View Full Version : Need help with my new 3.0C
I just got my 3.0C 30 Cap SL6WK in today and I can't get past 235 1:1 or 5:4 with this thing stable. So basically it's the same song and dance that I was experiencing with my 2.8C. I'm running Corsair PC3200XLPro sticks and other people have been having great OC/ing results with this ram, so I don't think that is the problem. But something is making me hit a wall at 235FSB even with 3-4-4-8. Any ideas as to what could be causing this?

Are your GAT settings set to A-A-A-D-D.
Are your GAT settings set to A-A-A-D-D.
is that stock setting? Actually not sure what GAT is.

go in 5:4 leave the loose timmings and give the memory some more voltage also give your cpu some more voltage....what are your temps??
I have the same stepping 3.0C...whats your vcore at the moment. at 235mhz fsb..I had to kick up the vcore a little to get it to work....most people i've read that have the SL6WK stepping have been able to hit 250fsb with low voltage lately..mine is at 1.55v..but like people say all chips arent the same...
have you tried memtest to test your memory?
Okay, I've tried pretty much everything. Tried all vcores up to 1.70. I've had my mem voltage set to 2.85 since I installed the mem. I've tried 3-4-4-8 from the beginning to hit 250 with no avail. And whether or not I run 1:1 5:4 3:2 doesn't matter, I still hit the 235 wall all the same. Just like with my 2.8C. I'm going crazy because of this. It's rediculous, I've got a very decent watercooled system with nice RAM. There is no reason I shouldn't be able to hit 250FSB. I havn't even heard of a 3.0C not hitting 250FSB with good RAM. And my 3.0's pack date is 3/08/2004, which is pretty recent as far as the 3.0's go. There has to be something else. I've even disabled Fastwrites on my vid card...I don't see any fast write setting in the bios. And Asus doesn't have GAT. Abit has GAT. Is it possible that it's my PSU?? I'm running an Antec 430 trupower. And my temps seem to fluctuate quite a bit, between 30C-42C/roughly peeking at about 105F.

well, i just got a SL6WU 30cap and its pretty much on par with you. I hit 245 max FSB and that was with a ton of vcore and wasnt so stable...240 was rock solid but it still needed more vcore then i had hoped for. Its just the luck of the draw man. I just wish i trays of like 30 OEM cpu's to play with just to find the best one.
3.0C did 244FSB stable at 1.65V but 245 would be instant fail for prime. I tried everything with mine as well, 1.7, 1.75V...250 was a no-go. I sold mine, had high hopes for it too. good luck with it, but seems 244FSB is limit for many.
Mine was SL6WF i belive, packdate March 21/2004 - was a 12 cap. I think its the limit of 3.0C, you got a dud like I did.
Myhre...is there any other ram you can try with your system..just curious to see what your results would be? ...you do have some good corsair ram, but you could try to eliminate that as your limiting factor...that 3.0c should be able to do 250 fsb...
aslo my pack date was 3/5/04..so we pretty close in manufacturing time..

aslo my pack date was 3/5/04..so we pretty close in manufacturing time..i was thinking the same thing.didnt you try the 3.0c with differant ram tho?
also post your psu rails. 3.3,5,12v
post temps idle and load.
My voltage rails from my Probe or from my PSU spec chart? I'll give you the probe voltages first.
12V=11.97-12.038
5V=4.999-5.026
3.3V=3.28-3.296
Vcore 1.55Bios atm=1.584-1.6
Well the only other Ram I have handy is some POS PNY mem from compusa that I have stuffed in a box around here somewhere. I've run memtest on my mem for about an hour and had no errors. Accidently hit a button before it finished though. I just don't understand what the deal is with my comp. I really don't understand what could be dragging me down. I really don't think it's the 3.0 I kind of wish I had some pc3700 or pc4000 to throw at it to find out.
Idle temps 86F Load temps 101F. My 2.8 never got above 96, even while stress testing and this proc gets above 100F without even trying. Now if I'm trying to work the hell out of the proc i.e. running 2 or 3 vid games in the background + cpu burn in then I can get it up to about 115F

