hmmm id love to solder the gpu of my 9100 on my 8500 card! the 9100 does 330 without any mods on air but has some crappy ram. the 8500 only does 320 with vmods and watercooling :/
where do i get such a tool?

have u got 30K USD to start with :D?
is it that expensive? :(
i thougt maybe its just some kind of advanced solder iron... :D
Tnx guys. I'm quite surprised and glad to see that our humble efforts are appreciated by XS, the most hardcore ocing forum. It make us (me and my m8 La1kr0diZ) feel that we do the right things:)

Yes, we can solder GPU, NB, south bridge, CPU socket... Everything. Actually it is theoretically possible even to solder each detail to bare PCB and get working motherboard or vidcard, though it will be Xtremely hard (and senseless) task;)

We use... Mmm... I don't know if there is an adequate term for that equipment, but straight translation from Russian is "soldering station". It use hot air for soldering.

Do you have any ideas where to buy memory chips? We can't get anything less than 4 ns in stock in Ukraine:(
Delivery from another countries is not a problem, but we don't know where to find it.

Glad to see you here. U r probably nearest (geografically) XS member to Ukraine, by the way;)
We have Gainward FX5900 here and it is possible to use its memory if we could solder it back later (we've already soldered one chip back - when we mounted WB on core memory lost its massive heatsink and one of chips unsoldered from temperature (!). Of course it hasn't fall from card but FX didn't work until we fixed the problem).
But, there were 2.0 ns R9800Pro from PowerColor and they haven't shown something close to even 425-450MHz... R9800 has poor PCB design that limits memory overclocking (and also kills any advantages from DDR-II memory on 256Mb version BTW). So it is probably pointless to try to solder 2.2 ns chips from FX5900.
But if we could find any more 2.8 ns chip (at least one - we have 7 for now), then we'll solder them to La1kr0diZ's R9500NP. He's got 20700 with 430/302 clocks (crappy 3.6 Infineon), watercooled CPU and 240MHz HyperX, this week we'll try to break 21k with Vapo XE and GeiL PC4200;)... Then probably with 2.8 ns chips 430/400 (my Ti4600 worked on 385 mem without voltmodding) will be possible as well as 22-22.5k :)
There is one possible problem. AFAIK there are different BIOSes for different memory (3.6, 3.3 Hynix, 3.3 Infineon and so on) on 9500/9700. What is different in that BIOSes?
So if we solder 2.8 ns chips on card with 3.6 ns BIOS - what will happen? In other words - if u use wrong bios (not for your memory) on r9500/9700 what will happen then?
And one more question. I'm a little loosed in ATI cards line for now... Don't they have any R350-based card with R9700 PCB design? We could try to change GPU then, but we'll need a bios to get it work:)
Ive never (dared) to try this before.
I do have some hot air equip and a very steady hand if sombody wants to donate a card.
I have two dead TI4600 cards, one that definately has good memory if somebody in the UK wants to try a GF4TI upgrade.
If you supply a card ill try sticking my memory too it.
I might have a practice at work if im not too buisy, although I dont have a spare working card to try this on. (that I can afford to replace)
alt-f13, the sapphire (i think) radeon 9800se has the 9700pcb with r350 gpu. not sure if its sapphire, but there is definately a 9800se card that uses the 9700 pcb.
the diference in the bioses for cards with diferent memory is mainly memory timing and voltages, some memories need less or more voltage, not every memory chip is the same...
but since bge is pretty new i think they are all very close to the bga specs... try a bios editor if the card should not work correctly to change the latencies.
i would try to get the same memory that already is used ona 9700/9800card so you know it works and in case you cant edit the bios you can use the bios odf that card.
saaya, so what will happen if we solder the chips from another manufacturer. The card just wont POST?
The interesting thing is, hat will happen if we solder a gpu of 9800 to the 9700 pcb. Will it work as a 9800 se with a correct bios? We have good relationships with the guys in sappire, so i think we`ll be able to get a bare 9800 chip for that...
You guys are all nuts! :D
afaik it should work, the 350 on 9700 pcb i mean. the r350 is just a minor upgrade to the r300 gpu, the pins are probably all the same.
i dont know about what will happen if you use diferent memory, im not sure if all memory chips are pin compatible, maybe some memory chips have the same pins but in a diferent position , know what i mean?
i think all the memory chips are pin compatible bzut better check out the data sheets to be sure.
i think if you use a completely new memory chip for the card that it might crash and not run as high as it should because the timings are diferent ya know.
but actually i think theres a very high chance that you can take every ddr1 bga chip and solder it on the pcb without any problems. if you have good elations to sapphire ask them if they can buy some memory for you.
they can at least give them the right phone numbers and email addys to get some memory ;)
im sure if you tell them or their memory supplier about your fun project they will support you (if they are nice people).
saaya - video card ram is NOT cas3, and a hairdrier with some kind of directional vent on the front may work...
Mine is actually cas2 right now, and can be set to cas1 with the use of radedit 1.1.
I have a toast Ti4400 here with 2.8's on it.. they did 715mhz stock volts 8-)
Maybe I should break out the hairdryer and see if I cant pop them off just for the fun of it 8-)
ALT-F13 - the chip ns rating doesnt matter, nor make I dont believe. There are many radeon bioses out there and they pretty well all work with every card, as long as you dont use a herc bios on a card with dual ramdacs 8-)
STEvil, LOL. Why are there different bioses for samsung, infineon and hynix memory for radeon9500. Did you try yourself to swap em?
holst i have a semi-dead Ti4400 you can experiment on if u you like. I'm pretty sure it died cos some AS epoxy got stuck between the RAM feet. I then tried pull off the RAMsinks so i could RMA it, unfortunately i managed to pull one of the chips nearly out of the board :) . Its been sitting in a box for just over a yr now. I think the core is in good shape, RAM just needs replacing :) where r u in the UK?
ALT-F13:
As to buying Memory chips, you could try ordering directly from the manufacturer. It's probably expensive to order in small amounts though....
most card video memory runs cas3, radedit shows cl2 and cl1 but afaik those are just phantom options.
Just order them as samples, and make up a good sounding company name. I work for xerox so when i need chips i simply order free samples and national in particular send me any semiconductor they make free, they dont know its for personal use :)
Yes the soldering is achieved by a heat gun (available @ rswww.com for those in the uk) and solder, and a vacuum chip pickup device available from there too, but its by no means easy. A couple of guys at work do it on a regular basis, for work related pcbs.
Nice skills tho gentlemen.

Actually, I have tried a lot.. a couple around the time of the discovery of the 9500-9700 mod, and about 4 others in the last week working for a higher memory clock... none of them are getting me higher than 349, but thats still better than the original 9700np bios that got me ~320 and HOT chips.Quote:

There ARE bios's that will not work, but I haven't encountered any yet. Just stick to Mushu's and you'll be fine anyways.
Kewl, thanx. I`ll try the other bioses for my 9500. I dont want to flash the 9700 bios because the card wont show up as a 9500 in futuremark anymore, and i`ll end up with a not-too-bad overclocked 9700 instead of the world`s best 9500 :(
P.S. Wats "Mushu" ?
Mufu Bios, my bad.

Actually, you can flash to a 9700 bios and Futuremark will still show card as a 9500. It does with my Sapphire with 3.3 Infineon.Quote:

MUFU Bios is a custom bios made by....well..........MUFU. I just flashed my card yesterday, and am beginning testing. One of the member's here, MickeyMouse, has a Sapphire9500 with the same Infineon3.3. He said he got it to run at over 350mhz with this bios and voltmod's. I'm not having any luck yet but am still tweaking.
As for this amazing BGA re-soldering, very cool. How do you keep the other part's from de-soldering on the pcb? I would try what ]JR[ suggests to find replacement chip's.
Hynix has some 2ns BGA memory rated to do 500mhz.
http://www.hynix.com/datasheet/pdf/d...F(Rev.0.3).pdf
As far as bios'es to use on the modified memory cards. The different bios'es out there are in many cases specific to a particular memory. So just match the bios to the memory that you use on the card for starters.
I would use a 9700/9800 Pro bios.Quote:

The MUFU 9700Pro bios run's fine on my 9500 core and with the mem voltmod, there's no problem there either.
Damn, I wan't to try this, but cannot even see the pin's on a BGA chip. If possible, please post some pic's of the process:p:
The heat is directed at the component when doing single components.
Do r350 bios's work in r300's? I know I suggested this a while back and was pretty much told my card would die.. but the concept is interesting yet. Stuffing your old bios on a seperate boot disk with an autoexec.bat on it containing:
Would allow you to flash back to the old bios if the 9800 didnt work...Quote:
@echo off
cls
atiflash -f -p 0 oldbiosname.bin
WARNING: You do this and screw your card over, dont blame me!! 8-)
dont suggest u try that :) coz it's wrong :)
to save the bios its
atiflash -f -s 0 xxxxx.bin
Damn....some guys call me crazy when I am soldering my voltmods to my gfx-card, but you guys are soldering new memorychips to it! RESPECT! keep up the good work. I love this kind of topics ;)
He's not trying to save it. That is a script to re-flash the card in case of a bad flash. It saves you from the old PCI backup card.Quote:

btw SevEvil....
Wouldn't it be atiflash -p 0* ******.bin -f ?
humm , just an out of topic but i prefer to ask here than asking in a new thread
have you experiment any 9700 bios onto the 9500Pro one ?
actualy i'm with the 9500Pro infineon 3.3ns bios, and my rm won't go more than 310Mhz (if more then artefacts :()
Ok , i 'm done with my request , now , i can say :
WWWAAAAAOOOOOOHHHHH nice soldering man ! hope your 9500np project will succed :)
Well after testing the "MUFU" bios thoroughly I can say in my case, it hasn't made a difference. In fact it dropped my core clock 6mhz. So I was looking over at Rage3D and found this post by MUFU himself.
LMAO, not at MUFU, but how it all get's twisted.Quote:

The only change I made was to provide PAL and NTSC variations but any dumbass could have done that using RadEdit.
