24 Kits of Corsair PC 8000 UL at Newegg.

why is memory still so expensive? weren't like half the manufacturers found guilty of price fixing?

No, they dropped prices to help kill rambus. That was like 5 years ago.

DDR2 is expensive becasue AMD is now DDR2 and intel finnally has a CPU worth buying.

Combine those two factors and the DDR2 demand has skyrocketed.

My Results.

4 x 512 meg.
2.4 volts daily. 1000 mhz, cas 4-3-3-8.

ram tops out at just under 1.1 ghz.
does not like voltages past 2.67 volts, but with these results, does it matter?
all I wanted was a ras to cas 3 ram stable at 1 ghz, without crazy voltages, and thats what I ended up with, so no regrets here.

the ram in 1 gig set up, both sets top out at about 1.12 ghz.

cannot run cas 4-3-2 at 1 ghz, without errors.
this ram is close, but not as good as my 5400UL, which can do cas 4-3-2 without errors all the way to 1070 mhz.
so while this UL 8000 seems extremely good, it doesn't beat my 5400UL v.1.2 but then again, I really didnt expect it to, when running twice as much ram.

My one pair is doing well.....so-so.....Toped at 2.65Vdimm....
My other pair is a WINNER.......It can handle up to 2.75Volts error free....
One module - as it was - could do 420MHz error free (and I'm talking about Cas 3-2-2-1) and the other one up to 415MHz....
After my mods on them, now I can bench up to 434MHz with Cas 3-2-2-1 and VERY tight sub-timmings and 3D bench up to 427MHz.....Well I'm OK with this since they passed my Crucial which can do 417MHz 3-2-2-1 for 3D.....

Thanks a LOT movieman.....

nice rams.. show us some results..

"Photo mod resaults" for the time been.....

Man they sold out fast.....

Did you lap the spreaders and put sinks on them? What about the cheap stock TIM under the spreaders?

My method is since BH-6's time.......Take a look at my Crucial PC6400 Fatbodies.....The same thing followed for the Corsairs too.....


















Sorry for those many photos but I just wanted to be more detailed in case that someone who sees them to understand what to do (if he wants to do the same)....

My pleasure. Was nice to be able to help you after all the knowledge you've shared here.

Interesting... The cooling mods help clocks that much? What are the soldered wires for, holding it on? Why not spread the TIM before applying the spreader?

Looks like I'm gonna have to do some volt mods. My vdimm is limited to 2.4v and that's not enough. (P4WDH)
Your ram is looking good. What mobo are you running your corsair on?

Look......When I took them and put them on my mobo, one of them could do 420MHz error-free in memtest.....Though it was ONLY for one loop MAX cuz it was getting hot from the Voltage.....After the Mods I could do as you read on the photo on each of them for much time.....

The cheap stock TIM under the spreaders as you said does nothing at all.....It's a joke.....A BIG joke......It just CAN'T absorbe the heating from the chip and spread it to the heatspreader.....
You touch the default heatspreaders and they barely warm....AFTER the mods, go and touch the new copper heatspreaders to see if they're hot or not....You'll be surprised.....
ON the cooper heatspreaders now, we apply a lot of sillicone paste too and around it we apply fast glue...We place the Aluminum heatsinks on the copper heatspreaders and we press much until they are glued on the heatspreaders.....
Doing so we gain TWO things:
a. With the cooper heastspreaders, we absorve the maximum heat from the chips and
b. with the aluminum heatsinks this heat goes away fast PLUS we can keep our rams in a LOW temp for ever, by adding a fan over them.....
So from 420MHz and one loop error-free we go to 435MHz for much time error-free.....

No the "wires" actually are thick and their puprose is to SEAL the chips from RF by grounding the heatspreaders.....They are soldered on the heatspreaders and afterwards, on the Ram's PCB as well (it's ground).
Now the chips are "alone" and they don't archive radiation from any other components near them so as to be "confused" somehow.....

Q: "Why not spread the TIM before applying the spreader?"
A: Because it's not only TIM that is applied on the chips....After we have applied the TIM (I call it sillicone paste) , we apply fast glue around the TIM (upper corner and down corner)......After we have applied the TIM and the fast glue we HAVE to PRESS the heatspreader on the module so as to be glued.....By doing this, the TIM also spreads around the chips and the heatspreader.....
We must be carefull though when we press it so as to be "straight" with the PCB cuz if it glues, it's difficult to remove it afterwards (it needs heat around 80 - 100*C )

Ha, ha, ha......we made the topic for moding the ram modules....


EDIT
BEWARE to apply a lot of sillicone paste ON the SPD chip too, cuz when we play with high voltages, THIS is the one that can't handle them firstly and then the ram chips......So we HAVE to cool it too.....

Now I'm with ABIT AW9D-MAX......

best tangent i have seen a thread take in a while

thanx for sharing the ins and outs of your superior RAM modifying skills Hipro, much appreciated by more than just myself i'm sure.

wow... Time to switch cooling on my ballistix

No the "wires" actually are thick and their puprose is to SEAL the chips from RF by grounding the heatspreaders

Is that important or just some insane precaution?

And one last question, hope you don't mind. Why not just epoxy large heatsinks on each ram IC?

No individual heatsinks on each ram chip cuz we will lose the "sealing" of the whole module.....and YES, nowadays we NEED sealing cuz we have to deal with 500, 600, 700MHz+ and not with 33MHz that it was in the past....500MHz transmiting is about 15 times more than 33MHz....
Companies haven't given the right precaution on this.....They just keep sealing the PCBs but not what's outside of them, which - actually - it's the one that transmits.....

You're welcome....

just a heads up, there is some more in stock. i just checked and they are showing 7 available. best of luck for those that missed out first time around...this canuck needs a PO box in Port Huron i think

I picked up two sets.....LOL

[[XC] DragonOrta]

Just picked one up. There's 4 left.

[The Nemesis]

Is 4-3-3-8 that much faster than 4-4-4-8? I've got two 2gb kits that run 4-4-4-8 DDR2-1000 @2.2v. Just askings cuz Kunaak's results were 4-3-3-8 @ 2.4v so that seems best to hope for.

[wtkprol]

2 left. Are these any better than this TeamGroup ram right here. http://www.tankguys.biz/ddr2-44410-8...edf9e9f9515b15

Because I can get both for the same price?

[[XC] DragonOrta]

They also had one stick of 5400UL for $59.99 that I snagged just to see if it is in fact D9 fatty.

And the 8000UL is all gone.

[charlie]

and gone
