hmmmmm.......
so you run 3d06 with 1100mhz on stock everything? mind showing me a link? strange how nobody i have seen can even get close to that. 955 mhz takes me 1.4v.


@hipro1300mhz+ is redicccccccccccccccccccccc. congrats.. :up: :D :cool:

:eek: I.don't.believe.it. :shocked:

LOL, easy there guys I though we were talking about the crappy DDR3 on these cards.

My max gpu clocks on air are 900mhz with 1.25vgpu. No ones pushing 1k+ gpu clocks on air, at least I haven't seen.

you had us going there for a sec hahahahah

Hahahah, that was funny somehow.
Max i did was 1060mhz on the rams.

How much are these mods needed when you bench the card phase cooled?
If it's mostly useful to defeat the coldbug after -130c, then i won't need it.

for sure he had us going. :rofl: i was like no way is he hitting 1100mhz CORE :p:

and it worked out graet , cascade on naked gpu's -100°C evap and -81°C core .
had to stop becaus after 3minits i got water all over the place :D
here is a bad pic of the mod :)

thx george u are the best, pleas checkur pm's ;)

I'll start soldering solid caps from old Msi mobos :D
I have MSI P35 Diamond which is broken and there is some solid caps :D

I also did the "Hipro capacitor" mod for my 2900PRO.
I just did the full transformation (before it was 100% stock) so the overclock fun just has to come (but I won't go to crazy this time because its my main card). Before (@stock fan100%) it did 850MHz core now it does 890MHz with stock bios 1.15v. I still have to test with my edited biosses but with stock cooling i did ran some benchmarks with 900MHz 1,25v (quick runs, card runs hot as hell).
My target is 1GHz core. Ok enough talking here are my pics:
I used 8 330uF 16v low ESR's, works like a charm...

I realy like my temps @ watercooling, 31 degrees is miles better than the crazy loud stock aircooling

Thanks Hipro :up:

So you got an OC increase?

Try to shorten the legs of the caps, i think they will higher the ESR dramatically.

Do you have a datasheet of the caps? What ESR they're rated at?

Thanks for infos :).

No, the watercooling and the better VRM cooling did raise the maximum overclock. The capacitor mod didn't (alltough not with stock 1,15v, only thing I tested).
I don't ESR rating of those capacitors, I just let them ordered at a local specialized electronic shop. The man form the shop ordered them form a wholesaler in the UK it took quite some time searching for 8 capacitors with the right value that were in stock in the wholesaler.

Can someone confirm that long legs of a capacitor causing a significant higher ESR?


My overclock results:
1,20v > 910MHz
1,25v > 940MHz
1,30v > 970MHz
1,35v > 985MHz

What's a safe 24/7 voltage for my card?
I have to do more testing but I was thinking of a 1,3v bios @ 950MHz.

Those are suicide speeds, 3dmark stable or full stable? :D

Full stable, 100% artifacts free and tested with rthdribl @ 1360x768 16AA.;)

"lets get serious now"! είσαι μεγάλη μούρη! u rock

I always like it when the core freq is higher than mem freq:D Great stuff, hipro!

What does this card do on normal air cooling, btw?:)

I used to only bench CPUs before, but after testing my own 2900pro and reading this thread I really need to start fooling around with some GPUs as well:D

btw, my card (2900pro) does 865/1200 3dmark03 stable / stock air / 1.15v -2.2v (stock). 1200 mem is sweet, but not sure about the gpu. No point in looking for another 2900pro (for xfire) if this one hasn't got any REAL potential.;)

Sorry guys for the late reply BUT I'm TOO f(l)ucken busy lately..... :(
SO this post of mine will be quick coz I'm in a hurry but I'll re-post you within this week.....

TIP: CrossFire at 1300/999 first VGA and 1300/999 second VGA, 2k6 Canyon Flight ~140fps....
CrossFire at 1300/1030 first VGA and 1350/1030 second VGA, 2k6 Canyon Flight ~ ???fps :D :p: ....

I'd place my bet on "more fps" :D :D

142? ^^

My bet is 150 :D.

I forgot to add that the above fps was done with the ASUS Blitz Extreme and 2 x 8 PCI-E.....ADD now another ~2 - 3 fps more on P5E3 WS Pro 2 x 16 PCI-E and calculate..... :p:

hipro when are u willing to replay pm's ?

Hipro where are you ? No benches at all ... ? :(
Come on man, we 'd like to see some WILD action going on, from Hipro the Greek Legend ;) :)

Sorry guys but too much work to do.... :(
BUT I'm ready for CrossFire now.....Everything are settled..... ;)

@ blind_ripper: as soon as I reply to all 270 PMs, you'll be in them too.... :D

Then I'm happy Hipro ;) Come on, give 'em a reason to cry about ... ;) :D

2x 2900xt CF 847/960 3dmark2006 SCORE: 22036
