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

[jedimindtriks]

besides that how do yo know the clock is stable or not?
I used ATITool 0.27 B2 and turned on the 3D renderer (Cubic Fur) and scanned for artifacts
Is there a better way to see if your clock is stabilized aside fromt the above mentioned method?

i think atitools artifact scanner is the best, even when i get a few artifacts on it, it doesnt allways show in games

It is said on the manual to use a 500W or higher PSU though I speculated that the spec they are giving is way too high for standard purpose... just a way to avoid the blame when the graphic card gets burned with the PSU...

My CPU is E6300 @ 2.7GHz and the RAM is running at 482MHz...
couldn't get my RAM to run at different ratio so used FSB : DRAM spec = 3:4
CPU = 386*7 = 2.7GHz
Sucks...

I roughly calculated the total energy consumption used by my system and it should be around 270Watts even with the graphic card.

Do you think PSU is holding me from further overclocking the video?

What about the temperature?

Spuggi says that he/she is using the stock cooler and with the help of the BIOS overclocked it up to GPU@891Mhz and MEM@1332Mhz...

I could do that too but system either crashes or give out a VPU recovery session.

I have stabilized it the GPU@840
further going causes VPU recovery or crashes after exhaustive use...

If your power supply is of poor quality (no-name brand as you mentioned originally) then I could see this system causing it a few headaches...

I found that the 6 pin connector for the PCI-Express power supply line has a capacity of 18 ampere...

Two 12 volt connection with total of 300W for the two.

if you go to the link might not be able to read the text but can see the table...

How much does the graphic card actually consume?

Is the amperage not enough to overclock?

At a glimpse the spec seems sufficient...

[cstkl1]

hmm i tried that 1.377v bios

i have a prob
i can run 900/2500mhz on stock cooler fine for each card
but when i crossfire...it will only be artifact free at 864/2500

[slugzkea]

You should get 1.377 Vcore with this BIOS image.
(I don't have a 3870, so i cant verify)
Is someone brave enough to try out?
Use at your own risk.
(Oh and of course the checksum is no longer valid.)

I did, can't seem to get the core stable in the 900's...gonna try 877/2600

Seems you'v used the 1.377 Vcore BIOS mod...
Is there actually a difference with the originally posted BIOS?
Have you checked the vcore with a voltmeter?
How much load do you give the stock fan and how high does the core temperature rise?

UPDATE: 3dmark06 score was 11077, that's not very high if you ask me. 877/1236 were the clocks.

e6300@3.5ghz
ocz 6400 platinum xtc rev2 5-5-5-15 1:1 ratio


The main difference i've noticed is crashing instead of total lockup at high clocks like 890-905's.

I dont got a voltmeter.

I leave the fan at 68%

core temp floats around the 50's

tried 895 core, crashed. going to work on the mem now

18A @ 12v = 216w.

PSU looks similar to a few around here, they're fine without a huge overclock...

i have the thermaltake psu with one 12v @ 18A.

will this be enough to run one 3850? maybe a 3870?

???

[STEvil]

it'll work.

[bl1zZ]

Can someone mod an unlock bios for HD3850's?
Many others and me would be very thankfull!

UPDATE:

My final OC results are:
890 core
1281 mem.

I don't know how you guys got 1300's for mem, 3dmark06 would just crash.

How i did it:

- Uninstalled all drivers then used driver sweeper.
- installed 7.11 display driver WITHOUT catalyst
- Disabled hot key proller
- Used RivaTuner for 890 Core, 1281 mem
- Fan forced at 70% at all times.

I ran 3dmark06 3 times in a row, score is 12042.

Good enough for me! now it's time to do some serious gaming.

all cards are not created equal. Both of mine will run 1300 on the memory but they run 865 and 840 on the core.

I need more volts.

Probably true, I'd say that most cards that clock a little low on the core are voltage deprived. I can say that a little extra cooling does help. Putting a V2 on mine added 14 to the core.

Definitely agree with you there.


The stock dual slot cooler is definitely budget rate, esp with the way they have the fan speed tuned.

They should grow a pair and be more aggressive with the temps. 90C sucks

UPDATE:

I had to go back to the bios without the volt mod. Riva tuner screwed up my clocks, CCC would not read them at all kept displaying 000 and I tried uninstalling using drivercleaner PE several times...

Flashed back, using CCC 7.11 core is at 885 (in CCC) and going to install rivatuner for fan function ONLY.

if all is stable like that, i will try and up the RAM But the ram doesn't seem to OC very well...

Once you reach a clock that's over what CCC can reach (885) it will stop reading. From what I can see that's normal. That doesn't mean your clocks are screwed up.

As far as your memory. Every card is different, but you'll probably get some better memory clocks as well with better cooling. With the stock cooler I was hitting in the 80's load, with the V2 I'm getting in the low 40's load. That extra heat has to affect the memory clock as well. At least a little.

UPDATE:

I went back to the 1.377v bios, wasn't satisfied with the clocks i was getting with the non volted bios.

I'm going to try out 860 1251 but so far, i havent been able to hit high clocks.

I think it's the cooling. God knows what kinda glob they put under that headsink on the GPU. and the thermal pads on the ram modules might be causing problems too. A direct contact with that copper heatsink and some AS5 should seriously improve the results.

It has for my x800GTO, and my x1950pro in the past (both agp HEHE)

ALSO: Card is NOT stable above 60 temps...not when oc'ing anyways.

ty for being the brave soul to flash using the 1.377 bios! We just need to verify it actually is increasing voltage, though I do not know of measure points.

Once I get back home tomorrow from Thanksgiving break, i'm going to modify the bios and try running 1.4v. It should be pretty easy to tell if it actually is feeding more volts to the gpu if your temps under load are higher than the same clocks on the stock unlocked bios.

As far as cooling, there are ton of good coolers out there. Anything that fits the x1900xtx should fit the 3870/50 perfectly. TBH, the stock thermal paste job looked fairly decent when I removed the stock heatsink and replaced it with an Accelero S1 a week ago. The problem is the size of the heatsink. You'd think that a dualslot cooler would have a beefier heatsink, but that thing is pretty measly.

I must be a fortunate one because I am able to hit 877/1314 artifact free and run up to 905 core on Fur. Can't wait to try voltage testing tomorrow when I get back

For good reason, two of them need to fit under a slightly longer shroud on the HD3870x2.
40C overclocked max load with the R600 HS?
Made a post about it the other day.

AMD designed the heatsink so short but dual slot due to them planning on putting two of them on the same PCB. HD3870x2 has the exact same HS as the HD3870 but has two of them on there, obviously and a longer shroud and larger/different fan.

HD3870x2
HD3870
And HD2900XT just for fun.

Now think of how awesome that cooler would be if they hadn't designed the actual HS to be so short and could actually take up the entire/majority of the length of the card.

does anybody has or know where to download the GEcube OC version bios

so far
theres the MSI oc version bios on mkvtech.

i prefer the older bios
its more reliable on crossfires

Don't get too excited about the core settings. yeah they'll run certain apps fine and 2d mode flawlessly but the second you try to play a seriously sensitive game (nfs carbon), it all goes to hell. well it did for me anyways.

I'm using GEcube's HD 3870.
Is it not recommended to use an MSI BIOS on GEcube?
Because for the hardware itself there seems to be no difference at all even with all the distributers...
Looks to me that every BIOS is compatible with any distributer's product as long as the hardware itself is the same stuff.
Maybe not... not sure about the BIOS...

[Lightman]

1.377 BIOS did nothing to me, except screwing CF clocking
I'm back on original one....
