Overclocking ASUS N6600

[LOE]

It seems I got a good card - it runs 430/640 with no mods. But I am a little unsure about temp readings. The asus smart doctor reports very low temps - about 50 C at full load. Is this real or the app is misreading temperature.

Also I seem to have very low 2001 score - 11000 at 300/550 and 12500 at 420/620 - maybe the GF6xxx ain't good for 2001. On 2003 it scores about 6100 overclocked with 1.8 Ghz tbred.

Any ideas of temp readings and low 2001 score, I need to know more info before I push it to the limit.

[Micutzu]

Temps are OK, 3dm03 score is OK, 2k1 score is CPU limited.

[BOBO]

Whats happens when you go over 430Mhz on the core ? does it freze ? :confused:

[BOBO]

well? :stick:

[LOE]

yeah it freezes

no artifacts or sign of instability, just freezes

[BOBO]

Does that mean it needs more Vcore or just a better powersuply? :confused:

[Nosfer@tu]

I just goot that card yesterday.

Anyone know the Vmod for it?

[LOE]

WELL the PSU is 400W, it shouldn't be a problem... as for more volts and a volt mod... right now I don't have the time for such activities

[BOBO]

I just goot that card yesterday.

How high can you overclock urs ? :confused:

[BOBO]

Its funny cause my cousin bought the same exact card 2 days ago without consulting me(he knows i know sh1tloads about this) now hes stuck with a 0.11micron 6600 that O/C's less than most 0.15 micron 9800Pros'!! i would have told him to get a Leadtek one but its too late now, anyways his memz arent too bad, they good for 675Mhz before acting up, its the core that wont O/C verry well, it hardlocks at anything over 427Mhz wich is just sad for somin 0.11 micron, most other 6600's are able to hit 500 with ease and way more too, so whats the deal with these ASUS cards,are they proggramed to O/C to 430Mhz and hardlock or somin, is it a safety meassure? cause ive seen lots of cases were people hit the same 430Mhz wall with theyre ASUS 6600
We are really good friends and hes a bit sad about all this and it would be cool if i could make his work at 500Mhz on the core just like a GT, would anyone know how to do that?
Thanx in advanced :toast:

im experiencing the same thing but above 550 with my albatron 6600u, its really enoying!
what ram is on your cards?
mine has 2.8ns bga type :p

[BOBO]

6600u? Ultra? :confused:

[xs64]

6600u? Ultra? :confused:
Yep , Albatron have a 6600 Ultra , just higher Core/Mem than 6600GT

:rolleyes:

[BOBO]

How can it be higher clocked than a normal GT when it only has 2.8ns DDR1 instead of 2.0ns DDR3 ? :confused:

My bad , it just clocked higher than a 6600 standard :D

[BOBO]

You can clkock the core upto 550Mhz? :eek: :eek: , mine cant even do 430Mhz*cries*

[Snowman89]

yeah it comes 350/700 stock and i can run 550/780 in 3dmark etc, now its really really hot here, for 2weeks ago i benched 1 run with 560 on core only in nature to se how it would score.

[bullit]

if you want to make a safe overclock in your gpu try this :downloads.guru3d.com/download.php?det=815 (http://downloads.guru3d.com/download.php?det=815)

[LOE]

OCking 6600 isn't dangerous... but the card has a limit at about 440 Mhz, it needs more volts, so a volt mod is welcome :)

[BOBO]

Why does the ASUS 6600 O/C so badly :( :( :( , my "old" 9800 Pro would run at 440Mhz all day long how is it possible that with POS CARD being 50% smaller in micronage and all only be stable upto 420Mhz on the core :( :( :(
Someone please tell me how to unlock its potencial :(

[computer_geek]

my sparkle 6600 agp is at 450core 680mem cant go any higher either with no mods

[BOBO]

How can that be tho ? :confused:

[computer_geek]

how can what be bobo??

[jhatfie]

I have a unmodded Asus N6600 (AGP) and it clocks to a fairly decent 500/710. It performs about on par or slightly better (except 01) than my old 9800 pro that was OC'd. I did a few runs with it a while back on my backup machine (A64 3000+ @ 2.3ghz) 3dMark05: 3088, 3dMark03: 7297, 3dMark01: 17217. Should do better with some fooling, but have not gotten around to it yet.