psu looks fine.
memtest i usually only use one pass its rather thourogh,but is a good mem burn in.1 pass takes about 10mins tho.
you should try the other ram and use 5:4 dividers if possible just to see if the mobo is having issues with the corsair.
pls use celcius temps when ever possible,i can decifer those enough tho.
does the asus mobo have a thing were you can lock the agp/pci bus down to 66/33? is that set?
if the other ram does the same as the corsair its not that.
also whats going on is it rebooting inside windows? errors? lockups?
also mabey check the mosfets around the cpu socket with your fingers and see if they burn you. i think you may not have enough airflow in that area and the pmw circuit maybe is overheating.so this while its at load and heated up.
Yes I have the agp locked down in bios. And I have actually gotten into windows with 250FSB and then everything errors and it restarts by cutting all power through the mainboard and rejuicing everything(I'm able to hear everything on the system click, mainly the hdd's) I'll find the ram real quick and throw it in and see if I have any luck. I'm gonna cry if my $370 set of RAM is limiting my board.

more questions.
im thinking your useing raid0 on the ichr south bridge for your OS? is there any way you can boot off the ata drive you have?
also is the bios the latest?

really check those mosfets around the cpu socket and by the big caps at load. this will kill your oc faster than anything.
but try the other ram also. its just the pwm circuit stands out to me atm with no cpu fan blowing.
i think that new ram is fine man.
Well it's not the RAM, the generic stuff does pretty much the same thing. Half boots into windows and then shuts everything down. I'll be checking the mosfets now.
Edit: Just checked the mosfets. They are decently warm to the touch, but not overly hot. I can hold my finger on them without having to pull it off from heat.

on the mosfets was the cpu at load?

Yes I'm running Raid0/no I don't have a bootable single ide or ata drive.
I had cpu burn in running while I was checking the mosfets. But I only have the proc clocked stock 3.0 200fsb atm
I guess I need to just start considering selling the Proc and buying a new one. I'd throw it on my spare asus P4P800 board just to make sure, but it has lousy air cooling anyway.
Thankyou for all the help guys, I guess I just got another dud. Was really excited when I saw those 30 caps. Guess it was all for naught.
One other thing that is kind of wierd. My load temps even with the proc set at 200fsb gets up around 40C.....I have no idea why this would be, I've never had a stock non overclocked processor get above 35C while being watercooled

ever have issues with sata raid on that mobo and high fsb running? ive heard about before but not sure its that mobo.
yeh the other mobo will confirm the cpu issue. it will work on air cooling long enough that a little high temps wont hurt anything.
pmw circuit sounds ok also.
what about bios did you say its most recent or not?
rather narrowing it down to the cpu sucking oc wise or the sata being not able to handle the buss speed,i think its the issue as it runs synch with the fsb on the ichr south bridge is why i think that may be couseing this,but im unsure.
so testing the cpu in another mobo but whithout the sata will be needed.
good luck man i dont think i can much more tonight but ill be checking back tomorow.

