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

[pazza316]

Guys I cant get ATIFlash the latest version to work on this card. What exactly do you type to get it to flash?

[Lightman]

Thanks for the results. From the few other results I've seen so far, it seems like everyone else is also hitting 877.

So the question comes to be askin', is it still a weird divider or are these things that starving for volts that badly? I ask because with the exact same clocks from the users I've seen so far, we're obviously seeing another wall caused by neither temp nor architecture.

If it's not the divider (again), then I hope to see some v-mod results after our resident bios and software voltage changing experts figure it out.

This will mess up your theory:



On TOP card it was 5-10s before lockup....

Actually reading the thread could help, there's a link to the flashing tool somewhere.

[pazza316]

Yeah I have the link and the new bios but cant get it to flash.

I am booting to dos but dont seem to be getting the cammand correct.

Could someone type this command out so I know what to do.

Thanks

Heres another that will mess up your theory....



Lightman we need more volts!!!!
My temps are slightly up, but still under control IMO

As i said, actually reading the thread might help. Directions were given there: http://www.xtremesystems.org/forums/...&postcount=121

Just thought i'd put a post out incase someone hadn't noticed. The New 7.11 drivers are out today

Yeap! Now we need Volts!

But I'm already happy! 877GPU 2600MEM in CF looks fantastic!!
And all that on stock AIR coolers !

[xMrBunglex]

Anyone know if a 600W PSU will power two hd3870's in xfire? its coupled with an x2 6000+, 1 360GB hdd, 2 DVD drives????

And how does the S1 sit with the stock ramsinks?

my 600W Zalman PSU is working fine. overclocked Intel E6320, two overclocked HD3870's, three hard drives, two DVD drives, five case fans... all's well.

[STEvil]

more volts and an LN2 pot.

877/2600 in CF is amazing... any 3dMark06 results from that?

[tbone8ty]

who will be first to reach 1000mhz core overclock? haha

[Goofisch]

Can somebody post some 3870 crossfire 3dmark scores? I,m still looking for some overclock results but cant find it on the web.
Thnx allready!

03 -54K+, 05 -25K+, 06 -16K+ with a E6850 @ 4Ghz, cards at 860/1301, hotfix drivers.

Is your HD3870 under water Miwo, aftermarket air or still stock?
If it is stock those are great temps!

*SS of 900mhz+ running*

Was that stable? If so, congrats.

Ok, so the divider seems fixed if there is some variation on top stable speeds, and where we see the hard reset happening (for most it seemed to be 890, same as Lightman). Theory debunked with that 900mhz shot.

Guess it's time to wait for some voltage do-dads, and when such occurrence happens, I imagine it will be mildly entertaining, especially since the 3800 products finally have a sink over the digi VRM (unlike the x1950pro). It's like it's waiting to happen.

Thanks again for the results fellas.

Edit: Out of curiousity, has anyone checked the VRM this time around? Is it of better quality than that found on the RV570?

Stable in the fur benchmark, but then I start dropping frames like crazy in 3DMark. Definitely needs more voltage......temps are fine. Highest stable/artifact free i have tested so far is 877/1314, which is pretty much the same as Lightman. Setting 885 MHz in Overdrive is actually 877MHz FYI, even though it "reads" 885MHz in OD. Oddly enough, the auto tune bumped my memory to 1379MHz, but I am definitely getting memory artifacts at that speed. Dumb auto utils, lol

Not too shabby with stock volts I'd say. To match a fully vmodded 8800gt, you'd probably need 1GHz+~ , which may very well be obtainable once someone comes up with a way to adjust voltage via hardmod / tweaking app / modded bios.

No crossfire results from me, sorry :p

That's what I figured, thanks for the update.

Not shabby at all, especially since it seems relatively easy to obtain by most everyone...They are definitely holding back potential (through voltage) because of the cooler it seems. I'm sure someone will find a way soon to fix the situation, but I personally think you're going to need to see way more than 1ghz (1100-1200?) to match those tricked out GT's (perhaps not stock vs. stock, but certainly with both using aftermarket cooling)...If that's possible remains to be seen imho, but still, whatever the case ends up being, it's always great to see more value squeezed out of the cheaper (and easily obtainable) option, as it's certainly why I myself mod/overclock (to save a buck here or there). The closer it gets to it's competition by any (reasonable) means necessary, the sweeter it becomes.

Not the highest overclock on the CPU, but 850/2500 on the GPU. Running Vista with ATI hot fix drivers (stock).

[GAR]

Weak.........IMO

[Lightman]

No problem! But my score will be skewed because of CPU. Still I can run full suit and then you can compare detailed results .

Canyon flight is scaling very well on my machine, but other tests are CPU bound to a level that GPUs are utilized only 50-70%...

Results after my work

[mattmartineau88]

i'm just trying to decide what kit i need for upgrade to crossfire 3870's, do you reckon i should go for:

MSI K9A Platinum Crossfire (Socket AM2) PCI-Express DDR2 Motherboard
http://www.overclockers.co.uk/showpr...d=5&subcat=808

or...

Asus M2R32-MVP Crossfire (Socket AM2) PCI-Express DDR2 Motherboard
http://www.overclockers.co.uk/showpr...d=5&subcat=808

or....

MSI K9A2 CF AMD 790X (Socket AM2) PCI-Express DDR2 Motherboard
http://www.overclockers.co.uk/showpr...d=5&subcat=808

- AMD® Phenom/Athlon/Sempron CPU.
- HyperTransport 3.0 supporting speed up to 2600MHz
- AM2 CPU supports HyperTransport 1.0
- AM2+ CPU supports HyperTransport 3.0
- AMD® 790X and SB600 Chipset
- Supports Dual DDR II 533/667/800
- 1x PCI Express x16 slot with x16 operation
- 1x PCI Express x16 slot with x8 operation

also does anyone know about the operation speeds ie. would the first two motherboards run at 16x16 or 8x8, i've read everywhere but cant seem to figure it out :S

Thanks in advance

[Mackai]

i would take a look at Gigabyte GA-MA790FX-DQ6 AMD 790FX (Socket AM2) PCI-Express DDR2 Motherboard http://www.overclockers.co.uk/showpr...d=5&subcat=808 yeah it might be a bit on the pricy side but , 2x16 and 2x8 for cfx , the asus M2R32-MVP has 2x16 and the msi also has 2x16 , as far as the info i am seeing about those cards. ( hope that helped )

this scanning is inadequate
the ati tools artifact scanning is better

using the ozone3d i says 885 is artifact free for mine
ATi Tool says 865

using 3dmark06 and crysis have to say 865 is artifact free
