Asus Matrix HD7970 Platinum Review and Post-Your-Overclocks Thread! - Page 10

post #91 of 97
Think I got a bad card...Currently I cannot run any games at 1080 above stock. My Max at 768p was 1230/1750, but voltage didnt seem to make any difference. To make matters worse, Im currently sitting at 70C running WoW 1080p on Ultra (all settings maxxed), and HW Monitor has my idle temp at 40C with an ambient of 28C.

Is it true all 7970s are now Voltage locked, as Ive heard conflicting reports about this, and even caught a complaint on the ROG forums that ASUS now only allows 50mV of OC on the matrix.

All the reviews Ive seen of the Matrix Plat showed 1080p Ultra settings on modern titles like BF3 and Far Cry 3 with 1300/1750 at 1.35v and pushing 80+ FPS, and it was this performance and OC freedom that pushed me to choose the Matrix...Im just really disappointed atm and hate having to do RMAs...any thoughts?

Well running at 1300mhz, and 1.35v might no be the best on air, not all the cards do reach that OC stable, I have one and i usually game around 1260mhz, since it is the most stable and is doesn't get as hot. It will depend on how aggresive your fan profile is and your case airflow; make sure you have the latest drivers and the latest gpu tweak from Asus. These cards have a reputation to fail quite a lot, so you might have to RMA, I know mine passing 65c starts artifacting when i OC past 1250mhz. I hope this helps.

I use matrix with ares. Makin ares stable. Solo matrix use also so I can add my pci-e soundcard. My sweet spot for games is 1122/1650 for matrix only. With ares (tri-fire) it seems to be 1100/1600. http://www.3dmark.com/3dm11/6534423 was my winning result in Summer Assembly (no contest rly so easy win).Still nearly 13k thou it should be more. I know my cpu is keepin me back (8350) but aint switching teams at this point. Will c when it comes time for new gpu's.
Used core clock @ 1240 / memory 1651.
I could have pumped more but at least my Matrix kets to trouble when memoryclock goes over 1750 or core over 1325.. At least for my card I've came to conclusion to keep it under 1250/1750 when tri-fire. Solo card can go 1350 but keepin memory @ 1750.
Bad matrix mayby.. Dont seem to get past 1800 on memory clock with matrix. Tri-fire pushes Matrix even more down.. To max memory clocks of 1250. Ares has the power to go faster but its unstable as h... Tri-fire has fixed the problem for me (1 month+ good behavior from my rig) so no artefacts or flickering.

Btw. I also use either Sleeping Dogs (seems to crash if unstable clocks, Or crysis (duh).
Using mixed oc tools but seem to be gettin best results by removing gputweak etc from my comp and usin CCC for the clocks.
Enough jada jada from me.. just my ..2 cent I think rolleyes.gif

I ended up RMAing, but seem to have similar issues, not stable past 1175/1750, but the temps are back under control...Im considering just returning it and getting an MSI Lightning BE 7970, anyone know if they OC well, or can beat my Matrix?
post #95 of 97
Lightings dont have Dual Link DVI outputs - so if you ever want to get a 3D and/or 120hz and/or 1440p, you wont be able to. Id just return it and get a cheap HIS ICEQ2 or Sapphire for ~$300. I picked up a 2nd IceQ2 for $295CDN to pair up with my Matrix...the thing overclocked to 1175/1575 stock voltage with no problems at all. Kinda sad i had to return it.

At this point, spend as little as possible as they are about to get obsoleted in the next few weeks.

Yeah I dont really care about the DL-DVI as I planned to go DP...and 3-D is a horrible/failed gimmick imo.

As for obsolete cards, I keep hearing the 8000s are reboxed 7000s, and that 9000s are not due for at least a year, but maybe Im wrong (swear Ive seen tons of people saying that 8000s are coming so save your money since early 2012 tongue.gif)

8000 are the rebranded mobile gpu, theres a new naming convention for next gen - Radeon R9 280 .. http://www.ign.com/boards/threads/amd-next-radeon-gpu-to-be-r9-280x-specs.453357523/

AMD posted on their facebook page that theyll have an announcement on the 25th (next week) https://www.facebook.com/AMDGaming
