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

[slugzkea]

did you test the oc on your vid card, i was able to go up to 891/2700 and have no artifacting source but it was slower than 891/2300 which was stable

test it with ati tool

I tested using 3dmark06, playing cod4, nfs carbon, cs s, tf2 etc.

from my experience, ATI tool is the worst thing to test anything.

Playing nfs carbon at highest settings is the best way to test stability and artifacting because:


- The game forces your GPU at 99% even at main menu, and at all times during the game.
- Because of that, your card is constantly stressed not just visually, but by inputs as well
- Artifacting is real time and is easily noticable during memory access.
- The game is super sensitive and crashes even on default system clocks and nothing running in the background so if you can achieve 4 races without crashing, you're stable! lol

[afireinside]

yep you can pass 864MHz in crossfire with bios moded because bios mod it has
core/mem 875/1250MHz after you flashed your card will boot to 875/1250MHz instant

How does this 864mhz wall work? Is it insta lock or is it just not stable after a while? I can run 864 for 3d03 but my scores actually seem to be lower and it crashes quickly in games.

Also, have you found a way to put both fans @ 100% without disabling CF and doing it with rivatuner, then re-enabling CF?

[ZoLKoRn]

What OS on you used XP or Vista ? if vista i don't way too it have only disable
CF and enable again, if on XP you can select 2nd card in rivatuner and set 100%
without disable CF

The Revival (HD3850) kicks quite hard too

Today I desided to play around little bit with one of these HIS HD3850 cards I had on my desk.

I bolted my old trusty Thermalright SI-128 heatsink on the GPU and did the VGPU mod.

HD3850 cards are easier to mod because there is no separate cirquit for VDDCI and the voltage is synchronized with VGPU, just like it should be.

The highest frequency I could reach was 972MHz for the GPU and ~1000MHz for the memory.
VGPU/VDDCI voltage was 1.54V during the tests.
DRAM voltage was untampered like the frequency shows.

With these clocks 3DMark06 scored 14224 points.

HD3850 certainly isn´t the fastest card around but it damn sure has superior "Boom" () per buck ratio

HIS HD3850 is being sold for 149€ (incl 22% tax) here in Finland.

Yes, I did some ROM burning before the tests
Soon...

That is simply sick!

Good work The Stilt!

That shows how good AMD/ATI yields must be!

Damn Yeah running vista here. Need the DX10!

Stilt> How do you control this VDDCI voltage on 3870s? And what is "ROM burning"?

I'm such a noob now

WOW!! Almost 1Ghz with 3850 Over 300mhz above the stock. Must be a much more happier performer And with AIR?

[Dr.Spankenstein]

While I agree that a 300MHz OC on the core is AWESOME, we have to concede that fact of a Kentsfield CPU, 1600MHz ram and (judging from his wallpaper) an X38 chipset (PCI-e 2.0) helped the score a great deal.

Not downplaying the accomplishment, just adding perspective...

To be honest, my next two upgrades will be a DX38BT and some Mushkin HP3-10666. Then I'll have something to plug my 2 3870s into!

Cheers!

Just assumed it would be better to get a gfx with full bandwidth on the PCI-E??

2x PCI Express 2.0 @ x8 is 2x PCI Express 1.0 @ x16

remember PCI Express 2.0 = 2x speed of 1.0

anyone else got a hot temp problem?, and vpu recovery kicking in and kills the fan to zero %

Realy nice. They hit the same clocks as the HD3870 You have quite a nice card there for 149 euro

[2DIFF]

Greetings! I have a HD 3870 from Gigabyte (mod. GV-RX387512H-B). I was wondering if anyone here could answer the following questions:

- On the screenshots posted here, I can see Texture/Pixel fillrates of 14+ GPixel/s. GPU-Z only shows 4.8 GPixel/s in my case. Is this because: it's only one card or because I'm running it on a PCI-E 1.0 Board? Bandwith difference is very minimal (people here have ~80, I got 72 GB/s), so I don't really understand...
- I was running a Crossfire system before (2x HIS X1950 Pro 512Mb) and I now would like to get a 2nd HD 38xx. Would you recommend to take a 3850 for the 2nd card? Or would this slow down the 3870 wich is higher clocked?
Thanks already!
When it comes to performance: I expected much less from this card, so I'm quite happy. I always used winclk to oc my x1950's, but this tool doesn't work with the 3870. So I used Overdrive, but the highest stable settings were 830/1306, wich gave me 11737 3DM06 points with the system below.
Thanks for any suggestions.

ummmmmm how did you break the 850 wall on the 3850 ive been waiting for the bios for EVERRRRRRRRR.... im stuck at 850 with no matter the volts please help

But it seems that it´s impossible to up the vcore above 1.33v with the modded bioses, right?

[golfjam]

Man, I got 2 last friday. Spent the weekend playing around with crossfire and all I can say is I'm dissapointed. Single card works great, just like my previous 8800GT but in CF no game works!?!?! I've tried COD4, Company of Heroes, UT3, Crysis, Supreme Commander and WIC. I've tried 7.11 and Crysis hotfix drivers. It crashes 99% of the times. At least I got 18456 in 3DMark06 with no OC. All I can say is it sucks big time!!!

My bet is on your power supply not being able to handle all that at load.

More like he overloaded a rail.

[golfjam]

By the specs, 750 is more than enough. And all the rails are well distributed. It doesn't actually crash but is unable to load games. Funny thing I've emailed M$ for a solution. They emailed me back with a new hotfix for Vista 64. I could load Crysis before but now it's impossible!!!

[STEvil]

Oh, Vista... well that just says it all

[golfjam]

Same with XP. I'll get a 1200W tomorrow. If it doesn't work I'll just return it. Will post results later. Thanks!!

[gaidin]

I think I need some Vr's and a 900/950/1000 bios

Does the guy from iax-tech post here does anyone know? If he could upload a few extra BIOS speeds that would be awesome 900/1300 FTW
