no. QX9650 and QX9770 can have higher ones.Quote:

note the diff. volt with same speed
my process. pass stable test my frind process. iam not sure
OC the CPU and you'll find out. My QX9650 vid 1.25V and QX9770 vid 1.275V reached 4 GHz at 1.38V, so quite pathetic. Out of two Xeons X3350 (equivalent of Q9450) I've had the one wih vid 1.2V overclocked worse than the one with vid 1.2375V, so higher vid is not always an indicator of worse OC potential.Quote:

Qx work fine Loser777, up to 4.5Ghz... some need 1.45 volts, some need 1.55 for that... but I would never run my Qx at those volts daily... I keep mine at 4ghz daily... only for benching and co I go up...
Got an 814 with a 1.325 VID, won't Prime 3600 even with 8x multi and 1.504v (as reported in CPU-Z after vdroop). Temps in the mid 60's on a DK P35-T2RS (I know, not the best for Quads but I'm not looking to do 3800-4000). Tried all kinds of vtt, pll, gtl, mch combos. It needs just under 1.4v to pass Linpack at 3400. Seems all right at that speed, but I'm kinda wishing I went with the E8400.
I honestly feel better about my setup after reading this. I am deeply sorry for peeps with bad chips/. I will sell mine to some one here when I decide to get an E8600. My VID on the Q9450 is high BTW 1.225v.
quit buying high VID chips i mean,, how many bad purchases does it take to learn
interesting little twist.
RMClock will actually change the default VID in coretemp when using RMClock to lock the multi and vcore.
try it out,, you'll see.
now unfortuantely i have only used this on dell systems and dell systems, unfortunately do not have overclocking options and only a select few boards allow setfsb to change the fsb, but because of no vdimm control you cant change the fsb very much without taking the ram out of spec.
either way someone should give it a try and see what happens.
Mine has a high VID and I'm happy as can be with mine so, that doen't hold up like Leophold said.Quote:

Sorry for rubbing it in:p:
@ Truehighroller & gallag: I'm curious, did you guys get yours in the retail box or OEM/tray? I'm actually counting blessings because I read some threads about the earlier 804's brick walling at around 3200. That would be the equivalent of one of my previous bad luck chips, when I missed a good batch by one week in the Opteron 165 craze; my week 51 took work and high voltage just to hit 2750 whereas week 50's were dancing around 2900-3000+ near default voltage).
@ Lestat, personally I went into it hoping for what I saw as an average lately of 3.6GHz with about 1.45v, I would've been okay with that during Winter. Ah well. Trying for 3500 :p:
I got mine in retail boxQuote:

At stock speed I can hit 3.6Ghz with no issues
But to get to 4Ghz stable I need much more juice...like 1.4v which is quite high for wolfdales....bad chip:down:
All of my Wolfies have been 1.225 VID but they have all clocked differently...my Current E3110 is 1.225VID but does 4.4ghz at 1.46V
My E6750 is 1.35vid but it does 3.2 at 1.365v and its at 3.6ghz now with 1.375v.The highest i have had is 4ghz at 1.5625v.I dont know if there is a lower vid E6750 though,but 1.35vid does seem pretty high.
My old Q6600 had a VID of 1.325 and it topped out at 3.4GHz no matter what I threw at it.
My E6750's VID was 1.3125v for 2.66Ghz, in the end it took 1.56v to get it to boot and run at 4.2Ghz but I never did get it 100% stress test stable. Conked out after a few hours... 4GHz was rock solid after I changed to a 266 strap and brought the v's down though.
I've got an E8600 now with a VID of 1.2500v for 3.33Ghz and it runs 4Ghz on 1.192v 100% stress test stable :rofl:
I'd love to take it further but this rampage BIOS is a dog and 408 doesn't seem to be any better. Constantly get detect RAM errors all over the place. Thought it was the RAM but flashed back to 308 with my E6750 for a quick test and old settings work fine with stress tests etc. So just a bad BIOS tbh :shake:

I would post but well I may get stoned :)Quote:

It does seem to be a general trend that the lower VID chips run hotter.
My e8400 has a VID of 1.225v and it does 4005 MHz stable at 1.32v load. I haven't pushed it higher yet but I will be staying under the max of 1.3625v so I doubt there is much left in it.
My Q6600, I don't know what the VID was but, I had it in an overclocking contest and it did 4.135Ghz~ on air at 1.6v. I bought both of my chips retail once the price droppped on them. My 9450 is a 813.
I have a q6600 G0 which will OC at max to 3.6ghz with a vid of 1.3250. I cant rember the voltage I had it at but I think I had it @ 1.475v with the CPU watercooled nothing else in my watercooling loop. The CPU hit 65 celcius under full load. I could boot to post " 4ghz but failed to load windows. Can load windows @ 3.8ghz but it will crash as soon as I try running any programs. The best stable I can get it to is 3.6ghz.
I am getting an Asus Maxus Formula soon and as soon as I change the CPU water block Ill be reinstalling my Q6600. Will do some testing.
Thanks, supports the theory that Intel scrapes the silicon for the OEM Q6600's from the proverbial "bottom of the barrel." Mine was OEM, figured there was no diff, didn't need the heatsink nor warranty :brick:Quote:

my q9550 has a vid of 1,2375v. but i have no idea whether it's good or not, lol.
