beats me - but probably is for the LEDs... the hardest area of the module to remove the heatspreader from was that middle chip!Quote:

Just picked up a pair yesterday and after testing i think i got unlucky this time. No where near as good as my Ocz apha1000vx2 chips. Need 2.3 for 600mhz stable. My alpha chips stable at 2.25vdimm 650mhz. I needed to pull spreaders off and chill them with my flex xlc water blocks to work at 2.3vdimm\600mhz. With normal spreaders the sticks got very hot and needed 2.4 vdimm at 600. I think its got something to do with those damn led's but what do i know?. Was fun testing them anyways.
you mean the one from my review?Quote:

Tanks bro:D
Will be getting my Tracers this Tuesday (should have gotten them last Thursday, but the package came in empty), and this thread has got me pretty psyched. Was kinda skeptical about the LED's...but judging from the picture they look pretty nice. Nice OC's as well. Hope to get similar results as all of you.

Mine can 2.25V stable!Quote:

Tested the heatspreader module at default DDR2-1066Mhz 5-5-5-15 at 2.1v first to make sure it worked. And you guessed it, stripped it bare naked as well :D
As you can see the TIM is partially lifted off the ICs.. I tried holding it together to see if it will stick but it lifts off again by itself. So bye bye heatspreader :wavey:

So talk about bad QA, one module hs off center to left can't install in dimm slot, and second module hs TIM not making full contact!
I had same problem with heatspreader as you Eva. Prolly why cooling them with my flex blocks helped alot.Quote:

Looks like bare naked Micron D9GMH from Crucial Ballistix Tracer PC2-8500 are running more than fine @625mhz 5-5-5-15 3-30-3-3-8 at 2.1v vdimm!

Temp probe reading off ICs for Super Pi 32M run read idle = 28-32C and load = 32-35C with 92x38mm Sunon 120cfm fan on medium speed rheobus.
Ha I had the exact same problem too, it seemed that one single IC was about 0.2-0.5mm closer to the PCB than all the rest. Having taken off the heatspreader and used a straight edge there is a fair bit of variance between them all!Quote:

Looks like it's stable, maybe raised TRFC to 30 was the key? Given 2.2v is good enough for them to run at DDR2 1175 :)
Will confirm the result once again with Orthos by tomo, now I want to let it rest.

Those sticks are much better then mine Eva. Funny thing is that it did not help the overclock much but let me run with much less vdimm at 600 but not much more stable any higher with more volts.Quote:

It seems one side of the module's LED controller (middle square chip) is slightly taller in height than the other side's middle square chip meaning the HS lifts slightly off the ICs in the middle on either side of the LED controller chip. The heatspreader on that side is clearly at a slight angle like the picture here but not as bad.
Solution: No stripping of heatspreader necessary ?
Instead of stripping this module's heatspreader going to try another method, grab one of those strong paper clips, 2 pieces of cardboard and trusty hair dryer.
Place one piece of cardboard on either side of heatspreader, use the paper clip to clamp both sides of the heatspreader using the cardboard as protective layer to prevent scratching on the heatspreader. Now using hair dryer to heat up the heatspreader while leaving the heatspreader clamped down to making contact with ICs.
I'm hoping this heat and clamp method will allow the heatspreader to bend back inward towards the ICs to allow better contact :)
End Verdict:
The clamp and heat method seems to have worked, the heatspreader's TIM has made firm and full contact on the ICs and seems to have stayed for now. Guess have to wait until I get around to testing the 3rd and final kit :)
Eva... On my P5k deluxe would booting at 500fsb and clocking up help the overclock of these sticks? In the past i have booted at 499 and clocked up in windows. This is my stable overclock with these sticks and a pic of my ghetto rig lol:D
if the strap change exists @500FSB with your P5K DX bios then yes it might help get higher mem frequency clock.. same reason why you can clock mem higher on 5:6 and 5:8 dividers as that is on 1333FSB strap compared with 4:5 and 2:3 on 1067FSB strap IIRC
But you'd loose performance so would be better at <499FSB :)
Thanx Eva I will try.:up:
Here's my Tracer 8500's. Set at 2.1v they seem to be rock solid. Still playing around with them, I havn't had time to max them out or play with timeings any more. Will post more later.
those seem to be consistent results with these dimms. I personally like this memory better than any I've ever purchased. They are voltage friendly and they take numerous timings very well. I've found that mine like cas5 better than anything else. When I get my p5k I'll be able to finally see what these can do.
Later
I got 668.5mhz on a suicide run. Can't get anything over 595 stable though :(
eva2000, do you suggest running these things naked with a nice fan blowing on them? Also, any way to monitor their temps in windows?
Unfortunately there's nothing to read out mem temp in windows afaik.
If you mobo has a sensor input or you have a fan controller with a sensor hookup then you could put a sensor on the ram module and get your temp readins that way.
