Ive just been using normall solder to put the chips back on, I think ill get a much higher success rate using liquid solder.
Ive only tested on dead cards so far, but ive got the tequnique down pretty good.
if anybody else in the UK has a potential ram donor or a card missing a ram chip can you PM me as I need some more patients (victims)
I dont want to try any upgrades just yet as it would be a shame to kill a working card (I dont want the blame) but If I can get a few succesfull repairs done ill try some upgrades (my 9700NP needs better ram)
Hehe, this is fun.
I presume this technique would work on BGA modules on memory? I have KingMAX TinyBGA PC3200 that I'd be willing to swap with you Holst for some decent RAM ;)
Nice work ALT-F13. I stuck a bit about this thread on the front page about a week ago. Looking forwards to more pics and to see the card up and running!

What type of memory was the 380mhz clock? And the new 400-402mhz?Quote:

Can you tell me how hot your oven is?
Nothing else de-soldered doing it? Seem's like the cap's would blow up or somethinghttp://forums.unrealplayground.com/i...eadscratch.gif

well with BGA u cant even get to the soldering pads with normal soldering iron :D?Quote:

as least tsop u can use remove it easily a special clamp style soldering iron
Thats the hard bit, getting the clamp style soldering iron 8-)
With an oven or heat gun you just heat up the chips and pull them off, heh.
YOU'RE DA MAN ALT-F13 if we can call modd to anything that's DA THING :)
Ok, guys, 2.5ns are already on my 9500np. Check dis out

Its not working even 600 rite now but i hope changing bios would help. Also the memory is underpowered because 3.6 used to work at less voltage. I`ll do both mem voltmods and try making some results.
Looks schweet!!!
what speed had the Ram you had on this card before?
Where did you got these 2,5 ns chips from?
Are there some photos from the mountingprocess ?
QT
There are photos of the mounting on previous pages of this thread.
It had 3,6 Infineon before. Now it has Hynix 2.5 taken from FX5600 ultra...
Yeah i saw them, but more aren't bad.
You had also used this grabber? Or a different device ?
QT
The same one, though these were soldered back using the heat gun not the oven.
Hope you dont have any so called cold joints, that would be crap :|
looking @ your mods im thinking of ordering these DDRII 1.6ghz chips from samsung and mounting them on my 5800 nu ;]
that's crazy man, good luck with overclocking them chips :)
DAmn, Only If we could make the perfect combo. Raddy 9800 with high clocks, put together with some Great RAM ns. We'd hit the top of the orb!
Oh by the way when you solder it back in, (the other chip of memory) How do you know which way it goes etc?
now this is one xtreme mod, gotta keep updated on this.
wow it works? :eek:
YOU DA MAN La1kr0diZ! :toast:
where did you get that heatgun from? how high did you get the 2.5ns chips on the 5600u with how much volts?
how many pins do the bga chips have btw?
how hot did you get the card more or less to get the chips off? and how did you get them on again? same thing? put them on and heat it up or something else?
I think they have 186 balls from memory.
I heated them and lifted them up with a bit of aluminium I bent into shape.
The hard bit is getting the solder even onto the PCB or chip, ive not yet fould a good way of doing this. I think liquid solder will be the answer but I havent tried it that way yet.
I held the chip in pliers and heated it till it stuck back on. This isnt ideal but I have a steady hand, I can probably make a jig to hold the chip in place if I was going to do more.
I took a chip off of and onto a 4200 last week, but I dont think id be able to do 8 in a row untill I sort out the solder.
wow, id love to do this...
I've got an almost dead FX5900 card with 2.8ns modules on.
My guess is one of the memory modules are dead or something. During post the card work, but there are some vertical lines with diffrent colors.
This happend after a faulty vmem mod.
I guess some of the modules are fine... and the core... So if someone is interested..?
Vertical lines are certainly a memory chip burnt. You can replace the chip to get it back to work.
Should just solder on socket clips for the ram then you can get ram with pins and change it at will...
Would be nice on a GPU, too 8-)
How does yours have 2.8? They are supposed to have 2.2.Quote:

Unless yours is the value or "lite" version.
True, it is a LX version (Leadtek Winfast)Quote:

I have a question for you guys... I have an R9700pro that i pushed too far.. I now have the verticle lines syndrome apon boot up, you can see some of the screen, but for the most part, pushing the voltage too high on the mem burned something out (prob the mem chip). How can one tell which chip it is, if he were going to replace it? Second question, who can tell me where to buy the chip, 3rd question, who wants to do it for me eheh..
