I don't really see it happening though especially in 256bit Ganged(a lot of Redundancy) but if it was 4x64bit unganged(Memory bandwidth goes down but Multiapplication throughput will rise) it might happen but I don't know
What , if any real benefit would there be to having Quad channel memory on a normal desktop PC ?

How does Quad channel improve a ram disk over dual channel if the quantity is the same ?

If it was 256bit Ganged quad-channel

692

You would see more bandwidth like for the X79 CPUs

If it was 4 x 64bit you would see if you had multiple applications up that require Data larger than 2GB to be moved to be less stutter

Since the current Bulldozer is 2 x 64bit (forced I believe) it is most likely we will see 4 x 64bit

Ever had problems stabilzing these chips with p95 ?

i have come across this ...

crosshair formula v bios settings....



DRAM VREF CA on CPU: Adjusting this reference voltage can help increase stability during stress tests - if rounding errors are reported above or below the expected numerical value (Prime95, Super Pi). If the rounding error shows a value higher than expected was returned from DRAM, then increase the Vref to 50.5% and see if it helps. The same principal can be used to lower Vref if the value returned is lower than the expected value.

The following pictures show how reference voltages interact with logic sampling:

450







450









Adjustment is recommended only after CPU voltage, DRAM voltage, CP/NB Voltage, memory timings and drive strength settings have been optimised.


I will be trying this out today and see what efect this has, this article is from ROG site

* im not responsible if anything goes wrong if you try this yourself*

i will update later today biggrin.gif

please +rep me if this helps ! biggrin.gif

Is there any benefit of the 8150 over 4100 other than extra cores/modules?

Need a quick answer. I can get the 8150 for 200 $. Is that a good deal or should I keep my 4100. All I do is game.

I got a high leakage chip sad-smiley-002.gif, I need ~1,56 for 4,8 but the temp is over the roof, checkout the pic.

What about my cooling some might ask, well it´s a Heatkiller Rev.3 Copper with a Thermochill PA120.3 and six Scythe 120mm Slip Stream 1600rpm @ ~1000rpm in pushpull.

363

I have to turn those fan up to max and see if the temp gets better, I doubt it though