Yeah I'm using 1016 bios. Thankyou for all your help. I'll test out the proc on the other mobo tomorrow. I'll even drag out one of my other antec PSU's. Night.
So my computer booted into windows at 250FSB 1:1 3-4-4-8 1.55vcore 2.85vdimm, for about 2 minutes. I then set it to 250FSB 5:4 2-2-2-5 1.55vcore 2.75vdimm and it let me play in windows for about 6 minutes before clicking off and repowering and rebooting. I then set it to 245 5:4 2-2-2-5 1.55vcore 2.85vdimm. It rebooted after about 10 minutes. I was even able to run superpi. I broke the 40s mark and got 39s. So now I'm down to 240fsb 5:4 2-2-2-5 1.55vcore 2.85vdimm. So why has my system given me temporary stability at 250FSB I ask? The only thing I've done today was ram the comp with 2 PSU's which did let me load into windows, but now that I've switched back to just 1 PSU I've been able to boot into windows for the longest amount of time thus far. What does this mean? Does this mean that my PSU(antec430 Trupower) is having major issues? Or could it still just mean my proc is a gimp and is just trying his little heart out? And what is up with my idle temps goign way down all of a sudden??? Hanging out around 26C at 250FSB. Anyway if you guys have anymore suggestions/advice I'm more than open to it. Thankyou.
Edit: As a side note, I am now running my proc at full load 240FSB 5:4 2-2-2-5 vcore 1.55 vdimm 2.85 and right now my Asus Probe(newest version which I've heard is very accurate) is reporting that my Vcore is between 1.488 and 1.500. That doesn't seem correct to me so what does that mean? Is my 12v line not able to keep up?? Is that my problem after all? And my Full load temp is 36C.

hey do you use a cpu cooling program or ever used one?
like cpucool and a few others some let you change the fsb also.
these things will couse the cooling effect and also make it very unstable at high oc's and also make the psu seem to act funny.
if no to that im thinking gimp cpu.
cpu cooling program? Nope, I don't think so.
Another interesting little fact....I've been watching my Asus probe. Right now I have my vcore set to 1.55 in bios. When my cpu is idle it says it's at 1.6, and when I load my CPU it drops to 1.500!!! Could this be my problem? When the CPU is trying to pull more watts/amps whichever it looks like it's dropping the voltage drastically...well vcore wise 1.5-1.6 is a pretty big gap right??

yeh thats what made me think a cooling program mighta been installed before.does the asus mobo have a cpu disconnect feature in the bios? disable it if so.
id hook up with someone in the asus mobo section and see whats up if the mobo have voltage issues i know ive heard something about that, droop mod i think is needed? i dont know.
or is psu but that sounded ok and if the rails are fluctuating its definatly the mobo.
did you try the cpu in the other mobo?

Good to see that your at 240fsb now...you might want to give that chip more vcore..i have mine set at 1.6v but it undervolts it to 1.55v..after i made that adjustment i was able to run 250fsb stable...
I've got mine set to 1.65 right now, but it droops to 1.55 under load. I'd go above 1.7 but I know it comes back up when not under load, and I don't want to fry the chip. BTW is there a way to check Vcore with a DMM? If so where? I'm using a Fluke 73III and a RS DMM.
If you running asus p4c800 dlx, watch out the vcore 1.625 1.65 1.675 does not exist, yeah you can set it in bios but all of those vcore will equall to 1.6 under load , so if you set it at 1.6 vcore it's better, check with asus probe that under load 1.6 will equal 1.6 and if you set 1.625 and 1.65 will be under 1.6, the 1.675 will work almost as 1.6
Asus board overvolt but that nothing to worry, so if you set to 1.6 vcore the probe will read it somewhere 1.69 idle and 1.6 underload, If you want to check vdimm there is a way but I don't think will help becase this board doesn't have probelms with vdimm fluctuations
Here is whats really wierd. I can set my Vcore in bios and when I set it to 1.60 it's 1.6 at idle and 1.55 under load. So when I set it to 1.65 it's 1.58 idle and 1.52 under load. Why would this be? Is something wrong with my mobo?? Also, with Vcore set to 1.7 it's 1.69 idle and 1.568 under load. I'm baffled.

yep asus has some issues with that board. my friend had one it was POS
got an IC7 on my recommendation and has been very stable and happy with his ocs

Yeah, no kidding. Well right now I'm up to 245FSB. Still falling short of the 250 mark. I'm having to play mind games with this Vcore. I'm actually considering switching mobos. Although I really like the ICH5R Raid and a few other P4C800-E Dlx options. I'm just not sure what to do. Like I said early on, I think this chip has a lot of potential. Do you think I should just look into RMA'ing this board?
You can do droop mod to take care of fluctuations

