I have this kit KHX2000C9AD3T1K2/4GX

I ended up buying three of them so I could do 6GB in my X58 box and 4GB on the P45 rig plus I have one extra stick.

I can still return them, I want at least 1600 cas 7 and if I can't get them to run that then they gotta go.

i had a few sets of bbse and i had tough time with them on rex 1 set toped off 1600 cas7 other sets 1700 cas8
the 2200 cas7 pi toped off 1920 cas6:up:
you need microns or hypers
there are a few sets with micron in sale section;)
i would grab these hypers soooo fast

i have horrible luck with getting low VID chips

That's not always a bad thing, lower VID sometimes equals higher heat.

So far Prime95 table...but definatley appreciate any insight that might tighten things up a bit. Basically, I started with ET6 to 4.05, added PCI=100MHz, upped CPU V1.34, backed off DRAM to standard (2.66D) @ 1200MHz and left everything else auto. I'm not so sure she should be cooking at 72-73 only 10 minutes, but open to suggestion :) after reading through much of this it seems the MCH and VTT are where a lot of the sweet spots lie? but I'm not sure what I should look for there.
Thanks for your help!

Your PLL and VTT are off the charts. Set PLL to 1.50 and set VTT manually, about 1.32 just inch your way up. Usually it stays just below vcore.

Thanks for all the help!! Things are getting better...

I'm still working on tunning things up a bit, but I thought I'd share progress and see if anyone could offer additional ideas that might help stabalize.
The system runs great, but still BSOD/Reboot under Prime95 within 10 minutes. Temps have cooled off several degrees C, and I gained an additional 100Pts in Passmark score by boosting my RAM just need to stabalize it under load and things will be great.

For starters dont bother with the 3.33D, it doesnt run at its rated speed, instead use 3.20B. If you want to see the difference check the bandwidth on each.

Thanks HOSS, I'll have to check that out tonight - I actually made some other adjustments late last night to MCH, and VTT/Vcore -the result was slightly lower temps and faster Passmark score (by about 100pts)
I think I'm getting closer - I really wanted to try to get the RAM as close to 1600 without stressing it but it seems pretty touchy.

First turn off cpu thermal protection, then enable vdrop correction, because to me it looks like its not turned on, since you have 1.325 Vcore set and you are seeing 1.23 at cpuz.

Next set your vtt to 1.2 and then set your cpu ref to 0.785 and the mch ref to 0.800, and then go back and set vtt to desired voltage i.e. 1.30 as you have selected.

Give that a try now:up:

Done and Done - you guys rock!

Took sil3nc3's advice and made the necessary adjustments. didn't want to take a chance on lowering my RAM settings just yet - I actually want to get that all the way to 1600MHz at some point.

I'm running Prime as we speak and getting much better results - OH - I regreased by cooler as well (used cheap thermal grease last time, and found my bottle of Zahlman's ceramic) makes a difference for sure.

I'm 5-7 C cooler, OH and I lowered the VCore, with the droop I noticed it was actually running 4GHz loaded using as little as 1.248 CPUZ, even though I had set it to 1.34BIOSv (so I lowered it to 1.275BIOSv with calibration (prevent droop) and its running Strong at 4GHz and 1.248vCPUZ

Thanks all for your help! If anyone can recommend anything else I could try to fine tune it that would be great. I already tried lowering the voltage in small increments - 1.275 seems to be the lowest it will run...what about some of those other values - should I now try adjusting them higher or lower to gauge impact to performance, temps, etc?

Thanks for all the help!:D

Going to 3.20B from 3.33D is by no means lowering your ram settings. Like I said earlier it doesnt run at its rated speed, its bugged and really only a 3.0, so at 450fsb your ram is running at 1350 not 1500. Heres a couple everest benchs for you. :up:

Do you really think I can run cas5 if my ram is actually at 1500 and still have lower bandwidth than 1440 cas6. ;)

Are there any specific settings Imight want to work with (DRam voltage, etc) when I try to make that change I get boot failure fron windows and frequent BIOS lockup before POST completes, it was hard just to get back in and change it back before it locked up - really didn't want to have to redo all the tweaking (havn't been great about saving it as I go - changed that now of course)

Thanks for all you guys help

EDIT - on a separate note - I seem to be performing very well and Prime Stable for at least 30 minutes (yeah I know its not like 2 hours or 24 hours as some like to run - but I stopped it when thermals on one of the core's crept up to 74C, am I being a little over protective of my chip or do I need to look for ways to improve my thermals before continuing to attempt longer prime runs?

What ram kit are you using? If your only at 1.6 vdimm now you may need to bump it up some. As for your temps I wouldnt worry about them to much at this point as long as they dont go much higher during prime.

rated up to 1.65v I believe, I tried 1.64 with no luck, next option was 1.67 but I wasn't sure how high I should take it over the rating

Do you still have your mch voltage set to auto? If yes than set it to 1.32v and also disable xmp.

sweet thanks! I'll give that a shot...I got my thermals way down finally - in the middle of a prime run at only 63C right now...which is much better (new grease, new fan, and needed to turn one of my intakes into an exsaust since my rear exsaust became an intake (for the Corsair radiator)

I'm hoping this will run for at least 2 hours, then I'm off to play with the ram again...

