How did G-SKILL do it?

post #1 of 15
Thread Starter 
I cant understand how G-skill made PC4800 without heatspreaders? Also, those timings are tighter than mine at PC3200! Crazy memory.

Can anyone shed more light?

Thanks.

G. Skill uses TCCD chips which can easily hit PC4800 speeds and TCCD only needs around 2.8v to do it. There's no mystery to it.

What is TCCD and BH5?

Sorry to invade thread.

TCCD and BH5 refer to the specific memory IC's that are used to make the RAM.

both TCCD and BH5 are some of the best overclocking memory that you can get.

they will both run DDR400 around 2-2-2-5
BH5 loves voltage so if your mobo can give it lots of juice it will run those same timings of 2-2-2-5 all the way up to about DDR500... it will probably need about 3.4v (I think)
TCCD doesn't like voltage over 3.0v and usually runs on about 2.8v or so. So if your mobo can't supply lots of juice TCCD is the best choice. TCCD will typically go to DDR600 with timings of about 2.5-4-4-8

my OCZ platinum rev. 2 uses Samsung TCCD chips and goes up to DDR640 at 2.5-4-4-8 timings. I currently am running it at DDR520 @ 2.5-3-3-7 with 2.85v.

Heat spreaders are a minimal means of radiating heat...
As Trans said they can run higher DDR ratings and maintain safe temps.
So, if you intened to OC, adding spreadders will help cool them. They simply avoided the cost of selling them with spreaders.

Acctualy, I fnd that for about the same price as heatspreaders, you can get 2 40mm fans and rubber-band them to the sides of the memory for far better cooling. By nature of being tight together and thus not having room for elaborite fin setups, heatspreader just can't be overly effective. (Now, heatspreaders and fans is a different story.. )

if you get gskill and arent worried about the warranty take the heat spreaders off and put some decent thermal tape on there (imo)

both sets of gskill that ive bought have had a 1/4" strip of heat tape (one was in the middle and the other was at the bottom of the sticks) that ran along the memory, which caused the rest of the heat spreader to not even touch the ram and infact leave a pretty big gap that im sure destroys any chance of working effectivly

I have never, ever felt RAM getting hot no matter what Ive done to it. Sometimes I wonder why they are called "heatspreaders" instead of "hide the info on the memory chips" covers.
