Why the high clocks put out by... for example the Toxic or even the gigabyte one (what ? 1100 is solid if you ask me) are the safer way to go, as you can buy a DCU2 or even a matrix with its absurdly high price tag and not be able to get 10 mhz more off it. That will leave a bad taste in your mouth.

@Ashuiegi

I've finally found stability in CFing my Matrix 280x. Could you tell me what needs to be done to play with GPU Voltage? I can change anything in GPU Tweak but it always stays at 1,2560 in Stress.
post #493 of 9745

What is max allowable voltage for the MSI r9 280x gaming?  The ASUS 280x nonmatrix  is 1.3.

Hey.

Picked up a DCU II Top - it's been over 2 years since I OC'd a GPU, so I'd really apreciate some software/technique pointers.

1. What's the preferred OC application please?
2. What's the best testing app? Still Furmark?
3. What's the thing I've been reading about re: getting the CPU and MEM frequency to be in a particular ratio to one another?
4. What's the highest safe temp of the DCU-ii?
5. What's the best way to control the DCU fan? the profile is a little agressive at stock...

The rep fair will visit those who help biggrin.gif

I got my Matrix to 1200 with memory still at stock for the moment. Ran fine with no problems.

I ran 3dmark11 with cpu 4.5/gpu 1.2 and got like 50 points shy of 10k. My graphics score was well into the 11k range so I know my processor is holding back my overall score. I took a screenshot and will post it later. I have not had time to push things and test properly so I have not done so.

You can use MSI afterburner or Asus gpu tweak. Many use afterburner for sure.

1. MSI Afterburner for me, it's pretty popular
2. Furmark is overkill, Heaven or Valley is better for making sure you'd be ok in a game. But some games can vary and may cause a crash where other games won't.
3. Don't know
4. Around 100c is still ok, but you'd normally want these cards below 90
5. MSI Afterburner can do that too

1. The software comes down to preference since they all are pretty much capable of the same results. I prefer MSI Afterburners but Sapphire Trixx and Asus GPU Tweak are also good alternatives.
2. Furmark is a great stress test but Unigine Valley can also be used to test stability in addition to running any games that you play.
3. Are you referring to the GPU core and Mem frequencies? The ratios are more important for mining, you should focus on the core clock first and then move to memory once you find the maximum stable core clock.
4. I wouldn't suggest higher than 85C for real world scenarios (gaming).
5. OC software does have the capacity to set your own fan curve.

Gigabyte R9 280X Windforce 3 Edition @1150 core, stock mem and cpu

http://www.3dmark.com/3dm11/7350764



Considering that's just a 50Mhz bump I'd say its pretty damn good.

You should OC the memory to ~1750MHz
