680i SLI is too expensive? Asus as the solution : P5N32-E SLI PLUS

[Carter]

Has anyone had luck with the 805 BIOS?

I just ran a dozen tests and it cannot get anywhere close to what I was running using v801. I tried unlinked, linked, linked $ sync. FSB of 375 up to 451. It would do 3.2 Ghz w/ DDR 800 400 FSB. Anything that bumped the memory much past DDR 800 made it fail to post.

I have an E6750 so I thought the "improvements" in 805 would help. Does anyone know of islands of stability in 805?

I am at FSB 431, DDR 868, 3.447 Ghz using 801 unlinked.

I had to back to 0801 with an e6700 my system was just not stabe that bios rev is a bust.

Hi guys, im new here and pretty new in oc scene.

Runnin e6660, asus p5n32-e sli plus (bios 0801), G.SKILL 2x1GB DDR2-800(PC2 6400) Dual Channel Kit, tuniq tower 120 set on max, antec 900 (three 120mm and one 200mm set on max).

Everything in bios is set to auto/default

Tried these settings so far :

[==-Run 1-==]
300 FSB (1200)
orthos blend mode for 10 mins... no errors.

temp core
idle: core 0 13C , core 1 12C (pretty cold room tho)
stressed: core 0 30C, core 1 28C

Question: Should i choose linked or unlinked?

[==-Run2-==]

using unlinked 1:1 ratio (is that ok?)

orthos blend mode for 10 mins no errors
FSB 333 (1332)
DDR 666

temp core
idle: core 0 15C, core 1 13C
stressed: core 0 35C, core 1 32C

[==-run3-==]
using unlinked 1:1 ratio
orthos blend mode for 10 mins no errors no warnings

FSB 366 (1464) ==> 3.294 Ghz
DDR 732
idle: core 0 15C, core 1 13C
stressed: core 0 ~38 C, core 1 ~36C

Should i let orthos run longer and at what temperature i should stop? 50-60C stressed?
Also should i use linked or unlinked tho?

overall looks nice rite? Knowing that voltage and timming settings set to auto/default and i reached ~3.3 Ghz.
Looks like i can reach 3.6-3.8 with decent voltahe&timing sets/numbers right?

What should i do next? still increase only fsb and ram... or start playin with timming and voltages? if yes what numbers should i put ?

Any advice r welcome... and sorry if i post in wrong thread or wrote somethin lame...

thanks a lot...

Edit:

fsb 380 (1520)
ram 760

orthos : pc restarted after 1-2 mins

idle: 0 core 13C, 1 core 12C
Stressed: was not payin attention ... lol

Another Run ...

375 (1500) ====> 3.375 Ghz
750

idle: 14c, 13c
stressed: last 1-2 mins 44c, 43c.... most of the test mid 30's.

I'm with 0803, 0805 is horrible. Now benching 8x448 (4036MHz) with 1.616v.

[spajdr]

I get this mobo last week and for now im running over 0801 bios, cause with 0805 i cant overclock my Q6600 at all, i read some tips over previous pages, but i cant get my Q6600 to run higher then 3.15Ghz. Weird thing is that i set 3.2Ghz then run prime95 for 3 hours, it was without a error, then i stopped it, watched some movie and after few minutes BSOD IRQL LESS THEN EQUAL i tried to increase voltage on various things, but it didnt help, also 1432 1532 1632 boots PC but hangs at AI logo bios welcome screen, other FSB didnt boot at all, guess its FSB holes.

Should i try 0803 also? i didnt see it at asus page only 0801 then 0805.

[Jultsu]

use a lower multiplier for the quad and try to get the NB and other parts stable first. After that just raise the multi and cpu voltages..

[spajdr]

NB is fine, though SB, its very hot, even if i using fans, i tried yesterday also some lower multiplier, but what FSB? since its kinda annoying to reset cmos all the time, its under second gfx card, so i need to take out battery, thats faster solution but still annoying well i can try to put HR-05 on SB.

[spajdr]

So 7x450 works, but always around 3.2Ghz its end, it locks up randomly in windows then on boot screen after i restart it.

[goatboy]

From what I can remember, others state that there are holes at certain values with this board. Try something a little above or below 450.

[memory]

Does this post support up coming 45nm cpu??

