Crysis still sticks a bit. I need a new DVI big monitor.

Edit: maybe a stupid question but how do I assure that my RAM is not running too fast when I am increasing the FSB?

RAM Speed Formula---FSBx MM (memory multiplyer)= RAM Speed
460x2.4=1104

@ Bradley--a Samsung 22" or 24" is a good choice

Dennyb, what's xx?

Wow - first of all - thanks for the enormous amount of help I am getting here form DennyB

However, this can be really frustrating if it won't work

my settings as following --> end up in a blue screen when booting...

I replied inside the quote and it won't let me post unless I type in a couple characters--no meaning

First try "A" latch --2.50 MM----456x2.50=1140. Sometimes selecting a different strap will cure what ails you.
Still no love? then try raising v-core to about 1.36 or so and bump Term to 1.320.
Still no go bump MCH Core to1.32

Oh well, still no luck. That is weird...only auto works for 4.1 GHz. Oh..I see a variable now that helps to increase stability...if I increase the RAM voltage to 2.19V then it is stable at 4.2GHz...but I am still back at 1.42 CPU Vcore and 2.2V RAM...that does not sound good to me...

Hi everyone - I've got a seemingly odd problem here, but if anyone can help it should be one of you...

I had this same CPU (q9550), Video card (4870), and RAM (g.skill 1066 2x2GB)on an EP45-DS3L that I was able to overclock to a FSB of 410 MHz no problem. The only reason I didn't go higher was the northbridge heatsink was getting VERY,VERY hot. So I picked up the UD3P to solve that problem but can't get it anywhere near 400 MHz...

The optimized defaults can run Prime95-Blend or memtest86 overnight no problem (FSB 333). But with the BIOS settings below memtest runs overnight, Prime95-SmallFFT runs 5+ hours, large FFT or Blend fails in 1-2 min, always on core 1, then core 2. The windows version of memtest finds an error every couple of seconds. Core temps never get above 55, and MCH/ram is barely warm so I doubt that is the problem.

This seems to be some sort of MCH or RAM issue, right? I've tried taking out one ram stick, moving them to slots 1 and 3 (are in 2 and 4 now), and using some old DDR2 800 PNY 2x2GB, with essentially the same results...
Dropping FSB dosn't solve the problem until its <340 or so. Messing with Vcore,MCH core, etc doesn't have a noticable effect on the number of Prime95 errors.

Any idea what's going on?

As a side issue, is there a way to find out what the AUTO voltages are actually set at? EasyTune doesn't like Win7-64 bit and everest won't get a signed driver for it.

Term is too low... General rule of thumb is .3/.4 lower than your vcore... so try 1.30 term.

NoGuru · 2 Weeks Ago

Crap I wish I had some time to work with some of the new guy's, but just got home and heading out for dinner and drinks. So I'll try and get back on tonight or tomorrow.
Just listen carefully to what these guy's say and all should be good.

Egads, Guru is trusting me in this thread without supervision?