[Mahoney]

man! 500 mhz on your asus N6600 agp? :confused:

i´m on stock 1,29 Volts for gpu and theres no way to reach 450 mhz

but im getting some sweet mem clocks.

okay... artifacts starts at 770 mhz..
but im still on stock volts (2,6) .

at 2,7 V i guess that crapp will disapear. need to work out a vmem mod.

[jhatfie]

Yeah, I originally had some trouble overclocking it over the 450mhz mark. Then I modded the bios to enable to 6600gt temp monitoring trick and fooled with it a little more and poof, got it up to 500mhz. I only run it at 475/675 on a daily basis though.

[KingYubbo]

Geez, that's some impressive clocks.

I got a Xpertvision 6600 with stock everything.
It runs 443/660 with my 2600+ Barton and i get 6100 3d03 marks.
I can put it up to 445/695 before it craps out.

Currently running 440/680 with only the stock heatsink and no direct airflow.

Does the modded BIOS work for all the 6600's?

do you have 1.29v in 3dmode?
i mean if you run 3dmark03 and checked voltage is it still 1.29?
my card has 1.325v as windows voltage and 1.375 as 3dvoltage

are u measuring voltajes with software or via pcb + tester :p ?

with my tester ...I was on 1,29 at windows. and during 3dmark 01s2 it still was on 1,29 V

i´ll check again that later.

[computer_geek]

ok i just ran black hawk down for a while and my temps got to 78oC max is this the norm for these 6600 agp cards

[computer_geek]

got higher again 720 mem 450 core
6495 3d03 marks
89oC

[KingYubbo]

How do you guys get your clocks so high? You guys running stock volts?
What drivers you using?

My Highest with 77.72's and a Barton 2600+ @ stock.

Those are such nice score, better than GT in fact! ur so lucky urs has 2.8ns and 1.375Vcore, mine only has 3.6ns and 1.29Vcore *cries*

ok.

datasheet

http://www.anpec.com.tw/products/download/APW/Apw7063/APW7063.htm

Vmod for gpu on ASUS N6600 agp is the pin 4 ( FB =feedback ) on the (Synchronous Buck PWM Controller ) APW7063

http://img286.imageshack.us/img286/6121/20050330asus3yo.jpg

http://img316.imageshack.us/img316/3326/apw7063pin9so.jpg

just solder a 10 K ohm Vr to that pin and the other lead in the vr to ground. you can use pin 6 (gnd) of that same ic or a gnd from the molex conector that he card has.

first set the VR at maximum 10 K and turn it down to gain volts.

you can check the vgpu at a cap lead near a small ic at the back of the card,.

BTW, Thank's for your advice Zakelwe :) :toast: :buddies:

Could you please post ur bios or tell us what to change?
Thanx in advanced :p:

I believe that I have the A2 core if I remember right, but I could be wrong. The only thing I did to the bios was extract it using nvflash and used nibitor to enable the 6600gt temp trick and changed my default clocks up to where they tested stable previously. Other than that, I used Riva tuner to disable the internal clock test and overclock. If anyone is interested in a copy of my bios, drop me an email or PM, but it is pretty simple to do yourself.

[computer_geek]

i am using 71.24 drivers here

[KingYubbo]

Flashed to the Asus N6600 from my Xpertvision 6600. Seems i can clock it alot higher from my previous 430/660 to 470/685!

YAY

http://i7.photobucket.com/albums/y267/kingyubbo/NGO77.jpg

[BOBO]

What should i flash my ASUS 6600 to break 420Mhz ? :(
WOW lucky, does ur 6600 have the A4 core? :confused:

[KingYubbo]

Nope.. it's got the A2 core (according to rivatuner)

According to an article i read (which i followed to flash to an Asus BIOS) the Sparkle BIOS overclockers further than the Asus BIOS.... so i would try to get a hold of that one.

http://www.digital-daily.com/video/peredelki/index.htm

That's the article.

~Edit

Also... one more question, has anyone tried BIOS flashing their 6600 to the GT versions of the same brand? eg. Asus N6600, flash to the 6600GT? I might try that with my Xpertvision 6600...

[BOBO]

Can i flash my A4 card with a A2 bios? or are the GPU's phisically different or somin and therefor not compatible?

[KingYubbo]

... i don't think so. Your card probably has a different layout... but correct me if i'm wrong.

