I see a lot of variation in the VID's on these chips (or is it that people aren't using the latest Coretemp?)
Mine is 1.25 which seems very common but several posted here are in the 1.1 range. That seems like a pretty big variance.
Also, I haven't gotten around to going above 4 ghz yet but my load temps don't exceed 38/39C after hours of orthos (1.232 in windows). thats with a lapped TRUE with my fan on it set to 1000 RPM with case ambient temps in the 24-25C range.
Robilar I have the same batch as you. (Canada Computers, by any chance? :) )
So far, I've been able to get it to Linpack stable for 5 runs on IntelBurnTest at 4.3GHz on 1.36v on my Maximus/Rampage Formula. What are you getting out of the chip so far on the real X48?
It also looks like mine has stuck sensors. 40*C and they won't go any lower. They don't start to move until I put the chip under load. Should I return it and get another one?
Yes CC :)
Mine don't have stuck sensors at all (I was quite pleased as my QX9650 was a mess)
I just started runs on the chip. now that 4 ghz is out of the way, I'm going to start moving it up.
Damn :(Quote:

I'll have to see how good of a chip it is before I do that though!
bought from neweggQuote:

I bought my E8600 guys from NCIX.com ....... hopes it a good one ..... it be in tomorrow to me ... i hope.
I was going to go with Canada Computers, but we pay both taxes then.
Mines a Canada Computers chip, Q820A596 :up:
Same batch as me...Quote:

Another Q822A435 - VID = 1.1875
IHS is warped pretty bad so really needs lapping, but I guess voiding warranty should be worth it.. (!?)
Quick test:

i'd wait a bit before you lap itQuote:

nope, very pleased with the chip so far.Quote:

I'm crossing fingers for 5.0GHz @ 1.35/ 1.375 :D
Wow...4800 on your M2F?Quote:

Hmmm..time to make a call to CC, I think.
gtl's will play a big part in settling the chip down, so will pllQuote:

still like my quad better:D
On my RF 0408 bios I'm using:
CPUPLL: 1.52v
CPU GTL Reference : 0.67X
North Bridge GTL Reference : 0.67X
try 63x for cpu
whats your FSBT at?
FSBT = 1.24v (bios)Quote:

Anyone know Q820A324 batch with 1.25VID?
I can't reach 600 fsb over p5q3 dl :s
61-64% glt no moreQuote:

What are you clocked @ with that batch.. ? i may have access to same one.Quote:

464x9.5 same GTL and same vcore...same result.
I bumped vcore up to 1.45 and still get the BSOD.
So either I get no scaling after 4.3GHz with 1.36v, or there's some settings I need to tweak more. I can't get another 100MHz out of this bad boy...
Try loosening your timings and or mhz on memory.Quote:

GTL's 61-64 i read somewhere.
1.36v is max i would ever do.
And damn it my freaking E8600 CPU never arrived today .. they telling me tomorrow now.
Buggers.... but now i am getting the gut feeling of WHY did i by it .. if sensors are screwy on so many.
I just pray its a good batch and good IHS and good sensors and good OC'er ... wow thats a lot to pray for .. i am praying for it.... :)
Right now 4.0Ghz with 1.23vcore in biosQuote:

I'm trying to boot at 600x7 but i can't .... i have try few things but all things didn't work :s
My RAM is good at those speeds. I've run it at a higher speed with a higher FSB and it does Prime Blend, mt201 and Linpack no problem.Quote:
