Gainward Ti4600 GS : success

[JCviggen]

I had always been hesitant to mod this card since several ppl reported getting a dead card after a perfectly executed mod.

Today, inspired by macci's success, I took the plunge (albeit ghetto style with no soldering yet, just some scotch tape and a stiff wire ;)) and it works perfectly. i've been as far as 1.90Vgpu, but my cooling is somewhat inadequate :(

It'll do 391 at 1.88Vgpu and ice cold water with the 172W@24V. It doesnt make 398 (yet?) but I have only tested it for 30 minutes and did a 3Dmark run.

I only modded the GPU voltage (standard mod), since I can do about 800 on the memory anyway it didnt seem worth the risk (could change my mind soon ;))

Its damn hot around here today and I had to clock back my CPU even more. But i'll try and move a bit higher on the ORB in the morning. Also, I noticed I've never tried the "unlimited" cat, I think i'll give that a shot too :)

so anyone who has a Gainward Ti4600 and afraid to mod, I can tell you for sure that the GPU mod works like a charm

Good work my friend! :)
U run the tec at 24v!?
I thought that runing a 24v tec at 18 gives u best results :confused:
I think I have to run mine at 24v too to see what happens ;)

[JCviggen]

I can only choose between 14V and 24....

I got some water in the freezer for tomorrow morning ;)

How do you like the new siggy ? lol Courtesy of MrIcee :)

Cool !
I want one too :p

Hi
I have 2 vapochill. One make 1733@2112 at -14
The other vapochill have I mounted on my gainward.

before 320/740 after at -14 370/750

I need some more volt on the Gru

anyone have a link with some picture?

[Tom Holck]

OK
I found the pictures

Now i need the optimun values for the resistors?
to get ca 2.00 volt at the GRU
and some nice values for the mem

Congrats!

Looking forward to some new scores from you soon.:)

To get 2Vgpu you will need to set the VR to 450-500 ohms. 3Vmem will take about 1k ohms.

Make sure your cooling is working properly and don't fry anything.:)

Thanks Ddtung,

I tryied 500 ohm on the GRU voltmod, it could not post? Then worked by 1000-740 an then 670 ohm, a little better than 740. Now GRU can go 390-394 100% stabil no artifact at all.

The Volt mem could go 770 with 1000 ohm, at 740 ohm It can go almost 800...

I will soon post some Bench with my new XP2200+ that came today, just unlock the 5. on L3...

I ran close to 13000 DMark2001 SE on my locked (!) XP2100+
going 1733@1990 FSB only 153. It was a bad species. I have one that can go 1733@2112 on my Abit AT7 Raid voltmodded to 2.05 volt core. Vapochill

I use Gainwards OC software it can ONLY go to 400/800 anyone now software that can go higher?

Yes, Rivatuner, which can be downloaded @ www.guru3d.com can hit extremely high speeds. When it tells you to reboot, say no and make it detect your speeds now. If you have it already overclocked it'll think that your STOCK speed is your previous max overclock. So like you _could_ go to like 500/1000, but I don't think that'll be happening any day soon.

Do you guys think my this cross drilled copper block can handle a 172 watt peltier?

Right now I have an 80 watt at 12v there on my GF4 4.2k. But pumping the voltage slowly up to 2.1v does very little for overclock and its unable to break 345 mhz. Old core BTW.

2V Gpu is too much, it can do 400 mhz at 1.95V if cooled properly
