q9xx0 FSB 1600 pin mod

E8xxx/Q9xx0 FSB 1600 pin mod QX9650 Retail http://www.coolaler.com.tw/coolalercbb/QX9650BOX/modfsb400/1.JPG Just put a tape on the pins... http://www.coolaler.com.tw/coolalercbb/QX9650BOX/modfsb400/2.JPG ...and off you go . http://www.coolaler.com.tw/coolalercbb/QX9650BOX/modfsb400/3.JPG...

[Retrorockit]

He's taping 2 pins but the one by the notch is already at 333fsb, just the 2nd pin from the notch should be needed to get 400fsb. But the MB chipset needs to support that speed. I see the E8xxx chips can go that fast on the stock 1.200V.
So add them to the list.
I just got a few E6500K in. Unlocked 65W LGA775. 266fsb on those so the pinmod will be first for 3.67GHz, then some multiplier overclocking on an Optiplex 380.
I working on an X38 Dell . I'll try the pinmod on the QX9650. Not sure if the stock Voltage will support it though.

 

[ThrashZone]

HI,
Yeah I really didn't expect it to work but saw the pin mod over two years ago and just never tried it until this morning

My suggestions they are expensive and I do not share them easily.

I'll keep you posted have no worries.

You better start a fresh topic because by hijacking this one of one transistor this is too much.

A guy I know was having a clear out, and decided to send me a little care package that he thought I'd be interested in...



I just need to test it all and see what is not working and what is I think.... Just thought I'd share some slightly older hardware

Good idea. New thread follows;

RobertB's Asus P5K/EPU missing transistor problem

This discussion became a bit much for the other thread so let's bring it here; @xrror Thanks a lot for the time you took to help me! :toast: Indeed that transistor is 42t - I'll have to remove the 1p/A1p. Good thing that I didn't power up the board yet. :) :rockout::peace: Not so fast @Robert...

Ohhh that dual socket MSI board!
Funky layout, 2nd CPU gets power straight from the main VRM and communicates directly with the 1st CPU, no dedicated RAM for it.
And I'm loving the GPUs! That Leadtek 8800GT is identical to my first ever GPU

 

[Dinnercore]

This one was looking for a new home, so I took it in:



DFI Lanparty JR X58-T3H6. Actually the first small formfactor board I own. Needs a bit of a clean in some places but otherwise in a good condition. Even the protective plastic is still on the NB sink and on the chip bottom left.

I don't want to give you false hope about the Xeon pinmod. The 333 to 400fsb pinmod is real, but the X38/X48 chipsets that support 400fsb DON'T support the LGA771 mod. So to do that you would need an LGA771 motherboard.

Lines up with what I've read about this board, 1600MHz FSB is a no-go, thanks for proving it for certain.

Bummer the X38/X48 don't support the LGA771 mod. And I doubt there is any LGA771 motherboards that can overclock other then the dual socket Intel Skulltrail board - and good luck with that $$$$$!

One of the other favorites that I have done in the past on good boards such as the Gigabyte EP45-DS3L is take a low powered Xeon L5430 (Harpertown 50W TDP) and set BIOS to run at 1600MHz FSB taking frequency from stock 2.67GHz to 3.2GHz. Not a crazy overclock but the FSB boost does help and the L5430 runs nice and cool at that overclocked frequency. I ran that combo for a years long ago, and should have never parted with it. But I'm happy with my current system considering how little money I have in it! It's running both Metro Exodus Sams Story and Dishonored 2 quite nicely as I play through them currently.

Nice haul!

I didn't think it was too bad as we swapped a few things and I gained a load more back than I was expecting !! Now I just need to find a place to put it all!!

He said there was a few motherboards and such that he had that he wanted rid of so I said, throw it all in a box, I'll give it a test and if it works, jobs a gooden! If not, I might consider sending it to @Robert B to work his magic on it....
I'm not sure when I'll be able to get it tested and tried out.. I have 'holiday' at the moment but trying to get an hour is somewhat difficult and I don't feel like trying to put things together during the evening/night when the children are asleep and I'm a little tired, that'll just lead to problems I think One day....

I'm pretty sure that 95% of those babies are still alive and kicking. We'll keep in touch if they might need some fixing.

I also found at the flea market a MS-6570 MSI K7N2 Delta L but even after extensive repairs, MOSFETS, capacitors, etc . it proved to be dead. In the pics is the board before surgey. After a stage 1 cleaning.

I know that overwhelming feeling when you already have a huge stash and new residents arrive in big number. You start to scratch your head and ask yourself where the heck am I'm going to put all of them? Don't worry you'll find a box/place to stash them.

Over the last two years my inventory has more than doubled and I'll have to do a thorough head count soon. I still have loads of space but sometimes I just watch at all those boxes with all their gems inside and I just know I'm past what it is the "normal" limit whichever it might be. The thing is that I consider that I don't have any problems myself so I keep gathering and fixing them one by one. I can stop any time I want I just choose not to. This is something above dedication it is a part of me. Each and one of us are addicted to something.

In the future I'll post an episode with the not so glamorous world of restoring PC components.
