Ti4200/4600 heatsink holes...???

[aca]

I'm planning on modding Kanie Hedgehog (http://www.tweaktown.com/imagebank/238m_1.jpg) copper heatsink and putting it instead of the stock one on the card.
Question: Could I use the 4 holes circled red on this picture (http://www.benchmark.co.yu/forum/attachment.php?attachmentid=8280) to hold the copper heatsink + 60mm Sunon fan (the stock cooler is using the 2 holes in green on the pic)?

Those 4 holes have a yellow metal "ring" around. I got some screws which probably could go through but if I use little force. :)
Can I do this? I mean could I damage the card like this?

Thanx!

I have got an ASUS Ti4600 card, with the exact same PCB (yours is an ASUS, right), and, duh, the same positioning of mounting holes... One thing I can say, that if you find screws small enough, you are not going do any damage to the card (not with mounting anything onto those holes, that is). Just be sure you don't bend/brake/scratch anything else on the card and evrything must be fine enough! :)

[EDIT]: If you don't damage the mounting holes (as in: damage the metal rounding) everything will be fine 100%

[aca]

@Vlad:

Thanx!

Actually that is a pic I found on the net. Here is the pic of my card. It is Asus V8420S Ti4200 with Samsung memory (3.3ns) & PCB from Ti4600.

Did you Vmod your Ti4600 card? Nice clocks! :)

[jumanji969]

I believe I remember reading that 4-40 screws should work through those holes.

[aca]

Tomorrow I'll go to the store with my card and get screws which will fit.

[DZVlad]

Those aren't my gaming-stable clocks. Those are open system 3DMark01 stable clocks :) I usually don't have the freqs higher than 305/700 as I prefer less noisier cooling to having a couple of fps more in some GTA:SA which still won't run higher than 20 fps @ 1280x1024 Very High :(
I'll have to get that room fan blowing onto my PC to get that high again.

Btw, what is the systen you are going to be benching the GF4 on?
I have got my AXP stable @ 200MHz FSB and I will try to beat my previous 15.111K with a clean Win2K setup. The problem is that the radiator I used for those benches is no longer on my card (i used those plastic things you can tie cables with, dunno how do you call them in english, to hold the radiator through the 2 stock-cooler holes). That radiator was a cut-out for a TT Volcano 6 Cu+, a rather bad cutout I must say. I'll see if I can find any photos of that lame setup I had a year ago :)

[aca]

u mean tie straps? :)

Here's what I got with this card last year on Intel w/ crappy O/C:
[copy/paste]
Pentium 4 3.0C@3347, Asus V8420 128 DDR, @325/690, 3DMarks01: 15546
I used Corsair 2x256 XMS pc3500C2 BH5 (forgot the timings I used).
I'm always on Win2k SP4. I hate WinXP!

If my Vmod goes OK, I'll use it on the rig from my sig, only after I set up the new watercooling system (still waiting for parts). This would be only for benching - temporarily to see how it does. Then It will go back where it came from.

Clocks 325/690 are ok for 3DMark, but in FarCry I get some artifacts.

[DZVlad]

lol, yeah, tie straps :)

Well, I DID manage to run those (330/730) clocks when I ran that 15.111 score. And your score would be identical if running on a WinXP, becasuse Win2K genererally gives you about 400 3DMarks (it gave me 350). But I'm using an SP0 Win2K distrib...

btw, what cooling do you achieve those freqs at?

I'll try to beat you in 3DMark01 (the 15.546 score) as I'm on 14885 now at 305/710 (and I already HAVE ARTIFACTS!! DAMN!! >:-()) and a 200x11.5 = 2300MHz AXP.

[DZVlad]

LOL, I have just found out WHY I get the artifacts at such low freqs! THe 80mm fan blowing straight onto my videocard stopped :( I'll have to fix that.

Btw, with the new system config using 200FSB (the 15111 was usng 189FSB) Already beats the 2365Mhz fsb 189 on 2300MHz FSB 200.

I won't push the CPU to the limit just yet, I'll see what I can get with a videcard overclock.

