For your interest guys I am doing a thread to show whether Vishera does or does not bottleneck a crossfire hd 7970 I have done a CPU and GPU usage graph for 3d mark 11, I found it very interesting... Interested to know what you guys think of the CPU usage compared to the GPU Usage at the same point

cool.

Whats the overclock and whats the hyper transport at? I've seen some people with crossfire pick up large gains by increasing the hyper transport speed.

Hey guys...ok so I got it stable at 4.5 using only 1.40625 volts with medium llc..full load volts like 1.32..insane...Howver I can't get it to properly pass ibt at 1.47. at 1.45625 its stable but the cores drop to 7x multi at around test 6 on ibt. temp is only mazing out at around 50c so its not that. whats causing the down throttling? is there another voltage I need to raise besides core voltage?

Note that the core voltage in your BIOS and the true readings are different. To avoid any further confusion, post the readings from a program such as core temp or HW Monitor thumb.gif

Also, go into advanced CPU configuration and turn off all of the power saving utilities such as Cool n Quiet, C1E, ect.

Hey guy

Have you tried using ultra high llc. Its much more better (for me at least) I got the m5a99x evo and medium llc is just like you insane vdroop. I found using ultra high settings is a rock steady voltage and you might even get to lower the vcore a little and i only got a 2oC increase in temps

Hey endevite

I did the LLC testing lol. I only did 10 runs IBT for timekeeping had alot of changes to make to get the lowest voltage i could over IBT rolleyes.gif

4.6 Medium LLC
Vcore 1.42
Vdroop 1.33 /1.34 high fluctuations in voltage
Max Socket Temp 60oC
Max Core Temp 53

4.6 High LLC
Vcore 1.40
Vdroop 1.34 Medium fluctuation
Max Socket Temp 62
Max Core Temp 53

4.6 ultra High
Vcore 1.36250
Vdroop no change in Vcore Rock Steady
Max Socket Temp 64
Max Core Temp 55

4.7 i couldnt get a medium llc on it. i tried up to 1.45 vcore and i wasnt prepared to go higher lol

4.7 Ultra high
Vcore 1.40
Vdroop 1.392 Rock Steady
Max socket temp 68
Max Core temp 59

Not sure if its of any use to anyone lol all the temps are on air cooling only vcore voltages changed and rest left on auto.

Thought it might help fellow newbies like myself what different llc settings do. Though im sure itll be different for different boards

Hey guys, looking at getting an 8350. One thing that I am looking at right now, is how much power it draws compared to the 1090T. Has anyone had a killawatt or anything hooked up to their computers to have some idea of what they are using?

I havent measured it but it should be about 20-30W at load.
