Today, I got my hands on a Thermalright HR-07. The firs thing that popped into my mind when the HR-07 was released was whether these heatsinks would bring significant improvement to my RAM's performance. It was a tough debate because all the great overclockers dont believe in these kind of things because they pose to be eye candy and such. Well, today i stand before you to show you who is right and wrong you can be the judge here

Thermalright HR-07 DUO
Lets start with a quote off the website

HR-07 Duo a much better improvement on this particular issue. Now you can install as many memory modules as you want and still be able to install HR-07 Duo which still incorporates the two-heatpipe design but having one set of radiator fins instead of two as in the original HR-07 for that fine balance between performance and space saving.

HR-07 Duo having one less set of radiator fins will of course not be as good as the original HR-07 but it will have more than enough cooling power to handle the heat from your memory chips. If you want the ultimate cooling power, we would definitely recommend HR-07. But if your system requires a great deal of memories, HR-07 Duo is your best bet.

you won't have to worry about space. Easy installation, no tools needed, able to install 4 DIMM, high cooling performance, and extends the life expectancy of your memory module. What more could you ask for?

Features:-

* Double heatpipes to double heatsinks for fast and efficient coolin
* Proprietary through holes on every fin for efficient ventilation in passive mode
* Vast compatibility across multiple types of memories
* No tools needed for an easy installation keeping manufacturer's warranty in tact without voiding it
* Supports Dual Channel Mode. Option to install on all four memory slots

Memory module Compatibilities

* DDR1/ DDR2 / DDR3 (only support duble sided memory module)

*with out ECC&FB-Dimm memory
Important Note: In order to install HR-07 Duo, you will have to remove the heat spreader on your memory module. However, Thermalright is not responsible for any problems or damages that may occur during the removal of memory heat spreader. Users will be at their own risk. If you are not sure or do not know how to remove/uninstall your heat spreader, please contact your memory manufacturer for instructions.

Also, I had no conflict with my Thermalright IFX-14 or Thermalright Ultra 120 Extreme

First Impressions:

Installation :-
My victims for this Overclocking experience






Apply the thermal tape on the RAM


slot it into the HR-07 and viola! its all done

Test Bed:

Processor: Intel C2D X6800 Extreme @ 3.6GHz @ 1.42 vcore
Motherboard: Foxconn MARS
RAM Module: aData DDR-2 667 9D9GMH Chipset0
Graphic Card: Foxconn 8800GT
Power Supply Unit : Silverstone Decathlon 1200W
Hard Disk: Western Digital 36Gb Raptor
Operating System : Windows XP Professional Service Pack 2

Results:-
These results are not faked in any way. They are all as real as they come
Max Obtainable without Thermalright HR-07 DUO

508mhz@2.21V CL4-4-4-9
Max obtainable results with Thermalright HR-07 DUO

530mhz@2.21V CL4-4-4-9

These A-Data RAMs are really awesome. 530mhz@2.21V CL4-4-4-9. Pretty darn good for some Value RAMs

Well, this is just for eyecandy


618mhz@2.17V Cl5-5-8-15

Now, this hits the spot. friggin 618mhz @ 2.17V. These rams are flying

Pros:-
-Definitely works!
-Looks nice in a high end system

Cons:-
-Not everyone may be able to afford these babies

Conclusion:-
These things really do work, well for my at least. They are easy to install, and did not clash with any of my heatsinks Put a fan over it, and you're all set to fly to the moon with your newly installed engine on your rams.

I award the HR-07 DUO a 8/10

A-data DDR 2 667
These RAMs are awesome. I got them to play around with and they were the cheapest D9GMH i could source in Lowyat.net
i managed to push them up to 630MHz @ 2.4V Cl5-5-5-15 but i totally forgot to take the screen shot. Ah well., maybe next time

A special thanks to Inter-Asia for the Thermalright HR-07 DUO
A special thanks to *you know who you are* for giving me a very attractive price on the A-DATA rams

nice review TS,
but one thing to ask,is the sink of the heat spreader got warm?

Good Review

Did you have a fan blowing on the RAM with and without the HR-07 Duo ?

