Asus Matrix Platinum @ 1240/1775 - keep it?

post #1 of 41
Thread Starter 
Not sure if i should keep or exchange this Matrix for another one (i believe my local shop wil let me return/exchange within 7 days)

I'm at work so i dont remember the exact settings but off the top of my head:

Core Speed: 1240 or 1250 but anything after 1250 its unstable
Core Voltage: 1.27v (default 1.2v) - at 1270+ it doesnt matter how much voltage i pump it artifacts, went up to 1.35v
Memory Speed: 1775mhz
Memory Voltage: 1.65v (default 1.6v)
Fan Speed: Manual - aggressive id say, fan hits about 70% once 60C is reached
Power: +20%
LLC: 100% (i notice at lower LLC when it crashes, the voltage fluctuates a bit, setting it at 100% seems to stabilize)

Temperature maxes out at around 70C in Heaven, 65C in game play (tested using Crysis 2 and Left 4 Dead 2). Air flow is pretty good - i have 3 intake fans, one huge one in the side, 2 from the top and 1 exhaust fan at the rear of the case. Big CoolerMaster HAF-X case.

100% Fan speed is just too loud, i guess some people dont mind it..but anything over 60% and its noticeable.

Outside temp is about 17C (separate bedroom, cold)

Was really hoping for 1300mhz, at least 1275mhz, but 1240mhz seems kinda low for this $500 card.

What would you guys do?

Update: I've figured out how to "de-link" the core speed and voltage AND set both Fan1 and Fan2 speeds via GPU Tweak, these are my current gaming settings

Core: 1265mhz
Voltage: 1.30v (default 1.25v)
Memory: 1775mhz
Memory Voltage: 1.65v
Power Target: +20%
LLC: 100%
Fan1 and Fan2: 60% (Manual)
Temp: 65C Max in Crysis 2, other games about 55C

I use these settings for gaming only, then drop down to default reference speeds/auto fan speeds when playing old games like L4D2

Keep it. 1240 to 1300mhz is not going to net any kind of noticeable difference in FPS. Benchmarks maybe but games no.

Not worth the chance to get a worse card. Enjoy this one because 1240 is pretty dang good! thumb.gif

KEEP YOUR CARD. 1240/1775 is a very respectable overclock. Keep in mind that your card is overclocked from its reference clocks of 925/1375. Users tend to forget that. In total including the factory overclock, that's a 34% overclock on the core and a 29% overclock on the memory.

@ 1300MHz you'd gain maybe ~2 extra fps thumb.gif

^ Ya..but 925mhz cards are $150 cheaper smile.gif And my old XFX hit 1126/1600

But its ok cuz its quieter even at faster fan speed (reference fans > 50% is brutal) and it has an extra DVI out which i need for my 2nd Korean panel

I'm also kind of afraid of what the resale value is for this card would be - 3 slot, i think once 8xxx comes out a reference $370 card might sell for $250ish, while this $500 card might only get...$300?

I try to sell and upgrade every cycle if it makes sense

Ok leaning towards keeping it - just really wish it would do 1275+ ;p

any Tahiti chip doing 1200+ Mhz completely stable is not bad. i would definitely say its close to a golden chip. It might be a better idea to check at what voltage you hit 1200 Mhz. If you can reduce voltage to below 1.25v while remaining completely stable in games/benchmarks at 1200 Mhz thats the smarter tradeoff. lesser voltage means less heat and lower temps. easier to cool and lower fan speed / noise. Given that your chip can't hit 1250+ Mhz you won't be really losing much at all. keep the card and strike a balance. thumb.gif

I've had three 7970s before the Matrix Platinum; Sapphire 7970 OC, Gigabyte 7970, and MSI Lightning 7970. One of them was voltage-locked, one could not touch 1200MHz, and the Lightning could only manage 1210/1700. Believe me when I say; you are fortunate to have reached 1240/1775 thumb.gif

My Matrix can game at 1320/1775 but you know how annoying dual fans sound at 100%? I don't even run it at that 24/7. It's sitting at home, right now, at 1200/1600 and destroys every game in existence while laughing at competing cards[Keplers] biggrin.gif

Cool this makes me feel better - with LLC set to 100% and Power to +20% - i notice the voltage is around 1270mV when at full load - in software the voltage is actually at 1235 but i hit those hardware + - buttons on the card that increases voltage to the max (i find its more stable), so i think that adds around 50mV

I think i need another night of tweaking, hopefully bring the voltage down a bit more and have it completely max out at 65C

Theres a huge difference between 1250 and 1300. That said, even if you returned/swapped the card theres no guarantee you'll get a replacement that will hit 1300.

I have till Saturday - so my plan was to exchange, play with that till tomorrow - if its worse - either swap back or just save $150 and get a reference MSI which should be unlocked and live with the OC (hopefully 1150/1650)

From my OCing on my regular Asus DC2T 7970 bunch of bums with their matrixs making my card feel bad I have found that the OC is much more noticeable on higher res screens/eyefinity than in a single 1080 screen. I would also say that if gaming on 1080 I'm with them in trying to keep it with a low voltage as needed for 1200.

In my case I got mine to about 1175 and it was a really great boost from 1100 for my games and their mins which is big for me since I only use one card for 1440.
