FSX doesn't seem to like my new clock

[NickN]

Lets back up

I just checked the mushkin site for those settings and he is using a Q9650 proc byt what does not make sense to me is the FSB Termination Voltage. I know he is compensating with that setting but it still seems very low.

Dont change anything yet...

First, we know the sticks are not 1T rated so lets leave them on 2T

We do not know what the PL is for those sticks stable either so lets remove the Windows Memset boot and in the BIOS set common performance level to AUTO or DISABLED

Lets DISABLE AI Clock Twister completely

Vcore to 1.28v should be stable where you had it.

OK, if the voltage on the memory sticks is OK by Mushkin to run 1.95v, set the memory voltage to 1.95v.

Go ahead and set everything back up according to the Mushkin list other than 2N, CPL DISABLED or AUTO and AI Clk Twstr DISABLED

Check Memset on Windows boot and see where PL sits. Run your tests/flights.. if still unstable, set FSB TERM VOLT to AUTO and retest

Let me know what you come up with


Please understand I have never used Mushkin memory for DDR3 and the key here is the memory and NB with the DRAM CHA stability to the CPU. I use Corsair memory for DDR3 becasue the Samsung chips are pretty much plug and go with very little tweaking and this is why, what you are seeing now. OCZ memory tends to show the same fine tuning problems with 2x2GB DDR3.

So lets back up and start with what I posted. If it is still unstable then we will go back to the very basics and start over.. if it IS stable then use Memset in Windows to set PL to 7 and tRFC to highest T and retest. If still stable then set COMMAND to 1N and retest

rgr - only Ai twister has no disabled option - auto then lightest thru strongest.

I'll set it at lightest first and the rest as you specified.

understand about the memory - if it becomes an insurmountable issue, then we;ve learned something and I'll get some different sticks.

[NickN]

Thos sticks are DDR3 1600 2T @ 1.90-1.95v, not 1800

So if you cant get stable then we go back to the basics and start over using 1600 as the base

let me know what happens

I could not remember if twister allowed disable.. lightest is fine

Nick, Can you tell me what the max PLL should be?

[vgbaron]

PL=6 freeze < 1 minute
FSB Auto freeze < 2min

realized I stil had the 178.24 driver installed - went back to known item 174.74

freeze in 10 minutes

Nick, Can you tell me what the max PLL should be?  Is it something like VTT where it wikll KILL the cpu above a certain value?  I have it on the lowest setting in BIOS and HW monitor reads 1.58v.  Should that be AUTO even if it raises PLL to 1.6-1.7v?

Jim

45nm processor max is 1.30v FSB Termination (AKA VTT)

[NickN]

PL=6 freeze < 1 minute
FSB Auto freeze < 2min

realized I stil had the 178.24 driver installed - went back to known item 174.74

freeze in 10 minutes

What does it read in Memset without setting it in the BIOS and disabling Memset boot?

[vgbaron]

yes memset says it's 6 with it set to auto in BIOS

[NickN]

yes memset says it's 6 with it set to auto in BIOS

OK.. so its calc'ing that on its own

Raise/change it back to 07 in the BIOS (verify in memset), make sure memory voltage to 1.95v and set FSB Termination to 1.20v

retest

If fails, raise it to 8 and retest

If it still fails we go back to the basics and the 1600 clock and start over

[vgbaron]

rgr

[vgbaron]

no joy at 7 and 8 FSB 1.20

[NickN]

OK so let me get this strait

You passed OCCT with the Mushkin settings and 40 minutes of FSX running the same settings except 2T, FSB Termination was set to 1.10v and the memory voltage was set to 1.90?

Because thats all that has changed here: FSB Term and memory voltage.. everything else is the same, correct?

[vgbaron]

the 40 minutes came after I raised vcore to 1.31250 and NB to 1.5244 all else same except 2T. However when I raised vcore again to 1.31875 system rebooted during OCCT. These last tests were back at original settings except as you suggested

[NickN]

OK, I figured NB needed to be 1.52 as most board need at least that

As for Vcore, that problematical and may need to be between 1.28-1.32v

Are you in the white or blue slots with the memory?

[vgbaron]

in the white as suggested by Mushkin. Also, the diagram in the manual indicates white for two sticks alone
