I don't know, the cpu is more energy consuming and it's certainly harder to feed it with voltage at a particular value in comparison with a dual core.Quote:

I've seen on the quad database that apparently all the new L8xx are at 1.325V VID and that oc sucks too.
Other people have confirmation of that? I'll be testing my L804A tomorrow maybe or a bit later.
Anyway I've finished lapping it

you can check out my L804A a few posts up, 3.2ghz at 1.32v is ok imo, maybe i will see what it takes to get up to 3.6ghz.
well.. just tried for 400x9 with 1.46v load and it was not OCCT stable. I don't feel like trying higher with this MB :cool:
dangit GEN you're making me fearful that my l804 is gonna suck! I guess I can always go rev isioned 45nm quad :P
Pacha, those are some nice shots of before- and after-lapping. One thing I noticed on your PCB code, it starts with 2L7 instead of 357 like we see here in the U.S. most recently - I have yet seen any L80x with the 2L7 code, which used be shown on those glorious batches of the year 2007 production. So it bodes well for you. :)Quote:

Unfortunately, it requires 1.325v to stabilize 3.2GHz (all cores < 58C), and a whopping 1.425v for 3.4GHz. Didn't want to go even higher as I wasn't inspired at all. The chip was returned back to the store.
Keep us posted with your results!
1.325 bios volts or loaded volts ?
Sorry, all the volts in my last post mean BIOS settings. And I enabled the load line calibration.

Just to add some info on what you were answered, on points 1 to 3:Quote:

If we accept a normal envelope set by intel as 5%, and consider 10% to be a safe margin, these 65nm chips wouldn't die so fast up to 1.5v +10% : 1.65v. So, even with vdroop bypass techniques enabled, you'd be safe with a bios setting of 1.55 vcore.
About the temp, I'd monitor with coretemp. Personally, I feel anything higher than 69°C with Prime95 small FFT is too hot. But, 69°C in Prime95 small FFT won't exceed 60°C in most usual daily tasks, even video encoding
As of 4GHz, forget it on air for 24/7 unless you are at constant 10°C ambiant. On water, only few selected and valued chips will do it, so forget it too. 3.6GHz is sweet spot, 3.8 GHz on many low vid L7xx batches and 3.9GHz on some L7xx batches with quality motherboards (P35 for full stability)
My chip can do 3.9GHz stable P95 small FFT at 1.47v. For memory bandwidth issues, I opted for 3.84GHz
This is only when you exceed 1.50v to 1.55v on the vcore for a quadcore on high quality PWM motherboards. On lower end models, it will be a problem as you exceed 1.45v, sometimes beforeQuote:

Hey guys,
I am looking for a store who is known to carry low VID q6600's. I know it's a crap shoot and not all stores are willing to take the time to show this stat, but is there anyone out there who will let me hand pick one (online) based on VID? My buddy just got a newer batch q6600 as well and it had a 1.325v VID. Mine is 1.275v. 865pe's VID is something that I would like to jump on (VİD 1.2125 seems really low)...
Thanks!
The problem is, the VID voltage is not on the package. you really don't know until you install it and fire it up.
The best Q6600's are the one that start with L7. You need to find a store that still has them.
My lapped Q6600 GO (L726B397) with a default vcore of 1.224v's, only requires 1.392v's to make 3.6GHz stable.

I have it set to 1.4-1.55v depending on...my mood, really :)
I have never had issues with the vNB with 2 or 4 sticks.
I also went a step further and removed the Chipset Heatsinks, cleaned the factory crappy putty off, and put Arctic Silver Ceramique on the NB, SB and Mosfets that are covered. I also did the same thing to the Heatsink that is above he CPU at the top of the motherboard, plus I have a 120mm fan blowing down on the RAM and NB. The NB is not even warm to the touch.
That might explain why I have virtually no NB issues with heat.
*my q6600 is lapped as well, along with my "Leaning Tower of Pisa" Thermalright Ultra 120 Extreme
Great, nice to hear if I ever decide to go with 4Gb RAMQuote:

I'm also sure that people taking care to cooling the motherboard and reseating the default heatsinks will have better performances by far. For stock radiators, you also have a very good overclock on a Q6600 + 4Gb Ram on air, as I removed them all and replaced with thermal righ heatsinksQuote:

not sure I follow you. I took off the thermal pads on all heatsinks and added the nonconductive Arctic Silver Ceramique, not added to the thermal pads. The Arctic Silver Ceramique makes great contact with the mosfets as I test fitted them, and the footprint "smear" was great.Quote:

