Well its a start, no way to get your ram to 2000 ? seems a waste to run 2000mgz ram at anything below that. What muliplyers do you have on the quad ? 7x 8x 8.5x ? what is the next lowest below 9x ??? why cant you drop the multi and raise the fsb. I looked in the 9650 overclock thread, i see people using 8x multi do you have a 8x ? 8x ?
Yes neo i have tried even 1.38 vtt and still fails. Ram is 4gig and in the white slots 2gig of each module.Heres what it auto sets in bios when i put in 7-7-7-20 1t

Fails prime95 straight away core 3 on blend test and in small ftt it runs ok so its got to be memory settings i persume as blend test fails straight away and ftt test which only tests cpu runs on .

The CPU does have multiply options to go to 8.5 8.0 even 7.0.Quote:

Re: 2000 mem, sure it's a bit of a waste but I want to be linked and synced for best performance, L&S 2000 with this CPU means 4.5mhz. I only have a thin dual rad water cooling setup and I'm not just cooling the CPU the whole MB is cooled including the mosfets. I highly doubt this CPU and mother board combo is going to run linked and synced at 2000fsb with anything greater than 2GB of RAM.
I did attempt 2000 L&S once, it would not even post. I had to clear CMOS just to get back into bios. I may try it again later with just one stick installed but it would just be for chits and giggles.
I would try 1.92 or 1.94 mem volts and 2T instead of 1T. All 2GB modules I have tried won't even post @ 1T when overclocked.Quote:

If you give me the settings I will try it for you. And if it works I would be happily running 4GB instead of 8GB no questions asked...she would be screaming fast.Quote:

With 4GB installed the highest linked and synced I can posy is 1840FSB with the 9.0 multi that = 4.14mhz on cpu. Passed about 10 mins in memtest, tried to boot to Visat and it froze before hitting desktop.Quote:

This board + cpu combo with 4GB is maxing around 4.1 stable linked and synced.
Ran outta time will try some test with just 2GB of RAM, I bet it'll go much higher with only one stick.
Also I want to do some more test with 8GB, seems when one core fails in prime95 it allows the system to carry on priming no problem, may try disabling one core in BIOS to see if it's the extra load the 4th core add.
Its not your cpu, it definitly your ram, i know its made for nvidia boards, but im wondering if this board dont like your ram, i mean come on i put i7 memory 1600 and was able to 2050mgz linked and synced, and you cant even get 2000, something aint right, its not the quad holding you back, its that memory.
Im at a loss, 4gb at 2000 should be no sweat, im going to buy 2 more crucial sticks and run 4x1 and see if my settings will just boot right up. Have you tried the 4 gb in the black slots ? or only white ? maybe switch em. Just something you might try to, is try 2000, with p1 p2 disabled, see if that has affect, and try 8 gigs with p1 p2 off. I would have to say at this point 8gigs aint going to go, just to much memory to overclock, you should work on 4gigs. I will try 4x1 and see what happens.

When one of my cores fails prime95 with 8GB's it reduces the system stress just enoguh to let the other cores run for hours. It's a very fine line here.
I have tried P1&P2 off with 8GB no improvement. Even tried crazy relaxed ram timings, still NFG. I know there is a magic combo somewhere to get 8GB stable at 1800FSB I just haven't hit it yet. It's very time consuming because I have to reboot to test, more testing tonight.

I've used 4x 1GB Crucial Ballistix 2000 D9GTS, 8Gb Patriot Viper 2000 SLi Samsung HFC0 & 8Gb CSX Diablo 2000 D9GTR.
All were able to run UNLINKED at 2000 & higher but to run them linked I had to lower to 1800 as the QX9770 refused to do 500FSB (2000).
8Gb Patriot Viper at 2000 9-8-8-28 2.0V NB 1.60 NBGTL -0.08mV
8Gb Patriot Viper at 1800 8-8-8-22 1.90v NB 1.60 NBGTL -0.08mV
8Gb CSX Diablo at 2000 8-7-6-19 2.10v NB 1.62
8Gb CSX Diablo at 1800 8-7-6-19 1.95v NB 1.60
always with P1/P2 enabled
The most crucial part is NB voltage, it needs a LOT of it for 8Gb at high speed
loosen tRC: 50-63 & tRFC: 100-110 to test
Hope it helps, I had mixed feelings with this board, many joys & some letdowns, but what is sure is that it is a challenging board
WOW 1.60 on the NB, thanks for posting this info I'll try it for sure. -0.08mV is interesting. I've always been +mV for the NBQuote:

I still feel it's possible to get 8GB stable just a question of how much volts is it going to take and where.
Well this is where i am @3.8ghz prime stable for 47mins then one core fails really doing my head in any surgestions.Tried 1t and 2t same fails 47 mins here are the bios settings again.

I'll post the other settings when I get home, I feel like it's close, you might be able to get me there Rodriguez. You have given me more hope that's for sure.
Here's a 1 hour Prime run @ 1800. Same settings as my 1780. I'll try to bump it up more when I have the time.
Cant you run cas 7 on those patriots if there only running 1800mgz ? seem like they should cas 7 easy, heck if your going to lose 200mgz, might as well get better timings. My crucials do cas 7 easy at 1800mgz. Trigger i think you might have to compromise, maybe get you quad to 3.8, 3.9, and get your memory to 1900mgz so your sort of losing a little off both ends. Have you tried running unlinked at all ?. Another thing, i wish you guys would post your bios setting in a template, makes it easier to see whats going on.
Here Trigger try these settings, should be very close to working, and gets you pretty solid. I find it hard to believe that he is running 4 gigs at 1800mgz with only 1.42, very hard to believe. I know on my 2 gig kit 2000mgz linked, if i drop down one notch in nbv, it will not run period, i cant get my 2000mgz linked without at least 1.54 1.56 nbv.

Right, my system is totally stable like that. No probs, but I can't get my Q6600 to 3,6 ghz as it needs 1.52 in Bios, with loadline enabled. Cpu-z reports vcore as 1.6. So, I am wondering if I could clock my RAM to 1600mhz. I know someone who had exactly the same ram as me, with this board, and got them 1600mhz with 9-9-9-24-2T @ 1.6v in BIOS.
I naturally did the same, passed 17 passes memtst, but froze after 5 minutes in Vista. Any suggestions?

But there are "golden samples" out there that require much less voltage to do the same, just like CPU's. I had the "oportunity" to own up to 4 x Striker 2 Extreme & they all required different voltages to run the same mem speeds, my last board was my best. That's also one of the reason's why there was a Striker II NSE version with lower mem speed, those boards got the "bad" chips that couldn't do 2000Mhz at reasonable voltage.
The 8Gb Patriot Viper kit I owned couldn't do CAS 7 even at 1800 totally impossible, the Samsung HCF0 in general are rated for high speeds with loose timings.
The 4x 1Gb Crucial could do CAS 7 at 1800 & at 1890, but the best was the 8Gb Diablo, it went to CAS 7 at 1850 with 8Gb but required very high vNB.
The setting of NBGTL -0.08mV, is what I needed for my particular chipset with that 8Gb Patriot kit with the QX9770 at 450x9 linked/sync. I started messing with NBGTL after finding out that more vNB did not do the trick. You will have to fine tune yours after finding out what vNB you require for your board.Quote:

Personally, I've run three different Striker II's and still own 2 of them. Each has it's own "qualities" to them, mostly from the temperatures and the amount of over volt they produce. All seem, relatively, the same in regards to the amount of voltage I need to run at a given speed (give or take 0.02v.) Temperatures on the other hand, vary somewhat dramatically.Quote:

As u can see always bang on 48mins it fails.
i lied when i said 1600 fsb and 1333ram was stable, as it bsod when I left it alond for 5 minutes. I'm trying out the settings you gave me Neo Mike. How do I know when to raise NB GTL?
EDIT - I was going to poast that ANY setting I have been trying was unstable. But, just realised, Loadline Calibration was disabled, and it was the cpu being undervolted all along. Damn, 6am - 3pm shift work has numbed my brain today. :(
VTT is a bit high for 1600 fsb? 1.42v? PLL would be 1.52v if I set it to 1.5 in BIOS anyway, so thats fine isnt it?
EDIT 2 - It was quite unstable with ram unlinked, even though both were 1600. Linked and synced a lot more stable.

