Bootsy is it suppoused to say (unsure on vista64) ?
Hmmm, I can get 890/1225 stable for 24/7 :\ But with the standard bios.
You have voltmod or not?Quote:

Acording to ATI control Center the best OC for my 4870 is 830 / 1150 but when I test it with ATI tool with by scanning for artifacts it doesnt go any further than 2 seconds before it gets small yellow artifacts. I currently have my card at 820 / 1050. RBEditor wont leave me save the bios at 820 / 1090 where my best oc is after testing with ATI tool.
Is there some other software I can use to test the OC stability?
Well GPUz always says that, even when I had a pair of 3870s in crossfire.Quote:

I will Pencil mod to 1.4v later when I install the WC. What the Max safe Voltage you can use on WC ?
Umm, this is 4870 BIOS and card.. sooo, I'd rather not do it if I were you :)Quote:

err didnt notice its a 4870 BIOS :|. Thanks you just saved me a card.
yes, as you remember in the first versions of gpu-z, cf status was often displayed as disabled even though it was enabled. i think i got it almost figured out but there are still some problems under vista64 so i'm covering my ass :)Quote:

this a direct copy and past of the email i recived from ati tec center.
"Here is your new bios for HD4870OCX-512MBs at 795MHz-1100MHz and Clock Limitation is 990MHz-1250MHz. Also, this bin has been modified the voltage’s setting as well so it should be fixed on artifacts issue for certain motherboards. I ran a test via 3DMarks 06 for more than 2 hours with the new bin and did not see any artifacts related.
CLICK HERE to download an EXECUTABLE file…
http://74.62.199.69/ATIHD4870512MBOCX795-1100MHz.exe
1) Run "ATIHD4870512MBOCX795-1100MHz.exe” under WinXP/Vista
2) Click on “UNZIP” button to begin
3) Let it run through the flashing progress and wait for a confirmation message then restart your PC and Don’t forget to send us an e-mail for the result. Thanks!"
Well lest go guys and see if this is the golden one!:)
@ IRONBMAN,
Awesome! That was the easiest flash I've ever done. Right from windows (Vista 64) and it flashed it no problem! 990/1250 in CCC!
holy CraptacularOne how much of a volt mod and cooling did you need to hit 900/5000? That's just insane.
Believe it or not it's on the stock cooler, and that was with the ASUS bios.Quote:

Now, I flashed both the cards and they can simply be set in CCC!
So it's on stock volts? What brand?
Earlier on Asus cards were showing good hittings in the 850 area and some on here hit 875/1200 with a sapphire card.
Trying to figure which brand has the best chance of max oc/performance....so far data seems inconclusive.
Mine are Visiontek cards. So are My 4870X2's.Quote:

990/1250 is upper OC limit in CCC
fans same as on reference boards/bios, so you still have to adjust it.
If you extract this exe to a folder, you'll get a file that is BIOS itself, and you can open it in RBE 1.13 with no problems.
Sorry if this is a daft question but does this bios give extra voltage to the cards then or not?Quote:

Tested with my Sapphire, no improvement in max OC whatsoever.
I've also checked the voltage with a DMM and I don't see any difference compared to my stock bios @ 1.263V :shrug:
They are on stock voltage and the stock cooler :up:Quote:

900/1250, no way, not unless you lucked out to get the two best cards that ever came out of an ATI shop, and I mean EVER.
Anybody can set clocks, it's running them stable that's a challenge.
Proof with ATITool artifact free, FurMark, or 3DMark06 TBT, and other benches and pics or it never happened.:yawn2:
Edit: What's more, the current top score on ORB for Vantage is about 10500 per GPU (21k overall GPU score) with two specially donated ASUS cards, custom BIOS, and LN2 cooling. As I was scoring ~9500 with a single 4870 at 850/1150, you must be scoring at least comparable if not higher than the current top score there is but on stock volts with stock cooling. Sorry, I just don't buy it without major proof.