- The mb PCB is not hard, it bends, always... less than 1mm, but it bends
- Fixing of the heatsink is made by two push-pins on the extremities only, so impossible to solder to middle of the heatsink when the PCB bends
- Finally, ASUS heatsinks are really light aluminium without any surface polishing or special care.
It's not without a reason that all reliable third party manufactures of optional mosfets cooling kits recommand thermal pads for cooling mosfets.
This is also the case on VGA cards when cooling memory chips: you need either separate heatsinks per module, or the use of a thermal pad for many modules under the same heatsink because of the always uneven surface between two chips
Hope you understand better now what I meant
I made the same mod as he did with my first and second Commando and I must say the contact is quite good, putting enough as5 for the sink to cover them all, the results seem correct.Quote:

Or you may want to put a fan blowing on the mosfets near you cpu to feal at ease.
ah, yes, ok I get you now.Totally makes sense. I, too, realized that the mosfets were staggered height and was wondering how much that would effect cooling. It's worth a try to put the thermal padding back on...but obviously mine is rolled up in some trash heap somewhere.....
Where would you recommend, if you can actually buy them, thermal padding?
The only stuff I see are thermal compounds and not physical padding kits...
Thanks!
It can be enough for a C2D, but clearly not optimal. And it won't be enough on a quadcore with vcores above 1.45-1.50v, overclock will be limitedQuote:

WIth a 1.325vid q6600 what would the ideal 24x7 vcore be safe under good water?
I'm guessing 1.55? maybe 1.6? Planning on the chip lasting a couple years.
I'll be needing 1.5V likely just to hit 3.6ghz on my L804
Since everyone is talking about their vid, mine is 1.2625v and I need 1.47vcore to be stable at 3.6Ghz, either 450x8 or 400x9, doesn't matter. I have tried 4Ghz, 450x9, but even with 1.65vcore it was not stable, although I was just doing some quick testing. I am going to try and get 3.8Ghz stable, but I think the consensus is that anything over 1.55vcore (actual) 24/7 is not good for the chip regardless of how good your cooling is. Speaking of which, under OCCT and P95 both running, I don't exceed 62c. That's with an ambient of 24c. My batch by the way is L726A820 with a pack date of 8/21/07. I haven't found anyone else with that batch, so I do not have a reference on what I should be getting, but base on some other vid's that are close, I think I am doing pretty good.
Utnorris
Hey Utnorris, I've got the same vid...these are the settings I'm running at (this pic was with P95 doing blend in the background):
http://img115.imageshack.us/img115/6348/466x8cr8.jpg
Small FFTs temps are around 65C with the current voltage, and upper 20s idle. I ran P95 overnight at 1.47v (bios) and it failed, but my NB voltage was only at 1.4 so that could have been the problem. I'm trying again with 1.45 NB and the next step up on the vcore and I'll let you know how it goes.
Clubit.com just went out of business. I bought by "GO" stepping from Clubit.com Is there any other online etailer that guarantees "GO" stepping processors or are the noobs just rolling the dice?
you can try TankGuys @277.99 they are guaranteed G0 steppings I believe, if not then contact them directly.
I would be suprised if there are any B3's still rolling around.
pretty much every e-tailer is g0, listed or not. it would be extremely rare to get a new b3.Quote:

Also, what is your cooling solution? 20's seem really good as I sit at 40c under idle @ 3.8Ghz. At 3.6Ghz I was idling at 35c. Oh, my NB was at 1.58v.Quote:

