Another newbie here. Put my rig together last week, also my first time water cooling.

338

Got the card up to 1210Mhz stable with 1450mhz memory. maxed the temperature out at 42 during stress test while also stressing the CPU to determine how effective the water cooling would be on the same loop (am planning to Crossfire with a second 7870).

Am a beginner so will still have tones of tweaking to do but hoping to get pretty high.

Using the "Gigabyte Radeon HD7870 OC HDMI Dual-DisplayPort 2GB"

Dead Island, Fuel, TDU, TDU2 keep the card at 65-70 percent. Skyrim also does not max the card. Frames are ok, since i'm not noticing low drops, and they mainly stay above 60. Don't think that a CPU bottleneck is the culprit, because in my case the 2500k is running at 4,3GHz.

I think this is normal in these types of games. They aren't that demanding. I'm getting like 60% usage in Portal and 300fps.

What worries me are games like BF3 or Crysis 1 & 2, in which I'm seeing drops to 80% GPU usage.

I believe Skyrim is a very demanding CPU game. I notice that in towns my GPU usage drops to 50-70%, but outside hits 90-99%. And I'm also getting 60fps. So I won't worry for this game anymore.

BC2, on the other hand, is getting such a low performance. I don't get it, since this game is almost as CPU demanding as BF3.

If they would even take the time and money to check...

They can't see it.. programs like AB and GPU-Tweak don't save settings on the card itself. And even if they did, XFX would still have to send you a new one upon RMA because you stayed within the boundries of voltages provided by XFX and AB/GPU-Tweak.

Thanks!

Then tonight I shoot for 1350/1550. Maybe.... Just maybe I can hit 1400.

I finally bought a sapphire 7850. Soon I'll post some screen-shots in order to enter the club, but first I wanted to stabilize my overclock.
There are a number of quirks happening.
I used 'ASUS GPU Tweak' (v2.0.8.3) because it seams to be the only tool I can use that gives me higher then 1050/1450 core/memory frequency sliders

(I noticed that many here had the max core clock to 1050, so this is how to do it to get more: In 'ASUS GPU Tweak', you have to press a small 'Advanced Mode' button in the buttom left of the window, and then in Settings->Tunning you'll have the option 'Overclocking range enhancement').

It also has a voltage slider that has the max value 15mV higher than stock (my stock voltage is 1210mV) but the slider didn't seem to do anything, as the built-in monitor, and gpu-z reported the same voltage (so if anybody modified the voltage on a 7850, any help would be appreciated).

I've been using Kombustor 2.3 for stability testing and the other weird thing is that when I ran GPU Burn-in test on DirectX 11 with Post-FX, and after that I ran Kmark Stress Test the scene appeared yellow-tinted and with some vertical lines. First I mistook this for overclocking artifacts, but it seams to be consistent (if I first run the burn-in without the post-fx option, the yellow tint is fixed). Which test/option is better to run to ensure stability? right now i'm around 1120Mhz core clock and 1520 (x4 = 6080) memory and stress testing.

edit: In kombustor that is just non-intuitive interface, that tint is the post fx. It seems that the burn-in test is better for gpu-core stability testing, and the kmark stress test is better for memory (possibly because it uses more memory)

Another issue is with BOINC, when boinc-ing, the gpu load stays kind of low, high 70s, low 80s. These are probably driver issues that will be resolved with catalyst 12.4, as i've also seen that gpu load reporting is sometimes not working properly, and i'm not the only one: like here (see afterburner shot)

Maybe some one here can help me....

Iv got the clock up to 1210 on my HD7870 and under stress tests its stable and fine. However when i go to benchmark it at anything over 1180 the benchmarking software crashes and an error comes up saying that the graphics card has been removed... DxD11.exe or something so im guessing its DirectX thats having issues... but is this a driver based issue or is this the overclock??? if it is the overclock then why does it run so stable under stress tests????

Probably a really beginner questions but why not....
ASRock Mobo shouldnt be too much of a problem, 1000W power supply so power isnt a problem, and water cooled with a max temperature of 42 degrees so overheating is not a problem.....
Am rather stumped... is it just that my card is limited to 1180? or that the drivers are limited to 1180?

Any help would be greatly appreciated

Most of us haven't been able to achieve over 1200 on stock voltage.

My XFX was able to bench at 1225 on stock voltage but that was far from stable.

Your card just needs more juice to run over 1180.

When you say more Juice does that mean manually adjusting voltage??? or the card lacks the processing power to go further???
Sorry for the nubby questions, and slowly doing research on the issue but i do not understand the problem completely.. >.<<br /> Could you mean that the card is not drawing enough power at that speed which is why its "Disconnecting" as the card disconnects when it doesnt get enough power???

Thanks for he help btw!

Yes. You need to increase the voltage. MSI Afterburner supports voltage control. If you go beyond what the card is capable of at a certain voltage you will either get a driver crash, artifacts, hard locks, etc. Increase the voltage with AB if you feel like going further with the card.



On another note, unfortunately it looks like 1310 is the highest my core clock will go at 1.3 V.

I am disappointed; I felt it had at least 1350 in it! But, I guess I should be happy since most reviewers were not able to get above 1250!

However, at 1310/1450 the 7870 scores @ 7966 in 3DM11 graphics (performance). This is better than the reference 7970 (stock) @ 7600!

Also, for whatever reason my physics score in 3DM11 has decreased by about 300 points! ***! I am guessing instability but... I have had 0 problems since my last attempt at a moderate 4.5 OC. Any suggestions?

Nice purchase! I love mine. Enough to replace my computers with all new ones lol. Cant wait to get them with water blocks
