Unleash the Gladiator (RV670): 862MHz GPU Clock Limit Fixed

[HousERaT]

mascaras: auto-tune does not work correctly, at least it didn't for me. It put my core about 50Mhz beyond my tested stability which instantly caused my system to lock up and reboot.

[Blacklash]

Btw, do overclocking in Crossfire with Vista 64bit work well now?

As long as you disable driver check via f8 during post you can overclock a single card with Rivatuner. If you are using Overdrive from the CCC you need not do that and you are limited to manually setting 730 on the core with the HD 3850. You can get both cards to OC though. The bench I posted earlier was 730|1000 for both cards done from the CCC.

I can't get my second card to OC correctly with Rivatuner. I set the clocks then when I apply it drops back to stock.

I am hoping W1zzard @ techPowerUp! releases a version of ATi Tool that allows me to get my second card well. I'd love to have access to boost the voltage too.

[Blacklash]

Thanks guys, that cleared things up.

@Blacklash, was that run in standard mode or disabled for AI. Disabling the AI should give you the highest score.

Really? First one was advanced cat AI and second was standard. I thought disabling AI turned off Crossfire? I'll be happy to try it though.

[PhilDoc]

disabling ai disables crossfire. score drops from 27,000 to 21,000 though everything like Gpu-z and ccc say it is enabled.

Wow, that's supprising. With a single card, it seems to raise the score. Thats good info, thanks.

I thought people were saying you could get crossfire to run with either AI set to standard or disabled. Running a singe card I get a higher score with AI disabled. Looks like that may not be the case for crossfire, but thanks for giving it a try, I'll be getting my second card soon, so was curious.

To Crossfire work properly = catalyst AI standard

if you disable catalyst A.I = i think only 1 card score

With a single card, it seems to raise the score. Thats good info, thanks.

yep , single card with catalyst A.I disable always give + score

why dont you OC with CCC your second card????

with a OC bios you can go to 1500mhz core and 1400Mhz memory



CCC using Bios 830Mhz/1200Mhz

Ah ok,

So flash the 3850s with the OC BIOS and just use Overdrive. I'll have to try it.

Got a new toy a 2 days ago...



No mods no nothing... right out of the box

[heanwi]

Stock cooling too? Whats the temp @ load? Anyway, nice clock.

Its the GeCube HD3870 Turbo III so the using non reference HSF... :o

[Hazzan]

Arrived in my home last weeks but I try Yesterday....HIS HD3870 out of box no mood original bios in this card and litle tweak on my card....have some fun

[Monkeywoman]

WOW KWSW!! what make is that and where did u buy it from!!! i want one!!

[Calais50]

Its the GeCube HD3870 Turbo III so the using non reference HSF... :o

Those are nice clocks KWSW! I've got my reference Gecube 3870 running at 957Mhz Core (actual) and 1233MHz RAM (actual) with the standard unfixed BIOS. Is there any chance you could extract the BIOS from your Turbo III OC'ed version and make it available to us? I would like to try it on my reference Gecube card Have you tried loading the OC'ed cards BIOS onto your reference Gecube 3870?

My 1st post here, hello world :>

I got an X-Turbo III too, this is its bios: http://www.fileshack.us/get_file.php...70XT10.073.bin

It seems I can't get over 891MHz stable with my card (on Vista 64, Maximus Formula 0907, C2D E6750@3.6GHz@1.5v, Black Dragon 2x2 @ 900 @ 5-5-5-18 @ 2.0v). I then tried removing its cool HSF to replace the thermal slime with AS5. No luck with this, still stuck at 891.

The bios version is 010.073 and CCC lets me go to 885/1200 maximum (I tried the oc beyond this limit using rivatuner).

Any suggestion? :>

[andL64]

sry for OT but i got the the same problem with Asus HD2400pro 256mb, maybe some1 can mod the bios to get over 860 core?

thx

Thanks for the file Ratatosk Now I just need to work up the courage to flash it with the newer BIOS as I've never done that to a video card before It's weird that CCC only lets you go to 885/1200 because mine shows 885/1387 even though the BIOS is limited to 862Mhz core. Maybe the BIOS determines what speeds are available in the CCC??

As for you being unable to go over 891Mhz core speed, try manually raising the fan speed in Rivatuner to keep the temps down. If that doesn't help then the GPU needs more voltage so the only option is a voltmod.

Hi,

which Bios did you flashed on you 3850 to get 900Core Clock-Range in CCC?

Thanks

The "760" BIOS from here-

http://www.iax-tech.com/video/3800biosmod/03.htm

Cards in my sig will do just over 17k in 06 support by a Q6600 @ 3.53GHz on Vista x64. XP would be plus 500-750pnts.

[xMrBunglex]

do any of these BIOSes have a more aggressive fanspeed profile? i'm using stock cooling on my 3870's and want a new BIOS that forces 60% fanspeed, either when i start 3D clocks or at a certain temperature threshold. RivaTuner isn't so hot with CrossFire - i have to manually force fanspeed up and down before and after running 3D apps. i'd like fanspeed to be more aggressive when in 3D mode without having to run a third party app.

[PcCI2iminal]

I just replaced my 8800GTS with a HD3870 and wanted to c how good it overclocks.
I installed rivatuner 2.06 but when I click on customize to overclock I don't have anything except for low level refresh settings, desktop schemes and diagnostic , I have the lastest CAT 7.12 installed.
Is anyone having similar problems? (I tried reinstalling both the driver and RT)
i need a more accurate OC tool hehe
thanks a million in advance

well ,here is my new baby in action (with no vmods or pencil) and only CCC...
room temp is 18c

Sapphire HD3870 + Thermalright HR-03 GT


HD3870(850/1200MHz) + ATI reference HSF at low speed


HD3870(918/1250MHz) + Thermalright HR-03 GT + Scythe Kamakaze KKF92-01 73.6CFM(3800rpm)


at 931/1300MHz

[xMrBunglex]

great temp with the HR-03. that's awesome. i still can't get RivaTuner to work with both my cards with an automatic fan profile. if there aren't any pre-made BIOSes with better fanspeed control, is there a BIOS editor out there so a nub like myself can try to mess with it? i'll probably sell my cards when the next gen comes out, so i really don't feel like spending $100 on aftermarket cooling for them. i just want a BIOS that forces 60% fanspeed when the GPU starts to warm up.

no flash either? damn nice core.

I would also need this Bios. Any hints?
