Could this be why my khx3200 suck?

[luihed]

I was curious to my my khx3200 that I got from RMA cant keep up with my other stick so I decided to open her up...... to my surprise, this thing has a thick a$$ thermal tape unlike my first stick which was assembled in the USA..... WTF was Kingston thinking?...... this :banana::banana::banana::banana::banana: will make the ramchip heat up instead of cooling it, anyways I just ordered some coolermaster ramsinks and hopefully that will help overclock this stick to where I expect it of even more...... take a look.....

Odd indeed....

I have never looked under the headspreader on mine, maybe i'll take a look now.

[speedstream5621]

That's why I always laugh when I hear people talking about how good heatspreaders on RAM are. They don't make contact with all of the chips most of the time and are far inferior to just to having a fan blowing on them.

Looks like yours wasn't making very good contact with the "thermal" pad by the looks of the first pic.

[luihed]

Youre right, more than half the ramchips werent making contact...... these modules were assembled in china and the ones I have from the USA didnt have the thermal pads......

[Soulburner]

How do you get this damn infernal heatspreader off?

Kingston has these things on good....

[luihed]

Just take a peek on the side of the sticks..... you should be able to see though if there's no thermal pad in there..... does your stich have that red emblem on the heatspreaders?

The Red head guy? Yeah he's there on the left side.

Says Kingston right under him.

These should be the same ones climbski has since we ordered from the same batch from newegg. His clock fine afaik....

The white label on the right says ASSY IN USA though.

[Lemina]

Very interesting find Luihed. Tell us how they perform with better contact.

[luihed]

With the heatspreader on the best she will do is 233fsb at 3v...... now that shes naked and all cleaned up, shes at 245fsb at the same voltage:D it even beats out my good ram by 1 fsb.......... smartfanII is blowing right at it though......

Im gonna get some remsinks tommorrow and see it that helps...... maybe I have a 300fsb stick here and I didnt even know about it lol........

[Soulburner]

Wow...was your "good stick" run with the heatspreader on or off?

If I can get that kind of a gain by taking mine off....they're coming off NOW! :D

[wierdAl]

so do you have bh5 or ch5?:D

BH5.

CH5? Pfft....we don't deal with that stuff :D.

[luihed]

It has bh-5s.........

my good stick still has the heatspreaders but looking from the side, it doesnt have any pads at all so Im not gonna touch that one...... shes pretty good the way she is:D

[esoteradactyl]

i just got some from newegg and they were also assembled in china. looks like mine have the thermal pad also. im having problems getting them over 240mhz with 3.6v. they will boot up to 259mhz but there only stable at 240.

[hatemi]

My old KHX 3500s also has got that 2mm thick tape inside them but the contact must be better with it cos the heatspredders get damn hot at 3.2v:D there is somethin flaky with them cos they memtest nicely at 245FSB solo, but when usin DC they arent stable even at 230! any ideas what might be causing this?

Way to go! :D

[Fewture]

I have my spreaders off for as long as I have my HyperX CH-5.. they do 249max @ 11-2-2-2 @ 3.25V and 245 pifast.. Imo all heatspreaders are bad. All of them have the tape..

Try doing that on an Intel system.

That's why I don't mess with CH5...

Yep, but the mem is fine ;) My Corsair 3200LL Twinx also did 11-2-2-2 and that was CH-5 too only those hit the wall @ 240MHz.

Anyway, my Corsair got pretty hot w/ the heatspreaders on so I took them off. The mem was cooler and ran a bit faster (not 12MHz though). After that I got the KHX and it had the same crap on it so took that off straight away. On the Corsair as well as the KHX some chips weren't touching. It is complete BS those hs :D Just pull them off and putt a fan on them..much better ;)

[Soulburner]

I had the same Corsair and they would also hit the wall at 240 but with slack timings and would fail to boot with the 5:4 divider which severely limited my overclock by 300mhz.

[skate2snow]

CH5 is not that bad!! i tryed some OCZ 3500 CH5(from a bad command, thats why i dont have my KHXPC3500) and it was perfoming as well as my friend |V|II

Wow, that is a nice gain in fsb just by removing the heatspreaders!:eek: Have you tried more voltage?:devil:

[luihed]

Im gonna put some ramsinks on it and see what she does on 4v....... I really wanna hit that 300fsb mark.....

[esoteradactyl]

well i had success with taking the spreaders off. they run 500mhz with 3.6v stable. i also noticed my balck level II has the exact same crap on them.

[luihed]

Cool meng...... They feel like brand new rams after the mod.......

[kleptophobiac]

don't you void the warranty when you take them off?

