When I get 10 mins I will turn it off n do a run and then turn it on and do one to compare temps.
No fan I used get bout 50+ with the fan on full it's low 40s

Okay. Perhaps some of the differences due to fact you are on Thuban. Vishera is the hottest processor I've ever run. Otherwise these numbers are close enough for gov't work.

Success! I finally got a stable 4.8GHz Prime95 run for over an hour.

BTW, since the topic of turning off cores has come up, I will state for the record that Core 5 is the weak sister on my 8350 based on it being the first core to typically drop out when running Prime95..

To achieve this run, Vcore is set to 1.4935V, LLC is set to High for CPU and Regular for CPU/NB. In the image, you will see the degree of Vdroop under load, which is pretty substantial.
The NB has an 80mm fan blowing on it to achieve the temps shown in HWMonitor. You'll see the package or coretemp as being reasonable. All case fans were running on max.

My next goal is to shoot for a 5.0GHz Prime stable run.

There is still one issue I need to troubleshoot, and if anyone else has noticed this, please jump in. What I'm noticing is that the key to stability is stable CPU voltage. When I tried a few runs with LLC set to Ultra, and many others are stating use of this setting for their stability claims, my system locks up/freezes instantly when starting Prime95. I'm being careful how much voltage I'm putting into these runs because otherwise the heat tradeoff won't work. I probably have to jack the voltage up a bit higher to ensure stability, but there may be some other setting I'm overlooking. Also, as Asus still hasn't had a lot of time with Vishera yet, it's possible some upcoming BIOS update might address problems like this. post-flame-small.gif

i let prime run for 4mins (forgot show it running but it was) and took the screenshot which had hw monitor running, without the fan i would be up in the 50s but i stayed at 39c the whole time.


the opt 3 temp is a probe placed ontop of the nb heatsink bent into a \___ shape to hold istelf between the fins (probes that come with board) and it doesnt move in temp nor the nb temp.
the fan is running of the cpu header and so increases as the cpu temps increase.

how have you got the fan laid out can u put up a pic.

yea this chip is cool as a cucumber compared to some ive seen

Okay, Right now if you can look at an earlier picture and imagine an 80mm fan sitting on the EVGA GTX 460. This is a temporary solution until I can find a smaller fan that has the right cfm characteristics and can be properly secured. I'm still upset Asus did this to their flagship AMD board.

As for your data, this is night and day if you compare voltages and power consumption.

weird.... i never had this with ultra LLC..... but if i use Extreme LLC ....i have the same Freeze @ IBT launch...each time

As for your data, this is night and day if you compare voltages and power consumption.


i agree where 2 worlds apart on voltages and hardware setup but i was just showing that it can be kept cool and sharing the results i had found. i had the crosshair iv extreme which did come with a nb fan but was useless as it was hidden behind the heatsink assembly so that could be why they didnt do it again
http://www.newegg.com/Product/Product.aspx?Item=N82E16835119050
this is close to the fan i used and its noisy under full pelt but when set on standard using asus fan expert its quite and ramps up when the cpu load goes up.
i would get a cheap one and hook it up to the mb for it to control it aslong as its silent you should be ok. being 30mm thick i used a screw from a antec 620 rad to hold it in place and it doesnt move. if you were in the uk or near i would post you one as i have about 6 of them

i have purchased 2 gskill ram coolers 1 for my ram and the other for the nb and vrm section i just need to mod it abit to fit between the fins so i will see if this is any better

And I've seen that too. It's possible the power surge is overwhelming the PSU. I will work to investigate this further. There are some other settings in the digi-vrm subsystem. Perhaps those need adjusting.

Call a spade a spade. They just cheaped out. Using a NB fan assembly would be counterproductive with an Aircooled CPU. But since these boards are used by OC and thus WC enthusiasts, the NB cooler is very much a necessity.

Will the ram cooler fit under the H100 hoses? I suppose I could reorient the radiator. Can you provide a link of which ram cooler you picked up?

A ramcooler seems like it would be far too large to be a fit in that NB area of the board.

2 of these. You could cable tie the hoses and use another to pull them toward the board abit.

I think it will fit On yours you will have to bend the lips out on the bottom of the coolers legs to go on the NB hs.

If you get around to installing one of these on your C5F for the NB, I'd love to see how it looks. Sounds like you'll be all set to add an 8350!!

I'm going to make a run to a Tigerdirect store in reasonable driving distance to see if they have anything like this. If not I will grab these from NewEgg. I'm also interested in the RAM application since I've noticed the Snipers get hot to the touch under load.
