I just got my 8 gigs of this stuff in my system and seem to be having similar issues to yours. At 500MHz FSB on an Asus p5q se/r I need to put 2.2V through them to get them to pass memtest without errors. This is with the latest BIOS.
It always makes me a bit nervous to volt over spec. I will test this a bit more and let you know what I find.
I'll be interested to see how you fair with yours. Mine did 515 fsb on x48, which is the highest I tried them. I believe that took a tad over 2.1v as well.

I got 8gb too, last night I was trying 7x500 but very unstable.
5-5-15-55
ST RD Disable
the other RD option disable
Mem OC Charger Enabled
AI Twister = Lighter
NB = 1,32V
NB GLT = 0.600
Mem 1.98V, I heard P5Q have a + .10V in memory, so 1.98V gives 2.08V if a increase to 2.00V it freezes when trying to run any 3D aplication.
And some of you are posting with more than 2.10V I donīt get it
I have another rig with 2 pair of this ram on an Asus P5K board, 8GB @5-5-5-15 2T 2.1v 500Mhz, running with zero problems, it could easily go higher...
My 2.1v is measured on my board, the actual bios setting for 2.1v= 2.0v.I got 8gb too, last night I was trying 7x500 but very unstable.

Are you guys using 1:1 ? or other divider for the memory ?
My original ideia was getting this memory for trying 8x500 or if lucky 8,5x500.
I use dividers, 1:1 gives no performance advantages...
I am running 1:1.
Also, I have no idea what the "real" voltage is I am sending to these modules because I can't seem to find out how to monitor vdimm on the P5Q SE/R. This board is kind of 'eh'. You can't set voltage to the hundredth on this thing.
The only memtest stable setting I have found so far is MANUAL 5-5-5-15 2.2v with ALL of the remaining memory settings on AUTO. This includes the Static Read Control/OC Charger, ETC.
Again I have no active cooling on these modules and am nervous about volting them over spec.
It looks like you have too many settings configured to isolate this to only the memory. Take the processor out of the equation! I would try to set as many settings to AUTO in the BIOS as possible, run on a 6 multiplier and boot into a memtest.I got 8gb too, last night I was trying 7x500 but very unstable.

Try setting tRFC from 55 to AUTO on your board. Try running with 2.1v all other memory settings to AUTO with the exception of 5-5-5-15
...by the way, I just purchased these from newegg and received '840' (2008 Week 40) from the Whittier CA warehouse.
I will try that, I wasnt to worried about cpu clock since I was already running at 4.132Mhz with my old 4GB kit.

I'm glad you found somebody else to bother
Using memory options on AUTO besides Vmem may work well in this particular board indeed.

Wow...
These are only $68 on Newegg now.
I envy Americans, but I always wondered why the economy over there is breaking
Over here they are Ģ58 (around $115).
Back when I got my OCZ Flex II, they cost Ģ76 and mine were, and still are Ģ99.

Nops, not working, setting 500 and everything else as the manual said, freezes during boot, a littlejuice on the NB help to boot, but its unstable.
Tried 2.0V, 2.02V, 2.04V, unstable, 2.08V freeze.
9,5x333 and memory set do 1002, 500:500
I dont know if there is much more to change in the bios to make this work, tomorrow I'll try 4GB just to confirm that its a memory problem and not a NB issue.
Right now is running at 490Mhz 1:1 with 6x multiplier, and so far its working.
EDIT:
Houston we have a problem, 490 is a no go.
Just so you know, with 8GB I am running these at 2.2v. 1.3v NB @ 500MHz FSB. I emailed tech support from G.Skill and they said running 2.2v through these modules was fine. Memtest ran 10 hours no errors.

EDIT: What the tech said was that my motherboard *might* be under-volting the memory a little and that if they work at 2.2v it would be fine to leave them there. I honestly am fine with this seeing as they have a lifetime warranty and I replace my components every couple years. YMMV

I couldn't get my pair to get to 500 FSB either 1:1.
In my experience, these sticks will work fine at 2.1 real voltage. I have to set it to 2.15 in BIOS though.
Having said that, I've noticed that when overlocking with 8GB of RAM, one needs to give their board a lot of voltage. Although, even with 1.6 on the NB I wasn't able to get 500FSB stable. I'm starting over again from scratch, because being an idiot I didn't write down my stable settings.
Heh. My 4gb kit need 1.98v for 480fsb, 2.04v for 482fsb and 2.06v for 484fsb on my board! How weird is that?

Hi
I don't push my PQ's to 1066Mhz trfc 60 5-5-5-18, i'm tryied with 2.1v and the result is the same, BSOD in vista.
Only at max. 1033MHz 5-5-5-15 trfc 55 are stable with 2.1v.
please help me.
My hardware: q6600, 2x2gb gskill pq pc8000, asus p5q deluxe bios 1406, msi 8800gts g92 oc, ocz sxs 600w.
Thanks.
(sorry for my bad english)
Bump!!!!!!!!!
Well, considering the RAM is only rated to run at 1000Mhz, it's not surprising they wont go over 1066. Be thankful that you got 1033.Bump!!!!!!!!!
If you wanna get higher, raise the vDIMM
Add a 120mm fan to cool the sticks and raise the juice up a little to see if that helps.
My PQs are with a 2x80mm fans, i tryied with 2.2v and the result is the same, BSOD after 7-8 hours, why the others PQ's of this thread make the 1100Mhz with only 1.9-2.1v?, my pq's are a bad ocers or with bad settings?
(sorry for my bad english)
Okay....
Is there a difference in the divider between 400/800 and 333/667? Because, to me, logically, they are both 1:1. However, when changed from 400/800 to 333/667 and I can now get my tRD value to 8. If I change the tRD value to 8 when I use 400/800 my computer crashes. I'm confused.
Yes, there is difference between the different straps and what the tRD can be set to for each. Anandtech's article is a good read in that respect.
Yeah, but isn't the strap 1:1 for each?