By the way here is a screen shot of OCCT with the 3.8Ghz stable.
Utnorris
By the way, how did you get real temp to work? I keep getting "driver not installed" error when trying to run it.
Instead of explaining my cooling setup; here's an awesome picture (joking, lol):
http://img361.imageshack.us/img361/5088/airflowwb7.jpg
Lapped w/ 21-22C ambients (explaining our difference in temps since yours is 6C higher)
I have the G.Skill F2-8000CL5D, but I'm only running it at 800mhz and 4-4-4-12 timings right now. I haven't tested the bandwidth on that compared to 1000mhz yet. Also, it seems like the jump in voltage/temps on our VID from 3.6-3.7ghz to 3.8+ is more than it's worth...but then again I plan to run my setup all day for gaming so to each his own I guess.
I didn't do anything special to get real temp working.
Oh before I forget, that was one nice lapping Pacha!! I think that beats the lap...dance..I got at club la vela, lmao! Care to explain the method you used with the glass/paper?
ok here are a few results of my L804A515, pcb starting with 2L7, very disappointing at the moment I must say :
Idle 3.3G 1.4V vcore :
http://www.hostingpics.net/pics/4990...1.40V_idle.jpg
so it is 1.325V as others L80X
a few results :
3.2G 1.40V stable
3.3G 1.40V not stable
3.3G 1.425V stable (with 1.3V vFSB)
3.4G 1.425V not stable (5 seconds OCCT)
3.4G 1.450V not stable (BSOD after 5 seconds)
I'm running with 1.35V on NB for all of these, raising it up doesn't help. RAM is OK. Temps on full and idle are all right, and load temps don't increase much with vcore as some people reported on high VID CPUs.
It's like I'm reaching the max at 3.4, I'm going to try with more vcore or other settings but it's definitely not a good chip.
Do you guys have any recommandations?
EDIT : 3.4G 1.4875V not stable, and 3,456G 1.5V BSOD during boot
seems like it cannot even reach 3.4G... such a crap :(
Pacha, thanks for posting your results - they look pretty much in line with the L804A I tested earlier. I, too, could hardly stabilize it at 3.4GHz with 1.425v in BIOS (+ load line calibration enabled).
So when all 4 cores are fully loaded do you notice any major difference among their top temperatures? Mine showed about 2 - 3 C at most (@3.4GHz load), even though at idle the T difference was greater than that (don't know exactly why). If you see big gap in core temps you probably want to re-seat the heatsink. Otherwise it means the seating is already optimized.
And after you've done pursuing the top end, try to find the minimal Vcore that stabilizes the highest clock speed before the "Vcore big jump" kicks in. That would be the point where the CPU runs in the most efficient way (in terms of performance/watt). In my case, I found ~2.8GHz is that speed for the L804A. With a mere 1.175v the hottest core barely hits 47C while other cores < 45C, air-cooled. My guess is that better CPUs will have superior clock/voltage ratios for that point, which could be used as an index to illustrate a CPU's potential. Honestly, I'd use that optimal point as my 24/7 settings. ;)
You need to crank up your northbridge to at least 1.5v and your vtt to 1.4v I think your northbridge voltage is what is really holding you back. Mine is set at 1.55v in my bios. :eek:

So in fact it's even worse than I tought, because it's only stable at 3.3G with 1.46V!! what a :banana::banana::banana::banana: :down:
As temps are OK i'm going to let this one to 3.3 but with regrets, I'd have liked to pull 3.6G of it but it's a long way to go... :(
Why don't you try to pick another one instead of running at 2.8? That, is pretty low for a Q6600.
The point now is that apparently all the new Q6600 have 1.325V VID and are bad overclockers, so it'll be hard to find a good one to replace it.
I'm going to try 1.4V vFSB and NB but without any good expectation.Quote:

I've just made some new tests :
3393 (377*9) 1.425V 1.4V vFSB -> OCCT stops after 5 seconds
3393 (377*9) 1.425V 1.4V vFSB 1.4V vNB -> same result
3400 (425*8) 1.425V etc -> same result
I guess it's the upper limit...
Plus 3393 = 377*9, and 377 FSB is pretty low imo to require more than 1.35V, with my E6600 I had no trouble running 412 FSB with 1.35V, and I had the same result trying 425 coeff 8 instead of 377 coeff 9, so I don't think vNB is the problem here. Just that this chip is garbage unfortunately...
Pacha, my previous Q6600 had a VID of 1.325. To run it stable at 3.4Ghz (8x425) i needed 1.41v real for cpu and 1.56v real for NB. For 3.5Ghz i needed 1.51v real for cpu and 1.6v real for NB. I also had to increase FSB VTT some but dont remember how much exactly. My new Q6600 has a vid of 1.30. I need 1.39v real for cpu and 1.37v real for NB to run at 3.6GHZ (9x400).
I've got my Q6600, it's L745B108 batch, anyone heard something about it? Haven't got rest of my hardware yet so can't test it.
Mh interesting. Thank you for this remark, so maybe mine would need that too.Quote:

I don't catch very well why the quads need so much secondary voltages increase over dual, on my E6600 the vFSB didn't changed anything about stability, and I've seen other people reporting the same.
Maybe much more power drained and stronger signals are required on the FSB and so does the nb?
Btw, my MB capacitors whistle quite a lot while they didn't with my dual so I guess it's because this chip is a gas plant compared to the dual.
Unless you madely overclock your memory, you use +4Gb RAM or your FSB is above 450MHz, usually, you won't need to increase vNBQuote:

Many people still bump crazy voltages every where when they don't know what to do or what's holding them.
In your case, it is clearly the vcore limiting you. These L8x steppings act like B3 and early G0 chips. For a Q6600, I won't hesitate bumping 1.53v + loadline calibration if your temperature permits it. Intel specs are 1.50v, so with 10% margin on 65nm chips you can go to 1.65v. Usually, you'll be limited to 1.53-1.55 with heat
I never heard of any Kentsfield reported deaths at those voltages and I ran my B3 at 1.53v for few months too at 3.6GHz
edit: I noted you have a commando, it is a very bad overclocker of quadcores and stability near and above 400FSB is a random dream
My G0 Q6600 loses two cores every time I drop the multi to 8 and raise the FSB to 450 and over. It's been like this on both my P35-DQ6 and Maximus Rampage. I get four cores right back up when I switch back to 9 multi again. :confused:
It has been working just fine 9x419 for many months but could never get it to work under the same speed with 8 multi.
I am thinking my chip has a low FSB wall but is this the way all quads behave when they cannot sustain high FSB overclocks? They lose two cores temporarily? Seems a little odd to me.
I have a L804A248 with 1.325V VID. I have to admit its a bad clocker. Here are my stable settings:
3.08G (8x385) BIOS 1.25V, load 1.24V
3.20G (8x400) BIOS 1.30V, load 1.29V
3.30G (8x413) BIOS 1.40V, load 1.38V
Currently I'm running at 3.08G at 1.25V with temps around 60C load. My 2nd core is the hottest and 3rd is the lowest. Difference around 3-4C both idle and load. I find that upping MCH or VTT voltage doesn't help much in stability. Instead of failing OCCT or Prime, most of the time I will get blue screen if the CPU is not stable.
Does anyone have recent results with a Q6700 yet? I know it's an old model, but I remember a few saying they would try one since the prices have dropped. I'm also considering getting one as the 10x multi is very appealing. 400x10 sounds achievable on water :cool:.
So I re-checked my ambient temps and they are at 27c, so it isn't that far off with my idle setting at 40c. I have a new pump and the D-Tek fusion coming in which should drop my temps a few degrees. I do use my comp 24/7, but my temps rarely go above 55c even with the added voltage. I just don't use anything that pushes my system to the level that OCCT does, even video conversion and gaming don't exceed 55c. I am currently running some benches to see how much of an improvement the extra 220Mhz+ gives me. If I find it only gives me 5-10% more I may drop it back to 3.6Ghz, but we will see. I kinda like the sound of 3.8Ghz vs. 3.6Ghz, makes me feel like the investment is paying off. :DQuote:

Have you tried loosing your timinings to 5-5-5-15-60? I have no problem running at 1080Mhz when I am at 450x8. I can only run at 1021Mhz at 425x9 due to my memory wanting the 333Mhz strap. Anyway, you have some really good results with air cooling.
By the way, according to Eversest benchmark, I am at 9641 - 8192 - 8644 - 51.8 when I run at 1080Mhz, not too bad.
Anyway, keep posting your results,

whats the lowest vcore an average VID chip should be able to run ar stock 2.4 speeds? is 1.14 real pretty good?
so it appears with 1.325vid chips 3.6ghz is the max and requires 1.5Vcore maybe more. Ouch
I agree. But temps finally raise up if I set too much voltage and I'm not even sure I'll reach 3.5 with a lot of vcore, as adding 0.05V directly doesn't give me any more second of stability at 3.4.Quote:

Bought a brand new 2008 G0 Q6600 (which came in a dark blue box), FPO L806A692 with a VID of 1.325V :( It was a rubbish clocker and needed 1.45V to get 3.2Ghz OCCT stable.
But I found a G0 on Ebay FPO L730B292 and 1.2625V VID (which came in a LIGHT blue box). This one does 3.4GHz at default volts, perfectly stable:)
Needs 1.34V to do 3.6 Gz but maybe able to reduce that by tinkering with VTT and GTL reference voltages.

