elite22 please tell me more about the MCH/DRAM reference. I was looking at your
templates and i understand all of your settings. I am stuck trying to increase my
fsb. I have messed with every setting on this thing except the mch/dram reference
I am assuming that you would just do it the same as all the other mch settings
ie... set it up to where memtest just starts to fail, and then start experimenting
with the mch/dram reference until it gets better or worse. I have never even
touched that setting. Does it have a dramatic effect (like the mch ref does) ?
Can you give me any hints?
Very nice cloking you do there. I like it. Impressive.
I want some stable high fsb action here. I seem to be stuck at about 515.

its is basic off the dram voltage & mch, u should increase it for higher dram voltage. i did not see much change, but it should be scaled up like all the ref. voltage as there are not (0.67x, 0.63x, etc.) like on some motherboards they need to be increase with the cpu term and dram voltage they will also scale up if u use( + , - ) in the bios when increasing cpu term, and dram voltages, when cpu term increase this way both the cpu ref. and mch ref. voltages increase with it and when dram is increased mch/dram ref. increases
hope that helps
btw:post ur settings so i can see what u r trying

No, i didn't explain it good enough,
The MCH ref and the cpu ref is easy to set {i just use Jor31BR's golden rule}
thanks Jor
it is the mch/dram ref. Mine is always half of the dram voltage and; yes, it "tracks" with the dram voltage setting, except in your templates you changed it a little, its not half. Was that accident or did you change it on purpose? And if so, did it help.

Just some discussion about MCH temps. I think most modern heatpipes should work w/o gravity, reason being is b/c I have a BTX case so the mobo is upside down. You think it may give me stability issues?

I just notice touching the MCH is hot compared to the mosfet

i used 0.53x for the MCH/DRAM ref.,
2.16 * 0.53 = 1.1448 i did round down tho (1.140v)
it seems to help

btw: whats Jor31BR's golden rule?

F6 on my UD3R has similar issues. That's why I went back to F5.

I have a Revision 1.0 board with an E8600 that does it as well, less so since I flashed it to BIOS F7. I feel there are some voltage settings that should cure the issue on the revision 1.1 mobo with the Q9650 as it was stable at that and higher then 3.87GHz on my GA-P35-DQ6 board. This mobo just has so many more settings that I don't understand for voltages etc. At least I hope some voltage settings will help it.

I agree it has something to do with the OC settings, I just hope to find the right ones to cure the problem.

If you are hearing beeps after a reset or shut down try to test each memory module individual too, sometimes a single bad stick of ram causes the problem.

Use same settings as before but now with a single stick, if the issues stop and you can maintain the settings without hearing the beeps or seeing the red bad oc screen after you power on you got a bad stick.

I am 70 passes IBT stable and >12h OCCT Mix stable with F5 so it's not RAM for me. F6 just seems to have trouble remembering and applying the right settings at boot sometimes. It looks as if it tries to boot with too low PL to me.
