GeIL 2GB (2x1GB) PC2-6400C4 800MHz ULL

To get near 1000Mhz you'll need to slacken the timings, as far as I'm aware they use Elpida chips which are not the best for 1000Mhz the Ballistix are much more likely to do the job as they use Micron chips.
 
I've got 4gb of the GeIL stuff and have it running at 1066mhz 5-5-5-15 2.3v, left memtest going for 7hours and got 0 errors and haven't noticed any stability issues in general yet (although I'll admit I haven't gotten around to putting it under a lot of stress lately)

Now that's the sort of thing that's worth listening to, so much talk but hard facts and figures are what you can use and rely on.
 
What's best slacker timings or higher FSB? Also what's the max DDR2 V you are putting through this ram. Mine are running @ 4,4,4,12, 1:1, 2.1v @ 756, if I go above 800Mhz I can't get into windows with those settings. Should I bump the DDR2 v or slacken the timings if I want to get a minimum 800Mhz FSB. (Actually with my cpu overclock I would be looking at 850Mhz, 8 x 425 giving me my present overclock of 3.4Ghz).
 
Well the ram is rated to run at 4-4-4-12 800mhz so if you can't hit that then you may have a problem with your ram? The highest V for the GeIL ULL RAM is 2.3V.

And although I'm not too sure because I'm still fairly new to all this overclocking stuff I believe that higher FSB is better than low timings to an extent, obviously not if you take it to an extreme.

I've got 4 sticks of the Geil ULL RAM running at 800MHz 5-5-5-18 but windows just doesn't wanna boot with it. It works fine with just 3 sticks. Do I just need to crank the RAM volltage up???

Do all 4 sticks boot up at stock settings?

Check your Bios settings and enter the timings and recommended voltage manually first of all.

memtest the modules at stock timings before over clocking the modules

900MHz here on 5-5-5-15, have tried to go higher with it but think i may have to slacken the timings even more to get there, this is on 2.1v. Could give it a go up to 2.3v i suppose, but will be getting rid of the 6300 and Geil for a q6600 and Ballistix 6400 RAM, so hopefully will have more joy there.
Quick questiong, with the Q6600, are all *** chips being sold now the G0 stepping or are they still selling the non G0 as well?

The Q6600 presently being sold by OCUK are GO stepping. The B3 stepping is no longer listed/ available. The dual cores i believe are MO revisions

The ram you presently have will serve you well combined with a Q6600.

The clocks you have achieved with the Geil ram are good. Why the need to change over to the Ballistix? You will still achieve excellent over clocking with both the Q6600 and Geil memory.

I am getting the CPU through work, and the account they have is with a competitor, not OCUK. Due to this, it looks like they dont have the G0 stepping, just the normal one, may have to try and twist their arm to buy from OCUK to go for the G0, cos would like a good springboard for overclocking it.
If i did end up goin for the the non-G0, would there be a massive difference in max overclock or would it be temperature held back?

Technically the B3 (130w) runs a lot hotter than the GO (95w). As temperature increases' due to upping voltages to increase and stabilize the overclock.

So technically yes there is a huge difference between the two when the heat/ temperature of either chip is taken into consideration which will affect the over all clocking headroom of either chip. The GO chip would be a more effective purchase over the B3 especially with the intention to overclock

May have to have a word then. On the competitor the MFR# is BX80562Q6600 and the thermal design power is described as 105W on the 65nm. Presume this still indicates the non-G0?

They're all set to stock settings and i've run memtest on each of them seperatly and no errors are shown. It's just when I put them all in together.

I've even tried upping the voltage to 2.3v which is the max for my RAM and I still get blue screens when I get into windows!

Did you clear the CMOS? before reinstalling the modules?

Clear CMOS put modules in to dimm slots' 4 and 2 boot up enter Bios and re-set voltages and timings. Boot in to windows, power down add the next two modules.

Lets see if this resolves the problem

(when you ran memtest on the modules separately did you use the same dimm slot for testing the modules?)

i have the 2 gig of geil with E6300 chip multi locked to 6 or 7 - it has these selectable only.

i tried to overclock my geil on a P35C DS3R giga board and it don;t seem to work as shuts down, re-boots, then shuts down and comes up normal. How did you get you chip o/c'd above 1.86 mhz? i will change in a few mths to quad core but can't afford to yet.

is another 2gig of geil ull 800 mhz ram worth purchasing? vista 32 bit ultimate i run.