[aca]

I think I used only an 80mm fan blowing on the side of the card.
I'm off to the store to get those screws and some resistors and a diode for Vmod (I know it's saturday but...) :D

[DZVlad]

I have a crappy radiator on my core, so I need to cool it as good as I can. I managed to get 331/732 3Dmark stable with no artifacts (the previous time I did have artifacts). AS you can see, I have updated my sig, to show my new score :) I did manage to beat your score, only by some mere 200 points. And if you do a successful Vmod, I have no chanses :)

damn 3Dmark2001SE :) It never let me publish my 15.664 score (which is by far my own record) as it found "CPU frequency throttling" or some sort of BS. It is a known problem and it's even in FM's official 2001SE FAQ, but AAARRRGHH!!!! shlt happens, good it's only 2 points better :)

And one more thing. My GF Ti4600 ALWAYS shows as Ti 4800 :( The Win2K score only appears if you filter by Ti4800 and WinXP score (the previous one) Says Ti4800 in the project manager, but appears in the Ti4600 section of Search&Compare! :(

Is there any way to fix this bug? I don't want to be in the Ti4800 list, while having a Ti4600!!!

[aca]

:( Don't know about that bug. But it sux!
I don't have internet on my mail rig. Don't have room for a modem and IC7 doesn't have LAN on it. :( What I can do is get 1 USB wireless adapter for it and another for my other comp but I honestly don't feel like going through all that cr*p just for verifying my scores. :) That's why I can't verify my results. Although I got the 15546 score on one top 10 list.

BTW I couldn't find the right screws anywhere. :( Even took the card with me to try them if they would fot, but... :( One place they had the screws but did not have those other things... what're they called... don't know...

[DZVlad]

Although I got the 15546 score on one top 10 list.
What top ten list? As in Ti4600+P4s? now there are only 19kers on the first page of ORB.
I'm in the middle of the second page of Ti4600+AXP (which reads as a Duron(tm) nevertheless!) with my new score. But I think I won't even try going higher as I have no wish whatsoever doing any HW mods, though I might try giving a modded mobo BIOS a go, as there are lots of them for my motherboard. And trying to push my system further on air will have no luck as I know exactly what the capabilities of my system are.

I have a AXP 1600+ , ASUS A7V8X LAN mobo, GF3Ti200 lying somewhere around, I'll see if I can break my 9166 3DMarks record with that :) But that's when I have time. Now (as in the next couple of weeks) I need to have my main rig up and running prime-stable as I will be working on it. I have an idea on how to mount my Volcano 6 Cu+ in a more efficient than "tie-straps" way :) I'll just get a metal (or hard plastic) plank and mount it via the normal cool holes.

If you turn on your imagination, I'm pretty sure you will be able to use the standart mounting holes.

P.S. I think those are called nuts or screw-nuts.

too bad you can't publish your score, but can't you just save them and publish them on some other PC which does have internet access??

[DZVlad]

here are pics of how the stock cooling looked like, my record 3dm2k1 score - 15664 and a look of how my videocard cooling looks now

The place in my case is quite heavily cramped up with an Audigy Platinum eX and a TVTuner (that I don't use, but I have it in my PC nevertheless :) So there is little space for gfx cooling.

[aca]

What top ten list?
it's a list a friend made on one forum (from my country).

P.S. I think those are called nuts or screw-nuts.
yep! that's what I meant. :) can't always remember the word in english.

too bad you can't publish your score, but can't you just save them and publish them on some other PC which does have internet access??
if that's possible then excellent! I'll do just that. :)

[DZVlad]

Of course it's possible to upload your scores from another machine (but I think only in 3DMark2001SE, not 03 or 05 correct me if I'm wrong). You just save your project, transfer the file to the machine that you internet access on, install 3dmark onto that PC and there you go - uploaded score :)

[perry_78]

Nice to see your machine running vlad, its an interesting one :) In 03 and 05 you can do it as well, though in my case it's hit and miss. Clicking the area of the GUI where the score is supposed to show helps, if you opened and nothing uploaded.

edited after SA crashed on me.