A gain of 22MHz for the price of it not worth it IMHO. But I do recognize that it looks good. Particularly when you have other Thermalright stuff like CPU and VGA heatsink.

yeah it did get warm, thats the great part



well, when you are a serious overclocker, what you expect
plus, can you imagine pumping 2.5V into your rams naked?
its like pumping 1.6V into your proc with a stock heatsink. the chances of it dying is VERY high
yup, i did chuck a fan there

Nice review.... I wuz aiming 4 dat too... But, since i m noob at OCing rams... so.... Can it fit nicely or hav 2 move it 2 position??? It look abit big 2 me...

i believe it should fit nicely la, coz the big a** IFX14 is TR too. So the ppl would have figured the spacial difference to fit the coolers. But i am wondering how well will this work compared to Air which is airconditioned or a delta fan blowing onto the chips when OCing. Would that beat the HSpreaders even the TR in terms of cooling?

Surely at 2.5V, it's not good to run the RAM without good heatsink on them. Did you try such voltage with the RAM tested ?

yeah I did and my max was 650mhz

Adata does 1300Mhz. Wow, this is one sexy ram.

u raped tht rams sifu..really nice review..

rather than the heatspreaders.. im actually more interested on the rams in your entire review bro

Any idea where i could get 1 pair of those?

Great review eitherway

i belive u can ask bro jy14

@infan
thanks you. Already enquired from him. just waiting for a reply.

woah, seems like i should be sponsored by a-data eh?
but yes, i did 650mhz @ 2.51V @ CL5-5-5-15
i believe the PL was 7 incanse anyone wants to know how well the MARs performs

HAPPY CHINESE NEW YEAR TO ALL!

@dark
my team value 667Mhz rams have performance levels of 7 too.

wow!! very pretty ram heatsink!!

yalah, pretty price too. why dont you get one? i wanted to get one, but choose to use air cooling by blowing a fan instead onto the rams.

try tighter timings
i did 530mhz @ 2.21V @4-4-4-8

@dark
THAT i cant do thats gorgeous timings bro. Adata.. damn i wish i could have foreseen this coming than to spend over rm500 on finding the right value ram. How noob of me..

for GMH,u can do 2.6vdimm with 4-4-4-12 at 1200mhz.
i always did mine when running benchmark


but now i no longer interested in 2x1GB oc chip,i rather get myself 2x2GB for daily use.

wow....this cooler show d btter oc for me.ill buy this cooler soon.hehe

i dont think a cooler can save the ram if u r gonna pump 2.6V onto it just use a delta fan and blow the hell out of it.

Of course if u r looking at a 24/7 stable at probably 2.4V ddr2 1100 cl4 then this would be helpful.

look at it this way, if we could just use fans to blow the rams, why not use just fans to blow our proc?
matter of fact is, the chips will reach a certain point where they will be hot and it will come up to a point where fans dont work effectively anymore
well, i believe this heatsink was made for passive setups so you can avoid all those fans and cable mess.
just my 2 cents

@darky
theres no doubt that this coolers do their work and its also good that theres direct contact to a heat conductor that has heatpipes. but honestly i would not need this if i am only doing mid range OCing. If i am pumping 2.2V, a fan would do the job. but of course like i said, if ur doing a stable at 2.4V, then this would be helpful with the heatsink fan(proc), blowing some cool air at it

Processors cant be compared to rams bro. Layouts and electronics are different for both. Actually i am wondering whats the TDP for the rams. If we can compare TDPs then u will get a clear picture why its pretty important. Also remember that 486 chips aeons ago, infact even latter chips did not have cooling till the electronic design in the proc became more intricate and produced more heat.

bro got any CL3 result that pass SPI.. the max one

nope. i dont think i have any.
this review was quite some time back

so sad to hear that

but as far as i remember, it does around DDR8X0 CL3-3-3-8 @ 2.45V
if im correct la.
but this was a long time ago.

The reason heatsink is more efficient compared to a bare IHS is because air is a poor heat conductor. So the heat transfered from the IHS to the passing air is low.

This is when HSF comes into place. The aluminium/copper that comes into contact with the IHS transfers the heat to the fins. There they are transfered to the passing air. The difference is, the surface area of fin that transfers the heat is huge compared to the surface area of an IHS.
