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

[GAR]

Could be that's all your memory has, but try Riva Tuner. I tried the latest ATI tool beta and din't have much luck with it.

Yup, i returned the card already, as i was very disapointed with the performance compared to the 8800GT, in one word, the 3870 got hammered in all of my tests, by 20-30%....except for the source engine games.....it was pretty much head to head

[Sage]

interesting i put my m8s 8800GT side by side with my 3870. Yes the 8800 was faster thought the ATi looked MUCH better.

I agree, the ATi looks a bit better but nothing to go crazy about, not noticible in most cases, alsoa good picture doesnt matter when the frames cannot keep up.

That's what I've been hearing, and it's been making it soooo hard for me to pick, I want the best image quality I can get, but I recently bought a 24" monitor and I have an am2 590 sli setup (bought it before conroe, didn't know about conroe since I didn't pay attention to tech news at the time) so I need a fast card if I ever want to play crysis with any aa.

The g92 gts interests me, but the 3870's picture is supposed to be superior, I'm not sure if that's due to nvidia cheating on their drivers or ati just having the superior gfx engine, but either way, the decision is hard to make, especially with two of the cards being sold out and one not released yet

[hstuehmeyer2000]

has anybody gotten the gecube hd3870 OC bios??

and GAR never tried single card yet..
but my crossfire setup for hd3870 kills the 8800gt sli rig that i got for my gf..

how about msi 3870oc edition http://www.mvktech.net/components/co...es/MSI3870.rom

[AliG]

if you look at expreview's comparison, crossfire does seem to scale far better than sli, but the problem is the 8800gt is so much more powerful than the 3870 such that if you can't afford a second card it's not worth it

[GAR]

can you consider 23mhz an overclock? lol
that bios uses the old bios, and it doesnt have higher voltage.

[PhilDoc]

Guess, I should consider myself lucky to get the 114 I got out of mine. With the price the new cards are selling at, I think we'll be see a lot more going with a two card system. Its certainly motivated me toward that direction and just what I've seen on this forum, there's quite a few headed that direction. Nice to see some decent performance at a decent price.

GAR, I’m sorry to hear that you are so disappointed with the 3870's performance compared to the 8800GT. However, did you happen to see this review of a 3870 crossfire compared to a 8800GT SLI?

http://en.expreview.com/?p=53

The crossfire scaled much better than the SLI. I wouldn’t have acted so hastily, as ATI Drivers only keep getting more performance as they mature.

[Sage]

yeah its a bit tricky to choose. though nvidia are well known for dropping quality on well known games and benchmarks to get better benchmark results..

I am happy with my 3870.. can play Crysis @ 1680x1050 Very High everything

I did see the review, but i cannot make a $500 investment over my 8800GT over one review you know, i would need more proof and more reviews of the same sort......my 8800GT is a good overclocker so i think crossfire wouldnt have that much of a improvement in my case, thats probably comparing a stock 8800GT in SLi

GAR = Nvidia employee?

GAR = Nvidia employee?

not even bro, i have had the pleasure to play around with both cards, and im stating my results....thats all.

he must be a Gigabyte employee as well then if you read any of the GB posts of his

Hi,

Ati Tool's new version is out there. AtiTool 0,27 Beta 3.

- Full Vista and XP64 support
- Support for all ATI RV6xx ASICs
- No changes to R600 support in this build
- Better support for multiple adapters
- Latest NVIDIA non-WHQL drivers with some G8x cards not supported
- Better handling of clock step sizes
- Fixed vertex/pixel/unified shader reporting
- Added detection for about 20 older and newer ATI ASICs

With 55nm GPU, decent cooling (may be even with the stock fan) and increased voltages HD3870 may fly past standart 8800gt.
(Don't forget to use the new bios solving 862 MHZ barrier problem.)

Give it a try.

Especially you Miwo, with having a good cooling solution.

Just downloaded it and uninstalled the previous version (ATITool 0.27 b2) and installed the beta 3 version...

It certainly does detect the clock and mem correctly but when I used it to overclock it failed to pass the furry cube test but with RivaTuner it works fine...
So not much of an improvement for the RV 670 cards...
But thanks for the good info...

Are you able to modify the voltage with this new AtiTool? If you can, then you may increase the voltage by AtiTool first, and then increase the GPU clock by Riva Tuner.

I hope it works.

I've checked the voltage box if it shows up a control menu for the voltage but didn't...
Don't have the experience using ATITools for voltage modification but for now it doesn't seem to work out for me...
Has anyone tried it out yet?
I'm really curious if the voltmodded BIOS really works because there are few people saying the BIOS is not working...
Anyways I hope people don't post garbage like 8800GT is better and ATI is trash and stuff like that...
Doesn't really help and considering the nature of the forum it is inappropriate..
For those who wants to stick with 8800GT I strongly suggest that you to go to another forum for your fuzz and don't clutter this forum with garbage info...

[Miwo]

ty for the heads up, but unfortunately voltages aren't working on the new ATITool version. It is a beta after all, and this version pretty much adds clocking support on RV6xx cards. Perhaps in the next few revisions, W1z will have figured out how to adjust the voltages in software (if possible), you never know

until then, our best chances of getting a vmod are in this thread
http://www.xtremesystems.org/forums/...d.php?t=166623 , since modifying the voltage table in the bios does nothing.

[slugzkea]

Here's a 3dmark06 basic test result. I've noticed very little artifacting with this memory clock and I truely believe it's because of that stupid goop between the copper heatsinks and the RAM. I'm going to purchase some copper ram sinks and aim for a high RAM clock.

I truely believe I Can hit the 12,000's with this card

[brakezone]

I got the 3870 and i think it is awsome. an 8800GT is an even more awsome of a card, it just is not always easy to find one at the price you want to pay.

As far as the comparison that GAR drew with his card: Firstly, you have to consider that the 3870 was significantly cheaper than the 8800GT for the majority of people. Secondly, the 8800GT appeared to be overclocked and overvolted where the 3870 was not voltmodded or even sporting an average overclock. I'll definitely give you the fact that the 8800GT is a better card, but the comparison seems a little unfair granted the 8800GT you have is a above average clocker and there aint even a voltmod for 3870 out yet.

Now, Aside from this, two other things.

1. be careful with memory artifacts as memory is way more fragile than the core
2. the core doesn't like being over 60C when overclocked

On mine it will do 860/1250 easy as long as the core stays below 60c. The memory on mine was fine at 1300 until the deep freeze test in 3dmark06 (in other words it won't do 1300). I'm not even messing around with it further until I get better cooling and some volt mods exist.

Okay, now food for thought

-On paper the 3870 looks like it would outdo the 8800GT, heck even the 2900XT has better overall processing capability and memory bandwidth. Why precisely does the 8800GT outperform? Is it because the 8800GT is better at texturing? We all know it has proven itself a great card, I've just not heard any precise answer as to why.

Many say it's because nvidia is in bed with the coders and yes nvidia seems to be better in texturing. I would also like too see ati's shader clocks to go up

What's up lately with those peeps making their first post after 4 years

Keep it coming guys, seems like the mods are about to surface in no time
