Guys,

unable to get screen capture to work on my rig.
Anyway, using 1080 hot about 52XX.

Its okay bros...

A room heater - 295x2 crossfire.

Ok thx.
will try later.
Catalyst not stable with 4 GPUs I think, esp on samsung ud590.

hoping the future will be better....

Thanks for the tip.
However using afterburner at the moment it is not as stable, still trying to get the best settings for the current spec.
Will try using the hp tonite, if not I am happy anyway getting above 5k for heaven 1080.

Cheers

Thanks man, cost me a bomb and a lot of heat in the room.

But got my rig in the 3dmark hall of fame ..go Malaysia go!!!

Hi guys,

quad GPU comes with a lot of price to pay other than the initial dosh to get it...electricity bills, heat, unstable drivers, games not running (Crysis 3..) and flickering in certain games, and worst ...benchmark crashing mid run. I only had been able to run 3DMark13 with the new update but now, heaven and valley is crashing mid run. It was better with my 780 sli..
Will try to sort out today..and post results.

Cheers.

Thanks man for the advice,

I had thought long and hard before upgrading the card, PSU actually is my focus then.
I have a CM V1200 90+plat powering my rig and one 295x2. should be no problem as it is quite a normal build, 4770k, 16gb RAM, SSD and 2 HDD, and 10 fans.
I have a SST 1200w 80+gold powering just the other 295x2, started using the green to black pin trick.

I doubt that power is a problem, it is driver issue and a big one.
Very little info available running this two cards in CF as each have its own PLX chip on board, thus I think some drivers optimization is required.
I saw 290x quadfire running well, and I think that setup has one advantage that all of the GPUs are connected via the PCIe bridge (with or without PLX chip).

I will post once I can actually finish the benchmark without crashing....

Good day...

Thanks man.

As I said power should not be a problem, both PSU are single rails 12V able to pump 30A per cable.
AMD put the spec very high because they are overpowering the PCIe power specs.
They list 28A minimum per rail (or cable in my case), and minimum PSU 850w per card.
Reviewers on th net are running ONE 1500w PSU for 295x2 quad , just like me --I should be more than okay.

Cheers anyway.

Just ran with updated rig, 1080 score 4718.

Cheers.

Boss,

using the new Omega driver ...Score is down a bit to 45xx. But seemed more stable.
Pics as evidence enclosed.

Thanks.
