i am saying i never trust AUTO for much of anything, and why not try 2T before RMA?

They are below 40 now, not too bad.

I'm getting to the point I think its sorting else, maybe even os related. I want to test this piece by piece. I have memtest and plan to do that but I dont suspect ram at this moment. What is a good way to test video and not memory, or cpu and not video as such? I'd like to know of a few good apps to just test one part at a time and narrow this down.

Thx for the reply!

Additional Comment:

Never mind that results are in and it is in fact my ram. I need some advice on this one...

I have (2) Mushkin Redline pc3-12800 rated at 7-7-7-24 1.65v ( 2x8GB )
I put them in dual mode and ran them at 7-7-7-24. As it turns out memtest filled the page up with red clamming its no ( this was auto clocked ). I ran memtest when I bought it ( few pages back ) and it ran fine.

I now have my old ram back in and test it just to be sure its the ram and not the bridge. All run find for 30 minutes.

So how is mushkin with RMAs? Should I even mention I OC'd to the 7-7-7-24 ( is claims its supported ). Any advice.
Here is my Screenie from the last page.

I dont see any shots of voltage or heat. but I do believe it was talked about and ok at the time. The ram sits on the back side of the fan so its not really possible to cool it any and being in dual mode theyr are neck to neck.

Side note: My old ram will no long run dual? If I put the ram in dual mode I dont get a post. I was able to do this before I bough the new stuff, just a bit weird? Bios settings are all defaults ATM.

If you want tight timings and run more than 800mhz effective, I can tell you that 1.8v would be a good starting point. Put a fan on those sticks or you will fry them period.

I have to run cas 9 at 1000mhz and run 1.88v. You running a much tighter timing than should be for low voltage of 1.65v or less.

If you can't run them mushkin stable at 8-8-8 800mhz 1.65v try just a little more like 1.68v. But I can tell you that after 800mhz, the mem controller is going to want to see the Ram voltage increase beyond factory specs.

How can I cool the ram if the ram is butt up together and butt up to the fan? You can see the MB on post #66 but the fan was on the wrong side in that pic.

Is there a tool that shows ram temps?

one of these spot fans from Antec works wonders.... around $20 or less (http://www.newegg.com/Product/Produc...c%20spot%20fan), and i have mine mounted to a motherboard mounting, using a slightly longer screw.

i believe the Asus suite for the sabertooth series has a sensor near the ram slots, but nothing can actually read the stick temps since there is no sensor on the stick. but any airflow is better than none and you can gauge by feeling them your self.
burning hot = bad

yeah , they did get to hot when I tested with my hand but its possible. The fan is neet, thx!

Additional Comment:

Missing something here, I can not seem to figure out. If I run my redlines and let the board decide the speed its something on the order of 8-9-8-24 @ 800.

The chips them selves are
Voltage: 1.65V Speed Spec: PC3-12800 Frequency: 1600MHztCL: 7 tRCD: 7 tRP: 7 tRAS: 24
That is right from the page. So here is the part I dont get, why do I have to "overclock" in the terms of setting the bios to clock that at the right levels to get the ram to run where it should be. Is it more of a matter of making the NB aware of my RAM? Sort of like, Hey NB I'm going to run these timings deal with it.

Also why does the mushkin page say
Type: DDR3 Voltage: 1.65V Speed Spec: PC3-12800 Frequency: 1600MHz 7-7-7-24
When I need to run it at 1.8v in order to make it stable?

Because the 7-7-7 spec is a XMP profile not the JEDEC standard.
Your rig on auto only reads the JEDEC standards, that's why it's imperative that you set the timings and voltage manually....every single time.

ok I'm back up to speed with my new memory fan. Going to run the ram at 1333 this time around as I read there is not much of a gain going to 1600 with amd. MY cpu temps are below 40 at 4.0 now. I may mess with the clock a bit more but I'll be reaching my heat ceiling soon.

I found this a bit interesting

a 2 gigahertz increase... wow.