I thought these settings were stable, 1 hour OCCT, 30 passes Intel Burn, but I left it for 30 minutes, and it had restarted by itself. Any ideas?
Last edit- Found that too high NB was causing my instabilty. Rememberd that I only have 2 sticks of ram, and dont need that high a NB. I set it to AUTO, which gives it 1.33/4v actual, and its stable. Such a crazy and nonsensical board.
I am water cooling(NB 48c idle), thanks to all you guys for the tips. I'm still trying to get stable with 8GB. Playing with NB gtl now.Quote:

yeah fun...cpu gtl's pia. I did play with them before but found no stability have since gone back to auto.Quote:

Try the 1900 setting i gave you, that will get you 4.0 ghz, and 1900mgz memory, but only on 4 gigs.
tried 8.5 1900 fsb, won't post at all with 8GB's. I'll try 4 later.Quote:

Prime95 Blend is running stable (10 mins at least)
Compare Sangrak's 1800 linked and synced.

What's really interesting is the mem performance here. Check out this bench mark.
Well that was going to be my suggestion was to go unlinked. Now you should up the fsb to 2000, drop the multiplyer, and that will boost your ram speed, heck if you can get 1900mgz out of that ram, you may have to just call it all good.
I had another question for you, on the other settings you were running, do u use the lcd poster ? you say it wont boot, what kind of error is the lcd poster giving you, dram error ? code error ? cause that tells you what is going on, if its a dram error, when i get that, i have to increase nbv to make it go away. The problem with those everest shots are, the latency is horriable 52.1 sucks to say the least, you need to be around 45.1
My overclock is stable when I'm using the pc, but if I levae it alone for more than 15-20 minutes, it always bsods and restarts. Settings are:

I just ran Prime95 blend stable @ 8GB 1800 linked and synced for 54mins before one core failed.
Seems the trick has been a combo of things, one I wasn't using my OCZ RAM cooling fan because it wouldn't fit the higher Patriot heat sinks. When I was testing 4GB I noticed how much cooler they were, packing 4 sticks together so close was increasing RAM temps by 20c at least. So I modded the fan so it'll fit, RAM is running way cooler now max it'll hit is 50c.
RAM 8-8-8-22 with tRC=46(auto) tRFC=110
NB is at 1.60 with -0.08mv GTL and get this RAM volts to 2.04. This got me 54mins in Prime95 blend, I had tried high RAM volts before but it didn't help because the RAM got way too hot because I didn't have the fan hooked up. Trying RAM at 2.06 right now to see if it'll go past 54mins.
If it does I'll be trying to back off NB volts to see if 1.60 is really necessary and I'll try and tighten the tRC down.
EDIT:Whooo hoo + 1hour Prime95 blend stable at 2.06 mem volts. Sucks my RAM needs sooo much volts but I'm just glad I have a stable base to work from now.
Been doing some research on the gtl voltages, went back early in this thread,seems like anybody with a quad, and 4 gigs of ram or more, had to set gtl voltages to get stable, so here trigger try these gtl voltages, cant do any harm, i think it will improve if anything, good luck. This screen shot the guy has a 9650 quad.
Hey Joe, i think your memory is probaly causing your problem, you memory is rated for 1333, dont know if it can clock to 1600, it should, but that would be my guess, run memtest 4.0 in windows and see if your memory passes, then run prime 95, small ffts where it test mostly your cpu. Ok joe after looking again at your template, TURN ON LOAD LINE CALIBRATION , ENABLE IT. Your vtt is way to high on auto, you shouldnt run auto voltages, set vtt to 1.32-1.34, try nbv 1.50 -1.52, and enable p1 p2, cpu pll 1.52, then run the test i told you. To much vtt voltage is know to kill quads.
Yeah, I set RAM to 1066 all settings on AUTO, VTT to 1.32, PLL to 1.5. All running sweet. Ran Intel Burn Test whilst watching a fullscreen movie. I find that this is a quick way to find instability. Also, Vcoe is now 1.35 with Loadline Enabled.
I'll loosen timings to 9-9-9-30. Also, should I set 1T or 2T? 2T is unstable with 1066 mhz. AUTO timings are 8-8-8-20 1T @ 1066 and it runs sweet like that. 2T is unstable @ 1066.
Well i thought it was your memory, i would suggest you get some ddr3 1600mgz ram, its very cheap, cause your ram is stoping your from overclocking your rig at all, 1066 thats ddr2 speed, but at least your stable for now. It should run 1t, and you should be able to run 7-7-7-21 at that speed easy, my ram is rated for 9-9-9-24 at 2000mgz, but runs 8-7-6-18 1t easy. Here is a link to some good ram that will run on this board, and overclocks to 2000mgz, and its pretty cheap.
http://www.newegg.com/Product/Produc...82E16820148223
Thanks for the link neo. But I won't go for those - yet. Forgive me, but i must try to get these to 1600. Problem is, I've only got 2 sticks in at the moment, the other 2 have been sent for RMA about 2 weeks ago. So really, I shouldn't be playing around because it's all gonna be irreleveant when I add two more sticks. But that's just me.
Gutted about my Q6600 though, it's stable 16600 x8 with 1.325 vcore with LLC enabled. But needs 1.475 with LLC enabled for 3.6ghz. It's a 1.3 VID chip, L807A413 batch. And I'm on air, so heat is an issue with that kind of volts.
EDIT - Tried 1.62vdimm, 9-9-9-30-1T. trC:50, trFC 100. It ran sweetly for an hour or two, but again, i left it for 10 minutes and had restarted. Any ideas?

