Sapphire HD3870 CF@904MHz Stock + QX9770 water

[ZoLKoRn]

i try to play HD3870 with QX9770 by i flashed bios mod is i see here and i can OC to 904MHz of core on stock cooler, ambiance around ~ 24 ํC
and cpu can OC to 4500-4620MHz on water but after benched i think performance look like to low i don't know why ?

btw. i need post it results for sharing and need to know, how you thought with this results from it ? it ok or really low , Thanks to all for your comment

spec..

QX9770ES@4.62GHz,1.552V (4.5GHz,1.560V only 3k06)
D-Tek + 3fan Alphacool rad. + DB-1 + SS FM121 fan
ASUS Maximus Extreme, bios0403
Cell Shock 14400C8@840MHz 7-6-5-15-1T (set in bios 1T but cpuz show 2T )
Sapphire HD3870@904/1124MHz, stock cooler (bios moded boot@875/1250MHz), catalyst 7.11
Seagate Barracuda 7200.9
Thermaltake 1.2kW




Results....











some my thought now, i thinking maybe QX9770 it have only high FSB but performance slowly than QX9650 on same cpu frequency
but maybe it will very stupid ideal from me and i'll try again on QX9650

Good overclock

[G H Z]

Pretty sick results for H2O, 4.6Ghz+ under 1.6V

Good work Zolkorn

It must be hot there :P

I knew you turned on the air-con. The GPU clock is great, but you may need to find a 'good combination' between GPU & Mem clock for maximize performance. Cat 7.12 would be getting better for the CrossfireX system.

Anyway, how much does it cost for HD 3850 in TH (in Baht) now, I just would like to compare it with the GPB price.

Nice overclocks.. wish I had a good clocking QX9650/QX9770.. mine tops out at 4104-4230mhz on air/water at 1.5-1.6+ vcore heh

zolkorn how loud is stock cooler?

[Gunslinger]

Stock cooler, when at 100% sounds like a helicopter hovering at desk. Did you make sure both cards were OC'd exactly the same? I made that mistake a couple of days ago using ATI Overdrive, an OC run ended up almost the same as stock numbers

HD3850 price ~ 185USD and HD3870 price ~ 250USD

OK i'll measure it for you next time

i think it sure for both clock on 2 card, i used rivatuner for overclock not used overdrive and try check clock by GPUZ 0.0.9 version it can show real clock

78K on CF is indeed a "little" lowI think a normal result for that would have been a 95K-100K right??

With 7ghz Yorkie maybe
CF and SLI affect only nature points, all other tests in 2001 are pure CPU/ Mem / Chipset power and Optimizations

[NiNe_iZe]

Nice result, Bro !!

[andre X_X]

very nice result bro....
love the CF....

[satein]

Thanks

Arghh... it just changes the unit again
Better save and buy it at home then

Is Catalyst AI set to standard?

[Iceflight]

Something's wrong with the score, I'm at 4.3ghz and the scores higher,

BTW I'm priming at 4ghz at 1.32v vcore.........L739A640

Yes, it standard setting.

aha looked it have something's wrong sure, but what wrong ???

nice score Iceflight, thank for sharing

btw. what clock speed core/mem on your card ?

[Iceflight]

Yes, it standard setting.

It's only 855/1261.......

KEEP GOING. It is time we got some new blood in the world record area.

[Morais]

Ive noticed you are using both bridges to crossfire...have you tried with only one bridge connected?

[PytonOrm]

i have get some new stuff to Ati Sapphire HD3870 and i can run at memory 2,9Ghz on air

Not stable on 3dmark but 2,8ghz i can run

[ZoLKoRn]

2.9G memory it amazed!, i can run max to 2.7GHz and stable only AM3 now

--------

Thanks Morais , i'll try it

[Sampsa]

Zolkorn, download GPU-Z and check you PCI Express speed. I have faced some strange problems with Gigabyte X38T-DQ6 and Radeon HD 3800 graphics cards.. sometimes PCIe bus is running @ x1 or x8.

edit: ah.. now I checked your screenshots.. everything seems to be ok

[ZoLKoRn]

zolkorn how loud is stock cooler?

I checked yesterday it around 70-72dBA on 100% fan both card and Ambient noise if shutdown this system are ~43dBA

[Solarfall]

hahaha ZoLKoRn dude why do you have your stuff at the floor, don't you have a table ??

[ZoLKoRn]

My table it full not have area to put again because now i run 3 system in same time hehehe...
