yea now i just need to get my phase unit in order.... so i can get this e8600 up to par.... cant wait to start modding these things.!!11!!oneone!!!!

[STEvil]

Decided to go with the Asus EN8600GTTOP/HTDP/256. Hoping that 256mb of GDDR3 doesn't bottleneck me

Only hurts really in '03

Doing some digging it seems that GDDR3 clocks very good if your card has a decent VRM (which is why I chose the one I did)

The core and mem vrm's are always separate anyway... if you add a connector for external 12v you should be good to go

I've made my purchase - no giving the plot away Pieter

No worries

I'm looking to buy a card myself, but I'm not sure where yet. What DDR2 card has the lowers ns on the memory?

[Johnny Bravo]

The Zotac Gddr2 card was a good bet for faster memory I think

[dinos22]

damn it WHERE IS ANDY

[G H Z]

I guess I'll play, I need to test my new 8600's anyway

[SpikeP]

Well after much debate. i am going to order a ASUS 8600GT OC Gear, instead of the TOP. Just think i will go against the flow of TOP cards, and see how i fair

Was going to choose the Gainward 8600GT GLH, but the card costs nearly twice as much, and i wana go back to Ireland to see my girlfriend ASAP, lol. Decided i can wait a little longer though if it means im in this competiton!

Should be ready for action mid next week. Look forward to seeing everyones results!

I`m in Missed out on the fun last time. Looking for a card now.

[G.Foyle]

I'm definitely in! Time to look for a card...

Updated the roster. My card comes in on Monday, cannot wait to get started

Monday - you lucky to get it on laborday

Oh wait, yeah *doh* Tuesday

[TheGoat Eater]

I found a nice Zotac (for speed sake ... err time sake)

[dinos22]

did some testing

got gaymoda ICs on my card
'01 >> 850MHz
'03 >> 800MHz

cries

core on air does 663MHz linked for '03 and 700MHz for '01

roughly around 54K and 21K on air

gotta get someone to help out with the mods will post high res images soon

[oohms]

Ironically, the last 2 days i have been working has been the only time we were completely out of stock of 8600GT's

Hopefully there are some with hynix 2.5 or 2ns ram when we get them in

[dinos22]

here is my card

Xpertvision 8600GT DDR3 256MB

let me know if you can help out with core and ram vmods please

[TheGoat Eater]

nice PALiT - I am still trying t figure out which one -> if I go PALiT or get the Zotac I have been eyeing

[Moonman]

@dinos22

RT9259Ahttp://pdf1.alldatasheet.com/datashe...K/RT9259A.html
Measure resistance between PIN #4 and ground.
Resistance *20 = VR. Tune down for more voltage.

Pin 4 is the feedback pin for each of them. Measure resistance to ground and solder a VR ~20 times the resistance (set to max resistance first)

The left one is Vgpu and the right one is Vmem

interesting

so in future when i look for vmods i should look for Feedback Pin and do the same as you say there??

also Simon how do i know which one is for RAM and which for GPU? >>> just for future reference

[Moonman]

Jup, vmodding is so simple.
FB to ground resistance *20 for VR. Start with max resistance.

[tiborrr]

Blah, Moonman beats me to it, i already opened the datasheet for RT9259!

@Dino: Just measure the output voltage on the appropriate pin and you'll quickly know which regulator is the one you are looking for (Vgpu output voltage should be around ~ 1.2V, Vmem ~ 1.8-2V)

Just found the voltmods for the nVidia reference/Club3D 8500 & 8600GT:

[oohms]

the GPU vreg is usually beefier, on your card its the set closer to the top (all the caps and mosfets), so the RT9259A that's closer to that area is for Vgpu

Just find all the phase controller chips and yes, it is typically the feedback pin. Works for anything controlled by a standard phase controller. Just jump on google and start plugging in numbers that are on top of the chips, eventually you find the data sheet