[rootsayen]

Dual Core, yes. No Quad

[Jultsu]

I sold my e6600 and I'm gonna get a q6600 on sunday. Hopefully this board will go over 400fsb, or else I'm gonna have to look for a newer board :/

[TimoneX]

Definately a quirky mobo. Hates VTT w/ my e6400 and almost won't boot with any value over 1.3v here. Odd since it reads 1.32v in the BIOS when it's set to auto. Also I have absolutely no luck with 0801 BIOS and 0805 works far better for me. I had to reset the CMOS so many times while fiddling with voltages to stabilize the board/e6400 at 3.4GHZ that I finally put a momentary switch on the reset jumpers and wired it out the back of the case. My setting right now are:

Vcore - 1.575
Mem - 1.85
1.2 - 1.25
NB - 1.3
SB - 1.65
VTT - 1.2

This has me blending at 3.4GHZ right now when I couldn't even get a post at higher NB & VTT settings. Strange board indeed.

I have an E6750 and OCZ Titanium XTC DDR2 PC2-6400 800MHz EPP-ready (OCZ2T8002GK).

When I first got the board it came delivered with the 805 bios pre-installed. I cranked up the FSB to 1600 and rest on Auto, it ran like a charm, but then after two days it crashed and then nothing seemed to work. I went back to the 801 BIOS because people here and elsewhere said it was better and nothing really worked then either. I tried alot of settings people had posted but none of them worked. So, after a while I got pissed and decided to go back to basics, cranked up the vcore to 1.5 and set all the other voltages to the lowest settable value.

I had read about the FSB holes etc and figured that 1600 might be a , so I went with 1650 and set the memories to 825 to get a 1:1 ratio. The system started all fine, but I got errors in blended orthos after a while. So, I went back to BIOS, increased all voltages (almost) with one step, and gave some more juice to my RAM. They are OCZ so they are rated to 2.3, they need lots of power. After that, booted up, and Orthos was blending all day long no problems, so I reduced v.core to 1.45 and it still run fine as a bird.

All I have to do now is find the lowest possible vcore and tight up the RAM timings a little bit. These RAM sticks are rated to 4 4 4 12 1t in EPP (sli-ready) mode, but I cant get them to run on 1t, which isnt a big surprise, very few people seem to actually manage that so I am fine with 2t (I think, we will see! hah!)

I am running all my fans on 5v and since I have an ancient case, they are all 80mm, so my airflow sucks donkeyballs, thus, I decided that eventhough things are very cool (sub 40c idle, 60~load), 3.3 seems quite fine for everyday use.

[TimoneX]

Sounds about right. 1600 has never worked for me regardless of CPU (2160/e6400) or voltage. 1640-1800 is where it's at for me. Seems like the board has alot of "holes" ...or more accurately there are small islands of useful FSB settings that work in a sea of instability.

So which BIOS did you end up with Ernesto?

Sounds like you should go shopping for a case that doesn't suck ummm...donkeyballs. Might I suggest the CM 690 if you're looking for something cheap with great airflow? I nabbed one for $30 after rebate and it's a heck of a value mid tower.

[Leeghoofd]

[G]Ernesto you mean you set 825mhz then to keep the 1:1 ratio instead of 850 in ya template ( which should correspond to 1700FSB aka 425mhz )

I think for 1T you would need to increase NB voltage... but like you said it' sbetter to have stability over that 3&#37; gain

[[G]Ernesto]

Oh yeah, you are right, 825mhz on the memory and I stayed with 801 after flashing.

Although I did just get a BSOD after 5 hours of gaming, so turned up the v.core two notches to see if it helps. core temp is never above 50 atm after I reduced from 1.5 to 1.45, now up to 1.4625. Eventhough Orthos is stable, not always are the games it seems hehe.

I have been scouting for a new chassi, but then again, no matter what chassi the noise will be too annoying to sleep with (computer right next to bed) and gaining a few degrees in cooling might not be worth it, we will see. I have been looking at the antec p182 for a while, it looks pretty solid, but its a bit costly. Anyways, not to derails this thread since it's about the motherboard but my conclusion so far is that the board is quite good, a to overclock, but performs rather well once you got things stable.

[goatboy]

That's good news [G]Ernesto.

[Carter]

I cant seem to get my FSB stable on anything past 1500.

I can boot up to 1680 right now with current settings but it fails blend immediately.

