Sig shows the system just got it up and running andthought I'd seek advice and suggestions for fine tuning.

current running prime blend
cpu: 11 x 260FSB = 2860MHz core 1.5 V * 110% = 1.65V speed fan shows 1.61V
mem 5/6 divider 204MHz 3.2V. I was gettin about ~1 error/pass in memtest so needs some minor tweaking
temps: case closed: 63C cpu 51C pwm 54 C chipset case open: 58C 44C 48C
I guess I need a intake port over MB

update BSOD 30 min into prime blend need to change something :(
those temps seem high what you all think? do I need to ease back on voltages?

ok dropped core voltage to 1.5 * 104% dropped FSB to 255 raised mem divider to 9/10 will try prime again.
 
Hey, we have a similar setup, just built and tested mine over the last week. About tore my hair out, lol I simply can not pass Prime95 nor OCCT nor the memory write test on PCMark. Without getting into a ton of details I personally think I have a bum CPU, but I have been runnning stable besides that. All 3dmarks are great, Aqua, SuperPI, etc. I found the sweetspot to be (like others with the 3700+) to be 2750...I'm at 10x275. Anything higher than 2750 at any multi crashes eventually. I did rule out memory, my sticks can go at least DDR600, had them at 9x300 yesterday. They are running 275 right now.

Anyway, yes that CPU temp is really high...what heatsink do you have? I'm idling right now at 28c using 1.55v. My PWM is 34c and the NF4 chipset is 41c...the chipset is made to take really high temps though so don't worry too much about that. If you don't have a decent heatsink for the cpu I'd reccommend mine or the copper version of it, works wonderfully.

For more stability you could up the LDT voltage to 1.3 and chipset to 1.7, and my memory is at 2.7. And if you haven't done so yet check out the official support forums for DFI at http://dfi-street.com They are really active with the board owners and have tons of info there.
 
thx nice to have feedback from someone with same setup. I forgot to put HSF in sig it been amended.

I've been running prime @ 1.52V cpu core for about 2 hours temps have settled in at 51 cpu 43 pwm 48 chipset out air temp is about 80F (26C). I'll probably need to cut opening for 2 120mm fans over my MB to get those temps with case closed. My idle temps sound 3 or 4 C higher than yours, case mods may fix that.

I avoided tweaking chipset voltage as it already seemed to run so hot but may nudge it a little. The memory may be able to take more voltage but 3.25 seems pretty high already and I usually back off a bit of max on setting so I have some headroom for unexpected events.
 
update:

wel it seems with my current voltages of 3.2 on mem and 1.5 on cpu my system will do 11 x 255 with a 9/10 FSB divider. If I move cpu to 11 x 260 I get prime warning/errors and if I move the divider to 1/1 I get memory errors. I seem to be able to get the memory to higher speeds but only by lowering fsb to 245 and raising divider to 1/1
 
kinda sucks that your having trouble with the memory controler, if it wernt for that those chips prob could go a lot higher

So you think it's the memory controller on the CPU and not the memory?
 
i have had problems myself with my dfi and using ram dividers. it really bothers me, thus i leave my ram a ways below the max and just use the top divider

however, you should be able to do better than 245mhz with 3.2v.. can you give me a list of what you have every memory setting set to in the bios? :p

GRRR something is screwed up back to same BSOD. Repair didn't work had to reinstall OS from scratch and had to go into safe mode again to finish the install. I'm not going to reinstall my OS every 3 or 4 days. I don't think this is a OC issue as prime and memtest run fine.
 
Do not worry about it. @ 3.2Ghz I am not stable in 3DMark, but who cares? Everything ese I run is perfect. As long as all of my games and tunes run/play fine...I am good. :D

I am so jealous. I can't wait to see what my 4000+ will do. I only have it on air cooling atm, so no 3.2GHz for me... but I'm hoping for high 2s. I start the OC process tonight. :)

Someday I'll give in to the itch to drop major bucks on phase change... for now, I'm going to relish in the upgrade from my old 1Ghz Athlon :cool:

ok back from the no computer wastelands. Update: seems my w2k OS disk was corrupted switched to XP pro and seem to be ok.

alright, latest test is 270 FSB x 10.5 = 2836 CPU and memory is 9/10 = 473 2-2-2-6.
I had to raise mem voltage to 3.5V to get this stable in memtest. CPU is at 1.5V * 110% = ~1.63V testing in Prime ATM but seems stable. I'm a bit concerned with the temps under load as cpu jumps from about 37C at idle to 55C at 100%.

I can get mem up to ~500 but have to lower CPU to about 2700 to manage it.

3.2GHz turns me GREEN. :)
 
CPU is everything. Max out your CPU and do whatever you need to do to the memory to make it stable. AMD 64s pretty much never max out their memory bandwidth, but CPUs are another story.

55º C does seem pretty high. I'm still running stock voltage @ FSB 220 until my Mushkin Redline comes in, but I never go above 38º C and I'm using a really low RPM fan. You might want to try reseating the XP90, maybe you got an air bubble in there or something. Dropping 15+ degrees off your temps might allow you to bump the FSB a little more, and maybe hit 1:1 on the memory.

Ok tweaked a few things.CPU Voltage is now lowered to 1.5V * 100% (reading 1.47 in speedfan) and I lowered FSB to 268. Reset heatsink. Temps dropped to 45-46 C @ 100%. Ambient temp as measured by probe at front intake fan is ~31 C. Is 15C a reasonable differential ? Running Prime ATM.

Something you suggested helped but not sure which I'm guessing it is lowering the voltage almost .2V on CPU.
 
Update tonight: since I decided keep my mem voltage at 3.2V for the meantime. I'm trying a different route. Taking ryuji thought that it was the mem controller on the CPU and something I read over at bleeding edge I lowered the cpu voltage down to 1.3 but raised the special multiplier to 123% for effective CPU voltage of 1.55-1.57V. This has allowed me to get HTT up to 259 for 2850mHz. Running prime now has been stable about 2 hours so far. The extra voltage/speed Raised CPU temps about 3C - 4C but still about 15C over ambient
 
I think I've played this string out but one last go.

I am currenty running prime at 11x262 @ 1.3Vx123% that should be 2882Mhz @ 1.6V (bios says 1.55V) mem @ 1.5-2-2-8-1T 3.3V 3.3V rail @ 3.5V

was also stable 11x259 @ 1.275Vx123% 2850MHz @ 1.57 mem@ 1.5-2-2-8-1T 3.2V 3.3V rail @ 3.38V

mem is 9/10 no reasonable way to get it 1/1 without switching back to 5V or dropping CPU speed dramatically.

temps are stable at 15-16C above ambient for CPU under full load.

So any opinions on getting more or is it time to call it quits before I trash something:)