What did the event viewer say happened? Might be worth a look.
Event viewer shows an error "The previous system shutdown at 23:24:17 on 01/03/2009 was unexpected."
So I look at 23:24:17. And there's no errors there. Wierd. Also, should I try NB GTL tweaking? I know it has some effect because Vista won't boot with +10mv. But is fine on AUTO. So might need to fine tune that?

Thanks Rodriguez!!!
Appologies for the Nob question. Iam thinking of changing my Asus Maximus to ASUS Striker 2 Extreme with the puprose of running 2x gtx8800 OC in SLI on it.
(getting cheap on the vga) and i also have the chipset for watercolling all the mosfet,cpu, nb,sb ready. so i dont want to pay the extra $ or £ for new hardware.
Does this board gets 450 FSB? or iam going to hit the wall.
iam thinking of getting my CPU 8x450 QX6700 (runs 100% on my current setup)
Will have to get new memory though. Any suggestions are welcome.
I have the Q9650 at 450 Bus. I can't say it'll do it with the QX6700, not sure I've seen anyone running that combo.Quote:

Neo Rtr, Can be done, i dont have a quad, but im sure you can do it, but will definitly take some work to get there, have to play with voltages, gtls.
I would get some crucial ballistic ddr3 1600mgz or crucial ballistic 2000mgz kit, im running the 2000 kit, great stuff. Getting your quad to where you want it will be easier with 2gigs of ram, more hard with 4 gigs of ram.
yep, 1.33 bios with LLC enabled = 1.44 1.42 cpu-zQuote:

Thats insane, what bios u running ? my 1202 bios dont over volt even close to that. 1.28 bios , everest 1.31
For me 1202 bios LLC enabled bios set 1.34375vcore = 1.39v CPUz or Everest Ultimate CPUID or CoreTemp
Have you tried 7-7-7-20 2t timings with 2x2 seems to me if your kit is the PVS34G2000LLKN rated to run PC3-16000 (2000MHz) 9-9-9-24 @ 2.0V then it should be no problem. If it doesn't they may need rma'd too.
Did you ever post all your bios settings if not grab my template a few post back and add your settings to it.
Who you refering to owncraftsman ?
Ok this is wierd. My pc is more or less stable now, need to iron out some issues with ram. Never had a problem all day yesterday.
I started it from cold this morning and POST froze on USB INIT. Any ideas why?
Thanks for the notes guys. will look at this further.
thank you
OK, found out that this USB INIT freze during POST is due to me setting fsb and ram to linked and synced. If I set to unlinked and both 1600 it is ok. Any ideas?
I'm using BIOS 1202. It is what it is, could also be the board reporting it incorrectly.Quote:

EDIT - nvm, I'm just going to stay at 3ghz with ram linked and synced. It's happy and stable. Just spent 3 months trying to get it stable at any setting without success.
I've been told that the L807A batch that I've got, coupled with this board is hopeless. I've been told that if I want more, go 45nm.
My hard drive errors and BIOS freezes only happens when overclocking. It's sweet now at stock settings, so something is disagreeing with something.
whats a good program to test memory in vista itself.As if i do small fft prime 95 runs all good but when i do blend it fails like straight away.
dowload memtest here http://hcidesign.com/memtest/MemTest.zip you can use it while in windows.

even though the cpu can pass in small fft and not in blend i would surgest its not the cpu .Could be i need to set memory values rather than leave them in auto @ the moment i got it set @ 7-7-7-20 2t and rest in auto.Im using bios 1202Quote:

ok will try that heres some pics of bios settings and real voltage values in everest.

tried these settings and i got failure in blend staright away.
Did you up the vtt to 1.32 ? pll 1.56, put your ram at 2.00 v Your vtt says 1.26 way to low, i dont care what everest says for now, you can always lower later, you have to set hight to begin with, and pass orthos first, then lower later. You may still have to up your nbv, this board takes alot nbv to run linked n synced.
Ok applied your settings running prime95 now will see if it passes the hour mark as always before fails bang on 48mins.Quote:

It needs around 1.45vcore to stay stable at 3ghz. Which is quite nasty.
My ram can clock easily up to 1600 mhz, is it worth setting it to 1600. The only thing is that would be higher than my fsb which is 1333. Would I gain anything with this?
Failiing this, would I gain anything from tightening the timings a bit?
I have seen q6660 do 4 gigs. The best performance on this board comes from linked n synced, when you go unlinked you lose performance, but you may have no choice, i would sell that q6660, and get a q9650, $275 brand new on ebay, then you hit 4+ .
my goal is really to hit that 4ghz on this qx9650 chip on this board in the past i needed like 1.5vcore to hit 4ghz which i think was really bad .So if we can get this stable now at 3.8ghz with the above settings we may be able to move up slowly till we hit the wall, i could not beleave what was so extreme about this chip as orthers needed far less voltage to hit 4ghz.
Yeah, been informed by a number of guys on the corsair forums and elsewhere that this particular batch of cpu doesn't do well at all. Someone else with a slightly similar batch number can't get his past 2.8ghz.Quote:

What could I realistically achieve without watercooling this board?
For reference, a NB voltage of 1.45 gave me max load temps of 55 degrees celsius.
You would have to change the nb heatsink that can be done for $35, and will drop your temps into the 30s idle and probally around 50c loaded, or you can go watercooling, but to me its way to much money, and over rated. Then you could buy a good cpu cooler for $35 that would cool the 9650 very well, so its much cheaper to buy heatsinks, than go water, and i find they do a good job, im 37c idle 40s full load, then the sky is the limit, im running 2040fsb linked n synced with those temps, i have room to go higher, but memory wont go.
Also water cooling is only as good as your RAD and fans, I'm using a small dual rad and trying to cool the whole MB, not really as effective as good air cooling. I need to add a second rad and better fans to get better cooling.Quote:

Attachment 95910
wow, well has to be not enought voltage somewhere, give 1.34vtt, 1.52 nb, make sure you memory is 2.0v, try again.
Ok will try again tomorrow thx for ya help for today.Oh and i forgot to mention at stock settings 1.(1333x9 unlinked 1600 and memery settings 7-7-7-20 1t and all orther memory settings on auto )2.(cpu voltage settings everything on auto except for ram v.1.84 and nb v 1.42 with loadline disabled it can pass prime95 on and on and on no problem.So its only when i overclock the cpu im getting this failure at 48mins @1600linked&sync x9.5 3.8ghz so what do u think could it be i need to crank up the cpu vcore as if memory passes @ stock settings we might have to rule that out.Also gtl settings i have tried loads of combinations to no aveil.If i set the cpu vcore to like even 1.325 and llc enabled it can run for ages in prime95 on small FFT,But test it in blend its a BSOD.:down:
Can tuning NB GTL have any effect on stability?
My OC can't stay stable at 1600 fsb even with 1.5v NB and 1.55 SB. The CPU passes Intel Burn for 20 passes. But it will bsod and restart itself after 30-40 minutes.
I think the mobo may not be liking it for some reason. RAM is set to 1066 (3:2 ratio).
How do you calculate NB GTL?
VTT is set to 1.36 in BIOS (1.38 actual).
Yes nb gtl can help with stability. Why are you running memory at 1066, we have been thru this how many times, your not listining at all. You have 2 9800gtx in sli ? how big is your powersupply ? what voltage is your memory at ?.
I was running memory at 1066 as someone on here told me that any ratio other than 3:2 1:2 1:1 will NOT work. I may have got this wrong, but my instabilty also happens when ram is 1333 and unlinked.

yes, running 2 9800GTX+ in SLI with Zalman HP-1000 watt PSU.
All I'm saying my system always reboots after 30-40 mintues after running intel burn test. It'll pass 20 then if I leave it alone idling in desktop, it will have restarted on it's own.
i have also tried RAM at 2T. It still restarts. I have tried RAM at 1066 and 1333, restarts.
Joebloggs,
Just for a laugh, start the CMD prompt "run as administrator" and type sfc /scannow
Maybe windows is corrupt?
I'll try it tomorrow.
I can clock up to 1333 fsb easily. (3ghz). No problems runs sweetly there.
If windows was corrupt I'd be getting random bsods with stock settings and OC'd 3ghz settings as well right?
This is a brand new install of vista 64 bit. Installed with all BIOS settings on default.
ALSO, will try 1.5v for NB. Maybe SLI setup needs more NB?
I told you before you memory voltage is to low, needs to be at least 1.75 1.85 volts, i dont know any memory that runs at 1.6, only i7 memory, and that runs 1.65, jack up your memory volts for starters, that alone could fix your problem, your undervolting your ram by alot.
X2 christ I couldn't even post with less that 1.92mem volts when I first got this board and OCZ 1600 RAMQuote:

Mike, whats up with the tripple channel kit you were going to get? (high-end one)
What other plans you have for this board?
I got big plans for this board slim:rofl:. Im not sure what kit to get, heard the csx diablos do 2100 on this board easy, lot of nbv, but they will do it.
I want the Adata 2133mgz, or Corsair GT 2000 cas 7, but havent seen to many overclocks with corsair kit, want to see what people are hitting on those. I dont know what else i can to the board, thought about a 9650q, but alot of work to overclock, and get ram to 2100, aint going to happen, that i promise, rather keep my e8500, and have ripping fast ram.
I would like to put 2 gt 295s in sli:up:, but dont have the cash right now for that. So im just enjoying my board, would love to ln2, and push it to brink of blowing, thats in the future.
What are you plans ? when in the world are you going to get cooling ? gosh Slim go buy a $30 cooler and take off your nb junk, and it really drops temps, so you start overclocking that baby.
Diablos would be good, but D9s are getting behind compared to the new Elpidas so I would recommend trying Tripple Channel Elpidas as you will have an extra stick for the future when you migrate to i7.Quote:

My plans, well one day I will have the money to finish my water cooling project that I started back in August. I really want to overclock this thing but oh well. I also get lazy when I think about getting everything out of the case etc etc. I guess Im not really motivated since I was really hopefull to have my system watercooled and ready long ago.