How would you put them back on? :twisted:

Maybe this is why my sticks get worse as voltage goes up....

You void the warrenty when you raise voltage too. Doesn't stop many people though.

how do they know if youve raised it though? seems like putting something on there would be more costly then not exepting 4 rma's a week.


ive got some khx3000...i think it has the pad...from the chips to the heatspreader theres this grayish pad like in luihed's pic

what do you guys think about putting some ocz ultra II or as3 on the heatspreader and mounting a case fan over em? I think that would be the best option over leaving the heatspreader off w/ the fan...plus it looks like crap ass value crap without the heatspreader. Im guessing 242ish out of this stuff with 3.3vdimm. Dont know if my mobo will go there though...although ive seen reviews with it go to 240ish. Btw ive heard this ram is bh-6...whats the difference to bh-5? I believe just bh5 hits higher speeds w/ lesss voltage or something?

[Speed_Mechanic]

Using thin-finned TSOP-sized heatsinks with direct air-flow over them would be more then adequete for most overclocking situations. Attach the heatsinks using either thermal epoxy or a thermal compound (Arctic Ceramique recommended) w/ some adhesive. Then make sure there's good airflow over the heatsinks.

[Kobalt]

do i need some "sticky" compound? afaik it clips on there...

asC is not epoxy type is it?

I was referring to useing heatsinks directly on each TSOP chip and not the use of a heatspreader.

I keep them in a CD case.. Pull the inside out of the case and they will fit right in. You can putt the hs back anytime.

[kleptophobiac]

Well, I took them off and didn't see any FSB gains. Oh well...

[enroscado]

Some feedback:
I took the heat spreaders off my Corsair 3200LL v 1.1 (BH-5), but didn't notice any gain at all. :(

A question tho'.

http://www.losvagos.net/SS/HARD/wathsthat.jpg

See the picture? I made a circle pointing at some little things, what are those?? Because 4 of those fell of while i was taking the heat spreaders off, and i thought i had screwed it up, but the stick is still working fine.

[luihed]

I just bought 8 of these babies ...... my rams feels like it weights 5lbs lol.........

any increase in overclock? keep us posted.

[speedstream5621]

Does anyone have any temp comparisons of different voltages on RAM without any heatsinks or fans blowing on them?

I find this whole heatspreader thing hillarious, some of you guys got some SUBSTANTIAL gains from removing it altogether.:YIPPIE:

Well, if you look at the tape it's not that strange actually. Mushkin also uses the stuff.

I can actually feel difference in heat. When I feel the chips now they are not hot at all. With the hs the whole hs got pretty warm.

I just noticed that on my mushkin as well. After reading this thread, it made me wonder if the heatspreaders were making good contact with the ram chips. Most made good contact, but some of them didn't.:mad: I also noticed some thermal padding underneath the spreader. Those things are coming off as soon as I get a hold of some ramsinks.

[kleptophobiac]

Nice avatar there Lemina!

By taking off the heatspreader, my RAM seems to be responding better to more voltage! Yay!

[speedstream5621]

Probably because its no longer overheating.:)

Surface mount capacitors, IIRC.

Please give me some more info:

Why my RAM is still working?
Will something happen in the long run?

Thanks!

[eshbach]

ok, i have hyperx 3500 and i really want to try this, but i can't figure out how to get the hs off without breaking the metal clips at the top... advice please...?

[kleptophobiac]

little tiny screw driver, poke in the top of the metal casing where the clamshell comes together at the edge of the clip... pry the clip up.

simple!

[hatemi]

It really helpped! Now my KHX3500 have run prime just fine with street racer anabled @235:D might have to try upping the FSB later;)

AFAIK, LL is strictly BH-5. :confused: :stick:

[eshbach]

ok, i found a screwdriver small enough and did it. still totally bound by the FSB (233mhz tops) but now i can do it on 2.77vdimm! looks good for when my shuttle board gets here and i drop these in my A64.

All depends on which revision you get.

Depends on what they are there for.

They could be installed to be able to release a small electrical charge really darn fast (memory needs it when it needs it..) or they could be acting as pull downs like on the Radeon 9500np -> 9700/pro hardmod.

[enzoR]

luihed, have you tried them with 4 volts already?

Am I right in thinking the Rev 1.1 was the stuff carrying BH-5?

I'm trying to track some down as I type. :D

It looks like it might be worth pulling the heatspreaders off this OCZ before I spend any more cash though.

[luihed]

Originally posted by enzoR

For some reason, it wont boot past 3.8v....... Ive never tried giving that much voltage with the heatspreaders on so im not sure if its because of taking off the rams or something else.......
