More clocks, where will it stop!

[OC Nub]

Thats a pretty awesome card you have there!

Ordered a full cover block for the card. The EK blocks were sold out, so I went with the Koolance. http://www.koolance.com/water-coolin...oducts_id=1239

Trixx best to overclock, but lacks some of the things MSI Afterburner has
vmem an hardware monitor

You do not need to use vmem in msi Afterburner so slow you can run mem in afterburner

Trixx cannot compare to Afterburner in any way shape or form, AB is miles ahead, with new beta 11, you can now control 3 seperate voltages for better overclocking.

I'm not the guy you were referring to but if it helps my card will do 1225/1450 (haven't tried higher on the mem) at stock volts. Default voltage is 1.049V in AB and 1.175 in Trixx. Voltage control is unlocked in AB. The two numbers you asked for are 00000174 and 00003510.

Elfear,
If you don't mind pushing the voltage, can you test your card and see if you can do 1.25-1.3v on the GPU core (doesn't matter which core clocks you use, even stock, although try your 1225 mhz) and see if you are stable?

Someone with a 1.05v Vid card who could do 1200 mhz at 1.175v said that he starts artifacting if the measured vcore goes above 1.20v in AB.
BTW after hours of BF3 last night, seems like I can do 1225 @ 1.237v target on the core, without artifacting in planes in BF3 (Afterburner said the voltage was 1.17-1.18v measured). 1200 is fine at 1.225v target (1.16v real). 1250 mhz requires at least 1.275v target though, and I won't try that (was artifacting in BF3 at 1.250v target)

Your link is to beta5.

Like a dumb ass I dld and installed beta 5 lol. It does have beta 11 at the top in the download list though.

[OC Nub]

Was able to get the memory up a little higher with afterburner beta11. Max mhz allowed in beta11 is 1790 it seems.

guys be aware that on latest betas 10 and 11 of MSI Aftb. i reported errors to the author of it
i normally just overwrite the old one, this time i didnt and start getting heavy errors on GFX like this



it was over and over, so what i did was remove MSI Aftb, remove drivers, restart reinstall drivers and then MSI Aftb.

this may or not may happen but for you guys that bench is primary so i would put and eye on this

cheers to all
Sergio

Thanks for the info.

To get mem any higher, I used afterburner and set voltage, closed it and set clocks with trixx, 1835mhz so far in heaven extreme preset.

but beta 11 works with 7970's now check

I used beta11, but maximum memory frequency it allows is 1790mhz. Trixx lets you go higher, so I used it for settings clocks.

yes i told real 7 to do it and same, seems they have to polish the beta more

[Martin.v.r]

it will only cause problems trixx and msi Afterburner, they can not work together, have tried for 2 days, perhaps 1 a 20 times it goes well.
ned at bios tool to edit it whit

BF3 an 3Dmark is bad whit AMD Catalyst 12.x (8.95 January 03) Unofficial BETA

For benching it has worked fine. Set voltage in AB, save prifile to load at start up. After start up, closed AB, open Trixx, set clocks, no issues.

[CplWolverine]

Is there any way at all to check the expected VID based on serial numbers, or is that a stupid question? :P What are these two numbers I've seen mentioned in past posts regarding the 'theory' that the lower VID chips of course clock better.

[the_real_7]

with a little messing around i got msi ab working did 1213 clock / 1375 memory , this card just has major push , damn i could just imagine with good drivers and some water-cooling , what they would do , truthfully i think crossfire is overkill with these , so lets hope another crysis type game come out

Good call on the voltage. Tried running through the STALKER:COP benchmark with the same clocks (1225/1450) but with voltage raised to 1.25V in TRIXX and got an almost immediate crash. Benchmark runs fine at stock volts.

I wonder if it's OVP?
I was able to put my 1175mv Vid card with set @ 1.250v in 3dmark 2011 without crashing, just to check (clocks at 1200, didn't crash; btw it's stable at 1.231v target for hours; 1.225v eventually caused a "cannot initialize full screen: make sure no other apps are running" error after about an hour. Heaven was fully stable at 1.231v too, for an hour, but got up to 88C, with room temp at idk, 86 degrees fahrenheit).

So the lower Vid cards can't take as much voltage, but clock better on less?

[Martin.v.r]

1175mv an can run whit 1.3v 1300MHZ on gpu

Falkentyne how you guys finding your vid . on my card i start artifact after 1.250 volts , 1.3 is just crash city , but i havent really work on my core with less volts so that might be the ticket , to keep from artifact so early on , I would for sure like to hit 1300mhz , but a stable 1200 seems to be the spot with out better cooling

We'll find out if it's VRMs getting too hot after I get my waterblock tonight. I'm really hoping better cooling will solve the issue because I don't want to be stuck at 1225.

Guys which driver are you guys using for stable gaming with this card in Tri Fire or Crossfire??? Also any of you got afterburner to allow clocks over 1125. My cards do this at stock volts.

Afterburner beta 11 will set the default volts for your card based on its ASIC binning level. So you can see it in the voltage monitoring.
There have been some rumors going around that the cards will crash if you give them more than 125mv over the stock voltage. If this is true, this could be why people with 1.050v Vid cards are crashing as soon as the card hits 1.2v of "real" voltage (happens at about 1.25v of target voltage, with vdroop). And would also explain why people with 1.112v Vid cards can't use 1.3v target voltage. This needs more testing.