Anyway, I flashed my card from the Asus BIOS to the Sparkle BIOS. From my Previous max clocks of 470/685, i have reached 511/680 with the Sparkle BIOS.

So i have reached 6600GT core speeds, it's just the memory that needs to be uped. In this test i have used the 80.40 forceware drivers, instead of the NGO 77.72's. NGO's probably give better performance, but I won't be installing them just yet.

http://i7.photobucket.com/albums/y267/kingyubbo/80.jpg

The best clocks thus far, without video card driver tweaking or windows tweaking. No v.mods, and on stock cooler with stock volts. Everything of mine is generic!!! I like my results :p:

[BOBO]

Should i flash mine to Sparkle?

[KingYubbo]

I dunno.... maybe... firstly, what core is the Asus N6600 you got? but i just reached a new high with my card. Same as above... just changed the clocks in Coolbits. 80.40 Forcewares:

Core: 520 Mem: 679

http://i7.photobucket.com/albums/y267/kingyubbo/520679sparkle.jpg

WICKED! FINALLY BROKE 67xx! WOOOOO!!!! More Than GT Core, half decent mem... and all with stock.

What are you using to get yours that high? programs? Bios's? .. .yours is already faster because of your CPU and motherboard and RAM.

nothing special ust got a lucky card with 2.8ns that is specced for 720mhz and a decent core, yeah my a64 is little faster than your cpu, can you post a link to a score to compare with?

Hi all. I have an Inno3D 6200 AGP. Softmoded it to 6600nonGT with temp sensor enabled. But the problem is, I can't o/c the core pass 430MHz. Ram is at 620Mhz. I had tried voltmoded it and the result is worse. Won't even run stable at 400Mhz. This card doesn't have a molex connector, maybe that's the problem. But I've seen people with the same card having the core clocked 470 to 500MHz without voltmod. Any help is much appreciated!

[Mahoney]

Do you have an ASUS 6600TD/128MB too? and if you do , is it an A4 ?
yep. ASUS N6600 TD 128 mb agp.

a4 core

[BOBO]

How high can you O/C the core and ram? :)

[KingYubbo]

My card also doesn't have a power connector... that isn't the problem.

I've reached a new record with my 6600

Clocks are now 531/697!

http://i7.photobucket.com/albums/y267/kingyubbo/vtests/sparkle2.jpg

Reached 6800!

[Mahoney]

How high can you O/C the core and ram? :)
i can do like 510 mhz with the core and 795 or mayve 800 with the ram...

but at that frecuencies the core cant perform very well. it doens crash. can run 3dmark and else.. but performs pretty bad,

so 440 mhz is the cool spot.. for core.. and 770 mhz in the ram with no artifacts

Damn, that's way higher than mine! I have already flashed it to 6600 bios and it still doesn't help. It just hang there in nature game test.

Changed my clocks around a little to see how much memory has an impact on performance

Core: 540mhz
Mem: 679mhz

Beat my previous score by 2!

To submit my results, do i have to have the Pro version?

No....you don´t need to be a pro user, or to have the pro version...

[BOBO]

If all core revisions are the same (A1,A2,A3,A4) then why cant A4 6200 softmod to 8 pipelines? Do you guys think if i flashed my A4 6600 with A2 Sparkle bios i could endupwith a unreversible 6600 with 4 pipelines? :(
I think i have a good point here ;)

[BOBO]

up :confused:

[KingYubbo]

I don't think so... you couldn't get Less pipes..... and plus they're both 6600 BIOS', so 8 pipelines would be enabled in both situations.

Anybody knows how to make a memory vmod on this card? My mems overclock only to 680 Mhz and changing of timmings doesn't help. I need to make a Vmod for memory but i don't know how

[msmolt]

Hi All. New to the forum and would like to know if any of you can give me a update on the 6600. Like Were can i find a 6600 gt bios to flash with? And whats the best drivers to use?

[[LCN]Knowledge]

Hi there, i had an Asus EN6600, those cards seems to clock good, mine was running at 430Core/660Mem. (stock cooling with artic silver 5)..

[zakelwe]

You should be able to get up to 650-700Mhz on core with volt mod and good cooling but then you will find that memory bandwidth limitations are really bad.

Sadly a lot of pseudo 6600GT's got into this class with GDDR3 and even Sli connectors so that was really a shame :(