Yeap - the RAM sucks, or I suck, and since I'm not willing to face the reality that it is me, it must be the RAM, I just can't squeeze any more performance out of it...on the other hand, I finally confirmed I'm 24hr Prime stable and incrementally lowerd my Voltages to 1.2875, thermals are much better - never above 69c and generally average 60-64c. (loaded) and idle around 39c

b1t, put 50 on your MCH skew, and raise your CPU termination, you will get a lot farther.

Thanks 'Guru, I'll check that out! - my understanding is that VTT should pretty much always stay behind the CPUv -is that right?

Most of the time, I usually stay about .2 behind till you start getting really high clocks. So if my vcore is 1.40 then term will be about 1.38:up:

Hi! I just got my new Q9650 CPU ! I am using it on an asus maximus extreme x38 mobo! Right now it is OC to 3.6GHZ and cpu is quiet happy and cool!

here is my retail cpu information:

Pack date: 5/3/2010
FPO/Batch: L009B453
S-spec: SLB8W
VID: 1.2250v

you need to change your username to Q9650,i think your new cpu is upset:D
seriously though,the x38 isnt a great board for these quads,but still you should post
your bios settings for people to help.also is the maximus extreme an x38 board?

ok im not 1005 familiar with the x38 but have used the x48 and i do know the NB
voltage required for my quad at higher fsb was a lot.i would start with loosing up
your ram timing and focus on the cpu first. try more FSB term voltage-1.26v and cpu pll-1.57v
give it a little more vcore and test to see if its stable and then start dropping vcore.also try 1.42v NB

I have that same combo in my setup now under water. That Q9650 will go higher under that board if you give the NB the juice it needs. Mine operates in the 1.57V area to keep it stable crunching 24/7 at 4.05 GHz. Then again it's also watercooled and not using the stock cooling. My CPU Vcore is at 1.28 if I remember correctly (I'm at work right now).
07-07-2010, 02:22 PM
radaja

yea thats what i was thinking too.i couldnt remember the NB voltage needed for my quad
on my rex but i did remember it was a lot more than the P45 chipset.

I am worried about load temp it gets to 65degrees ! summer heat is holding me back! I can reach this OC thanks to my corsair h50 cooler! but with a vcore of 1.256volts at 3825mhz is simply impressive!!!!!!!!!

Just a heads up for all you 775 Quad o/cers out there (and dualies) - all 3 of my P45 boards are up for sale - all in great condition and fully functional:

http://www.xtremesystems.org/forums/...d.php?t=255084

I'm open to offers btw..

Q6600 - looks like you need a better board, you could probably go even further with lower volts on the USB3P, and you'd get to keep you DDR3! ;)

hey fellas,

not been OC'ing for a few months - hungry for more!!!

any pointer??

Q9650 @ 4.95Ghz 1.275v

vFSB - 1.26v
9*455
DDR2 @ 1093 5-5-5-15 2.14v
gtl 1 - 0.675v
gtl 2 - 0.675v
pll - 1.56v
vNB - 1.26v
vSB - 1.1v
LLC - enabled
All spectrum controls - off

asus P5Q deluxe on 2301 bios

it took ages for me to get this OC stable - when i try an boot at 460 i get problems - i'm fully liquid cooled - so i'm not too bothered about high vCores -

i'm thinking - 470@1.3v vFSB : 1.28 and move my ram down to strap below as its only 1066

any tips??
08-03-2010, 12:35 AM
grishenko45

update ... i'm now stable @ 4.212Ghz :) vCore @ 1.325v vFSB @ 1.3v pll @ 1.56v vNB @ 1.28v thats 468*9

boosted my 3d mark 06 cpu score up from 4.095Ghz by about 450 points!!

cheers!!! hey - i see in your sig you've got a q9650 @ 4.8Ghz - what board and what PLLvoltage u got?? do you think my 1.56v PLL is too high?? thats the only voltage i'm concerned about - i'm fully liquid cooled but i dont want to fry the circuits !!

any tips - whats your PPL voltage? and what gtl refs u use?? i'm on x0.675v for both - seems to work better and give higher Gflops output that when i had them on 0.667..

With 45nm ~1.60 vPLL is the soft limit, so keep it under that, preferably under 1.57v

Pretty sure NoGuru used a UD3P for those clocks, its widely understood to be the best board for overclocking quads.

Raw CPU stability (Prime95 small FFT's, LinX) is pretty easy to do on most boards up to a point, its Prim95 large FFT's and long blend runs that really expose instability. You may find it tough to pass especially with 4GB+ ram installed. You would want to run a few hours large FFT's or blend run to be sure you're stable.

grishenko45

thanks cryptik - gonna say - for a 533mhz fsb on nogurus quad - its got to be a gigabyte!

i use 20 loops of linx - then game really heavily for a weekend - i recon 20 loops linx is enough games is where i've found all my instabilites with all my other cpus - when p95 was 8 hours stable games BSOD - so since then i just do
20 loops linx and hardcore game for a few days!!! good enough for me!!
08-03-2010, 06:06 AM
CryptiK

Sure whatever works for you man, stability is subjective anyway. Just passing on what a few of the Q9650 boys in here (and myself) prefer to do but it's all just personal choice of course. Most guys run vPLL between 1.50v -- 1.60v but lower the better, only raise a voltage if you need to!

Yep, EP45. I don't have time to check the settings right now but I think I use 1.57 PLL and .785 cpu and .800 MCH refs.

I use prime just for the temps being lower then the rest of the tests out there.
