Wow, very nice matrix score..if I use 3770k @ 5.0GHz for this bench hehehe ...my suicide run with R9-280X DCU2 Top, 3570k @ 4.9GHz
1265/7100 on air, fan 100% A/C room...might wanna try higher core but Max Vcore only 1263mV so I guess no more room left ..but hey no artifacts observed

^^ not bad at all... I believe 280X Matrix and DCU2T will go higher with water

possible to change its chips to oc?

Ya, no doubt bout that..maybe later will do WC for GPUs only, gaming at 1220MHz/1700MHz Far Cry3 1440p ultra +4xMSAA so far no problem 2hr+..nice card indeed

no idea but i'd rather not do that even if it's possible if jutst to OC..not worth it, somemore where you can get an extra chip by itself since we're just end user?

^wow. really nice OC by both of you guys. i can't even get past 1250 cc without artifact .

With a good temperature < 55C you will not get the artifacts.
Watercooling make it possible.

But my artifact occur even my temp is juz 70C which i don't think is high enough to cause it.
V at 1.3v. as well board li-on +20.
i assume the chip has hit the wall at that clock

I dont think it hit the wall already bro, once you put on waterblock and temp stayed below 55deG under full load, pretty sure that those artifacts will gone for good. I've tried on few of my prev 7970s where the graphics will start to artifacts once temp exceed 56-58'C on high OC but when I put on waterblock it is gone..same clock,same voltage but at different temp

whoa. means to get the full potential/wall of the gc, it needs to be under <55C
thxs for the great info. change my perception on the gc oc ability.

my score for R9 280X. no aircon. air cooling.

but the memory is at limit already, broken polygons from time to time but managed to complete the test.

, your score even higher than mine at 1200MHz? Because even your cpu clock also lower than mine so its kinda weird that your score higher than mine unless diff driver used...may I know which driver you're using in this test bro? is it latest catalyst 13.11 beta8?

not beta 8. i also donno which beta version. all i know is 13.11 when it was made available.

also I'm using Window 8, so I'm not sure if that one affects it as well.

anyone has a 7970 dc2T card?
i tried flash the bios to NON TOP which OCN member claimed it's unlocked voltage
so i can adjust the GPU voltage, but i got 2 different reading between ASUS GPU tweak and MSI afterburner
i tried rise the voltage to 12xx mv but the asus gpu tweak reading still stay at 1090mv max


Attached thumbnail(s)

Try radeon pro! Very good for testing oc with games cause u can use a overlay

Normal OC run. All at 1150/1500
pending to delid the cpu, hence the stock clock due to reachable 60C even with phanteks on it



@1200/1500

Just wondering as if anyone getting the directX "DeviceRemoved" error for bf4 under GPU OC circumstances.

note: Using single 7970 card (1125/1580)

I'm using 280x which is the same as yours..always run BF4 under High OC and never encounter that error, have you try update to latest beta driver, directX also up to date?

Latest beta 9.2 has some serious stuttering issues and unable to revert back to older driver, therefore I did not give the update a try. directX is up to date. As I've researched, it's the OC issue that causing this error. Someone told me that the MSI Afterburner doesn't engage 3d volts in BF4 due to 64 bit.

Maybe because I'm using Asus GPU tweak..give it a try, or can also opt for sapphire TrixX?
