Oh, and eva2000 is a ram tweaking expert, on any platform.

I know!

It's not so much the sinks themselves, being as thick as they are is actually a good thing as they can absorb more heat out of the IC's, it's the thick thermal tape they use that I think is the issue.

My Cellshock sinks are very thick also and they get very hot without good cooling.

My Cellshocks are GKX, my TG's are GMH.

After heating up the thermal tape and allowing them to set they work much better now. Even at a moderate 2.2v they get really warm now and give off a lot of heat. Seems they just needed to gel a bit.

I also tried some 4x1GB action with these (since I bought two kits) and was somewhat successful. I can get them up to 1155Mhz at 5-5-5-15 but they need damn near 2.45v which I don't feel comfortable running daily. Maybe it's just this motherboard but I'm surprised at how much voltage these sticks like. At 1280 5-5-5-15 and 2.5v I can feel this RAM wanting more juice.

hi guys i gotta question for ya i have 4x1gb ddr2 1300 team xtreems on a ud3r with a 9650, i can get to 4.5 stable with no issues(500mhz) im running 1:1 btw. Now if i try to get past 500, anywere from 500-600 i have to mess with performance levels and refresh cycle time just to get a post but locks before windows loads. it wont even make it into memtest at that speed and tough to get a post, am i missing a subtiming or two thats making this so tough? the best i could get it so far was a post and into windows (then freeze) at 525mhz was refresh at 59 and performance level 9, that will get me to the windows login screen but freezes. any info would be greatly appreciated im trying to hit 5g's or better. i have loosened the timings way up, didnt help, put volts to max, then min didnt help. i have added vcore and nb volts none seemed to make any differance.

sorry for asking in this post, but it seems that this group of guys are pretty familiar with this kit.

system:
ud3r gigabyte
q9650 @ 500mhz 4.5g, 1.4v in bios, 1.37v in cpuz, 1.36v at full load(cpuz)
4x1gb team xtreem ddr2 1300 @ 2.45v 5-4-4-13
single stage phase -52 @ idle, -48 @ full load

I don't think that the RAM is to be blamed in this case. This kit is one of the best OCing kits ever made.

So running a quad and 4GB of high-clocked memory can be a problem for the Northbridge, but since increasing the Vmch didn't get you any further, my bet is that you found the FSB-wall of your chip! 525MHz is a very good result for a quad already, maybe upping the tRFC to 60 will get you a bit further, but I don't think that will be more than maybe one MHz or two.

If you want to make absolutely sure that it's your processor limiting you, run only one stick in single-channel mode, CL5 and 1:1 and increase the FSB.

well i ran 1 stick @ 530 4-4-4-12 2.45v and did some screwing around with the subtimings and was able to boot into windows and run a superpi 1m bench at 9.8sec. didnt prime it or anything still tryin to get further.