CPU multi 7

Vcore 1.45
VDIMM auto
1.2ht 1.5
NB 1.5
SB 1.55
CPU VTT 1.3

memory is running 1:2 ratio to try and figure out FSB limitations at 4-4-4-12 timings. IE 1600 FSB = 400 ram frequency.

My voltage are extremely high already and I know I cant move VTT or SB any higher with system crash and bios resetting. I have had my processor stable at 3.5ghz with a 10X multi on 1400 FSB with 1.45 vcore so I know my vcore is fine.

Do I dare to push my NB or 1.2HT and higher?

My temps are fine and its winter here so room ambient is 20C and I have a fluke temp probe on my NB which has an after market TT cooler and it neve exceeds 38C. SB and Ram are warm tot he touch but much cooler when probed than the NB.

Any suggestion on what I might need for stability or am I stuck at 1500 fsb?

thanks Carter

[Leeghoofd]

If you run eg 425 FSB with a 9 ratio you will get 3.8ghz but you will need to push CPU VTT prolly... but why don't you use ya 10 multi and just try 360mhz... is that a FSB hole on ya mobo ?

The limit for my CPU is below 3.6 I cant get it to runt dual prime95 at 3.6 for any amount of time with a decent vcore and low enough temps. I can get however 8 hour stability at 3.5 with 1400 FSB and a 10X multi. This however puts my ram at 700 in 1:1 and this board does not seem to like running at 5:4 or 3:2 for me to get my ram timings up.

I did find another post that memory sub timings gave people issues on blend testing so I will look into tweaking those tonight.

Memory sub timing post:
http://www.hardforum.com/showpost.ph...3&postcount=91

my goal is a 440 FSB with 8X multi and this gives me 3.52 cpu, 1760 FSB and 880 memory which I believe my crucial ballistix will do at 4-4-4-12-2T timings.

its a stretch goal but its been hit with this board before.

I actually I had heat problems - Not on the CPU or the GFX but on the motherboard itself. I both blend and small FFT for 8+ hours with no problems with all fans on lowest, but when I play games, I lock up after a while due to the added heat from the GFX card (I have an overclocked 8800GT with Zalman cu700). So, the lockups I had earlier and thought it was due to low voltage was wrong. I went into BIOS, lowered my CPU vcore from 1.45 to 1.325 (!) and lowered RAM volts from 2 to 1.9, also took down the SB from 1.55 to 1.5. This lowered my CPU down to 31c idle (Zalman 9700). With front exhaust fans on 12v the motherboard temp sensor goes from 41 to 27 in Everest, and this keeps my computer stable in all games, although just to be sure, I crank up the CPU fan to max as well, I play with headphones.

So, my conclusion has been as follows: For me the voltages has never been a problem at this low FSB (1650) but rather the heat on NB or SB (I don't know which, I Assume NB?) so with just some added cooling and overall colder components, things are running like a charm.

I can only compare with my own little knowledge about this, what I have experienced so far, but to me, at least on my rig, higher voltages was bad, keep them at a minimum and increase cooling on the motherboard, that kept things very stable without any need of increased voltages anywhere (almost).

I also have my computer right next to a small vent in my window, which is next to a radiator, so when I open the little vent, the cold air stirs down net to the radiator and ends up right next to my side intake of the computer, which lowers the overall room temperature with about 1, but the case temp with 5+, which is brilliant. My only worry at the moment would be when the summer hits and my southside window and room turns to 30+ ambient, that will be a biiiattcchhe =).

Btw, if I raise my 1.2v HT with more than 0.05 I crash and burn like a mother, I guess that would be because Leeghoofd is using an E6600? No idea, but with my mobo and E6750, I cant even though the 1.2v HT or things go haywire.

[spajdr]

so i exchanged that crappy heatpipe cooling and replaced it with thermalright stuff and voila

[Radical_53]

I'm pretty happy too with the Thermalright stuff. Put it on the mosfets and both parts of the chipset, works nicely even in passive mode.

It even likes my new ReaperX RAM

[spajdr]

guys is there some vdrop pencil mod? cause vdrop is pretty big on 3.6Ghz quadcore, i seen some for P5B Deluxe mobo, but is there some for this mobo? thank you

[Radical_53]

Yes, the same mod as on the Striker board.