2. Go with an Abit Mobo
3. Get a new PSU.

is this the first 3.0c? or your second?
i love my ic7 fast as hell and had it over 293fsb so far no issues
that new ocz memory volt adjuster wont work without a vtt mod on the mobo.mem is 2.8v max.
thats the bad sides everything else is great.best mobo ive used since the nf7-s rev2
your psu is fine
im betting the cpu is a decent ocer also.
just get a differant mobo or asking in the asus section what they think can be done to help the mobo without big time mods.

Okay, thankyou for the input. I think I'll try a new mobo before giving up on this proc. Wish I had a friend locally with a proven overclockable mobo that I could stick this proc in. That would save me a lot of time/money/headache. Oh well I'm off to the Asus forums. Btw it's my first 3.0C.
one note before you change mobo or look for one, you asus board support 1.6vcore and this vcore stays almost the same under load, you will need a mobo which will be able to give you 1.6+ underload without going over 1.7vcore
Is your cpu 3.0 with 30caps
yes it is a 3.0 with 30 caps. Oh and also, I forgot and just re-noticed...but under load my vcore will drop all the way down to 1.52 and even lower under REALLY heavy load.

I think your processor is good to at least 250 fsb....It might be your board that might be holding you back...My ic7-g is great, easy board to overclock and rock stable....
I suggest you try out an abit board....

Seeing as how I need another P4 board if I'm going to keep my 2.8C, I might as well try out an Abit board. I'll test it on air first and decide which one I'll use as my main.

dump the asus. i did after two days, lol that POS. Just look at those teenie weenie mosfets half the size of tic tacs!!!. You call those mosfets? Compare it to the IC7 and the asus needs to hide in a corner and cry in shame. i had a 3.0 that can hit 256fsb on my IC7 before i spilled water on it (dont ask). Tried the Asus and i couldnt get past 240fsb cause the vcore drops to like 1.5 or so even though i set it to 1.675 in the bios. I sold it and overnighted an IC7. Got an even better cpu and now im sitting pretty at 260fsb :)
Well, the verdict is in. After installing my new mobo and resetting all my waterblocks. First and foremost, my CPU temps hang around 76F idle and 80F full load now. And they drop right back down to idle temps at idle. Second of all, I HIT 250FSB. In fact, I hit 250 FSB at auto Vcore and auto Vdimm. Although I wasn't fully stable and I dropped out after about 5 minutes. I bumped the vcore up to 1.6 and the vdimm to 2.85 and am currently stable /crosses fingers. I ran a super pi in 38 seconds running my ram at 500 2-3-3-6. So I'm guessing it was my mobo....I have no idea what the problem was....but I know that things are looking up now.....wow....just wow. I guess I better pull my 3.0C out of the classifieds

nice see how far u can push that thing
Well it locks up after about an hour of CPU-Burn in at 250FSB. It Fails after about 5 hours of CPU-Burn in at 245FSB. Right now I'm running at 240FSB and have already had one restart after a few hours. I'm not sure what to think. I know it can do 250, I'm just not sure how to stabalize it. Upping the vcore does nothing, as I've gone all the way up through 1.55-1.75. I've loosened the timings all the way out as well....nothing. My temps are great. They never get over 30C at full load. This is frustrating.
You may want to try upping the AGP volts. On the IC7 that will also increase the volts to your North Bridge. Just might increase your stabilty, worth a shot anyway.

Yeah, I tried that last night, and upped it to 1.60.

u willing to try a different mobo now? u were able to get to 250 briefly was probably due to slight production differences in terms of board quality or some other reason. if u can make it there but not stay there regardless of vcore, then most likely its the motherboard. Like many peeps say, u need a droop mod to stabilize overclocks on the asus.
