Thanks :)
Yeah, since I raised VTT a little, it works. Not sure whether 1380 or 1360 ram is faster, kinda depends on the App I'm benching too.
Hey sorry if this is a dumb question going to make the switch over from my dual gtx295's to dual 5870's. Is there only specific brands of card that supports voltage adjustments through afterburner?
Nope.. works on all of them ;)
As long as they are reference design of course.
I just saw this non-reference XFX cooler on a 5870 at my local retailer. I've never seen this one before, is it exclusive to XFX or is it a new variant of the reference design?
Looks like the Vapor-X cooler - same PCB layout, different cooler.
reference design or MSI :DQuote:

Hope so. If you look at the rear of the card it has the same shroud design as the original. It's almost identical, like they have simply moved the fan. Let's hope it's a new reference design, I love it! Much prefer this one to the original, and it should be quieter to boot. :yepp:Quote:

Gtx295 single pcb heatsink works wonders same design.
I have a Sapphire HD5850 BBA. The idle temperature of VDDC is 34C.
Can play any games @1030Gpu/1250 with no problem, just in Furmark VDDC gose to 120C and freeze.I keep fan at 100%.What should I do?
Don't use Furmark?Quote:

Will there be a very large boost in performance to have the ability to enable the physx functions in games? Another thing is, will there be any difference in performance by using a higher level Nvidia GC. Example, 9800GT vs 9600GT (because 9600 dirt cheap right now) or GTX260+ 216 vs 9800GT
Hope what I'm doing will worth the spendings.
Just got Sapphire 5850 and flashed to MSI BIOS,
after installing MSI Afterburner 1.5.1 I can't access Core Voltage slider, it is all greyed out. I've tried setting Core control in settings and even using that MSIAfterburner.cfg file to enable overclocking but no go...
Latest drivers 10.3, Windows 7 64-bit.
Any ideas folks?

Why not you change with RBE in BIOS the slider's maximum value for the GPU and memory and after that use the MSI Afterburn to change voltage.Quote:

Right now I have set up overclocked profile with Afterburner but it changes to it only when Afterburner is running, if I turn it off than card enters default 3d clocks when I play a game (checking with gpu-z). How do you guys make overclocked 3d profiles?
I think Afterburner has to be running for it to work properly, but I'm not so sure as I can't get it to really switch profiles automatically like I want it to, it pretty much stays overclocked until I change it myself.
Is it still possible to increase voltage using RBE? even on non reference cards?
Is there a convinient way of having 2d and overclocked 3d profiles switching as needed and such.
I'm sure someone has mentioned this and I will again for new people. If you're running Crossfire and getting locks/freezes with MSI's Afterburner it could be because of ULPS. I have to disable that to OC my cards with Afterburner otherwise I'm stuck with the CCC's OD. Also Crysis will lock at the menu with ULPS on using Crossfire for me. Seem like it switches cards 2/3 off then.

Switching it off and on is easy, just change the value and restart.
Yes, you can use RBE for this, to do this you need to go to the Clock Setting tab of RBE and click the "GPU registers" button under Voltage Registers.Quote:

Then edit the "Clock Info 00" settings to your overclock settings, but LEAVE THE VOLTAGE ALONE. Just leave it at the default, it should be 1.088V.
Flash your card, and your card should clock to 157/300 unless you're running 3d, when it will run your overclock.
If you want to be a little safe about this process, you can first flash just the voltage register and leave the stock clocks, and you can test to make sure your card is properly setting the voltage under stress.
been looking over this thread. bout to squeez trigger on this sapphire vapor x 5850. I read some comments on egg and another site, that recently the pcb was switched over to one with weaker vrms or something i forget. Im looking to do at least 950 on the core with stock voltage, not interested in flashing a MSI or other bios onto the card.
anyone know if this revision is decent

Can you raise the voltage of XFX HD5870 XXX, model with fan in the middle?
Why don't you download afterburner and see? :DQuote:

Compared to overclocked GTX295 with i7 4Ghz in Crysis bench 1680x1050 veryhigh, the GTX295 leaded by with 56.9FPS avg, followed by 5870 1Ghz with 50.3 fps avg.
This volt thirsty sucker needs 1.35v to be rock stable at 1Ghz on GPU tool artifact scanner.
