FSX doesn't seem to like my new clock

[vgbaron]

You know.. its also possible those sticks just wont REALLY do 1800 under all applications. Mushkin just shows that for clockers and success in stability is based on simple benchmark stress tests for sales... that does not mean the sticks will run 1800 in all applications. FSX is a memory subsystem killer so you may be stuck at 1600 and the numbers we came up with earlier on those sticks

if worse comes to worse, could we get 450x9 with 1600?

possibly I could get some Corsair and sell the Mushkin on ebay

btw, the corsair ram - is that the one that says it's only for 64 bit systems? ABout $400? I'd like to save the $$ if possible but what the heck.

BSOD from trying 1T?

Then you passed 2T but when set BIOS to 1T it BSOD?

No possible

To get 1600 and make use of the 4Ghz ability you have to run 482MHz on different strap because of how the math works. Unfortunately that quad wont do 9x482

Thats the restrictions of a non-QX processor and not having the multiplier

Passed 2t but rather than set it to 1T IN mmeset I tried to reboot but it bsod on shutdown. Never got the 1t in

You can not change CMD with stability in Memset.. it must be done in the BIOS

So is it OK now? back to 2T?

That's what I thought but wasn't sure if there was a workaround. No prob

That's the way I've been doing it but this time I got the BSOD at shutdown. SO should I try 1T anyway?

I usually set in BIOS... try in the BIOS to 1N

If unstable, try lowering 4 GTL settings to -50 and raise FSB TERM to 1.28

If you cant get 1T stable, go back to -40 1.25 FSB TERM and 2T

test 07 PL

[vgbaron]

booted

OCCT testing  -40  1T

[NickN]

Never change CAS (first value) or COMMAND in Memset... only in the BIOS


If you are stable at 1T then test FSX

If its stable too, then lower PL to 7 and set high tREF and retest

you may have to sacrifice 1T or PL & or visa-versa. You will need to see which has the most impact.. with DDR3 1800 I would think PL 7 would be better to run over 1T

If you find instability with 1T and/or 07, try raising vcore to 1.31 NB to 1.55,..

[vgbaron]

OK stable at 1T - will test FSX and then play with numbers as needed

[NickN]

lets hope this gets you where you need to be for 4050MHz

I am going to call it a night but please do post your results and if you still have problems I will check with Asus this week and see if there is anything else I can suggest

AS I said, 1T is not as critical at 1800 as it is at DDR2 speed so go for PL. I know you wont get PL6 at 1800 but 7 should be stable according to the math

[vgbaron]

fsx froze - raising vcore & nb


THANK YOU for your help. I'll play with the numbers and post.

Night!

[NickN]

no problem Vic

use the numbers and the method I mentioned 3 posts above and see where it comes together

you know the DDR3 1600 settings that work for sure now... you may even be able to push FSB up a tad higher than 400 with those. You can go back in the thread a few pages if you need those numbers and as I recall you managed PL6 and 1T with a stable FSX on those.

1T -40 crash FSX
2T -40 crash fsx
2T 1.31  1.55 -40 crash FSX
2T 1.28  1.52 FSBt 1.30 -45 crash fsx
                                  -50 crash FSX

maybe 1800 and FSX don't like each other no matter what.  :(

Think I'll watch tv for an hour and unwind the brain cells so I can sleep.  I'll play with it again tomorrow afternoon
