post #211 of 776
Have anyone tried Virtu MVP yet? I downloaded the software today and I have to say I'm quite disappointed as it's not exactly what I expected. When enabled it does increase the overall score in 3DMark11, Vantage and Heaven over the one scored with the dGPU only, but it doesn't really make any difference in games. I was hoping that this would allow us to use a more powerful dGPU than the HD 6670 in a Hybrid Crossfire combination with the iGPU but it doesn't seem to work like that. Looks like the 30-70% FPS boost that was advertised it's just a myth.

So far the only A75 motherboard that is officially supported is the ASRock A75 Pro4/MVP, but you can get a 30 day trial for any A75 motherboard. If anyone is interested to try the Virtu MVP software you can download it at the ASRock website.

Ahhh sweet resurrection!!! So I thought I would make a worthwhile post (or so I hope) to the APU club.

Tonight I decided to do a little tweaking experiment. Undervolting. Now I know this may not be new to some, but for me this is really my first time really changing how the computer works. I was pleasantly surprised by the results.

The hardware used for the experiment are in my Sig Rig.

Now for the parameters of the experiment. All of my benchmarks were run using Prime95 set to In-Place Large TTF's running for 10-20 minutes.
Core Speed was 3090 MHz

My first trial was a baseline at 1.416v. A Prime95 run yielded core temperatures of 56.1 C across all 4 cores.

For Trial 2 I lowered the core voltage to 1.296v (1.300 in the BIOS). The subsequent Prime95 Run yielded temperatures of 41.6 C! For someone who has never experimented with this stuff I find that to a tremendous drop in temperature. Almost 15 C my lower the voltage by .2 volts!!

So I was feeling good and decided to run a third trial. I set the Core Voltage to 1.200v. Upon starting my Prime95 Torture Test I was greeted with a BSOD.

I then tweaked the voltage to 1.248v (1.250 in the BIOS). Torture Test churned out 36.1 C. A 20 C drop in temperature just by tweaking the core voltage. Amazing!

Once again this is probably old news to the more experienced tweakers but to those afraid to mess with your settings I encourage you to try it. I will be keeping a Google Docs spreadsheet of my progress if anyone would like me to share it with them.

Kinda cool knowing im going to get a graphics card with a 1 Ghz clock speed smile.gif

Just wondering, Would you say the 7770 is good? what are your experiences with it, I want to hear about the card from someone who actually has it, because ive heard that it's not a very good card, and from other people, ive heard its a great card. what are your thoughts on it?

I think it is a fantastic little card with great bang for the buck performance. Runs super cool, plays everything competantly @ 1080P and even overclocks like snot.

I have one in my budget dozer.

According to most reviews, it performs somewhere between the 6850 and 6870 but uses WAY less power and is very quiet. I'd say they are perfect cards for a htpc/light gaming rig. They are just priced a little high though. I'm sure the price will drop once the green team releases their own low power 6XX series card.

I think it actually performs a little bit under the 6850. I used one for a friends build and it was decent (especially because we got it on special for 120!) I have also used the 7750 for budget builds, and it is IMO the best perf/watt/price out. Simply amazing. Some people might call it too low end, but it performs on par (and even better) than the 5770/6770 (which I think is perfect for a budget rig) and it literally uses no power.

so i just got my internet back on lol :/ so how are things going with the apu club? Also is anyone getting the new trinity apu this year?
post #219 of 776
also another question is getting a radeon hd 6670 for dual graphics worth the investment?

Assuming you pair your APU with 1866 RAM, and can get HD6670 much cheaper than HD6770, yes.

Otherwise no. APU + 1866 RAM + 6670 = 6770 performance.