Did my first Overclock today and was pleased to find it stable. my Q6600 now running at 3.0ghz prime95 stable and 1h OCCT stable, Vcore: 1.168, Idle: 36, 36,34, 32c Load: 52, 52, 47, 45c.
Now that i have some time over the weekend
, ill try to push for 3.4 ghz.:)
Whats you're VID? sounds like you can push 3.6 on air at 1.4vQuote:

I would imagine with a higher vid you would need at least 1.45v or higher. My vid is 1.265v and I need 1.47v to be OCCT stable. Although the vid isn't the only thing to determine how high you can overclock it is usually a good indicator.

same here, 333 on the FSB, 3.06Ghz, stock cooler, idles at ~32, under load is high 40's.Quote:

I never thought that 4 cores could run this cool. My new Quad runs cooler at 3,6 Ghz than my 2160 did at 3,6 ghz without IHS. I had some trouble at first, getting a good OC but then I saw that I had LoadLine calibration disabled. When I enabled it, it became a complete different story.
3,0 Ghz was a of course a simple task, 3.4 too. At 3.6 I had to finetune some setting to get stable, I raised Fsb termination to 1.4 and vcore to 1.4. My coretemps didnt get over 70 with absolute full load at all 4 cores (S&M cpu (fpu). I started to play a little with 3.8 Ghz but had some trouble getting stable. I dont think this is going to be a problem, just need some more testing.
I absolutley Love this cpu, Q6600 still rules :yepp:
I think this chip is good for at least 3.8 ghz on air.
Maximus likes this cpu too. 480*6 ok, 490*6 needs more work. I dont know if thats considerd good on these chips, I´m :) anyway
Anything over 480mhz is good with the quads.
%75 2008 Q6600 all VİD > 1.3000v +

My L737B has a vid of 1.2125v , it is stable at 3200 with 1.2425v and 3600 at 1.3925v but I have been trying for days to get it even benchable at 4GHz . I achieved this today , I ran 3D06 at 4005MHz along with wprime 32 and 1024 but it took near 1.7v to do it and its only just stable enough for that . Temps were sizzling too , up to 86 while running 1024 so I wont be doing that too often. Thats with a lapped Fuzion , triple rad and IHS lapped too .
:(
nice results.Quote:

Now I just checked again just to make sure, and the VID value is all of a sudden 1.1625v, :shocked: which is almost to good to be true. As I said before, I didn now this valu coulde change. Second thougt, perhaps the first vid was somehow a leftover from my e2160, because the vid changed after I rebooted a couple of times.:confused:
in that case I´m the worlds most happy :)
About Batch, I dont now which number it is: L728A825 or E10342-00 or another?
Best vid I have ever seen.
This should be really pinned as a sticky. At least 3 posts a day with people claiming: MY GOD, I GOT THE BEST VID: 1.1xv
Sorry to be some :shrug: but I even noted that no one no longer bother to answer those people
VID we talk a bout is at default CPU speed, C1E and Speedstep/ESIT disabled and lowest is 1.20v :rolleyes:

NP :D, we all were noobs, we'll all be again noobs as technology changes so quickely. But there are so many posts these times with that VID misunderstanding :)Quote:

VID's starts with 1.20v and go UP... If you see less then that it's because you have power economy options enabled.
He he, Thats true.
btw my real vid is 1.3000.
Thats OK , I read many times over that VID is fixed , so I guess I was wrong too (VID as opposed to vcore) . My quad's VID is 1.2125v but its still an average overclocker at best.Quote:

That's is a good overclock and keeps it completely on the safe side. As far as running 1.45v, "Ha", I have ran my chip with 1.65v. Intel's white papers put the limit at 1.55v, so 1.45v is not a stretch. More than likely you would need to go to 1.47v or 1.48v to get the extra 10Mhz FSB speed. Whether it's worth the extra heat is up to you. Also, keep in mind that as soon as your chip goes under load you will get Vdroop unless your board has load line calibration or has been modified. Vdroop, drops your voltage down to prevent the voltage from jumping to high above the set voltage when you come off of load. My point is, although you are putting your voltage at 1.47v, in reality, under load it will be much less depending on your Vdroop.
At any rate, a 50% overclock is nothing to sneeze at, :D