[DZVlad]

Juliette, stop playing GTA:SA and pay attention to your typing mistakes! :)

I'll try finding the button in 3DM03, as I can't run 05 :)) Only on my laptop with GeForceFX 5200Go :)

[aca]

I just came back... again. Still can't find any smaller screws than 3x80mm. :(
Those 4 HS holes are about 2.5mm in diameter. Maybe I could make them bigger...
Also 80mm is short in length. I would need something like 2.5x200mm... and some screw nuts for them.

[DZVlad]

80mm isnt that short! how high is the radiator you are going to be using?

[aca]

80mm isnt that short! how high is the radiator you are going to be using?
It is short. It has to go through the pcb and heatsink (HS base is about 60mm), about 1mm is the gpu chip, and then there's the screw nut, and I would also like to put 2 small rubber rings on both sides of the board... so I don't damage it.

[DZVlad]

oh, the heatsink is 60mm.. In that case you are right, you will need at least 100mm for comfortable operation, but you can drill the heatsink to the base and the height will turn out 2-3 cms..

[aca]

sorry! my bad... I wanted to say the screw has to go through the HS base which is 6mm (not 60mm :D). So add: 6(HS)+3(~gpu chip+pcb)+2(nut)+4(2 rubber rings)=15mm

HS height is 40mm without the fan (from the base). Fan is 25mm.

[DZVlad]

Well, I was right! 80mm is enough! So the only thing you have to do is find the right screws! :)

[aca]

Don't know what's with me today!?!?
Must be the heat. All this time I thought u were talking 8mm, and not 8cm. :D
80mm would be too much. I'd go for 20-25mm. Because I just want to go through the base and end about 1cm from there. I don't need screws to go all the way through the HS or even the fan. The fan screws onto the HS with other screws. That's not a problem. :)

Look at this... 25 posts in this thread all about the dam* screws! LOL :D
I think at the end I'll use those tie straps. ;)

[DZVlad]

way to go with the straps :)

It was funny to hear that you were taking about 20cm :)) as you wrote 80mm and 200mm :))

And the 25 messages are not about screws,they are about mounting a heatsink onto a gfx card, LOL

[aca]

Finally found the screws+nuts. 2.5x25mm - perfect!!! :)
A neighbour gave them to me. Ha has a huge variety of sizes. Better than in those shops I've been to anyway.

In a day or two I'll get those elements (2 resistors and 1 powerful diode) and 60mm fan I need for the Vmod.

[ricercar]

Back in the day I used those four holes to mount an Athlon 462-style sink to a 4600. It was a reference sample that NVIDIA marketing had placed in the bad card box. That Athlon sink got the card working well enough to break 11K 3DMark01, and dependable enough to give to a non-technical friend.

Drilled holes in the aluminum to match the PCB holes. The screw heads went into the the sink, and the bolts went onto the back of the PCB over rubber grommets. Didn't place grommets on screws between sink and PCB. Used AC Silver5. I don't have the numbers for the screws; thought it was 4/40 nuts & bolts, but this size is too large to fit through the PCB of my only remaining 4x00.

G'luck

[aca]

@ricercar: Thanx!

I also meant to do these things "The screw heads went into the the sink, and the bolts went onto the back of the PCB over rubber grommets."

The screw number doesn't matter anymore. The 4 holes are 2.5mm in diameter, and so are my new screws. Only don't know how much they will stick out after I put the rubber grommets and bolts on the other side. But that really isn't important anyway. Screw length is 2.5cm.

I'll be using either Zalman grease (CSL 850) I got with my old ZM80D-HP vga cooler (sold it with 9800pro), or the grease I got with ThermalRight SP-94.
Which one do I use? There probably isn't any difference anyway... :)

[DZVlad]

you can give both a try, but I have heard some good responces about CSL-850 and have used it myself. If you have enough, you should try both! It might help for around 2-3*C i guess, because we are comparing good types of Tgrease.
I'm using russian thermal grease (yup, Russia does make some thermal grease) which is a bit better than CSL-850 (I have tried both and the russian one helps get 4*C on load from my AXP (see sig))
