Phenom II steppings and max OC 550-940 - Page 114

post #1131 of 2829
I could boot with a 18x mult with my bus at 200. how ever, anyload caused BSOD and this was with my mem down. I'm no running 200fsb mult at 17.5. Fully stable with HT/NB at 2600 and mem back up to 1067/5-5-5-15-2T

I'm gonna list my mem today and go for a 2x2gb mushkin kit. everyone seems to have good luck with those sticks. OR the patriot viper sticks i see alot of those around

Well my mobo seems to be permalinked to the ref clock. i Cannot seem to set the freq on the ram And wouldnt setting it to 800Hz hurt my performance?

@Warfox:
In the BIOS go to: "advanced-> jumperfree conf. -> DRAM timing conf.
Here you can set the DRAM speed (select manual) and the timings.

Hmm, well it gives me the option of varying speeds... 621,833,1060,1137 for example... but doesn't let me key it in... and ihave notices that this is directly related to the ref clock... i upped my NB clock tho...still stable i'll post my over clock and 3dmark score

Warfox, when you set the "Memory Clock Mode" to Manual it should give you these options, 400Mhz, 533Mhz, 667Mhz, 800Mhz and 1067Mhz. Do you have the clock mode on Limit? That might be causing the problem.

Good luck

@ thlnk3r - Yes, i have it on manual, however, i see the options 400,533,667,800,1067 when i have my Ref. clock at stock (200). As soon as i increase the Ref clock, the freq i see in that tab increase as well.

-Revision RB-C2
-3900MHZ, 200x19.5
-vcore - 1.525v
-HTT link speed = 1800mhz and voltage = 1.25
-Foxconn Destroyer
-motherboard BIOS revision = P14
-Air (T.R.U.E.)

I haven't played around a whole lot yet.....But getting this was so easy...And yes it is OCCT Stable

I am going to lap the 940 tonight (T.R.U.E I lapped awhile ago)

<--- in love with Destroyer

Warfox, very nicely done +1

Have you tried a tRC of 17? Typically the sum of tRP and tRAS should equal tRC (AFAIK). You may want to try also lowering your HT speed so that it is closer to the factory 1800Mhz. Stability issues may occur with a higher HT speed.

Good luck

@warfox...

the CPU-NB frequency, HT-Link frequency, and the RAM frequency are all directly related to the Reference Clock. if you change the Ref Clock from the default of 200MHz, then the BIOS - being as smart as it is - will tell you what the effective frequency of each setting is without having to do math. you can't key anything in, it's just like selecting a CPU or NB or HT multiplier.

so setting the Ref Clock at 200Mhz will give you these effective frequencies for the RAM... 400MHz is 400MHz, 533MHz is 533MHz, 667MHz is 667MHz, 800MHz is 800MHz, 1066MHz is 1066MHz.

now, setting the ref clock to 250MHz will give you these... 500MHz is the 400MHz setting, 667MHz is the 533MHz setting, 833 is the 667MHz setting, 1000MHz is the 800Mhz setting, and 1333MHz is the 1066Mhz setting.

so if you have PC2-8500 ram - 1066MHz - then you need to set your ram multiplier to whatever the effective frequency is that won't go over 1066MHz... unless you want to overclock your ram. get it?

Those are overclocked timings. If you drop your northbridge freq. you can get the 1066 back.
