RV670 862Mhz CLOCKLIMIT FIXED !

[Pinchy]

So it is more or less about the same, not bad when it is about 1/2 the price. So a new motherboard with the 2.0 specs should make the card faster, right?

I dont think a PCIe 2.0 mobo will make the card any faster mainly because it doesnt use the full bandwith of PCIe 1.0 ..

OK, I was not sure what the PCIe 2.0 performance was... Still can't argue that this card is way more bang for the buck (vs 2900). Unfortunately it looks like its prices, and the 8800gt are going to keep going up.

TRT, how does the vreg cooler look? I may order a cooler and want to know if it looks like copper ram sinks will fit on the vreg?

Haha, very nice and interesting. Cool to see TPU getting some play from theINQ.

Yeah it is, and it really pisses me off when people say that it's not a creditable source of information - bullcrap! It's a damn good site and if you don't understand their somewhat satrical take on some issues then go to another site. I'd like to see some proof that this site isn't a creditable source for technology news. I bet it's the old Frudzilla malarkey that's putting people off.... rant over!

about 200 points is my best estimate behind a 512mb

is that 200 point behind in a 3dmark.. ???

have a look at my 3870 score in the lightsmark bench.. i aint sure exactly what the thing measures but whatever it is the new 3870 seems to do it nearly twice as quick as the 2900 series ati cards did..

is the winbench flash thing safe to use by the way.. ??

If overdrive is maxing you have you tried the latest Rivatuner release Trt?....it is said that Rivatuner will overclock the HD3000 series, your performance limit at overdrive max may well be overdrive induced in which case you should be able to push forward with rivatuner.

Also if I understand rightly you are not on Cat 7.11??

Does this fixed BIOS void warranty? Is it supported by AMD/ATI?


My HD3870 should arrive in a few days. I wish to clock the shit out of it.

i am pretty certain it will void warranty.. which is why i am still working up the courage to flash mine.

i am on the new 7.11 driver tatty.. just the driver i left the rest alone..

I've already flashed that "fixed bios" onto my Gigabyte HD 3870 2 days ago. Yes, it did break the 862MHz lock. However, in my case, the ATI Overdrive will always push the core and memory frequency all the way upto the limit of the sliding bar and of course, it fails the 3DMark06's stability test. Thus, for me, the "real" function of ATI Overdrive becomes meaningless...weird!

It seems that a real workable bios editor for HD 3870 is absolutely needed for editing its frequency、voltage and fan profile...etc., at least the fan profile...I've found the stock fan is quite powerful since I set it at 60% by using the RiverTuner and just got 35-36C at idling and 59-60C at full loading, with acceptable noise level.

Really hope some experts can make a workable bios editor for this nice vga card! Besides, I've heard of a 1.377Vcore bios for this card, any experience?

Would it be worthwhile not to install the CCC and just manage the card with RivaTuner?

To be honest, I prefer the CCC to any other ATI tools. I'll try it and report later, thanks for your advice anyhow!

I only ask because I have a 3870 unopened and may try it myself when I install this weekend.

Let's share the experiences! I've got to go since it's 4:38 a.m. in the morning.

 

[trog100]

does anybody know how to set rivatuner to run the auto fan speed side of things.. i couldnt figure it out.. the ccc is doing a lousy job i dont think it even turns the fan speed up at all for 3d mode.. i recon it runs about 30% all the time..

someone to the rescue please i aint geeky enough to understand rivatuner.. he he he

Yes............open up the app, click on the 2nd drop down box where it says "customize" (mine says "320 bit G80 (A2 revision with 92sp and 640MB GDDR3), yours of course will say 256Bit RV670 etc etc.

Then you get the line of Icons, click on the first (the pic of a graphics card)

Then you will see the fan controls, choose auto or fixed dependant on what you want, the rest is self explanitory from there, make sure you check the "apply on Windows startup" tab.

i got that far tatty but i gathered all it did was run at the ccc settings.. either way it dosnt seem to work.. it certainly aint following the fan profile it comes up with and things run the same ticked or unticked..

the fixed fan speed works thow.. its how to alter things in that power user bit i was interested in.. its all in that other thread of mine..

what i would like is to run the CCC but have something else controlling auto fan speeds.. 0% to 40% runs things way to hot.. 0 to 60 with 60 coming in at at 65 C would work fine..

Right, power user is pretty simple but way to complicated to explain in the forum, I have used it a few times, let me have a play with the Power user fan settings then I will PM you, probably be a bit later today as the wife wants me to test drive a car she wants but I'll be back!

 

[trog100]

update.. so far even thow the new bios seems to help things along at first.. the card passes the overdrive self test thing right up to the overdrive max of 885.. it hasnt panned out this way..

i dont know if crysis is fair a test for stable clocking limits but i have had to slow my core down to 840-sh to play the game for lengthy periods without vpu recover being triggered..

this is with a fixed (rivatuner) fan speed of 55% keeping the card temp at about 70 C.. by default the card runs about 90 C..

it will run the 3dmarks at around 855 but if it wont game it dosnt count for me..

so i get 840 at 70 C as a max stable core speed for everyday use..

other cards might differ..

Trog, sorry it's taken me a day to get back to you on the power user in Rivatuner, been trying to install my new hardware....slow process!

You cant do power user the normal way cause that requires the cards driver string and the HD3000 is not supported yet but there is another way that might work:

1. Go to the power user tab.
2. goto Rivatuner\nvidia\fan\currentdevice
3. Expand that branch
4. Set "apply at startup" to "1"
5. Fan speed 0 is 2D so set at "1"
6. Fan speed 1 is low power 3D so set to "1"
7. Fan speed 2 is performance 3D so set to "1"
8. Save presets by clicking on the floppy icon below.
9. You should then be able to set fan control on bottom drop down on main page under "driver settings" clicking on the Gfx card icon and then set fan speeds in there for the 2D, low power 3D and perf 3D settings..

I have tested this method and it worked for me but that might be because I still have the 8800GTS in and not an AMD card (I still aint got round to installing the 3870 yet)

O.K., I tried this and I think it worked. Before I tried 840/1276 and it would crash (also I wasn't messing with the fan speed and I haven't replaced the stock TIM with AS5) but after doing this trick I tried 850/1300 on Crysis Demo (for a long while) and a few 3DMark06 runs without a hitch -- fan set @ 70.

You mean you tried my method in Rivatuner?

 

[btarunr]

What's the stock-TDP of a RV670?

 

[TonyStark]

125 W .... I think.

 

[btarunr]

125 W .... I think.

In your opinion, is it too high for a 55nm fab GPU?

 

[trog100]

this could be drivers and it could be crysis.. but i am down to 832/1226 for stability in crysis.. the card temp dosnt seem to make any difference..