Thanks:)
Yes you´re right. I rather run the cpu at 400 fsb at 1.425 than 410 at 1.475. I tried to get it stable at 410 1.475 but didnt succeed. I think it need closer to 1.5 for that fsb. Then I got 5-10 C more to handle..
But its always nice to see how high you can go. Its funny how you push the limit all the time. At first when you get a brand new cpu, its like, noo I dont wanna get over 1.45, after acouple of days, 1.5 is the absoulte limit, then 1.5250 and so on.:p: I haven gone over 1.6 anyway, with my 2160 since I dont have any water at the moment.
I just managed to bench at 4005 MHz , it seems quite a few can bench higher than that . Its not a poor overclocker , it requires much less voltage than my last q6600 but has topped out only about 70mhz better , so go figure.Quote:

.
Being able to bench it and running a stability test are two different things. I can get 4050Mhz to load and bench, but it won't pass an OCCT stability test. Don't get me wrong, its a great achievement to just be able to get the chip to boot to 4050, but see if it will pass OCCT or P95 stability tests and if it does you definitely have a gem.
Utnorris
Mine only posts at 4050 with 1.5 bios voltage, its a real hotty though, so even if it booted, it would be too hot to bench.Quote:

utnorris - what fans are you using on your rad and did you test with single fans ? How much difference did push-pull make ?
:up:
Those are San 1011's. I have a bunch laying around so I thought I would do a push/pull. After doing some reading, this seemed like the best way since I am running them at 5v so they are very quiet and I still get low temps. I was using Silenx which were very quiet, but in this configuration my temps are 10-12c cooler. Those fans are very efficient and if you read the latest fan test at the top of the "Liquid Cooling" thread, they have the best CFM and are highly recommended.
Utnorris
P.S. I may end up selling my extra's on here depending on whether I think people would want them.
I just bought three Scythe Ultra Kaze 2000rpm fans for my rad , they are a good balance of noise when turned down vs power when turned up , but still a bit noisey for me .

guys any comments on the Q6600 batch L723B837?
try pelase 9x multi. ;)Quote:

try :p:
Running my L804A900 G0 q6600 currently at 400x9 = 3.6ghz at 1.55vcore Bios set.
Idles at 30 on all cores, Full OCCT load is 49-49-50-50 degrees C with my apogee GTX
I haven't tweaked the volts or FSB much yet. I know I cna't boot past 3ghz with 400 strp. I'm currently on 266/677 strap 1000mhz memory.
Will tweak more and report final settings.
EDit:
Seems 3.6ghz is my max at 1.55vcore L804's suck
Is there a direct correlation between the VID of a processor and its overclocking capabilities; I ask because I just started OCing my new Q6600 and saw that my VID is 1.325. I know this is high in comparison to most others, but will it hurt me?
Mine is an L7 also, but it OC's piss poor or just my mobo is piss poor ( Abit IP35-E )
1.315v bios 3,2Ghz (400*8)
I am still a little new to OCing Intel and I was wondering why so many people are running a CPU mulitplier of 8. Is this just so you can gain a higher FSB, which will bring the ram closer to 1:1? I would appreciate any tips that you can provide as far as squeezing the last bit of OC from my CPU.
My setup is the following: Q6600, ASUS P5K-E, 2x2GB Mushkin Redline PC2-8000. I have already had the ram up to 1066 at stock volts and I am fairly confident that I can go past 1100+ with some voltage.
I'm currently doing 9x356=3.2Ghz. Vcore is 1.3V(1.28V idle, 1.29V load). All chipset and VDIMM voltages are at stock. RAM running at 4-4-4-12 1:1. My oc can pass 24hrs small fft and blend but will restart automatically after few hours with large fft. No bluescreen message unlike small fft/blend where i will get bluecreen if oc is unstable. What should I do to pass 24hrs large fft?
Hi,
I need a little help to buy a q6600 whit a decent VID.. I listen abouth the famous L737b.. but i don`t believe that they are available at this point .. or yes ?
or can yours advice me any other FPO whit a low VID...??
Thanks!!!
Yes there is.Quote:

My 1.21vid needs only 1.26v (in bios/ 1.28cpuz) to run 3600Mhz stable as rock Prime95 blend and 3dmarks (1200ddr2 Pl5).
But for over 4050Mhz they both pretty much maxed out the same with the lower vid needing less vcore then the higher vid cpu.
