Asus 680i, P5N32-E Sli Results.

[vincey2kr1]

friend is having serious problems with this board. No boot sometimes and if it does run after 30mins or so he gets blue screen errors, suspecting its the ram that hes using Corsair xms2(6400) 4-4-4-12 2.1v. Epp and Sli certified What memory do you guys recommend? Hes changed out 2 power supplies 650 watt Antec true power, BFG 650watt is 650 enough for a e6600, bfg 8800 GTX? Also changed out the cpu. Running the latest bios, no beta's. Hes changed out the motherboard for a Commando and getting a no boot screen.

Sorry my mistake see now you did try to fix it with updating the bios. Has he gone up to 1002 bios?? Does he have the sli memory enabled or not?? Maybe try to disable that. Else run memtest and see if it finds any errors with the ram.

I was playing around with my P5N32-E and 4300 and came across some interesting observations,

Ok now i set 1.3V in BIOS for Vcore.Booted into windows,checked Asus probe and i see 1.3V,interesting but nothing great,alright,maybe Asus fixed Vdroop in latest BIOS,who cares

Just to test stability @ 2.4GHz, i ran orthos and left it there.while killing some time on the PC doing nothing,i found something interesting, with full load Asus probe showed Vcore = 1.28V



I was like WTF ! This is a Asus Board and it must have massive Vdroop :P I monitored it for a good 15-20 mins and it didnt budge a little

Does this mean that with newer board revision and latest BIOS,Asus has solved the Vdroop issue or am i just jumping to conclusion too early



I am still on stock cooler so not going beyond 3G ,as Indian summers have just started and the temps are already hitting 40C

Settings -
Vcore in BIOS - 1.4V
Vcore in Windows - 1.39V
Vcore with Orthos Running - 1.38V

So Vdroop is still 0.02V Wooot !!!
here is a Suicide or quick shot though 3.4GHz

Temps were scary @ 3.4 so rolled back immediately.

Oh and btw,the stepping is Q641A373

Nothing more till i slap on my WC kit on after a few days.

I need advice to go higher than 1800 (450) FSB and over 3.6 GHz.

My problem with CPU is that to go from 3.5 GHz to 3.55 GHz it took me from 1.60 to 1.6250 volts. I'm running water-cooling with Apogee GT block. Water temp is 30.5 idle and goes up to 35.5 while running orthos stress CPU with priority 6. I'm afraid to burn up chip. I really want it to last at least 12 months.

The probmel with the board is that I can't do 500 FSB no matter what I try. at 450 FSB exactly it freezes during post after displaying CPU speed. I have to clear CMOS to reset it. I can do 1900 FSB (475), but within the first few minutes of memtest I get errors, and Vista won't even boot. The multi-boot program has internal CRC error-checking and tells me the files are corrupted. Once I back off the FSB it loads no problem.

I'm using the Thermaltake Extreme Spirit II for northbridge and southbridge and Thermalright heatpipe MOSFET coolers in place of the stock cooling.

I noticed Kunnak put high SB voltage in his very first posts in this thread. I'm gonna try playing with SB voltage. I'm sure I might be able to squeeze maybe 20 extra MHz out of both the CPU and FSB, but I doubt I could do much more without TEC/phase.

I'm not going to start overclocking the RAM untill the CPU/FSB are sorted out. Right now at 5-5-5-12-1T @ 800 MHz the RAM is at stock settings for daily use. (I use 5-5-5-18-2T when overclocking.)

ANY input at all would be appreciated.

Here's what I set in the BIOS:

BIOS version - 1103
1.6250 Vcore
1.9750 RAM
1.45 1.2V HTT
1.45 Northbridge
1.60 Southbridge
1.55 - CPU VTT
AUTO - RAM controller
AUTO - Channel 1
AUTO - Channel 2

Spread spectrum - all OFF
Legacy USB - OFF
CPU themral control - OFF
Limit CPUID MaxVal- OFF
Enhanced C1E - OFF
Execute Disable - ON
Speedstep - OFF
Virtualization - ON
LDT - 5x

in the screenshot I was running RAM (DDR-800) with timings of 5-5-5-18-22-2T but now I'm running 5-5-5-12-1T with 100% stability (also ram memtest86+ for 4 hours).

Sorry forgot this:

Setup: C2D e6600 FPO/BATCH L636A786 3.55 GHz (8x444) (12+ hours orthos stable) / Asus P5N32-E SLI / Corsair Twin2x 2048-6400 (5-5-5-12-22-1T) / SLIed eVGA 7900 GT KO Superclocked / Enermax Galaxy 1000 W PSU / Corsair H2O 220 Apex Ultra / Danger Den Koosah (x2)

I don't get it , you are afraid of risking ya CPU but either way you are pumping 1.65 volts through it to get 3.6Ghz.. I really want to know what coretemps you are getting at full load... If you ahve already 66°C on the CPU then yoru coretemps must be over 70°c man ,and that's not good !!!

1.6250 Vcore --> Alter Htt and NB voltages and try to lower this man
1.9750 RAM
1.45 1.2V HTT --> try eg 1.5
1.45 Northbridge --> try 1.55
1.60 Southbridge
1.55 - CPU VTT

Also why don't you use 9 X 400 with ram in sync... seems to me easier to do ... and for me is faster... (but opinions vary on that)

If I would want to keep my CPU for at least a year I would push max 1.55 volts or so through no matter what temps it reached, with your settings 400FSB should be easy to do...

It's weird with my 744G I couldn't do 3600mhz not even at 1.6 volts like you, then I lapped it ( wanted to try it), temps dropped 8°C under load and now 3600mhz is possible with less volts) I reach 3600mhz now with 1.49 real volts under load, coretemps stay at 56°C after 12 hours of Orthos with my thermalright Ultra 120...

And just as a note that Orthos doesn't seem it ran 12 hours mate lol

[Mr.Sinister]

Anyone got 4GB (4 x 1GB) working on this board? So far i've tried 4 x 1GB Ballistix 6400 and 4 x 1GB of Tracer 8500. No luck so far. Tried lots of different timings, voltages etc. Best was Orthos stable for about 1 hour 20 mins then error.

[alexanderhuzar]

Try playing with the memory controller voltages? Did you try stock settings for everything?

DDR3 modules are supposed to draw 5 watts per module...that's a lot of current going thru the northbridge. DDR 2 isn't that far off DDR 3...maybe that could be it...

I haven't yet encountered a motherboard yet that liked having 4 RAM modules in it.

Dude!!! I so did... Why u say I didn't? Now I just ran 10.5 hours of orthos at 3.6 GHz with the settings you told me to do. I'll post screenshot when I overclock a little more...

Temps ate still over 60 celcius. I'll scrape off some of the Arctic Silver and re-attatch the waterblock. I also have 2 7900 GTs on the same water loop (after the CPU and before the rad).
